The Daudkandi model of community floodplain aquaculture in Bangladesh: a case for Ostrom’s design principles

Floodplain water-bodies are one of the major common-pool resources (CPRs) of Bangladesh and constitute more than fifty percent of inland open water bodies. Throughout the British colonial period, Pakistani rule and the first one and half decades of independent Bangladesh, a majority of inland water-bodies remained under direct government management, though the floodplains, by getting heavily inundated during the monsoon, turn into an open access resource. In the mid-1980s, co-management was introduced on a small scale with the help of NGOs as providers of management styles and credit to communities of fishers or villagers. NGOs also got involved in floodplain water-bodies and came up with different models of user-managed fishery bodies. This paper examines a specific management system of community-governed floodplain aquaculture (FPA) known as the Daudkandi model, developed by a local NGO in the Daudkandi sub-district of the Comilla district. Applying the design principles developed by Ostrom (1990) characterizing long surviving successful user-managed commonpool resource institutions, this paper explores the rules devised by partners in the management of a FPA under the Daudkandi model. Though the FPA management model is relatively new (i.e. it has been adopted in 1996) it has been found to follow the design principles in devising its management rules. However, because of its unique features in terms of seasonality, the NGO-community partnership, the exclusion of past users, and numerous replications, the future of the model as a CPR governance system holds many challenges and deserves a continuous research focus. c 2016, Igitur, Utrecht Publishing and Archiving Services.

Measuring the efficiency of collective floodplain aquaculture of Bangladesh using Data Envelopment Analysis

This study measures efficiency of collective floodplain aquaculture enterprises (FPAs) practiced in floodplains composed of private lands in Bangladesh using data envelopment analysis (DEA). We concentrate on a management system that was initially developed by landowners in the Daudkandi sub-district in 1984. With gradual spread of this management system two important internal variations have emerged in terms of (1) organizational composition that resulted from the investment-based participation of an NGO, and (2) mode of managing aquaculture operation that resulted from leasing out the aquaculture operation instead managing it by themselves in some FPAs. Taking consideration of these two variations, and using four inputs and one output, we measure the technical, scale, mix and overall efficiency of 15 FPAs selected from five districts. While 11 FPAs are technically efficient, only six are overall efficient. On average, NGO-collaborated FPAs (NFPAs) are more efficient (78.27%) than landowners-managed independent FPAs (IFPAs) (75.96%). However, IFPAs are only found in the Daudkandi region, where there are more efficient IFPAs than NFPAs. On the other hand, while lease-based operations show better average efficiency (79.56%), self-managed operations have more efficient units. We also find that the intensive use of inputs in most older FPAs does not make them more efficient, despite their higher fish yield, than relatively newer FPAs. Given the poverty, food security and nutrition linkage of floodplain aquaculture and continuous attempts to increase fish yield, the FPAs along with development partners and government agencies, should take account of efficiency-related aspects in policies and practice
