O impacto da certificação foi o tema central desse projeto de pesquisa que consistiu em identificar o seu efeito sobre variáveis de interesse, isolado de outras fontes de variação. Para isso, uma metodologia de avaliação de impacto foi adaptada e testada para analisar a Certificação Socioambiental Rainforest Alliance da Rede de Agricultura Sustentável RAS na cafeicultura em Minas Gerais. A Certificação Socioambiental cresceu significativamente em fazendas produtoras de café no Brasil e no mundo desde sua criação em 1998 até o ano 2007. Os produtos vendidos com essa certificação carregam consigo a mensagem que vêm de sistemas de produção que promovem mais desenvolvimento humano e mais conservação da biodiversidade quando comparados aos sistemas convencionais. Contudo, o processo de Certificação Socioambiental não mede diretamente essas diferenças. Na rotina da certificação, o auditor avalia a conformidade dos sistemas de produção a padrões pré-estabelecidos. A ausência de avaliações de impactos pode acarretar questionamentos referentes às reais transformações decorrentes da certificação. Outro questionamento refere-se à elaboração das normas, as quais foram formuladas em processos de consulta pública com as partes interessadas, as quais estabelecem uma referência do que é desejável segundo a percepção de cada participante. Esses atores, num determinado momento ou contexto, podem ter dado maior ênfase a alguns aspectos que outros e não explicitam quais os problemas dos sistemas de produção conve ncional que pretendiam superar. Além disso, podem ocorrer mudanças de conduta e paradigmas nos sistemas convencionais que podem afetar no tempo as decisões das consultas públicas. Como parte do objetivo desse projeto pretendeu-se obter uma referência de sistemas de produção com e sem certificação como subsídio para elaboração das normas de certificação e para orientação dos trabalhos dos auditores. O método de avaliação de impacto utilizado foi comparar os empreendimentos agrícolas certificadas com os nãocertificados de forma a obter o cenário contrafactual, isto é, qual seria a situação dos empreendimentos certificados se, hipoteticamente, não tivessem passado pelo processo de certificação. A amostra foi de seis empreendimentos agrícolas do Sul de Minas e dez do Cerrado Mineiro, um total de 444 trabalhadores entrevistados. Os resultados foram gerados por meio da análise quantitativa dos dados primários obtidos por meio de entrevistas com os trabalhadores e com a administração da fazenda, análise de imagens de satélite e observações de campo. Os três temas selecionados para testar a metodologia foram bem estar dos trabalhadores, preservação da biodiversidade e conservação dos recursos hídricos e redução da poluição. Os resultados afirmaram a importância da Certificação Socioambiental para promoção da conservação da biodiversidade e do desenvolvimento humano no curto e longo prazo. Porém, não foram identificados impactos em alguns aspectos analisados, bem como uma manifestação distinta dos impactos nas regiões. A metodologia mostrou-se apropriada para identificar os impactos da certificação e para definir uma referência que contribua substancialmente para construção das normas e para orientar o trabalho de auditoria de forma a acentuar a contribuição da Certificação Socioambiental para promover a conservação da biodiversidade e o desenvolvimento humano. / The impact of certification was this research project´s major focus, which consisted of the identification of the effect of certification over interest variables, isolated from other sources of variation. Specifically in this dissertation, an impact assessment methodology was adapted and tested to analyze the impact of Rainforest Alliance socioenvironmental certification scheme, utilized by the Sustainable Agriculture Network - SAN (in Portuguese, RAS), in coffee plantations located in Minas Gerais State, Brazil. Socio-environmental certification has increased significantly in coffee-producing farms in Brazil, as well as worldwide, since its creation in 1998 up to 2007. Commercialized products with this type of certification carry a message that they are rooted in production systems which promote greater human development and biodiversity conservation values when compared to conventional systems. However, the socio-environmental certification process does not currently measure these differences in a direct way. During certification procedures, an auditor assesses whether production systems are accomplishing pre-established standards. The absence of impact assessments might raise doubts regarding real transformations provoked by certification. Another doubt relates to the establishment of such standards, which were elaborated in public meetings among interested parties that established a reference about what is desirable according to each participants perception. These stakeholders, in a given moment or context, may have emphasized some particular aspects without clarifying which of the problems of the conventional systems they intended to solve. Moreover, changes might occur in the conduct or paradigms of conventional systems which can affect decisions made in public meetings. As part of this projects objective, it was intended to obtain a reference for production systems with and without certification, to subsidize the establishment of standards and to guide auditing procedures. The impact assessment method utilized was based on comparing certified and non-certified agricultural enterprises in such a way as to obtain a non-factual scenario, in other words, what would occur in the certified enterprises if, hypothetically, they had not been targeted by certification. The sample consisted of sixteen agricultural enterprises in Brazil. Results were generated through quantitative analyses of primary data gathered through interviews with farm workers and managers, satellite image analyses, and field observations. There technical issues selected to test the methodology were worker welfare, biodiversity preservation and water resource conservation, and pollution impact. Results indicate an important role of Socio-environmental Certification in promoting conservation of biodiversity and human development in the short and long run. Some analyzed aspects did not present impacts, however, and some impacts presented a differentiated response in different regions. The methodology used was concluded to be suitable for identifying certification impacts and for defining a reference to substantially contribute to building standards, as well as guide auditors´ work in such a way as to increase the contribution of socio-environmental certification to biodiversity conservation and human development.

This thesis discusses the detrimental effects that industrialized farming practices have on public health, animal welfare, and ecological systems and includes factual support. It also provides practical application of this information as well as possible solutions and a detailed description of a related art exhibition.

While Portland, Oregon's sustainable food movement wins accolades for explicitly situating itself in opposition to the industrialized global food system, it often fails to address systems of oppression that are reproduced within the alternative agri-food movement itself. This demonstrated aversion towards the messy, complex, contingent nature of the social world reflects larger processes of "de-politicization" of the overall sustainability agenda, which leads to the favoring of technological and/or spatial solutions that may undermine the social equity and justice dimensions of the "triple bottom line." This thesis focuses on an action research project involving a series of community dialogues that provided participants with a common language and understanding necessary to interrogate issues of race and class in Portland's sustainable food movement while developing visions for possible futures. Dialogue participants may find new ways to communicate, learn, identify common goals and best practices, and potentially network, collaborate and/or co-produce transformative anti-oppression strategies that integrate into the sustainable food movement. By asking those vested in the sustainable food movement to interrogate dimensions of anti-oppression consciousness, the movement becomes fortified with voices better equipped to envision sustainability within a more political and contingent reality that recognizes conflicts of power, and less resembling an idyllic, utopian, and ultimately impossible sustainability. This thesis delivers some preliminary outcomes following the dialogue series by describing and reflecting on the series' implementation and processes, and reflecting on its impact on participants' anti-oppression consciousness in the context of food and sustainability, while discussing possibilities for future scholarship.

Seeds have become one of the most contested resources in our society. Control over seeds has intensified under neoliberalism, and today four large multinational corporations control approximately 70 percent of the global seed market. In response to this concentration of corporate power, an international social movement has emerged around the concept of seed sovereignty, which reclaims seeds and biodiversity as commons and public goods. This study examines the relationship between the global dynamics of commodification and enclosure of seeds, and the seed sovereignty countermovement for decommodification. I approach this analysis through an ethnographic case study of one local seed sovereignty movement, in the indigenous central region of Chiapas, in southern Mexico. I spent eight months between 2015 and 2016 conducting field research and documenting the development of the Guardians of Mother Earth and Seeds project, a local initiative focused on seed and food sovereignty that was initiated in 2015 by DESMI, the most established NGO working in this region. It encompasses 25 peasant communities--22 indigenous and 3 mestizo--from the Los Altos, Norte-Tulijá, and Los Llanos regions of Chiapas. I also collected data from 31 other communities in the region involved to varying degrees with this agenda of seed and food sovereignty. This study incorporates both communities affiliated with the Zapatista Army of National Liberation (EZLN) and non-Zapatista communities. Three research questions guide this dissertation: (1) How do the increasing industrialization and commodification of seed systems and agriculture affect peasant communities in Chiapas?; (2) How is the local seed and food sovereignty countermovement responding to those processes of commodification?; and (3) How does this case study contribute to understanding the relationship between capital's tendency to enclose the commons and the protective countermovements that attempt to resist such market encroachments? This study found that the development of industrial agriculture and the commodification of seeds at the global and national scales have implied neither the displacement of these communities' native seeds by commercial seeds, nor their privatization--two of the most frequent potential risks denounced by representatives of the national and international seed sovereignty movement. Instead, the main impact of industrial agriculture and Green Revolution policies in the study region has been the chemicalization of peasant agriculture, with attendant negative impacts on the environment and human health. I also found that subsistence agriculture--the main mechanism through which native seeds are reproduced within communities--is undergoing a process of severe deterioration, which partially responds to the neoliberal dismantling of governmental institutions and programs supporting peasant agriculture. A key finding of this research is that the deterioration of subsistence agriculture is the main risk that the neoliberal restructuring of agriculture poses to native seeds. In response to these developments, communities in this study have embraced a project of decommodification focused on enhancing and expanding their subsistence agriculture. This project encompasses agroecology, food production collectives, and initiatives for agro-biodiversity conservation and ecological restoration. I argue that this project contributes to the decommodification of subsistence agriculture in the region, primarily by strengthening the non-commodified structures that are essential for these communities social reproduction.

This thesis focuses on the idea that food insecurity and access are real issues in the lives of many Americans. Simply stated, food insecurity is when a person does not have enough food to eat or does now know where his/her next meal is coming from. More importantly when looking at food insecurity is the realization that healthy, local food access is even more prevalent an issue – with increasingly more under-resourced individuals and families being food insecure and unhealthy at the same time. This thesis includes a literature review on diet and nutrition in the United States, a chapter on methodology, history of Bowling Green, Kentucky, where this case study is focused, the benefits of shopping at farmers’ markets, perceived barriers to shopping at those farmers’ markets, and suggestions for overcoming these barriers. Local, sustainable food is the hope for a future of planet earth. It is what nourishes and sustains lives. And, it should not be a privilege. Through researching the benefits and barriers to farmers’ markets, examining these barriers, developing suggestions for overcoming these barriers, and implementing as many as these initiatives as possible in Bowling Green, Kentucky, I have not only compiled a detailed thesis, but I have also been a small part of creating change in the food community in Bowling Green. This thesis can serve as a nationwide model and describes the way to overcome food accessbarriers in urban/rural communities.

Thesis (MTech. degree in Architecture: Professional)--Tshwane University of Technology, 2008. / The aim of this dissertation is to design an urban-agricultural building to facilitate small scale intensive farming on the edge of the city of Durban. The buildings assume the typology of a vertical farm which has been named the 'ZED' farm, 'ZED' being dichotomous. Firstly the term has been borrowed from Bill Dunster Architects who coined the acronym 'ZED' (Zero Energy Development), which is one of the project's inherent objectives. The second meaning of 'ZED' is a translation of the building's main programmatic function of production in the vertical Z-axis. The site is located on the interface of the metropolitan edge, in an area bustling with activity ranging from industry, trade, recreation, public transportation, and a residential component. This area is flanked by the Umgeni Road corridor and the Suncoast Casino lifestyle entertainment centre along the beachfront.

This descriptive, phenomenological case study presents the perspectives of small-scale coffee producers in Guatemala regarding cooperative membership, sustainable coffee certification programs and the role of ANACAFE. The viewpoints of two producer cooperatives are described based on participant observation, semi-structured interviews and focus groups. Through content analysis the transcribed data were categorized and summarized, and emergent themes are discussed. Advantages to cooperative membership include access to finances, information, cost sharing and expanding direct-trade relationships. Challenges identified are securing finances and attracting new membership. Certification programs may be desirable, but access to information regarding program types is limited. Participants feel that standards do not reflect cultural differences, and the producers question who actually receives the advertised price premiums. The use of best-practices incorporating the social, environmental and economic principles of certification programs is preferred. ANACAFE is a source of technical information and funding but resource access is selective and limited.

Maize production plays an important socio-economic role in rural communities of the Highveld region of South Africa, yet it is becoming increasingly difficult to produce maize economically with current agricultural policy conditions and existing management systems. This has direct socio-economic impacts for both commercial farmer and small-scale farmer. Sustainable commercial maize production is not only a question of yields, but also of protection of the environmental resource base, social welfare, and the livelihoods of farmers per se as well as the surrounding rural and urban communities. Sustainability for the small-scale farmer, on the other hand raises questions of equity, economic viability and household food security. Therefore, information is required to ascertain whether an existing agro-ecosystem can be identified as sustainable, and what facets of that system make it sustainable or unsustainable. To begin to answer these key questions it is important to state, and to some extent attempt to standardise, the definitions of agricultural sustainability. Agro-ecosystem sustainability with regard to maize production was assessed at the regional scale of the Highveld of South Africa as well as at, the Quaternary Catchment scale and the smallholder farm scale. Von Wiren-Lehr's (2001) goal orientated system was considered an appropriate and practical system by which agro-ecosystem sustainability across a range of scales could be investigated. At the regional scale, optimum management strategies for each of the 497 Quaternary Catchments in the Highveld region were devised, based on present climatic conditions and using an index which was based on mean yields and yield variability. Economic returns and their impact on sustainability were then also assessed under plausible future climate scenarios. At the Quaternary Catchment scales optimum management strategies were ascertained by using a sustainability index. These strategies were then modelled under present and plausible future climate scenarios. The results from the sustainability modelling showed that a maize crop will benefit, especially with respect to mean grain yields, from an effective doubling of atmospheric CO2 concentrations. However, this benefit can be counteracted when there is a concurrent increase in temperature, particularly of 2°C or more. At the smallholder scale, a range of management options was assessed. These options included several types of tillage practices in combination with applications of either inorganic fertiliser or manure. The management strategies were modelled under present climate conditions and under plausible climate change scenarios for southern Africa. The conventional tillage type (disc) was ranked highest under most of the climatic conditions modelled, including present climate conditions. This was in contrast to actual yields from smallholder farmers (-1 ha field size) in the Potshini area, near Bergville in the KwaZuluNatal province of South Africa, who have experienced an increase in yield when conservation tillage practices have been used on their land (Smith et al., 2004). The sustainability of agro-ecosystems depends on the maintenance of the economic, biophysical and social components that make up the system (Belcher et al., 2004). The modelling performed for the Highveld region built on previous work and for the first time incorporated daily temperatures and ISCW soil information into CERES-Maize. The intention was to incorporate other agro-ecosystem functions, as well as yield, into the sustainability assessment. Only limited research has previously been carried out in South Africa with respect to modelling smallholder agro-ecosystems and sustainability. This research sought to model the smallholder system along with the impacts that climate change would have on sustainability and associated food security. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

The present context of community based natural resource management is characterized by multiple stakeholder involvement, a situation that presents challenges in aligning vision for common action. A 'systemic intervention' involved the staff and stakeholders of the Farmer Support Group, a non-profit rural development organization based in KwaZulu-Natal, South Africa. The 'creative design of methods' guided inquiry in aligning vision of a Landcare ethos amongst the organization and their stakeholders, and in directing action toward the vision. Critical Systems Thinking is outlined as the framework in which the intervention methodology is encompassed. The importance of applying a broad range of environmental education methods to Landcare is established through drawing from present debates and contexts in environmental education and community based natural resource management. The 'organization as community' approach to organizational learning and development is highlighted as a means of creating synergy of purpose across staff and stakeholder boundaries. The intervention's methodology consisted of three phases: drawing out perspectives, forming a common vision in a mission statement, and developing action plans based on the mission statement. Outcomes included: identification of three schools of thought that drove perspectives on the role of environmental education in natural resource management strategies, formation of the FSG Landcare Ethos Mission Statement, which was inclusive of all stakeholder perspectives, and integration of the mission statement into FSG projects through action plans. The intervention found that aligning staff members and stakeholders in common vision and action towards developing a Landcare ethos could be accomplished through a blend of environmental education approaches that facilitate sustainable decision making by building capacity in individuals and communities in a participatory and locally relevant manner that is attentive to predominant perspectives and adaptive to change. / Thesis (M.Agric.)-University of Natal, Pietermaritzburg, 2004.
