The availability of freely available moderate-to-high spatial resolution (10–30 m) satellite imagery received a major boost with the recent launch Sentinel-2 sensor by European Space Agency. Together Landsat, these sensors provide scientific community wide range spatial, spectral, and temporal properties. This study compared explored synergistic use Landsat-8 data in mapping land cover (LULC) rural Burkina Faso. Specifically, contribution red-edge bands improving LULC was examined. Three...
In Africa, protected areas can play an important role in mitigating the effects of climate change through carbon sequestration but they are threatened due to increasing land degradation and deforestation (LDD). The Total Wildlife Reserve Bontioli (TWRB) Burkina Faso is one country's refuges with high biodiversity. This reserve seriously by human activities, little information available about on-site causes extent. study was carried out investigate drivers extent LDD TWRB. Household surveys,...
Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height crown size, underpin wide range ecological research-from developing testing theory on forest structure dynamics, to estimating carbon stocks their uncertainties, integrating remote sensing imagery into monitoring programmes. However, these data can be surprisingly hard come by, particularly for certain regions the world specific taxonomic groups, posing real barrier progress in fields. To overcome...
Abstract Climatic and edaphic effects are increasingly being discussed in the context of biodiversity-ecosystem functioning. Here we use data from West African semi-arid tree savannas contrasting climatic conditions (lower vs . higher mean annual precipitation-MAP temperature-MAT) to (1) determine how climate modulates species richness on aboveground carbon (AGC); (2) explore AGC relate with soil variables these conditions; (3) assess influence directly, and/or indirectly through stand...
West Africa is in general limited to rainfed agriculture. It lacks irrigation opportunities and technologies that are applied many economically developed nations. A warming climate along with an increasing population wealth has the potential further strain region's meet future food needs. In this study, we investigate Africa's hydrological increase agricultural productivity through implementation of large-scale water storage irrigation. 23-member ensemble Regional Climate Models assess...
Grain legumes and drylands cereals including chickpea (Cicer arietinum), common bean (Phaseolus vulgaris), cowpea (Vigna unguiculata), groundnut (Arachis hypogaea), lentil (Lens culinaris), pigeon pea (Cajanus cajan), soybean (Glycine max), finger millet (Eleusine coracana), pearl (Pennisetum glaucum) sorghum (Sorghum bicolor) are the leading sources of food grain in Africa South Asia. These crops can help smallholder agriculture to become more resilient, productive, profitable, but their...
Abstract Aim Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at stand level matters greatly for development of future vegetation modelling calibration remote sensing products. Nevertheless, we know little about large‐scale variation determinants in tropical allometry. In this study, explored continental scaling exponents site‐specific assessed their relationships with environmental stand‐level variables...
Abstract Aim Despite mounting empirical evidence regarding the positive effects of forest structural diversity (STR DIV ) on functioning, underlying biotic mechanisms and controlling abiotic factors remain poorly understood. This study provides first assessment interactive STR in species functional traits aboveground biomass (AGB) natural forests West East Africa. Location Time period 2014–2020. Major taxa studied Woody plants. Methods Using data from 276 plots 7993 trees 207 distributed...
Identifying the best genetic material across provenances and genotypes, particularly for vigorous seedling production, is a key aspect of domestication programs. This study aimed to (i) assess provenance tree-to-tree differences in germination performance Balanites aegyptiaca (ii) identify mother trees with seed sourcing. A total 1440 ripe fruits were collected from 36 two (Karimama Tanguieta) Benin one (Mouhoun) Burkina Faso. trial was conducted using split-plot design over 30 days....
ABSTRACT Carapa procera, Lophira lanceolata , and Pentadesma butyracea are important non‐timber forest products providing species with promising value chains of their oils. To assess whether traditional uses these sustainable, this study analysed population structure regeneration patterns in non‐protected sites. Three sites where the fruits exploited for oilseed production trade were selected each species, 135 plots 665 subplots established adults regenerations inventories, respectively. The...
ABSTRACT The role of plant diversity and biomass in ecosystem functioning management is well recognized. However, the structural drivers aboveground (AGB) their influence across savanna ecosystems remain understudied, particularly semi‐arid regions. Here, we hypothesized that (i) species richness would positively AGB vegetation strata (ii) environmental factors play a secondary compared to metrics. We tested these hypotheses using data from 160 systematically established plots (0.1 ha each)...
West African savannas are experiencing rapid land cover change that threatens biodiversity and affects ecosystem productivity through the loss of habitat biomass, carbon emissions into atmosphere exacerbating climate effects. Therefore, reducing from deforestation forest degradation in these areas is critical efforts to combat change. For such restorative actions be successful, they must grounded on a clear knowledge extent which storage soil biomass according different uses. The current...
Abstract Nazinga Game Ranch (NGR) is a reserve in Burkina Faso involving local communities for securing biodiversity through sustainable management. Yet, its ecosystems are threatened by increasing number of elephants and illegal human activities. Renowned as model wildlife participatory management, NGR has mainly been studied animal only. The aim this study was to uncover ecological effects recent land management on savanna habitats including tourism, conclude more options, use/land cover...
