Reservoir water reallocation and community welfare.pdf
The introduction of culture-based fisheries (CBF) in small scale irrigation systems is increasing the marginal value of water in rice farming. The amount of water that is used in Sri Lanka for rice farming could be utilised to generate more profitable non-crop economic activities such as CBF. This paper examines whether the re-allocation of water to more efficient, high return uses would increase the total economic welfare of farmer community. Primary data was collected from 460 rice farmers in the Kurunegala District and 334 fish farming groups in two districts (Anuradhapura and Kurunegala) in Sri Lanka. The estimation of the value of water used for rice farming and CBF production is derived from the marginal value product by estimating stochastic translog frontier production functions. We then derive benefit calculations on the basis of the water demand functions for rice and CBF. Reducing the inefficient usage of water in rice farming by 32% increases the volume of water which can be used for CBF production by 53%. This greater efficiency can increase, farmers' total net benefits by 17% per Metres/ha of water used for reservoir-based agriculture. But in order to achieve this benefit, it is critical to ensure the water rights of the multiple users of small scale irrigation systems. This paper recommends introducing a community transferable quota, combined with co-management of water resources, to enhance the welfare of fishing and farming communities which use small scale irrigation systems

Investigation of Socioeconomic Characteristics of Agricultural Communities in Relation to the Development of Culture-Based Fisheries in Non-Perennial Reservoirs of Sri Lanka
Participation of community groups is one of the main requirements for culture-based fisheries (CBF) in
non-perennial reservoirs of Sri Lanka. Homogeneity of the group characteristics facilitates to arrive at
collective decisions. And as such can be considered as positive feature for development of CBF. In this
paper an attention made to identify the most important social and economic characteristics affecting the
group decisions for development and management of CBF in non-perennial reservoirs of Sri Lanka.
Principal component analysis (PCA) revealed that out of 25 measured parameters only 4 namely, the
group size of fishers, participation rate in fisheries activities, caste of community and participation rate for
regular meetings, were important in determining socioeconomic heterogeneity of the sample. Average
income derived from CBF was appreciably high in communities with small group size and high
participatory level in-group activities. Contingent evaluation of willingness to pay also demonstrated that
the involvement of more people with fishing attitude would be preferred for the successful CBF activities.
This analysis indicates that socioeconomic characteristics of rural communities can be meaningfully used
for selecting non-perennial reservoirs suitable for development of CBF in Sri Lanka
