Agriculture, largely based on livestock, has traditionally been the main occupation in the central and western parts. There are a mix of large and small farm businesses, and a thriving dairy sector in the Vale of Clwyd. Many of the towns have livestock markets and the farming industry supports farm machinery merchants, vets, feed merchants, contractors and all the ancillary trades connected with agriculture. With their incomes on the decline, farmers have found opportunities in tourism, rural crafts, specialist food shops, farmers' markets and value-added food products.
