A. ESPA Delta Project
Assessing Health, Livelihoods, Ecosystem Services And Poverty Alleviation In Populous Deltas

Project Aims

This project aims to provide policy makers with the knowledge and tools to enable them to evaluate the effects of policy decisions on people's livelihoods. This is being done by a multidisciplinary and multi-national team of policy analysts, social and natural scientists and engineers. Collectively they are using a participatory approach to create a holistic approach to formally evaluating ecosystem services and poverty in the context of the wide range of changes that are occurring. These changes include subsidence and sea level rise, land degradation and population pressure in delta regions. The approach is being developed, tested and applied in coastal Bangladesh, but is expected to ultimately be applicable in other deltas.

The Ecosystem Services (ES) of river deltas often support high population densities, estimated at over 500 million people globally, with particular concentrations in South, South-East and East Asia and Africa. Further, a large proportion of delta populations experience extremes of poverty and are highly vulnerable to the environmental and ecological stress and degradation that is occurring.

Rural livelihoods are inextricably linked with the natural ecosystems and low income farmers are highly vulnerable to changes in ecosystem services. Their health, wellbeing and financial security are under threat from many directions such as unreliable supplies of clean water, increasing salinisation of soils and arsenic-contaminated groundwater, while in the longer term they are threatened by subsidence and sea-level rise. This study will contribute to the understanding of this present vulnerability and help the people who live there to make more informed choices about how best to reduce this vulnerability. In particular, the project is working with national stakeholders.

B. DECCMA Project (DEltas, Vulnerability and Climate Change: Migration and Adaptation)

Large tracts of land at low lying elevation make deltas vulnerable to sea-level rise and other climate changes impacts. Deltas have some of the highest population densities in the world; in total with 500 million, often poor, residents. The adaptive strategies available to deltas residents (e.g. disaster risk reduction, land use management or polders) may not be adequate to cope with pervasive, systematic, or surprise changes associated with climate change. Hence large movements of deltaic people are often projected under climate change. DECCMA is an approximately 5 year long programme of applied research on the adaptation options, limits and potential in deltaic environments to current weather variability and extremes, as well as climate change.

Aim of the project are:

a.   to assess migration as an adaptation in deltaic environments under a changing climate;

b.   to deliver policy support on sustainable gender-sensitive adaptation in deltaic areas.


Better understand in deltas:

a.   migration processes, including the role of climate change

b.   adaptation approaches, including the possible role of migration.

This will take a participatory and adaptive pathway approach that addresses gender dimensions?

The objective of DECCMA are :

a.   to understand the governance mechanisms that promote or hinder migration of men and women in deltas;

b.   to identify climate change impact hotspots in deltas where vulnerability will grow and adaptation will be needed;

c.   to understand the conditions that promote migration and its outcomes, as well as gender-specific adaptation options for trapped populations, via surveys;

d.   to understand how climate-change-driven global and national macro-economic   processes impact on migration of men and women in deltas;

e.   to produce an integrated systems-based bio-physical and socio-economic model to investigate potential future migration under climate change;

f.    to conceptualize and evaluate migration within a wide suite of potential adaptation options at both the household and delta level;

g.   to identify feasible and desirable adaptation options and support implementation of stakeholder-led gender-sensitive adaptation policy choices.


The analysis will guide sustainable and equitable development of deltas and will:

a.   identify gender-differentiated stakeholder-relevant scenarios of local/regional/delta  level vulnerability to climate change;

b.   identify options for effective climate adaptation by the poorest groups in deltas; and

c.   lead to the development of gender-sensitive adaptation funding proposals in the four  deltas
