The differences among the land use change which will be described the structure of the changesin the uses of land from one type to another – and explains why these changes occur, what causes thesechanges, what are the mechanisms of change. Changes in the land use and the biodiversity are thought tobe five major causes of loss of agricultural biodiversity a) policies that promote/support homogenizedmonocultural high-chemical-input farming systems (such as subsidies, credit policies, etc..) ; b)agricultural/rural development programs that support conventional industrial patterns of uniformmonocultural development and reduce biodiversity; c) pressures by private sector interests thatperpetuate the sales and use of uniform seeds and related chemical inputs; d) inequities in thedistribution of and access to resources (including genetic resources); e) lack of participation of farmersand stewards of agrobiodiversity in decision-making and program development in agriculture; and f)neglect (or suppression) of local and indigenous knowledge about genetic resources and biodiversity,along with reductionist and uni-disciplinary scientific paradigm.
