Agricultural policy is the collection of laws, regulations, subsidies, taxes, programmes, market interventions, environmental measures and public investments through which governments influence agriculture, farming and food production. It can cover farm support, commodity markets, land use, rural development, agricultural research, food security, environmental stewardship, animal health, plant health, water use, trade and agricultural infrastructure. Agricultural policy is broader than farm subsidies because governments can regulate production, establish food safety requirements, support research, manage risks, influence trade and provide environmental incentives.
The OECD monitors agricultural policies across a large group of countries using indicators designed to compare the nature and extent of agricultural support. Its classification includes measures such as market price support, payments based on output and payments linked to input use. Agricultural policy therefore concerns the relationship between farmers, consumers, markets, government and natural resources rather than simply the amount of money paid to farmers.
Farm support is a major component of agricultural policy because farming is exposed to weather, disease, price volatility, input costs and other risks that can create large fluctuations in income. Governments may provide direct payments, insurance support, disaster assistance, credit programmes or other mechanisms to manage these risks. Market price support can influence domestic prices by affecting the relationship between domestic and international prices, while output based payments link support to production.
Input based measures can reduce the cost of specific agricultural inputs or support capital investment in buildings, equipment, irrigation or soil improvements. The OECD's Producer Support Estimate framework distinguishes these different forms because they affect farmers and markets through different channels. Understanding agricultural support therefore requires identifying not only how much assistance exists but how it is delivered, who receives it and what economic incentives the policy creates.
Agricultural policy also concerns food security, which broadly relates to the availability, accessibility and reliability of food supplies. Governments may pursue policies designed to maintain domestic productive capacity, diversify supply chains, improve storage, support agricultural infrastructure or reduce vulnerability to major disruptions. Food security does not necessarily require complete domestic self sufficiency because countries can rely on international trade, but dependence on concentrated suppliers can create vulnerabilities. Agricultural policy therefore interacts with trade, energy, transport and foreign policy.
Fertiliser, fuel, machinery, animal feed and other agricultural inputs can depend on international markets, while food itself can cross borders extensively. Governments may respond to supply shocks through trade measures, emergency support or strategic reserves, although such measures can affect domestic and international prices. Agricultural policy must therefore consider both the interests of producers and the interests of consumers and the wider food system.
Agricultural policy has a major environmental dimension because farming depends on land, water, biodiversity and ecological systems while also affecting them. Agricultural activities can influence soil quality, water use, nutrient runoff, biodiversity, greenhouse gas emissions and habitat. Governments can therefore use agri environmental schemes, conservation requirements, nutrient regulations, land management rules, water policies and incentives for sustainable practices. Environmental agricultural policy can reward farmers for providing ecosystem services or complying with environmental standards.
However, environmental outcomes vary according to farming systems, geography and land use. A policy designed for one region may be inappropriate elsewhere because rainfall, soils, crops, livestock systems and ecological conditions differ. Agricultural policy consequently increasingly involves balancing food production with resource conservation and environmental objectives rather than treating agricultural output as its only measure of success.
Rural development is another component because agriculture is closely connected to the economic and social structure of rural areas. Rural policy can support infrastructure, diversification, broadband, local services, skills, agricultural processing and alternative sources of income. Agriculture may provide employment directly while also supporting food processing, machinery services, logistics and other industries. A decline in agricultural employment can therefore affect rural communities beyond individual farms.
Agricultural policy may consequently be combined with regional development measures intended to maintain viable rural economies. The appropriate balance depends on the importance of agriculture within the national economy and the characteristics of rural regions. In some countries, agriculture is dominated by smallholder farms, while in others production is highly mechanised and concentrated among larger commercial enterprises. Policy instruments must therefore account for differences in farm size, market structure, geography and access to capital.
Agricultural trade policy determines how farm products and agricultural inputs move across international borders. Governments can use tariffs, quotas, export restrictions, import standards, subsidies and trade agreements to influence agricultural trade. These measures can protect domestic producers or consumers under particular policy objectives but can also affect international prices and trading relationships. Agricultural trade policy is therefore closely linked to foreign policy and international negotiations.
Trade rules can also influence domestic agricultural policy because support measures may affect competition between domestic and foreign producers. The OECD's comparative agricultural policy analysis considers the interaction between domestic support and market conditions, helping distinguish policies that raise domestic market prices from those that provide direct transfers. Agricultural policy must therefore be understood within an international food system rather than solely as a domestic farming programme.
Agricultural policy also covers research, innovation and technology. Governments can fund agricultural research into crop varieties, animal health, soil management, irrigation, mechanisation, biotechnology, digital agriculture and climate resilience. Public research can address problems where benefits are widely distributed and private investment may be insufficient. Extension services can help farmers adopt new techniques by transferring knowledge from research institutions to farms. Technology policy can also influence productivity and resource efficiency, although adoption depends on costs, farm size, infrastructure and skills.
Agricultural innovation is increasingly important because farmers must respond to changing climate conditions, water constraints, market demands and environmental requirements. Agricultural policy therefore includes knowledge and innovation systems as well as financial support. The long term productivity of agriculture depends not only on current subsidies but also on research, human capital, infrastructure and the capacity of farmers to adopt improved practices.
Agricultural policy has developed from traditional concerns about food production and farm incomes into a much broader policy field involving markets, rural communities, environmental sustainability, food security, trade and technological change. Modern agricultural policy is increasingly evaluated using comparable indicators that distinguish market price support, output payments, input support and other forms of intervention. The OECD's 2025 monitoring work demonstrates the diversity of agricultural policy instruments across countries and the importance of analysing both their size and structure.
Agricultural policy therefore cannot be reduced to a simple question of whether farmers receive subsidies. It encompasses the institutional framework within which agriculture operates, including market rules, environmental requirements, research systems, infrastructure, trade arrangements, risk management and rural development. Its effects can extend to food prices, land use, environmental quality, rural employment, international trade and government expenditure, making agriculture a highly interconnected area of public policy.
