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 (

On‐Farm Demonstration and Economic Evaluation of an IoT Sensing System for Irrigation Management in South Carolina

Irrigation and Drainage, EarlyView.
ABSTRACT Irrigation can strongly influence agricultural productivity and sustainability. While sensor‐based irrigation has the potential to improve yield, reduce input costs and enhance resource‐use efficiency, its adoption in commercial agriculture remains limited.

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 ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Geen verband tussen kosten en rendement van pensioenfondsen [PDF]

, 2019
Omdat de vermogensbeheerkosten van pensioenfondsen aanzienlijk zijn, zou een kostenreductie de druk op premies en uitkeringen kunnen verlichten. Voorwaarde daarvoor is dat kostenverlaging niet leidt tot een lager rendement. Wat vertellen de data over het

Rethinking intensification: Biodiversity‐inclusive management sustains coconut yields

PLANTS, PEOPLE, PLANET, EarlyView.
Coconut palm expansion in West Africa will shape rural livelihoods and ecosystems. Our findings show that intensive practices reduce beneficial soil fungi and increase pathogens, threatening long‐term productivity. Lower‐intensity management that retains ground vegetation can sustain or boost yields while improving soil health.
