Modeling climate adaptive habitat connectivity for conservation planning in Colombia

Ecography, EarlyView.
To remain effective under global change, conservation decisions must anticipate shifting climates, species responses to climate change and the dispersal pathways needed to track suitable climate. Yet most assessments of ecological connectivity do not consider how the landscape will change, or, if they do, they only consider a single future time point ...

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

Food Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Understanding the hydrological response of a headwater-dominated catchment by analysis of distributed surface–subsurface interactions

Scientific Reports, 2023
We computationally explore the relationship between surface–subsurface exchange and hydrological response in a headwater-dominated high elevation, mountainous catchment in East River Watershed, Colorado, USA.

Green water, wetlands, and atmospheric moisture recycling ‐ An emerging new paradigm for grassland science

Grassland Research, EarlyView.
The importance of green water in water resource management. Conceptual classification of terrestrial water components highlighting the central role of green water in land‐atmosphere interactions. This schematic distinguishes green water (soil moisture available for plant uptake and evapotranspiration) from blue water (surface water, groundwater, and ...

Influence of hydrological connectivity on winter limnology in 1 floodplain lakes 2 of the Saskatchewan River Delta, SK [PDF]

, 2015
Globally, hydrological connectivity between rivers and their floodplains has been reduced by river flow management and land transformation. The Saskatchewan River Delta is North America’s largest inland delta and a hub for fish and fur production.

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

Irrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Solute Evidence for Hydrological Connectivity of Geographically Isolated Wetlands

, 2018
Hydrological connectivity describes the water‐mediated transfer of mass, energy, and organisms between landscape elements and is the foundation for understanding how individual elements such as wetlands and streams integrate to support ecosystem services

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.
