Land Use Conflicts in the Energy Transition: Dutch Dilemmas

Journal Articles & Books
Diciembre, 2018
Netherlands

The transition from fossil to renewable energy needs changes in land use. The development of renewable energy sources introduce extra and sometimes new externalities, such as shadows and noise on landscape. There are governments who are experiencing difficulties when developing renewable energy sources especially when existing land owners (and others) start anticipating on those externalities. Therewith, land use conflicts have become a major issue for governments in meeting renewable energy policy objectives.

Nature-based solutions for flood-drought risk mitigation in vulnerable urbanizing parts of East-Africa

Journal Articles & Books
Diciembre, 2018

Urbanization and climate changes have direct impacts on ecosystems and the services they provide to society, thus influencing human well-being and health. Urban sprawl may conflict with ecosystem services, e.g. enhancing water-related stresses and risks of, e.g., droughts and floods, with significant economic, environmental and societal impacts. Such hydro-climatic extremes and their societal impacts are evident around the world. East Africa is a region with highly vulnerable populations to frequent floods and droughts.

Assessing impacts of soil management measures on ecosystem services

Journal Articles & Books
Diciembre, 2018
Europe

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.

Understanding the spontaneous spreading of stone bunds in Ethiopia : Implications for sustainable land management

Journal Articles & Books
Diciembre, 2018
Ethiopia

This study deals with the spontaneous spreading of stone bunds in the central Ethiopian highlands, i.e., the adoption and implementation of stone bunds by farmers on their own initiative. The study tests the hypothesis that spontaneously implemented stone bunds, as compared to stone bunds implemented by mass mobilization campaigns, are more integrated with other land management practices and lead to higher yields. Data are collected in the Girar Jarso woreda through field observations and household surveys.

Soilwater conservation : Dynamics and impact

Journal Articles & Books
Diciembre, 2018

Human needs like food and clean water are directly related to good maintenance of healthy and productive soils. A good understanding of human impact on the natural environment is therefore necessary to preserve and manage soil and water resources. This knowledge is particularly important in semi-arid and arid regions, where the increasing demands on limited water supplies require urgent efforts to improve water quality and water use efficiency. It is important to keep in mind that both soil and water are limited resources.

Is land fragmentation facilitating or obstructing adoption of climate adaptation measures in Ethiopia?

Journal Articles & Books
Diciembre, 2018

Land fragmentation is high and increasing in the Gamo Highlands of southwest Ethiopia. We postulate that this substantial land fragmentation is obstructing the adoption of sustainable land management practices as climate adaptation measures. To explore this, a mixed method study was conducted with emphasis on a multivariate probit model. The results indicate that farmers adapt to climate change and variability they perceive.

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

Journal Articles & Books
Diciembre, 2018
Spain

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
Diciembre, 2018
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
Diciembre, 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
Diciembre, 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
Diciembre, 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
Diciembre, 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.
