“…Nearly 10% of the moisture available in the atmosphere is from the T process [14]. The remaining 90% is mainly from the E process from different water bodies [15,16]. reported that the T is attained by the movement of water, at the vapor phase through the conductor system from the roots to the leaves of the plant, as a function of a water potential gradient from the soil (ψsoil) to the air (ψair) as shown in Figure 1.…”

“…Depending on the vegetation conditions, size of the vegetated area, and soil water supply, different conceptions are to be defined, such as potential, actual, oasis, and crop ET [16]. Such particular terms are described as follows.…”

“…Both the processes are influenced by temperature, humidity, sunlight, and wind as well as Earth vegetation. ETp values indicate the amount of water that has been lost, and thus needs to be replaced, through irrigation and/or rainfall [16,17].…”

“…Oasis ET is the amount of water consumed by a small irrigated vegetation which is encircled by a widespread dry-area, at which dynamism of water to vapor is come from high temperature in combination with drought [16,18]. Figure 2 shows the border area necessary for minimizing the lateral transport of energy from the dry to the wet area (irrigated).…”

“…Evapotranspiration is the process by which an amount of water is used by any growth stage of a crop from sowing to harvest, at whatever time there is no water constraint in the soil [13,16]. ETc is a function of leaf area (transpiring surface), because the bigger the leaf area (LAI), the higher ETc will be for the same atmospheric demand [17].…”

The chapter provides an inclusive information related to the adverse effect of climate change on sustainable crop production through understanding evaporation, transpiration as well as evapotranspiration. It is anticipated that water availability in arid and semi-arid regions across the world will decrease, due to lack of rainfall and increase the temperature which leads to increase in the dry areas. Since climate change will impact on soil water balance that leads to change in evaporation and plant transpiration. While, with the increasing temperature, lack of precipitation and soils water unavailability, crop production will likely to decrease through shortening the crop growth cycle. While soils with high water holding capacity and crop cultivars which are tolerant to adverse effect as well as the application of improved management strategies will be better to reduce the impact of drought. Similarly, if the irrigated areas will be expanded, the total crop production will be increased that ultimately lead to increase the food security of increasing population.

Several studies have been undertaken on surface energy balance (SEB) at various places in the world, but none have been undertaken for Mubi, Northeastern Nigeria. In the effort of consideration, this study aims to evaluate the seasonal variation of SEB in Mubi, with emphasis on the observational data from 2000 to 2020. Evaluation of seasonal variations was executed using time series analysis to find out the impact of precipitation, evapotranspiration, soil, and air temperature changes on SEB components. It was found that the SEB components variations of sensible heat (H) had a maximum value of 1035.13 Wm−2 in the dry season, in the month of December, while a minimum value of -104.13 Wm−2 during the rainy season, in the month of July; latent heat (LH), had a peak value of 5243.46 Wm-2 in the dry season in the month of April, while in the rainy season, the lower value was found to be 2460.6 Wm-2, in the month of August; soil heat (G) had minimum and maximum values of 886.43 Wm-2 in March and 275.25 Wm-2 in August respectively; and net radiative (Rn) varies roughly between the highest month in March with 2809.35 Wm−2 (rainy season months) and lowest month in August with 6879.69 Wm−2 (dry season months). It was also found that precipitation, evapotranspiration, soil, and air temperature follow the same trend with some SEB results, affirming their dependency on each other. Therefore, it is expected that this study will help to understand the amount of energy received or emitted in the Mubi region. Along with the main work, some recommendations were made by researchers on some applications of SEB to the community.
