Delta regions are probably the most vulnerable type of coastal environment and their ecosystem services face multiple stresses in the coming decades. These stresses include, amongst others, local drivers due to land subsidence, population growth and urbanisation within the deltas, regional drivers due to changes in catchment management (e.g. upstream land use and dam construction), and global climate change impacts such as sea-level rise.The ecosystem services of river deltas support high population densities, estimated at over 500 million people globally, with particular concentrations in Southern and Eastern Asia and Africa. A large proportion of these people experience extremes of poverty and are severely exposed to vulnerability from environmental and ecological stress and degradation. In areas close to or below the poverty boundary, both subsistence and cash elements of the economy tend to rely disproportionately heavily on ecosystem services which underpin livelihoods.Understanding how to sustainably manage the ecosystem services in delta regions and thus improve health and reduce poverty and vulnerability requires consideration of all these stresses and their complex interaction. This project developed methods to understand and characterise the key drivers of change in ecosystem services that affect the environment and economic status in the world's populous deltas. This was done through analysis of the evolving role of ecosystem services, exploring the implications of changes for the livelihoods of delta residents, and developing management and policy options that will be beneficial now and in the future in the face of the large uncertainties of the next few decades and beyond.The extensive coastal fringe of the Ganges-Brahmaputra-Meghna Delta within Bangladesh were selected as the pilot study area for this work. This is because Bangladesh is almost entirely located on one of the world's largest and most dynamic deltas. It is characterised by densely populated coastal lowlands with significant poverty, supported to a large extent by natural ecosystems such as the Sunderbahns (the largest mangrove forest in the world). It is under severe development pressure due to many growing cities, eg Khulna and the capital, Dhaka. At present the importance of ecosystems services to poverty and livelihoods is poorly understood. This is due to due to the complexity of interactions between physical drivers, environmental pressures and the human responses to stresses and the resultant impacts on ecosystems. Government policy rarely takes up the ecosystems services perspective and as a result an holistic overview of their value is often overlooked. This project aimed to address this gap by providing policy makers with the knowledge and tools to enable them to evaluate the effects of policy decisions on people's livelihoods. The project took a holistic approach to formally evaluating ecosystems services and poverty in the context of changes such as subsidence and sea level rise, land degradation and population pressure in delta regions. This approach was tested and applied in coastal Bangladesh.

Data description (abstract)

This dataset is part of the Ecosystem Services and Poverty Alleviation (ESPA) programme. Ecosystem services provide and underpin wellbeing in all social and ecological settings around the world. A lack of wellbeing can be associated with insufficient ecosystem services, but more often than not a lack of access to them, or their degradation. There is a growing research effort to understand the nature of the processes that link ecosystem services to wellbeing and their temporal and spatial dynamics. We propose four mechanisms by which poverty persists, even in circumstances where ecosystem services are plentiful and sustained over time. These mechanisms are: seasonal dynamics of ecosystem service availability; social relations such as reciprocity, debt and dependence; mobility of both people and resources; and rules of access. This dataset comprises notes and transcripts from qualitative, semi-structured interviews carried out with a range of ecosystem services beneficiaries across Khulna and Barisal Divisions of Bangladesh during the period from October 2012 to May 2013. The objective was to elucidate the relative importance and nature of these mechanisms. Bengali transcripts are also provided where available.
