1. Ecosystem services from woody vegetation in East African rangelands
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Drylands cover nearly half of the Earth's land surface and are dominated by croplands and rangelands. Dryland ecosystems worldwide are affected by land degradation. Increased population pressure, climate change and unsustainable land use threaten essential ecosystem services and adversely impact people’s livelihoods and well-being. LÄS MER
2. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER
3. Ecosystem Services Based Evaluation Framework of Land-use Management Options for Dryland Salinity in the Avon Region, Western Australian Wheatbelt
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Dryland-salinity management options aim to positively influence the adverse human-induced processes which lead to salinisation of top-soil. Specifically, the processes causing dryland-salinity are rising saline groundwater table and soil erosion. LÄS MER
