27th BASIC Ministerial Meeting on Climate Change held in New Delhi

27th BASIC Ministerial Meeting on Climate Change held in New Delhi has urged advanced countries to enhance their support to developing nations in effectively implementing Paris Agreement to combat climate change. BASIC countries comprise Brazil, South Africa, India and China. This comes ahead of UN Conference of Parties (COP) scheduled to be held in December 2018 in Katowice, Poland.

Outcomes of Meeting

Participating BASIC countries reaffirmed that Paris Agreement is significant step to advance global action against climate change, recognising needs and special circumstances of  developing countries.

They also reaffirmed member countries’ commitment to implement UN Framework Convention on Climate Change (UNFCC) its Kyoto Protocol and Paris Agreement. It resolved to promote low carbon transition to safeguard future of mankind.

As a group they will continue to push for developed countries on their earlier commitment to providing $100 billion annually from 2020. They also urged developed countries to take urgent actions to close pre-2020 implementation gaps by 2023 which they said can be useful input for first Global Stocktake (GST). Brazil will host next BASIC meeting in 2019.

Global Stocktake (GST)

GST refers to proposed five-yearly-review of the impact of climate change action undertaken by countries. Under the Paris Agreement, each country has to present a climate action plan every five years. Under the Paris Agreement, the first global stocktake will happen in 2023. It will help world to determine whether it needs to do moreand how much more. India is demanded for 10-year period for GST, while EU and some others demanded five-year cycle. India argues that five years is too short a time to assess whether the actions were having the desired impacts.


BASIC countries are bloc (geopolitical alliance) of four large newly industrialized countries – Brazil, South Africa, India and China. It was formed by agreement in November 2009. They were committed to act jointly at Copenhagen climate summit 2009, including possible united walk-out if their common minimum position was not met by developed nations during climate talks. It is working to define common position on emission reductions and climate aid money and try to convince other countries to sign up to Copenhagen Accord.

IIT-Hyderabad researchers develop smartphone-based system to detect adulteration in milk

Researchers from Indian Institute of Technology (IIT) Hyderabad are working to develop smartphone-based sensor to detect adulteration in milk. They have developed detector system which can measure level of acidity in milk using indicator paper. They have also developed algorithms that can be incorporated in smartphone to accurately detect change in acidity. The sensor-chip based method measures pH, which is indicator of the acidity and colour of paper indicates different pH levels.

Key Facts

In this adulteration detection system, researchers have used process called ‘electrospinning’ to produce paper-like material made of nanosized fibres of nylon, loaded with combination of three dyes. The paper is halochromic i.e. it changes color in response to changes in acidity.

Researchers developed prototype smart phone-based algorithm in which colours of sensor strips after dipping in milk are captured using camera of phone and data is transformed into pH (acidity) ranges.

They have used three machine-learning algorithms and compared their detection efficiencies in classifying colour of indicator strips. On testing this system with milk spiked with various combinations of contaminants, it found near-perfect classification with accuracy of 99.71%.


According to recent report by Animal Welfare Board (statutory advisory body under Ministry of Environment, Forest and Climate Change) shows that 68.7 % of milk and milk by-products in the country are adulterated with products such as detergent, glucose, urea, caustic soda, white paint and oil. Chemicals such as formalin, boric acid, hydrogen peroxide and antibiotics are also added to milk to increase shelf life. Regular consumption of adulterated milk can cause heart diseases (such as high or low blood pressure, cardiac arrhythmia, premature ventricular contraction etc,), kidney diseases, poor eyesight, loss of memory, cancer, skin diseases, eye diseases, gastrointestinal diseases such as ulcers
