Agriculture is central in Brazil's political and socioeconomic history; agricultural exploitation is mainly conducted by families, creating a type of agriculture developed in small rural properties named family farming. In Brazil, family farming accounts for a very diverse group of businesses, of which 91% of all the establishments are family establishments that build different production strategies according to different degrees of potentiality and precariousness. This study evaluated the role of rural credit policies in developing family farming activities with agricultural income generation in northeastern Brazil on various family-based farms. For this, the authors conducted a case study in Pernambuco, analyzing the spatial relationship between the distribution of family farms and the access to credit resources from the National Program to Strengthen Family Farming from 2006 to 2017 and the change probabilities in types of farms considering the next 10 years, given the maintenance of conditionsreported in the analyzed period. Results indicatedthe weakening of productive potentiality of farming activities in family farms in Pernambuco, with a significant change in the distribution of family farm types, a reduction in the participation of Specialized Farms and an expressive growth of Farms with Rural Residents. The findings also indicated the relevance of access to rural credit in the supply of production needs of different family farm types and development of farming activities with income generation.

Abstract: The concept of sustainability can be a way to understand the dynamics of reality and to consider not only the economic growth but also the social, environmental and cultural aspects of development. This new paradigm questions the role of nature as an instrument only to satisfy the human needs and brings into consideration the rational use of natural resources through responsible environmental policies keeping in mind the needs of the future generations. The economic growth, considered as the notion of progress, brings intrinsically not only the extensive nature exploitation but also the intensification of the energy use. Energy sources become, then, a strategic variable for the economic development. The Brazilian energy policy is an appropriate case study for the paradigm of sustainability overview as it is characterized by isolated initiatives and programs, which culminated into a huge crisis. So, this paper aims to discuss the concepts of sustainability and ethics through the analysis of the Brazilian energy policy and its social and environmental implications. [Copyright &y& Elsevier]
