Import dependence and per capita production are main determinants of economies' food supply robustness under production shocks

Han-Yu Zhu, Maria Cristina Rulli, Wei‐Xing Zhou

Food supply shocks in major producing economies can propagate through trade networks and generate uneven impacts across the global food system. This study examines the robustness of economies' food supply under production shocks to major producers in the global staple food system. …

The land and water costs of the “green energy” transition

Paolo D’Odorico, Maria Cristina Rulli

The transition to renewable energy sources is expected to reduce anthropogenic greenhouse gas emissions and the associated impacts on global climate but it entails an increased human pressure on land and water resources. Here we evaluate the associated shift in environmental costs …

Hydrological modeling of traditional irrigation systems to cope with extreme drought conditions

Davide Danilo Chiarelli, Nikolas Galli, Francesca Padoan, Tommaso Casu et autres

Increasing drought frequency and severity are challenging the sustainability of agricultural water management, even in traditionally water-rich regions such as Northern Italy. Conventional irrigation systems, largely optimized for summer water demand, are increasingly unable to cope with prolonged water scarcity and declining …

Integrating biophysical models and remote sensing to evaluate irrigation practices in four global hubs

Nikolas Galli, Francesco Capone, Jacopo Dari, Davide Danilo Chiarelli et autres

Sustainable agricultural intensification through irrigation is necessary to address the challenges that climatic and demographic change pose to the global food system. This requires creating accurate regional-to-global knowledge bases of irrigation estimates, in a context where the availability of ground data is …

Quantifying Food Security Impacts of Hydrological Disasters Through Post-Event Assessments

Nikolas Galli, Camilla Govoni, Maria Cristina Rulli

Climate change is altering the frequency and intensity of hydrological extremes, amplifying their consequences for agriculture and food security. In regions already burdened by socioeconomic vulnerabilities, agricultural losses from floods and similar events can disrupt food systems far beyond crop produce availability …

Quantifying Crop Responses to Brackish Water Use Across the Mediterranean with Minimal Input Modelling

Harsh Nanesha, Maria Cristina Rulli, Davide Danilo Chiarelli

Water scarcity is tightening its grip on global agriculture as climate change advances, with the Mediterranean facing particular strain. About thirty percent of its 11.32 million hectares of irrigated land overlies saline aquifers, forcing farmers to depend on water of declining quality. …
