Permafrost landscapes occupy 25% of the world’s land area. The formation, dynamics, and evolution of these landscapes are greatly controlled by permafrost processes and thus require special approaches to classification and mapping. Alases, pingoes, edoma, thermokarst mounds, stone streams, low-centre polygonal tundra, and other surface features are associated with the presence of permafrost. Permafrost degradation and greenhouse gas emission due to global climate warming are among the major potential dangers facing the world. Improvements in knowledge about permafrost landscapes are therefore increasingly important. This special issue, titled “Permafrost Landscapes: Classification and Mapping”, presents articles on classification, mapping, monitoring, and stability assessment of permafrost landscapes, providing an overview of current work in the most important areas of cold regions research.

Waste generation nowadays is rising in the world and it seems hard to prevent it. Solid Waste Management (SWM) has been a major problem worldwide in most of the fast growing towns and cities among the developing countries all around the world. Food waste and green waste constitute high volumes of municipal solid waste (MSW). The application of compost in the agricultural sector can contribute to sustainable soil health and other co-benefits. The compost produced from biological waste does not contain any chemicals unfavorable to living soil. The objective of this research was to calculate the greenhouse gas emission from the compost processed from the food and green wastes generated on-campus in Universiti Teknologi Malaysia (UTM) as a pilot project. The result indicated that the composting process promotes the university as a green campus by converting organic wastes into valuable products such as organic fertilizer.

238U Ratio

In natural water, as a rule, there is a violation of radioactive equilibrium in the chain 238U … → 234U → 230Th →. Groundwater usually has a 234U/238U ratio in the range of 0.8–3.0 (by activity). However, in some regions, the 234U/238U ratio reaches >10 and up to 50. Ultrahigh excesses of 234U can be explained by climatic variations. During a cold period, minerals accumulate 234U as a normal component of the radioactive chain, and after the melting of permafrost, it is lost from the mineral lattice faster than 238U due to its higher geochemical mobility. This hypothesis was tested using data on the isotopic composition of uranium in the chemo- and bio-genic formations of the World Ocean and large lakes, which are reservoirs that accumulate continental runoff. The World Ocean has the most significant 234U enrichments in the polar and inland seas during periods of climatic warming in the Late Pleistocene and Holocene. In the bottom sediments of Lake Baikal, the 234U/238U ratio also increases during warm periods and significantly exceeds the 234U excess of the World Ocean. Furthermore, the 234U/238U ratio in the water of Lake Baikal and its tributaries increases from north to south following a decrease in the area of the continuous permafrost and has a seasonal variation with a maximum 234U/238U ratio in summer. The behavior of 234U in large water reservoirs is consistent with the hypothesis about the decisive influence of permafrost degradation on the anomalies in 234U/238U ratios in groundwater.

Deforestation remains one of the most intractable environmental problems of today. About one third the size of the original forest cover has disappeared so far. Despite continuous efforts by the world community to curb this process, deforestation continues unabated in most parts of the world, with serious consequences for the human livelihoods, eco systems, and global climate. Pakistan also faces serious problem of depletion of its forest reserves. Approximately 39000 ha of forest are being cleared every year.1 If deforestation continues at this pace, it is feared that Pakistan will lose most of its forest within the next thirty to forty years. Being a forest poor country, with forest occupying less than 5 percent of total land area,2 protection of its forest resources is a vital task. Forest management faces many challenges in Pakistan. Forests face tremendous pressure, not only from a population of 160 million people for meeting their needs3 (be it only subsistence needs), but also from market forces which have seen soaring timber prices for many years now. Forest department is ill equipped to counter these challenges. It lacks human and financial resources, and relevant technical expertise.

Agricultural intensification is considered essential for meeting growing demand for food and biomass for energy purposes. Intensifying grasslands is under-represented, although it is a promising option given their large land area and relatively low management levels. This study quantifies the bioenergy potential from intensifying temporary grasslands in Europe and the integral greenhouse gas emission effects in 2030. We first conducted a literature review of intensification options for European grasslands and then applied the environmental impact assessment model MITERRA-Europe to implement the key intensification option of using multi-species grass mixtures. The results showed that 853 kha (or 8%) of temporary grassland could be made sustainably available for additional biomass production. This can be translated into a bioethanol potential of 23 PJ yr−1 and an emission mitigation potential of 5.8 Mt CO2-eq yr−1 (if conventional grass mixture from surplus temporary grassland is used for energy) or 72 PJ yr−1 and 4.0 Mt CO2-eq yr−1 (if surplus temporary grassland is used for grassy energy crops). Although the bioenergy potential is limited, the key advantage of intensification measure is that it results in a better environmental performance of temporary grasslands. This makes it a key option for sustainably producing bioenergy in areas with high shares of temporary grasslands.

China, with the biggest electricity system, now leads the world on its global share in electricity production and consumption, as well as greenhouse gas emission. However, its incomplete power system reforms left an uncoordinated development between the generator and the grid. Despite intensive investment and construction of power generation infrastructure, the lagging grid reform has become a bottleneck in the sector. The benefits of electricity sector reform, if designed and proceeded carefully, can be substantial.

The world is going through a very tough situation in terms of environment pollution. Many of the activities of human are creating huge pollution in the entire world. The weather and climate have been changing continuously due to a wide range of human factors. This emission of Greenhouse gases increases the atmospheric temperature gradually. This paper provides a critical perspective to the debate on various greenhouse gas emission in the world. This paper consists of three major areas of discussion. First part of the discussion is with Trends in global CO2 emission second part is global CO2 emission by sector. The last part of the discussion is the potential alternate option to reduce this Gas emission and its concerns for growth focus is discussed for further research. Most of the research papers focused about the solution to the reduction of greenhouse gas emission. Furthermore, in this paper I have focused on the review of Indian wind industries model and its major constraints faced by a wind turbine manufacturer. The result of this research paper is a solid base for further research on which parameter to be focused so that this industry can grow.

AbstractGood intentions by the middle class are not always well guided and do not always lead to measurable or significant results. For example, efforts to limit greenhouse gas emissions may hold broad appeal but can still have negligible impact. Therefore, it is suggested to embark on “Apollo projects”, which bundle the potential and willingness of the middle class. These projects should focus on the development of specific technologies, with economic advantages to support their spread throughout the world. Doing so will harness the middle class in support of greenhouse gas emission reductions in the gigaton-range. Such pan-national projects, for example, could address emission-free ship- or air-propulsion, the electrification of heating or of processes in the chemical industry.
