Utilizou-se a realidade brasileira no que tange o estudo para implantação de PCHs, a legislação nacional e órgãos envolvidos no processo como: Agência Nacional de Energia Elétrica (ANEEL), Agência Nacional de Águas (ANA), Departamento de Água e Energia Elétrica (DAEE) e Companhia Ambiental do Estado de São Paulo (CETESB). O processo de estudo de um potencial hidráulico conta com cinco fases: Estimativa do Potencial Hidrelétrico; Inventário Hidrelétrico; Estudo de Viabilidade; Projeto Básico e Projeto Executivo. Em consonância a este processo é necessário realizar o Estudo de Impacto Ambiental (EIA) e o respectivo Relatório de Impacto Ambiental (Rima). Como ambiente de diálogo entre todos os atores envolvidos, o processo de licenciamento ambiental conta com as audiências públicas, nessas devem ocorrer trocas de informações e conhecimento das demandas dos diversos envolvidos, inclusive da comunidade local, sua efetiva participação é fundamental para a otimização o projeto nos âmbito socioambiental.   Palavras-chaves: PCHs, licenciamento ambiental, comunicação.   THE SHPs STUDY AND IMPLEMENTATION PROCESS AND IMPORTANCE OF ENVIRONMENTAL LICENSING FOR COMMUNICATION BETWEEN ENTREPRENEURS AND LOCAL COMMUNITY   ABSTRACT: The aim of this paper was to present the process of study and implementation of Small Hydroelectric Power Plants (SHPs), local community participation and the importance of their effective participation. The Brazilian reality was used in the study for the implementation of SHPs, as well as, national legislation and public agencies involved in the process, such as: National Electricity Agency (ANEEL), National Water Agency (ANA), Department of Water and Electric Energy (DAEE) and Environmental Company of the State of São Paulo (CETESB). The process of hydraulic potential study has five stages: hydropower potential estimation; hydraulic inventory; viability study; basic project and executive project.  It is also necessary to carry out the Environmental Impact Study (EIA) and Environmental Impact Report (RIMA). According to all the actors involved, the environmental licensing process relies on public hearings, where must occur change of information and knowledge stakeholders demands, including the local community, which effective participation is fundamental for the optimization of the project socio-environmental scope. Keywords: SHPs, environmental licensing, communication.

Abstract The state of São Paulo has a history of habitat loss and fragmentation in endemic areas with projects that threaten its biodiversity. Therefore, this study analyzed how the Environmental Impact Statements (EISs) of mining activities of the state of São Paulo (2005-2016) considered the biodiversity theme in different chapters. To analyze the ten selected EISs, we used the Index of Biodiversity Inclusion (IBI), which reflects the analysis of environmental indicators (from 0 to 1), depending on the commitment presented in each of the indicators. The IBI values ranged from 0.25 to 0.67 with significant variation among EISs. Most of them partially met the criteria, which was a profile similar to other countries, representing information gaps in most of the chapters covering biodiversity. The shortcomings were data limitation, impact analysis, and inadequate mitigation measures, in which the study highlights the need for a better scoping definition previous to Environmental Impact Assessment.

Microelements are an important issue in agriculture, due to their need as micronutrients for plants and also to the possibility of the build-up of toxic levels for plants and animals. Five micronutrients (B, Cu, Fe, Mn, and Zn) are routinely determined in soil analysis for advisory purposes. Other four elements (Cd, Cr, Pb, and Ni) are considered environmentally important heavy metals in farmland soils. Thus high contents of these metals in cropland might go eventually unnoticed. In this paper we present an approach that can be used to monitor the contents of the nine elements in farmland soils using advisory soil testing. A total of 13,416 soil samples from 21 Brazilian states, 58% of them from the state of São Paulo, sent by farmers were analyzed. Boron was determined by hot water extraction and the other metals were determined by DTPA (pH 7.3) extraction. The ranges of content, given in mg dm-3 soil, were the following: B, 0.01-10.6; Cu, 0.1-56.2; Fe, 0.5-476; Mn, 1-325; Zn, 1-453; Cd, 0.00-3.43, Cr, 0.00-42.9; Ni, 0.00-65.1; Pb, 0.00-63.9. The respective average values for São Paulo were: B-0.32; Cu-2.5; Fe-36; Mn-16; Zn-4.8; Cd-0.02; Cr-0.03; Ni-0.18; Pb-0.85. For other states the results are in the same ranges. The higher values are indicative of anthropogenic inputs, either due to excess application of fertilizers or to industrial or mining activities. The conclusion is that massive chemical analysis of farmland soil samples could serve as a database for indicating potential micronutrient deficiency and excesses or heavy metal buil-up in croplands, allowing preventive actions to be taken.
