| ABSTRACT There is an urgent need for sustainable animal production systems. A system or procedure is sustainable if it is acceptable now and if its expected future effects are acceptable, in particular in relation to resource availability, consequences of functioning, and morality of action. What might make any animal usage system unsustainable? The system might involve depletion of resources such that a resource becomes unavailable or a product of the system might accumulate to a degree that prevents the functioning of the system. However, any effect which the general public find unacceptable makes a system unsustainable. A production system might be unsustainable because of inefficient usage of world food resources; adverse effects on human health; poor... |

| The complexity of the consumers' behavior has taken the food industry to a new level of dynamism. Therefore, understanding the factors that influence this behavior is decisive for the differentiation of products to niche markets and even to adjust the supply according to consumers' expectancy. This article proposes a conceptual model to identify the factors influencing beef consumption in Brazil. The methodological approach was characterized by a systematic review through a synthesis of research related directly to this topic. Therefore, 76 papers published during the 2000-2014 period, including official documents (statistics), full research papers, abstracts, proceedings, and reports, were selected. Four main factors were related to influences in consumer... |

| In the mega-diverse country Peru, a resource intensive development model collides with the interest of conserving biodiversity. Peruvian biodiversity experts have developed different lines of argumentation as to how to integrate conservation into the sustainable development of their country. Applying grounded theory, I define five groups of conservation narratives based on the analysis of 72 qualitative interviews with experts working in areas of biodiversity conservation. I have labeled them: biodiversity protectionists, biodiversity traditionalists, biodiversity localists, biodiversity pragmatists, and biodiversity capitalists. These groups are each discussed in connection with what they have to say about biodiversity in relation to human life,... |

| Like all coastal zones, the cameroonian coast is a complex and diversified environment, controlled by atmospherice, marine and terrestrial phenomena. This diversity is a result of natural changes, human activities, and even the diversity of resources. Coastal zone falls among the most productive ecosystems in the biosphere; they possess specific attributes from which socio-economic development can either benefit, or suffer. Thus their harmfulness is a commensurate with their potentials. In effect, these zones are often subjected to chaotic, and even destructive exploitation wich tends generally to off set the ecological equilibria. |

| Sustainability has become the boiling point of theoretical business discussions. At first it was only a concept everybody was talking about but no one knew how it should be materialized. Now we can understand how and why companies are inclined to follow the principle. This gives the policy makers and other stakeholders the tools to alter market conditions in ways that more and more companies accept the requirements of sustainability. Several levels of sustain-ability have been identified and now the discussion is shifting towards achieving a common ground how to measure sustainability. Since sustainability is such a broad concept and it is very dependant on the factors of the given industry the analyzed company is operating in, two major ways to measure... |

| The social responsibility of businesses has developed into a highly debated issue in recent years. Especially in agribusiness, recent scandals as well as information asymmetries concerning food production have led to high external pressure on firms from the wider public. Being confronted with a variety of stakeholder goals and relationships, it could be particularly advantageous for enterprises in agribusiness to pursue a corporate social responsibility (CSR) strategy. Based on a literature review, we introduce a conceptual framework that provides insights into the determinants of CSR and its effects, in particular, on the legitimacy and reputation, and finally, the performance of enterprises in agribusiness. This contingency-theoretic approach allows a... |

| Results of a research on the macroeconomic dynamics of the Amazon region, in the eighties, that turned unfeasible the traditional agricultural extensive system, which remained so far, and started to demand constant increase in productivity, from the sector, as well as price reduction and better quality of products, without loss of preservation and conservation of the ecosystem. Based on this premise this study was directed to the analysis of the agroforestry production system experiments, carried out by a partnership research with the SHIFT-project, in areas of the Embrapa Amazonia Ocidental (Manaus-AM), with the objective of determining alternatives that could contribute to sustainable development for the Amazon region. The analysis of these systems,... |

| ABSTRACT The aim of this research was to evaluate the agro-economic performance of two table-tomato cultivars (Santa Clara and Siluet), under organic cultivation and in a protected environment. Through the analysis of production costs, economic viability and project risk, it was sought to generate a proposal for agricultural profitability having less socio-environmental impact on family farming. To achieve that, the Operating and Total Production Costs, Net Present Value (NPV) and Internal Rate of Return (IRR) were calculated. A sensitivity analysis and economic risk analysis were then carried out. Both cultivars under consideration presented satisfactory economic indicators for the period being analysed. Judging by the criterion of Net Present Value,... |

| East Africa’s Lake Victoria provides resources and services to millions of people on the lake’s shores and abroad. In particular, the lake’s fisheries are an important source of protein, employment, and international economic connections for the whole region. Nonetheless, stock dynamics are poorly understood and currently unpredictable. Furthermore, fishery dynamics are intricately connected to other supporting services of the lake as well as to lakeshore societies and economies. Much research has been carried out piecemeal on different aspects of Lake Victoria’s system; e.g., societies, biodiversity, fisheries, and eutrophication. However, to disentangle drivers and dynamics of change in this complex system, we need... |

| The purpose of this research was to identify the soil organic matter (SOM) fractions changes in a crop rotation system under no-till system (NTS). This research was carried out from October 2010 to February 2014 in a Rhodic Hapludox. The experiment was set up in completely randomized blocks in a factorial design with eight cover crops and three soil depths (0-5, 5-10 and 10-20 cm) with four repetitions. Cover crops: fall-winter corn, intercropping fall-winter corn with Brachiaria ruziziensis, intercropping fall-winter corn with B. brizantha cv. Marandu, intercropping fall-winter corn with Crotalaria spectabilis, B. ruziziensis, B. brizantha cv. Marandu, Pennisetum glaucum L. and set-aside area. The results of SOM granulometric fractionation showed that... |

| Olive tree (Olea europaea L.) is present in large areas of mainland PortugaL predominantly in less-favored regions. In spite of the fact that irrigated areas are currently increasing, most of the olive orchards are still cultivated under rainfed conditions. The success of olive farming under rainfed conditions is mainly due to the high capacity of olive tree to develop anatomical, physiological and biochemical drought resistance mechanisms. Nevertheless, the productivity is low. We propose cover cropping to control soil erosion, improve soil quality and fertility of rainfed oli\'e orchards. Cover cropping is widespread in fruit farming in temperate climates and in irrigated olive orchards, where water is not a limiting resource. The effects of cover... |
