Matrix of environmental risks in sub-humid and humid mobile grazing sub-system - LGH1

Resource base | Risks and opportunities | Underlying factors
Water Quality | (-) Chemical pollution | Poor management of chemical inputs: e.g. for disease control
(-) Organic pollution of stream water | Poor management of animals wastes
Atmosphere Gas emission | (-) Increased Carbon dioxide emission | Use of Fire to maintain pasture
(+) Decreased rates of Carbon dioxide release to atmosphere | Carbon sequestration: Maintenance or restoration of natural or semi-natural ecosystems
Biodiversity Vegetation structure | (+) Good use of ground cover | Good grazing management: improved distribution of grazing pressure
(+) Improvement of ground cover | Animal trampling: improvement of grass tillering
(-) Excessive increase of tree and shrub density | Poor grazing management
(+) Maintenance of vegetal structure and open landscape | Good grazing management
Biodiversity Plant species | (+) Improvement of botanical diversity | Good grazing management
(-) Weed invasion | Invasive weed as a result of poor grazing management: Seed dissemination by animals (and humans)
Biodiversity Animal species | (+) Protection of wildlife and habitats | More effective protection of wildlife: Maintenance of natural or semi-natural ecosystems
(-) Reduction of wildlife and habitats | Poor protection of wildlife: Competition for food, water & space between livestock and wildlife
