high-end watches and clocks. Swiss companies produce most of the world's high-end watches: in 2011 exports reached nearly 19.3 billion CHF, up 19.2% over the previous year. Watch manufacturing is mostly located around the Jura mountains, in the cantons of Geneva, Vaud, Neuchâtel, Bern, and Jura. Notable watchmaking firms include Rolex, Patek Philippe, Swatch, and Richemont. The watches go to Asia (55%), Europe (29%), Americas (14%), Africa and Oceania (both 1%). In 2011, Switzerland led the world by exporting over US$20 billion value of all types of watches, followed by Hong Kong, at under US$10 billion. China exported the highest number of watches by far in 2011. Industrial sector Switzerland has an extensive industrial sector, with globally competitive companies in various industrial sectors. Most noticeably, food processing like Nestlé, machines and robot manufacturers such as ABB, Bobst SA and Stadler Rail, chemicals for industrial and construction use like Sika AG, or military equipment such as Ruag. Switzerland also has one of the most competitive pharmaceutical industries in the world. Major Swiss pharmaceutical companies include Novartis and Roche. Agriculture Switzerland is highly protective of its agricultural industry. High tariffs and extensive domestic subsidisations encourage domestic production, which currently produces about 60% of the food consumed in the country. According to the Organisation for Economic Co-operation and Development (OECD), Switzerland is subsidising more than 70% of its agriculture compared to 35% in the EU. The 2007 Agricultural Program increased subsidies by CHF 63 million to CHF 14.092 billion. Protectionism acts to promote domestic production, but not to reduce prices or the cost of production, and there is no guarantee the increased domestic production is actually consumed internally; it may simply be exported, to the profit of the producers. 90 to 100% of potatoes, vegetables, pork, veal, cattle and most milk products are produced in the country. Beyond that, Swiss agriculture meets 65% of the domestic food demand. In 2016 the Swiss government spent about 5.5% of its total budget (over CHF 3.5 billion) on supporting food production. The first reform in agricultural policies was in 1993. Among other changes, since 1998 Switzerland has linked the attribution of farm subsidies with the strict observance of good environmental practice. Before farmers can apply for subsidies, they must obtain certificates of environmental management systems (EMS) proving that they: "make a balanced use of fertilizers; use at least 7% of their farmland as ecological compensation areas;
