The impact of excess water on our crops

Excess Water: A Threat to French Agriculture 🌧️🌾

In recent years, French agriculture has faced growing challenges exacerbated by the effects of climate change. Among these, excess water stands out as a major problem, severely disrupting production and highlighting the need to transform agricultural practices.

Excess Water: Consequences at Every Stage of the Agricultural Cycle

Excess water, amplified by the resurgence of extreme weather phenomena, profoundly disrupts agricultural seasons:

• At the time of sowing: Waterlogged soils become impassable, delaying agricultural work or forcing farmers to change their schedules.
• During the growing season: Saturated soils prevent root aeration, causing asphyxiation and promoting the appearance of fungal diseases.
• During harvest: Prolonged humidity leads to problems with grain germination on the stalk and complicates drying, making harvesting difficult, costly, and of lower quality.
• Lack of sunshine: Long periods of clouds reduce photosynthesis and affect grain filling, further aggravating yield losses.

Recent example: French wheat in distress.

Over the past ten years, three major crises illustrate the impact of excess water on wheat cultivation in France:

1. 2016: Abundant rainfall between April and June floods the fields. Harvests are catastrophic, with a 20% drop in production.
2. 2020: Rainfall during sowing leads to significant delays, again causing a drop in yields of around 20%.
3. 2024: The worst episode in 41 years, marked by excess water from sowing to harvest. Fields are inaccessible, diseases proliferate, and yields collapse, a direct consequence of an increasingly unpredictable climate.

These increasing events, due to phenomena such as the intensification of atmospheric rivers, highlight the urgency of acting to adapt our agriculture.

Solutions for resilient agriculture.

1. Improved Water Management:

Water management becomes crucial in the face of increasingly saturated soils:

• Optimized drainage systems: Efficient infrastructure to quickly remove excess water.
• Connected technologies: Humidity sensors to anticipate critical periods and adjust practices in real-time.

2. Crop Diversification:

Given wheat's vulnerability, it is essential to integrate more resilient crops:

• Sorghum: This cereal tolerates both excess and lack of water, while requiring fewer inputs.
• Millet: Resistant to climatic variations and adapted to poor soils, it represents a promising alternative.

3. Ecosystem and Soil Restoration:

Agroecological practices, such as conservation agriculture or regenerative hydrology, allow for:

• Restoring the water cycle and improving soil water retention.
• Strengthening biodiversity, essential for sustainable agricultural ecosystems.

4. Research and Innovation:

The development of wheat varieties adapted to extreme climatic conditions, combined with innovations in agricultural machinery, can limit losses related to excess water.

Conclusion: Reinventing French agriculture for a sustainable future

Episodes of excess water, now recurrent, reflect a profound climatic upheaval that forces agriculture to reinvent itself. By severely affecting wheat cultivation, these phenomena jeopardize a pillar of French food security.

Solutions exist, but they require collective mobilization and rapid adaptation: investing in modern infrastructure, adopting resilient crops like sorghum or millet, and reintroducing sustainable agricultural practices to regenerate soils.

This transformation must not only respond to current crises but anticipate future challenges. By diversifying production and adapting our agricultural systems, we can not only protect French agriculture but also create a resilient model that respects ecosystems and is better prepared for climatic hazards.

The future of French agriculture is in our hands. By acting today, we can build a system capable of sustainably feeding future generations. 🌍
