    Sammanfattning : Sidi Bouzid, Tunisia is an inland governorate in Tunisia that has undergone a rapid agricultural and urban development since the Tunisian independence in 1952 from being a rural and largely nomadic region into a hub of irrigated agriculture. In 2010 Mohamed Bouazizi sparked the Tunisian revolution by lighting himself on fire int he city of Sidi Bouzid, with some blaming the inequality and water scarcity created by this rapid expansion in the irrigation farming as an important cause (Bayat, 2017; Malka, 2018).

  3. 2. Evaluation of Thermal Images for Detecting Leakages in District Heating Networks : A Case Study in Örebro City

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :Natalie Ekroth; [2015]
    Nyckelord :Leak detection; thermal imaging; GIS;

    Sammanfattning : Leakages in the district heating networks is a current and growing problem. To find the leakages today many district heating companies uses manual techniques that are both time consuming and insecure, the methods can leave a lot of leakages in older pipes undiscovered for a very long time.

  4. 3. Land use/ land cover change detection and quantification : a case study in eastern Sudan

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

    Författare :Yasar Arfat; [2010]
    Nyckelord :geography; physical geography; land use land cover changes; landsat MSS; TM and ETM ; Sudan; Gadarif; remote sensing; ISODATA; maximum likelihood classifier; post classification change detection; Earth and Environmental Sciences;

    Sammanfattning : Remote sensing with high temporal resolution images has become a very strong tool for monitoring the Land use/Land cover (LULC) changes. Sudan has long been experiencing intense LULC changes. These LULC changes have resulted in widespread land degradation. LÄS MER
