1. 1. Ecosystem services from woody vegetation in East African rangelands

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Anna Linnéa Elisabeth Swärd; [2023]
   Nyckelord :dryland ecosystems; rangelands; rangelands; woody vegetation; restoration; Karamoja; West Pokot; pastoralists; agro-pastoralists; East Africa;

   Sammanfattning : 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

3. 2. Pepita de oro: How AlVelAl is building a regional regenerative agriculture transformation through social innovations

   Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

   Författare :Elissa Dickson; [2023]
   Nyckelord :regenerative agriculture; Spain; sustainability transformation; social innovation; adaptive capacity; institutions; drylands;

   Sammanfattning : Regenerative Agriculture (RA) is increasingly promoted as a sustainable agri-food solution. Agronomic studies find that RA practices (e.g. cover crops, reduced tillage, crop rotation, and agroforestry) can regulate soil moisture, sequester atmospheric carbon, enhance biodiversity, and reduce the impacts of droughts and floods.

4. 3. Assessing the impact of post-fire restoration interventions using spectral vegetation indices: A case study in El Bruc, Spain

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Bernat Dorado Guerrero; [2022]
   Nyckelord :geography; GIS; restoration intervention; drylands; monitoring; BACI; spectral vegetation indices; Earth and Environmental Sciences;

   Sammanfattning : Ecological restoration has become an increasingly used practice to revert degraded land and mitigate the effects of extreme events in vulnerable biomes such as drylands. Methods to improve the assessment of these restoration interventions are essential to ensure their success, optimize resources and identify improvement aspects for future interventions. LÄS MER

5. 4. Knowledge and Data Driven Approaches for Hydrocarbon Microseepage Characterizations: An Application of Satellite Remote Sensing

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Ali Al Farid; [2020]
   Nyckelord :Geography; Geographical Information Systems; Hydrocarbon Microseepage; PCA; Crosta; Band Ratio; MTMF; Weight of Evidence; SVM; Methane Fluxes; Remote Sensing; Satellite Image Classification; Earth Observation; Mineral Classifications; Machine Learning; Earth and Environmental Sciences;

   Sammanfattning : Methane is a potent greenhouse gas that plays a major role in climate change. Significant uncertainty exists in the estimates of emissions from natural methane sources. This uncertainty in data is one of the primary scientific challenges in climate model. LÄS MER

7. 5. Risk, Resilience and Insurance in Sudanese Pastoralism

   Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Alla Safieldin; [2019]
   Nyckelord :Climate change adaptation; Disaster risk management; Drought; Index-based livestock insurance; Pastoralism; Risk; Resilience; Sudan; Earth and Environmental Sciences;

   Sammanfattning : The nomadic pastoralists of the Sahel are often identified as a group at the frontline of global climate change. Their existence in arid and semi-arid regions and their reliance on seasonal rainfall are among the factors that contribute to their vulnerability to drought and climate shocks. LÄS MER
