“…Grasslands are a major ecosystem, occupying one-third of the world’s terrestrial landscape, and are recognised globally for being rich in biodiversity [ 41 ]. However, grasslands are declining at an accelerated pace due to their conversion into arable land for agriculture [ 17 ]. The LULC mapping exercise revealed that 545 ha of grasslands were lost between 1990 and 2018.…”

“…Various parts of the African continent face significant pressure due to an intensified need for economic development. This now jeopardises the established protection of the considerable natural resources in these areas [ 17 ]. Therefore, concrete evidence of unsustainable LULC changes is critical, while mapping is also critical for proper planning around land-use changes and ecosystem services [ 18 ].…”

Land-use/land-cover (LULC) changes have implications for the long-term outlook of environmental processes, especially in the face of factors such as climate change. These changes can have serious consequences for humans. In this study, remote sensing and geographic information system methods were used to investigate LULC changes in a critical biodiversity area (CBA) in the northern sections of Limpopo Province in South Africa from 1990 to 2018 using data obtained from the South African National Land Cover project. In 1990, the dominant land cover comprised thickets and dense bush, followed by woodland and built-up areas, covering proportions of 40, 24 and 18% of the total land-cover area, respectively. Bare and forest areas were the least dominant classes during this time. In 2018, the dominant land cover was woodland, followed by built-up areas, comprising 71 and 20% of the total area, respectively. Subsistence agriculture is a land-cover class with a relatively higher area compared to water bodies, wetlands and other classes. Between 1990 and 2018, significant changes in land-cover were noted for thickets and dense bush, woodland, water bodies, subsistence agriculture and built-up areas. Woodland increased by over 1000 hectares (ha) per year, while thickets decreased by over 900 ha per year. Interviews were conducted with local residents to determine what they thought were the drivers behind the observed changes. According to these interviews, the drivers included deforestation, agricultural activities in wetlands, sand and gravel mining, among others. The study’s outcomes are critical for future land-use planning exercises and the long-term conservation of this CBA, an area rich in biodiversity and a strategic water source for the communities.

“…Many regions of Africa are facing rapid and profound transformation economically, socially, and environmentally a transformation that is already endangering the long-standing conservation of its substantial natural heritage and biodiversity (Mwampamba et al, 2016). Hence, the ongoing deterioration of ecosystems occurs in many regions of the continent at the expense of the well-being (Sutton et al, 2016).…”

Assessing Dynamics in the Value of Ecosystem Services in Response to Land Cover/Land Use Changes in Ethiopia, East African Rift System

Ecosystem services (ES) are essential to human well-being. Assessing dynamics of ES is crucial to shaping the concept of sustainable development and creating public understanding of the status of ES. This study proposes to quantify the change in ES value in response to Land cover/land use (LCLU) changes over the past 33 years in the Rift Valley Lakes Region of Ethiopia. A combined approach of LCLU classification and modified ES value coefficients was employed for quantifying the ES value. Results revealed that approximately USD196.04 ×10 6 (12.4%) of ES value was lost during the study period. Although cropland experienced a dramatic expansion, the total gain in ES value of the cropland was too small to balance out the overall loss. A continuous reduction in values of specific ES functions has also occurred except for food production, biological control, and pollination service function over the last three decades, indicating an apparent deterioration of the fragile Rift Valley ecosystem. Hence, to enhance the continuous supply of ES and economic development, an integrated approach to managing land and water resources is recommended. Moreover, payment for ES is also a potential remedy for ES loss at the regional and local scale.

“…In central Africa, the combined effects of mining, infrastructural development (Damania & Wheeler, 2015; Edwards et al, 2014), timber trade (Fuller et al, 2019; Malcom & Ray, 2000) and human population growth (Cordeiro et al, 2007; Mwampamba et al, 2016) are expected to have substantial impacts on landscape, land‐use viability and ecology. Bushmeat extraction (Abernethy et al, 2013; Lindsey et al, 2013; van Vliet et al, 2015; Wilkie et al, 2016) may impact mammalian distribution (Vanthomme et al, 2013; Wright et al, 2000) and associated ecosystem functioning (Babweteera & Ssekuubwa, 2017), which could reduce forests' capacity to store carbon (Morin et al, 2018) and result in degraded forest ecosystems (Vásquez‐Grandón et al, 2018).…”

Short recce transects or camera trap surveys—Short recce surveys highlighted as a useful supplement for rapid biodiversity assessments in the Republic of the Congo

et al. 2022

A rapid biodiversity assessment was conducted in the Republic of the Congo including a systematic biodiversity study (including a targeted study of mammals), implemented over two seasons. One hundred thirteen recce transects (250 m by 2 m) were undertaken over 34 days of fieldwork. A total of 19 species were detected (3 to genus level only). The encounter rate was 26.65 mammalian signs per km; no differences in numbers of signs between season appeared; however, the dry-season species accumulation pattern was higher than during wet season. Correlation analysis showed increasing density of mammals as distance away from villages, lakes and coast increased. The correlation result is deemed to highlight not only a substantial hunting pressure and avoidance of humans, but also preference for forested habitats noted to appear from 20 km distance from the coast. Using high numbers of relatively short recce transect proved a useful supplementary method for assessing mammalian diversity during rapid biodiversity assessments. Results suggest that 70 recce transects (with a minimum of eight per habitat type) would have been sufficient to yield this information.
