Sustainable cities are eco-friendly urban settlements established with their natural resources. There are practical ways through which such cities are developed. Let’s examine some of these methods. Exploration of Agricultural Systems There’s need to explore various agricultural systems within the city. The agricultural plots within the suburbs should be developed through large scale farming, for the production of enough food to sustain the individuals in the city. This reduces over-dependence on food imports. Renewal of Energy Sources A sustainable city also known as green city or smart city can be developed through the renewal of its local energy sources, such as solar panels, wind turbines, bio-gas from sewage and other likely sources. Such energy sources can be well developed to sustain all the energy requirements of the city. Creation of Natural Ventilation Systems Sustainable development of a city is possible when artificial air conditioning systems are replaced with natural ventilation systems. Such natural ventilation is possible through the planting of trees, building of green houses and other means. Public Transport Improvement To create a fully sustainable city, it is essential to improve the public transport system. The construction of double lane expressways with pedestrian lanes and bridges should be a key priority. This helps to reduce car emission, car wreckages, and automobile accidents. Proper Waste and Water Management Wastewater management is very important in the creation of a sustainable city. Measures should be taken to ensure the free flow of water ways, throughout the city. Water bore-holes should be dug to provide clean and drinkable water to the city’s residents. Effective waste management must be pursued with vigor and interest. There should be a location set apart for the dumping of waste. Such waste products can also be converted to energy producing elements through appropriate means. Proper Building Plans Sustainable cities require proper building plans to make them more hospitable. Public transport systems are a more viable option when optimal building density is in place. Industries and market places should be properly separated from residential areas in order to improve healthy living. Indeed, there are lots of other avenues that can be pursued in order to assist the development of sustainable cities. Some of these include zero emission transport systems, zero-energy building plans, green roofs integration, efficient urban drainage systems, energy conservation system and others. When all these steps are employed, sustainable cities are sure to thrive.
