Can Solar‐Powered Irrigation Systems Naturally Meet Crop Water Requirements? Proof of Concept From a Case Study in Sub‐Saharan Africa

Irrigation and Drainage, EarlyView.
ABSTRACT Irrigation scheduling is crucial for ensuring precise water delivery to crops. However, in many sub‐Saharan African irrigation schemes, water is applied without considering crop water needs, resulting in low crop water productivity and low yields. Solar‐powered irrigation systems can automatically meet these needs by utilizing solar radiation,

Transmission Water Losses at South African Irrigation Schemes: A Case Study of the Vaalharts Irrigation Scheme

Irrigation and Drainage, EarlyView.
ABSTRACT Irrigation water supply is under scrutiny because of dwindling water resources. Most irrigation water in South Africa (SA) is transmitted by canals. Transmission water loss (TWL) accounts for 12% of the irrigation water losses in SA. Therefore, there is a need to investigate and understand the major parameters influencing TWL at Vaalharts ...
