A trajectory of social innovations for the direct purchase of organic food by food services: a case study in Florianópolis, Brazil

open access: yesFrontiers in Sustainable Food Systems, 2023
IntroductionAlthough interest in the so-called short food supply chains (SFSC) has grown in recent decade, studies and social innovations that emerged from this phenomenon have made little progress in involving food actors outside the home.

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

open access: yesAdvanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Assessing the hidden impacts of hypothetical eruption events at Mount Etna

open access: yesEnvironmental and Sustainability Indicators, 2020
We estimate how the value and the spatial distribution of carbon storage, water yield and wild pollination services are expected to change with potential expansion of lava flow inundation at Mount Etna volcano (Sicily, Italy).
