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.

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.

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.

Urban ecosystem services (ES) contribute to the compensation of negative effects caused by cities by means of, for example, reducing air pollution and providing cooling effects during the summer time. In this study, an approach is described that combines the regional biotope and land use data set, hemeroby and the accessibility of open space in order to assess the provision of urban ES. Hemeroby expresses the degree of naturalness of land use types and, therefore, provides a differentiated assessment of urban ES.

Against the background of climate change, current and future provision of ecosystem services (ES) will also change. The recording of current provision potentials and its development in future is important for adapted regional planning. ES assessments are frequently carried out in the context of expert-based surveys, which have, however, revealed little information to date about uncertainties. We present a novel approach that combines the ES matrix assessment with the Delphi approach, confidence ratings, standardized confidence levels, and scenario assessment.

The effects of subsidies on the development of organic farming (OF) in the Czech Republic and in some selected EU countries are analysed in this article. The level of subsidies for OF in the Czech Republic is continuously increasing. In 1998, the total amount of subsidies was 48 million CZK, whereas in 2004, it increased to nearly 277 million CZK. The increase of subsidies led to an increase in the number of organic farms as well as the area under OF.

Since 1995, experiences have been gathered with the calculation of National Greenhouse Gas Inventories in Germany. Because only marginal changes of the total forested area occur in Germany, relevant changes of the balance of greenhouse gases in the forest sector are related to forest management. It was found that the increment of wood by far exceeds the harvested timber volume. Therefore, forests in Germany currently represent a significant sink for carbon (8-9 Mt C per year).
