  Citation × Citation Citation Abstract Copy Title: Determinants of Land Leasing Decisions for Shrimp Farming: A Case Study of Smallholders' Shrimp Farming In India Author: Bhattacharya, Poulomi Using primary data collected from 208 shrimp farming households and 69 households leasing-out land for shrimp farming, this paper explores the demographic and economic factors influencing the land leasing decisions for traditional and scientific shrimp farming in West Bengal, India, applying Tobit Model. The results indicate that size of households‟ land holding is positively related with the extent of land leased-in for traditional shrimp farming whereas for scientific shrimp farming the association was found to be negative. This signifies that land leasing market does not facilitate the households having lesser landholding to lease-in land for shrimp culture in the case of traditional shrimp farming whereas in the case of scientific shrimp farming it does facilitate such households. In the case of traditional shrimp farming households‟ association with other fisheries related activities was also found to have positive influence on their leasing-in decisions . On the supply side, variables like number of adult male members, households‟ association with fisheries related activities and non-farm assets were found to have positive, negative and positive association respectively with the extent of land leased-out for traditional shrimp farming. The analysis also exhibits that the age of the household head has negative relationship with the extent of land leased-out by them both in the case of traditional and scientific shrimp farming. This signifies that existing institutional arrangements in shrimp farming of West Bengal are not considerably successful to motivate young rural people to undertake shrimp farming on their own instead of leasing-out land for shrimp culture and aquaculture policies should address this aspect.

  Citation × Citation Citation Abstract Copy Title: Farm-Level Efficiency and Resource-Productivity: Application of Stochastic Frontier Analysis to Aquaculture Farms in the South-West Nigeria Author: Ogundari, Kolawole This paper comparatively examined resource-use and technical (TE) efficiencies of aquaculture farms in the Southwest Nigeria. A total of 160 farms were randomly selected from four states across the region. Econometric applications of the stochastic frontier models provide measure of the farm’s technical efficiency. The results of regressions specified for the farms in each states, show that, elasticites for inputs, such as: size of the pond, feeds, labour, numbers of fingerling stocked, and costs of materials were positive and significant. This suggests that, the production functions monotonically increased with input from the study. The returns to scale estimates show that, an average farm in the states like, Ogun and Ondo exhibit increasing returns to scale, while similar numbers of farms in Osun and Ekiti states exhibit decreasing returns to scale. The results of marginal value product (MVP) show that, none of the farms across the states optimally used their variable inputs (MVPx =MFCx). Most farms were found to have underused (MVPx >MFCx) feeds and numbers of fingerlings stocked, as against overused (MVPx <MFCx) of labour across the states. The estimated TE shows that, about 11%, 18%, 22% and 44% of outputs of the farms in Ogun, Ondo, Ekiti and Osun states are forgone due to inefficiency respectively. The implications of these findings, therefore, suggest that improvement in the technical efficiency of the farms, as well as, optimal input utilization, will contribute significantly to aquaculture expansion program in the county.
