This is one of a series of 10 working papers produced as the first stage of a project to investigate the potential for integration of aquaculture into small-scale, farmer-managed irrigation systems in arid and semi-arid regions of India and Sri Lanka. This part of the project focused on Karnataka State, India, and the papers were produced as a resource for a stakeholder workshop, held in Coimbatore, 19-20 November, 1998.
In this paper, the different types of small-scale farmer-managed irrigation systems of Raichur District, Karnataka State, India, are categorised and their aquaculture potential is assessed. Available water bodies were identified from semi-structured interviews and field visits with the NGO Samuha. Water quality parameters including salinity, phosphate, alkalinity, turbidity, pH, temperature and aluminium were measured. Participatory appraisal was carried out in project villages, and key parameters regarding the use of the water resources and the perceived constraints to aquaculture were identified for subsequent ranking and scoring exercises with farmers.
