Green Cities are solutions to Climate Change crisis



Green Cities are solutions to Climate Change crisis
Earth Day 2014 will focus on Green Cities, mobilizing a millions of people to create a sustainable, healthy environment by greening communities worldwide. Today, more than half of the world’s population lives in cities.
The India’s population is expected to reach about 1.5 billion by 2030 looking at the current trends of population index.  This high population growth to concentrate in cities with higher economic output enables the migration from rural areas causing a tremendous impact on the existing urban infrastructure. It is predicted that India will have six megacities having a population of more than ten million each and 68 cities will each have more than one million inhabitants, by 2030.
The rapid growth of cities have challenged the urban infrastructure planners and designers how to resolve the burgeoning  issues like., inadequacy of water supply, overloading of urban drainage systems, insufficient power supply, unreliable public transportation systems and limited access to adequate medical treatment. To address these issues, a reliable and efficient urban infrastructure complimenting the population growth needs to be updated accordingly. As the urban population grows and the effects of climate change worsen, our cities have to evolve. However, this being highly complex requires creating a knowledgeable manpower to help the cities to become more sustainable and reduce their carbon footprint.  Wherein, the cities can accelerate their transition to a cleaner, healthier, and more economically viable future through improvements in efficiency, investments in renewable technology, and regulation reform in three key elements – buildings, energy, and transportation.
Green Cities the theme of world Earth day 2014; to emphasis on the study of complex behaviour of urban agglomeration, to impart the requisite skills for planning, designing and executing the systems responsive for reliable, effective and efficient urban infrastructures, which can reduce the Green House Gases (GHG) considerably, few to name are., Firstly; Energy, switching to sustainable and renewable energy sources. Secondly, Green Buildings: implementing Green Building Code (GBC) in the design and construction of buildings reduces one third of all global greenhouse gas emissions. Thirdly, Transportation: Transportation is the fastest growing source of greenhouse gas emissions worldwide, three quarters of which comes directly from road vehicles. To reduce these emissions and the resulting smog, by implementing car pooling to work, restraining private vehicle entry to busy commercial areas, emphasis be on  public transportation options, invest in alternative transportation, like mono rail, metro etc, and have dedicated lanes for Cycling and Walking.
It’s time for us to invest in effective, efficient, environment friendly mode of transportation, Green buildings, and use of Green Energy, like  renewable energy, to rebuild our cities and towns, and begin to solve the climate crisis. More than that, sustainability implies responsible and proactive decision-making and innovation that minimises negative impact and maintains balance between ecological resilience, economic prosperity, political justice and cultural vibrancy to ensure a desirable cities for all species now and in the future.

Lastly I would like to conclude with an appeal of UN Secretary-General Ban Ki-moon “I appeal to all people everywhere to raise their voices. Speak out on behalf of this planet, our only home. Let us care for Mother Earth so she can continue to care for us as she has done for millennia."
