Seasonal evapotranspiration signatures under a changing landscape and ecosystem management in Nigeria: Implications for agriculture and food security

Abstract: An understanding of the evapotranspiration processes and knowledge about the spatial and temporal rates of evapotranspiration is paramount for designing appropriate responses to climate change. But the knowledge about the processes is limited in many African countries. In this paper, we analyzed seasonal and regional trends of evapotranspiration for 36 state capitals of Nigeria and the federal capital, Abuja using data obtained from the International Water Management Institute (IWMI) for the period .

“…Similar patterns of discharge increase in the Niger basin due to rainfall increase was reported by Roudier et al [2]. This will aggravate the current problematic flooding in the region [26,59] which was already attributed to increasing rainfall trends and reduced infiltration due to replacement of natural (permeable) surfaces by man-made (impermeable) surfaces [8].…”

“…Rapid forest disappearance or deterioration, especially due to population pressures and non-sustainable resource utilization [8], poses great challenge to land surface schemes of global climate model (GCM) and regional climate model (RCM). Consequently GCM projections in West Africa are accrued with different biases relative to regional observations and no coherent rainfall trend emerges from GCM products [9].…”

“…The State is located in the rainforest agro-ecological region of Nigeria and shares common boundaries with Abia State on the east and northeast, Rivers State on the south, and Anambra State on the west and northwest (Imo State Agricultural Development Project (Imo-ADP, 2013). The State lies between Latitudes 5°45 1 and 6°35 1 North of the equator and Longitudes 6°35 1 and 7°28 1 East of the Greenwich Meridian (Chineke et al, 2011). It occupies the area between the lower River Niger and the upper and middle Imo River (Imo-ADP, 2013 (NBS), 2007) and population density of about 725km 2 (Imo-ADP, 2015).…”

“…The model has factors like wind speed, solar radiation, etc. The current extremes experienced in rainfall regimes alongside population growth in Nigeria inform the need for improvement in water management to boost food production (Chineke et al, 2011). Water use efficiency requires optimizing and maximizing water use through determining the actual water required by the crops (Rauf and Shittu, 2015).…”
