Notas del editor
- After water demand for different sectors
- Our recommendation then is that agriculture be included in any mitigation funding modalities, with funds available for development and implementation of low-cost monitoring systems and that allow innovative payment mechanisms to address the characteristics of agriculture, especially in developing countries, where small producer predominate and legal institutions are not always fully effective. The principle of common by differentiated responsibilities implies that any funding should support mitigation of agricultural emissions by the poorest but as countries progress and their incomes rise, the burden of mitigation should be adjusted too. 5) Linking communities to global markets - Establish regional centers for carbon trading, specialized business services and local intermediaries. Simplify standards for small-scale projects. Deal with permanence issue in carbon sequestration.
