    As atividades relacionadas à produção agrícola estão entre as que mais têm gerado impactos sobre o meio ambiente. A produção intensiva é grande consumidora de energia, além de fonte de contaminação da água, ar e solo, por meio, especialmente, de resíduos de pesticidas e de fertilizantes. A expansão das fronteiras agrícolas aumenta as taxas de desmatamento, agrava os processos de degradação do solo e põe em risco a biodiversidade.

    A Educação Ambiental surge como política pública no
    Brasil com o estabelecimento da Política Nacional
    de Meio Ambiente – PNMA (Lei nº 6.938, de 1981),
    no contexto da Conferência Intergovernamental de Educação Ambiental de Tbilisi (1977), que destacou o processo educativo como dinâmico, integrativo, permanente e transformador, justamente porque possibilita a aquisição de conhecimentos e habilidades de forma participativa. Desde então, outros marcos legais foram estabelecidos.

    The climate change (CC) caused by increase in atmospheric concentration of CO2 and other Greenhouse Gases (GHGs), can be addressed through adaptation and mitigation strategies. Adaptation consists of strategies which minimize vulnerability to CC. The objective is to increase resilience of the ecosystems and communities through adoption of specific sustainable land management (SLM) techniques that have adaptive benefits. On the other hand, the goal of mitigation strategies is to enhance soil and vegetation (land) sinks for absorbing atmospheric CO2 and to minimize net emissions.

    Timor-Leste, Eastern Asia, Oceania

    The Country Environmental Analysis (CEA) for Timor-Leste identifies environmental priorities through a systematic review of environmental issues in natural resources management and environmental health in the context of the country's economic development and environmental institutions. Lack of data has been the main limitation in presenting a more rigorous analysis. Nevertheless, the report builds on the best available secondary data, presents new data on the country's wealth composition, and derives new results on the costs of water and air pollution.

    In the last 40 years, large areas of the Mau forest, the largest contiguous tropical montane forest in East Africa, have been cleared for agriculture. To date, there are no empirical data on how this land use change affects carbon dioxide (CO2) fluxes from soil respiration and soil methane (CH4) fluxes. This study reports measured annual soil CO2 and CH4 fluxes from the native Mau forest and previously forested lands converted to smallholder grazing land, smallholder and commercial tea plantations and eucalyptus plan- tations.
