2. RAINFALL ZONING FOR COCOA GROWING IN BAHIA STATE (BRAZIL) USING FUZZY LOGIC
ABSTRACT Cacao is a species of great economic and social importance. Expanding the area grown with this crop has been limited by its climatic requirements. Agroclimatic zoning for agricultural sector and creation of land suitability maps by fuzzy logic contribute to such production expansion. In this sense, this study aimed to develop rainfall zoning for cac

6. Diagnosis of the Accelerated Soil Erosion in São Paulo State (Brazil) by the Soil Lifetime Index Methodology
ABSTRACT: The soil is a key component of the Earth System, and is currently under high pressure, due to the increasing global demands for food, energy and fiber. Moreover, the management of agricultural systems is often inadequate and ignores the agricultural suitability of lands, and particularly the vulnerability of soils. This paper demonstrates the appli

12. Seleção de áreas aptas a disposição de lodo de estações de tratamento de esgoto com fins agrícolas / Selection of areas suitable for the disposal of sludge stations sewage treatment for agriculture
Overcrowding in urban centers has spawned many impacts on the environment, highlighting the waste generated by their activities. To properly allocate these wastes, technologies are developed such as those involved in sewage treatment. However, this form of treatment also generates waste, which must be treated and disposed of properly. The sludge is a byprodu
