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

From rhetoric to measurement: The economics of wetland conservation

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract Wetland conservation continues to be a pressing issue as wetlands continue to be lost due to urban, industrial, and agricultural expansion. This paper synthesizes the current knowledge about wetland conservation economics in Canada, with a focus on prairie landscapes. We review the methods economists use to empirically measure the costs (i.e.,

Exploring the Impact of Climate Variability on the Resilience of Senegalese Farmers Through Nutrition, Economic, and Risk Factors

Food and Energy Security, Volume 15, Issue 1, January/February 2026.
ABSTRACT This study advances a novel, multidimensional approach to quantifying agricultural resilience to climate shocks by integrating economic, calories, and risk‐based indicators. To accomplish this, resilience is defined in terms of the failure–recovery dynamics of net cash farm income (NCFI) and daily calorie intake.
