The cold heavier air during winters gets settled in Delhi and the air pollution starts choking in. In Delhi use of pet coke, furnace oil and even coal has been completely banned for industrial use. The Air Quality Index (AQI) is used by the government agencies to let the public know about the level of pollution at present along with the future forecasts. The Air Quality Index (AQI) also focusses upon health effects based upon the observations made within few hours or days after breathing polluted air.

  • Over population, Urbanisation, Developmental pressure on forests are acting as the human made catalysts causing desertification.
  • Other causes of Desertification include wind, drought and excessive rains.
  • As per the United Nations Statistics, 41 percent of Himachal Pradesh is under desertification.
  • During winters the willow saplings get eaten up by the yaks leaving the patches denuded again.
  • It is expected that almost 60 % of the world’s wheat-growing areas will face severe water scarcity by the end of the century unless climate change is mitigated.
  • Land requires a specific amount of moisture to grow wheat and paddy.
  • If Punjab keeps on sharing its water with other states the entire land area might become unproductive with the ground water level dropping every day.

Sustainable Development Goals

  • Sustainable Development Goals were adopted in 2015 as a global agenda with an aim to end poverty, protecting the planet, ensuring peace and prosperity to all the people.
  • The UNCTAD (The United Nations Conference on Trade and Development) in its report published on September 26,2019 proposed that the financial mechanism should help in achieving the SDGs by creating long-sought global environmental protection fund. The poor and developing countries needs to be supported without strict policies and conditional ties.
  • The SDGs should be achieved for low and lower-middle-income developing countries till 2030.
  • There is a need to develop energy sources along with the use of power generating freshwater meeting the energy needs of the poor and developing countries. For example Djibouti or Eritrea-the poorest of the poor sub-Saharan countries-have excellent geothermal resources.
