“…The water crisis in the basin will significantly impact the livelihood of people as rainfed agriculture remains the main economic activity challenged by a long period of dry season. Abdul-Ganiyu et al (2011) however mention that the flow of Nasia river may not be attributed to climatic factors alone but also influenced by the physical characteristics (such as topography, soil, and vegetation) as well as human activities in the catchment. Adeyeri et al (2020) however reported that the contribution of human activity to annual discharge variation can be remarkably larger than the contribution of rainfall variability in several regions of the world.…”

“…The hottest month in the year is March or April, just before the beginning of the rainy season, while the coolest month is July or August. The average maximum and minimum temperatures of 34°C and 23°C, respectively, are recorded (Abdul-Ganiyu et al, 2011). The floodplain soils vary in texture, from very fine sands to heavy clays and are developed over levees, old river beds, sloughs and low river terraces.…”

“…Most of the Nasia basin is very gently undulating. It has broad, poorly-drained valleys and extensive floodplains adjacent to the Volta and Nasia rivers, where altitudes vary between 108 and 138 m above mean sea level (Abdul-Ganiyu et al, 2011). It has a relatively short rainy period, stretching from May -October, with estimated reference evapotranspiration (ETo) above 1600 mm/annum (Kranjac-Berisavljevic, 1999).…”

“…Many householders' sheep and goats, as well as chickens and guinea fowls, but few others keep cattle. The animals are kept for security reasons or as a capital investment (Abdul-Ganiyu et al, 2011).…”

“…It also reported a general reduction in annual river flows in Ghana by 15-20 % for the year 2020 and 30-40 % for the year 2050, due to an increased irrigation water demand of 40-150 % for 2020 and 150-1200 % for 2050 and a reduction in hydropower generation of 60 % for 2020 (Kankam-Yeboah et al, 2011). According to Abdul-Ganiyu et al (2011), the main surface water resources in Northern Ghana are concentrated in the White Volta and the Nasia River systems, which flows only three or four months during the year, causing seasonal deficits across the region. This poses serious problems for traditional rain-fed agriculture, especially as food demand grows, thus slowing down rural development.…”

The Nasia catchment is the reservoir for significant surface water resources in Northern Ghana and home to numerous subsistence farmers engaged in rainfed and dry season irrigation farming. Yet there is little understanding of the hydro-climatic and land use /cover conditions of this basin. We analyzed 50 years of minimum (Tmin) and maximum temperature (Tmax), wind speed (WS), sunshine duration(S), Rainfall(R), relative humidity (RH), discharge (D) and potential evapotranspiration (PET) data, 15 years of remotely sensed normalized difference vegetation index (NDVI) data and 30 years of land use/cover image data. Results show that Tmin, Tmax, WS, and PET have increased significantly (P < 0.05). RH and S significantly declined. R, D and NDVI have insignificantly decreased (P > 0.05). A significant abrupt change in almost all hydroclimatic variables started in the 1980s, a period that coincides with the occurrence of drought events in the region except WS in 2001, R in 1968 and D in 1975. Also, D showed a positive significant correlation with RH, R and PET, but insignificant positive relationship with S. D also showed negative insignificant correlation with Tmin, Tmax and WS. Areas covered with shrubland and settlement/bare lands have increased to the disadvantage of cropland, forest, grassland and water bodies. We conclude that climate change impact is quite noticeable in the basin; indicating water scarcity and possibilities of droughts. The analysis performed herein is a vital foundation for further studies to simulate and predict the effect of climate change on the water resources, agriculture and livelihood in the Nasia basin.

The Nasia catchment is the reservoir with significant surface water resources in Northern Ghana and home to numerous subsistence farmers engaged in rainfed and dry season irrigation farming. Yet, there is little understanding of the hydro-climatic and land use/cover conditions of this basin. This study investigated trends, relationships and changes in hydro-climatic variables and land use/cover in addition to implications of the observable changes in the Nasia catchment over a period of 50 years. Parameters used for the study were minimum (Tmin) and maximum temperature (Tmax), wind speed (WS), sunshine duration (S), rainfall (R), relative humidity (RH), discharge (D) and potential evapotranspiration (PET) data, 15 years of remotely sensed normalized difference vegetation index (NDVI) data and 30 years of land use/cover image data. Results show that Tmin, Tmax, WS and PET have increased significantly (p < 0.05) over time. RH and S significantly declined. R, D and NDVI have not decreased significantly (p > 0.05). A significant abrupt change in almost all hydro-climatic variables started in the 1980s, a period that coincides with the occurrence of drought events in the region, except WS in 2001, R in 1968 and D in 1975, respectively. Also, D showed a positive significant correlation with RH, R and PET, but an insignificant positive relationship with S. D also showed a negative insignificant correlation with Tmin, Tmax and WS. Areas covered with shrubland and settlement/bare lands have increased to the disadvantage of cropland, forest, grassland and water bodies. It was concluded that climate change impact is quite noticeable in the basin, indicating water scarcity and possibilities of droughts. The analysis performed herein is a vital foundation for further studies to simulate and predict the effect of climate change on the water resources, agriculture and livelihoods in the Nasia catchment.
