Item Productive Efficiency of Culture-based Fisheries Production in Village Irrigation Systems of Sri Lanka(Reviewing International Encounters 2018,The Research Center for Social Sciences (RCSS), University of Kelaniya, Sri Lanka, 2018) Kularatne, M.G.; Wilson, C.; Robinson, T.; Pascoe, S.Over half of growing global aquaculture production being produced in freshwater ponds and tanks. Asia is the highest global consumer and epicenter of fresh water aquaculture production. Unique Inputs of fresh water fish production in Sri Lanka are multiple use of man-made Common property water bodies fixed in capacity, centralised fish breeding, group labour and collective agreements, natural organic feedings. The development of culture-based fisheries (CBFs) based on stocking fish fingerlings in village irrigation systems (VISs) has grown in popularity over the last three decades. CBF production has been given a high priority in Sri Lanka given fish are a cheap source of animal protein for rural low-income communities. Despite the growing popularity of CBFs associated with VISs, there is little knowledge about factors that influence productivity levels. Therefore, this is the first attempt to investigate on factors influence of technical efficiency of CBF production in Sri Lanka. Primary data from 325 fish farming groups in two districts (Kurunegala and Anuradhapura) are used to estimate a stochastic translog production frontier for CBF production. Analysis of these data indicates that technical efficiency in these irrigation systems is substantially lower than in other aquaculture production systems in a number of other Asian countries, suggesting that production can be increased substantially using existing technology. Removing subsidies, improving consultation with extension officials, and improving water user rights are found to be key means for improving efficiency. In particular, productivity could potentially be improved through the introduction of a transferable community quota system for water rights useItem Technical Efficiency of Small Scale Dairy Farming in Sri Lanka(Research Centre for Social Sciences, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Sheromiha, S.; Kularatne, M.G.The lack of understanding of technical efficiency of small scale dairy farming could have a far-reaching consequence on the productivity and profitability of the farms, and the potentially restricts the need to boost the dairy production. Therefore, this study assesse technical efficiency of smallholder dairy farmers and the factors that cause technical inefficiency. Stochastic frontier production function has estimated from the data collected on the management practices and general information from randomly selected 60 farms in Kosgama Veterinary range in Seethawaka Divisional Secretariat of Colombo District Sri Lanka. The study reveals that mean technical efficiency is 45 with the efficiency range from 40 to 55 indicating that, the dairy farmers were not fully technically efficient. The result also shows that, farmers’ educational level, extension service, years of farmer experience, main source of income, training received, land utilized for fodder and milking frequency have significantly influenced on the technical efficiency. Farmer age, farm size, shad and number of animal are statistically independent variables on technical efficiency. Almost all farmers in Kosgama veterinary range have adopted intensive system with feeding of poor quality grass and concentrates. The average milk production amounted to 60 per cent of the mean daily total of 11.0 litres per cow with average lactating days 250. We conclude that milk production and productivity of small scale farm in Sri Lanka is not significantly effective. It is obvious that if dairy farming is to be a technically efficient sector, there is a need for the small scale farmers to consider dairying as a commercial enterprise and at the same time to link themselves with the large scale dairy farms.
