Estimating Daily Rice Crop Evapotranspiration in Limited Climatic Data and Utilizing the Soft Computing Algorithms MLP, RBF, GRNN, and GMDH

Complexity, Volume 2022, Issue 1, 2022., 2022
Evapotranspiration represents the water requirement of plants during their growing season, and its accurate measurement at the farm is essential for agricultural water planners and managers. Field measurements of evapotranspiration have always been associated with many difficulties that have led researchers to seek a way to remotely measure this ...

Spatial‐Temporal Interpolation of Reference Evapotranspiration for Pakistan

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The unequal water distribution in the universe has resulted in more than 2 billion people living in water‐stressed areas. Globally, withdrawals of water resources are still below the critical level. Pakistan is also affected by this serious problem.

Effect of high population density of eastern black rhinoceros, a mega‐browser, on the quality of its diet

African Journal of Ecology, Volume 59, Issue 4, Page 826-841, December 2021., 2021
Abstract High density of herbivore populations can lead to intense foraging competition and depletion of food consequently lowering diet quality and population performance. We tested for the effects of the density of eastern black rhinoceros (Diceros bicornis michaeli) in nine in situ populations of 0.01–0.7 individuals per km2 density range on the ...

Water availability trends across water management zones in Uganda

Atmospheric Science Letters, Volume 22, Issue 10, October 2021., 2021
Study area with locations of datasets. Abstract This study assessed trends in gridded (0.25° × 0.25°) Climate Forecast System Reanalysis (CFSR) precipitation, potential evapotranspiration (PET), and precipitation minus PET (PMP) across the four water management zones (WMZs) in Uganda including Kyoga, Victoria, Albert, and Upper Nile.

Relationships of reproductive performance indicators in black rhinoceros (Diceros bicornis michaeli) with plant available moisture, plant available nutrients and woody cover

African Journal of Ecology, Volume 59, Issue 1, Page 2-16, March 2021., 2021
Abstract Plant available moisture and plant available nutrients in soils influence forage quality and availability and subsequently affect reproductive performance in herbivores. However, the relationship of soil moisture, soil nutrients and woody forage with reproductive performance indicators is not well understood in mega‐browsers yet these three ...

Estimating Reference Evapotranspiration by Hargreaves and Blaney-Criddle Methods in Humid Subtropical Conditions

Current Research in Agricultural Sciences, 2020
Various methods are available to predict reference evapotranspiration (ETo) but the Penman-Monteith (PM) ETo method has been considered to be the most accurate ETo method to determine ETo. The PM ETo method can be solved by various weather parameters like atmospheric temperature, wind velocity, moisture content and net solar radiations.
