Abstract
This study employed the Rapid Impact Assessment Matrix (RIAM) to prioritize the water resources management problems in the North Central Nigeria. This was done through the assessment of the status of water resources management in the region, evaluation of existing policy and strategy of water management, identification of the management problems and the prioritization with RIAM. The stakeholders identified water resources management problems, ranked them in other of severity in different categories and also evaluated them using the RIAM techniques in the administered questionnaire. Eleven problems were analyzed based on the physical/chemical, biological/ecological, social/cultural and economic/operational factors using several impact indicators. Scores were assigned, the RIAM models applied and the averages taken to arrive at the final assessment scores. The two major water resources management problems identified are: 1) inadequate funds for further agricultural, hydroelectric, navigation and industrial development; 2) poor data collection and banking. These problems were prioritized by RIAM in order of severity for urgent intervention. The RIAM technique has made a key contribution to the prioritization of water resources management by providing insights into urgent problems according to stakeholders and thus guides the policy maker in appropriate decision making.

The results show that the multi-objective evolutionary algorithms are suitable for application to integrated water resources management and represent a good alternative to the “classical” methods
Summary
Introduction and Literature ReviewNigeria is assumed to be endowed with abundant water that cannot be exhausted; there are increasing indications that contradict this statement. Climate change is making Nigeria increasingly vulnerable to frequent droughts and flash floods with attendant loss of life and property. All these are leading to water crises that need urgent measures to reverse. Nigeria like other sub-Saharan countries loses about 5 percent of its GDP annually as a result of under-development and poor management of water resources. This loss value exceeds the total foreign aid and debt relief inflow into the country [1]
