1. Evaluation of Modern Irrigation Techniques with Brackish Water
Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER
2. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements
Sammanfattning : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. LÄS MER
3. Carbon stock and fluxes in Nyungwe forest and Ruhande Arboretum in Rwanda
Sammanfattning : Conservation and sequestration of carbon in forest ecosystems are potential strategies to reduce or stabilize the atmospheric greenhouse gas concentrations and mitigate climate change. Estimating the... LÄS MER
4. Water harvesting for resilience building in the Sahel : on-farm supplemental irrigation and soil fertility management for dry spell mitigation of sorghum
Sammanfattning : .... LÄS MER
5. Evaporation and Heat-flux Aggregation in Heterogeneous Boreal Landscapes
Sammanfattning : The boreal forests represent 8 % of all forested areas on the earth and have a significant role in the control of greenhouse gases and an impact on global climate change. The main objective of this thesis is to increase the understanding of how evaporation and heat-flux processes in the boreal forest zone are affecting the regional and global climate. LÄS MER
