Long-term impact of rainfed agricultural land abandonment on soil erosion in the Western Mediterranean basin

Land abandonment is widespread in the Mediterranean mountains. The impact of agricultural abandonment results in a shift in ecosystem evolution due to changes in soil erosion, but little is known about long-term soil and water losses. This paper uses 11 years of measurements in two paired plots (abandoned vs control) with four subplots to determine how soil and water losses evolved after abandonment within an agricultural parcel. For two years (2004–2005) both plots were under tillage, and after 2006 one plot was abandoned.

Simulating and delineating future land change trajectories across Europe

Journal Articles & Books

Europe

Explorations of future land use change are important to understand potential conflicts between competing land uses, trade-offs associated with particular land change trajectories, and the effectiveness of policies to steer land systems into desirable states. Most model-based explorations and scenario studies focused on conversions in broad land use classes, but disregarded changes in land management or focused on individual sectors only.

A global map of mangrove forest soil carbon at 30 m spatial resolution

Journal Articles & Books
december, 2018

With the growing recognition that effective action on climate change will require a combination of emissions reductions and carbon sequestration, protecting, enhancing and restoring natural carbon sinks have become political priorities. Mangrove forests are considered some of the most carbon-dense ecosystems in the world with most of the carbon stored in the soil. In order for mangrove forests to be included in climate mitigation efforts, knowledge of the spatial distribution of mangrove soil carbon stocks are critical.

Changes in soil organic carbon stocks after conversion from forest to oil palm plantations in Malaysian Borneo

Journal Articles & Books
december, 2018

The continuous rise in the global demand for palm oil has resulted in large-scale expansion of industrial oil palm plantations - largely at the expense of primary and secondary forests. The potentially negative environmental impacts of these conversions have given rise to closer scrutiny. However, empirical data on the effects of conversion of forests to industrial oil palm plantations on soil organic carbon (SOC) stocks is scarce and patchy.

Environmental cognitions mediate the causal explanation of land change

Journal Articles & Books
december, 2018

Causal explanations of land change are fundamental in land system science, yet existing findings are difficult to synthesize due to the imprecise terminology and the various analytical frameworks they have applied. This paper compares three existing conceptual frameworks, in terms of underlying driving forces and proximate causes, actors, and environmental cognitions, by aligning the relevant elements into a causal chain. We find that the elicitation of environmental cognitions helps in providing a detailed description of this causal chain.

Models meet data : Challenges and opportunities in implementing land management in Earth system models

Journal Articles & Books
december, 2018

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.

Scramble for Land Rights: Reducing Inequity between Communities and Companies

Global

Community land, crucial to rural livelihood around the world, is increasingly targeted by commercial interests. Its loss can lead to environmental degradation, increased rural poverty and land disputes that last for years. Without formal legal recognition of their land rights, communities struggle to protect their land from being allocated to outside investors.

Mapping and Assessment of Ecosystems and their Services. Soil ecosystems

Journal Articles & Books

Global

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.
