6. Exploring the spatial relationship between NDVI and rainfall in the semi-arid Sahel with geographically weighted regression
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The Normalized Vegetation Difference Index (NDVI) is frequently used as a surrogate for vegetation properties and is often correlated with climatic variables such as rainfall. However, studies have shown that conventional regression models used to study the spatial relationship between NDVI and rainfall are often plagued by non-stationarity and are scale dependent.

8. Investigations of a stalactite from Al Hota cave in Oman and its implications for palaeoclimatic reconstructions
University essay from Lunds universitet/Geologiska institutionenAbstract : Speleothems and other cave sediments have proven to be valuable tools for climate reconstructions. They allow to reconstruct the changes of temperatures and precipitation over time even in arid areas where other types of sedimentary archives are scarce or even non-existent. READ MORE

9. Inter-annual memory effects between soil moisture and NDVI in the Sahel
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The Sahel lies in the semi-arid zone of North Africa between the Sahara Desert to the north and the savannas and rainforest to the south. In the Sahel, the variability of vegetation growth is predominately controlled by moisture reception in the concurrent rainy season. READ MORE

10. Long Term Environmental Modelling of Soil-Water-Plant Exposed to Saline Water.
University essay from KTH/Mark- och vattenteknikAbstract : The impact of long term management strategies of irrigation with saline water in semi-arid region of Gordonia, South Africa is the highest interest to optimize water consumption, soil conservation, and crop yield for sustainable water allocations to human food production and ecosystem without irreversible damages to soil and water body. An integrated ecosystem assimilation, in shape of soil-water storage model based on physical approach for 30-year simulation run defined in form of digital ecosystem modelling with help of CoupModel tool to assemble together the most important underlying processes of soil hydraulics, irrigation demands, leaching fraction, evapotranspiration, salt transport.
