Over the past century, mires and peatlands have faced a wide range of degradation by artificial drainage, making them one of the most threatened ecosystems in Europe. However, restoration of drained peatlands has gained much importance over the last three decades, mostly due to the multiple ecosystem services they provide such as carbon storage, ha...

Final version: https://authors.elsevier.com/a/1bxBy5rRUJuKiU ______________________ Alkaline fens are ecosystems with extraordinarily high biodiversity. However, they belong to the most threatened ecosystems in Europe due to drainage, land use intensification and cessation of traditional management. In such systems, evapotranspiration (ET) is an i...

(download final version at https://authors.elsevier.com/a/1bjcsB8ccoKaV) Precipitation is a key factor affecting shallow water table fluctuations. Although the literature on shallow aquifers is vast, groundwater response to precipitation in peatlands has received little attention so far. Characterizing groundwater response to precipitation events...

Fens belong to the most threatened ecosystems in Europe. Maintaining a high water table through rewetting is an effective measure to rehabilitate many of their ecosystem functions. However, the impact of meteorological conditions such as vapor pressure deficit (VPD) and precipitation on water tables is still unclear for rewetted fens. Here, we compa...

The Ganges-Brahmaputra (GB) delta is one of the most disaster-prone areas in the world due to a combination of high population density and exposure to tropical cyclones, floods, salinity intrusion and other hazards. Due to the complexity of natural deltaic processes and human influence on these processes, structural solutions like embankments are i...

Although roads are important cultural objects in our society, they can have negative impacts on the environment. Bat populations are affected by roads in several ways, including habitat loss, death due to collision with vehicles, and reduced habitat connectivity. In recent years, different mitigation practices have been introduced to help animals s...

Over the last century, peatlands have undergone severe degradation. Nevertheless, the restoration of drained peatlands has gained much importance over the last decades. Hydrological processes are closely linked to soil properties and as such investigations of both water dynamics and soil properties are vital. The specific objectives are to evaluate...

Many delta countries acknowledged threats from increased salinity such as Vietnam, Bangladesh, Ghana, and the Netherlands. Salinization in Bengal delta usually been framed as secondary impact of climate change and sea level rise considered being one of the major drivers of salinization process. However, many local (shrimp cultivation) and regional...

While the benefits humans gain from ecosystem functions and processes are critical in natural resource-dependent societies with persistent poverty, ecosystem services as a pathway out of poverty remain an elusive goal, contingent on the ecosystem and mediated by social processes. Here, we investigate three emerging dimensions of the ecosystem servi...

Of all terrestrial ecosystems, peatlands store carbon most effectively in long-term scales of millennia. However, many peatlands have been drained for peat extraction or agricultural use. This converts peatlands from sinks to sources of carbon, causing approx. 5% of the anthropogenic Soil Syst. 2020, 4, 14 2 of 27 greenhouse effect and additional n...

Climate change affects almost all aspects of human life, including health. This is particularly true in densely populated and low lying deltas such as Bangladesh. However, the climate‐health nexus is a relatively poorly explored domain of research, which is a cause for concern given the country's intrinsic vulnerability to climatic impacts. The imp...

Social survey and geographical data, stratified by social-ecological systems, are used to analyse multiple measures of poverty, in-depth information on rural livelihoods and coping strategies for populations in the delta region. The resultant dataset provides extensive information on the ways in which households use ecosystem services to generate w...

Demographic trends and projections have important implications for the use of ecosystem services and sustainability in the delta. The study area accounts for ten per cent of the national population and recently appears to have low rates of population growth. Analysis of components of population change (fertility, mortality and migration) indicates...

Health, livelihoods and well-being are interdependent, and recognising the link with ecosystem services is essential. Food shortages, limited sources for drinking water affected by salinity levels, reduction in the protective systems of the delta and change in the frequency or intensity of extreme events can all have impacts on the health and well-...

Salinity in drinking water in coastal Bangladesh linked to high blood pressure

In this chapter we will mainly focus on biodiversity challenges in relation to human health. We will do this from a science-society interface perspective. What are the important challenges regarding this topic when aiming for policy and society practice relevant reseaerch and action? First, we will briefly introduce the main biodiversity-human heal...

Although Bangladesh has steadily made progress towards alleviating food insecurity, around one fourth of the population had to worry about food in 2014. With a projected increase in the frequency of severe weather events, climate change along with population growth, degradation of soil fertility, and decreasing arable land threaten future agricultu...

In a time of climatic and environmental change, perception studies are important for countries with limited funding for environmental research. Coastal populations of Bangladesh, as with many other countries, are living with and experiencing changing environmental quality on a daily basis. Therefore it may be possible to capture, through their lens...

Our understanding of how climate change is affecting marine ecosystems, particularly for the South Asia region, is lagging.

Populations in resource dependent economies gain well-being from the natural environment, in highly spatially and temporally variable patterns. To collect information on this, we designed and implemented a1586-household quantitative survey in the southwest coastal zone of Bangladesh. Data were collected on material, subjective and health dimensions...

Abstract Fens are mire (peatland) ecosystems often rich in plant diversity and are recognized as one of the most threatened ecosystems in Europe. In such ecosystems evapotranspiration is an important hydrological process as it may sometimes be the principal way through which water is lost. Therefore this study aims at determining evapotranspiratio...

As a creeping process, salinisation represents a significant long-term environmental risk in coastal and deltaic environments. Excess soil salinity may exacerbate existing risks of food insecurity in densely populated tropical deltas, which is likely to have a negative effect on human and ecological sustainability of these regions and beyond. This...

This paper provides an overview of population dynamics and scenarios of population change in the environmentally vulnerable coastal Ganges Brahmaputra Delta region. The main data sources used for the study include the most recent and historical census data, data from the Sample Vital Registration System (SVRS) and Demographic and Health Surveys (DH...

The key function of the scenario development process in the ESPA Deltas project is to link the concerns and priorities of relevant stakeholders with the integrated models. Once the biophysical models have been integrated, these will be combined with the poverty / health outputs of the project. In order to fully facilitate the connection between sta...

This chapter explores the internal migration patterns occurring in certain erosion prone areas of Bangladesh. It focuses on the chars of the districts of Kurigram and Gaibandha, where an empirical research study was conducted involving around 350 participants. The chars are temporary islands that are naturally formed through erosion and accretion i...

Bangladesh has been identified as one of the most vulnerable country to the impact of climate change and sea level rise. However, unlike the physical dimensions of climatic impacts, there exists a significant knowledge gap in understanding the association between climate change and health especially when the context is related to a developing count...

This study looks into the different socio-economic and demographic determinants of household food security by analyzing the possible associations that food security has with factors such as flood protection, microcredit access, amount of agricultural land owned, main source of household income, household size as well as income diversity. Using data...
