The coastal region of Bangladesh is prone to natural disasters and these events are expected to worsen as a result of climate change. Combined with anthropogenic factors, these events challenge livelihood opportunities, especially crop production. Waterlogging, tidal activity and the lack of proper drainage facilities are major constraints to agricultural production in these areas.
The CGIAR Research Program on Water, Land and Ecosystems (WLE) tested, at pilot scale, the combination of innovative agricultural technologies with improved water management to overcome these challenges.
This report assesses this intervention by observing the effects, measuring the short-term impacts and understanding the perceptions. The results highlight the need to integrate the interventions into the local context, and acknowledge that institutions and markets need to mature to harness the benefits from innovations. It also underlines the potential of multi-scale interventions combining plot-level and farmer-led innovations, community management and rehabilitation of large schemes.

To deal with large uncertainties about future climate and socio-economic developments, planners in deltas are adopting an integrative and adaptive planning approach referred to as Adaptive Delta Management (ADM). Bangladesh has used the ADM approach for the development of its adaptive plan; Bangladesh Delta Plan 2100 (BDP 2100). The success of policy strategies in an adaptive delta plan critically depends on a specific adaptation of livelihoods of local communities (Community Livelihood Adaptation; CLA), especially in an agriculture-oriented society like Bangladesh. For example, while triple rice cropping might be evaluated as a robust strategy in all futures considered, its success eventually depends on whether farmers’ will actually make that choice, which is deeply uncertain. In this paper, we use literature review, insights from interviews and field observations to examine how the uncertainty in CLA impacts (adaptive) delta management. We study two historical cases of livelihood adaptation of farmer communities confronted with salinization and waterlogging in the polders of southwest Bangladesh since the 1960s. We conclude that historically the uncertainty about CLA in polders has been ignored in the development of policy plans, leading to the failure of anticipated policy outcomes. We recommend planners in Bangladesh and other deltas worldwide to take account of CLA as uncertainty when developing long-term adaptive plans.

Polders in the floodplains of the Ganges-Brahmaputra delta in Bangladesh play a critical role in supporting intensive agricultural production and the livelihoods of around eight million people. Polderization is promoted to reduce environmental vulnerabilities against flood inundation, coastal erosion, and salinity intrusion. These land areas are low-lying islands consisting mainly of alluvial sediment deposits, and almost half (~1.2 million ha) of the coastal zone in the region is polderized. Agriculture is the primary reason for the polderization of the region, where paddy rice is the major irrigated crop. Around 139 polders in Bangladesh spread across the Gangetic-Brahmaputra delta region, and they altered the delicate balance between human activity and the floodplains' natural hydrological process, resulting in numerous evolving problems. These include the geomorphological evolution of the river channels and flood plains, water logging and drainage congestion within the polder system, sea-level rise, tidal surges, and salinity intrusion. Coastal and inland salinity is a significant problem in these polders, often influencing crop yields and further agricultural productivity and freshwater availability. We explicitly look at two polders to evaluate the distinct socio-hydrological characteristics of these systems. We used several secondary data sources and literature (grey and scientific) to evaluate the hydrological characteristics, groundwater heterogeneity and social dynamics to understand and evaluate the underlying mechanisms and intrinsic links between systems that influence water balance, saline water intrusion, and crop production. The initial results highlight the complex dynamics of the polder system, often influenced by water availability, irrigated water use, seasonality, and, above all, stakeholders' perceptions. Overall, this work provides an improved understanding of the biophysical dynamics and social linkages and sets the basis for implementing a larger detailed socio-hydrological framework.
