In so far as the classification of land is concerned the position is that when the disadvantaged areas compensatory allowance schemes were first introduced in Ireland in 1975 the disadvantaged status of all land in the country had to be determined. In general land was classified as non-disadvantaged, less severely handicapped and more severely handicapped. The criteria concerning the designation of areas as disadvantaged are set out in EEC Directive 85/350. These criteria relate to (1) Infertile land: (a) less than 7.8% of area must be ploughed, (b) less than one livestock unit per forage hectare; (2) farm income: (a) family farm income per male farm worker must not exceed 80% of national average; (3) population: (a) not greater than 27 inhabitants per square kilometre, (b) minimum of 30% of working population engaged in agriculture.
