Reconstructing Indigenous Landscapes
Colonial land reforms strip down Indigenous tenure systems globally, yet the spatial scale of this transformation remains poorly quantified. Southern Africa's Bokoni region offers a critical case study where qualitative research has long argued for intensive pre-colonial farming, but quantitative evidence has been absent. This study integrates LiDAR, GIS, archival surveys, and cadastral records to reconstruct pre-colonial settlement patterns in S…
Preliminary Insights into Economic Well-Being from a Geospatial Perspective
Economic well-being is essential for assessing sustainability of human settlement in urbanizing regions; however, the geographic factors linking settlement characteristics to residents’ well-being remain underexplored, particularly in counties in China undergoing urban–rural transformation. In this study, six representative Chinese counties (Yanshou, Wafangdian, Bazhou, Yugan, Yongsheng, and Raoping) with varying urbanization levels are investiga…
Fairly assessing nighttime urban cooling performance with a novel satellite-based index
Can nighttime light proxy comprehensive economic well-being? Evidence from China
Analysing four decades of urban growth in Greater Khartoum, Sudan, using Earth observation data and Google Earth Engine
Rapid urbanisation associated with population growth and economic development is a key driver of changes in local and global land use and land cover (LULC). Monitoring and modelling changes that occur in LULC are crucial for promoting sustainable urban development and advancing humankind. Remote sensing has been applied worldwide to map and monitor LULC changes, although mapping of the urbanisation of Khartoum (Sudan) has not yet been done. This …
How Hydrological Extremes Affect the Chlorophyll-a Concentration in Inland Water in Jiujiang City, China
From 2020 to 2022, hydrological extremes such as severe floods and droughts occurred successively in Jiujiang city, Poyang Lake Basin, posing a threat to regional water quality safety. The chlorophyll-a (Chl-a) concentration is a key indicator of river eutrophication. Until now, there has been a lack of empirical research exploring the Chl-a trend in inland water in Jiujiang in the context of hydrological extremes. In this study, Sentinel-2 satel…
Urbanisation in Sub-Saharan Cities and the Implications for Urban Agriculture
Urbanisation is the process whereby cities are transformed into large sprawling areas. Urbanisation combined with a continuous increase in population makes food security crucial for sustainable development. Urbanisation poses a threat to agricultural land use within built-up and peri-urban areas. It has resulted in the rapid disappearance and/or total change of agricultural farmland in urban and peri-urban areas. To monitor the changes in agricul…
Adapting peri-urban agriculture to climate change in Bulawayo, Zimbabwe
Peri-urban agriculture plays a critical role in sustaining food security and livelihoods in urban communities. In spite of the critical role it plays in food security, peri-urban agriculture has not received adequate attention with regards to its interface with climate change in Zimbabwe. Using a sample of thirty peri-urban plots selected through snowballing, this study investigated the farmers’ perceived effects of climate change on peri-urban a…
A critical review of the impact of South Africa’s mine closure policy and the winding-up process of mining companies
Background: Most mining operations are viable for a period of 30 years, depending on the mineral extracted and the available reserves. Whilst the expectation is that mines will continue uninterrupted until the planned period is complete, unscheduled closure can occur. Sudden and unplanned mine closure can result in immediate environmental and social impacts. In South Africa, the challenges of mine closure are exacerbated by unexpected sudden clos…
Assessing the Effects of Land Use on Surface Water Quality in the Lower uMfolozi Floodplain System, South Africa
This study investigated the impacts of cultivation on water and soil quality in the lower uMfolozi floodplain system in KwaZulu-Natal province, South Africa. We did this by assessing seasonal variations in purposefully selected water and soil properties in these two land-use systems. The observed values were statistically analysed by performing Student's paired t -tests to determine seasonal trends in these variables. Results revealed significant…
Climate change adaptation by subsistence and smallholder farmers
The unprecedented challenges posed by climate change necessitate agricultural adaptation by farmers, especially in the regions of Asia, where rain-fed agriculture is the principal source of food production. Studying adaptation not only assists in knowing how farmers are dealing with the repercussions of climate change, but also provides the baseline for the planned interventions which are essential in this era of human-instigated climate change. …
Narrative of governance crisis in Nigeria
From the resource curse perspective, this article investigated how Tunde Kelani’s twin-movies, Saworoide and Agogo-Èèwò, explored the vulnerability of leaders in natural-resource dependent state to corrupt practices, leading ultimately to governance crisis. Textual and mythical representations in the movies are critically analysed to explain the significance of tackling governance crises during the leadership-making process. Significantly, the ar…
A survey of problem weeds of sorghum and their management in two sorghum-producing districts of Zimbabwe
Sorghum is an important staple food crop in dry areas of Zimbabwe but yields are reduced due to inefficient weed management strategies that largely rely on hand weeding. A study to establish weeds associated with sorghum and their management was conducted in two sorghum-growing districts, Insiza and Chipinge, during the 2016/17 cropping season. Physical weed sampling in farmers’ fields was done to identify weeds infesting sorghum. A questionnaire…
Evaluating the capability of Worldview-2 imagery for mapping alien tree species in a heterogeneous urban environment
Street trees in urban planning have a long history as providers of an amicable environment for urban dwellers. Nevertheless, street trees are not always without a challenge, their ecosystem disservices include, inter alia, cracking pavements and foundations due to wandering tree roots that destroy concrete or asphalt surfaces. Thus, effective mapping of street trees assists in planning a suitable urban environment to improve city life. The tradit…
Roles of indigenous women in forest conservation
The roles indigenous women play in forest conservation represent the spaces allocated by society on the basis of their gender. The study employs a comparative analysis of two indigenous communities in Nueva Ecija in the Philippines to describe the role of indigenous women in forest conservation and how the intersectionality of gender, ethnicity, and traditional knowledge creates an impact on forest conservation. The theory of Eco-feminism, mixed …
Quantifying spatial-temporal changes of aboveground carbon stocks using Landsat time series data
There is a need for accurate reporting of the second-growth forest in accounting for the contribution of secondary forests to achieving global carbon sequestration strategies. This study develops a model relating aboveground live biomass (AGLB) to Landsat reflectance measurements, and this method is used on multi spatial-temporal Landsat data (1998, 2001, 2004, 2011 and 2016) to assess changes in Miombo woodlands in Zambia. Results showed that th…
Dust Deposition Impacts at a Liquidated Gold Mine Village
The windy season brings numerous community complaints for gold mining companies situated in the Witwatersrand due to windblown dust from partially rehabilitated tailings storage facilities (TSFs). For communities encroaching onto TSFs, windblown dust is perceived as a health hazard and an environmental challenge. In a study conducted in 2017 by the Lawyers for Human Rights, the community of a gold mine village perceived tailings storage facility …
