La micro-irrigation et les ressources en eau au Maroc : un coûteux malentendu

Alternatives Rurales, 2017
Depuis une dizaine d’années, le Maroc a engagé un plan ambitieux d’investissements dans le domaine de l’agriculture. Dans un contexte où le potentiel de mobilisation de ressources supplémentaires est marginal et où le déstockage annuel des nappes est de ...

Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches

Irrigation and Drainage, Volume 74, Issue 4, Page 1395-1409, October 2025.
ABSTRACT Clogging represents a critical challenge that undermines the efficiency and sustainability of drip irrigation systems by inducing uneven water distribution and increasing maintenance requirements. In this study, the phenomenon of clogging in drip emitters was investigated via computational fluid dynamics (CFD) in conjunction with the discrete ...

Potential of Photovoltaic and Diesel Off‐Grid Systems for Irrigation in Brazil Considering Carbon Credits

Irrigation and Drainage, Volume 74, Issue 4, Page 1553-1574, October 2025.
ABSTRACT Irrigation is a crucial practice for the security of rural businesses, ensuring agricultural production even in periods without rainfall. This work aimed to analyse the financial viability of an off‐grid photovoltaic (PV) system as an alternative to traditional energy sources for pumping irrigation in Brazilian agricultural areas.

Can molecular oscillation technology be used as an alternative to acid injection to prevent the clogging of emitters in drip irrigation systems?

Irrigation and Drainage, Volume 74, Issue 2, Page 586-599, April 2025.
Abstract In this study, molecular oscillation technology (Merus ring), developed to prevent calcification, biofilm formation and corrosion in piping in industrial water treatment systems, was compared as an alternative to acid injection to prevent the clogging of emitters by chemicals, and fresh and saline water were compared on the basis of system ...

Sunflower germplasms’ response to different water and salinity stress levels in greenhouse and field conditions under subsurface drip irrigation

Irrigation and Drainage, Volume 74, Issue 1, Page 161-181, February 2025.
Abstract Sunflower (Helianthus annuus L.) is moderately tolerant to salt and water stress, but its production can still be significantly and adversely affected by increases in these stressors as a result of the negative impacts of climate change on agricultural soil and crop productivity.

A simple method for evaluating the relative water uptake rate of drip‐irrigated crops

Irrigation and Drainage, Volume 73, Issue 4, Page 1231-1245, October 2024.
Abstract Drip irrigation is widely acknowledged for its water use efficiency, yet evaluating relative water uptake rates (RWURs, ratios between the water uptake rates and the irrigation rates) remains pivotal for effective system design and management.

Integrating Direct Experimental Fishing and Environmental DNA Metabarcoding to Assess Fish Biodiversity in the Cibareno River, Indonesia, to Support Fishway Design

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 9, September 2024.
ABSTRACT A fishway is an engineered structure designed to help fish navigate past artificial barriers in rivers such as dams, weirs and regulators. An effective fishway design requires an understanding of fish biodiversity and migration requirements of the local community.

Exposure to Persistent Organic Pollutants in Australian Waterbirds

Environmental Toxicology and Chemistry, Volume 43, Issue 4, Page 736-747, April 2024.
Abstract There is growing worldwide recognition of the threat posed by persistent organic pollutants (POPs) to wildlife populations. We aimed to measure exposure levels to POPs in a Southern Hemisphere aquatic waterbird species, the nomadic gray teal (Anas gracilis), which is found across Australia.
