Couture ; CIHEAM-IAMM (Montpellier, France) ; Pôle Foncier (Montpellier, France) | 2022Just like climate hazards, land degradation is the result of human activities that overexploit ecosystems. Yet, there are very few empty places where no property rights to land and other natural resources exist. Ecological interventions usually [...]Actes de Congrès ou Communication isolée
M. Requier-Desjardins | 2011Valuation of land and land degradation question the value of natural capital in relation with ecosystem services; it is often quantified using exchange values of services or substitutes. Resilience broadly deals with the capacity to absorb a dis[...]Actes de Congrès ou Communication isolée

C. Ruau ; V. Naipal ; N. Gagnaire ; C. Cantero-Martínez ; B. Guenet ; B. Gabrielle |Soil erosion poses a significant threat to agricultural production worldwide, with a still-debated impact on the current increase in atmospheric CO2. Whether erosion acts as a net carbon (C) source or sink also depends on how it influences green[...]Article
La dégradation des terres est un problème préoccupant et dactualité dans plusieurs régions du monde. Il représente toujours un thème de recherche dactualité en géographie. Cet intérêt prend de limportance surtout avec lavènement du changemen[...]Article

Kosmas |The impact of simulated future climate change on land degradation was assessed in three representative study sites of Thessaly, Greece, one of the countrys most important agronomic zones. Two possible scenarios were used for estimation of futur[...]Article
Agriculture has been identified as one of the main drivers of environmental degradation in the European Union (EU). It can have negative impacts on air, water, soil and biodiversity. The condition of agroecosystems is affected by soil degradatio[...]Article

Rodrigues |The transition zone between the Tellian and Saharan Atlas of the Tiaret region in Algeria is believed to be undergoing land degradation processes because of the increase in population needs, which causes a weakening of the biological potential a[...]Article
Conversion of native lands into agricultural use, coupled with poor land management practices, generally leads to changes in soil properties. Understanding the undesirable effects of land-use and land-cover (LULC) changes on soil properties is e[...]Article
Salinization is a major soil degradation threat in irrigated lands worldwide. In Portugal, it affects several pockets of irrigated agricultural areas, but the spatial distribution and intensity of soil salinity are not well known. Unlike convent[...]Article
Soil, a non-renewable resource, sustains life on Earth by supporting around 95% of global food production and providing ecosystem services such as biomass production, filtration of contaminants and transfer of mass and energy between spheres. Un[...]Article
