Green Infrastructure: The Key to a Sustainable Society

BENEFITS OF GREEN INFRASTRUCTURE

Green infrastructure is a type of approach to water management that reinstates the natural water cycle. It is a low-cost, resiliency-based solution to dealing with wet weather problems that have numerous community benefits. It basically means growing trees and reinstalling wetlands, instead of building an expensive water treatment plant. It means picking water efficiency over constructing a whole new dam.

Green Infrastructure integrates both our natural environment and different engineered systems to provide safe water and conserves the values and functions of our ecosystem. Green Infrastructure solutions can be applied at various scales, from a domestic level to a broader landscape level. At the smaller level, green infrastructure applications include rain gardens, permeable pavements, and rainwater harvesting mechanisms.

At the biggest scale, the protection of natural resources like forests and wetlands are important components of green infrastructure. Investing in green infrastructure boosts the economy, improves community health and safety, and provides opportunities for recreation, wildlife, etc. It provides a plethora of benefits to both humans and animals.

WHY SHOULD WE CHOOSE GREEN INFRASTRUCTURE?

Nature always works best: Rivers, streams, wetlands, floodplains, and forests provide a variety of crucial services such as clean water and flood protection, and they should be considered essential and effective components of our water infrastructure.

We need to save money: Spending money in the right way includes investing in multi-purpose solutions that reduce costs and provide us with more benefits. For instance, the City of Indianapolis has recently revealed that by reducing stormwater flows into their combined sewer system with wetlands, trees, and downspout disconnection, the City will be able to reduce the diameter of the planned new sewer pipe from 33' to 26', saving over $300 million.

Enhancement of community safety and enjoyment is required: Traditional infrastructure isn’t normally designed to deal with the increased floods and droughts that are a consequence of climate change. So, a modern approach is required to take care of public health, safety, and quality of life. Green Solutions are capable of giving communities the security and flexibility they need. Napa, a city in California chose to restore the natural course and wetlands of the Napa River. Rather than lining the river with concrete. In addition to protecting 2,700 homes and preventing $26 million in flood damage each year, the work has resulted in the creation of new parks and open spaces.

Different Benefits of Green Infrastructure:

Environmental:

Green streetscapes amplify urban biodiversity and provide a habit for various species of insects and birds. The native vegetation is suited to the rainfall of their local area. The enhancement of biodiversity in cities is capable of increasing awareness about the environment among urban residents.

It also helps in improving the quality of stormwater by reducing the load of harmful minerals, sediments, and other unwanted substances that are carried by runoff from impermeable substances.

The risk of erosion of the soil bed is reduced by retaining runoff in landscaped areas and decreasing the rate of flow from the catchment region. Slower flow rates also alleviate stress on downstream streams.

It helps in natural hydrology. In places suitable for local soil, rain gardens are used to treat stormwater before it obstructs the ground. It directs stormwater to irrigate a plantation. This reduces the need for manual watering and also increases soil moisture.

Social:

Green infrastructure helps in amenity and landscape design. Landscape design contributes to a city’s overall character and identity. Planting enhances the built environment by softening the impression of hard surfaces and creating a visual barrier.

Urban Cooling is another social benefit. Green infrastructure provides a sizeable decrease in urban temperatures. Tall trees with good soil moisture help reduce local temperatures by shading and transpiration. Trees are capable of reducing air temperatures in trailers and green areas by as much as 8 degrees Celsius. They also help in preventing the loss of lives during big heat waves.

Vegetation plays a major role in improving air quality. Trees absorb harmful greenhouse gases like nitrous oxide, nitrogen dioxide, carbon dioxide, sulphur dioxide, hydrogen sulfide, etc. from the atmosphere. The trees which are most effective in trapping pollutants and dust particles are the ones whose leaves have a large surface area and a high rate of transpiration.

Green Cover also influences various outdoor activities like walking, jogging, cycling, etc.

Economical:

Green Infrastructure aids in cutting energy demands. It reduces local temperatures and shading building surfaces. It also decreases the cooling needs of buildings, which helps in cutting energy needs.

It is beneficial for jobs and the economy. Green Solutions create good jobs in many sectors. These include design, engineering, and landscaping. It also helps many supply chains and important jobs which are connected with the manufacture of materials that include roof membranes and rainwater harvesting systems

It increases the lifespan of infrastructure. Grey infrastructure, such as catch basins and drainage pipes, is supplemented by green infrastructure, which extends the life of grey infrastructure.

The cost of mitigating erosion in waterways and the impact on drainage systems can be enormous. Green infrastructure in city streets slows runoff, reducing pressure on drainage systems and lowering maintenance costs.

It improves property values and marketability. Green infrastructure and trees on the side of streets augment aesthetic qualities and provide a significant neighborhood amenity. The properties located on streets lined with trees are usually valued as much to thirty percent more than those on streets without trees.
