Brownfield land is the lands that previously used for industrial or commercial purposes with known or suspected pollution including soil contamination due to hazardous waste. Luckily, landscape architects and urban planners found a innovative solution to clean the brownfild land become it to a community park. That means the cleaned up sites will be reused to protects public health and the environment by preventing sprawl, preserving green space and reinvigorating communities. The Atlanta BeltLine,  Atlanta, Georgia, United States The splashpad at Historic Fourth Ward Park. The Atlanta BeltLine is a prime example of “upcycling” underutilized urban space. Initially a hypothetical thesis project by a student at Georgia Tech in 1999, the project has become one of the largest urban redevelopment programs in the United States. It boasts a planned 520 hectares (1,300 acres) of new parkland—that’s more than the 340 hectares (840 acres) of New York City’s Central Park. Add the...

Rapid urbanization trends led to unsustainable environmental demand, thus city need a balance development between ecosystem and construction of urbanization for urban sustainability. While the traditional means of ecological reconstruction can not provide a solution for the human environment and ecological functions. Landscape ecology points out that Ecological reconstruction is a kind of intervention of ecological restoration. Ecological functions can be reinforced and created through the physical structure of the landscape. That means using the flexibility of the ecosystem, take human measures to help the damaged ecological environment gradually restored, or make the ecosystem to the direction of good circulation. Such as restoring the original ecosystem, protecting soil erosion, adjusting the microclimate, purifying the environment, and maintaining the ecological functions of biodiversity. At present, the urban ecological reconstruction mainly relies on the ecosystem self-organ...

The University of the District of Columbia (UDC) proposed a idea of creating sustainable urban food system aim to solve a city challenged with high levels of poverty, obesity, and population growth. From cultivation, preparation, and distribution to food waste management, this project will provides food security for city residents but does not compromise Earth's systems or the ability of our species to survive. UDC created a rooftop farm in the campus, which is the largest rooftop farm in the city to plant the vegetable and flowers. Beyond the campus, the Firebird Farm is working for the sustainable agri-experiments. Here UDC is experimenting with a wide selection of crops and techniques to sustainably provide food for a growing city. UDC is not just focused on growing crops on the campus and farm, they also build the “Urban Food Hub” include farms, hydroponics systems, and food preparation facilities in the city,   aim to providing new skills, jobs, and healthy sustainable fo...

Recently, an article about Uruguay's Energy Transition become a hot debate topic. The author stated that a renewable energy is possible further. According to the sector statistics shows, (figure 1) in 2014,  more than 90 percent of the country’s electricity generation came from clean energy sources in 2014, including from hydropower, biomass, and wind energy. However, Uruguay was a former energy importer in 2006,  34 percent of its electricity demand was supplied by neighboring countries such as Argentina. In 2015,  Uruguay  has shifted its role to become a net energy exporter,  10 percent of electricity generated locally was, instead, exported.  What is the benefits of energy transition? Obviously, p rioritizing renewable energy development enables Uruguay to turn its energy transition into environmental, security, and economic successes. As a result of renewable  energy,  emissions from domestic power generation will be just 17...

In the Bo01, The waste management system was created with the aim to develop a system that minimises the amount of waste, makes reuse and recycling possible and enables the use of waste and sewage as an energy source. Having waste separation units close to home is an important part of the planning of the area. The inhabitants usually have a separation room in their house or close by, making it easy for them to sort paper and packaging materials. Organic kitchen waste is ground at the residence and collected in underground vaults (Figure 1), from which it is pumped to an anaerobic digestion chamber. The biological treatment of this slurry by bacteria creates biogas (methane), which is drawn off and used to power public buses or used to generate heat and electricity. Figure 1. Food waste disposer the organic waste are grinded and disposed in separate pipes to a collector tank under ground. Similarly, the non-organic waste is deposited in the vacuum tubes located in the res...

Cities with overbuilt roadways have experienced unintended consequences, linked to radical drops in public transport, walking, and cycling. Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Therefore, public transport is crucial to the livability of any city because of its social, economic and environmental benefits. Environmental benefits Reduces pollution - Public transportation use in the United States reduces our nation's carbon emissions by 37 million metric tons annually. Saves energy - Public transportation use in the United States saves 4.2 billion gallons of gasoline annually. Social benefits Public transportation provides personal mobility and freedom for people from every walk of life. Public transportation provides access to job opportunitie...
