“…[23] reported the complete depletion of natural forest cover and increasing loss of remnant plantation forests at −0.18% km 2 /yr, attributed to excessive timber felling without reintroduction, fires, and high dependence of communities on forest lands for subsistence, as well as inadequate forest monitoring. Land cover change studies across Southwest Nigeria, including [10] and [30], emphasized direct factors like crop cultivation, lumbering/commercial logging, fuelwood and polewood extraction, and charcoal production contributing to considerable deforestation and forest degradation rates in the region. [53] further asserted that most forest reserves in the country were on the verge of disappearance.…”

“…Examples include Shasha FR [21], Okomu and Gilli-Gilli FRs [22], Ogbese FR [23], Akure FR [24], Osho FR [25], Ago-Owu FR [26], Falgore Game Reserve [27] and Onigambari FR [28]. Overall, Nigeria's forest ecosystems are experiencing massive spatiotemporal changes over the last decades [10] [27], with a 5% net annual forest loss between 2010 and 2015, which is predominantly driven by agricultural expansion, uncontrolled logging, urban expansion, fuelwood and charcoal production [23] [29] [30]. Meanwhile, projections have indicated a likelihood of further intensified forest cover decrease if the needed management practices are not established to forestall the negative trends and degradation.…”

Land use Land cover (LULC) has undergone progressive changes worldwide over the years. However, there is limited information available about these changes in Oba Hills Forest Reserve, Nigeria. The existing spatial analysis of the forest excluded important land use classes like settlements. Therefore, this study aimed at assessing the dynamics of LULC in Oba Hills Forest Reserve between 1987 and 2019. Images from Landsat 5, Landsat 7, and Landsat 8 for the years 1987, 2001, 2013, and 2019 were obtained and subjected to preprocessing and classification using the maximum likelihood algorithm, change detection, and Normalized Differential Vegetation Index (NDVI). The coordinates of specific benchmark locations and other points were acquired for ground-truthing and developing Digital Elevation Model (DEM). Three distinct LULC classes were identified: forest, bare land (including open spaces, agriculture, rocks, and grasslands), and built-up areas. The forest cover in the reserve gradually decreased from 56% in 1987 to 47% in 2019, resulting in a total area loss of 455.4 hectares. Correspondingly, the other LULC classes experienced exponential expansion. Bare land increased from 44% in 1987 to 52% in 2019, while the built-up area expanded by 57.28 hectares. These changes are attributed to prevalent anthropogenic activities such as agriculture, grazing, logging, firewood collection, and population growth within the catchment area. The declining NDVI values in the forest reserve, from 0.52 to 0.44 within the years of assessment, further substantiated the substantial loss of forest cover. The DEM and topographical map highlighted notable steep slopes and elevations of up to over 550 m above sea level (asl) within the reserve, which have implications for forest growth and dynamics.

“…In a bid to reduce the level of global warming due to deforestation and agriculture production, various ways can be practiced to mitigate climate change [12,31]. For example, research shows that the agriculture sector has the potential to contribute to climate change mitigation, which can be done through the reduction of greenhouse gas emissions while enhancing agricultural sequestration [7].…”

Like the rest of the globe, Forests in Sub-Saharan Africa (SSA) continue to play a vital role when it comes to food security from the perspective of forest function of climate regulation, water provision, and soil protection. Nevertheless, most of the recent deforestation practices in various countries indicate that the region could face severe food insecurity in the near future since there are already signs of shortage in food production. This study, therefore, examines deforestation, climate change, and food security nexus in SSA while exploring a wide range of examples of food insecurity in the region. Content analysis and a synthetic literature study were conducted using data from scientific data banks. The study links deforestation, climate change to food security while citing examples from various SSA countries such as Cameroon, Nigeria, Kenya to mention but a few. More so, the study investigates how deforestation contributes to climate change, and how such change directly affects agricultural output and hence food security.Lastly, the study discusses the various implication of deforestation in relation to food security.Ghana's independent remnant forests by 2025, following impending pressures from deforestation [6]. However, this said, this study [14] deliberately stressed the value of forests as a reliable food insecurity source being the most productive yet easily accessible resources available to rural Cameroonians.Deforestation, which is coined by the destruction of forest cover to avail land purposely for nonforest use, primarily for agriculture is an immediate trend in SSA countries. More so, in most of SSA, the popularized practice deriving from deforestation is subsistence agriculture with an annual deforestation rate of 0.7% [30]. More studies [13][14] indicate that Africa Total natural forest cover in SSA declined by 9.5% between 2000 and 2010, of which over 75% was converted into agricultural farmland. A wide range of scholars [17][18][19][20][21][22][23][24][25][26] observed that nowhere is this nexus of land clearing and degradation with hunger more pronounced than in SSA regions.Similarly, according to this study [24], many deforestation hotspots are also common hunger zones, thus therefore glaringly implicating deforestation as an issue threatening food security.Entirely, this can be related to the fact that forests offer habitats to a variety of shrub, animal and fish species commonly consumed by forest communities.

“…Fasona et al [20] observed that growing aridity in the Sahel and Sudan savannah regions had rendered significant expanses of land unsuitable for agriculture, leading to food security crisis in densely populated areas. They further predicted consequences of climate change results to a steady increase in the number of malnourished children in Nigeria.…”

The study delves into the critical issue of climate change and its detrimental impact on various regions worldwide, including Nigeria. It emphasizes the urgent need for global efforts to mitigate these effects and advocates for measures to address human activities contributing to climate dynamics. Specifically, the study empirically examines the affiliation between climate change shocks and food price inflation in Nigeria using a Nonlinear Autoregressive Distributed Lag (NARDL) approach. The dataset covers the period from January 2011 to December 2022.The empirical findings reveal a robust cointegrating relationship between climate change shocks and food price inflation in Nigeria. Notably, climate change shocks significantly contributed to rising food prices within the study period. Furthermore, the Error Correction Term (ECT), estimated at 52 percent, indicates that food price inflation adjusts by 52 percent in the current month to counteract the initial shock experienced in the previous month. The Dynamic Multiplier graph, along with a 95 percent confidence interval, demonstrates that the explanatory variables exert substantial influence on food price inflation in Nigeria during the study period. Considering these findings, the study recommends that Nigeria should transit from traditional agricultural practices to Climate-Smart Agriculture to address future needs and climate-related challenges. Additionally, the government and stakeholders should implement alternative practices such as irrigation and the replenishment of shrinking water bodies in the Sudan and Sahel savannah regions.
