Evaluating Water–Energy–Food Nexus Strategies to Address Resource Scarcity in the Crocodile River Catchment, South Africa

Irrigation and Drainage, EarlyView.
ABSTRACT The water–energy–food (WEF) nexus approach highlights the interdependence of water, energy and food resources, all of which play central roles in agriculture, especially irrigation. A WEF nexus lens was applied to Mpumalanga's Crocodile River catchment, a vital irrigation area that significantly contributes to South Africa's staple food ...

Evaluating Reference Evapotranspiration (ETo) Calculation Methods and Quantifying Climate‐Driven Change in Irrigation Demand Across Nepal's Terai

International Journal of Climatology, EarlyView.
Framework illustrating the comparison of different reference evapotranspiration (ETo) estimation methods and the integration of baseline ETo, crop water requirement (CWR), and irrigation water requirement (IWR) calculations with downscaled CMIP6 climate projections under SSP245 and SSP585 scenarios for the mid‐century and late‐century periods across ...

Measuring Crop Evapotranspiration Over Hilly Areas

, 2018
Agricultural production systems around the Mediterranean basin rely mostly on rainfed agriculture in hilly watersheds, although some irrigation is sustained downstream of water reservoirs. With climate change and increasing demand for water, most commonly cultivated species, particularly cereals, are exposed to high risks of water shortages during the ...

Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis

International Journal of Climatology, EarlyView.
Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...

Effect of irrigation regime on yield and water productivity of wheat (Triticum aestivum L.) in the lowland area of Ethiopia

Discover Sustainability
Inadequate agricultural water management and insufficient knowledge of proper irrigation scheduling are major constraints to wheat productivity under irrigation in Ethiopia. To address these challenges, this study aimed to evaluate the effects of varying

Long‐Term Analysis of Winter Wheat Yield and Climatic Influences in Ukraine

International Journal of Climatology, EarlyView.
Long‐term field data (1968–2024) show that winter wheat yields in central Ukraine increased despite warming, but yield stability declined. Rising temperatures, more frequent soil moisture droughts and shortened winter calm increasingly limit productivity.

Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

International Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Modelling Evapotranspiration of Container Crops for Irrigation Scheduling

, 2011
Irrigation is now recognized as an important component in the agriculture economy of Mediterranean regions. As practiced by many growers, it is often based on traditional application methods that fail to measure the supply of water needed to satisfy the variable requirements of different crops.
