Fine particulate matter (PM₂.₅) is the major air pollutant in Beijing, posing serious threats to human health. Land use regression (LUR) has been widely used in predicting spatiotemporal variation of ambient air-pollutant concentrations, though restricted to the European and North American context. We aimed to estimate spatiotemporal variations of PM₂.₅by building separate LUR models in Beijing. Hourly routine PM₂.₅measurements were collected at 35 sites from 4th March 2013 to 5th March 2014.

In the conditions of the Republic of Belarus there was examined transformation of approaches to the estimation of the role and place of land resources in social-economic development of society. There was marked the increased understanding of land use planning problems in the context of increasing its intensity and important problem of stable development of rural areas in modern world. There were established the problems of increasing ecological-economic efficiency of land use.

In Central Asia, water is a particularly scarce and valuable good. In many ecosystems of this region, the vegetation development during the growing season is dependent on water provided by rainfall. With climate change, alterations of the seasonal distribution of precipitation patterns and a higher frequency of extreme events are expected. Vegetation dynamics are likely to respond to these changes and thus ecosystem services will be affected.

Karst rocky desertification (KRD) is a type of land degradation especially prominent in southwest China. This article analyzes the anthropogenic driving forces of KRD at two scales: rural locality and its macro socio‐economic circumstances. At the rural locality scale, the intensive human pressure on land because of a large and fast growing population and unsustainable land use are identified to be the reason for KRD. However, more radical driving forces lie in the farmers' disadvantages in social‐economic circumstances, which compel them to overuse rural land.

Internal territorialisation or the formalisation of forest rights has led to increased state ownership in many countries, often ignoring traditional or customary tenure and land use. Because of its roots in a formal government process, the disjuncture between formal rights and local practices may be seen as unproblematic to policymakers, even though it harms the livelihoods of marginalised forest dwellers.

Accurate and timely information about the geographic distribution of irrigated cropland is important for a range of applications including crop assessments, water resources management, drought monitoring, and environmental modeling.

The breakdown of socialism caused massive socio-economic and institutional changes that led to substantial agricultural land abandonment. The goal of our study was to identify the determinants of agricultural land abandonment in post-Soviet Russia during the first decade of transition from a state-controlled economy to a market-driven economy (1990–2000). We analyzed the determinants of agricultural land abandonment for approximately 150,550km² of land area in the provinces (oblasts) of Kaluga, Rjazan, Smolensk, Tula and Vladimir in European Russia.

This study used linear programming (LP) to analyse land-use alternatives in the traditional Umbundu farming system in the Angolan central highlands. Farmers of the region have traditionally produced maize and pulses for subsistence and vegetables and timber as cash crops. Different pasture and forest fallow rotations are used along catena production sites. The system is labour-intensive and uses animal traction. LP problems were formulated and solved for a baseline land-use alternative, improved diet alternative and maximal timber production alternative.

Land areas in collective ownership or use are traditionally referred to as commons. Through history, the common use and ownership has been a widespread means of regulating the use of natural resources. Changing economic conditions and technology spawned a process however where land use rights and landowner rights aggregated into the modern form of private ownership of individual farms with full management and owner rights. This process had obvious rationales in terms of production of marketable agricultural products.

This paper examines environmental disturbances related to energy development in the Orenburg region through a two-pronged approach. First, it ranks environmental performance per 25 administrative districts based on multidimensional clustering of 10 diagnostic indicators. Second, it examines land-use and land-cover (LULC) patterns in nine western administrative districts by classifying Landsat imagery and quantifying surface disturbance for the year 2001. Spatial analysis and descriptive statistics help identify the most disturbed administrative units.

We estimate a system of equation model to understand the factors that influence the loss of agricultural land to non-agricultural uses in the Southeast United States. This is done by analyzing the complex relationship between population, employment, and agricultural land density for the 1990–-2000 period. From the results, it can be noted that growth in employment over time and the expansion of residential housing have to be compromised with the agricultural sector on the use and allocation of land.
