resource; its qualities and value often have been built during decades or centuries. Land 
use planning needs to be in accord with protection policies with a view to safeguarding 
the land for future generations.
Agricultural production is based on plant growth, and mainly deals with production 
of food, livestock feed and fibres. The identification of soil, climate and water constraints 
to agricultural production, and the development of technologies that overcome these 
constraints, need to go hand in hand with the sustainable use of land resources. Land 
resources are managed with external inputs such as energy, plant nutrients and machinery 
to achieve production, which in turn affects the environmental quality of the land 
resources. Agricultural land use and land resources quality are linked to technological 
change and production practices, and influence farm and environmental programs.
Forestry and agro-forestry are providing products such as timber, fuel, fruits 
and medicines. Non-wood products (formerly called minor forest products) can be 
particularly important to the poor or to minority communities. The trees also provide 
services including food security, soil fertility, soil conservation, carbon sequestration 
and biodiversity protection. In European countries, for example, the Common 
Agricultural Policy promotes living hedges as structural landscape elements, and set-
aside land to control agricultural production and sequester carbon.
