Artificial Neural Networks for Defining the Operational Parameters of Sand Filters for Irrigation

Irrigation and Drainage, EarlyView.
ABSTRACT The difficulty in defining the working configuration during the operation of sand filters arises from the complexity of the relationships among the variables in the filtration and backwashing processes. The objective was to use artificial neural networks to model the pressure loss and removal efficiency of filtration in a commercial sand ...

Agroforestry Innovation through Planned Farmer Behavior: Trimming in Pine–Coffee Systems

Land, 2020
Knowledge transfer depends on the motivations of the target users. A case study of the intention of Indonesian coffee farmers to use a tree canopy trimming technique in pine–based agroforestry highlights path-dependency and complexity of social ...

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

Irrigation and Drainage, EarlyView.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Farmer‐Led Strategies for Water Conservation in the Urmia Lake Basin, Iran

Irrigation and Drainage, EarlyView.
ABSTRACT This study examines the urgent issues of water scarcity and limited farmer livelihoods in the Urmia Lake basin. To address these challenges, we apply the Governance, Autonomy, Integration, and Needs orientation (GAIN) methodology. Our participatory approach revealed that farmers prioritised actionable measures for water management, yield ...

Spatial modeling for detection of water retention capacity in technosols developed on carboniferous spoil heap after hard coal mining

Ecological Informatics
Post-industrial areas, such as heaps, are an Anthropocene pressure on the environment but show natural potential for new ecosystem services, i.e., water retention, biodiversity, and C-sequestration.

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, EarlyView.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Biomonitoring of Environmental Pollution Using Forest Tree Foliage Chemistry at Extremely Contaminated, Post-Industrial Sites

Atmosphere
Biomonitoring based on foliage chemistry was used to study the effects of environmental sulfur (S) pollution on forest stands. The foliage samples were collected in two forest ecosystems exposed to industrial emissions: a zinc (Zn) and lead (Pb) smelter ...

A First Quantitative Assessment of Soil Health at European Scale Considering Soil Genesis

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Soil health degradation is a major threat to European food security, biodiversity, and climate stability. While scientists have debated how to define soil health during recent decades, a quantifiable framework for monitoring, management, and policy remains lacking.
