The increasing rate of land use intensification and the rising evidence of climate change impacts raise concerns about the viability of valued non-timber forest product (NTFP)-providing trees. This calls for the assessment of the current status and future trajectories of their populations. Using population data collected from three land-use types (e.g., grazing lands, riverine areas and natural forest) in western Tigray, we evaluated the vulnerability of the multipurpose baobab tree (Adansonia d

Abstract Aim Despite mounting empirical evidence regarding the positive effects of forest structural diversity (STR DIV ) on forest functioning, the underlying biotic mechanisms and controlling abiotic factors remain poorly understood. This study provides the first assessment of the interactive effects of STR DIV and diversity in species and functional traits on aboveground biomass (AGB) in natural forests in West and East Africa. Location West and East Africa. Time period 2014–2020. Major taxa

The adverse impacts of ecosystem degradation have raised the need for forest landscape restoration (FLR) to be included in international sustainability agendas. However, the path towards successful FLR implementation faces numerous biophysical, socioeconomic and governance challenges because FLR operates within complex socioecological systems. In the present study, we review and discuss FLR challenges in the context of global environmental change. We propose a roadmap consisting of five interlin

Abstract Given recent and projected climate change, the study of adaptation and mitigation strategies which involve ecologically and economically important plant species is urgently needed. Faidherbia albida (Delile) A. Chev. is a species of both economic and ecological importance. We use 229 locational records gathered in the dry highlands of Ethiopia, nineteen environmental variables and the modelling program MaxEnt to model both the present and possible future distributions of this species. T

Despite the importance of agroforestry parkland systems for ecosystem and livelihood benefits, evidence on determinants of carbon storage in parklands remains scarce. Here, we assessed the direct and indirect influence of human management (selective harvesting of trees), abiotic factors (climate, topography, and soil) and multiple attributes of species diversity (taxonomic, functional, and structural) on aboveground carbon (AGC) stocks in 51 parklands in drylands of Benin. We used linear mixed-e

The early growth stage is critical in the response of trees to climate change and variability. It is not clear, however, what climate metrics are best to define the early-growth sensitivity in assessing adaptation strategies of young forests to climate change. Using a combination of field experiments and modelling, we assessed the climate sensitivity of two promising afforestation species, Jatropha curcas L. and Moringa oleifera Lam., by analyzing their predicted climate–growth relationships in

Abstract Land use/cover (LULC) changes have unequivocally affected biodiversity and ecosystem functioning, with enormous repercussions for human well‐being. However, the mechanistic ecological mechanisms underlying the impact of land conversion on ecosystem multifunctionality (EMF) remain insufficiently examined from the perspective of multiple biodiversity attributes in dryland regions with increasing deforestation rates. We investigated how the conversion of natural forests and savannas to agr

Climate change is expected to affect the distribution of species worldwide. Understanding how these changes impact species distribution is essential for designing conservation strategies and sustainable management approaches. Uapaca kirkiana Müll. Arg. holds significant ecological and socio-economic importance in Malawi but is highly threatened in its natural habitat. We investigated the impact of climate change on the ecological niche of U. kirkiana and identify both suitable and priority habit

Sub-Saharan Africa faces the multiple challenges of improving food security of the rapidly growing human population while halting the severe land degradation and coping with climate change impacts. Re- and afforestation of degraded lands have been recognized worldwide as cost-effective strategies to mitigate and adapt to adverse environmental changes. In this respect, the establishment phase of tree plantations is in particular decisive for the sustainability of forestation enterprises, since th
