Wales [SEP] Economy
Poor-quality soil in much of Wales is unsuitable for crop-growing so livestock farming has traditionally been the focus of farming. About 78% of the land surface is harnessed for agriculture. The Welsh landscape, with its three national parks and Blue Flag beaches, attracts large numbers of tourists, who bolster the economy of rural areas. Wales like Northern Ireland has relatively few high value-added employment in sectors such as finance and research and development, attributable in part to a comparative lack of 'economic mass' (i.e. population) – Wales lacks a large metropolitan centre. The lack of high value-added employment is reflected in lower economic output per head relative to other regions of the UK – in 2002 it stood at 90% of the EU25 average and around 80% of the UK average.
