In this study, we sought to analyze the pressures of the grassland ecosystem in China and explore practical countermeasures to protect grassland biodiversity. The prominent ecological problems in grassland biodiversity conservation included rapid population growth, economic development, resource exploitation and global climate change, among which human interferences strongly influenced the grassland ecosystem. Rapid population growth and economic development still severely restricted biodiversity conservation, but coal resource exploitation gradually developed a new serious pressure for grassland biodiversity. In addition, climate change further aggravated biodiversity loss. According to these pressures, we proposed several practical countermeasures such as readjusting the industrial structure, and relieving the pressures of grassland, and conducting near-natural restoration as well as carrying out ecological compensation. This study will provide the scientific reference for manager and policy-makers of grassland biodiversity conservation.

Based on the latest data, paper investigates the dynamics of global climate change and its impact on economic growth in the long-term. The notion of climate risk is considered. The main directions of climate risk management policies are analyzed aimed, first, at reducing anthropogenic greenhouse gas emissions through technological innovation and structural economic shifts; secondly, at adaptation of population, territories and economic complexes to the irreparable effects of climate change. The problem of taking into account the phenomenon of climate change in the state economic policy is put in the context of the most urgent tasks of intensification of long-term socio-economic development and parrying strategic challenges to the development of Russia.

Some economists argue that high population density and rapid population growth are not in themselves impediments to economic development. On the basis of a quantitative analysis of historical data, Simon Kuznets, for instance, concludes that, historically, rates of economic development have not significantly correlated, either positively or negatively, with rates of population growth. Similarly, E. E. Hagen observes that “nowhere in the world has population growth induced by rising income been sufficient to halt the rise in income. … The historical record indicates that rise in income in these societies has failed to occur not because something thwarted it, but because no force has been present to cause income to rise.

It’s complicated. Tropical diseases have unusually intricate life cycles because most of them involve not only a human host and a pathogen, but also a vector host. The diseases are predominantly tropical due to their sensitivity to local ecology, usually due to the vector organism. The differences between the tropical diseases mean that they respond to environmental degradation in various ways that depend on local conditions. Urbanization and water pollution tend to limit malaria, but deforestation and dams can exacerbate malaria and schistosomiasis. Global climate change, the largest environmental change, will likely extend the range of tropical climate conditions to higher elevations and near the limits of the tropics, spreading some diseases, but will make other areas too dry or hot for the vectors. Nonetheless, the geographical range of tropical diseases will be primarily determined by public health efforts more than climate. Early predictions that malaria will spread widely because of climate change were flawed, and control efforts will probably cause it to diminish further. The impact of human disease on economic development is hard to pin down with confidence. It may be substantial, or it may be misattributed to other influences. A mechanism by which tropical disease may have large development consequences is its deleterious effects on the cognitive development of infants, which makes them less productive throughout their lives.

‘What is climate change?’ discusses what climate change is. Climate change is no longer just a scientific concern, but encompasses economics, sociology, geopolitics, national and local politics, law, and health just to name a few. Greenhouse gases (GHGs) play an important role in moderating past global climate. Why they have been rising since before the Industrial Revolution, and why are they now considered dangerous pollutants? Which countries have produced the most anthropogenic GHGs and how is this changing with rapid economic development? It is important here to consider the Intergovernmental Panel on Climate Change (IPCC) and how it regularly collates and assesses the most recent evidence for climate change.

Venezuela has experienced significant economic development during recent decades, although rapid population growth has partially offset economic gains. During the five-year period 1969-1973, the gross national product increased at an annual rate of 5.0 percent, which, coupled with population growth, yielded real per capita increases of 2.6 percent annually. Relatively smooth transition in the nationalization of the Venezuelan oil industry in 1976 presents a favorable assessment for the economy during the next decade. Yet while there has been notable progress in conventional economic indicators, there have been less rapid improvements in education, nutrition, and health. This paper examines past trends in Venezuelan population growth within the context of general social and economic development. Because of the importance of fertility in affecting population growth, particular attention is paid to fertility trends.

One of the main challenges of the future is the strengthening impact of environmental factors on economic development, in particular, environmental threats, climate change, waste minimization and reduction of СО2 emissions. At the present stage, achieving sustainable economic development has become an important item on the global agenda. The purpose of this article is to develop the theoretical foundations of the process of greening in the economy and substantiate practical approaches in Ukraine to overcome global climate challenges. To achieve this goal, the author used retrospective research methods, and abstract-logical, economic-statistical and systematic approaches. Based on the analysis of scientific works of foreign and domestic scientists, the article deepens the theoretical foundations of the concept of greening. In particular, it is established that this concept characterizes the improvement of environmental parameters of production through the introduction of technological, organizational and managerial innovations that increase the efficiency of natural resources, reduce man-made impact improve the quality of the environment and increase the level of environmental education and environmental culture of the population and industrial staff. The results of the study showed that in modern conditions the concept of sustainable dependence of the economy on environmental factors has been formed, which is supplemented by the problem of solving global challenges of mankind. This requires the introduction of new economic approaches to addressing the global challenges posed by climate change, among which the introduction of the principles of circular economy is important.

Based on field investigation and social-economical data, in combination with the 1992 and 2007 Landsat TM remote sensing images of Coastal Urban Belt in Liaoning, this paper analyzed the driving forces of landscape pattern in the study area. From 1992 to 2007, the landscape pattern in the study area experienced a significant change. The rapid population growth, economic development and infrastructure construction had exerted strong influences on these changes of landscape pattern, and thus leading to a deeper level of landscape fragmentation
