Many organisms in the deserts already are near their tolerance limits, and some may not be able to adapt further under hotter conditions. Arid to semi-arid sub-regions and the grassland areas of eastern and southern Africa, as well as areas currently under threat from land Patient degradation and desertification, are particularly vulnerable. [ 7IPCCREGION 0 MCLH 03/08/2013 ]

Furthermore, severe droughts will also cause increased Degree degradation of water quality Patient , greater risk of eutrophication and extensive harm to aquatic ecosystems. [ 5CANADAICC 0 MCLH 03/08/2013 ]

The remainder of the carbon dioxide emissions comes from human land use activities -- ranching, agriculture and the clearing and degradation of forests Patient . [ 6CANADAQFP 0 MCLH 03/08/2013 ]

These stresses have led to problems of land Patient degradation, salinization, and woody weed invasion. [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]

We also need to consider the synergy between greenhouse gas mitigation strategies and the mitigation of other environmental externalities, such as local air pollution, urban congestion, or land and natural resource Patient degradation. [ 13IPCCSTABILISATIONDESGAZ 0 MCLH 03/08/2013 ]

Land Patient degradation problems and limited water supplies restrict present agricultural productivity and threaten the food security of some countries. [ 7IPCCREGION 0 MCLH 03/08/2013 ]

A critical research need is to assess whether resource Patient degradation will significantly increase the risks faced by vulnerable agricultural and rural populations [ 3IPCCCONSEQUENCE 0 MCLH 03/08/2013 ]

These ecosystem changes are primarily due to factors such as changing land-use patterns, and the degradation of many ecosystems primarily due to soil Patient degradation, water quantity and quality degradation, habitat loss, modification and fragmentation, selective exploitation of species, and the introduction of non-native species. [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]

Essentially, natural catastrophes or environmental Patient degradation often affect the regions in which they occur. [ JACLET 0 MCLH 03/08/2013 ]

These sources are also linked to degradation of air quality Patient and acid deposition. [ 11IPCCBILAN2001 0 MCLH 03/08/2013 ]

They include land-clearing, decreased local air quality and affected water and vegetation as a result of drilling, moving of earth and the grading and leaching of metals from mining residues, all of which indirectly may also result in habitat Patient degradation. [ 5IPCCDYOXYDE 0 MCLH 03/08/2013 ]

However, deforestation activities, forest Patient degradation and agricultural land mismanagement also add large amounts of carbon dioxide emissions - between 2 and 9 billion tonnes - each year. [ 6CANADAQFP 0 MCLH 03/08/2013 ]

In addition to climate change mitigation benefits, slowing deforestation and/or forest Patient degradation could provide substantial biodiversity benefits. [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]

High-latitude coasts will experience added impacts related to higher wave energy and permafrost Patient degradation. [ GREENFACTS 0 MCLH 03/08/2013 ]

More frequent floods and droughts, with floods Cause increasing sediment loads and causing degradation of water quality Patient III some areas. [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]

Key environmental pressures relate to biodiversity, landscape, soil, land, and water Patient degradation ( largely due to pollution Cause ). [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]
