The sustainable management and use of groundwater resources as a source of drinking water supplies, for irrigation, and for other consumptive uses, as well as a supplementary source of surface river flows and of wetlands and wildlife habitats, calls for increasing attention to two major and interdependent sources of concern, namely, depletion and pollution.

Focuses on the existing gap between the traditional design concepts of warabandi - in irrigation water allocation method practiced in Pakistan and Northern India - and its actual practice. Within this focus it also outlines some institutional implications of the present practice of warabandi and identifies further research and policy needs.

Explores the theoretical and actual responses of farmers faced with irrigation supplies that are limited in relation to available land and labor resources, and where the actual schedule and available volume for delivery are uncertain.

Assesses the impact of rehabilitation interventions on irrigation system performance using time series analysis. The study demonstrates that with proper impact specification and model identification, the nature and magnitude of the impacts of different interventions can be separated from the effects of simultaneous changes in dominant exogenous factors.

The System-Wide Initiative on Water Management (SWIM) has defined its central theme and objective as ?enhancing the productivity of water and agriculture in an environment of growing scarcity and competition.? One program area of SWIM, namely SWIM 7, has the aim of improving the utilization of water resources from the catchment perspective. This paper has been prepared as part of the process of planning research that is to be undertaken by SWIM 7.

The main objectives of the workshop were to discuss current insights into the water quality of the Bundala Lagoons, to set priorities for further research, and develop appropriate water management strategies that could improve and sustain the environment of the Bundala Na- tional Park. The workshop brought together a multidisciplinary group of 38 people from 22 governmental and nongovernmental organizations.

Limitations of both the market and the state have caused a growing interest in the potentialities of local-level collective action for development. The burgeoning literature on collective action suffers from two main weaknesses. First, theoretical studies typically fail to describe inter-agent interactions in a satisfactory manner. Second, empirical studies do not provide adequate hard data and quantitative analysis to allow us to advance our knowledge about individual motives for co-operation and conditions conductive to the emergence and evolution of co-operative behaviour.
