Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops.

O MIMES – Multi-scale Integrated Model of the Earth Sytems Ecological Services é o primeiro modelo global a relacionar a dinâmica entre a tecnologia, produção e bem-estar econômico e os bens e serviços ecossistêmicos do sistema dinâmico da Terra, de forma espacializada. É um “meta-modelo” que representa uma síntese de uma simplificação dos diversos modelos globais dinâmicos existentes nas ciências naturais e sociais em um nível intermediário de complexidade. O objetivo do MIMES é simular o sistema integrado da Terra e avaliar a dinâmica e os valores dos serviços dos ecossistemas.

The economic and land use consequences of US biofuel programs and their contributions to GHG emissions have been the focal point of many debates and research studies in recent years. However, most of these studies focused on the land use emissions due to the first generation of biofuels such as corn ethanol, sugarcane ethanol, and biodiesel (e.g. [1, 2] [3, 4]). A quick literature review indicates that only a few attempts have been made to estimate these emissions for the second generation of biofuels which convert cellulosic materials into liquid fuels. Gurgel et al.

The paper reveals that ever since the 1950s, after the first land reform of distributing landownership (or possession under public ownership) to small farmers, the irrational and polyopolisticland use by able-bodied part-time and absent small farmers earning higher off-farm income butunwilling to lease the under-producing land beyond their family consumption need to full-timefarmers, has been a global obstacle with both public and private land ownership, traditional andmodern agriculture, fragmented small and consolidatorily enlarged land, low and high incomeeconomies, food under-self-suffi

There is a growing recognition that well-defined and enforceable property rights to land are important for a range of economic and social functions. To assess land governance at the country level, the World Bank has elaborated a diagnostic tool based on empirical indicators that aims to identify areas for improvement and that could be used to monitor progress in the land sector.

O objetivo deste trabalho foi estudar a dinâmica de uso e ocupação da terra em Áreas de Preservação Permanente – APPs - na Bacia Hidrográfica dos Rios Mogi Guaçu e Pardo, estado de São Paulo, de modo a subsidiar a formulação de políticas públicas. As APPs foram identificadas e mapeadas usando imagens do Landsat-7. O uso antrópico em áreas de preservação permanente tem sido freqüentemente relatado na literatura, para diferentes regiões do Brasil, com destaque para o uso agrícola. Tal fato também se observa na Bacia Mogi-Pardo, conforme se evidencia neste trabalho.

There is widespread recognition that forestry carbon credits can reduce the net emissions of carbon into the atmosphere. Designing systems to sequester carbon, however, has proven difficult due to a number of efficiency issues, including leakage. Leakage occurs when policy makers develop carbon projects in specific places which protect some parcels of land, but leave other parcels of land unprotected. This analysis uses a newly developed model of global land use change from an established forestry and land use model, described in Sohngen et al.
