Anthropogenic heavy metal pollution in surface waters – Field trip to Tamil Nadu, South India

Tank Chidambaram (Groß).pngDr. Linda Taft (Department of Geographie, University of Bonn) and her colleague PD Dr. Sven Sindern (Institute of Mineralogy and Economic, RWTH Aachen) travelled to the Indian state of Tamil Nadu from Feb 21 to Mar 06, 2020, to conduct fieldwork for their current DFG-Project. The project „Shells of aquatic freshwater gastropods as archives for heavy metal contamination history of a river-coast transition zone“ is a proof-of-concept study in order to assess the suitability of the shells of aquatic gastropods (snails) as environmental pollution archives. Dr. Taft and PD Dr. Sindern sampled gastropod shells from different water bodies such as urban water tanks and brackish to freshwater river zones, where anthropogenic heavy metal input to the environment is assumed. In further work steps they will investigate the systematics of heavy metal incorporation in the shells and then deal with the suitability of the shells as a contamination archive.

The two researchers were able to use the laboratory of Dr. M. Arumugam of Annamalai University in Chidambaram (Centre of Advanced Study in Marine Biology in Parangipettai). PD. Dr. Sven Sindern has signed a MoU with Annamalai University and another one is being prepared by Dr. Linda Taft. The 2-week trip was very successful, not only with regard to the sampling situation, but also with regard to the expansion of Indo-German research cooperation.

Research Focus Water

PSP_Wasser.jpg

 

Indien 2020a (Mittel).pngWater is the most important resource of the 21st century and an essential element for the survival of human beings and ecosystems. As floods or high water, water turns out to be a life threatening risk factor.

Due to its spatial relation and the analysis of correlations between humans and environment, Geography is the principal science for developing well-founded solutions by interdisciplinary research projects.

Besides the understanding of scientific and ecosystematic processes, socio-economic and political issues are crucial for extensive discussions in geographical water science. Merging results from physical and human geographical research is essential for the definition of sustainable action strategies.

In the center of the main research area are topics and approaches, which deal with current water-related problems like lack of water, water quality, food security, and flood- and drought-crisis on a local to global level. All named problems connected with water will increase in many regions because of the global environmental change (climate and land use change, demographic development, etc.).

The main research area “Water” at the Department of Geography consists of different natural- and social sciences oriented disciplines of Geography dealing with interdisciplinary approaches to current issues at different scales of space and time. Extreme events like floods or droughts link “Water” with the research area “Risk”.

 

Objectives of the research area “Water” are:

  • Strengthen the links between the research groups within the Department of Geography as well as with other departments, faculties and associated institutes of the University.
  • Initiate joint research projects to develop approaches for dealing with the urgent questions of water availability, allocation and quality.

The research area is supposed to visualize the water related research ongoing in the Department of Geography and the University and strengthen their positions through the use of synergies. More information is available on the homepage of the Department of Geography.

GlobE: WETLANDS IN EAST AFRICA: Reconciling future food production with environmental protection

Logo Wetlands ProjektFood production in East Africa shows stagnating and even declining trends, mainly a consequence of land degradation and climate variability. In contrast, wetlands, with year-round water availability, high resource base quality and the potential to harvest several crops per year present production hotspots in an otherwise degraded landscape. Wetlands cover 40 Mio ha in East Africa with only a small share currently being used. We surmise that these areas may become the bread basket of the region. 
A consortium from Bonn-Köln-Jülich and African partners will assess the status quo of wetlands’ contribution to food security and the sustainability of current wetland uses along climatic and social gradients.

Further Completed Projects

Studying changes of sea level and water storage for coastal regions in West-Africa, using satellite and terrestrial data sets (COAST)

The project "Studying changes of sea level and water storage for coastal regions in West-Africa, using satellite and terrestrial data sets (COAST)" applies an integrative approach to research water storage and -fluxes, as well as sea level changes at the regional scale in West Africa. The project is funded by the DFG and was approved in 2015 (http://www.dfg.de/). The project focuses on the use of remote sensing datasets (such as GRACE total water storage data, SMOS soil moisture data and TRMM precipitation data, among others). Furthermore, local observations as well as results generated using distributed hydrological models are used.

 

Transregio 32: "Patterns in Soil-Vegetation-Atmosphere Systems: monitoring, modelling and data assimilation"

Subproject C1 - Spatio-temporal variability of catchment properties and their effect on water, solute, and CO2 fluxes from the micro to the mesoscale:

The cycling of energy, water and carbon through soil, vegetation and atmosphere influences the distribution and quality of life on Earth. With the rapid growth of the world population and its needs, the sustainable and efficient management of our natural resources becomes more important than ever. The Transregional Collaborative Research Centre 32 focuses on a better understanding of the processes and interdependencies within and between soil, vegetation and the atmosphere which will lead to more reliable weather and climate models and more accurate predictions for water and CO2 transport to support an improved management of natural resources.
