Agriculture has a significant environmental impact, with food production contributing to around one-quarter of the world's greenhouse gas emissions. The environmental effects of the food system can be grouped into three categories: environmental contaminants/pollutants, depletion and replenishment of natural resources, and population and community disruption. Pesticides, for example, contaminate water, soil, and air, leading to biodiversity loss and pest resistance. In France, the wine regions of southern France have used CLC data to monitor vineyard landscapes and assess environmental threats such as Pierce's disease, a pest that damages grapevines. While this information helps protect wine production, it also highlights the challenges of balancing food production with environmental sustainability.

Water pollution
The quality of water is of utmost importance in food production, and it is dependent on the source and application of the water. Water pollution can occur at any stage of food production and can be caused by physical, chemical, or biological agents, which pose significant health hazards. Water used as an ingredient in food must be free from undesirable taste, odor, color, and impurities, including pathogenic organisms that could be harmful to consumers and affect product quality.
Water has a wide range of uses in food production, from being an ingredient to being used for cleaning, sanitation, and manufacturing. It is used for growing, unloading, fluming, washing, brining, ice manufacture, and in hygiene programs. The underestimation of the importance of water quality in food production can lead to problems such as mismanagement of water, equipment operation, and maintenance issues.
To address water pollution, France has implemented various measures, including costly water treatments to comply with regulatory standards. In 2007, treatments were applied to reduce nitrate rates and eliminate pesticide residues in drinking water. The EU Water Framework Directive, adopted in 2000, aims to achieve good water status for all water bodies and encourages the protection of water sources for drinking water. Additionally, France promotes the use of clean fuels, with LPG and NGV vehicles benefiting from a VAT deduction.

Greenhouse gas emissions
The food system, including production, processing, transport, packaging, and retail, plays a crucial role in tackling climate change. A shift towards plant-rich diets and alternative proteins can significantly reduce greenhouse gas emissions. Animal-based foods, particularly red meat, dairy, and shrimp, are associated with higher emissions. Methane emissions from cattle digestion and nitrous oxide from manure and fertilizers are potent greenhouse gases.
Industrial agriculture, including concentrated animal feeding operations (CAFOs) or factory farms, contributes to air pollution and soil and water degradation. Chemical fertilizers and pesticides used in conventional crop production contaminate soil and waterways, impacting biodiversity and human health. Pesticides have been detected above safe levels in European rivers and lakes, and agricultural soils are often polluted with pesticide residues.
To address these issues, improved agricultural practices are essential. This includes better manure and fertilizer management, rotational grazing, and restoring degraded lands. Reducing food waste is also critical, as food waste contributes significantly to global greenhouse gas emissions. Composting leftovers can help reduce methane and CO2 emissions from organic waste.
Overall, tackling greenhouse gas emissions in the food production system requires a systemic change involving all actors along the value chain, from producers to consumers.

Pesticide use
Pesticides are widely used in agriculture to control pests, weeds, and diseases. While pesticides ensure less weed and pest damage to crops and consistent yields, they have negative impacts on the environment and human health. Pesticides contaminate water, soil, and air, contributing to water scarcity and air pollution. They also harm terrestrial and aquatic biodiversity and drive biodiversity loss.
In Europe, the use of pesticides above safe thresholds has been detected in rivers and lakes, and pesticide residues have been found in agricultural soils. France is one of the countries that reported significantly higher sales of pesticides in 2018 than in 2011. Despite policy measures to reduce pesticide use in France, application rates remain high, and reduction targets are not met. Factors such as low taxes on chemicals and high prices for cereals create incentives to use more pesticides to protect harvests.
Farmers who sell their crops directly to consumers tend to use fewer synthetic pesticides, but those who sell through long food supply chains use more. Research suggests that reducing pesticide use can lower costs, improve health, and prevent pest resistance without affecting crop yields. However, the magnitude of the negative effects of pesticides is still unclear due to scattered and heterogeneous data.
To address the negative externalities of pesticides, effective public policies are needed, but this is challenging due to the complex characteristics of externalities, including their multidimensionality and the diffuse nature of pesticide pollution. Assessing the social costs and benefits of pesticide use is crucial for developing efficient policies, but it is difficult to implement in practice.
Overall, the widespread use of pesticides in food production in France has negative consequences on the environment and human health, and efforts to reduce pesticide reliance are ongoing.

Food waste
In France, food waste is a pressing issue, with an estimated 57 million tons generated annually, at a cost of EUR 130 billion. To address this, France implemented a groundbreaking food waste law in 2016, banning large grocery stores from throwing away unsold food that could be donated. This law has improved food waste management and increased food donations, with stores also benefiting from tax breaks on donated inventory.
Despite this progress, challenges remain. Agriculture accounts for 32% of food waste in France, followed by food processing at 21%, consumers at 19%, and restaurants at 14%. Pesticides, widely used in agriculture, contaminate water, soil, and air, leading to biodiversity loss and pest resistance. Additionally, the production and disposal of plastics contribute to pollution and climate change.
To further reduce food waste and its environmental impact, France promotes a transition to a circular economy. This framework encourages the reuse and recycling of resources, reducing waste and conserving natural resources. By implementing system-wide changes and promoting sustainable practices, France aims to tackle food waste and mitigate its contribution to pollution and climate change.
Overall, food waste is a critical issue with far-reaching consequences. France's efforts to address this problem through legislation and a shift towards a circular economy demonstrate a commitment to reducing waste and protecting the environment. By targeting food waste at its sources and promoting sustainable alternatives, France is taking significant steps towards a more sustainable future.

Land use
In France, agriculture covers approximately 28 million hectares (about half of its territory), with 74 million acres (30 million hectares) of usable agricultural area. More than half of this arable land is used for cereals, with the bulk of production in the Paris Basin and southwestern France. Another one-seventh of the agricultural area is used for forage crops, although this has been shrinking since the 1980s due to reduced dairy herds. Oilseed cultivation has increased substantially and now covers about one-tenth of agricultural land.
France's varied relief, soils, and climatic zones provide ample opportunities for agriculture and forestry. The country has a significant agricultural sector, with about 456,000 farms and 708,170 farmers. While agriculture employs a relatively small percentage of the labour force (around 3%), it is the EU's leading agricultural nation, with the highest value of agricultural production among EU countries, at EUR 72.9 billion.
To promote sustainability and reduce environmental impacts, France is encouraging more ecologically sound and less intensive agricultural practices. The country aims to halve the use of chemical pesticides by 2025 and promote alternatives like biopesticides and bio stimulants. France is also embracing digitalization, robotics, and biotechnology in agriculture, with a focus on climate management and disease-resistant seeds.
Additionally, France is committed to preserving permanent grasslands and promoting plant protein production, agroecology, and organic farming. These initiatives contribute to the country's CAP Strategic Plan, which aligns with the European Green Deal's objectives and carbon neutrality goals.

Frequently asked questions
Water pollution is caused by agriculture in several ways. Firstly, large amounts of freshwater are used in agriculture, which can cause environmental pressures in regions with water stress. Agriculture also pollutes rivers, lakes, and oceans by releasing nutrients and chemicals. For example, pesticides used in agriculture contaminate water bodies, as evidenced by the detection of pesticides above human health risk thresholds in 22% of monitoring sites in European rivers and lakes in 2020.
Agriculture is a significant contributor to the emission of harmful air pollutants, such as ammonia, and greenhouse gases. Greenhouse gases, including methane, carbon dioxide, and nitrous oxide, are emitted during meat production through cattle digestion, manure decomposition, and the use of chemical fertilizers. Plant-based foods generally produce fewer emissions than meat and dairy.
Land pollution from food production occurs through soil degradation, the use of pesticides and fertilizers, and biodiversity loss. Soil pollution is evident, with 83% of agricultural soils tested in a 2019 study containing pesticide residues. Pesticides also contribute to biodiversity loss by affecting pollinating insects and plant populations.
