Greening
Greening is the process of transforming living environments, and also artifacts such as a space, a lifestyle (sociology), lifestyle or a brand image, into a more environmentally friendly version (i.e. 'greening your home' or 'greening your office'). The act of greening generally involves incorporating more environmentally friendly systems into one's environment, such as the home, work place, and general lifestyle. Greening is also a general term for the appropriate selection and planting of plants on, in, or next to buildings and in public parks. The goal of greening is usually a combination of environmental benefits and improving the visual design of surfaces, for example, a green wall or green roof, as well as the creation of green spaces. This usually requires technical measures such as earthworks or supporting climbing plants. Furthermore, permanent care and irrigation is usually necessary to maintain the greened environment. In some areas there are normative requirements f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert Greening
Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life. The term "desert greening" is intended to apply to both cold and hot Desert climate, arid and Semi-arid climate, semi-arid deserts . It does not apply to ice capped or permafrost regions. It pertains to roughly 32 million square kilometres of land. Deserts span all seven continents of the Earth and make up nearly a fifth of the Earth's landmass, areas that recently have been increasing in size. As some of the deserts expand and global temperatures increase, the different methods of desert greening may provide a possible response. Planting suitable flora in deserts has a range of environmental benefits from carbon sequestration to providing habitat for Xerocole, desert fauna to generating employment opportunities to creation of habi ...

Green Roof
A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. Container gardens on roofs, where plants are maintained in pots, are not generally considered to be true green roofs, although this is debated. Rooftop ponds are another form of green roofs which are used to treat greywater. Vegetation, soil, drainage layer, roof barrier and irrigation system constitute the green roof. Green roofs serve several purposes for a building, such as absorbing rainwater, providing insulation, creating a habitat for wildlife, and decreasing stress of the people around the roof by providing a more aesthetically pleasing landscape, and helping to lower urban air temperatures and mitigate the heat island effect. Green roofs are suitable for retrofit or redevelopment projects as well as new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Green Wall (China)
The Great Green Wall, officially known as the Three-North Shelter Forest Program ( zh, s=三北防护林, t=三北防護林, p=Sānběi Fánghùlín), is a series of human-planted windbreaking forest strips (shelterbelts) in China, designed to hold back the desertification, expansion of the Gobi Desert and provide timber to the local population. The program started in 1978 and is planned to complete around 2050, at which point it will be expected to have created a vast green barrier spanning approximately long and up to wide in certain regions, and will encompass around 88 million acres of forests. The project's name indicates that it is to be carried out in all three northern regions: the North China, North, the Northeast China, Northeast, and the Northwest China, Northwest. This project has historical precedents dating back to before the Common Era. However, in premodern periods, government-sponsored afforestation projects along the historical frontier regions were mostly fo ...

Urban Green Space
In land-use planning, urban green spaces are open-space areas reserved for parks and other "green spaces." These include plant life, water features also known as blue spaces and other kinds of natural environments. Most urban open spaces are green spaces, though some may consist of other types of open areas. The landscape of urban open spaces can range from playing fields and other highly maintained environments to more natural landscapes that appear less managed. Urban green spaces may also include areas that are not publicly accessible, such as privately owned higher education campuses, school sports fields, allotments, neighborhood or community parks and gardens, and corporate campuses. Areas outside city boundaries, such as state and national parks or rural open spaces, are not generally considered urban open spaces. Boulevards, piazzas, plazas, and urban squares are not consistently classified as urban open spaces in land-use planning. Urban greening policie ...

Green Wall
A green wall is a vertical built structure intentionally covered by vegetation. Green walls include a vertically applied growth medium such as soil, substitute substrate, or hydroculture felt; as well as an integrated hydration and fertigation delivery system. They are also referred to as living walls or vertical gardens, and widely associated with the delivery of many beneficial ecosystem services. Green walls differ from the more established vertical greening typology of 'green facades' as they have the growth medium supported on the vertical face of the host wall (as described below), while green facades have the growth medium only at the base (either in a container or as a ground bed). Green facades typically support climbing plants that climb up the vertical face of the host wall, while green walls can accommodate a variety of plant species. Green walls may be implanted indoors or outdoors; as freestanding installations or attached to existing host walls; and applied in a v ...

Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Environmental Hazard
Environmental hazards are hazards that affect biomes or ecosystems. Well known examples include oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, and Carbon dioxide in Earth's atmosphere, build-up of atmospheric carbon dioxide. Types Environmental hazards can be categorized in many different ways. Broadly, environmental hazards are categorized as chemical, physical, biological, or psychological, or a combination of these. Chemical hazards are substances that can cause harm or damage to humans, animals, or the environment. They can be in the form of solids, liquids, gases, mists, dusts, fumes, and vapors. Exposure can occur through inhalation, skin absorption, ingestion, or direct contact. Chemical hazards include substances such as pesticides, solvents, acids, bases, reactive metals, and poisonous gases. Exposure to these substances can result in health effects such as skin irritation, respiratory problems, organ damage, neurological effect ...

Recycled
Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling). Recycling is a key component of modern waste reduction and represents the third step in the "Reduce, Reuse, and Recycle" waste hierarchy, contributing to environmental sustainability and resource conservation. It promotes environmental sustainability by removing raw material input and redirecting waste output in the economic system. There are some ISO standards related to recycling, su ...

Packaging And Labelling
Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and for personal use. ''Package labeling'' (American English) or ''labelling'' (British English) is any written, electronic, or graphic communication on the package or on a separate but associated label. Many countries or regions have regulations governing the content of package labels. Merchandising, branding, and persuasive graphics are not covered in this article. History of packaging Ancient era The first packages used the natural materials available at the time: baskets of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beersheba
Beersheba ( / ; ), officially Be'er-Sheva, is the largest city in the Negev desert of southern Israel. Often referred to as the "Capital of the Negev", it is the centre of the fourth-most populous metropolitan area in Israel, the eighth-most populous Israeli city with a population of , and the second-largest city in area (after Jerusalem), with a total area of 117,500 dunams (45 mi2 / 117.5 km2). Human habitation near present-day Beersheba dates back to the fourth millennium BC. In the Bible, Beersheba marks the southern boundary of ancient Israel, as mentioned in the phrase " From Dan to Beersheba." Initially assigned to the Tribe of Judah, Beersheba was later reassigned to Simeon. During the monarchic era, it functioned as a royal city but eventually faced destruction at the hands of the Assyrians. The Biblical site of Beersheba is Tel Be'er Sheva, lying some 2.5 miles (4km) distant from the modern city, which was established at the start of the 20th century by ...

Efficient Energy Use
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, building insulation, insulating a building allows it to use less heating and cooling energy while still maintaining a Thermal comfort, comfortable temperature. Another method made by Lev Levich is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in Green building, buildings, industrial processes and Energy efficiency in transport, transportation could reduce the world's energy needs in 2050 by one third. There are two main motivations to improve energy efficiency. Firstly, one motivation is to achieve Operating cost, cost savings during the operation of the appliance or process. However, installing an energy-efficient technology comes with an upfront cost, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reuse
Reuse is the action or practice of using an item, whether for its original purpose (conventional reuse) or to fulfill a different function (creative reuse or repurposing). It should be distinguished from recycling, which is the breaking down of used items to make raw materials for the manufacture of new products. Reuse—by taking, but not reprocessing, previously used items—helps save time, money, energy and resources. In broader economic terms, it can make quality products available to people and organizations with limited means, while generating jobs and business activity that contribute to the economy. Examples Reuse centers and virtual exchange Reuse centers (also known as a "swap shop" or a "take-it-or-leave-it") facilitate the transaction and redistribution of unwanted, yet perfectly usable, materials and equipment from one entity to another. The entities that benefit from either side of this service (as donors, sellers, recipients, or buyers) can be businesses, nonprof ...
