|Description= | |Description=The wide range of environmental issues related to agriculture and forestry include distorted nutrient balances, biodiversity loss, greenhouse gas emissions from land use and land-use change, soil degradation, and water stress due to agricultural water demand. These issues can be addressed from a sector perspective focusing on the respective system (e.g., [[nutrient balances|nutrients]], [[water]], see the respective components). However, these issues are linked by demand for land-based products, and by land management. | ||
==Policy interventions== | |||
The IMAGE framework enables a systems approach to analyse policy interventions targeting the impacts of land use on biodiversity and climate change. To identify interventions that could reduce the impacts of agriculture and forestry on the environment, the system takes account of the chain linking demand for food, feed, wood, and bioenergy, to types of production systems and to landscape impacts. | |||
Policy interventions can target demand for commodities (Figure A), the production system, for instance, with respect to efficiency of natural resource use (Figure B and C), or a more systemic approach to regulating land use for different purposes within a landscape (Figure D). Regulation of land use implies managing the land resource base by designating areas to specific purposes, such as excluding protected natural areas from agricultural use, or preventing deforestation. Alternatively, regulation could be in the form of financial incentives to create value for currently non-market ecosystem services, such as emission reduction from deforestation combined with biodiversity conservation (e.g., {{abbrTemplate|REDD+}} schemes) and other forms of payment for ecosystem services ({{abbrTemplate|PES}}). | |||
While this section focuses on the impacts on biodiversity, climate change, water and nutrient balances, some policy interventions also have implications for other policy domains, such as food security, human health and animal welfare. | |||

Key policy issues
- How can land-use policies contribute to strategies for halting biodiversity loss and reducing greenhouse gas emissions?
- How can changes in consumption patterns contribute to achieving sustainability goals through changes in land use?
- What are the synergies and trade-offs between halting biodiversity loss, food security, reducing nutrient emissions, and reducing water stress?
