“…Table 2 describes the different moisture categories characterising flood or drought severity classes after Liu et al (2021). Trend analysis with Man-Kendall (MK) test MK test was conducted on the data to monitor and detect significant upward or downward trends on a decadal and seasonal basis concerning rainfall and temperature data (Espinosa and Portela, 2020;Shah and Kiran, 2021;Banda et al, 2021;Akudo and Otaru, 2023). The trend test's results with positive values indicate an increasing trend over time for the measured parameters, while negative values indicate a decreasing trend (Nyikadzino et al, 2020;Agbo et al, 2021;Agbo et al, 2023).…”

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.

“…The temperature in the research location is characteristic of the savannah climate of West Africa's Sokoto basin. One of Nigeria's warmest locations is the Sokoto basin, which is situated in the Sahel region of Africa (Akudo and Otaru, 2023;Ilesanmi, 2023). Therefore, Zamfara has a dry and wet type of climate.…”

The goal of the geothermal study over Ramfashi and Environs in Northwestern Nigeria was to use aeromagnetic data to determine the region's heat flow, geothermal gradient, and Curie point depth. For the purpose of analyzing the aeromagnetic data, on residual and regional magnetic intensity were gathered using regional residual separation. The residual data was upward continuued to obtain the upward data to perform spectral analysis. This allowed for calculation of depths to centroid and top boundary, which in turn allowed for calculation of region's heat flow, geothermal gradient, and Curie point. The analysis's conclusions revealed that, with an average value of 48.53 °Ckm-1, the distances to the heat flow, top boundary, centroid, and Curie point varied between 6.73 km and 7.39 km, 2.01 km and 2.16 km, and 113.55 mWm-2 and 128 mWm-2 respectively. Geothermal gradient also varied between 45.42 °Ckm-1 and 51.33 °Ckm-1. According to the heat flow data from this investigation, the area possesses anomalous geothermal energy and a sizable heat source.
