ITTO has long encouraged sustainable community forest management as a core part of its work. A good example of its support features in a new video in Portuguese, “Community forest management: a sustainable alternative for the Mau?s State Forest”, produced by ITTO project PD 454/07 Rev.3 (F). The project is helping 19 local communities in the Mau?s State Forest in the Brazilian Amazon to implement good forest management by strengthening community organization, building capacity in the preparation of sound forest management plans, and improving skills in running community forest enterprises.
L'actualité du développement durable avec Médiaterre, le système d'information mondial francophone pour le développement durable concourt à la mise en oeuvre du développement durable dans l'espace francophone par la diffusion et l'échange d'informations, et l'aide à la constitution de réseaux de coopération.
For the CGIAR Research Program on Forests, Trees and Agroforestry (FTA), a research for development (R4D) program, engaging in knowledge sharing fundamentally conditions the program’s effectiveness and impact, both in the policy environment and on the ground. Better sharing leads to better research. That is why FTA, in recent months, has invested heavily in knowledge sharing. For us at FTA, …
A new study has assessed the value of ecosystem-based approaches to mitigating climate changes and conserving biodiversity in Germany. The researchers highlight the trade-offs and synergies between climate adaptation and nature conservation and suggest that effective ecosystem-based climate policy requires improved coordination between different sectors, such as agriculture, forestry and energy.

Accelerated soil loss due to human land use is still one the most critical environmental problems as it can degrade both soils and downstream resources. Major gaps still exist in our knowledge of erosion, particularly in the dry tropics that make up about a fourth of the world's tropical landmass. The Insular Caribbean presents a particular need because erosion here has deleterious effects on soils, nearshore coral reefs, and their associated myriad of ecosystem services. Through plot-scale monitoring of runoff and sediment production over an eleven-month period, this study quantified the impacts of land disturbance on runoff development and sediment production relative to background rates on disturbed surfaces (i.e., roads) in a dry tropical area of Puerto Rico. Results demonstrate that unpaved road surfaces have the potential to generate runoff two to three-and-a-half times more frequently than under natural conditions and that they can produce sediment at rates that are between six to two-hundred times greater than background. These results suggest that land development in small dry-tropical coastal watersheds can potentially induce an increase in the frequency of runoff and sediment delivery into coastal waters even when a relatively small percentage of the land is disturbed. Soil formation simply cannot keep up with accelerated erosion, which implies a net exhaustion of the soil mantle and a decay of the ecological services it provides. Offsetting these soil losses will require implementing proven conservation practices to protect soils and coral reef ecosystems in this and other dry tropical settings.
