“…However, storing carbon in soil benefits everyone. According to Kumar et al (2009), Adesodun and Odejim (2010), and others, it boosts soil quality, improves agronomic production, advances food security, and mitigates climate change by offsetting anthropogenic emissions. Programs for conservation and reforestation have been implemented in this scenario throughout the past three decades (Tamirat and Mekides, 2020).…”

Nowadays, climate change is a hot issue all over the world which mainly affects crop production and productivity. Thus, it causes food insecurity all over the globe mainly in Sub-Saharan African countries like Ethiopia. This paper provides a comprehensive overview bonded to the appraisal of climate change impacts on nutrition, quality, and resource use, effectiveness using climate, water, and crop yield models. The studies present that climate change models with advanced spatial resolution can be a way forward for coming climate protrusions. The variability of downfall and the adding temperature was a cause of frequent failure and shortage and had a disastrous impact on the livelihood of the people. Climate change exacerbates the enormous being burden of undernutrition. It affects food and nutrition security and undermines current sweats to reduce hunger and promote nutrition. Undernutrition in turn undermines climate adaptability and the managing strategies of vulnerable populations. Climate change is now a global miracle with growth, poverty, food security, and stability counteraccusations. Because of significant dependence on the agrarian sector for product, employment, and import earnings, Ethiopia is seriously hovered by climate change, which contributes to frequent failure, flooding, and rising average temperatures. The most vulnerable sectors to climate variability and change in the country are husbandry, water, and mortal health. Agricultural sectors are severely affected by Climate change; thus, it causes the production and productivity of animals and plants. To enhance productivity, biotechnology in breeding is therefore essential; nonetheless, optimization is needed for every crop and circumstance. While some newly released crop varieties can increase yield and improve resource use efficiency, others can produce crops on marginal land that are sufficient.

“…Soil aggregation is a good indicator of soil quality influenced by different land uses [42][43][44]. SSI below 5% indicates high impact, between 5 and 7% indicates a high risk of structural degradation, and above 7% indicates low risk of degradation [45]. Only the NF had an SSI greater than 7%, indicating that the soils of the areas under reclamation, and even the RF, present high risk of loss organic carbon and susceptibility of soil erosion.…”

Iron ore mining areas and their reclamation in Minas Gerais State, Brazil: impacts on soil physical properties

Plant cover acts to maintain the balance between soil chemical, physical, and biological attributes, as well as superficial soil protection. The aim of this study was to evaluate the impacts of iron ore mining and their reclamation on soil physical properties and soil visual quality in Fort Lauderdale Municipal Park and Serra do Curral Municipal Park, Iron Quadrangle (Quadrilátero Ferrífero), Minas Gerais State, Brazil. The evaluated areas varied in relation to the post-mining condition, natural revegetation (NR), an area with gully erosion (GA) and area under eucalyptus revegetation (ER) and native vegetation cover, rupestrian field (RF), and seasonal semi-deciduous forest (NF). The main soil physical attributes evaluated were: soil organic matter (SOM), geometric mean diameter (GMD), weighted mean diameter (WMD), bulk density (Bd), air capacity (ACb), plant-available water capacity (AWC), relative field capacity (RFC), and visual soil quality assessment. In addition to the impacts on the landscape, with removal of vegetation and soil cover, iron ore mining process impacts soil physical quality measured through porosity and aggregation properties and therefore could impact ecosystems services. Areas of iron post-mining that are not restored can develop gully erosion. NR shows high erosion risk inferred through aggregation indicators (GMD = 3.84 mm; MWD = 3.04 mm), despite similar soil organic matter content and higher plant-available water and air (NR [AWC = 0.102 m 3 m −3 ; ACb = 0.328 m 3 m −3 ], NF [AWC = 0.062 m 3 m −3 ; ACb = 0.202 m 3 m −3 ]) compared with NF (GMD = 4.77 mm; MWD = 4.56 mm). ER had similar soil structure stability compared to NF as well most of the porosity indicators, which is associated with the higher soil organic matter. Soil visual assessment alone was not able to characterize the soil physical quality, mainly in the post-mining areas, because it was designed for agricultural soils.

“…The SOC stock up to the deepest layer (60-90 cm) was found highest in horticultural lands while those values of croplands and uncultivated lands exhibited similarities which are in conformity with the findings of Vikas-Sharma et al (2014). Low vegetation cover, erosion, and overgrazing could be the main cause for lower SOC stock in the upper layers under uncultivated lands (Adesodun et al 2005) whereas increased SOC stock in the deeper layers might be due to long-term accumulation of OC through deposition of root derivatives of grasses, shrubs, and other patches of natural vegetation. The variation of C sequestration also caused by qualities of C inputs where more positive responses could be observed under fruit trees (Jia et al 2015).…”

This is a study of long-term impact of agricultural land-uses on soil organic carbon (SOC) sequestration, its depth-wise distribution among some selected carbon pools, and their contribution towards loss of C through mineralization as CO 2 to understand the present situation as well as to elucidate future strategies. Soil samples from croplands, horticultural lands, and uncultivated lands in semi-arid India (south-western Punjab) were assessed for basic physico-chemical properties, SOC, SOC stock, KMnO 4oxidizable C (KOC), particulate organic C (POC), and C mineralization (CO 2-C cum). Orchards showed highest potential to sequester carbon imparting a trend of horticulture > croplands > uncultivated lands regarding SOC and its pools. Weighted mean values showed the similar trend where croplands and uncultivated lands were mostly at par. Up to 90 cm depth orchards exhibited highest SOC stock (74.89 Mg ha −1) followed by croplands (53.87 Mg ha −1) and uncultivated lands (43.72 Mg ha −1). Decrease in C along the profile was pronounced under croplands. The studied pools were positively correlated with highest magnitude observed in between POC and SOC (r = 0.831, P = 0.01). Least positive linear relation with C mineralization was exhibited by POC particularly under horticulture, and highest C mineralization was recorded in the case of KOC under cultivation. Due to having greater POC contents which is less susceptible to mineralization loss, horticulture exhibited long-term stability of soil C than croplands. Croplands suggest faster loss of soil C for the presence of labile KOC fraction in a comparatively higher extent. Therefore, inclusion of horticultural land-use could be considered as a positive strategy to maintain the future productivity as well as sustainability of the studied area where intensive cultivation is prevailed.
