Description: General changes in crop and livestock production systems, e.g. more efficient production methods to create higher production per unit of input, or other systems like organic farming
Is implemented in: Agricultural economy


Associated policy response component

Component: Land and biodiversity policies
Page: Land and biodiversity policies/Agricultural production system

Effects of this policy intervention on components

Component: Agricultural economy

Effect : Effect of this bunch of interventions is a change in the relation between the use of external inputs (capital), land and labour. For livestock systems the intervention can result in the use of more feed instead of grazing. For cropping systems it could, for example, express the use of more fertilizer to increase yields (closing the yield gap).

Component: Nutrients

Effect : intervention may be increased fertilizer use, or fertilizer use efficiency ...

Component: Water

Effect : Increasing the productivity of crops by converting rainfed to irrigated agriculture will have an effect on the irrigation water demand in the region. Extracting more water for irrigation will have an effect on downstream water availability and can increase water stress in the region.

Component: Aquatic biodiversity

Effect : On one hand the increase of productivity increases nutrient leaching to water bodies, on the other hand a smaller agricultural area is needed, reducing the pressures from agriculture.

Component: Terrestrial biodiversity

Effect : Impacts terrestrial biodiversity in two ways: 1) a smaller agricultural area decrease habitat loss and 2) it increase intensity of the agricultural area and consequently the biodiversity value of those areas.

Component: Ecosystem services

Effect : Increase intensity of the agricultural area, reduces nature on agricultural area thereby negatively influencing the ES dependent of nature (e.g. flood and erosion protection, pest control and pollination). While systems like organic farming contain more nature on agricultural areas and thereby positively influencing ES.
