    In view of the continuing increase in cost and scarcity of mineral fertilizers resulting from the use of high-cost fossil energy, there is renewed interest in organic recycling and biological nitrogen-fixation to improve soil fertility and productivity. The workshop in Alexandria recommended the further promotion of research, development, application and dissemination of information available on various aspects of biological nitrogen-fixation, including symbiotic systems of rhizobia/legume and Azolla/blue-green algae, and free-living nitrogen-fixing bacteria and blue-green algae.

    There is a urgent need for a better understanding of the risks of soil degradation and their geographical distribution as well as a better knowledge of where degradation occurs at present. it would be desirable to combine soil conservation activities with other elements for increasing crop production.Erosion, salinity and alkalinity and the loss of soil fertility seriously reduce the natural potential of soils to produce food fibres. During the meeting, many criteria to assess the various types of soil degradation were outlined by the experts.

    Land Tenure Working Paper 1. This document analyzes the implications for land tenure and land policy of biofuels. It examines the current and likely future impacts of the increasing spread of biofuels on access to land in producer countries, particularly for poorer rural people. It aims to pave the way for future empirical research on the links between the spread of biofuels and access to land, through developing a conceptual framework for such research and through taking stock of data available in the literature.

    The Action Against Desertification (AAD) project supports eight ACP countries, Burkina Faso, Ethiopia, Gambia, Niger, Nigeria, Senegal, Fiji and Haiti in the sustainable management and restoration of degraded land. Baseline assessments have been carried out in each of these countries to establish a reference against which to monitor changes and project impacts, as well as to better target project activities and inform other stakeholders and restoration initiatives in these countries.

    The Re-Greening of the West African Sahel has attracted great interdisciplinary interest since it was originally detected in the mid-2000s. Studies have investigated vegetation patterns at regional scales using a time series of coarse resolution remote sensing analyses. Fewer have attempted to explain the processes behind these patterns at local scales. This research investigates bottom-up processes driving Sahelian greening in the northern Central Plateau of Burkina Faso—a region recognized as a greening hot spot.
