This thesis deals with the European Union's food self-sufficiency. The aim is to try to assess the impact of EU agricultural policies on food sovereignty of Member States and countries outside the EU. The work will evaluate the production of food self-sufficiency in the European Union and the EU for different types of production. The work will assess the impacts of agricultural policies on the Union's agricultural production and international trade. International trade can be used to ensure self-sufficiency, so it is also included in the work. The work will also focus on the restrictions under the WTO and trade between the EU and the rest of the world. In addition to assessing the impact of the policies the work will also deal with future developments.
