Land degradation is a global issue receiving much attention currently. In order to objectively reveal the research situation of land degradation, bibliometrix and biblioshiny software packages have been used to conduct data mining and quantitative analysis on research papers in the fields of land degradation during 1990–2019 (data update time was 8 April 2019) in the Web of Science core collection database. The results show that: (1) during the past 20 years, the number of papers on land degradation has increased.

The ejido system, based on communal land in Mexico, was transformed to private ownership due to neoliberal trends in the 1990s. Based on the theory of stakeholders being agents of change, this study aimed to describe the land policies that changed the ejido system into private development to show how land tenure change is shaping urban growth. To demonstrate this, municipalities of San Andrés Cholula and Santa Clara Ocoyucan were selected as case studies.

The current paper examines the legitimacy dilemmas that rise from local governments’ direct policy instruments and market interventions. It takes the case of public land management strategies. The paper argues that current societal challenges—such as energy transition, climate change and inclusive urban innovation—require planning practices to be more effective. Direct government instruments such as direct market interventions have proven to significantly reduce the implementation gap of planning practice.

At the 2018 meeting of the Permanent European Conference for the Study of the Rural Landscape (PECSRL), that took place in Clermont-Ferrand and Mende in France, the Institute for Research on European Agricultural Landscapes e.V. (EUCALAND) Network organized a session on traditional landscapes. Presentations included in the session discussed the concept of traditional, mostly agricultural, landscapes, their ambiguous nature and connections to contemporary landscape research and practice.

Societies undergo continuous dynamics and change. By investigating the spatial structure of societal remains and material culture, we tried to get insights into the processes of their landscapes creation. Ritual practices, economic strategies, or the societal structure are stored in the landscape as a form of cultural contextualization. We presumed that changes of these will be strongest during phases of transformation and investigated to which degree transformation processes are mirrored in the spatial structure of material remains.

Ticks are responsible for the largest number of transmissions of vector-borne diseases in the northern hemisphere, which makes the risk from tick bites a serious public health problem. Biological scientific research and prevention studies are important, but they have not focused on the population’s perception of tick bite risk, especially at a spatial level.

In the context of the rapid development of renewable energy in Germany in the last decade, and increased concerns regarding its potential impacts on farmland prices, this paper investigates the impact of wind energy and biogas production on agricultural land purchasing prices. To quantify the possible impact of the cumulative capacity of wind turbines and biogas plants on arable land prices in Saxony-Anhalt, we estimate a community-based and a transaction-based model using spatial econometrics and ordinary least squares.

New approaches to collect in-situ data are needed to complement the high spatial (10 m) and temporal (5 d) resolution of Copernicus Sentinel satellite observations. Making sense of Sentinel observations requires high quality and timely in-situ data for training and validation. Classical ground truth collection is expensive, lacks scale, fails to exploit opportunities for automation, and is prone to sampling error.

Due to its cost-effectiveness and repeatability of observations, high resolution optical satellite remote sensing has become a major technology for land use and land cover mapping. However, inventory compilers for the Land Use, Land Use Change, and Forestry (LULUCF) sector are still mostly relying on annual census and periodic surveys for such inventories. This study proposes a new approach based on per-pixel supervised classification using Sentinel-2 imagery from 2016 for mapping greenhouse gas emissions and removals associated with the LULUCF sector in Wallonia, Belgium.
