6. A systems approach to ice loads on concrete dams
Sammanfattning : Dams are mainly used for the storage of water to electricity production and irrigation, or for river regulation. Continuous work to assure a high dam safety level is a prerequisite to minimize the risk for the uncontrolled release of water. LÄS MER
7. Decentralizing hydraulic society : Actor responses to institutional arrangements in Vietnam
Sammanfattning : Irrigation decentralization has been launched worldwide with high expectations of improved governance, efficiency, and productivity through democratic processes. However, there is widespread recognition that decentralization is, in reality, unlikely to bring about these positive outcomes. LÄS MER
8. Large-Scale Land Acquisitions as a Driver of Socio-Environmental Change : From the Pixel to the Globe
Sammanfattning : A major challenge of our time is to sustainably produce food and other goods for a growing global population, without putting additional pressures on land and water resources and local people’s quality of life. Large-scale agriculture has brought many benefits to humanity in terms of food production but has also caused multiple sustainability challenges, including land and water degradation, deforestation, and biodiversity loss in areas of production.

9. Pathways to future cropland : Assessing uncertainties in socio-economic processes by applying a global land-use model
Sammanfattning : Global agricultural production almost tripled within the last five decades. The production increase wasbased on expanding cropland and pastures, as well as the intensification of agriculture, including increased use ofhigh yielding crop varieties, machinery, irrigation, artificial fertilisers, and pesticides.

10. Landslide of contaminated soil into rivers: Environmental impacts and risks
Sammanfattning : Landslide risk assessments and environmental risk assessments are routinely carried out in many countries exposed to landslide hazards and/or contaminated soil hazards, but separately from each other. By combining results from different types of risk assessments and superimposing the results, possible multi-hazards may be revealed, which is not the case when the results are only displayed independently.
