National Water Conference on Status and Future Directions of Water Research in Sri Lanka, BMICH, Colombo, Sri Lanka, 4-6 November 1998. Session 4: Participatory management of irrigation; Session 5: Water resource data; Session 6: Managing water quality

The restoration of vegetation in abandoned farmlands is an effective approach to control soil erosion on the Chinese Loess Plateau. However, few studies have investigated the effect of natural restoration age on the infiltration patterns and preferential flow in soil layers. This study examined the effect of the temporal variations in the degree of preferential flow and their contribution on the total infiltration in abandoned farmlands restored with different vegetation communities.

More than one million people across Phnom Penh are facing the risk of increased flooding and over one thousand more families are at risk of evictions, loss of income and food insecurity as the ING City project and other unsustainable developments destroy the Tompoun/Cheung Ek wetlands in the capital’s south.

The conciliation between different issues such as agriculture production, biodiversity conservation and water management remains unsolved in many places in the world. As a striking example, the wet grasslands of the Marais Poitevin region (France) presents many obstacles against the integration of these issues, especially in terms of public policy design.

How can wetland management better take into account climate uncertainty, considering the risks posed to the important services wetlands provide? Ritesh Kumar of Wetlands International --South Asia explains that climate change and environmental impacts are affecting the livelihoods of hundreds of thousands of people that rely on wetland services provided by Chilika Lagoon in India. The project team is working with local government authorities to identify strategies for improving community resilience to such changes.

The wetlands around the estuaries of Ogun River and its environs in Ikorodu/Kosofe areas of Lagos State remain unprotected. 60 per cent of Lagos metropolis was originally natural wetlands. This study tackles the quantification of land use/landcover (especially wetlands), causes, land use dynamics and the health implications through direct observations using remote sensing, surveys, disease vector studies, nutritional supply studies and GIS modelling within an ecosystem approach.

This study analyzed and evaluated the changes that occurred in two coastal wetlands, characterized by complex and fragmented landscape patterns, in Southern Italy, which were monitored over a period of seven years from 2007 to 2014. Furthermore, the performances of two Land Cover (LC) and habitat taxonomies, compared for their suitability in mapping the identified changes, were assessed. A post-mapping method was adopted to detect the habitat/LC changes that occurred in the study period.

Peatlands are the “kidneys” of river basins. However, intensification of agriculture and forestry in Europe has resulted in the degradation of peatlands and their biodiversity (i.e., species, habitats and processes in ecosystems), thus impairing water retention, nutrient filtration, and carbon capture. Restoration of peatlands requires assessment of patterns and processes, and spatial planning. To support strategic planning of protection, management, and restoration of peatlands, we assessed the conservation status of three peatland types within the trans-border Neman River basin.

Commercial wetlands can contribute to different policy objectives simultaneously. The aim of this study is to investigate the opinion of the Dutch population with respect to commercial wetlands. The commercial wetland functions valued the most by the Dutch population are water treatment and water storage

Abstract Biodiversity in freshwater ecosystems – rivers, lakes and wetlands – is undergoing rapid global decline. Major drivers are land use change, eutrophication, hydrological disturbance, climate change, overexploitation and invasive species. We developed a global model for assessing the dominant human impacts on inland aquatic biodiversity. The system consists of a biodiversity model, named GLOBIO-Aquatic, that is embedded in the IMAGE model framework, i.e.
