- Abstract:
- Huaynacotas is an isolated village, situated in the Peruvian Andes. The inhabitants depend almost exclusively on agriculture, which strongly depends on irrigation because of the long dry period. By using the lake Huanzo for storing water during the rainy season and conveying this water to the fields of Huaynacotas, the actual water supply shall be increased in the near future. It is the objective of this study to find a sustainable way to distribute this increased supply: Therefore firstly the actual irrigation practice was analyzed and its main characteristics, were identified. This was done in a participatory way in order to obtain the farmer¿s view of the applied irrigation practice: Water is provided to the fields of Huaynacotas by two main irrigation schemes, managed and maintained by the users themselves. The distribution is done ¿canto a canto¿ (neighboring fields are provided in a fixed sequence) from the tail to the top of the schemes. Thanks to the high transparence of this distribution easy control is possible. Neither stealing of water nor giving preferential treatment to certain persons occurs. The irrigation infrastructure is maintained in form of communal work days which are efficiently organized and controlled by an irrigators commission (Comisión de Regantes). By realizing the project Huanzococha ¿ the storage of water in the mountain lake Huanzo and its conveyance to the cultivated grounds of Huaynacotas ¿ the irrigation interval could be reduced and actually abandoned area could be taken under command again. Combinations of these two possibilities were combined concerning their sustainability considering the aspects productivity, security, protection, economic viability, social acceptance and institutional viability. Maintaining the actual irrigation practise and recuperating aproximately 30 hectares of actually abandoned area in relatively good estate, turned out to be the most recommendable alternative.
