“…It is a serious problem in Nigeria that has greatly affected agricultural productivity and the environment. From [22], it was explained that land degradation is majorly caused by accelerated soil erosion and other underlying causes such as burning of vegetation, forest and woodland destruction, overgrazing by farm animals, low input agriculture, absence of regulations on land use, lack of knowledge about land conservation and absence of social organizational structure conducive to a suitable land use. In a review by [19], land degradation is primarily caused by overexploitation for production of fuel wood, overgrazing, overpopulation, industrial activities and poor agricultural practices.…”

Land degradation is a major challenge to agriculture in Nigeria. Soil conservation practices have been put in place to reclaim degraded landscapes. The effectiveness of these measures in improving soil properties have not been really studied in Nigeria, particularly in Uyo, Akwa Ibom State. This research assessed the effect of soil and water conservation structures (Gabions and Mattresses) in Ikot Akpan ravine on selected soil properties. A total of 12 soil samples were collected from the conserved (plots treated with gabions and mattresses) and non-conserved (plots with no treatment). Soil tests to determine soil properties were done. A one-way analysis of variance (ANOVA) statistics using a general linear model at a=0.05 was used to show significant difference exists between the two landscapes. The results showed that sand (80.84 ± 1.26%, 81.07 ± 1.90%), silt (13.70 ±3.30%, 11.41 ± 2.53%), and pH (6.51 ± 0.26) were positively affected by the conservation structure. However, bulk density (2.33± 0.27g/cc, 2.38 ± 0.16g/cc) and electrical conductivity (00.12 ± 0.02ds/m) were negatively impacted by the conservation structure. Other soil properties such as clay (7.71 ±2.54%, 7.79 ± 1.02%), available phosphorus (30.12 ±4.55mg/kg, 44.81 ± 9.28mg/kg), total nitrogen (0.05 ±0.01%, 0.05±0.02), moisture content (5.48 ±0.96%, 5.68 ± 0.85%), organic carbon (1.97 ± 0.04%, 1.95 ± 0.11%), effective cation exchange capacity (ECEC) (13.85±4.30 cmol/kg, 15.76 ± 2.06 cmol/kg) and exchangeable bases were not affected by the conservation practice. The conservation structure was very effective in controlling soil erosion and reducing soil loss. Soil conservation practices should be encouraged.

“…Okotoni (2004) corroborated the view of the World Bank report when he broadly considered environment as the totality of natural and human surrounding and activities including biophysical components and processes of the natural environment of land, water and air, including all layers of the atmosphere, all inorganic and organic matters, both living and nonliving, socio-economic components and processes of the human environment including social, economic, technological, administrative, cultural, historical, archaeological, land and its associated resources. Though, several research have revealed that land degradation has its causes (for example, Maingwa et al, (2007), it has been equally discovered that the menace inflicts external or off-site costs which also impacts harder on the society. These impacts are, however difficult to evaluate because they are indirect, non-marketed and even difficult to trace (Barbier, 1998).…”

One of the challenges that pose threats to human survival in these contemporary times is environmental degradation. The over-exploitation of natural resources is currently at an alarming rate in developing nations with an unabated population increase like Nigeria and may continue to spell hardship and discomfort if efforts are not made by all stakeholders to checkmate the trend. The rate at which the human population is increasing also needs to be checked in order to ensure sustainable availability of environmental resources for both present and unborn generations. The control is necessitated to ensure that the natural resources such as soils, water, forest, mineral resources amongst others are sustainably utilized for human survival. This review therefore examines the subject matter of degradation in the tropical environment, its remote causes, consequences in order to proffer measures for checkmating the trend. The planet Earth remains the only one in the universe that accommodates life in abundance, and so, all stakeholders in environmental management and other related professions need to put in necessary efforts through which the degradation of the Earth resources may be curtailed.

“…Northern Nigeria provides a conducive context to evaluate trade-offs between welfare and agricultural GHG emissions due to the importance of smallholder farmer production. It may be a potential "hot spot" for GHG emissions (Rufino et al 2015) because it is the most degraded region in the country (Farauta et al 2011), given the severity of the loss of soil fertility and subsequent low productivity (Maiangwa et al 2007). Furthermore, the potential trade-offs of reducing GHG emissions on smallholder farms are often unknown (Nicholson et al 2011;Thornton et al 2018).…”

This study analyses the trade-offs between welfare (measured by income) and greenhouse gas (GHG) emissions using a farm-level optimisation model that incorporates the predominant cereal (sorghum), legumes (groundnut, soybeans), livestock (cattle, goats and sheep) and trees (locust bean, camel’s foot) representative of production systems at two contrasting sites in northern Nigeria. The optimisation model maximises the value of total farm production, subject to constraints on GHG reductions of 10%, 25% and the maximum reductions that allow households to meet minimum consumption requirements. Substantive reductions in livestock and legume production would be required to achieve the maximum possible reductions from current emissions and would reduce household income by 22% and 44%, respectively. Under current production practices, reductions in GHG emissions reduce household income, which suggests the need for further research on productivity-enhancing technologies that could both enhance income and reduce GHG emissions in these production contexts.
