It studies the preconditions of creation, functioning of farms in Ukraine and foreign countries. In the course of the study revealed that over the years 1990-2015, the number of farms increased from 332 to 54 302 is 915, 40 thousand hectares of land. For a specified period on one farm had between 12.0 to 78.8 ha of agricultural land (the most notable growth occurred in the period from 1990-1995, he was almost 100 times).
Despite this, farming did not become efficient producers of agricultural products.

There is a growing recognition of the contribution that privately-owned land makes to conservation efforts, and governments are increasingly counting privately protected areas (PPAs) towards their international conservation commitments. The public availability of spatial data on countries’ conservation estates is important for broad-scale conservation planning and monitoring and for evaluating progress towards targets.

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.

This opinion paper discusses urban lawns, the most common part of open green spaces and urban green infrastructures. It highlights both the ecosystem services and also disservices provided by urban lawns based on the authors’ experience of working within interdisciplinary research projects on lawns in different cities of Europe (Germany, Sweden and Russia), New Zealand (Christchurch), USA (Syracuse, NY) and Australia (Perth).

The research on wind regimes and the wind protection mechanism of sand-fixing plants has mainly relied on wind tunnel experiments; few observations have been made in the field. At the same time, airflow around individual standing vegetation elements and communities is relatively lacking in alpine semi-arid deserts. Therefore, this paper selected 10-year-old Hippophae rhamnoides (sea buckthorn) on sandy land on the eastern shore of Qinghai Lake as the study object.

The ongoing global deforestation resulting from anthropogenic activities such as unsustainable agriculture and surface mining threatens biodiversity and decreases both soil carbon and above-ground biomass stocks. In this study, we assessed soil properties and below- and above-ground biomass attributes in a restored former gravel mine area in Ghana two decades after active restoration with potted plants and fresh topsoil.

A singular and modest activist action, a temporary park created in San Francisco, grew into the global urban Park(ing) Day (PD) phenomenon. This tactical urbanism event not only expanded to be annually celebrated in thousands of parking lots all over the world but became an inspiration for urban planning and policy changes. The permanent rendition of Park(ing) Day, parklets, resulted from the movement but did not stop the spread of PD itself.

Historic urban landscapes (HULs) are composed of layers of history and memories that are embedded in physical monuments, buildings, and memorials. Physical built fabric stores both personal and cultural memory through long association with communities. Rapid changes due to demolition and redevelopment change the nature of these places and, in turn, affect these memory storages. This paper investigates whether historical city inhabitants consider cultural memories important when managing their HULs.

Forest conversion to agriculture can induce the loss of hydrologic functions linked to infiltration. Infiltration-friendly agroforestry land uses minimize this loss. Our assessment of forest-derived land uses in the Rejoso Watershed on the slopes of the Bromo volcano in East Java (Indonesia) focused on two zones, upstream (above 800 m a.s.l.; Andisols) and midstream (400–800 m a.s.l.; Inceptisols) of the Rejoso River, feeding aquifers that support lowland rice areas and drinking water supply to nearby cities.

Based on the background of the change in the urban–rural relationship in Guangdong Province, this paper constructs an analysis framework of urban and rural coordination development. Using the data of 19 administrative units above prefecture level in Guangdong Province, this paper studies the space–time evolution of urban and rural coordination development during 2000–2015 through Principal Component Analysis (PCA) and Exploratory Spatial Data Analysis (ESDA) and explores the influencing factors and driving forces behind it.
