Swale Design for Watershed Management + (According to United Nations Environment Pr … According to United Nations Environment Programme (UNEP), the volume of freshwater resources is about 2.5 per cent of the total volume of water on earth. Of this freshwater, only 30 per cent is stored in the form of groundwater which accounts for 97 per cent of all freshwater potentially available for human consumption. However, much of the groundwater we rely on is slowly being depleted from underground aquifers through pumping. The overpumping of groundwater is causing water tables to fall across large areas of northern China, India, Pakistan, Iran, the Middle East, Mexico, and the western United States. Scientists have recently estimated in India that groundwater is being depleted across the country's north at a rate of 54 billion cubic meters per year. This is putting the nation's food supply and the region's 114 million people—are increasingly at risk.4 million people—are increasingly at risk.)

In other words: New Urbanism focuses on human-scaled urban design. The principles, articulated in the Charter of the New Urbanism, were developed to offer alternatives to the sprawling, single-use, low-density patterns typical of post-WWII development, which have been shown to inflict negative economic, health, and environmental impacts on communities.''nd environmental impacts on communities.'')

In 1951, afterWorld War II, the area of plantation was only 49 700 km. Considering the economicimportance of the forestry production, Japan set up the forest policies to increase theplantation. Because of this effort, the total area of plantation becomes 103 300 km2.The major reason for sustaining this level of man-made forests is that most of theseforests are less than 35 years old, and have not reached the standard harvesting age.Meanwhile, the forestry and wood industries in Japan faced difficult conditions; i.e.,stagnation of timber prices, difficulties in maintaining labor force and competitionwith imported timber and wooden products. with imported timber and wooden products.)

Evaluation of lab performance of stamp sand and acrylonitrile styrene acrylate waste composites without asphalt as road surface materials + (Acrylonitrile styrene acrylate (ASA) plast … Acrylonitrile styrene acrylate (ASA) plastic and stamp sand are both waste materials that impose a significant burden on the environment. This study investigates the potential of using stamp sand and ASA plastic composite as the pavement structure. It should be noted that this new material does not use the asphalt binder. A series of lab tests usually used for asphalt pavement materials were employed for the stamp sand and ASA plastic composite material. The high-temperature properties were analyzed by the Hamburg wheel tracking device (HWTD), while the low-temperature performance was measured by the disc-shaped compact tension (DCT) test. The tensile strength ratio (TSR) was used to determine the moisture susceptibility and the dynamic modulus was used to assess the deformation characterize under various loads and frequencies, the coefficient of permeability was estimated by the water permeability test, and the mass loss of aggregate was estimated by the Cantabro loss test. The dynamic modulus results showed that the ASA mixtures have improved high-temperature deformation resistance as compared to the asphalt mixtures. The ASA mixture with 40% sand showed higher stiffness than the ASA mixture with 30% sand. The ASA mixtures have excellent rutting resistance and moisture damage resistance. The fracture energy of the asphalt mixture is 42–77% higher than the ASA mixture. The tensile strength ratio of the ASA and asphalt mixture are all larger than 0.8 and therefore satisfy the Superpave specification. The average coefficient of permeability of the ASA mixture is 6–10 times higher than the asphalt mixture in the same air void level. The average aggregate loss percent of the ASA mixtures is 9.2–10.8 times higher than asphalt mixtures. In summary, the implementation of stamp sand and ASA plastic mixtures may be a successful solution to mitigate the environmentally harmful effects of waste plastic and stamp sand, as well as assist in offsetting the cost and negative effects of the asphalt mixtures typically used for road surfaces.mixtures typically used for road surfaces.)

Adaptive reuse + (Adaptive reuse is conventionally defined a … Adaptive reuse is conventionally defined as "the process of adapting old structures for new purposes." This process has a history that stretches back to antiquity and is so universal that we often fail to recognise it. <blockquote>To prolong the period from cradle-to-grave for a building by retaining all or most of the structural system and as much as possible of other elements, such as cladding, glass, and interior partitions. Reuse, readaptation, reappropriation of existing or built structures has remote historical precedents. In antiquity, durable, sturdy structures of stone and masonry outlived empires and often changed program many times. In modernity, the desire to preserve historical buildings and neighborhoods emerged in many Western countries out of various romanticist, nationalistic, and historicist streams. Today, the imperative to extend the life cycle of a structure is related to various sustainability goals: sprawl minimization, preservation of virgin materials, and energy conservation. Also, many Western cities are changing dramatically as industrial operations more often than not move to the South and the East leaving massive, sturdy buildings vacant. Institutional nature is also changing with many old hospitals, sanatoriums, military buildings, and even office blocks becoming redundant.

Open-source, self-replicating 3-D printer factory for small-business manufacturing + (Additive manufacturing with 3-D printers m … Additive manufacturing with 3-D printers may be a key technology enabler for entrepreneurs seeking to use disruptive innovations such as business models utilizing distributed manufacturing. Unlike centralized manufacturing, distributed manufacturing makes the parts and products (the prints) at (or closer to) the source of the demand, cutting out much of the traditional supply chain. Although many expect 3-D printing to take off at the household level and previous work has shown significant returns for those choosing to do so, there are still significant barriers to entry for typical consumers. Our analysis demonstrates that for an individual to make an abnormally high return on their investments in 3-D printers, they must serve others to achieve high utilization rates. The impetus to do so is created by a service that can undercut traditionally manufactured products due to affordability and customizability. Low-cost, open-source 3-D printers are now priced within range of individual entrepreneurs who can take advantage of the long tail of consumers with highly varied interests. The margin advantage, net present value, and return on investment (ROI) analysis provided herein could form the basis of thousands of new small-business ventures in the coming years.all-business ventures in the coming years.)

Quantifying Alternative Food Potential of Agricultural Residue in Rural Communities of Sub-Saharan Africa + (African countries have been severely affec … African countries have been severely affected by food insecurity such that 54% of the population (73 million people) are acutely food insecure, in crisis or worse. Recent work has found technical potential for feeding humanity during global catastrophes using leaves as stop-gap alternative foods. To determine the potential for adopting agricultural residue (especially crop leaves) as food in food-insecure areas, this study provides a new methodology to quantify the calories available from agricultural residue as alternative foods at the community scale. A case study is performed on thirteen communities in Nigeria to compare national level values to those available in rural communities. Two residue utilization cases were considered, including a pessimistic and an optimistic case for human-edible calories gained. Here, we show that between 3.0 and 13.8 million Gcal are available in Nigeria per year from harvesting agricultural residue as alternative food. This is enough to feed between 3.9 and 18.1 million people per year, covering from 10 to 48% of Nigeria’s current estimated total food deficit.ia’s current estimated total food deficit.)
