Um dos principais objetivos do Programa Nacional de Produção e Uso do Biodiesel (PNPB) tem sido desenvolver aagricultura familiar, através de incentivos fiscais às usinas produtoras de biodiesel que adquirem matérias-primas desse segmento. Este trabalho faz um breve levantamento das principais discussões em torno dos resultados sociais que o programa vem apresentando e conclui que mesmo o Estado mobilizando diversos agentes para atuarem em favor do eixo social, não há consenso em relação aos ganhos efetivos do programa no tocante a esse aspecto, tampouco desenvolvimento das regiões Norte e Nordeste como resultadoda implantação da política de biodiesel.Palavras-chave: PNPB, biodiesel, eixo social, agricultura familiar.NATIONAL PROGRAM OF BIODIESEL PRODUCTION AND USE: divergences on the social results of the biodiesel policyAbstract: One of the major objectives of the National Program of Biodiesel Production and Use has been the development of the family farm, through tax incentives for the biodiesel producers, which acquire raw material from this segment. This paper makes a survey of the main debates about the social results that have been presented by the program, concluding that even the State using their means in favor of the social side, there is no consensus on the program achievements at this point, nor the development of the North and Northeast regions as a result of the biodiesel policy.Key words: PNPB, biodiesel, social axis, family farming.

As Earth’s fossil energy resources are limited, there is a growing need for renewable resources such as biodiesel. That is the reason why the social, economic and environmental impacts of biofuels became an important research topic in the last decade. Depleted stocks of crude oil and the significant level of environmental pollution encourage researchers and professionals to seek and find solutions. The study aims to analyze the economic and sustainability issues of biodiesel production by a systematic literature review. During this process, 53 relevant studies were analyzed out of 13,069 identified articles. Every study agrees that there are several concerns about the first-generation technology; however, further generations cannot be price-competitive at this moment due to the immature technology and high production costs. However, there are promising alternatives, such as wastewater-based microalgae with up to 70% oil content, fat, oils and grease (FOG), when production cost is below 799 USD/gallon, and municipal solid waste-volatile fatty acids technology, where the raw material is free. Proper management of the co-products (mainly glycerol) is essential, especially at the currently low petroleum prices (0.29 USD/L), which can only be handled by the biorefineries. Sustainability is sometimes translated as cost efficiency, but the complex interpretation is becoming more common. Common elements of sustainability are environmental and social, as well as economic, issues.


Many small farmers charged that Ezra Taft Benson’s farm policies were driving them out of business. The fact that the countryside was hemorrhaging population during the 1950s seemed to support their contention. Indeed, the largest wave of farm abandonment and out-migration in the nation’s history occurred in those years. This chapter explores Benson’s agrarian polices while he was the secretary of agriculture in the Eisenhower administration. In specific, this chapter explores the following questions: What did he say over the course of his career about the moral and spiritual values and the economic costs of family farming? How did he respond to criticism of his policies by small farmers? How did he justify his policies and what advice did he offer? Did he regard the exodus of Americans from small farms as lamentable but inevitable? To what degree did he recommend educational opportunities or rural development policies to ease the transition from farm employment to non-farm work and urban lifestyles?

Several raw materials have been used in the biodiesel production since the implementation of the National Program of Production and Use of Biodiesel through the Brazilian Law 11.097 of January 13th 2005. The most common way used to produce this biofuel is the transesterification reaction which, among others features, requires a raw material with low acidity level. When this condition is not reached, the esterification reaction is alternatively used to convert free fatty acids into mono alkyl esters. Sulfuric acid is one of the catalysts that can be used in the esterification reaction which, therefore, can react with the alcohol generating dimethylsulfate. The aim of this technical report is to discuss the chemical reactions involved when the esterification reaction is used and the effects that this may cause, such as exposure to carcinogenic products.

Abstract This work evaluated whether the main goals established by the National Program for the Production and Use of Biodiesel (PNPB) were achieved between 2004 and 2018. For this purpose, reports and surveys prepared by public agencies and soybean producers were used. The results reveal that expectations of improvement in living conditions in rural areas stemming from PNPB implementation were frustrated: there were job losses in agricultural occupations, continuity of rural exodus, increase in land concentration, reduction in the contingent of family farmers, non-inclusion of poor family farmers from the North and Northeast regions. Of the original PNPB goals, only the minimum percentage of biodiesel to diesel was achieved satisfactorily, but dependence on imported diesel increased, even with the development of biodiesel production.

The survival of family farms is threatened by rapid change, intense international competition, and a resulting reduction of interest in perpetuating the family farm. What influences the next generation to pursue family farming, in spite of the difficulties? Do these factors differ between men and women? An in-depth, descriptive, and exploratory study of thirty next generation family farm members indicates specific factors critical to their decision to pursue the family farm succession. The findings are depicted in a framework that portrays these factors of influence and the effect they have on the succession decision of the next generation. Implications for practice and future research are also presented.

For the first time, perennial materials on the Orchidacaeae Juss. family of Chechnya are summarizedб consisting of 15 families and 29 species. The largest genus in the family – Orchis L. is represented by 8 species. The article presents information that all members of the family are protected plants listed in the Red Book of Chechnya, Ingushetia, Dagestan, and the Stavropol Territory. Some species are not included in the list of plants to be protected, including those species that have underground tuberoids and can serve as a source of salep (for instance, Platanthera bifolia, P. chlorantha, Herminium monorchis, Traunsteinera sphaerica, Dactylorhisa incarnata, D. salina, D. urvilleana). In this connection, data on the resources of family members and the potential possibilities of their use as a medicinal raw material are of interest. We have carried out resource studies of the most common species of Orchis tridentata Scop, within the North Caucasus. The obtained data allow us to expand our understanding of the species role of Orchidaceae Juss family.

This paper is divided into three sections. The first section describes the historiographic evolution of the study of prehistoric lithic raw materials in the Basque Crossroads (in the north of the Iberian Peninsula) during the last three decades. The second section explains the currently available information about geological outcrops of flint in the eastern end of the Cantabrian Mountain range (the Basque-Cantabrian Basin), the upper Ebro valley and both sides of the western Pyrenees, in the central part of the northern Iberian Peninsula, as that was the main raw material used by hunter-gatherer groups in the Middle and Upper Palaeolithic. Finally, the last section describes the way in which progress in both aspects of research have enabled the introduction of new concepts and perspectives in the reconstruction of the social and economic dynamics of Palaeolithic hunter-gatherers. This has given rise to an innovative methodology that is able to address and solve important issues, particularly regarding mobility and territoriality patterns of those human groups, allowing the proposal of mobility and territoriality models that, while they will not match exactly the systems used by Upper Palaeolithic communities, represent significant progress in understanding the social and economic dynamics of hunter-gatherer groups.

The purpose of the article is to deepen the theoretical and methodological foundations of the creation and functioning of family farms in entrepreneurial activity and reveal their socio-economic orientation. Research methods. It is based on the concept of an active policy for the implementation of entrepreneurial potential in the countryside, the components of which are measures for the development of farms and family farms, including through the transformation mechanism of formalizing personal peasant farms into a market economy environment. In the process of research, the following scientific methods were used: dialectical scientific knowledge of processes and phenomena; monographic (analysis of scientific achievements of Ukrainian and foreign scientists, analysis of the stages of business development); graphic (to obtain a synthesized representation of the object of research, identify its components, establish causal relationships); empirical (based on a comprehensive assessment of the current state of the research object); comparative analysis (identified the problems and directions of the formation and development of farming; taking into account the specific conditions of agricultural activity and comparing the processes of farming development at the national level); prognostic (forming the conceptual framework for regulating and improving the entrepreneurship development strategy); abstract-logical (theoretical generalizations and formulation of conclusions). Research results. On the basis of generalization, measures were introduced, in particular, to compensate part of the single social payment (SSP) to family farms, according to the calculations, they can provide in the near future up to 200 thousand such farms (in the total potential of domestic family farming is about a million farms), which is possible both through a change in organizational and the legal form of already existing small farms, and through formalization of personal peasant farms into the market environment, acquiring the official status of physical person entrepreneur - SPE. Analyzing the role of the potential of family farming, it should be noted that its formation affects the development of Ukraine, since agriculture directly or indirectly ensures the achievement of many sustainable development goals provided for by the Sustainable Development Goals of Ukraine for the period up to 2030. The study made it possible to determine the socio-economic orientation and socio-economic efficiency of the development of family farming both for the Ukrainian economy and communities, taking into account the institutional, legal and financial and economic prerequisites for their functioning. Scientific novelty. The methodological representation and identification of the category of family farming have received further development, which is considered here as an organization of agricultural production, forestry, fisheries, livestock, aquaculture, which is managed by the family and can be organized both in the form of an individual and a legal entity. Practical significance. It was revealed that the peculiarity of the functioning of family farms lies in the fact that they simultaneously represent production and consumer unit, and therefore combine two goals - production (maximizing income) and consumer (increasing the well-being of all members of the household). The following models of development of subjects of the rural family economy have been systematized: a model of labor farming; the farm model based on the use of hired labor; family corporation model. It was found that on the basis of the family organization of labor, a small local economy “family farm” is formed, the features of which include: the duality of development goals, that is, the implementation of the entrepreneurial ability of its members to manage the land and maximize income; the reproductive process depends on the existing system of informal institutions; the defining norms of behavior of its members include: loyalty to traditions and cultural heritage, social orientation, innovation, sustainability, trust and predictability of actions of household members; a combination of multi-vector, contradictory processes; a combination of technological, economic and cultural conditions for the functioning of a family farm, which determine the synergistic effect.
