Impact of Sahelian Climate Variables on Solar Photovoltaic Output

Energy Science &Engineering, EarlyView.
ABSTRACT Solar photovoltaic (PV) energy is a critical pathway for advancing the energy transition in the Sahel. However, PV module performance in this region is strongly constrained by extreme climatic conditions. This study investigates the effects of (1) wind speed, (2) relative humidity, (3) temperature, (4) dust deposition, and (5) solar irradiance

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

Land Restoration as a Catalyst for Regional Economic Revitalization: Evidence From Urban–Rural Transition Zones

Land Degradation &Development, EarlyView.
ABSTRACT Large‐scale land restoration is widely expected to improve environmental quality, yet causal evidence on its local economic returns remains limited. This gap is especially important in urban–rural transition zones, where development pressure and ecological damage overlap.
