Given the livelihoods challenges which face many rural communities, understanding a community’s livelihoods dynamics and opportunities is one major step to developing workable options to address the challenges. This study has focused on one rural community and used the five determinants of the Sustainable Livelihoods Approach to describe the livelihoods situation in Embui sub-location in Machakos County, Kenya. Residents of Embui have had to deal with the fact that traditional production systems are not sufficient to provide for their livelihoods needs. The community and continues to be challenged by limited capital for diversifying income sources, low skills and limited social and economic services. This study recommends support to marketing of locally produced artifacts, improved access to capital and provision of water for irrigation along with extension services as the key areas of support to improve the living standards of the residents of Embui / Development Studies / M.A. (Development Studies)

The study was done in Adaa district which is one of the 12 districts in East Shoa zone in Oromia regional state of Ethiopia. It is located southeast of Addis Ababa at 38o51’ 43.63’’ to 39o04’ 58.59’’ E and 8o46’ 16.20’’ to 8o59’ 16.38’’ N, on the western margin of the Great East African Rift Valley. The altitude ranges from 1 500 to ≥ 2 000 meters above sea level. The district has a high potential for mixed livestock and crop production systems. The purpose of this study was to make up for the paucity of information on livestock and environment interaction by assessing the relationship of livestock, soil, water, land, climate and crops under mixed crop-livestock production systems in central Ethiopian highlands. The objectives of the study were: (a) to assess the effect of change in land management on carbon storage and the contribution of livestock to carbon storage; (b) to examine the impact of livestock on natural resources and the environment; (c) to assess the effects of the change in traditional agricultural practices, expansion of factories, slaughter houses, greenhouses and flower farms on water and soil quality; (d) to evaluate the effect of climate change on livestock production under small-scale agriculture; and (e) to recommend options for mitigation and adaptation to environmental changes. The research design was non-experimental and did not involve the manipulation of the situation, circumstances or experiences of the interviewees. The design was comparative research that compared two or more groups on one or more variables, such as the effect of agricultural land use management, tillage type etc. on carbon storage in the soil. This research also applied a longitudinal design that examined variables such as the performance exhibited by groups over time. Purposive sampling was often used to measure the effect of agricultural, industrial effluent and human interferences on the environment by measuring nutrient contents at sources in the soil, water and manure. Biological data were complemented by key socio-economic survey by interviewing individual farmers and focus groups from sampling sites. Secondary data were also reviewed to measure soil degradation and run-off attributed to livestock. Results showed that animal waste and farmyard manure had the highest contribution in the addition of carbon in the soil. This implied that for most of carbon inputs livestock products and by-products had a greater place in the carbon sink. Therefore, livestock production could be considered as one of the major agricultural production systems in soil carbon storage. Similarly, livestock production systems also play an important role in maintaining the eco-system balance through nutrient recycling. On the average, the number of livestock per household for most species increased during the Derge regime in the 1990s compared to the Haile Sellassie regime in the 1970s when people did not own land; and then the number declined in the 2000s except for equines, crossbreeds and oxen. The change to crop intensification led to the change in the purpose for livestock keeping. Farmers started keeping certain types of animals for specific purposes unlike before when livestock was kept for prestige and economic security. The major drive for the change of attitude towards the purpose of keeping livestock was scarcity of resources, mainly feed and water. Equine ownership has significantly increased due to their low off-take rate and their feeding habits which allowed them to survive in harsh environments where feed resources were extremely scarce. There was a significant difference in crop response to manure application. Vegetables produced higher yields with manure than chemical fertilizers. Cereals on the other hand responded more to chemical fertilizers than to manure. Therefore, combining manure and chemical fertilizers was the best option for the sustainability of crop production in the study area. Some of the limitations to the use of manure as an organic fertilizer were inadequate manure production, high labour cost, bulkiness and high cost of transport to the fields and weed infestation. Manure management systems in the study area were affected by livestock husbandry practices. Only crossbred cattle (5%) were zero-grazed and used; and manure was stored in pits as slurry. Indigenous cattle were grazed outdoors in the fields during the day and at night they were kept in kraals near homesteads. There was a substantial loss of nutrients during the day when animals were grazing in the fields through leaching and trampling of dung and urine patches. Indoor or zero grazing of livestock could reduce nutrient losses. The use of manure as fuel in the study area had no significant effect on CO2 emissions at household or local level, but had a negative impact on soil organic carbon storage and soil fertility. Therefore, for improved yield and balanced eco-systems manure burning has to be replaced by other alternative energy sources such as bio-gas and kerosene. The largest carbon equivalent emissions were from CH4 (72.6%), N2O (24%) and CO2 (3.4%) which indicated the need to improve livestock and manure management systems under smallholder agriculture. Overall, there was an indication of a decline in water resources on per capita basis. The major contributing factors were combined pressure of human and animal population on natural resources that led to excessive deforestation, loss of biological diversity, overgrazing, soil degradation and various forms of pollution and contamination. The global climate change also played a role in the decline in water resources due to the decrease in annual precipitation and increasing temperatures. Urbanization and economic growth increased the demand for milk and meat, which required additional water use for each unit of increased animal protein. The demand for milk and meat is expected to double in the next 20 years with an annual growth rate of between 2.5 to 4%. From the sixty-year meteorological data (1951-2009) there was an established increase in rainfall by 2% per annum; and maximum and minimum temperature by 0.08oC per decade, which amounted to a cumulative temperature increase of 0.5oC in the last decade. The increase in precipitation and temperature favoured the adaption of lowland crops like maize and sorghum to highland agro-ecology. Climate prediction models forecasted that most of the highlands in Ethiopia will remain suitable for cereals like wheat and Teff for the next 50 to100 years. However, the perception of farmers indicated that they felt more heat and warm weather than they have experienced before. They reported that rainfall is now more erratic or comes late and stops earlier before plants completed their vegetative growth. / Environmental Sciences / D. Litt. et Phil. (Environmental Science)

Thesis(MPhil)--Stellenbosch University, 2014 / ENGLISH ABSTRACT: This thesis documents a Participatory Action Research (PAR) project conducted from 2011 to 2013 in a rural communal area in southern KwaZulu-Natal, South Africa. The area is a microcosm of the global environmental and socio-economic polycrisis; with adult unemployment at 50 percent, 73 percent female-headed households, heavy dependence on government social grants and a food system reliant on purchased food. Eight, mainly female-headed households (the co-researchers), assisted by the student researcher, implemented and assessed a cropping system, designed on agroecological principles, on their abandoned garden plots. The objective was to grow culturally acceptable food crops to supplement their household diets and positively affect their food security. The student researcher provided the necessary infrastructure, including goat-proof plot fences, hand tools, a grain hammermill, seed, and fertiliser. The literature review, which also used early 1900’s photographs and contemporary isiZulu language as evidence, revealed the agroecological basis of pre-colonial agriculture. However, colonial and apartheid influences destroyed this knowledge base. The cropping system design utilized practices from this pre-colonial era combined with current agroecological techniques. The agroecological techniques employed on the plots included non-inversion tillage of planting pits using garden forks, precision placement of phosphate fertiliser and animal manures, open pollinated seeds, east-west orientated strip cropping, soil surface mulches, crop rotations including legumes and the use of chickens to control pests. Dryland crops included maize, beans, sweet potatoes, and butternuts, with small trial vegetable patches on some plots. The research identified a method to calculate the planting frequency of these vegetables to ensure a constant annual supply, however further research is needed. The dryland crops supplemented household diets between harvests. The formation of structured groups amongst the households proved vital to the success of the cropping system, providing mutual labour assistance, shared decision-making, building knowledge and moral support. The importance of dialogue and trust, reinforced by the student researcher’s ability to communicate in isiZulu with the co-researchers, formed the basis of both the PAR, and Focus Group Discussions(FGD), used to qualitative assess the cropping system. During these, the households reported a good understanding of the agroecological principles of the cropping system, a willingness to continue with it post research, and positive benefits, including better health, and money saved on food purchases, redirected to improve their asset base. The World Food Programme (2008) Food Consumption Score Analysis Method (FCS), modified to show the percentage contribution of homegrown food to the FCS, provided the quantitative assessment of the cropping system. The FCS scores rose during the research, with homegrown food contributing over a third of the FCS at times. The co-researchers suggested instituting group ‘stokvels’1to finance inputs and maintain infrastructure post research. The financial implications of these ‘stokvels’ was calculated. Due to the initial success of the PAR, the research recommends a method to extend the cropping system to more households, utilizing state finance to provide the infrastructure, and the co-researchers imparting technical knowledge through farmer-to-farmer extension. / AFRIKAANSE OPSOMMING: In hierdie tesis word verslag gedoen van ’n deelnemende aksienavorsingsprojek wat van 2011 tot 2013 in ’n landelike dorpsgebied in die suide van KwaZulu-Natal, Suid-Afrika, uitgevoer is. Die gebied is ’n mikrokosmos van die wêreldwye omgewings- en sosio-ekonomiese polikrisis, met volwasse werkloosheid op 50%, 73% huishoudings met vroue aan die hoof, swaar afhanklikheid van die staat se maatskaplike toelae en ’n voedselstelsel wat van gekoopte kos afhanklik is. In die studie het agt huishoudings, wat hoofsaaklik vroue aan die hoof het (die medenavorsers), met behulp van die studentenavorser, ’n verbouingstelsel, wat op agro-ekologiese beginsels gegrond is, op hul verlate tuingrond geïmplementeer en geassesseer. Die doel was om kultureel aanvaarbare gewasse te verbou om hul huishoudelike dieet aan te vul en hul voedselsekerheid positief te beïnvloed. Die studentenavorser het die nodige infrastruktuur verskaf, met inbegrip van bokbestande omheining, handgereedskap, ’n graanhamermeul, saad en kunsmis. Die literatuurstudie, waarin foto’s uit die 1900’s en moderne Zoeloe as bewyse gebruik is, toon die agro-ekologiese grondslag van prekoloniale landbou. Koloniale en apartheidsinvloede het egter hierdie kennisbasis vernietig. Die verbouingstelselontwerp was gegrond op praktyke uit hierdie prekoloniale era gekombineer met moderne agro-ekologiese tegnieke. Hierdie tegnieke het ingesluit nie-inversie-grondbewerking van plantgate met gebruik van tuinvurke, presisieplasing van fosfaatkunsmis en dieremis, oop bestuifde sade, oos–wes-georiënteerde strookverbouing, grondoppervlak-deklae, wisselbou met onder andere peulgewasse en die gebruik van hoenders om peste te beheer. Droëland-gewasse het ingesluit mielies, bone, soetpatats en botterskorsies, met klein toetsgroenteakkers op sommige stukke grond. ’n Metode is in die navorsing geïdentifiseer om te bepaal hoe gereeld hierdie groente geplant moet word om ’n konstante jaarlikse voorraad te verseker. Verdere navorsing is egter nodig. Die droëland-gewasse het huishoudelike diëte tussen oeste aangevul. Die vorming van gestruktureerde groepe onder die huishoudings het noodsaaklik geblyk te wees vir die sukses van die verbouingstelsel, waardeur wedersydse hulp met arbeid, gedeelde besluitneming, die bou van kennis en morele ondersteuning gebied is. Die belangrikheid van dialoog en vertroue, wat versterk is deur die studentenavorser se vermoë om in Zoeloe met die medenavorsers te kommunikeer, het die grondslag gevorm van die deelnemende aksienavorsingsprojek asook die fokusgroeponderhoude, wat gebruik is om die verbouingstelsel kwalitatief te assesseer. In hierdie onderhoude het die huishoudings verslag gedoen van hul grondige begrip van die agro-ekologiese beginsels van die verbouingstelsel, hul gewilligheid om ná die navorsing daarmee voort te gaan, asook die voordele wat dit bied, soos beter gesondheid en geld wat op voedselaankope gespaar is, wat heraangewend is om hul batebasis te verbeter. Die Wêreldvoedingsprogram (2008) se Food Consumption Score- (FCS-)ontledingsmetode, wat aangepas is om die persentasie bydrae van selfgekweekte voedsel tot die FCS aan te toon, is gebruik vir die kwantitatiewe assessering van die verbouingstelsel. Die FCS-tellings het tydens die navorsing toegeneem, met selfgekweekte voedsel wat by tye tot meer as ’n derde tot die FCS bygedra het. Die medenavorsers het voorstel dat ’n stokvel gestig word om insette te finansier en die infrastruktuur ná die navorsing in stand te hou. Die finansiële implikasies van hierdie stokvel is bereken. Op grond van die aanvanklike sukses van die deelnemende aksienavorsingsprojek stel die navorser ’n metode voor om die verbouingstelsel na meer huishoudings uit te brei met behulp van staatsfinansiering om die infrastruktuur te verskaf asook die oordrag van die medenavorsers se tegniese kennis na ander boere.

Thesis (MPhil)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: The Tigray region in northern Ethiopia is a historic centre of agricultural production and home to many subsistence farmers that still use traditional farming systems and practise rain-fed agriculture. The region has been affected adversely by famines and periodic droughts for centuries and is vulnerable to climate change. Farmers are producing on small plots of often degraded land and through their own actions have depleted the natural resources they rely on, in particular soil, water and trees. This study sought to explore the environmental degradation of Tigray through both a literature review of its agricultural socio-political history and a lived experience in the village of Abraha We Atsebaha among farmers of the region. It uses a variety of methodologies and methods, including a literature review, grounded theory, narrative inquiry and ethnography, to expand on the factors that have contributed to the current degradation, the implications for traditional farming and the potential for land regeneration. The first journal article seeks to explore how Ethiopians have shaped their natural environment. In particular, it focuses on deforestation, soil degradation, the role of changing governance and land-ownership patterns, and the effects of climate change. The article demonstrates that traditional farming systems do not operate in isolation from their socio-political and environmental context. The second journal article provides an in-depth narrative inquiry conducted in Abraha We Atsebaha over a three-month period in 2014. This village is known for its indigenous farming knowledge, commitment to regeneration and innovation in conservation practices. Interviews were conducted with selected farmers and local leaders and informal discussions were carried out with government extension representatives using the ethno-ecological cosmos-corpus-praxis guidelines to enable an integrated exploration of the nature of traditional farming, the causative factors of environmental deterioration and the resultant communal response. In addition to written interview notes, observations and field notes were recorded daily. Photographs are used to give a real sense of the community and their work. It emerged during this process that underlying belief systems were exceptionally important in a context of traditional conservation. Both articles discuss the development work undertaken by government in the rural farming sector and the successes and challenges faced. They also show that elements of traditional farming, sustainability measures and environmental care were suspended in favour of short-term survival as a consequence of social, political and population stressors. This study provides learning points, gained from insights gleaned from the literature review and the lived experience, for improving development interventions in this region. This study did not explicitly explore the role of religion in conservation or the potential long-term effects of current government policies and initiatives. However, it contributes to the small pool of literature on the region focused on traditional farming systems by providing a comprehensive overview of the drivers of degradation (historical and current) and offers a unique, “soft” experiential narration of a village in northern Ethiopia that allows insight into farmer experiences, pressures and adaptation efforts. / AFRIKAANSE OPSOMMING: Die Tigray-streek in die noorde van Ethiopië is ’n historiese sentrum van landbouproduksie en die tuiste van menige bestaansboer wat nog op tradisionele boerderystelsels en reënbesproeiing staatmaak. Die streek het eeue lank onder hongersnood en periodieke droogtes gebuk gegaan en is kwesbaar vir klimaatsverandering. Boere bewerk klein stukke, dikwels afgetakelde, grond en het deur hul eie optrede die natuurlike hulpbronne waarop hulle staatmaak – veral die grond, water en bome – uitgeput. Hierdie studie was daarop toegespits om ’n beter begrip te vorm van die omgewingsaftakeling in Tigray. Vir hierdie doel is ’n literatuurstudie van die sosiopolitieke landbougeskiedenis van die gebied onderneem, en is die lewe in die dorp Abraha We Atsebaha tussen boere van die streek ervaar. Die navorsing het van ’n verskeidenheid metodologieë en metodes, waaronder ’n literatuuroorsig, gegronde teorie, narratiewe ondersoek en etnografie, gebruik gemaak om lig te werp op die faktore wat tot die huidige aftakeling bygedra het, die implikasies vir tradisionele boerdery, en die potensiaal vir grondvernuwing. Die eerste tydskrifartikel verken hoe Ethiopiërs hul natuurlike omgewing gevorm het. Dit konsentreer veral op ontbossing, grondaftakeling, die rol van veranderende staatsbestuurs- en grondbesitpatrone, en die uitwerking van klimaatsverandering. Die artikel toon dat tradisionele boerderystelsels nie afsonderlik van hul sosiopolitieke en omgewingskonteks funksioneer nie. Die tweede tydskrifartikel beskryf ’n narratiewe diepte-ondersoek wat oor ’n drie maande lange tydperk in 2014 in Abraha We Atsebaha onderneem is. Hierdie dorp is bekend vir sy inheemse landboukennis, toewyding aan vernuwing, en innoverende bewaringspraktyke. Onderhoude is met ’n uitgesoekte groep boere en plaaslike leiers gevoer, en voorligtingsbeamptes van die staat is by informele gesprekke betrek. Die etno-ekologiese cosmos-corpus-praxis-riglyne is gebruik om ’n geïntegreerde studie te onderneem van die aard van tradisionele boerdery, die oorsaaklike faktore van omgewingsaftakeling, en die gevolglike gemeenskapsreaksie. Benewens skriftelike aantekeninge gedurende die onderhoude, is waarnemings en veldnotas ook daagliks opgeteken. Foto’s word gebruik om die gemeenskap en hul werk getrou uit te beeld. Gedurende hierdie proses het aan die lig gekom dat onderliggende oortuigingstelsels besonder belangrik is in ’n tradisionele bewaringskonteks. Albei artikels bespreek die ontwikkelingswerk wat die regering in die landelike boerderysektor onderneem, sowel as die suksesse en uitdagings daarvan. Dit toon ook dat elemente van tradisionele boerdery, volhoubaarheidsmaatreëls en omgewingsorg as gevolg van maatskaplike, politieke en bevolkingsfaktore laat vaar is ten gunste van korttermynoorlewing. Die insigte wat uit die literatuuroorsig sowel as die lewenservaring in die bestudeerde gemeenskap spruit, bied lesse vir die verbetering van ontwikkelingsintervensies in die streek. Die studie het nie uitdruklik die rol van godsdiens in bewaring of die potensiële langtermynuitwerking van huidige staatsbeleide en -inisiatiewe ondersoek nie. Tog dra dit by tot die klein hoeveelheid beskikbare literatuur oor tradisionele boerderystelsels in die streek deur ’n omvattende oorsig te bied van die (historiese en huidige) snellers van aftakeling, en vertel dit ’n unieke, ‘sagte’ ervaringsverhaal oor ’n dorp in die noorde van Ethiopië om sodoende insig in landbou-ervarings, -druk en -aanpassingspogings te bied.

The aim of this study was to explore the role and the prospects of smallholder agriculture as local economic development in Eastern Pondoland, in the former Transkei homeland. The study explored the role of agriculture in contributing to local economic development and the upliftment of the rural poor. It also explored the role that government and its agencies have played and could play in stimulating agricultural development.

O consumo e o mercado de cafés especiais, como orgânicos, gourmets e socialmente justos, cresce no mundo todo oferecendo preços atraentes para o produtor, enquanto o mercado de cafés commodity encontra grande oferta e preços muito baixos. A produção orgânica revela-se como alternativa ambiental, social e econômica, pois não contamina o meio ambiente e nem as pessoas direta e indiretamente envolvidas, além de agregar mais valor ao produto final. Apesar de o Brasil ser o maior produtor mundial de café, com aproximadamente 45 milhões de sacas em 2002, a produção de café orgânico foi aproximadamente de 70 mil sacas, de acordo com a ACOB (Associação de Cafeicultura Orgânica do Brasil). O México é o maior produtor mundial de café orgânico, com aproximadamente 500 mil sacas em 2002, sendo a maioria proveniente de sistemas sombreados de café. A cafeicultura nacional caracteriza-se por extensas áreas de monocultivo a pleno sol, desconsiderando o fato do café ser uma espécie originária de florestas caducifólias da Etiópia. A produção de café orgânico brasileira também é, em sua maioria, a pleno sol, com pouca biodiversidade e grande input ao sistema. Países produtores de café orgânico em sistemas sombreados e consumidores criticam a ausência de biodiversidade do sistema brasileiro. Portanto, a pesquisa nacional deve avaliar cientificamente diferentes manejos de café orgânico, obtendo informações quantitativas e qualitativas, visando a sustentabilidade sócio-ambiental e ganho de competitividade internacional do produto brasileiro neste nicho de mercado. Na busca de parâmetros que permitam a caracterização do sistema sombreado e do sistema a pleno sol de café orgânico, a composição química elementar avaliada em elevado nível metrológico é uma ferramenta potencial. Esta alta confiabilidade metrológica pode ser obtida através da análise por ativação neutrônica instrumental (INAA). Para a caracterização destes sistemas de produção de café orgânico, vários elementos químicos foram quantificados por INAA em grãos e folhas de café Coffea arabica, variedade Mundo Novo, e nos solos de ambos os sistemas - café sombreado por árvore leguminosa Platycyamus regnellii e café a pleno sol, na fazenda Jacarandá, Machado, Minas Gerais. Foram também avaliados os parâmetros de produtividade, fertilidade do solo, nutrição vegetal e qualidade do café. Os resultados indicam uma perspectiva positiva para a discriminação dos dois sistemas de produção utilizando-se da composição química elementar determinada por INAA. As avaliações demonstram uma tendência à superioridade do sistema sombreado, principalmen te quanto às maiores concentrações de potássio encontrados em grãos, folhas e solo, que podem ter propiciado uma melhor qualidade do café deste sistema. / The consumption of special coffee, mainly organic coffee, is increasing worldwide following the tendency of consuming products socially fair and ecologically sustainable, providing new market opportunities for coffee farmers in developing countries. The organic coffee is considered to have a better quality, once no agrochemicals are used and therefore, only the essential elements of the coffee will be present in the final product. Brazil is the largest world coffee producer, with 2,700,000 tons of green coffee in the 2002 harvest. However, only 4,200 tons are certified organic coffee, according to the Organic Coffee Brazilian Association (ACOB). The cultivation of organic coffee and shaded coffee are common in Central America, while in Brazil both conventional and organic coffee are mainly cultivated in the full sun system. Mexico, the largest world organic coffee producer, harvested 24,000 tons of certified organic coffee in the 2001-2002 season, most of it from shaded organic coffee system. In Brazil, such system is not well trusted and is also known as less productive. The full sun organic system is very criticized because of the lack of biodiversity and the high demand for external organic fertilizers. The shaded coffee system recycles more nutrients and has biodiversity, consequently, less dependent on external organic fertilizers, insecticides and fungicides. To characterize these two distinct organic coffee production systems, several inorganic chemical elements were quantified by instrumental neutron activation analysis (INAA) in coffee beans and leaves from Coffea arabica, variety Mundo Novo, leguminous shade tree (Platycyamus regnellii) leaves and soil from both systems at the Jacarandá farm, Machado, Minas Gerais State, Brazil. Other parameters such as productivity, soil fertility, plant nutrition and coffee quality were also evaluated. Results show a positive perspective for discrimination of the two production systems, through the chemical composition by INAA. The evaluations show a tendency of superiority for the shaded treatment, mainly according to the higher mass fractions of K in grains, leaves and soil, which may have caused better coffee quality.

This study explores issues arising from the adoption of the term 'clean and green' for marketing New Zealand dairy products. Three dimensions of environmental quality were investigated: that of sustainable dairying and best practice for the benefit of farmers and the industry; resource management legislation and being a 'good neighbour'; and export marketing opportunities and issues. The study was undertaken during a time of major structural upheaval in the dairy industry, including yearly company amalgamations in the study area, rapid conversion of farmland to dairying, as well as factory expansion to process the increasing supply of product. The focus of the study was on the individual farmer, how perceptions and preferences are formed, and how in turn, these influence farm practice. World views drawn from Cultural Theory were adopted as the basis for analysis. Farmers were classified according to particular world views and the symbolic and reflexive use of concepts such as 'clean and green' was analysed. A model of overlapping ecological, agricultural and social systems was used to develop a wider understanding of preference formation. Through a mixed methodology, focusing on a case study approach, farmer and stakeholder world views were compared on key themes, including the 'clean green' pastoral myth, 'cues for care' and environmental issues. Media discourse as well as consumer views were used to expand understanding of the context. The study found that both farmers (within their groups) and stakeholders held different objectives and opinions on environmental issues and options for change, based on their various world views and preferences. There was general agreement both among farmers and stakeholders on the New Zealand 'clean green' image and 'cues for care', or signs that indicate good farm management. The reason for this was demonstrated to be the way in which these two aspects are communicated; through symbolic images that each individual perceived in terms of their respective world view. A symbolic form of action, an environmental management system, was trialled with farmers. Analysis indicated that national aspirations created by the 'clean green' pastoral myth required farmers to respond to environmental expectations, but that an image that symbolized environment as care and quality, rather than as place was needed to provide a less ambiguous goal. The findings of the trial were integrated with theory to interpret context and develop policy, strategy and action proposals for a system for environmental quality for the industry. The study has implications for non-regulatory mechanisms relevant to sustainable dairy farming, communication within the rural community, and branding.

This study investigated the local and sustainable food movements in the Willamette Valley of Oregon. The aim of the research was to better understand the current condition of the phenomenon, what it means to the communities studied and the future role it will play in the state. Other research objectives that were studied included the impact of demographics on food movements, successes and barriers to success and determining the motivations of people involved. Key players in the city of Corvallis and Portland were interviewed to gather qualitative data about the movement. Interviewees were chosen based on criteria established through literature review that pointed towards groups that would be the most valuable on which to focus. The study revealed a dynamic and progressive social movement that has profound and beneficial implications on the civic wellbeing of the communities studied both currently and for their future. In addition, through this work key goals were identified that can be transferred to other communities looking to work towards a more sustainable food system in order to better facilitate their growth and prosperity. / Graduation date: 2013

Herbicides have become a key component in modern agricultural production. Meanwhile, there is a concern that some herbicides persist past the growing season of the treated crop, and negatively influence the production of the subsequently planted crops. Amongst various herbicides used in western Canada, acetohydroxyacid synthase (AHAS)-inhibiting herbicides warrant special attention given their residual properties and acute plant toxicity at low concentrations in soil. Soil residual AHAS inhibitors have the potential to influence both leguminous host plants and their bacterial symbiotic partners; consequently, the use of an AHAS inhibitor in a given year can negatively influence the inoculation success and grain yield of legumes cropped in the following year. <p>The present thesis project focused on one of the AHAS inhibiting herbicides (flucarbazone) and studied its potential for carryover injury and negative influence on the success of inoculation in field pea. A series of growth chamber and field experiments were conducted to test the following null hypothesis: the presence of residual flucarbazone in soil does not affect nodulation of field pea by inoculum rhizobia. <p>A growth chamber experiment clearly demonstrated the susceptibility of field pea to the presence of flucarbazone in soil where the lowest concentration of flucarbazone amendment (5 ìg kg1) significantly reduced the crop growth. In contrast, a field study failed to reveal any negative effects of flucarbazone use on crop growth and N2 fixation. <p>It was concluded that if the weather and soil conditions favour decomposition of flucarbazone as described in the present study, flucarbazone applied at the recommended field rate will not persist into the following season at high enough concentrations to negatively influence field pea growth, grain yields, and inoculation success. To ensure safety of rotational crops, it is important to strictly adhere to the herbicide application guidelines. Additionally, producers are cautioned to be particularly aware of the environmental and soil conditions that may reduce the rate of herbicide degradation.
