1. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California
University essay from KTH/GeoinformatikAbstract : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.

2. Assessing the Impacts of Climate Change and Water Scarcity on Agricultural Practices in Kenya -Implications for Adaptation Strategies
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Like other African countries, Kenya’ economy and food security is heavily dependent on agriculture. Climate change has led to variability in temperature and precipitation, and extreme weather events such as droughts and floods, all of which can significantly impact crop productivity and food security in the long-term.

3. Using NDVI Time-Series to Examine Post-fire Vegetation Recovery in California
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Over the past couple of decades, fires have experienced changes on a global scale. These changing fire regimes point to an alarming direction where fire-dependent ecosystems are experiencing a decline in burned area, while fire-independent ecosystems are experiencing an increase.

4. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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. READ MORE

5. Understanding discourses on technological interventions to tackle soil salinity : a case study from Khuzestan, Iran
University essay from SLU/Dept. of Urban and Rural DevelopmentAbstract : Soil salinity is an environmental hazard in arid and semi-arid regions in the world, diminishing crops growth and, hence, affecting agricultural production. One scientifically accepted solution to contrast the problem is the practice of leaching, consisting in the application of an extra amount of water, in addition to that used for irrigation, which can remove salts from the root zone, washed away through drainage.
