Large-scale reforestation can potentially bring both benefits and risks to the water cycle, which needs to be better quantified under future climates to inform reforestation decisions. We identified 477 water-insecure basins worldwide accounting for 44.6% (380.2 Mha) of the global reforestation potential. As many of these basins are in the Asia-Pacific, we used regional coupled land-climate modelling for the period 2041–2070 to reveal that reforestation increases evapotranspiration and precipitation for most water-insecure regions over the Asia-Pacific. This resulted in a statistically significant increase in water yield (p < 0.05) for the Loess Plateau-North China Plain, Yangtze Plain, Southeast China and Irrawaddy regions. Precipitation feedback was influenced by the degree of initial moisture limitation affecting soil moisture response and thus evapotranspiration, as well as precipitation advection from other reforested regions and moisture transport away from the local region. Reforestation also reduces the probability of extremely dry months in most of the water-insecure regions. However, some regions experience non-significant declines in net water yield due to heightened evapotranspiration outstripping increases in precipitation, or declines in soil moisture and advected precipitation.

With the rising environmental problems there are international movements towards sustainability and greening the built environments in order to mitigate the negative environmental impacts of buildings and human activities on environment and human health. This paper presents a range of K-12 Green Schools that were intentionally designed to utilize school building as a 3D-text book for Environmental Education (EE). The aim of this paper is to examine the methods and strategies of designing green school as a teaching tool through case study analysis of the selected schools. The cases provide a diversity of geographic locations, climates, green strategies and coasts. The research depends on the descriptive analytical approach for literature review; multiple-case study analysis to investigate the attributes of green schools that teach. The results revealed a set of approaches for utilizing green schools as a 3D-textbook for EE EQA - International Journal of Environmental Quality, Vol 39 (2020)

The need for plastic solutions has increased as a result of the expansion in the usage of plastic-based items, adding pressure to the waste management system. The use of plastics derived from petroleum, which significantly harm the environment, is being reduced with great interest. Substituting biodegradable plastic made from natural resources such as unprocessed agricultural waste, aquatic life, and even microbes for traditional plastics made through the petrochemical process is one way to address the problems. The worldwide bioplastics and biopolymer targets are the focus of all these initiatives. The focus of this study is on the sea grape, or Caulerpa lentillifera. The Caulerpa lentillifera plant, which is widely distributed along Sabah's east coast and in the Malacca Strait and is significant economically in Malaysia, was also mentioned. It possesses antibacterial qualities and is found in abundance there. The goal of the innovation project is to create biodegradable plastic from Caulerpa lentillifera and test the anti-microbial capabilities of the plastic. It is anticipated that this novel product will benefit society and have a high likelihood of being commercialized. Due to its remarkable biodegradability, the use of biodegradable plastic has recently become more popular. It is very simple to stretch and can lessen the environmental impact because it does not release carbon dioxide. Additionally, it does not produce a lot of hazardous emissions and has the potential to biodegrade into a natural component that blends into the soil. Additionally, biodegradable packaging has found use in several industries such as consumer goods and medical technology. The Sustainable Development Goals (SDGs) established by the United Nations, particularly SDG 14 which focuses on the conservation and sustainable use of marine resources, are also in line with this unique idea.

Energy is the lifeline for the whole of the service and industry sector in any country. Any imbalance in the energy sector is reflected on other sectors and the standard of living in the country. Energy problems are one of the most complex challenges facing governments. Especially in countries that rely on external energy sources. This situation is increased complexity by the presence of immediate changes in international relations and in fuel prices. Jordan is among the countries that depend on foreign energy sources and is located in the most volatile regions of the world in middle of the Middle East. Jordan is suffering from a permanent energy crisis that needs solutions which are compatible with many factors that may affect energy choices and decisions and alternatives available to get out of this crisis. Therefore, this study will attempt to focus on the Jordanian situation and identify the challenges and available choices. A comparison will be made of the available alternatives through Analytical Hierarchical Process (AHP). The results show that the priority of the energy solutions is to expand the mining of uranium and shale as well as to expand the construction of renewable power plants, as well as maintenance and modernization of existing plants and the establishment of new refineries.

Saudi Arabia is finally catching up with the rest of the developed world in terms of environmental awareness. In the past, while much of the rest of the world spent its time pondering issues such as global warming, water, air, and soil pollution, over-exploitation of resources, and a myriad of other environmental concerns, the Saudi people and government seemed to be primarily focused on expanding their capital in a globalized economy. However, in 2015, for the first time, this trend began to show legitimate change. This new emphasis on environmental concerns has caused some interest and uproar, specifically in the economic sector. The research, therefore, concentrated on the barriers, strategies, and opportunities that might impede or encourage Saudi Arabia in its quest to develop a greener and more sustainable economic infrastructure. After carefully considering the available literature, data, and reliable statistics, the report concluded that, while change will be difficult and, possibly slow, Saudi Arabia should expect to see greener projects and initiatives transpiring in their homeland over the course of the next several years.

As an ecological source of renewable energy, the available kinetic energy of rainfall is not trifling, especially in tropical countries at the equators. The research on the use of piezoelectric transducer to harvest raindrop kinetic energy is gaining more and more attention recently. This article reviews the state-of-the-art energy harvesting technology from the conversion of raindrop kinetic energy using piezoelectric transducers as well as its interface circuits for vibration-based energy harvesters. Performance of different types of piezoelectric harvesters in terms of power output, area power density and energy conversion efficiency are compared. Summaries of key problems and suggestions on the optimization of the performance of the piezoelectric harvesters are also provided for future works.
