The total of cropland and permanent meadows and pastures.

Agricultural land and associated surface water is equivalent to the 1993 SNA category “land under cultivation” (AN.2112) except for the qualification on recreational land (see recreational land) and the exclusion of plantations. The SEEA goes beyond the 1993 SNA in identifying specific sub-categories of agricultural land: cultivated land, pasture land and other agricultural land.

Agricultural landscapes can be described in terms of the three elements: structure, which concerns the interaction between environmental features, land-use patterns and human-made objects; functions, which are the provision of environmental services for farmers and society; and the values society puts on agricultural landscapes and the costs of maintaining and enhancing landscape provisions by agriculture. Because the underlying human and natural processes are subject to change and evolution, landscapes are "dynamic systems".

Clandestine employment is a sole or secondary gainful non-casual occupation that is carried out in violation of provisions set by legislation. In particular, it is characterized by non-compliance with labour standards and social security provisions on the part of the employer. Strictly speaking, remunerated work, which is not protected through contributions to the social security system, should be considered clandestine. However, there are different views of what constitutes clandestine labour in developed and developing countries, reflecting the strength and effectiveness of the relevant legal provisions in each country. Much clandestine employment is in the informal economy. However, clandestinity cannot always be equated with informality. Informal employment is more likely to be considered clandestine in the developed countries, whereas in most developing countries, where the majority of people may live in traditional social contexts and may not even be aware of national legislation, informal productive activities are not usually thought of as clandestine.
