Thesis ((MPhil (Sustainable Development Management and Planning))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The main aims of this thesis were to investigate the benefits and limitations of local food economies in promoting sustainability through a review of the literature and an assessment of the current status of the food production, distribution and consumption in Stellenbosch in order to make recommendations for promoting greater sustainability through Stellenbosch‟s food system. A review of the literature found that the modern food system has promoted the externalisation of social and environmental costs to the detriment of food, livelihood and environmental security for communities across the world. Whilst localisation of the food system does not conclusively result in reduced contributions to greenhouse gas emissions, it tends to promote greater sustainability through the building of community networks and embeddedness that increase the potential for strengthening community resilience, accountability and the internalisation of social and environmental costs. Challenges in the near future of population growth, urbanisation, climate change, intensifying environmental degradation and peak oil are expected to drastically alter the ways in which we are able to produce and distribute food. Local food economies are presented as an alternative food system that builds social, economic and environmental capital at a community level whilst increasing community resilience to future shocks and threats. Research into the current status of production, distribution and consumption for Stellenbosch found that the region currently produces predominantly wine grapes and other deciduous fruit for export, whilst relying on imported food produce from other regions for consumption. High levels of food insecurity are recorded for areas within Stellenbosch and findings are presented on the food requirements for a nutritionally optimal diet for the region. Productive potential of the land and urban zones are translated into potential yield and compared with current and nutritionally optimal food demand. The findings suggest that Stellenbosch has the potential to produce enough food to meet all local requirements (both current and nutritionally optimal) but this would require drastic shifts in land use. A discussion is presented on optimal land use, comparing production of wine grapes for export with food production for local consumption. The conclusions drawn from the thesis suggest that in the context of current food, livelihood and environmental insecurity and future vulnerability as a result of increasing demand, climate change and peak oil, local food economies have a vital role to play in promoting sustainability. Stellenbosch is currently vulnerable with a high dependency on export markets for local produce and imported produce for local consumption. Building a stronger local food economy in Stellenbosch has the potential to create opportunities to address challenges of poverty and inequality, build resilience and promote environmental sustainability. The recommendations of the thesis are to boost local production of key food crops suitable to the region, actively invest in the strengthening of local distribution networks that connect local producers more directly to local consumers and to build a local food movement with consumers through education and awareness. Several opportunities for further scholarship are presented. / AFRIKAANSE OPSOMMING: Die hoofdoel van hierdie tesis is om voedselekonomieë as 'n instrument van volhoubaarheid aan te moedig. Spesifiek gekose literatuur en 'n ondersoek na die huidige voedselproduksiesituasie, verspreiding en die verbruik van voedsel in Stellenbosch is gebruik om voorstelle te maak vir verhoogde volhoubaarheid in die toekoms deur die gebruik van die voedselsisteem in Stellenbosch. Uit die literatuurstudie is gevind dat moderne voedselsisteme neig na die eksternalisasie van sosiale- en omgewingskostes en dus die sekuriteit van voedsel, lewensonderhoud en 'n gesonde omgewing vir gemeenskappe reg oor die wereld bedreig. Die lokalisering van voedselsisteme beteken nie noodwendig dat die vrystelling van uitlaatgasse wat tot aardverwarming bydra verminder word nie, maar dit dra wel by tot volhoubaarheid deur gemeenskapsnetwerke en gemeenskapsbande te versterk. Sterker gemeenskappe dra verder by tot meer veerkragtige herstel en moedig aanspreeklikheid en die internalisasie van sosiale- en omgewingskostes aan. Uitdagings in die nabye toekoms, soos populasiegroei, verstedeliking, klimaatsverandering, die intensifisering van omgewingsdegradering en die olie-piek, gaan die manier hoe voedsel geproduseer en versprei word drasties verander. Plaaslike voedselekonomieë word dus as 'n alternatiewe voedselsisteem voorgestel, omdat dit sosiale-, ekonomiese- en omgewingskapitaal opbou op gemeenskapsvlak en dit 'n meer veerkragte herstelvermoë gee om effektief te reageer op toekomstige skokke en bedreigings. Navorsing oor die huidige produksie, verspreiding en gebruik van voedsel in Stellenbosch het bevind dat die streek hoofsaaklik wyndruiwe en ander sagte vrugte produseer vir die uitvoermark, terwyl dit op invoere staatmaak vir plaaslike gebruik. Hoë vlakke van voedselonsekerheid in areas in en om Stellenbosch is aangeteken en die bevindinge word aangebied in terme van die optimale voedsame dieet vir die omgewing. Die potensiaal vir die produktiwiteit van landelike en stedelik gebiede in Stellenbosch word vertaal as die potensiële oes en word vergelyk met huidige en die optimale voedsame voedsel aanvraag. Daar is in die navorsing bevind dat Stellenbosch die potensiaal het om genoeg voedsel te produseer om in alle plaaslike vereistes (beide huidiglik en optimaal voedsaam) te voldoen, met 'n drastiese verandering in grondgebruik. Voorstelle word v gemaak oor die optimale gebruik van grond deur die produksie van wyndruiwe vir uitvoer te vergelyk met voedselproduksie vir plaaslike gebruik. Die gevolgtrekkings dui daarop dat die huidige voedsel-, lewensonderhoud- en omgewingsonsekerheid, tesame met 'n toekomstige kwesbaarheid as gevolg van verhoogde aanvraag, klimaatsverandering en die olie-piek, beteken dat plaaslike ekonomieë 'n belangrike rol gaan speel in volhoubaarheid. Stellenbosch is tans kwesbaar omdat dit staatmaak op uitvoer van plaaslike produkte en op ingevoerde produkte vir plaaslike gebruik. Deur 'n sterker plaaslike voedselsisteem te bou, kan Stellenbosch geleenthede skep om armoede en ongelykheid aan te spreek, 'n veerkragtige herstelvermoë te bou en omgewingsvolhoubaarheid aan te moedig. Die voorstelle in hierdie tesis sluit in om plaaslike produksie van sleutel voedselgewasse wat volhoubaar is te verhoog, om aktief te bele in die versterking van plaaslike verspreidingsnetwerke wat plaaslike produseerders en gebruikers direk verbind en om 'n plaaslike voedselbeweging daar te stel deur gepaste opvoeding en bewusmaking. Verskeie geleenthede bestaan vir verdere navorsing.

Thesis (MPhil (Sustainable Development, Planning and Management))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: Sustainable agricultural management practices have a profound impact on soil carbon sequestration. The amount of carbon that can be stored in a given soil is influenced by climate, soil type, and the quality and quantity of organic inputs. Together, the interactive effect of these factors determines the Soil Organic Content (SOC). Sustainable agricultural management practices influencing Soil Organic Matter (SOM) include application of organic amendments, conservation tillage, and use of cover crops, crop rotations, crop residue management, and nutrient management. Increasing SOC enhances soil quality, reduces soil erosion, and increases agricultural productivity with considerable on-farm and off-farm benefits. To assess how management practices affect SOC, two case studies were conducted in Yavatmal district of Maharashtra in India and Lynedoch near Stellenbosch. The first case study examined the differences in SOC content on four farms each managed with 13 different sustainable agricultural techniques and one farm managed under conventional management practices. The second case study investigated the SOC differences between an organic and a conventional vegetable farm. The results of both studies show that farms that are managed under sustainable agricultural practices generally contain higher SOC content than farms that are managed under conventional agricultural practices. / AFRIKAANSE OPSOMMING: Om te bepaal hoe bestuurspraktyke Grondlikke Organise Koolstoff raak, is twee gevallestudies in die distrikte Yavatmal in Maharashtra, Indië, en Lynedoch buite Stellenbosch uitgevoer. Die eerste gevallestudie het die verskille in Grondlikke Organise Koolstoff -inhoud bekyk op vier plase waar 13 verskillende Volhoubare landboubestuurspraktyke het ‟n diepgaande impak op grondkoolstof-beslaglegging. Die hoeveelheid koolstof wat binne gegewe grond gestoor kan word, word deur klimaat, grondsoort en die gehalte en hoeveelheid organiese toevoer beïnvloed. Saam bepaal die interaktiewe effek van vermelde faktore die Grondlikke Organise Koolstoff -inhoud. Volhoubare landboubestuurspraktyke wat Grondlikke Organise Materiaal beïnvloed, sluit in die toediening van organiese verbeterings, bewaringsgrondbewerking, die gebruik van dekkingsoeste, oesrotasies, die hantering van oesresidu en voedingstofbestuur. Vermeerdering van Grondlikke Organise Koolstoff verhoog grondgehalte, verminder gronderosie en vermeerder landbouproduktiwiteit met aansienlike voordele op en verwyderd van die plaas. volhoubare landboutegnieke in die bestuurproses toegepas word, en een plaas wat volgens konvensionele bestuurspraktyke bedryf word. Met die tweede gevallestudie is ondersoek gedoen na die Grondlikke Organise Koolstoff -verskille tussen ‟n organiese en ‟n konvensionele groenteplaas. Die uitslae van albei studies dui daarop dat plase wat volgens volhoubare landboupraktyke bestuur word oor die algemeen hoër Grondlikke Organise Koolstoff-inhoud aantoon in vergelyking met plase wat volgens konvensionele landboupraktyke bedryf word.

Thesis (MPhil)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This thesis investigates practical approaches to growing sustainable food systems. It first establishes the condition of the global environment within which food systems function and critically assesses previous efforts to grow sustainable food systems. After applying these findings to a set of case studies on local-food distribution in Stellenbosch, I recommend ways for the local-food distribution network to encourage the growth of a sustainable Stellenbosch food system. The literature review provides an overview of the global environment in relation to food systems and lists certain contextual challenges that food systems must address to become sustainable. These challenges are social inequality, an urban future, degraded ecosystems, climate change, energy constraints, a growing global population and food insecurity. The literature review also describes how commercialisation has disembedded food systems from their contexts. This disembeddedness loosens the feedback loops food systems require to effectively respond to contextual challenges and consequently hinders their sustainability. The critical overview of previous attempts to re-embed food systems provides insight into practical ways of growing sustainable food systems. The overview demonstrates that while localisation and the building of social capital should not be seen as the ultimate goals of sustainable food systems, they can be useful mechanisms for nurturing sustainability if applied carefully. The case studies describe ten local-food distribution initiatives in Stellenbosch, and are informed by numerous in-depth semi-structured interviews. My conceptual framework contrasts each initiative’s self-reported vision, perceived reality, and realised actions; this highlights the conceptual and physical network connections between various local-food distribution initiatives, as well as the factors preventing and promoting their sustainability. The case studies show that although a local-food distribution network exists in Stellenbosch, it is fragile and lacks defined conceptual connections. This in turn constrains the formation of physical connections and thus the food system’s progress toward sustainability. The local-food distribution network in Stellenbosch can catalyse the growth of a sustainable food system because its initiatives focus on localisation but do not see it as a final objective. This shared focus indicates that localisation already constitutes a practical tool in the growth of a sustainable food system; however, the network’s lack of social capital still needs to be addressed. Inclusive projects designed to create and protect intellectual, political and economic spaces for reflection within the food system can generate the social capital necessary to grow a sustainable food system. The realisation of a sustainable Stellenbosch food system therefore depends on those with the capacity and resources to initiate the necessary changes. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek praktiese benaderings waarmee volhoubare kossisteme bevorder kan word. Dit stel eerstens die toestand van die globale omgewing waarin kossisteme funksioneer vas en oorweeg krities vorige pogings wat volhoubare kossisteme probeer bevorder het. Na ek hierdie bevindings toepas op ’n stel gevallestudies van inisiatiewe wat plaaslik-geproduseerde kos in Stellenbosch versprei, kom ek met voorstelle vorendag vir dié verspreidingsnetwerk om die groei van ’n volhoubare Stellenbosch-kossisteem aan te moedig. Die literatuurstudie omskryf ’n oorsig van die globale omgewing met betrekking tot kossisteme en lys sekere kontekstuele uitdagings wat kossisteme moet aanspreek om volhoubaar te wees. Die uitdagings is maatskaplike ongelykheid, ’n verstedelikte toekoms, verswakte ekosisteme, klimaatsverandering, energiebeperkings, ’n groeiende globale bevolking en voedselonsekerheid. Die literatuurstudie bepaal ook dat kommersialisering kossisteme uit hulle omgewings ontwortel. Hierdie ontwortelling verswak die terugvoerbane wat kossisteme benodig om effektief op kontekstuele uitdagings te reageer en verhoed hulle volhoubaarheid. Die kritiese oorsig van vorige pogings om kossisteme nuwe wortels te laat skiet gee insig tot praktiese maniere om volhoubare kossisteme te bevorder. Die oorsig wys daarop dat terwyl lokalisering en die bou van maatskaplike kapitaal nie as die slotsom van volhoubare kossisteme beskou moet word nie, albei nuttige tegnieke kan wees vir die aankweek van volhoubaarheid indien hulle met sorg aangewend word. Die gevallestudies beskryf tien verspreidings-inisiatiewe van plaaslik-geproduseerde kos in Stellenbosch en is ingelig deur verskeie in-diepte, semi-gestruktureerde onderhoude. My konsepsuele raamwerk kontrasteer elke gevallestudie se self-verklaarde visie, veronderstelde realiteit en gerealiseerde aksies. Dit lig die begrips- en fisiesenetwerkkonneksies tussen die inisiatiewe uit en stel ’n aantal faktore bloot wat die netwerk se volhoubare groei positief en negatief beïnvloed. Die gevallestudies wys daarop dat alhoewel ’n verspreingsnetwerk van plaaslik-geproduseerde kos in Stellenbosch bestaan, dié netwerk swak is en omskrewe begripskonneksies kort. Om die beurt verhinder dit die formasie van fisiese konneksies en weerhou die kossisteem se vordering na volhoubaarheid. Die verspreidingsnetwerk van plaaslik-geproduseerde kos in Stellenbosch kan die groei van ‘n volhoubare kossisteem kataliseer omdat die inisiatiewe waaruit dit bestaan deur ’n gemeenskaplike fokus op lokalisering verbind word, maar dit nie as hulle einddoel beskou nie. Hierdie gedeelde fokus wys daarop dat lokalisering reeds ’n bruikbare tegniek vir die groei van ‘n volhoubare kossisteem is, maar die tekort aan maatskaplike kapitaal binne die netwerk moet steeds aangespreek word. Inklusiewe projekte wat saamgestel word om intellektuele, politiese en ekonomiese ruimtes vir besinning binne die kossisteem te bevorder en te bewaar, kan die nodige maatskaplike kapitaal kweek om ’n volhoubare kossisteem te vestig. Die verwesenliking van ’n volhoubare Stellenbosch-kossisteem hang dus van diegene af wat die kapasiteit en hulpbronne het om die nodige veranderings in te lei.

Thesis (MPhil)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: The aim of this thesis was to determine whether or not examples exist of commercial grain farmers in the Swartland region of South Africa moving away from high-external-input agricultural production systems towards production systems based on ecologically restorative partnerships with soils and other natural systems. The research also sought to understand why these farmers were changing their approach to farming, as well as investigating the specific technologies and practices they were implementing in order to achieve these changes. In addition, the thesis also considered the theoretical implications of these changes on food security in the Western Cape. Three research approaches were employed: qualitative case studies of seven progressive farmers in the region; a literature review; and an analysis of secondary data. Throughout these three approaches, Swilling and Annecke’s conceptualisation of a multifaceted global polycrisis was used as a conceptual reference point. This was done with the intention of providing an agricultural analysis which looks beyond the farm gate and takes cognisance of the broader socio-ecological issues which affect and are affected by agriculture. The research identified seven farmers who are shifting towards lower-external-input production methods, which focus on enhancing beneficial partnerships with natural systems. The on-site interviews and observations revealed that the degree to which these seven farmers were altering their practices varied significantly. However, four key technologies and practices were identified as being common to all seven farmers: the use of legume rotations, reduced tillage, new styles of planters and increasing farm size. With regard to food security, the research suggested that current changes in these farmers’ agricultural practices could assist in keeping food prices and food production levels more stable in future, compared to production using high-external-input practices previously employed by the farmers. The potential improvement in production stability was shown to result mainly from improvements in soil health, as these improvements give crops increased resilience to unfavourable weather conditions, greater disease-resistance and improved vitality. The potential improvement in price stability stemmed predominantly from increased input-use efficiency and the utilisation of natural fertility and pest-management practices which were less susceptible to monopolistic input sales structures, international shortages and the increasing cost of fossil fuels. Due to the small size of the case study sample and the fact that this research focussed specifically on farmers who were considered progressive, the findings presented in this thesis cannot be viewed as representative of the larger agricultural region. The intention was rather to establish the positive changes currently underway, in order to provide useful pointers for similarly beneficial changes to be implemented elsewhere. / AFRIKAANSE OPSOMMING: Die doel van hierdie tesis was om vas te stel of voorbeelde bestaan van kommersiële graanboere in die Swartlandgebied van Suid Afrika wat wegbeweeg van hoë-eksterne-inset produksie sisteme na sisteme wat gebasseer is op vennootskappe met grond en ander natuurlike sisteme. Die doel van dié vennootskappe isom ekologiese herstellingte bewerkstellig. Die navorsing het ook gepoog om te verstaan hoekom hierdie boere hulle boerderytegniekeverander; spesifieke tegnologieë en praktyke wat gebruik word om verandering mee te bringis ondersoek. Daarenbowe oorweeg hierdie tesis ook die teoretiese implikasies van die veranderings op voedselsekuriteit in die Wes-Kaap. Drie navorsings benaderings is te werk gestel: kwalitatiewe gevallestudies van sewe vooruitstrewende boere in die area; ‘n literatuurstudie; en ‘n analise van sekondêre data. Swilling en Annecke se konsepsualisering van die veelvoudig-gefasetteerde globale polikrisis is deurlopend gebruik as ‘n konsepsuele verwysingspunt. Dit is gedoen om‘n boerdery analise daar te stel wat verby die plaashek kyk na wyer maatskaplike en ekologiese kwessies wat ‘n wederkerige verhouding met boerdery het. Die navorsing het sewe boere geidentifiseer wat na laer-eksterne-inset produksie metodes beweeg. Hierdie metodes fokus daarop om voordelige verhoudings met natuurlike sisteme te versterk. Onderhoude en waarnemings op die plase het vasgestel dat die graad van praktykverandering merkwaardig tussen die sewe boere verskil. Nietemin, vier gemeenskaplike sleuteltegnologieëenpraktyke is geidentifiseer: die rotasie van peulgewasse, verminderde grondbewerking, nuwe plantermodelle en die vergroting van plaasgroottes. Met betrekking tot voedselsekuriteit vind die navorsing dat huidige veranderings in die wyse waarop geboer word, in vergelyking met die voorafgaande hoe-eksterne-inset produksie praktyke, kospryse en produksievlakke kan stabiliseer. Die navorsing wys daarop dat ‘npotensiële verbetering in produksie stabiliteit ‘n uitkoms van gesonder grond is. Gesonder grond verhoog gewasse se vermoëom effektief op ongunstige weerkondisies te reageer, bevorder hulle pes-afweringvermoë en verbeter die lewenskragtigheid van gewasse. Die potensiele verbetering in die stabiliteit van pryse is ‘n nagevolg van meer effektiewe gebruik van insette en die gebruik van natuurlike vrugbaarheid en pesbestuurpraktyke wat minder vatbaar is vir monopolistiese inset-verkoopstrukture, internasionale tekorte en die prysverhoging van fossielbrandstowwe. Na aanleiding van die klein skaal van die gevallestudies en die feit dat die navorsing spesifiek gefokus het op vooruitstrewende boere, verteenwoordig die bevindings in hierdie tesis nie die omliggende landbou area nie. Die veronderstelling was eerder om die positiewe veranderings wat tans onderweg is vas te stel om sodoende bruikbare advies aan soortgelyke voordelige veranderings wat elders geimplementeer kan word te verskaf.

Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: This thesis investigated the issues that rural smallholder women face in accessing markets in developing countries. Market access for rural smallholder farmers is increasingly being promoted as a means towards catalysing sustainable rural development. However, without addressing the gender specific issues that rural smallholder women farmers face in accessing markets, market access as a strategy towards sustainable rural development may fail to achieve its ends. This thesis gathered evidence from a group of smallholder women farmers in Chirumanzu, Zimbabwe, who are part of a market access project run by Oxfam, in order to highlight the issues that they face in accessing markets for their produce. Primary and secondary data were used in the study. First, a literature review was conducted to assess the issues that smallholder rural women farmers in developing countries face in accessing markets and how the issues differ to those faced by male smallholder farmers. A thematic assessment of the issues was conducted, beginning with the production for market through to the actual market engagement. Secondly, primary data was collected in Chirumanzu, from rural smallholder women farmers who are participating in a market access project being facilitated by Oxfam. Data was collected through focus group discussions, key informant interviews and document review. Five focus group discussions were held with a total of 40 participants in August 2011. Some of the key findings were that rural smallholder women farmers face challenges in terms of meeting the labour demanded for market production, accessing market information and having to contend with high transport costs. The data was then compared with the points raised in the literature review. The comparison showed that most of the key issues raised in the Chirumanzu case study were similar to those identified in the literature review. The study came to the conclusion that rural smallholder women farmers face different issues and more challenges in accessing markets compared to male farmers. Market access initiatives that do not recognise and address the gender specific challenges that women smallholder farmers face may therefore not be catalysts for sustainable rural development. Therefore recommendations are that market access initiatives should go beyond facilitating access to markets to address the structural social, economic and cultural issues that present special challenges and constraints to women smallholder farmers. / AFRIKAANSE OPSOMMING: Hierdie tesis het ondersoek ingestel na die kwessies waarvoor landelike vrouekleinboere in ontwikkelende lande te staan kom om toegang tot markte te verkry. Marktoegang vir landelike kleinboere word toenemend aangemoedig as ’n manier om volhoubare landelike ontwikkeling teweeg te bring. Indien die geslagspesifieke kwessies van marktoegang waarmee landelike vrouekleinboere te kampe het egter nié hanteer word nie, kan marktoegang as strategie vir volhoubare landelike ontwikkeling in gebreke bly om sy doel te bereik. Hierdie tesis het bewyse ingesamel van ’n groep vrouekleinboere in Chirumanzu, Zimbabwe, wat deel is van ’n marktoegangsprojek deur Oxfam, ten einde die soeklig te werp op die uitdagings wat hulle ervaar om marktoegang vir hul produkte te bekom. Die studie het van primêre sowel as sekondêre data gebruik gemaak. Eerstens is ’n literatuuroorsig onderneem om te verken watter probleme landelike vrouekleinboere in ontwikkelende lande ondervind om marktoegang te verkry, en hoe dit verskil van die uitdagings waarvoor hul manlike eweknieë te staan kom. Die kwessies is tematies beoordeel en het gestrek van markgerigte produksie tot en met werklike markskakeling. Tweedens is primêre data ingesamel onder landelike vrouekleinboere in Chirumanzu wat aan ’n marktoegangsprojek deur Oxfam deelneem. Data is deur middel van fokusgroepbesprekings, onderhoude met sleutelinformante sowel as ’n dokumentoorsig bekom. Vyf fokusgroepbesprekings is in Augustus 2011 met altesaam 40 deelnemers gehou. Van die belangrikste bevindinge was dat landelike vrouekleinboere bepaald uitdagings ervaar wat betref die vereiste arbeid vir markgerigte produksie, toegang tot markinligting sowel as hoë vervoerkoste. Daarná is die data met die hoofpunte uit die literatuuroorsig vergelyk. Die vergelyking toon dat die meeste van die kernbevindinge in die Chirumanzu-gevallestudie met die bevindinge in die literatuuroorsig ooreenstem. Die studie kom tot die gevolgtrekking dat landelike vrouekleinboere voor andersoortige kwessies en meer uitdagings as hul manlike eweknieë te staan kom ten einde marktoegang te verkry. Marktoegangsinisiatiewe wat nié hierdie geslagspesifieke uitdagings van vrouekleinboere erken en hanteer nie, kan dus in gebreke bly om waarlik volhoubare landelike ontwikkeling teweeg te bring. Daarom beveel die studie aan dat marktoegangsinisiatiewe oor méér as die blote fasilitering van marktoegang handel, en ook aandag skenk aan die strukturele maatskaplike, ekonomiese en kulturele kwessies wat besondere uitdagings en beperkings vir vrouekleinboere inhou

Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: In recent years, a great deal of attention has been paid towards the notion of corporate sustainability, which has variously been defined as meaning the incorporation of social, environmental, economic, and cultural concerns into corporate strategy and bottom line. The preliminary investigation suggests that Multi-National Corporations (MNCs) are mainly worried about securing permission for commencing operations and not about the wellbeing of locals and their livelihoods. Further to this, one of the main reasons why efforts aimed at improving sustainability are not yielding significant and lasting results, is that solution seekers in business, science, government and the research community are still operating in the same old paradigm of using basically the same tools and adopting the same world view that threaten sustainability in the first. The key and clear research objectives of this study are:- to ascertain if there is a link between British American Tobacco Zimbabwe (BATZ) top management philosophy, corporate strategy and the company`s corporate sustainability programmes, initiatives and other efforts, and the various stakeholders, and, if so, how these are communicated to them; to establish the degree of integrating sustainable development practice and initiatives into the BATZ business model in order to have long term benefits for both the company and its various stakeholders - these are an integral part of the socio-ecological system, and will help the business understand the resilience of the system and where in the system they should operate; to establish the depth, scope and culture of sustainability in terms of the extent to which they inserted inside (embedded) the BATZ operations; and to ascertain the level of economic, social and environmental effects of BATZ`s corporate sustainability programmes and initiatives in the locality in which it operates. The research used focus group and key informant discussions, one-on-one interviews, and to a limited extent a semi-structured research questionnaire. Information was also accessed from company internal information management portals, and BATZ’s group sustainability and other reports. The conclusion was that renewable energy programmes at BATZ were driven by energy insecurity and scarcity. Currently BATZ is not recycling water used in cigarette manufacturing operations, waste recycling of cut-rag tobacco has been occurring, and BATZ will continue to provide agronomic support to small scale farmers under its Social Responsibility in Tobacco Programmes (SRTP) towards leaf sustainability. The Rocket Barn concept is one of the most innovative intermediate technological breakthroughs meant for improving wood fuel efficiency in tobacco curing. Socially BATZ has done some good works in addressing some of society’s key challenges. There have been benefits for key corporate stakeholders in having BATZ operating in Zimbabwe. The research will assist BATZ to fully understand the socio-ecological system in which it operates; a fundamental understanding to improve corporate sustainability, which will then require a shift in sustainability-oriented efforts. / AFRIKAANSE OPSOMMING: Die idee van korporatiewe volhoubaarheid het die afgelope klompie jare baie aandag geniet. Wyd gesien, kom definisies neer op die insluiting van maatskaplike, omgewings-, ekonomiese en kulturele ondernemings in basiese korporatiewe strategieë. Die voorlopige ondersoek stel voor dat MNK’s wel gemoeid is met die verkryging van toestemming om bedrywe te stig, maar nie juis die welsyn en dag-tot-dag-belange van die plaaslike gemeenskap op die hart dra nie. Volgens (Fiksel 2003) en Du Plessis (2008) is een van die hoofredes waarom pogings om volhoubaarheid te verbeter nog nie betekenisvolle en blywende resultate gelewer het nie, die feit dat die mense betrokke by sake-ondernemings, wetenskap, die regering en navorsing wat na oplossings soek, nog geen paradigmaskuif gemaak het wat hul denkpatrone betref nie. Hulle gebruik steeds dieselfde uitgediende gereedskap en huldig nog dieselfde wêreldsienings wat volhoubaarheid in die eerste plek bedreig het. (Fiksel, 2003, Du Plessis, 2008, Hayward et al 2010). Die doelwitte van die navorsing is: om uit te vind of daar ’n skakel is tussen die filosofie en korporatiewe strategie van BATZ-hoofbestuur en die maatskappy se volhoubaarheidsprogramme, inisiatiewe ens; om te bepaal in watter mate volhoubare ontwikkeling en volhoubaarheidspraktyke en inisiatiewe geïntegreer word in die BATZ-korporatiewe model, om impak vas te stel en die kultuur van volhoubaarheid binne BATZ-bedrywe te bepaal. Die navorsing het gebruik gemaak van fokusgroepe, van sleutelbesprekings deur ingeligte persone, een-tot-een-onderhoude en in enkele gevalle selfs van gestruktureerde vraelyste. Toegang tot inligting is ook verkry deur middel van ‘n maatskappy se interne inligtingsbestuursbronne, BAT-groep-volhoubaarheids- en ander verslae. Die gevolgtrekking is dat hernubare energieprogramme afgedwing is op Batz deur die onsekerheid oor en die gebrek aan energie. Tans word water wat in sigaretbedrywe gebruik word nie deur BATZ herwin nie, maar afval van “cut-rag” tabak word wel herwin, en BAT Zimbabwe sal voortgaan met agronomiese ondersteuning aan kleinskaalboere kragtens sy Maatskaplike Verantwoordelikheid t.o.v. Tabak Programme (MVTP) vir blaarvolhoubaarheid. Die “Rocket Barn-”konsep is een van die innoverendste intermediêre tegnologiese deurbrake om die effektiwiteit van houtbrandstof by die droogmaak van tabak te verbeter. Op maatskaplike vlak het BATZ Zimbabwe goeie werk gedoen deur enkele uitdagings van die gemeenskap die hoof te bied. Die feit dat BAT in Zimbabwe werksaam is, was tot voordeel van korporatiewe belangstellendes. Die navorsing sal BATZ help om die sosio-ekologiese stelsel waarvolgens dit bedryf word, ten volle te verstaan, en om korporatiewe volhoubaarheid te bevorder, wat dan ‘n kopskuif ten opsigte van volhoubaarheidsgeöriënteerde pogings sal vereis.

O objetivo desta pesquisa foi refletir sobre a dimensão feminina na campesinidade e a importância de sua valorização para a incorporação dos aspectos sócio-culturais na prática agroecológica. A agroecologia pode ser definida como um campo de estudos de caráter multidisciplinar, que tem como objetivo articular o saber-fazer científico ao saber-fazer das comunidades rurais, como forma de potencializar práticas sustentáveis de agricultura. Como movimento de oposição ao processo de modernização da agricultura, busca recuperar as condições socioambientais perturbadas por este e viabilizar a construção de uma realidade sustentável. Contudo, tem-se constatado atualmente que a prática agroecológica brasileira tem sido realizada de maneira restrita, limitando-se principalmente a aspectos técnicos, insuficiente à realização da transformação pretendida teoricamente. Neste trabalho analisou-se, portanto, as possibilidades da campesinidade, e particularmente a valorização da sua dimensão feminina, contribuir para efetivar o projeto agroecológico de construção da sustentabilidade. Para tanto, realizou-se: (1) um estudo sobre as diferentes concepções teóricas da agroecologia e suas possibilidades de articulação para construção de uma proposta de agroecologia plena; (2) uma análise teórica sobre o campesinato e as características da campesinidade, de uma perspectiva de gênero, como fundamentação para a pesquisa de campo; (3) análises empíricas sobre campesinidade, relações de gênero na unidade familiar de produção e prática agroecológica, em duas realidades distintas: a região do Vale do Ribeira/SP e o município de Joanópolis/SP; e finalmente, (4) uma reflexão sobre as potencialidades de contribuição da dimensão feminina e da campesinidade para a construção da agroecologia plena. A pesquisa de campo foi realizada através de observação participante e realização de entrevistas abertas, buscando diversas formas de reduzir a distância existente entre pesquisadores e pesquisados. Como conclusão, constatou-se que (1) o processo de modernização da agricultura causou efeitos perturbadores à campesinidade e às relações de gênero, mas que, ainda assim, (2) é possível encontrar elementos de campesinidade nas realidades transformadas por esse processo. No entanto, (3) as iniciativas agroecológicas estudadas não alcançaram as condições necessárias para transcender os efeitos desta modernização sobre a organização sócio-cultural camponesa, especialmente no que se refere à masculinização dos processos familiares de produção. Finalmente, sugeriu-se que, quanto ao procedimento metodológico, a antropologia tem muito a contribuir com a construção de uma agroecologia plena. / The aim of this research was to reflect about the feminine dimension inside rural communities and the importance of feminine valorization looking to incorporate socio cultural aspects in agroecological practice. Agroecology can be defined as a multidisciplinary field of study that aims to articulate the scientific know-how with the rural communities know-how, as a way to strengthen sustainable practices in agriculture. As an opposition movement against the agricultural modernization process, it seeks to recover socio environmental conditions disturbed by it and facilitate the construction of a sustainable reality. However, it has been confirmed that agroecolgy has been practiced in a restricted way, limiting it to technical aspects that are not enough to reach the aimed theoretical transformation. Therefore, the contribution of rural communities, especially regarding feminine valorization was analyzed looking to see its contributions to the execution of an agroecological project for the construction of sustainability. Looking to achieve the objectives of this research, the following analysis were made: (1) a study about the different theoretical conceptions about agroecolgy and its articulation possibilities to construct a full agroecological proposal; (2) a theoretical analysis about rural communities and its characteristics from a gender perspective, as the basis for the field study; (3) empirical analysis about rural communities, gender relations inside the family production unit and agroecological practice in two different realities: Vale do Ribeira region SP, Brazil and Joanópolis municipality SP, Brazil; finally, (4) a reflection about the potentialities of feminine dimension contribution and of rural communities for the construction of a full agroecolgy. Field research was carried out by means of participant observation and open interviews, looking to reduce the distance between the researcher and the researched in several ways. To conclude it can be stated that (1) the agriculture modernization process caused disturbing effects to rural communities and to gender relations, but, even so (2) it is possible to find rural elements in the realities modified by this process. However, (3) the analyzed agroecological initiatives did not achieve the necessary conditions to transcend the effects of this modernization inside the rural socio cultural organization, especially regarding the masculinization of family production processes. Finally, it is suggested that anthropology can make a great contribution to the construction of a full agroecolgy, regarding the methodological procedure.

A agropecuária brasileira apresenta relevante papel sócio-econômico para o país, e constantemente busca novas tecnologias para alcançar uma agricultura sustentável. Com as mudanças que vêm ocorrendo no uso da terra, principalmente nas regiões tropical e subtropical, o Brasil vem sendo apontado como um grande emissor dos gases do efeito estufa. A conversão de florestas em sistemas agrícolas pode levar a um rápido aumento dos fluxos de CO2, CH4 e N2O no ambiente, além de potencializar o efeito estufa e ameaçar os diferentes ecossistemas. Em busca de sistemas mais conservacionistas, que possam mitigar o efeito estufa, os sistemas convencional, plantio direto, integração lavoura-pecuária e pastagem com histórico bem definido, foram selecionados nesse estudo para melhor compreensão e discernimento das possíveis mudanças oriundas dos sistemas avaliados no bioma do Cerrado. Em um segundo momento avaliamos o potencial da elevada concentração de CO2 aquecimento das parcelas em sistema sob temperature freeair controlled enhancement e carbon dioxide free-air enrichment (T-FACE) para avaliar as alterações funcionais e composição microbiana do solo. Os objetivos desse estudo foram: determinar a quantidade de células total dos genes 16S rRNA bactéria, archaea e dos genes funcionais amoA, nirS, nirK, cnorB, nosZ, presentes em diferentes sistemas de manejo do solo. Bem como, possíveis alterações na comunidade microbiana do solo sob elevada concentração de CO2 e aquecimento das parcelas. Para acessar o número de cópias dos genes foi utilizado o PCR quantitativo, a estrutura da comunidade microbiana foi determinada pela técnica de T-RFLP e a composição microbiana pelo sequenciamento de terceira geração. Os resultados dos sistemas de plantio direto e integração lavoura-pecuária revelaram importante capacidade de controlarem as emissões de N2O. Notoriamente, o número de cópias do gene nosZ teve sua densidade incrementada nos dois sistemas de plantio direto e integração lavoura-pecuária, este gene apresenta alto potencial para monitorar a desnitrificaçnao completa do N2O a N2. Adicionalmente, a elevada concentração de CO2 e elevada temperatura incrementaram o número de cópias dos genes nifH, AOB e nosZ ao longo do experimento. A análise da diversidade dos grupos taxinômicos e funcional revelou que a diversidade funcional foi alterada nas parcelas com maior emissão de N2O, apresentando maior abundância de genes (2-3 vezes) envolvidos na desnitrificação, acarretando possivelmente essas maiores emissões de N2O pela microbiota do solo. / Agriculture activities have large an important socio-economic role for a country, and are constantly searching for new technologies to achieve sustainable agriculture. Changes have occurred in land use, especially in tropical and subtropical regions and Brazil has been considered as a large emitter of greenhouse gases from agricultural systems. The conversion of forests to agricultural systems can lead to a fast increase of CO2 streams, CH4 and N2O for atmosphere, which enhances the greenhouse effect and threaten the ecosystem. In search of more conservation systems that can mitigate the greenhouse gas, the conventional, no-tillage, integrated crop-livestock and pasture systems with well defined historical management were selected in this study to better understand and decifer the possibles changes resulting in the biome Cerrado. In a second study, it was evaluated the potential of high concentration of CO2 and warming plots on system under increased temperature free-air controlled enhancement e carbon dioxide freeair enrichment (T-FACE) to assess the functional changes and microbial composition in the soil. The objectives of this study were to determine the total amount of the 16S rRNA Bacteria, Archaea and the functional genes amoA, nirS, nirK, cnorB, nosZ present under different soil management and evaluate the possible changes in the soil microbial community under high CO2 concentration and warming in the plots. To access the number of copies genes we used quantitative PCR, with the microbial community structure determined by T-RFLP and the microbial composition by Illumina next-generation sequencing. No-tillage and integrated crop-livestock revealed important capability to control N2O emissions. Notably, the high number of nosZ gene copies was found under no-tillage and integrated crop-livestock systems. This gene has a high potential to monitor the oxidation of N2O to N2. In addition, high CO2 concentration and elevated temperature increased 2-3 folds the number of copies of the nifH genes, and AOB nosZ throughout the experiment. The analysis of the diversity of functional taxonomic groups revealed that functional diversity has changed in plots with high N2O emissions, and showed a greater abundance of genes involved in denitrification, which possibly has stimulated the emissions of N2O from soil microbiota.

O objetivo deste trabalho foi comparar os cenários de inclusão e de não inclusão da delimitação da zona ripária da microbacia na determinação dos riscos ambientais, na adequação do uso do solo e conseqüentemente no planejamento sócio-ambiental, contribuindo com a elaboração e implementação dos planos de manejo integrado de microbacias com uso agrícola diversificado, considerando como premissas a busca da agricultura sustentável, a restauração do ecossistema ripário e o envolvimento social e econômico do produtor rural. Através de estudo de caso realizado na microbacia do Ribeirão São João (3.656 ha) no município de Mineiros do Tietê (SP), que faz parte do Programa Estadual de Microbacias Hidrográficas do Estado de São Paulo, foram feitas análises das suas condições sócio-ambientais que constaram de: a-) preparação de base cartográfica; b-) diagnóstico e planejamento participativos; c-) descrição de cenários convencionais e de cenários com inclusão da zona ripária para a adequação do uso do solo e caracterização dos riscos ambientais; d-) discussão sobre as relações entre o cenário que inclui a zona ripária e a legislação ambiental, a distribuição da estrutura fundiária, o uso e manejo agrícola e as estradas rurais e e-) proposta de um programa de monitoramento sócio-ambiental. O cenário com inclusão da zona ripária revelou que a microbacia possui 49,5 % de sua área com uso adequado, 20,4 % com sub utilização do solo e 1,9 % com sobre utilização. Quanto aos riscos de erosão, 60,2 % de sua área é considerada de baixo risco, 6,2 % possui moderado risco e 5,4 % compreende alto risco. Já o cenário convencional indicou que 59,0 % da área estão ocupados com uso adequado, 28,2 % com sub utilização, 2,6 % com sobre utilização, 76, 9 % da microbacia possui baixo risco de erosão, 11,0 % moderado e 12,1 % alto risco. Esta alteração induz o planejador a tomar medidas incompletas para a proteção das áreas que representam maiores riscos para a saúde da microbacia. Na microbacia estudada, 27,6 % da zona ripária está inserida em Área de Preservação Permanente, portanto protegida pelas leis ambientais, e 72,2 % estão sendo utilizados para agricultura, correndo risco de degradação. Em média, 26,1 % das áreas das propriedades rurais da microbacia se encontram em zona ripária. Parte destas poderia ser protegida pela Área de Preservação Permanente e pelo estabelecimento das reservas legais. A porção da zona ripária que não estiver protegida pela legislação ambiental deveria ter um manejo diferenciado de acordo com seu uso. Em vários pontos as estradas rurais atravessam os rios e a zona ripária podendo ocorrer danos ambientais se medidas corretas de adequação de estradas não forem tomadas. O cenário alternativo proposto corresponde também aos principais anseios da comunidade da microbacia, isto é, a preservação dos recursos hídricos, detectados através do diagnóstico e planejamento participativos. Levando em conta as condições da microbacia, assim como evidências baseadas na revisão de literatura, a proposta inclui o monitoramento sócio-ambiental, compreendendo o monitoramento da água, do solo, da integridade da paisagem, da biodiversidade agroambiental e dos aspectos socioeconômicos. / This work aims to compare the sceneries of including and not including the watershed riparian zone delimitation during the evaluation of the environmental risks in the land use planning, thus contributing for the implementation of integrated watershed management plans in the search of sustainable agriculture, based on the premises of riparian ecosystem restoration, as well as the direct participation of the land owners in the decision support process. A case study was developed in the São João creek Watershed, in the Municipality of Mineiros do Tiete, State of Sao Paulo. The case study included the preparation of the cartographic basis, diagnostic analysis and participative planning, description of conventional land use sceneries and alternative land use sceneries which include the delimitation of the watershed riparian zone, the comparison of the alternative sceneries in relation to the requirements of the Brazilian Forest Code in terms of stream buffer zone protection, as well as in relation to the watershed landownership structure , prevailing land use practices and rural roads design, and a proposition of an environmental monitoring program for the study watershed. The scenery that includes the riparian zone showed that 49,5% of the watershed total area has inadequate soil use, whereas 20,4% of the area with sub-utilization and 1,9% of the area with over-utilization. In terms of erosion risks, 60,2% of the watershed area can be considered with low erosion risk , 6,2% has moderate risk and 5,4% with high risk of soil erosion. The conventional scenery indicated that 59% of the watershed area has inadequate land use, 28,2% of the area is sub used, 2,6 % of the land is over used, 76,9% of the land has low risk of erosion, 11% has moderated soil erosion risk and 12,1% of the total area has high risk of soil erosion. Around 27,6% of the riparian zone are located in the Forest Code stream protection area, and 72,2 % of the area is prone to hydrological degradation due to inadequate land use practices. An average of 26,1% of the area of the watershed rural properties are located in the riparian zone. Part of this area should be protected according to the environmental law, or alternatively by the establishment of Legal Reserves. The portion of the riparian zone that is being used against the environmental law requirements should at least have a more conservative management approach. Rural roads cross the riparian zone in several locations and many of them cross the streams, which can pose hydrological risks. The proposed alternative scenery is in accordance with the main interests of the land owners, as detected in the participative planning, during which they raised concern about water resources conservation strategies. Considering the prevailing watershed conditions and also the information acquired in the literature survey, the study includes the monitoring of some water, soil, landscape integrity, biodiversity and socio-economic indicators.

Lack of sufficient water for irrigation is a major problem in and around the valleys surrounding the town of Aiquile, Cochabamba Bolivia. In addition, much of the region is undergoing desertification compounded by drought, deforestation, bad traditional agricultural practices, over grazing and a "torrential" rainfall pattern leading to severe soil erosion and low agricultural production. Between 1992 and 1994, the author constructed a network of 24 small, mostly rainfed farm ponds to increase agricultural production and alleviate soil erosion and land-use problems by improving cover conditions. A 5-year post-impoundment analysis was carried out in 1998. The analysis examined current pond conditions, design criteria, irrigation water / crop production increases and the alleviation of land-use problems. Current pond conditions fell into four distinct categories with only 25 percent of the ponds being deemed as "functioning well." The project increased irrigation in the region and improved cover conditions in 66 percent of the pond sites.
