No estudo em questão, objetivou-se analisar a construção discursiva presente na programação da Rádio Difusora do Paraná, no processo de modernização, especialização e diversidade agrícola no Extremo Oeste paranaense, mais especificamente no município de Marechal Cândido Rondon. O recorte temporal abrangeu o período de 1980-2000. A construção deste estudo foi norteada pela análise das fontes jornalísticas, não na condição de como a diversificação aconteceu, e acontece, e, sim, como uma instituição que se chama Rádio Difusora do Paraná, através de dois programas - Frente Ampla de Notícias (FAN) e Personalidade da Semana (PS), contribuiu na construção de discursos e representações referentes à agricultura. Para essa construção, participaram os atores (personalidades), através das quais surgiram conceitos, temas em torno do trabalho, agricultura, maquinário, clima, meio ambiente, cooperativismo e outros. Em suma, tratou-se de uma construção simbólica do agrário moderno. / The present study had the goal of analyzing the discursive construction present in the programming of Rádio Difusora do Paraná, in the process of modernization, specialization and agricultural diversification in the Far West of Paraná, more specifically in the municipal district of Marechal Cândido Rondon. The time frame ranged from 1980 to 2000. The construction of this study was guided by the analysis of the journalistic sources, not in the condition of how the diversification happened and happens, but how an institution that is called Rádio Difusora do Paraná, through two programs - Wide Front of News (FAN) and Personality of the Week (PS), contributed to the construction of speeches and representations referring to agriculture. The actors (personalities) participated in this construction, through which concepts, themes around the work, agriculture, machinery, weather, environment, cooperativism and others emerged. In short, it was a symbolic construction of the modern agrarian. / Orientador: Antônio Thomaz Júnior / Coorientador: Valdir Gregory / Banca: Jairo Gonçalves Melo / Banca: Marcos Aurélio Saquet / Banca: Eliane Tomiasi Paulino / Banca: Julio César Suzuki / Doutor

O século XVIII trouxe grandes mudanças na organização e administração da América Portuguesa. As capitanias ao sul do Brasil tiveram seus papeis redefinidos dentro do quadro de administração metropolitana e tornaram-se alvo principal das políticas econômicas portuguesas, que visavam desenvolvê-las e reorganizá-las. Nesse contexto, a Coroa buscou fomentar a diversificação dos gêneros agrícolas produzidos no Império Português, visando à integração maior entre as colônias e a própria metrópole. O estudo da capitania de São Paulo, a partir de 1765, permite que se compreenda a particular situação da região meridional do Brasil, onde constantes atritos com os espanhóis nas fronteiras exigiam a presença ostensiva de militares. A produção agrícola paulista, portanto, deveria orientar-se para a exportação a Portugal e para o abastecimento das tropas militares e da população civil. Esta pesquisa tem como hipótese a importância do papel da diversificação produtiva na reorganização da capitania de São Paulo, contribuindo tanto para a consolidação de relações econômicas internas quanto para a sua inserção mais efetiva no sistema colonial. / The eighteenth century brought new changes in the organization and administration of the Portuguese America. The captaincies located in the south of Estado do Brazil had their roles redefined within the Portuguese economic policies for their possessions in America, which aimed to develop and reorganize them. In this scenario, the Crown sought to foment the diversification of agricultural products, aiming for more integration between the colonies and the metropole. The study of the captaincy of São Paulo, after 1765, allows a better understanding of the particular situation of the south area of Brazil, where constant conflicts with the Spanish demanded the ostensive presence of military troops. The agricultural production of São Paulo had to be therefore oriented to exporting goods to Portugal and also supplying the local population (civil and military). The hypothesis of this research is the importance which the economical and agricultural diversification had over the process of consolidation of internal economic relations in São Paulo as well as its deeper insertion in the colonial system.

Sub-Saharan Africa is marginalised in the world economy and lags behind other developing regions in world trade. This is attributable to sub-Saharan Africa's inability to industrialise and diversify its exports base. Sub-Saharan Africa is still largely dependent on the exports of primary commodities, and agriculture is a vital export sector for many Sub-Saharan African economies with the majority of their exports reliant on traditional commodities. Most countries in the sub-Saharan African region have low levels of agricultural output and food security problems. Against this background, this study first discusses the problems associated with primary commodity dependence and then examines the need and economic rationale for sub-Saharan Africa to diversify its exports from agriculture into other sectors. From this, it follows that, diversifying agricultural production and exports into organic produce could be one way to create a more sustainable development path for sub-Saharan African trade and food security. With this in mind, this study discusses the economic viability, including the policy considerations, for organic product diversification in sub-Saharan Africa. In addition, to ascertain the empirical position of this study, a statistical assessment of the supply-side food security situation in three sub-Saharan African major organic converters and exporters (Kenya, Tanzania and Uganda) is presented. The empirical results indicate that among the three countries, considering data trends and variances, Uganda's food security outlook is the most optimistic. / Thesis (M.Com.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Agricultural biodiversity, commonly referred to as agrobiodiversity, is that part of biodiversity that is geared towards agriculture and food production. Agrobiodiversity is said to contribute much to food and nutrition, but there is lack of data confirming this, particularly from Eastern Africa. To assess the extent of agrobiodiversity on smallholder farms and in local markets and to connect these to food intake and perceptions of food security among smallholder farmers in Western Kenya, the thesis asks four main research questions: (i) What is the extent of food plant diversity in smallholder farms, the bio-physical and socio-economic factors influencing it and the contribution of this diversity to the household's food needs? (ii) What is the relationship between agricultural and dietary diversity? (iii) What linkages are there between agricultural and nutritional diversity? (iv) How does access to agrobiodiversity in local markets contribute to meeting household food needs and what is the extent of smallholder farmers' integration into these markets? Through a combination of focus group discussions, farm and market surveys conducted across three time points, results indicate that: (i) higher food plant species richness is found on farms managed by wealthier and older households. However, these households are not more food secure than the rest, (ii) while there is a lack of a strong relationship between agricultural and dietary diversity, dietary diversity is instead significantly influenced by socio-economic factors including a household's wealth status, ethnicity and education level, (iii) despite a diversity of locally available on-farm and market food species meeting existing macro-and micro-nutrient needs, there is a general lack of understanding of this diversity as food shortage months coincide with a lack of maize despite high availability of a diversity of other foods not only to replace the maize but also to contribute to a diverse diet, (iv) smallholder farmers rely on multiple food sources, with markets mainly for sourcing cereals, fruits and animal source foods. There is also low integration of smallholder farmers as sellers in local markets. Together, the four case studies show interlinkages across food availability, accessibility and utilisation, which when addressed with equal weight, could unlock local agrobiodiversity's potential as a path to food and nutrition security of smallholder farming households.

Thesis (M.A. Agricultural Science (Agricultural Economics)) -- University of Limpopo, 2019 / Livelihood diversification in South Africa has become the backbone for many of the households‟ in rural areas and it is perceived as a strategy to cope with the growing population and the rapidly increasing poverty rate. A sizeable number of rural households in South Africa work two or more jobs to generate more income. This serves as a strategy to alleviate their poverty. In spite of these, it is evident that poverty and high rate of unemployment are still prevalent in the rural Capricorn District. Thus, this study examined the nexus between poverty and diversification of livelihoods and to ascertain whether the different livelihood diversification strategies engaged in make rural households better-off or worse-off in the study area. A multistage and simple random sampling technique was employed to collect data from a sample of 216 respondents. Analytical techniques employed were descriptive statistics, FGT Poverty Index and the Probit Regression Model. Nine variables were included as explanatory variables in the Probit Regression and only six variables (gender of the respondents, marital status of the respondents, years of formal education, household size, livelihood index and member of association) were found to be significant at 10%, 5%, 1%, 10%,1% and 5%, respectively. Based on the findings, the study recommends that the diversification of livelihood strategies needs to be strengthened among rural households, investment in formal and vocational training should be intensified to increase rural households‟ participation in more viable livelihood options in the study area.
