World food production needs to double by 2050 to cater for population growth and evolving food habits. It faces the impacts of climate change on biodiversity, soil and water quality, and the demands of the global marketplace. EU farm policy has changed considerably in recent decades to help farmers face these challenges and respond to peoples' changing attitudes and expectations. EU agricultural policy covers a wide range of areas, including food quality, traceability, trade and promotion of EU farm products. The EU financially supports its farmers and encourages sustainable and eco-friendly practices, while also investing in the development of rural areas. EU institutions collaborate on food and farming policy-making, implementing, monitoring and evaluating it. National and local authorities implement the laws agreed at EU level. Through the EU budget, funds are made available to member states in accordance to rules set at EU level. The EU also monitors how laws are applied, how effective they are, and coordinates amendments. Agriculture and food related industries and services provide over 44 million jobs in the EU, including regular work for 20 million people within the agricultural sector itself. Thanks to its varied climate, fertile soil, the technical skills of its farmers and the quality of its products, the EU is one of the world's leading producers and exporters of agricultural products.
