  1. 1. 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 ekosystemvetenskap

    Author : Malin Ahlbäck; [2020]
    Keywords : Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Abstract : 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

  2. 2. Increasing crop yields under climate change scenarios in Nigeria

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Imogen O'Keefe; [2020]
    Keywords : Physical Geography; Agriculture; Climate Change; Crop Yields and Management Strategies; Earth and Environmental Sciences;

    Abstract : Climate change is projected to cause unprecedented levels of global change and it will alter the ways in which humans currently rely on getting essential resources such as food. Africa is considered to be the most vulnerable continent to this change, with many countries that have low economic stability and insecure food sources a change to the way resources can be accessed could be detrimental to the population.

  3. 3. Evaluation of water stress mapping methods in vineyards using airborne thermal imaging

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alon Zuta; [2020]
    Keywords : Geography; Geographical information systems; GIS; Remote sensing; Cover crop; Thermal imaging; Spatial variability; vineyards; interpolation; water stress index; CWSI; Ig; stem water potential; UAV; Rheingau; Interpolation.; Agriculture and Food Sciences; Biology and Life Sciences; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : With low cost and high efficiency, use of airborne infrared thermography imaging from an unmanned aerial vehicle (UAV) has become a widely used technique to measure plant water stress. With that, the use of UAV mounted thermal camera as a precision agriculture technique to map crop water stress is not trivial and its success is depended on variety of factors which are still needed to be studied and understood.

  4. 4. The role of groundwater in the inundation of a river-connected floodplain : case study of the river Silverån in southeast Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Stina Bång; [2019]
    Keywords : Groundwater flooding; Groundwater modeling; Flood modeling;

    Abstract : Fluvial flooding has long been recognized as one of the most frequently occurring natural disasters worldwide, with consequences as large economic losses from damages on infrastructure and agriculture, as well as severe impacts on human health. A less known and explored type of flooding is groundwater flooding. READ MORE
