“…The results showed that OC did not significantly vary with land use types and soil sampling depths (P = 0.2756) and (P = 0.4798) respectively but large variation existed across the various land uses and sampling depths (Table 2). Generally, OC content within the soils were considered low in agreement with Shehu et al (2018) who reported very low level of OC in some Northern Nigerian Savanna soils and Ande et al (2016) who reported less than 0.8% OC within the top 30 cm in Southern Guinea Savanna of North Central Nigeria. Bationo and Buerkert (2001) reported 0.4% as a mean concentration of organic carbon within the topsoil of an area in Sudan zone and 0.2% for the Sahel zone and further opined that the soils in the Sudano-Sahelian zone are inherently low in OC.…”

Evaluation of soil hydro-physical properties is very important in agriculture and for sustainable management of the land resources. This investigation was conducted to assess some hydro-physical properties of soils in different land use types (LUT) selected (i.e., dry upper land (UD), lowland (LL) and residential area (RA)) at 0-15cm and 15-30cm depths in Bade Local Government Area of Northeastern, Nigeria. Soils were randomly sampled at four points in each LUT and analyzed according to standard soil analysis procedures. Results of the analyses of variance showed that LL had recorded significantly higher clay content, larger soil porosities and high-water retention properties than the other LUT. Soil structural stability index (SSI) and organic carbon (OC) were below optimal range and statistically not different across the land uses. The results also indicated non-significant differences in the hydro-physical properties within the sampling depths. The coefficient of variation (CV) revealed that, slight variation (CV

“…Furthermore, the region is drained by River Niger and River Benue and their tributaries. The areas which are close to the river levees have clayey soils, while areas that are far from the river levees positions have variable and sandy soils [31]. The region has an estimated population of 29,252,408 as of 2016, according to United Nations, with about 77 percent as rural dwellers.…”

Food security is adversely affected by challenges posed by changes in land use and land cover (LULC). LULC change impacts ecosystem functions and services, leading to migration of people, particularly rural dwellers. This paper uses multispectral satellite remote sensing, net migration data, household survey, stakeholders’ meetings, Focus Group Discussions (FGD), expert interviews and yields and estimated land mass of maize, rice, groundnut, cassava, and yam to assess the extent of LULC in Niger, Kwara, and Benue states of North Central Region of Nigeria and their relevance for migration and food security. Remote sensing data for 1990, 2000, 2013, and 2020 were extracted from Landsat imageries to obtain LULC change. Household survey was conducted to validate the data obtained from Landsat imageries. The results of LULC between 1990 and 2020 show that most of the vegetation, agricultural land, and water body areas in Kwara and Benue States have been converted to built-up areas and barren land, while an increase in agricultural land and built-up areas was observed in Niger State. Our household survey, stakeholders’ meetings, and interviews showed that there was a continuous massive migration of people, particularly young farmers, to cities leaving most of the existing agricultural lands uncultivated. This was due to the losses in agricultural land and conversion of some of the other LULC classes to barren land. We conclude that if this permanent migration remains uncontrolled, it will have significantly negative future impacts on food security of Nigeria. It is recommended that the government and its sub-ordinary administrative entities invest in more reliable infrastructure and attractive living environment for the rural dwellers to reduce the rate of rural-urban migration in the study areas.
