“…Forest loss is on account of several factors, but boosting agricultural production is a major motive of decimating forests, which results in the loss of biodiversity (Badamasi et al 2018;Fasona et al 2020;Miyamoto 2020;FAO and UNEP 2020). Agricultural expansion is solely responsible for 70-80% of forest loss in Africa (Olorunfemi et al 2021). This underscores the significance of forest land conversion for the purpose of agricultural expansion.…”

“…It boosts livelihood opportunities and occupies 40% of the land cover (Hasan et al 2020), making agricultural land a prime land use type. Especially in least developing countries like Nigeria, increasing human population puts the agricultural enterprise under pressure to expand (Olorunfemi et al 2021). Nigeria is classified as the second of the nine countries that will account for 50% of the global population growth by 2050 (United Nations Population Division 2017).…”

“…Aside from energy use, forest land conversion is the largest contributor to CO 2 and other greenhouse gas emissions in Nigeria, considering that 60% of total emissions were on account of this conversion (Fasona et al 2020). Greenhouse gas emissions herald into rising temperature and climate change (Olorunfemi et al 2021). Reducing these emissions is central to mitigating climate change.…”

“…Climate change is probably the greatest global environmental threat of our time, making international accords to resolve to mitigate the same by halting the global CO 2 emissions to net zero by 2050 (Ayompe et al 2021). One-third of the greenhouse gas emission is on account of land use change cum agricultural activities in sub-Saharan Africa (Olorunfemi et al 2021). The preservation of Africa's forests has been identified as a means of lightening the burden of climate change in the Reducing Emissions from Deforestation and Degradation (REDD) programmes (Olorunfemi et al 2021).…”

Natural and forest-rich ecosystems are determinants of environmental sustainability, which are threatened by forest land conversion for agricultural purposes, especially in less-developed contexts. Moreover, human behaviour is central to achieving the much desired ecologically balanced environment. Hence, a partly novel model informed by the theory of planned behaviour was used in the examination of forest land conversion for agricultural purposes. The study design was a cross-sectional survey targeted at a group of farmers of southwestern Nigeria. Data were collected using a structured questionnaire among 320 randomly selected crop farmers. Independent samples t test and one-way analysis of variance (ANOVA) were used to test the significance of difference in respondents' forest conversion behaviour across subgroups of gender and age/education, respectively. Stepwise multiple linear regression was used to identify the determinants of forest conversion behaviour. Results showed that 87.8% of respondents had ever engaged in forest conversion. Gender and education had no significant effect on forest conversion behaviour (p > 0.05), but age did (p < 0.05). Attitude was the best determinant (β = 0.289, r = 0.510, R 2 = 0.260, p < 0.001), subjective norm was better (β = 0.257, r = 0.496, R 2 = 0.055, p < 0.001), while perceived behavioural control was good (β = 0.131, r = 0.398, p < 0.001, R 2 = 0.012, p < 0.005). The three variables correlated with intention by a degree of 57.2% (multiple R = 0.572), while they explained 32.7% of the variance in intention (R 2 =0.327). Intention was also found to be a significant determinant of behaviour (β = 0.222, r = 0.222, R 2 = 0.049, p < 0.001). Middle age predisposes to, whereas younger and older age protects against greater extent of forest conversion. The partly novel model derived from the theory of planned behaviour proves the likely viability of the pursuit of socio-psychologically predicated interventions to enthrone forest conservation.

“…Tropical forests play an essential role in the global carbon cycle. They store approximately 40-50% of the total carbon stocks in terrestrial ecosystems of the world, account for around 30-40% of global net primary production [1][2][3], are currently under threat due to deforestation [4]. Tropical montane forest's (TMFs) above-ground live biomass carbon (AGC) varies along the elevation gradient and with soil physico-chemical properties [1] but is not tested in lowland coastal forests (LCF).…”

The East-African lowland coastal forest (LCF) is one of Africa’s centres of species endemism, representing an important biodiversity hotspot. However, deforestation and forest degradation due to the high demand for fuelwood has reduced forest cover and diversity, with unknown consequences for associated terrestrial carbon stocks in this LCF system. Our study assessed spatio-temporal land use and land cover changes (LULC) in 1998, 2008, 2018 in the LCF ecosystem, Tanzania. In addition, we conducted a forest inventory survey and calculated associated carbon storage for this LCF ecosystem. Using methods of land use change evaluation plug-in in QGIS based on historical land use data, we modelled carbon stock trends post-2018 in associated LULC for the future 30 years. We found that agriculture and grassland combined increased substantially by 21.5% between the year 1998 and 2018 while forest cover declined by 29%. Furthermore, forest above-ground live biomass carbon (AGC) was 2.4 times higher in forest than in the bushland, 5.8 times in the agriculture with scattered settlement and 14.8 times higher than in the grassland. The estimated average soil organic carbon (SOC) was 76.03 ± 6.26 t/ha across the entire study area. Our study helps to identify land use impacts on ecosystem services, supporting decision-makers in future land-use planning.

The climate and land use change nexus: Implications for designing adaptation and conservation investment strategies in Sub‐Saharan Africa

Climate change and land use change are two global and interacting forces of change that have wide‐reaching effects on socio‐ecological systems. Despite their interconnectedness, the two are mostly considered separately in investment programs. Therefore, without an integrated systemic approach that considers these interactions, we will fail to achieve the ambitions to deliver on the Sustainable Development Goals. By integrating the Driver‐Pressure‐State‐Impact‐Response framework and the System of Environmental‐Economic Accounts Ecosystem Accounting, this paper assesses how the interlinkages between climate change and land use change can be jointly considered in the design of climate adaptation and ecosystem conservation investments. The analysis points to the following priorities for interventions in an integrated approach: forest conservation, protection of peatlands, climate‐smart agriculture, and restoration of degraded lands. The paper furthermore suggests a set of systemic investment principles that can contribute to capital allocation for climate adaptation and conservation.
