Resultados do PROMAB são divulgados internacionalmente
07/03/2012

O mês de fevereiro de 2012 marca um importante capítulo na história do Programa Cooperativo de Monitoramento em Microbacias (PROMAB), cuja análise dos resultados acumulados do monitoramento hidrológico permitiu a elaboração de um capítulo no livro “River Conservation and Management”, publicado na Inglaterra, a publicação de um trabalho na edição especial sobre “Sustainable Forestry” da revista International Journal of Forestry Research e a apresentação de uma palestra em seminário internacional ocorrido nos Estados Unidos, em Charleston, Carolina do Sul, no período de 22 a 24.

Um resumo do capítulo do livro River Conservation and Management informa que “in spite of their economic importance, forest plantations have attracted widespread criticism from environmentalists, social organizations and academics. These views are based, in part, on popular opinions, beliefs and myths. Despite improving scientific knowledge, the controversy remains; this is because the debate is not simply about calculating the water uptake by eucalyptus or whether streams and soils will dry out – it is far more complicated and involves political, economic, environmental, social and cultural viewpoints. The experimental hydrological studies in Brazil show that, in terms of evapotranspiration and catchment water balance parameters, there is no reason to expect that eucalyptus plantations always represent inherently inappropriate land-use, or that they produce hydrological effects of the same magnitude in all situations”.

River Conservation and Management. Wiley-Blackwell. P. 57-66.

Já o artigo da International Journal of Forestry Research informa em seu abstract que “a case study of a deliberate change in the design of a new Eucalyptus plantation, aimed at alleviating water impacts, was carried out in an experimental catchment located in the center part of the State of São Paulo, Brazil. It involved the identification of saturated areas in the catchment, based essentially on topographic analysis, as a tool to help in zoning of the new forest plantation, with the objective of improving the flow of water to downstream users, as well as to avoid water quality changes. The design involved the allocation of part of the identified saturated areas as water conservation areas, as well as a change in the spacing of the planting. Measurements of tree growth at the age of two years of the new plantation reveal that the forest productivity of the new plantation design, in terms of projected annual wood increment at the end of the rotation, will be similar to the old plantation scheme, despite the loss of planted area. Preliminary results of the continuous monitoring of the catchment water balance appear to indicate that the objective of increasing the catchment water yield may possibly also be achieved.”.
