Farmers' Soil–Water Management Practices and Perspectives on Soil Salinization in Mirab Abaya District, Gamo Zone, Southern Ethiopia

Irrigation and Drainage, EarlyView.
ABSTRACT Soil salinization is a critical threat, impacting 20% of the world's irrigated lands and jeopardizing food security. In Ethiopia's Mirab Abaya district of the Gamo Zone, unsustainable irrigation methods exacerbate this issue. This paper examines local farmers' soil–water management systems and their awareness of salinization, aiming to educate

Maize Yield, Water Productivity and Economic Analysis Under Different Irrigation and Nitrogen Management Strategies Using Field Data and CERES‐Maize Model

Irrigation and Drainage, EarlyView.
ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

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 ...
