80% of arable land in Africa has low soil fertility and suffers from physical problems. Additionally, significant amounts nutrients are lost every year due to unsustainable management practices. This is partially the result insufficient use knowledge. To help bridge information gap Africa, Soil Information Service (AfSIS) project was established 2008. Over period 2008–2014, AfSIS compiled two point data sets: Profiles (legacy) database Sentinel Site database. These sets contain over 28...
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...
There is a need for up-to-date assessments and maps of soil properties land health at scales relevant decision-making management, including that are dynamic hence change in response to management. Also, there approaches mapping capture the ever increasing effects humans having on environment general specifically worldwide. In this paper, we develop models digital based remote sensing data from Moderate Resolution Imaging Spectroradiometer (MODIS) platform Africa. The article presents organic...
Abstract Aim Macroinvertebrates comprise a highly diverse set of taxa with great potential as indicators soil quality. Communities were sampled at 3,694 sites distributed world‐wide. We aimed to analyse the patterns abundance, composition and network characteristics their relationships latitude, mean annual temperature rainfall, land cover, texture agricultural practices. Location Sites are in 41 countries, ranging from 55° S 57° N 0 4,000 m elevation, rainfall 500 >3,000 mm temperatures...
Abstract Soil fauna activities are probably more important than currently acknowledged in determining individual plant response to stresses and overall diversity. Here we demonstrate that the positive effect of earthworms on rice could be result a systemic physiology. Moreover, this improve tolerance stressors such as parasitic nematodes. In controlled experiment, an 82% decrease production infested plants was suppressed when were present. Earthworms had no direct nematode population size....
Full-sun cocoa farming is currently the most widespread cultivation system in humid and sub-humid Côte d'Ivoire. Higher short-term yields from increasing surfaces under this have contributed to country being ranked as top producer world. However negative consequences including biodiversity loss, soil fertility depletion quality degradation associated with system, incredibly received so less attention that type magnitude of such agro-ecological within current context climate change are worth...
A thorough understanding of the variation in total soil element concentrations is important especially Sub-Saharan Africa (SSA) contexts for agricultural and environmental management at large scale. Fingerprinting elemental composition may form a useful basis evaluating soils way that relates to soil-forming factors inherent functional properties. The objectives this paper are quantify proportion variability by X-ray fluorescence (TXRF) method 1074 samples from Soil Information Service...
1 Stable nitrogen (N) isotope has been widely used to disentangle food webs and infer trophic positions of organisms based on an assumption that the stepwise enrichment occurs along levels. The 15N in soil with diet humification also reported, but underlying mechanism not fully examined. 2 To examine effect 15N, we estimated stable N ratios ages earthworms termites. These feed organic matter various degrees humification, ranging from undecomposed plant materials humified (soil matter), a...
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 Although soil degradation is a major threat to food security and carbon sequestration, our knowledge of the spatial extent problem its drivers very limited in Southern Africa. Therefore, this study aimed quantify risk structural determine variation stoichiometry nutrient limitations with land use categories (LUCs) climatic zones. Using data on clay, silt, organic (SOC), total nitrogen (N), available phosphorus (P), sulfur (S) concentrations collected from 4,468 plots 29 sites across...
Food security is the topmost priority on global agenda. Accurate agricultural statistics (i.e., cropped area) are essential for decision making and developing appropriate programs to achieve food security. However, derivation of these statistics, especially in countries, fraught with many challenges including financial, logistical human capacity limitations. This study investigated use fractional cover approaches mapping cropland area heterogeneous landscape West Africa. Discrete areas...
The success of terrestrial carbon sequestration projects for rural development in sub-Saharan Africa lies the (i) involvement local populations selection woody species, which represent biological assets they use to meet their daily needs, and (ii) information about potential these species store carbon. Although latter is a key prerequisite, there very little available. To help fill this gap, present study was undertaken four pilot villages (Kou, Dao, Vrassan Cassou) Ziro Province,...

Furthermore, cocoa agroforestry one most effective nature-based solutions address global change including land degradation, nutrient depletion, climate change, biodiversity loss, food nutrition insecurity, rural poverty current supply chain issues.
