PRONAF dez anos depois: resultados e perspectivas para o desenvolvimento rural

Este artigo tenta efetuar uma avaliação da eficiência e eficácia do PRONAF (Programa de Fortalecimento da Agricultura Familiar) em gerar renda e melhoria de condições de vida para os agricultores familiares nos últimos dez anos da seguinte forma: comparam-se para isto as liberações de crédito com o custo das mesmas para o Tesouro (abrangência versus custo), estuda-se a focalização do PRONAF e resumem-se 13 avaliações realizadas ao longo destes 10 anos por diversas instituições acadêmicas e por autores de diferente extração ideológica.<br>The main goal of this article is to evaluate efficiency and efficacy of PRONAF (Program for the Strengthening of Family Farming) with respect to income generation and melioration of quality of life in the last ten years in the following matter: Comparison credit allowances with treasury costs, analyzing focalization of PRONAF and resuming 13 evaluations made during last ten years by authors of different ideological and academic backgrounds

Development and application of a bioeconomic efficiency index for beef cattle production in Rio Grande do Sul, Brazil

An index was developed to estimate the bioeconomic efficiency of production systems, identifying alternative scenarios that could improve their efficiency, and building isoefficiency relations in beef cattle production systems in Rio Grande do Sul. The concept of return on investment was used to develop the indicator. Scenarios regarded as efficient showed values higher than 3. The bioeconomic efficiency index for beef cattle production in the theoretical reference scenario was considered inefficient. At least four modifications in the variables method made it a bioeconomically efficient activity. These circumstances were studied using sensitivity analyses, with theoretical changes in the scenarios by changing variables two by two, while the others were kept constant. In Rio Grande do Sul, alternatives that make the activity efficient were identified by changing productivity, production cost, land price and product price. Isoefficiency relationships were identified in other scenarios. The application of this indicator in other agricultural activities, as well as the design of bioefficiency studies including both environmental and social welfare characteristics are recommended
