“…Similarly, the northern Guinea zone (NGZ) is characterized by the presence of shorter grasses and fewer trees. Notable species include Isobertinia doka, I. tomentosa, Monotes kerstingii, and Uapaca togoensis among others (Adedibu et al 2022). The southernmost region of the North contains the derived savanna, which accords with climatic conditions and represents a limit of continuous forest.…”

Nigeria is one of the most floristic rich countries on the continent of Africa due to the variation in climate, which favors the growth of several species. Sadly, its biodiversity is one of the most threatened in the world, mainly due to deforestation and various unsustainable land use patterns, which are human activities. However, these anthropogenic activities are more prevalent in Nigeria's northern savanna zone (NSZ). In this study, we present the first regional conservation assessments and red listing of tree species in the northern savanna zone (NSZ) of Nigeria according to the International Union for Conservation of Nature (IUCN) criteria and categories. We recorded 31 tree species as the most utilized in the region. For the assessments, we provided the fundamental taxonomic information of each species, their local names, and their uses. This study provided the extent of occurrence, area of occupancy, population size and trend, description of habitats, and ecological requirements and discussion of the threats affecting each species and their habitats. We further inform conservation actions and research activities needed to ensure the future of the tree species and their sustainable uses. Overall, approximately 97% of the taxa were evaluated as threatened (41% as endangered, 31% as critically endangered, 24% as vulnerable, and 4% as least concerned). Therefore, we recommend the adoption of the risk status of the species to develop sound conservation strategies and measures for the management of flora in this inundated region.

“…The Nigerian economy is mainly agrarian, with over 70% of the people in agriculture (Ayinde et al, 2020). Rainfall patterns varied widely, from around 2500 mm per annum in the south to less than 600 mm per year in the extreme north (Adedibu et al, 2022). The average annual temperature range is from 28℃ in the south to 42℃ in the north.…”

Nigeria's food production heavily relies on smallholder rainfed agriculture. Unfortunately, this sector is highly vulnerable to the negative impacts of climate change, such as floods and droughts. It is crucial to examine the frequency, intensity, and magnitude of these events and develop effective mitigation and adaptation strategies to ensure the resilience of Nigeria's agricultural system. This study analyses rainfall variability in Nigeria's agroecological zones (AEZs) over the past sixty years. The research evaluates annual, quarterly, and seasonal rainfall patterns and uses the Standardised Precipitation-Evapotranspiration Index (SPEI) to examine drought and flood frequency and intensity. The study's findings reveal that the period from 1981 to 1990 experienced the weakest rainfall patterns across all AEZs, while the best occurred from 1961 to 1970. The humid forest zone consistently received the highest rainfall, although with a declining trend over the decades. Conversely, the Arid/Sahel and Semi-arid zones exhibited the lowest with a slight upward trend in precipitation, while others experienced a reduction. Spatial analysis of drought patterns also reveals that most of the AEZs face high drought risks, with over 65% of the country experiencing a considerable increase in drought in the last three decades. The rainfall pattern was less erratic in zones of lower latitudes than in the higher altitudes. Heavy rainfall events exceeding 10 mm and 20 mm revealed a decreasing trend from the Arid to the Humid Forest zone. Extreme weather events have significant economic consequences. Policymakers and stakeholders must take action to ensure climate resilient and sustainable agricultural production systems.
