Soil salinity encroachment is an increasing concern in many irrigated lands, because of the undesirable effects of soluble salts on agricultural production and on water quality.
Despite this potential for carbon storage, the implication of woody biomass changes on carbon stocks are highly uncertain and influenced by variety of conditions including the vegetation composition prior to encroachment, soil characteristics, disturbance regimes, land management, and climatic factors [16].

We tested the scaling effects of proximate desertification drivers (i.e. soil erosion, bush encroachment and grazing pressure) on soil nutrients in northeastern Tanzania.
This brief summary shows that many of the main environmental problems in Uganda are simultaneously part of other policy domains, such as agriculture (erosion and soil fertility), forestry (encroachment and charcoal burning), and health (water, solid waste, and sanitation).
Underdevelopment, soil erosion, sand dune encroachment, a chronic shortage of water – these all keep people poor and scrabbling to survive.
However, the influence of shrub encroachment on soil architecture is not well understood.
How an invasive nitrogen fixing tree changes the nutrient dynamics in the soil and facilitates further encroachment by other non-native plants.
To assess hydrological consequences of mesquite encroachment, the Soil and Water Assessment Tool (SWAT) was applied to simulate progressive mesquite encroachments in the upper San Pedro watershed (U.S./Mexico).
Woody encroachment significantly decreased soil δ15N throughout the entire soil profile, and created horizontal spatial patterns of soil δ15N that strongly resembled the spatial distribution of woody patches and were evident within each depth increment.
