Adaptation to land degradation
Adaptation to land degradation is necessary when rehabilitation or restoration of the original state of the land is no longer possible or requires resources beyond the means of land users. The state of land degradation is thus “accepted” and land management is adapted to the degradation. Examples include adapting to soil sa-linity by introducing salt-tolerant plants, or climate change adaptation.

There are three elements to agrobiodiversity: (a) the overall range of different crops and animals, (b) the diversity of crops and animals within a particular farming system, and (c) the overall biodiversity of both cultivated and natural species within a farming system. Sustainable land management can help maintain and build up levels of biodiversity in all ecosystems.

It is the ratio of the number of livestock units (LSUs) (converted from the number of animals using standard coefficients) per hectare of fodder area. Through manure production, livestock can contribute to climate change (greenhouse gas emissions) and nutrient leaching into water and air. However, depending on farmer practices, a higher grazing livestock index does not necessarily mean environmental degradation. (http://ec.europa.eu/eurostat/statistics-explained/index.php/Glossary:Grazing_livestock_density_index)

Payment for Ecosystem Services (PES)
Also known as Payment for Environmental Services. Compensation or incentives paid to land owners or land managers in exchange for enhancement or maintenance of ecosystem services (e.g. clean water, biodiversity habitats, carbon sequestration capabilities) that would otherwise be decreased or threatened. These can be public payments to land owners, market trading schemes, or self-organized private deals (Liniger et al. 2017). The term PES applies to situations where one group of land users are the “custodians” of an ecosystem that has an impact on another group (or groups) situated off-site or downstream. The idea behind PES is that there is an implicit cost in maintaining the flow of ecosystem services, which should be paid for by those who benefit from them.

Land, often inaccessible and of poor quality, not used for production.
Windbreaks
A plantation usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted around the edges of fields on farms.
Woodland
A plant community in which, in contrast to a typical forest, the trees are often small, characteristically short-boled relative to their crown depth, and forming only an open canopy with the intervening area occupied by shorter vegetation, commonly grass. (Allen et al. 2011)
Zero grazing
Stall feeding (see above) where the livestock are not permitted to graze at all.
Zero tillage/ no-till/ direct drilling
A system whereby crops are planted into the soil without primary tillage beforehand. It is a way of growing crops or pasture from year to year without disturbing the soil through tillage. No-till is an agricultural technique, which increases the amount of water that infiltrates into the soil and increases organic matter retention and cycling of nutrients in the soil.
