3.2.4.1. Agricultural land loss. A decrease in availability of land for agricultural purposes
may result in eroding the food base in the valley. This indicator is defined as the amount of
agricultural land lost to urban growth and was determined from the outputs of the spatial
simulation model.
3.2.4.2. Land marginality index. This is an indicator of land production potential and,
together with the previous indicator, it addresses food security concerns. Agricultural area
may expand on marginal lands, which would not result in a matching increase in
production. Such a situation may decrease the eco-efficiency of agricultural systems by
increasing input costs.
This indicator was calculated as:
