15. Diagnóstico do uso da água e necessidade de formação de capacidades no meio rural nas regiões administrativas do Brasil / Diagnostic of water use and need for skills training in rural areas of Brazilian administrative regions
The Brazilian territory holds the largest fresh water reserves in the world, around 12% of the total amount available. However, this is not enough to say that there is no water scarcity in this country. Most part of the streams, approximately 80%, are located in the Amazon region, which only 5% of the Brazilian population resides. Therefore, even with high w

17. RECOMPOSIÇÃO VEGETAL UTILIZANDO A REGENERAÇÃO ARTIFICIAL, COM E SEM IRRIGAÇÃO, EM ÁREA CILIAR DO ALTO SERTÃO SERGIPANO. / RECOMPOSITION PLANT USING ARTIFICIAL REGENERATION, WITH AND WITHOUT IRRIGATION IN THE AREA CILIARY HIGH SERTÃO SERGIPE.
Although there are several fragments of vegetation in Semiarid, a lack of techniques for its recovery is observed. Most of the studies about degradation is based on the identification of the locations and degrees of desertification, and recovery practices are few, and when done, they only aim economic aspects, leaving the ecological in second plan. In this c

24. COMPARAÇÃO ENTRE DOIS SISTEMAS HIDRÁULICOS DE MEDIÇÃO DE AGUA DE IRRIGAÇÃO DE ARROZ / COMPARISON BETWEEN TWO HIDRAULICS SYSTEMS OF MEASUREMENT OF RICE IRRIGATION WATER
The irrigated farm crops are the main users of water. With this, in places where there is a water shortage to attend all sorts of use, this kind of activity is characterized like as a potentially conflicting, once that to produce one hectare of rice, are necessary thousands cubic meters of water. To work out this conflict, many actions are been developed, as
