16. Dinâmica da produtividade da mão-de-obra na agropecuária de Minas Gerais: um estudo de convergência / Dynamics of labor productivity in agriculture in Minas Gerais: a study of convergence
The agricultural sector in Minas Gerais has experienced a significant increase in labor productivity since the 1960s, due to the use of modern inputs, equipments, and farming techniques driven by the green revolution. Nonetheless, the implementation of the modernization policy which brought about such advances was undertaken in an uneven fashion throughout t

17. Evolution of the human feeding behavior
The main objective of this review is to discuss human feeding behavior based on evolution. With regard to feeding, the human species has undergone various changes during its evolutionary and social history, from the hunting and gathering phase, including the discovery of fire, to modern times, mainly after the implementation of agriculture. These changes exe

18. Enjeux fonciers et gestion des communs dans le Nordeste du Bresil: le cas des vaines patures dans la region de Massaroca- Bahia.
Les vaines patures ou fundo de pasto du Nordeste du Bresil proviennent principalement de terres non appropriees qui ont subsiste entre les latifundia. Dans la region du fleuve Sao Francisco, elles ont fait l'objet d'un programme public de regularisation de titres collectifs de propriete. Cet article situe d'abord cette experience par rapport a l'histoire fon

21. A high-throughput data mining of single nucleotide polymorphisms in Coffea species expresed sequence tags suggests differential homeologous gene expression in the allotetrapoloid Coffea arabica.
Polyploidization constitutes a common mode of evolution in flowering plants. This event provides the raw material for the divergence of function in homeologous genes, leading to phenotypic novelty that can contribute to the success of polyploids in nature or their selection for use in agriculture. Mounting evidence underlined the existence of homeologous exp

23. AGRICULTURE OF PRECISION: MANAGEMENT OF THE FERTILITY WITH APPLICATION OF THE VARIED RATE OF FERTILIZERS AND ITS RELATION WITH CROP YIELDS / AGRICULTURA DE PRECISÃO: MANEJO DA FERTILIDADE COM APLICAÇÃO A TAXA VARIADA DE FERTILIZANTES E SUA RELAÇÃO COM A PRODUTIVIDADE DE CULTURAS
The agriculture of precision has been an important tool for the characterization of the spatial variability of soil attributes and crops. Thus, there is many options to elaborate thematic digital maps that can improve the soil and crop management. In this work, two croplands that has been managed with precision agriculture during several years were selected.

24. A REORGANIZAÇÃO DO ESPAÇO AGRÁRIO DE JÚLIO DE CASTILHOS/RS: UMA NOVA DINÂMICA ATRAVÉS DA LAVOURA EMPRESARIAL DA SOJA / THE AGRARIAN SPACE REORGANIZATION IN JÚLIO DE CASTILHOS/RS: A NEW DYNAMICS THROUGH THE MANAGERIAL SOY FARMING
The insertion of capital makes the territorial units organize and/or reorganize, as it happens in an unequal way in the space according to the demand of the market, considering the local, regional, national and international scales. Consequently, according to the technical degree and the presence of new economical factors, we get the spatial dynamics. At the
