Abstract: A direct relationship between abnormally rapid global warming and the CO2 produced by the exploitation and human uses of fossil fuels (coal, oil, natural gas, peat) is the basis of the recommendations made by the Intergovernmental Panel of Experts on Climate Change (the IPCC group) to fight against a worrying climatic drift in the next few decades. The IPCC mechanism of global warming is mostly based on radiative forcing and does not take into account ice melting and water evaporation as temperature controlling physical phenomena. Although, more and more scientists argue against the consensual IPCC’s vision, what is missing is opposition of another mechanism. The aim of the article is to propose an alternative mechanism derived from the analysis of facts and factors that contribute to warm the Earth. Starting from the fact that the Sun has been heating the planet for billions of years without dramatic drift other than fluctuations, it is shown that the environment is heated from natural sources (Sun, volcanoes) and by anthropogenic heat release. Anthropogenic heat is mostly composed of residual or waste heat coming from the production and the uses of energy necessary to satisfy human needs in work. To avoid the complexity of phenomena occurring in the atmosphere, the discussion was mostly based on examples taken from the current life to make the involved sciences clearer. Two major facts are emphasized. First, if there are natural and anthropogenic sources of heat energy on Earth, heat is a unique physical phenomenon. Second, heating by natural sources is sequential (day and night, summer and winter) whereas anthropogenic heating is almost permanent. This new vision leads to a new mechanism based on the physical and thermal properties of water and of solid-liquid-gas interphase equilibria involving exchanges of matter and heat. According to this mechanism, the temperature and ocean level rises should be smaller than predicted by the IPCC group but climatic events (winds, storms, hurricanes, tornadoes, streams, etc.) that are involved in the averaging of opposite local climates (dry and wet, droughts and floods, cold and hot, etc.) should increase in strength and frequency. It is concluded that minimizing anthropogenic heat release should be more efficient than fighting the sole CO2 to keep the drift of climatic events within acceptable limits.

Abstract: This paper examines noble examples of forestry biomass power plants located in Inner Mongolia Autonomous Region of China, which not only bring in with economic benefits to the people, but also encourage them to plant more and more shrubs, trees, and plants in order to reduce desertification. In addition, as a case study, future utilization potential bioenergy output of mobilizing sandy areas in Naiman Banner County was estimated in this study. Our result shows that with an average transmission distance of 50 km, the collectable biomass resources can produce electric power of 20~30 MW depending upon the efficiency of thermal conversion. This paper address different types of forest residues and energy from various biomass sources, highlight the advantage and shortcoming of each type. It can provide over 543 tons of fuels at least for the biomass power plant every day, which can fully satisfy the needs of power generation of the power plant. At present, the area of sandy plants in Naiman Banner has exceeded by 200 km2 every year, and desertification has been reduced effectively from 6,793.06 km2 (83.71%) in 2007 to 5,284.35 km2 (65.31%) in 2017. The desertification in Inner Mongolia Autonomous Region of China can be solved and minimized by proper harnessing the substantial forestry biomass power plants available in the Naiman Banner County. The energy conversion process from the biomass and the type of energy required plays a vital role in identifying the type of biomass required in this sustainable example of forestry biomass power plants. Its successful practice of utilizing local resources to generate power was discussed through five important questions.

Abstract: Long year cultivations under sugarcane production causes soil degradation and subsequently results in to change of soil properties. However, information on the effect of long year cultivation of sugarcane on soil physicochemical properties is scanty. A study was conducted in 2020 at Finchaa Sugar Estate to investigate the status of selected physicochemical properties of soil under mechanized sugarcane cultivation for different years. In this line soil samples were collected from 0-30 and 30-60 cm layers of long year cultivated, short term cultivated and virgin land uses for laboratory analysis. The result of this study showed that the highest bulk density value of soils for long year sugarcane cultivated fields under low organic matter content induced soil compaction and the bulk density and total porosity parameters of all crop land fields were out of optimum range for sugarcane production. The available water holding capacity of the surface soils of the study area was in the range of high class for all long term cultivated fields and optimum for sugarcane production. In terms of organic carbon, total nitrogen and available phosphorus contents the fertility status of soils was low. From these findings one can conclude that the low soil porosity and high soil bulk density values of long year sugarcane cultivated land indicates presence of soil compaction and sustainability problem for sugarcane production in the estate. Low organic matter, total nitrogen and available phosphorus noted under the cultivated land may cause sustainability problem to sugarcane production in the estate. To maintain sustainability of sugarcane production in the estate soil management practices that can increase soil organic matter, total nitrogen and available phosphorus is helpful. Therefore, to develop a more general recommendation further research studies are needed.
