With a rapidly expanding human population, urbanization, poverty, and threats from climate change, new innovations are needed to achieve global food security nutrition requirements in just sustainable manner. Agricultural biotechnology has the potential step changes crop productivity nutritional content meet these needs whilst minimizing agricultural environmental impacts, but critical questions remain on how technology is developed used, for whom. This special collection collates latest thinking natural social sciences surrounding help engage, enrich, stimulate debate, inform policy.

A data-driven framework for assessing climatic impact drivers in the context of food security

Natural hazards and earth system sciences, Journal Year: 2025, Volume and Issue: 25(4), P. 1387 - 1404

Published: April 10, 2025

Abstract. Understanding how physical climate-related hazards affect food production requires transforming climate data into relevant information for regional risk assessment. Data-driven methods can bridge this gap; however, more development must be done to create interpretable models, emphasizing regions lacking availability. The main objective of article was evaluate the impact risks on security. We adopted climatic driver (CID) approach proposed by Working Group I (WGI) in Sixth Assessment Report (AR6) Intergovernmental Panel Climate Change (IPCC). In study, we applied CID framework using a random forest model bootstrapping experiment identify most influential indices driving crop yield losses. also used SHapley Additive exPlanations (SHAP) with explanatory analysis, enabling us pinpoint critical thresholds these indices–thresholds that, when exceeded, significantly increase probability impact. Additionally, investigated effects two types (heat and cold wet dry) represented categories extreme yields, particular focus maize soybeans key agricultural municipalities Brazil. found that mean precipitation is highly CID. However, there window which crops are vulnerable deficit. many Brazil, example, face an increased losses falls below 100 mm per month December, January February – marking end growing season those areas. Nevertheless, including means remains recommended studying agriculture. Our findings contribute body knowledge informed decision-making, policy adaptive strategies response change its

Smallholder Farmers’ Perceptions of Climate Variability and Land-Use Changes in Semiarid Gwayi Catchment Agroecosystems

Earth, Journal Year: 2025, Volume and Issue: 6(2), P. 45 - 45

Published: May 20, 2025

Climate variability and land-use changes are critical challenges impacting agriculture globally, with Zimbabwe’s Gwayi catchment area experiencing noticeable effects. This study investigated how smallholder farmers in the region perceive these their influence on agricultural productivity livelihoods. The research addresses gap understanding local farmer experiences climate change modifications context of food security. A cross-sectional survey (n = 483) was conducted using self-administered questionnaires to capture demographic information, perceptions variability, changes, impacts agriculture. results indicate a trend increasing droughts, dry spells, heatwaves, alongside altered rainfall patterns rising temperatures, corroborating observed data. Environmental degradation, including deforestation, gully formation, land expansion, exacerbates changes. Consequently, reported substantial reductions crop yields, 84.05% significant-to-very negative impacts, declining livestock health (32.51% reporting very impacts), increased water scarcity (43.3% drying sources), more frequent disease outbreaks. These collectively contributed heightened insecurity, 74.12% households supply. underscores synergistic highlighting urgent need for climate-smart practices sustainable management enhance resilience ensure long-term security catchment.

Accumulation of Stinging Nettle Bioactive Compounds as a Response to Controlled Drought Stress

Agriculture, Journal Year: 2023, Volume and Issue: 13(7), P. 1358 - 1358

Published: July 6, 2023

As the impact of global warming intensifies drought effects, plants need to adapt and other climate change-induced stresses through various defense mechanisms. One them is increased synthesis bioactive compounds (BCs), which helps overcome adverse environmental conditions. This effect can be used in sustainable controlled cultivation as a tool for nutritional improvement crops, so this study focused on growing stinging nettle (Urtica dioica L.) human consumption environment. Since consumed green leafy vegetable due its value, aim was determine content BCs (ascorbic acid, phenolic compounds, pigments) antioxidant capacity leaves grown under different stress conditions an ebb flow hydroponic system. During experiment, were treated with nutrient solution adjusted 1 hour then exposed three intervals: 24, 48, 96 h. 48 h interval, accumulated highest amounts total non-flavonoid (400.21 237.33 mg GAE/100 g, respectively), during amount ascorbic acid (96.80 mg/100 g fw). The recorded 24 treatments (2435.07 2444.83 µmol/TE, respectively) according ABTS treatment (3773.49 µmol/TE) FRAP assay. obtained results show that durations caused by absence solutions have positive accumulation BCs.
