This paper reports on a form of multi-criteria analysis that provides a formal approach for evaluating the suitability of a wetland for specific agricultural uses, and ensures that explicit consideration is given to the possible consequences of such utilization. The method is based on a hybrid of ideas taken from concepts and methodologies related to: environmental flow assessments, land suitability classification and the hazard evaluation procedures used in the design of dams.
This paper focuses on the application of the concept of Integrated Water Resources Management (IWRM) in Tanzania. It asks: how did IWRM affect the rural and fast-growing majority of smallholder farmers' access to water which contributes directly to poverty alleviation and employment creation in a country where poverty and joblessness are high?

In parallel, Integrated Water Resources Management (IWRM) has been promoted in the country and globally as the governance framework that seeks to manage water resources in an efficient, equitable and sustainable manner.
Several traditional methods of maintaining soil fertility in bean-based cropping systems are reviewed as follows: visoso, large- scale chitemene, ngoro or matengo pit (Mbinga District, Tanzania), mambwe land-use system of northern Zambia (fundikila), mounds of the Wafipas (SW Tanzania), tumba land-use system (southern Tanzania), guie (central highlands of Ethiopia), mafuku in Zaire, termite mounds, agroforestry, relay intercropping systems, coffee- banana-bean cropping system of the Wahayas of Bukoba (Tanzania), removal of maize tassels (northern Malawi), and storage of nutrients in weeds (
