 ABSTRACT

The study was undertaken in Kinathukadavu block of Coimbatore district of Tamil Nadu, India. A comparative analysis was made between three irrigation systems namely ground water, both canal and ground water, canal irrigation system and dry land. Sustainable Rural livelihood analyses revealed that both canal and ground water irrigation system was more sustainable than all other irrigation systems and dry land. The optimum planning analyses revealed that groundwater irrigation system satisfied all the three goals of economic, ecological and social goals while all other three systems satisfied economic and ecological goals only. In ground water irrigation system, the economic goal of maximizing profit was satisfied, since optimum plan increased the additional profit by Rs.9980.76 over the existing plan. The optimum plan satisfied two ecological goals namely reduction in usage of phosphorus and potash. The sociological goal of increasing employment for men and women work force were satisfied as the optimum plan increased the men and women labour usage in ground water irrigation system. In both canal and ground water irrigation system, the economic goal of maximizing profit was satisfied, since optimum plan increased the additional profit by Rs.23967 over the existing plan. The optimum plan satisfied two ecological goals namely reduction in usage of nitrogen and phosphorus. In canal irrigation system, the economic goal of maximizing profit was satisfied, since optimum plan increased the additional profit by Rs.17837.67 over the existing plan. The optimum plan satisfied two ecological goals namely reduction in usage of potash and cash expenses on plant protection. In dry land, the economic goal of maximizing profit was satisfied, since optimum plan increased the additional profit by Rs.2673.23 over the existing plan. The optimum plan satisfied two ecological goals namely reduction in usage of phosphorus and potash.

Keywords: Sustainable Rural Livelihood Framework, Optimum farm plan, Goal programming.
