“…The dominant natural vegetation in São Paulo is the Atlantic Forest, which is both a high-priority area for biodiversity conservation (Joly et al 1999, Myers et al 2000 and the most urbanized and densely populated area of Brazil (Hogan 2001 ). In eastern São Paulo, along the Serra do Mar mountain chain, lie the most signifi cant remnants of the Atlantic Forest, which form a mosaic of legally protected areas (Ribeiro et al 2009 ).…”

Forest systems play a crucial role in biogeochemical cycling and provide a variety of ecosystem services at multiple scales. Considerable progress has been made in understanding the dynamics of tropical and temperate deforestation and land-use and cover change. However, less attention has been dedicated to understanding the social and biophysical conditions under which reforestation occurs. Recent research documents the experiences of many countries that have undergone transitions from a period of high deforestation to a period of declining deforestation or even net reforestation. However, these transitions take place across a range of temporal and spatial scales. Here, we review global forest-cover trends and social processes affecting forest cover and then focus on a comparison of reforestation in Chapter 4

“…Como salienta Tanaka e Nishii (1997), a variável população incorpora implicitamente outras variáveis, tornando-as desnecessárias, além disso, ela é de fácil mensuração, o que facilita os trabalhos de natureza empírica. No entanto, considerar a população como única variável explicativa do desmatamento não capta as verdadeiras razões para o desmatamento, a exemplo das ações econômicas(HOGAN, 2001).…”

The unequal deforestation in the Amazonian Region: its evolution, causes and consequences on the welfare The thesis analysis Amazonian Region's deforestation, highlighting its unequal evolution among the Amazonian states and points out its causes as well as evaluates the impacts on welfare if the deforestation is reduced. The thesis is organized in three articles following the nonconversional form allowed by "Luiz de Queiroz" College of Agriculture. The first article, Amazonian region's Ocupation Process and its deforestation-basing on the literature review and on published dataset and following the time chronology of the events since the Portuguese colonization-analyzes the stages of Amazonian region development and its consequent deforestation, highlighting the policies addressing to foster the Amazon's development and the current stage of economic activities. The population growth and the economic activities, pointed out as the main causes of the Amazonian deforestation and stimulated by economic policies, have been unequally developed inside the Amazonian region, generating the unequal deforestation process among the Amazonian states and inside each state. The second article, Recent Determinants of Legal Amazonian Region's Deforestation, evaluates, by using econometric procedures, the causes of deforestation normally emphasized by the literature and considering the time period from 2000 to 2004. The analysis is conducted for the entire Amazonian region and for each of its nine states and using municipal dataset. All explanatory variables except roundwood extraction and expenses in agriculture showed statistically significant to explain deforestation in the entire Amazonian Region. However, the same does not take place for each Amazonian state, what explains the unequal deforestation among them. By the end, the paper suggests some policies to restrain deforestation. The third article, The Analysis of Relationship Between Deforestation and Population Welfare in the Legal Amazonian Region, examines the empirical relationship between Amazonian rainforest deforestation and local population welfare, measuring the impact on welfare if the deforestation area is reduced. A Municipal Human Development Index-IDH-M was used to measure welfare. Using 1995 Agriculture Census dataset, a Cobb-Douglas production function was estimated considering three production inputs: capital, land and labor. Applying a nonlinear programming method on the results came from the production function, the impacts of land constraints on agriculture and agribusiness incomes could be calculated, generating a new value of income for each Amazonian state. Combining the new values of income with education and life indexes, a new IDM-H was estimated for some Amazonian states. The results point out IDM-H has small reductions, despite of significant reductions on some states' income, if some restrains were established on arable land use.
