  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. Mapping Connectivity in the Swedish Agricultural Landscape

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : William Franzén; [2020]
    Keywords : ; GIS; Circuitscape; Structural Connectivity; Agriculture; Landscape; Perennialization; Land use;

    Abstract : The changes that Swedish agriculture has undergone during the 20th century has resulted in strongly increased productivity, but at the cost of more intensive environmental impacts. One of these is loss of biodiversity, which is driven by, e.g., usage of pesticides and loss and fragmentation of habitats. READ MORE

  3. 3. Hydrological modelling and flood risk in a data scarce country: Matola, Mozambique

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tanja Sellick; [2020]
    Keywords : hydrological modelling; flood hazard; TFM-DYN; climate change; Matola; Mozambique; data scarcity; pluvial flooding; flood risk.; Earth and Environmental Sciences;

    Abstract : Flooding is a frequent natural hazard globally that is capable of major damage to society. The hazard is especially prevalent in Mozambique, in which many flood events with negative effects have occurred. Disaster risk management and research is therefore important in the country. However, as a developing country, it is subject to data scarcity. READ MORE

  4. 4. Remote sensing-based land cover classification and change detection using Sentinel-2 data and Random Forest : A case study of Rusinga Island, Kenya

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Malena Hesping; [2020]
    Keywords : Land cover classification; post-classification change detection; Random Forest; remote sensing; Sentinel-2;

    Abstract : Healthy forests and soils are crucial for the very existence of mankind as they provide food, clean water and air, shade and protection against floods and storms. With their photosynthetic carbon storage ability, they mitigate climate change and fertilise and stabilise soils. READ MORE

  5. 5. Deep Learning for Sea-Ice Classification on Synthetic Aperture Radar (SAR) Images in Earth Observation : Classification Using Semi-Supervised Generative Adversarial Networks on Partially Labeled Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Francesco Staccone; [2020]
    Keywords : Earth Observation; Classification; Deep Learning; Convolutional NeuralNetworks; Semi-Supervised Learning; GenerativeAdversarialNetworks; Jordobservation; Klassificering; Djupinlärning; IhopveckladeNeurala Nätverk; Halvövervakad Inlärning; Generativa Fientliga Nätverk;

    Abstract : Earth Observation is the gathering of information about planet Earth’s system via Remote Sensing technologies for monitoring land cover types and their changes. Through the years, image classification techniques have been widely studied and employed to extract useful information from Earth Observation data such as satellite imagery. READ MORE
