As a result of soil degradation, it is estimated that about 11.9-13.4% of the global agricultural supply has been lost in the past five decades. Besides, soil degradation is also associated with off-site problems of sedimentation, climate change, watershed functions, and changes in natural...
Theassessment oflanddegradationand restoration will also draw on the FAOGlobal SoilPartnership and theGlobal SoilBiodiversity Initiative. 对土地退化和恢复问题的评估还将借鉴粮农组织全球土壤伙伴关系和全球土壤生物多样性倡议的经验。 UN-2 The Subcommittee emphasized the importanceofEarth observation satellite dat...
Causes And Types Of Soil DegradationDatabasesGlobal AssessmentSoil is a valuable natural resource that in the short - term is nonrenewable and is difficult to reclaim when degraded. The use of soils on a sustainable basis requires that their capability to withstand the demands upon them is not ...
land degradation and food insecurity in many regions6. Low soil moisture (volumetric water content,θ) and high VPD are considered the two main drivers of plant water stress, but their relative importance in ecosystem water limitation is debated1,2,14,15. While the exchange of water between ve...
Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restor
Soil degradation is a mounting problem on many smallholder lands in developing countries. Economic analysis has been an important tool in addressing this problem, beginning with assessments of the financial attractiveness of investing in soil conservation works. Data compiled from 67 studies of the fina...
Permafrost degradation services for Arctic greening 2023, Catena Citation Excerpt : The mean total area of the cryosphere is estimated to be 68 × 106 km2, which corresponds to 13 percent of the surface area of the Earth (Hock et al., 2019). At present, research has begun to investigate ...
For example, the bottom-up approach used in this work showed accelerated rates of SE due to agriculture activities in several developing countries, which can lead to soil degradation, farmer income insecurity and deforestation for establishing new crop plantations in more fertile soils. The successful...
