Introduction
Situated at the intersection of geoinformatics, environmental change and sustainability, my research assesses impacts of multidecadal land system change, incl. land degradation at multi scales. Working in temperate humid, tropical rainforests, and dryland regions, methods developed generate and validate remote sensing-based Land Degradation Neutrality metrics at national and landscape levels. Currently examining how land use change affects the resilience of smallholder food production systems.

Full-text available
This study's focus is on Palapye, a predominantly dryland agricultural but urbanising region in eastern Botswana. Maps of ten land use-land cover (LULC) categories at three time points (1986, 2000, and 2014) were produced based on the ISO 19144 land cover classification scheme. Land change intensities were examined at the time interval, category an...

Limiting global warming to 1.5 °C and 2.0 °C above pre-industrial levels has been proposed as a way to reduce the impacts of climate change globally. Formulating reliable policies to adapt to these warming levels requires an understanding of the impacts at regional and national scales. The present study examines the potential impacts of the differe...

Achieving land degradation neutrality (LDN) has been proposed to stem the loss of land resources globally. To date, LDN operationalization at country level has remained a challenge both from a policy and science perspective. Using an approach incorporating cloud‐based geospatial computing with machine learning, national level datasets of land cover...

Drought severity and impact assessments are necessary to effectively monitor droughts in semi-arid contexts. However, little is known about the influence land use-land cover (LULC) has-in terms of the differences in annual sizes and configurations-on drought effects. Coupling remote sensing and Geographic Information System techniques, drought evol...

Agricultural land area is increasing globally despite the loss of productive agricultural lands in some world regions. We examine the case of Africa where the knowledge about major agricultural land transitions and the impacts on the quality of land is still very limited. A comprehensive assessment of change in agricultural landscapes was conducted...

Africa stands to gain from Earth Observation (EO) science, products and applications. However, its use and application remain below potential on the continent. This article examines how EO can better serve the needs of African users. First, we argue that a successful uptake of EO services is conditional on understanding the African context and matc...

Large exports of land-based contaminants to the ocean exacerbate the effects of climate change, pollute ocean waters, disrupt biogeochemical cycles, harm marine organisms, and consequently jeopardise food security and the livelihoods of ocean-dependent communities. The Canary Current Large Marine Ecosystem (CCLME) is characterised by a mix of the A...
Article
Full-text available
Land use-land cover (LULC) association with land surface temperature (LST) is well known. Knowledge about land change effects on LST in urbanizing African drylands is very limited. We examined LST and vegetation variations in semi-arid Gaborone (Botswana's capital) using MODIS daytime and night-time LST (DNLST), and Normalized Difference Vegetation...

The use of geographic information is increasing as applications become more diverse. In turn, this is stimulating the need to share geographic information data, since individuals or organisations cannot satisfy all their data needs alone. Consequently, there is a growing dependence on others to obtain the full suite of data needed to carry out thei...

There is a dearth of knowledge about changing land systems in urbanizing regions, particularly small and mid-sized cities (SMCs). Yet projected urban growth is expected to occur mostly in SMCs. This research seeks to link patterns with processes to better understand the patterns and factors driving land change and interactions in SMCs. This contributes to understanding the environment impacts of peri-urbanization and generates projections of future LULC as input for modelling soil loss, runoff, soil C stock, etc.

Vegetation degradation is one type of land degradation that is common in drylands. Using a comprehensive definition of land degradation comprising physical, chemical and biological degradation types and indicators, degradation is assessed and mapped in the dryland agro-pastoral regions of Eastern Botswana. We combine the use of qualitative and quantitative data from methods including satellite image analysis of land feature change, GPS, lab analysis of soil, vegetation and water samples, questionnaire survey of land users, semi-structured interviews, participant observation, and climate data. This approach is needed as land degradation is driven by both biophysical and anthropogenic factors due to the sensitivity of semi-arid contexts to changing conditions.
