“…Urban demand for charcoal for cooking is met by tree-falling for charcoal production mainly from the Sudanian zone. It has been estimated that the demand for charcoal in sub-Saharan Africa will continue to rise in the coming decades due to increasing urban demand for charcoal (Mensah et al, 2022;Rose et al, 2022). The climatic impacts on land use land cover change, according to our analysis, are more pronounced in the Sahelian and Saharan zones with relatively harsh climatic conditions and smaller populations compared to the Guinean and Sudanian zones with mild climatic conditions and a large population.…”

The relationship between climate and land use land cover change over West Africa has often been assessed with climate simulations, although the model-based approach suffers from the limitations of climate models specifically for West Africa. In this paper, an alternative approach based on physical analysis of historical land cover data and standardized climatic indices is used to investigate climate-land interactions to establish the climatic thresholds and their corresponding land use impacts. Annualized land change intensities and the climatic indices are first estimated separately and then linked at various spatiotemporal scales. The result shows that climate-induced land cover change results from abrupt changes in climatic conditions. A regional change of (-1.0–1.0)\(℃\), (0–1.5)\(℃\),(-0.5–0.5)\(℃\), and up to \(\pm\)50 mm changes in precipitation and climatic water balance leads to (45039–52133) km2, (20935–22127) km2 and approximately 32000 km2 changes respectively, while a \(\pm\)0.5\(℃\) and \(\pm\)20 mm change represents normal climate conditions with changes below 20000 km2. Conversely, the plausible pathways through which West African land surface impacts the climate is the conversion of cropland, forest, grassland, and shrubland. The average climatic risk ranges from − 0.025 to 0.025 yr−1 while the probability of occurrence ranged variably from 0 to 0.833. The results offer the basis to re-evaluate land and climatic information necessary for improving the reliability of climate models over West Africa. For sustainable development, this work reveals the need for policy-driven interventions for efficient resource management and the prevention of degradation and deforestation in the region.

“…In Mongolia, mining has imposed a dramatic negative impact on steppes (Suzuki, 2013). The savannas of Saharan and subSaharan Africa are under pressure from agricultural expansion, mining, and wood extraction, including charcoal production (Herrmann et al, 2020;Mensah et al, 2020;Ordway et al, 2017). Due to their conversion to various land uses, rangelands in the Middle East are under pressure due to their conversion to various land uses (Mazloum et al, 2021).…”

Multiple trajectories of grassland fragmentation, degradation, and recovery in Russia's steppes

Over the 20th century, the Eurasian steppes underwent drastic land-cover changes.Much progress was made studying cropland expansion and the post-1990 (i.e., post-Soviet) agricultural land abandonment in Eurasia. However, the alteration of steppe landscapes may include other disturbances, such as oil and gas development, formal and informal roads and garbage dumps, which were not systematically documented.Considering the example of the steppe Orenburg Province in Russia, we reconstructed agricultural land-cover change dynamics using Landsat and Sentinel-2 imagery from 1990 to 2018. Furthermore, we used very high-resolution imagery and assessed the patterns and determinants of other steppe landscape anthropogenic disturbances. Our study showed that, despite steppe recovery due to widespread cropland abandonment from 1990 to 2018, the steppes, including the recovered steppe patches, underwent fragmentation due to informal roads, oil and gas development, shrub encroachment, garbage dumps and quarries, as well as abandonment of settlements and buildings. Only 6.4% of the sampled 7859 1Â1 km blocks in 2018 showing grassland extent had no documented disturbances. The mapped disturbances occurred primarily near settlements and roads, while some disturbances occurred in remote areas. Given the accessibility of steppes, our study calls for a urgent need to systematically document alternatives to agricultural land uses in the steppes of Eurasia and other parts of the global grassland biome.

“…The local economic development potential of even intermittent electricity access is substantial. Moreover, reduction in the use of domestic biomass fuels (notably charcoal) has potential respiratory health benefits, reduces risks of injury or property damage from fire, and ameliorates forest habitats from deforestation (Mensah et al, 2020). These benefits are now firmly established in the political imagination, such that expansion of grid access is prioritised as a matter of social justice for development organisations and state authorities, as well as a popular (and vote-winning) issue amongst urban and rural publics (Imami et al, 2020).…”

Among developing nations, Mozambique has set an ambitious target to achieve universal energy access by 2030 and thus meet the United Nations' Sustainable Development Goal 7 to ensure access to affordable, reliable, sustainable and modern energy for all. By the end of 2024 the government expects to double domestic electricity access to 64 per cent of the population. Yet the quantitative evaluation of electricity access rates belies challenges of energy service affordability, household budgeting, and fuel and technology availability and choice. With growing concern over issues of energy poverty and energy justice for vulnerable low-income communities, this study provides an in-depth qualitative evaluation of the lived experience of energy access and energy poverty in urban Mozambique, through household interviews in the four biggest cities in the country. There are three main findings. First, we find qualitative indicators of energy wellbeing in urban households, however this energy wellbeing is divided politically -with energy service benefits felt most strongly in municipalities governed by the dominant party: Frelimo. Second, sustainable energy transitions in urban households are limited by the low uptake of renewable energy sources. Third, despite the majority having gridconnected electricity access, many urban households continue to use non-renewable fuels (gas and charcoal) for cooking and view renewable sources, such as solar panels, as a short-term energy fix. We argue therefore that greater policy emphasis upon smallscale renewable energy investment, uptake and implementation in urban localities is needed to spur action on sustainable energy poverty alleviation.
