This document represents the final report of R7868, 'Maximisation of joint benefits from multiple resource use in Bangladeshi floodplains'. The report describes project activities and outputs, including the investigation of a number of management strategies with wide applicability across Bangladeshi floodplains, and the development of a set of recommendations.
The project undertook desk-based simulation modelling of a set of management strategies that have wide relevance across the floodplains of Bangladesh. The modelling exercises brought together previously generated data, parameters and knowledge from the agriculture and fisheries sectors within an integrated framework. This was complemented with secondary socio-economic information to provide fresh insights into how these strategies may be positioned in order to optimise their role in improving floodplain livelihoods. A suite of modelling approaches were utilised or developed for this purpose: (i) A dynamic pool fisheries model with a hydrological component, (ii) GIS modelling connecting plot level cropping with socio-economic information, and (iii) A mathematical programming model optimising the productive use of land with joint consideration of the two sectors given a set of hydrological, biophysical and economic constraints. These were used to investigate the following strategies: (i) fisheries closed seasons (ii) fisheries closed areas, (iii) Limiting water abstraction for winter rice irrigation, (iv) higher dry season water retention, (v) managing early flood risk by non-structural means and (vi) early flood season sluice gate management.
