In 2025, global climate extremes—from intense heatwaves to erratic floods—have severely disrupted agricultural systems, worsening the global food crisis. This article examines the crisis’s severity amid 2025’s harsh climate and how biostimulants offer a viable mitigation strategy.
The 2025 Global Climate Scenario
Extreme Temperatures
Per the World Meteorological Organization, 2025 continued 2024’s record heat, with H1 2025 temperatures 1.2°C above pre-industrial levels. Europe saw July heatwaves: Spain hit 45°C for weeks, causing wheat yield drops via plant heat stress (reduced photosynthesis, wilting). The Arctic warmed 10-15°C above average, thawing permafrost and altering soil conditions harmful to adapted crops.
Unprecedented Precipitation
2025 brought stark contrasts: sub-Saharan Africa (Kenya, Somalia) faced droughts that dried maize crops, while South Asia (India, Bangladesh) saw August floods. Floods submerged paddy fields, destroying rice and agricultural infrastructure.
Agricultural Disruption
Climate extremes disrupted all farming stages: unpredictable planting times, stunted growth from heat/drought/floods, and damaged harvests (e.g., lodged wheat, rotting fruit).
The Severity of the 2025 Global Food Crisis
Rising Hunger and Malnutrition
The Global Report on Food Crises 2025 (FAO, WFP, EU) noted 295 million people in 53 countries faced severe food insecurity in 2024—13.7 million more than 2023, with 1.9 million in “catastrophic” hunger (a record). Gaza (1.1 million in crisis, double 2023) and famine-hit Sudan saw climate worsen shortages. Over 38 million under-five children in 26 countries (Mali, Yemen) suffered acute malnutrition due to climate-driven crop failures.
Food Price Volatility
Extreme weather spiked prices. The table below highlights key increases:
| Region/Country | Food Item | % Price Increase (2024-2025) | Climate-related Cause |
| South Korea | Cabbage | 70% | 2024 East Asian heatwave |
| Japan | Rice | 48% | 2024 East Asian heatwave |
| China (Jun-Aug 2024) | Vegetables | 30% | 2024 East Asian heatwave |
| United States | Vegetables | 80% | 2022 California/Arizona drought |
| European Union (Jan 2024) | Olive Oil | 50% | 2022/2023 Southern European drought |
High prices pushed low-income households in developing countries into poverty, as food consumes most of their income.
Reduced Productivity
Global yields fell: African maize dropped 50% in drought zones; South Asian floods shrank cultivable land. Livestock suffered too—heat reduced grazing, drought cut water/forage, forcing herd reductions and lowering meat/milk supplies.
The Link Between Biostimulants and Crisis Relief
What Are Biostimulants?
Biostimulants (substances/microorganisms) boost plant nutrient uptake, abiotic stress tolerance (drought, heat), and quality—distinct from fertilizers, which only supply nutrients.
How Biostimulants Work
- Nutrient Efficiency: They chelate soil nutrients for easier absorption and improve internal nutrient use.
- Stress Tolerance:
- Drought: Induce osmolytes (e.g., proline) to retain water (e.g., seaweed-based stimulants for tomatoes).Heat/Cold: Regulate antioxidants to reduce reactive oxygen species (ROS) damage (e.g., plant-derived stimulants for wheat).
- Salinity: Control ion uptake (reduce sodium, increase potassium) and stabilize cell membranes.
- Quality Improvement: Boost beneficial compounds (e.g., grape polyphenols) and extend shelf-life.
Case Studies
DORA,China: Dora Kelpreal drought and sunscald resistance trials on chili peppers helped crops produce larger-diameter fruits (increasing the proportion of large fruits by 16.4%), optimized fruit size and weight, and improved survival rates and agricultural yields.
Mitigating Climate Risks
Biostimulants reduce climate-driven yield losses and promote sustainability by cutting reliance on synthetic inputs, preserving soil health for long-term food security.
Conclusion
2025’s climate extremes worsened hunger, price volatility, and low productivity. Biostimulants offer a solution via stress tolerance and nutrient efficiency. Collaboration between governments, NGOs, and farmers to scale biostimulant use is key to climate-resilient food security.
