International Non-Governmental Organizations have popularized payment for ecosystem services (PES) because of their potential to simultaneously achieve rural development and ecological conservation goals (GEF Secretariat 2014). Despite their rapid diffusion, there is insufficient assessment of their potential implications for social and economic stratification (Redford and Adams 2009). Indeed, there is growing evidence that PES may reproduce or even exacerbate existing inequalities in social development and resource access (Kosoyand Corbera2010, Porras 2010).

Land degradation is a major challenge limiting crop production in Ethiopia. Integrated soil and water conservation is widely applied as a means to reverse the trend and increase productivity. This study investigated the effects of such integrated approaches at two sites, Jeldu and Diga, in Western Ethiopia. A split plot design with physical soil and water conservation in the main plots and agronomic practices in the sub plots was employed.

Bush encroachment is a matter of growing concern in the semi-arid regions of Namibia. Locally adapted, long-term solutions for land restoration must be elaborated. It is crucial that local scientists are empowered to map and monitor the degradation process themselves, our authors maintain.

Soil and water conservation (SWC) practices like that of erosion control and soil fertility measures were commonly practiced in the semiarid region of southern Mali since the 1980s. The SWC practices were mainly meant to increase water availability in the subsurface, reduce farm water runoff and gully formation and improve nutrient content of the soil, thereby increasing crop yield. Despite such efforts to promote at scale SWC practices, the landscape of southern Mali is still affected by high rates of runoff and soil erosion and low crop yield in farmers’ fields.

Only a few studies have quantified and measured ecosystem services (ES) specifically related to soil. To address this gap, we have developed and applied a methodology to assess changes in ecosystem services, based on measured or estimated soil property changes that were stimulated by soil management measures (e.g., mulching, terracing, no-till). We applied the ES assessment methodology in 16 case study sites across Europe representing a high diversity of soil threats and land use systems.

As the applications of Earth system models (ESMs) move from general climate projections toward questions of mitigation and adaptation, the inclusion of land management practices in these models becomes crucial. We carried out a survey among modeling groups to show an evolution from models able only to deal with land-cover change to more sophisticated approaches that allow also for the partial integration of land management changes. For the longer term a comprehensive land management representation can be anticipated for all major models.

Soil ecosystem services, as all ecosystem services (ESS), are fundamental for meeting societal needs such as food and energy provision and for overcoming societal challenges like climate change mitigation and adaptation. The MAES (Mapping and Assessment on Ecosystems and their Services) Soil Pilot aims to increase awareness on the importance of soil functions and related ecosystem services and to show their value. The pilot shows the need for protection, management and restoration of soil ecosystems and the need to make a more sustainable and efficient use of it.

Soil provides us with essential services. We grow our food in it, it filters rainwater before it reaches aquifers, it supports our buildings, it hosts diverse life forms. Europeans need multi-functional and healthy soils locally and globally to maintain this natural capital while satisfying the needs of a prosperous society. Soil must be safeguarded by urban and rural spatial planning and sustaining soil and land management based on applying the best available knowledge.

Removal of atmospheric carbon dioxide (CO2) combined with emission reduction is necessary to keep climate warming below the internationally agreed upon 2°C target. Soil organic carbon sequestration through agricultural management has been proposed as a means to lower atmospheric CO2 concentration, but the magnitude needed to meaningfully lower temperature is unknown. The authors show that sequestration of 0.68 Pg C year−1 for 85 years could lower global temperature by 0.1°C in 2100 when combined with a low emission trajectory [Representative Concentration Pathway (RCP) 2.6].
