Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States

Irrigation and Drainage, EarlyView.
ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...

Inline Oxygenation in Drip‐Irrigated Citrus: How Much Agrochemical Reduction Is Needed to Achieve Net Environmental Benefits?

Irrigation and Drainage, EarlyView.
ABSTRACT The agronomic benefits of oxygen‐enriched irrigation, such as improved root development, enhanced nutrient uptake, and reduced fertiliser and pesticide requirements, are well documented. However, incorporating oxygenation devices into fertigation systems increases energy demand and material use, thereby incurring additional environmental ...

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 ...
