Reclaiming drainage: toward an integrated approach (English)

This report is the concluding document of the study, Agricultural Drainage: Toward an Interdisciplinary and Integrated Approach, under the Bank-Netherlands Partnership Program-Environment/Water Resources Management Window. The study spanned more than two years of literature reviews, field investigations, and analysis. Work included case studies in six countries representing a cross-section of drainage situations in different climatic zones. The last phase focused on formulating the approach presented in this document. Drainage as a human intervention in the hydrological cycle affects many different functions of natural resources systems and thereby has multiple impacts on society. Global experience provides an overview of some of these effects, positive and negative. The impact of drainage on agricultural production and productivity can be substantial, and drainage investments may have a short payback period. Drainage has a favorable impact on public health and enhances sanitation in rural areas. Improved drainage increases the value of land and buildings and protects roads and other rural infrastructure. On the negative side, drainage has often done much less well in safeguarding vital ecosystems, key environmental processes, and other resources such as fisheries.
