ISBN 90 77073 40 X NUGI 835 Foreword The Agrodok series has lacked a booklet describing how water available from rainfall and run-off . from smaller sources than rivers and ground water can be better utilised in agriculture. Antoinette Kome Rob de Neef and Ton van de Ven have filled the gap by writing this Agrodok Water harvesting and soil moisture retention . The contents have also been supplemented by the undersigned. The water harvesting techniques described are particularly useful in arid and semi-arid areas but the techniques described for soil moisture conservation are also of use in sub-humid regions. Theo Meijer Max Donkor and Marc Nederlof have contributed technical advice to this Agrodok. Agromisa is also grateful to Anne Gobin of the Institute for Land and Water Management in Leuven Belgium and to Pierre Chevallier of the Hydrology Department of ORSTOM in Montpellier France for their comments on an earlier version of this Agrodok. Finally without Barbera Oranje this Agrodok would not have been complete for she has drawn and adapted a large number of the illustrations.
