For co-management of conservation areas to be effective, detailed information on local people's use of natural resources is essential. One method to obtain some of that information, a household record keeping study, is given. It is simple to implement and analyse, and provides useful, quantitative data on resource use and income levels. The method and present data derived from three studies of Melayu and Iban communities in and around the Danau Sentarum Wildlife Reserve in West Kalimantan, Indonesia, are described.

Although irrigation projects often provide water for more than crop irrigation, water allocation and management decisions often do not account for nonirrigation uses of water. Failure to account for the multiple uses of irrigation water may result in inefficient and inequitable water allocation decisions. Decision-makers often lack information on the relative economic contributions of water in irrigation and nonirrigation uses. This report addresses this problem.

Wetlands are habitats with temporary or permanent accumulation of water. The degradation and loss of wetlands is more rapid than that for other ecosystems, and wetland-dependent biodiversity in many parts of the world is in continuing and accelerating decline. They have been confirmed to deliver a wide range of critical and important services vital for human well-being.
