“…Few studies in Ethiopia focused mainly on SOC distribution using GIS and RS (Vågen et al 2012(Vågen et al , 2013. However, majority of the studies involving RS and GIS focused basically on land use cover/ change (Asmamaw et al 2011;Kindu et al 2013;Hailemariam et al 2016;Demissie et al 2017;Birhane et al 2019), land suitability/capability for crop production (Kahsay et al 2018;Yohannes and Soromessa 2019), and erosion or soil loss modeling (Mellerowicz et al 1994;Israel 2011;Gebreyesus et al 2014;Woldemariam et al 2018). Integration of GIS and RS in SOC studies can increase our power of precise prediction in terms of SOC storage and dynamics under different land use types in modulable scenarios of changing climate.…”

Background: In the face of climate change and global warming, scientists globally are striving for effective techniques on how best to sequester carbon in order to reduce global warming and achieve environmental sustainability. This paper reviews the available literature on the influence of various land use changes on gains and/ or losses of soil carbon (C) stocks in Ethiopia. Results: Our review indicated that 33.3% of the studies reported soil organic carbon (SOC) concentration, 13.9% reported only SOC stock while 52.8% reported both SOC concentration and stock. Studies focusing on 0-30 cm only were 44%, other studies extending up to 40 to 100 cm were 50%, and studies extending to more than 100 cm accounted for 2.8% while studies without any depth specification accounted for 2.8%. Irrespective of soil type, C stocks in the top soil (0-30 cm) were found to be higher than at subsoil depths. Even though there is significant improvement in C sequestration in exclosures and community forests, the level of C sequestered is still below that of church forests. Conclusion: Conversion of native forest to other land uses resulted in a significant decrease in the SOC stocks across Ethiopia. Absence of long-term field trials and non-existence of SOC database are among the major drawbacks of SOC studies in Ethiopia identified in this review. With better management practices, it is possible to restore depleted C concentrations and stocks even in degraded lands and to conserve C in more pristine lands across the rugged landscapes of Ethiopia.

“…The combined influence of climate and soil characteristics on crop production in sub-Sahara Africa has been appraised 6,9,11,14,15,17,18 . Our results suggest that climatic conditions exert the most limiting effects on cassava production in the semi-arid region of Nigeria.…”

To investigate the optimal cultivation conditions for cassava cultivar (TMS98/0505) in Nigeria, we employed agro-ecological zoning to delineate the cultivated lands. Using GiS-based multi-criteria analysis, we researched the influence of some meteorological and soil parameters on the clone cultivation. From the multiple-parameter climato-edaphic zoning map, an average yield of 26 t ha −1 was estimated. The dry Rainforest and southern Guinea Savanna account for 80% of the favorable zones. However, with irrigation, the cultivar would yield optimally in the northern marginal zones. Further, the significant climatic parameters are sunshine hour (t = 3.292, α = 0.0064) and rainfall (t = 2.100, α = 0.0575). Thus, the potentials of a location for cassava cultivation in Nigeria largely depend on the soil conditions, sunshine hour, and rainfall. Generally, the cassava yield correlates strongly (+0.88) with the suitability map. Considering future climate variability based on the annual rainfall data, we projected an average annual rainfall range of 565-3,193 mm between 2070 and 2099. Likewise, the projected range of daily temperature for 2046-2100 is 24.57-31.94 °C. Consequently, with currently allotted farmlands, nigeria can double her current cassava production through soil fertility enhancement and irrigation.

“…According to [50] physical soil properties mainly soil texture was the limiting factor for wheat; maize production was affected by low humidity sunshine hour, and soil salinity and alkalinity [46]. Slope gradient, altitude, temperature, length of growing period, available water capacity, total nitrogen, available phosphorus and soil organic carbon were found the main limiting factors affected cultivation of sorghum crop in northern semi-arid Ethiopia [51].…”

The natural resources are becoming scanty in developing country like Ethiopia to support over increased human population without deprivation, scientific approach of land suitability is important to make a proper decision for sustainable agricultural development and maximizing the best use of the land resources. With the deliberation of Rainfed conditions of maize, sorghum and wheat, land suitability evaluation was carried out at Bilate Alaba Subwatershed. Uses of maximum limitation and parametric (Storie and Square root) were applied for the determination of land suitability categories of land characteristics. The result showed that climate is highly suitable (S1) for maize whereas moderately suitable (S2) for sorghum and wheat. From total sub-watershed, 2.45% is marginally suitable (S3) for wheat and 97.55% is moderately suitable (S2) for maize and sorghum production using FAO land evaluation method whereas offering Storie method, 14.75% of sub-watershed is marginally suitable (S3) for sorghum and wheat, 85.25% is moderately suitable (S2) for sorghum and wheat cultivation. Considering maize production under rain-fed conditions, all mapping units were moderately suitable (S2). Parametric Square root result revealed that four soil mapping units were moderately suitable (S2) for maize, wheat and sorghum crops in the sub-watershed. Soil fertility (phosphorus and nitrogen), moisture stress and erosion hazard were the most limiting factors in the sub-watershed. Soil management practices may recover soil fertility with the application of animal manures and household wastes for nitrogen and phosphorus limitations, proper natural resource protection practice to cut the effects of erosion due to topographic features.
