Green Solutions To Solve Environmental Stress

Our world is facing a shortage of food, water and energy. Day in and day out we are in search of non-renewables which can cater to the huge global population needs. We need to run our business as well as meet the increasing demand. But that again leaves us with the odd question, if we are in the process of doing business as usual and wait till the world resources comes to an end? The time has come when we need to roughly estimate as to how much time we have till we end up using these non-renewables.

Environmental stress creates ecological deficits and leads the world towards finding alternatives and it becomes clear that these also generates fiscal deficits. Agriculture, Water, Energy, Food are the key to GDP of a country and less rainfall means loss in all these sectors. Hence Ecological and Economic deficits are shaping our present as well as our future. The threat to our future generations are not war, but shortage of water, food and energy.

Global warming has led to many new facts and let’s analyse these with a few examples. During the summer of 2010, record high temperatures hit many parts of Moscow and it is the same with increasing temperature in many countries including United Kingdom. As per meteorological office in the United Kingdom, June, 2018 was a warm and dry month for most and for some it was record-breaking, with many seeing their warmest and driest June on record. Throughout June high pressure dominated the UK weather, bringing more than our normal share of fine sunny days with high temperatures and very little rainfall. Provisional statistics show it is one of UK’s top five warmest Junes (in records dating back to 1910) for both maximum daytime and mean (24-hour average) temperatures. When looking at the mean temperatures it has been the warmest June on record for Northern Ireland and Wales and 4th warmest for Scotland and England.

In many countries there is a concept of carbon tax which is a fee imposed on burning of carbon-based fuels (coal, oil, gas). More to the point, a carbon tax is the core policy for reducing and eventually eliminating the use of fossil fuels whose combustion is destabilizing and destroying our climate. However, it is not the only way to reduce global warming and other related environmental disturbances. There are other ways also to reduce carbon foot print at the personal level by planting small plants in your surroundings, switching off to less electricity and using solar powered lamps for lighting at night, keeping some organic plantation for foods, taking more public transport instead of one’s own vehicles etc. This and many more can be done at the personal level but what about those initiatives which can be done in an Industrial level? Personally, I feel that Industries need to first switch on to solar power for inner lighting. If we can somehow, reduce the intake of electricity in our life by use of solar and wind energy, then one can do wonders. If we can just start with this one system of consumption of electric energy through this method, we can set examples.

Electricity and fresh water are the areas, Industries may focus, in order to reduce environmental stress. Global electricity demand witnessed a 3.1 per cent jump in 2017 with major contribution coming from China and India. The two nations together accounted for 70 per cent of the rise as per a report from International Energy Agency. As per Energy World, with a third of the world’s population currently residing in India and China, the two countries accounted for a total of 540 Terra Watt Hour (TWh) of electricity demand growth in 2017, out of the global increase of 780 TWh. This global rise in electricity was significantly higher than the overall increase in the energy demand.

However, the disturbing part is that there is not much decline of investment in the non-renewables and hence expansion of electricity through renewables to meet our increasing energy demand is not coming up.

As per the World Energy Investment 2018 report, it is stated that for the third consecutive year, global energy investment declined, to USD 1.8 trillion (United States dollars) in 2017  – a  fall  of  2 %  in  real  terms. The good news is that clean energy supply investment has grown fastest in the power sector. The share of clean  power  sources  (renewables  and  nuclear)  in  generation  investment  was  over  70%  in  2017,  up  from  less  than  50%  a  decade  ago,  though  this  stems  partly  from  lower  coal-fired power  investment. As more and more industries join hands for greater spending on electricity networks and battery storage, it is also contributing to increase interest and investment in the Solar and wind Energies. Investments in these sectors need to rise for green electric to meet the increasing demand.

Working hand in hand with ecology and environment is one of the great way to a clean and green world as well as meet the higher energy demand caused by increasing human population. If only we have more forests, fresh streams, great crops and green electricity, the future centuries will be far better to live.

DISASTER MANAGEMENT NEEDS AND GREEN TOWNS

Angel

Across the world, there is a rapid increase in urban living and an ever greater understanding of the consequences of Global Climate Change. Indian Town is experiencing warmer weather, hotter summers and delayed winters. Even, we can expect much greater changes in the decades ahead.

The population is increasing day by day and with no specific control on the increasing population explosion, there is a fierce struggle for land and space. There is also an increase in the intake of food and water. So, all these factors lead to an increase in demand graph and supply chart seems to go down. This is a worrying fact for a town, which needs to survive this trouble times.

Hence, we need to find some sustainable approach to keep a balance. The approach should be in areas concerning water, land, food and the air we breathe. All these are the basics of human survival. Let us take the example of water. It’s not the simple expansion of irrigation. It had an ecological and social dimension as well and was the key to rural transformation. Providing a limited but assured quantity of water to all urban households irrespective of their landholding is the key for water conservation. Now, to serve such dispersed need, the systems required had to be entirely different – technologically and socially. The population of the world tripled in the 20th century and now the use of renewable resources have grown six fold. Within the next fifty years the World population will increase by 40%-50%. Now this population growth coupled with industrialization and urbanization will result in an increasing demand of water and will have serious consequences in the environment. Already there is more waste water generated and dispersed today than at any other time in the history of our planet: more than one out of six people lack access to safe drinking water, namely 1.1 billion people, and more than two out of six lack adequate sanitation, namely 2.6 billion people

(Estimation for 2002, by the WHO/UNICEF JMP, 2004). One must know that these figures represent only people with very poor conditions. In reality, these figures should be much higher.

Less availability of water leads to water stress. Water stress results from an imbalance between water use and water resources. The water stress indicator in this map measures the proportion of water withdrawal with respect to total renewable resources. The depleting resource leads to many tensions over neighbors, communities, districts, states and countries. So, it is a real fact that there is a water crisis today. “But the crisis is not about having too little water to satisfy our needs. It is a crisis of managing water so badly that billions of people – and the environment – suffer badly.” World Water Vision Report

With this current state of affairs, correcting measures still can be taken to avoid the crisis to be worsening. There is an increasing awareness that our freshwater resources are limited and need to be protected both in terms of quantity and quality. This water challenge affects not only the water community, but also decision-makers and every human being. “Water is everybody’s business” was one the key messages of the 2nd World Water Forum. Indian Towns are no different.

Another challenging factor, which haunts an Indian town, is Green Cover.

As per the report of National Institute of Environmental Studies, Bangalore has a Green Cover of 8.60 per cent, National Capital Region (New Delhi): 8.49 per cent, Greater Mumbai: 6.20 per cent, Chennai: 7.50 percent. The most astonishing fact is that Kolkata has a very less Green cover of 0.95 per cent. The numbers indicate percentage of green cover as a proportion of the total area for major Indian towns. Needless to say, the list — prepared by the Delhi-based National Institute of Environment Studies.

(NIES), who had made it clear that Calcutta has the lowest green count among all the towns.

It’s stated that as per the established norms the green cover should be atleast 15 percent for mega-towns for a population of one – million. Lack of open space and greenery increases air pollution and triggers respiratory and other problems, besides raising temperature, affecting biodiversity and causing psychosomatic disorders among citizens. According to the report it also states that the Green Cover of the town has continuously been depleting from 1.3 per cent in 1997-98 to 0.95 per cent in 1999-2000, due to indiscriminate felling of trees due to various reasons.

Hence, it is very clear that most Indian Towns faces many environmental challenges. The Project recognizes that a variety of methods will be needed to tackle climate change and its consequences and that living roofs and walls can play a significant role in tackling the situation. The greening of a roof can support rare and interesting types of plant, which in turn can host or provide suitable habitat for a variety of rare and interesting invertebrates.

These would serve many purposes:
a) Help to reduce global warming and green house gas effect
b) Help to reduce urban heat island effect (UHIE)
c) Help to reduce energy and carbon-dioxide emissions
d) Help to enhance bio-diversity, reduce flood, earthquake, cyclone and other disaster risks, provide insulation and improve the appearance of the town.

Creation of Green Bus Shelters will not only increase the green cover. The mission would be to increase the green look of the town as well as educate the public about the many environmental benefits of green roofs, as well as improve urban air quality and provide attractive waiting spaces for public transit users. The Green Bus Shelters will serve the following purposes:

a) Filtering air pollution and particulates from vehicle exhaust
b) Managing storm water by slowing the runoff rate
c) Adding an extra layer of insulation to roofs
d) Providing wildlife habitat opportunities in a dense urban area.

The next concept is Rain water harvesting and creation of Rain Homes. This will together create a Sustainable Rain Neighbourhoods. A sustainable neighbourhood is a mixed used area with a feeling of community. It is a place where people want to live and work, now and in the future. Sustainable neighbourhoods meet the diverse needs of existing and future residents, are sensitive to their environment, and contribute to a high quality of life. They are safe and inclusive, well planned, built and run, and offer equality of opportunity and good services to all. (Bristol Accord, 6-7 December 2005)

Sustainable Rain Neighbourhoods will make the communities have access to round the clock usage of water, irrespective of the number of people through effective capturing, storing and usage of Rain water.

Wastes and its disposal is another problem which haunts a metropolitan town. Human is behind every developmental sector. The large scale production and improper disposal of waste has become a source of pollution and further accumulation of garbage has resulted in serious deterioration of quality of life and the ecological balance. An initiative need to be taken on the need of systemic waste management.

An example of Kolkata states that approximately more than 2920 ton/d of solid waste are generated in the Kolkata Municipal Corporation (KMC) area and the budget allocation for 2007–2008 was Rs. 1590 million (US$40 million). Major deficiencies were found in all elements of Solid Waste Management. Lack of suitable facilities (equipment and infrastructure) and underestimates of waste generation rates, inadequate management and technical skills, improper bin collection are responsible for poor collection and transportation of municipal solid wastes. The project tries to give focus in this grey area and encourages segregation of wastes in homes. Segregation of waste right is a solution to the problem and the project focuses on this initiative.

Waste can be segregated as
1. Biodegradable
Organic waste, e.g. kitchen waste, vegetables, fruits, flowers, leaves from the garden and paper
2. Non-biodegradable
Recyclable waste – plastic, paper, glass, metal etc
Toxic waste – old medicines, paints, chemicals, bulbs, spray cans, fertilizer and
pesticide containers, batteries, shoe polish.
Soiled – hospital waste such as cloth soiled with blood and other body fluids.

Toxic and soiled waste must be disposed of with utmost care.

For any project to be successful, there need to create lot of awareness campaigns. The purpose of the campaign would be to help everyone learn how to make the town a better place to live, in both small and big ways. The project will focus on creation of WORLD BANK Calendars, posters, hoardings along with the State/Local Government for conservation of energy and water, reducing noise levels and importance of increasing Green Cover in the town.

The project hence focuses on the following:
a) Water Conservation ways
b) Creation of Sustainable Rain Neighbourhoods by creation of ‘RAIN HOMES’ and Rain Water Harvesting Method
c) Reducing the impact of natural disaster risks
d) Creation of Green Bus Shelters
e) Creation of Green living roofs and walls
f) Segregation of Wastes Bins
g) Calendar, Poster, Hoarding on conservation of energy and water, reducing noise levels and importance of increasing Green Cover.
g) Tie- up with local FM channels.

CONCLUSION:

Across the world there is a rapid increase in urban living and an ever greater understanding of the consequences of global climate change. Indian Cites is experiencing warmer, wetter winters; hotter, drier summers and we can expect much greater changes in the decades ahead. As population increases, we are developing more sustainable approaches to development, using natural systems to shape and support growth. Excellent architecture and urban design is required if the Town has to adapt to the extremes of climate change. The concept would help to solve the existing environmental problem and make a Green Town with clean air – a role model for other mega towns that are contending with similar problems. The activities of the proposal will develop the technological concepts that make life in tomorrow’s mega towns easier, kinder and more pleasant to the environment.

DISASTER MANAGEMENT AND GREEN CITIES

Greener City
Green City

I thought of writing this small write-up since it has been going in my mind for last two years. I’m trying to express that thought through the following document.

Across the world, there is a rapid increase in urban living and an ever greater understanding of the consequences of Global Climate Change. Cities are experiencing warmer weather, hotter summers and delayed winters. Even, we can expect much greater changes in the decades ahead.

The population is increasing day by day and with no specific control on the increasing population explosion, there is a fierce struggle for land and space.

Indian Cities are no different.

Another challenging factor, which haunts an Indian city, is Green Cover.

As per the report of National Institute of Environmental Studies, Bangalore has a Green Cover of 8.60 per cent, National Capital Region (New Delhi): 8.49 per cent, Greater Mumbai: 6.20 per cent, Chennai: 7.50 percent. The most astonishing fact is that Kolkata has a very less Green cover of 0.95 per cent. The numbers indicate percentage of green cover as a proportion of the total area for major Indian cities.

Sustainable Rain Neighbourhoods will make the communities have access to round the clock usage of water, irrespective of the number of people through effective capturing, storing and usage of Rain water.

Wastes and its disposal is another problem which haunts a metropolitan city. Human is behind every developmental sector. The large-scale production and improper disposal of waste has become a source of pollution and further accumulation of garbage has resulted in serious deterioration of quality of life and the ecological balance.  An initiative need to be taken on the need of systemic waste management. We need to have good projects all around the globe to address these issues and plan its mitigation policies. It’s then we can move towards a Safer World for us as well as for the future generations.

For any project to be successful, there is a need to create lot of awareness campaigns. The purpose of the campaign would be to help everyone learn how to make the city a better place to live, in both small and big ways.

Hope through these write-up, International Agencies, Government and Non-Government organizations take up these projects so that we can see a Greener and a Safer World.

Thanks a lot for reading. Please put a comment if your time permits.
