    Hedged agroforestry (AF) demonstration plots with maize/bean intercrops were studied at Matanya in
    Laikipia district, Kenya, between 1991 and 1995 inclusive, to understand crop yield behaviour due to
    selected soil moisture conservation methods applicable in semi-arid areas. The treatments were:
    Grevillea robusta trees root pruned, compared to unpruned, both in combination with (1) minimum
    tillage and mulching with 3t/ha maize stalks harvested from the plots with additional stalks collected

    The concepts of adaptive management and participatory forest management (PFM) reflect an increasingly holistic relationship between society and its forests. Adaptiveness depends on learning processes. This review considers the ways in which PFM has been assessed in recent literature and focuses on the role of learning, through cross-cutting quantitative analyses, project monitoring and evaluation, and participatory research and experimentation.

    To investigate the degree of forest degradation and the effect of land use change on selected soil quality attributes in loess-derived landforms, samples were taken from different land uses including forest, rangeland, degradated rangeland and farmland in Pasang watershed located in the Galikesh area of Golestan province (37°16'N, 55°30'E). The annual average temperature and mean precipitation of study area were 15°C and 730 mm respectively.

    Los autores se preguntan por el aporte real de los biocombustibles a la solución de los problemas ambientales. Después de analizar las actuales formas de producción en Brasil, sostienen que la expansión de éstos presionará indirectamente hacia la deforestación, contribuyendo así aún más al calentamiento global. Señalan lo falaz del discurso que justifica la expansión de los biocombustibles por su aporte a la generación de empleo.

    Las aves rapaces constituyen un grupo potencialmente sensible a la pérdida y la fragmentación de su ambiente natural debido a sus requerimientos de hábitat extensos y a su baja densidad poblacional. Sin embargo, las rapaces parecen responder de modo diferente a la pérdida del hábitat en ecosistemas templados (donde se observan pocos efectos) y en selvas tropicales y subtropicales (con efectos más marcados). El objetivo de este trabajo es estudiar la respuesta de un grupo de aves rapaces diurnas a la pérdida y la fragmentación de la Selva Paranaense.

    Governments in many countries are decentralising to give more control over decision making and budgets to local administrations. One expectation of this change is that local governments will more effectively and efficiently respond to the poorest citizens in their jurisdictions. Decentralisation is especially significant to forest communities, which have historically benefited little from government services and poverty reduction programmes because of their physical isolation and social marginalisation.
