HR Wallingford, in conjunction with the International Commission on Irrigation and Drainage (ICID) and the United Nations Food and Agriculture Organisation (FAO), have been involved over the last few years in preparing an environmental checklist and a guide to environmental impact assessment (EIA) for use specifically in irrigation and drainage (l&D) work. The purpose of both these documents is to enable in-country professionals, with an l&D background, to systematically take environmental issues into account. The checklist is a tool to guide data collection and assist in scoping environmental studies, a process which is further elaborated in the guide. They both make it much easier for planners and managers to take environmental issues into account in an integrated manner when actions are first proposed. This paper sets out the procedures described in the existing documents and makes suggestions for how to use and adapt them to suit the Aral Sea Basin.This paper proposes that a systematic format for assessing the environmental effects of actions at all levels would firstly minimise negative effects and maximise positive ones and, secondly, provide a means of collating information on environmental impacts and thereby improve environmental management. A nesting arrangement of procedures would have to be adopted to suit the scale of activity being undertaken. For, example, local drainage developments would require less data collection and fewer analyses than a regional irrigation management plan. The strength of the proposed approach is that standard forms and procedures could be usefully used by professionals who are not necessarily environmental experts. Very large projects funded by international aid would almost certainly require fullscale EIA’s as a condition of the loan. The guide to EIA in I&D, as developed, would be of value in these cases.It has been stated repeatedly that the Aral sea crisis cannot be managed without extensive training and with most work being carried out by existing personnel. The Checklist, published in 1993, has proved of great value as a teaching tool as well as useful in the field. Training in its use is also a learning experience in understanding environmental issues. The development of documents for use in the Aral Sea basin, that are straightforward to use and written in a familiar language, would help to disseminate knowledge, contribute to the proposed monitoring programme and make use of available data at all levels. This would help local decisions to be environmentally sustainable locally and environmentally considerate for other users of the basin.
