Singapore Convention
It is aimed to provide a more effective way of enforcing mediated settlements of corporate disputes involving businesses in India and other countries that are signatories to the Convention.
Also known as the UN Convention on International Settlement Agreements Resulting from Mediation, this is also the first UN treaty to be named after Singapore.
With the Convention in force, businesses seeking enforcement of a mediated settlement agreement across borders can do so by applying directly to the courts of countries that have signed and ratified the treaty.
The harmonized and simplified enforcement framework under the Convention translates to savings in time and legal costs.
The Convention ensures that a settlement reached by parties becomes binding and enforceable in accordance with a simplified and streamlined procedure.

It is also a parliamentary device primarily meant for exercising legislative control over executive actions.

Right to question the executive: Historical background
The right to question the executive has been exercised by members of the House from the colonial period.
The first Legislative Council in British India under the Charter Act, 1853, allowed members the power to ask questions to the executive.
The Indian Council Act of 1861 allowed members to elicit information by means of questions.
However, it was the Indian Council Act, 1892, which formulated the rules for asking questions including short notice questions.
The Indian Council Act, 1909, which incorporated provisions for asking supplementary questions by members.
The Montague-Chelmsford reforms brought forth a significant change in 1919 by incorporating a rule that the first hour of every meeting was earmarked for questions.
Parliament has continued this tradition.
Since 1921, the question on which a member desired to have an oral answer, was distinguished by him with an asterisk, a star.

Severity of the nourishment problem in India
There were 189.2 million undernourished people (28 per cent of the world) in India in 2017-19, as per the combined report of FAO, IFAD, UNICEF, WFP and WHO (FAO, et.al. 2020) on “The state of Food Security and Nutrition in the World”.
India accounts for 28 per cent (40.3 million) of the world’s stunted children (low height-for-age) under five years of age, and 43 per cent (20.1 million) of the world’s wasted children (low weight-for-height) in 2019.
In India, the problem has been more severe amongst children below the age of five years.
As per the National Family Health Survey (NFHS, 2015-16), the proportion of underweight and stunted children was as high as 35.8 per cent and 38.4 per cent respectively.
In several districts of Bihar, Jharkhand, Uttar Pradesh, Madhya Pradesh, Rajasthan and even Gujarat, the proportion of underweight children was more than 40 per cent.
Aims of the National Nutrition Mission (NNM)
Ending all forms of malnutrition by 2030 is also the target of Sustainable Development Goal (SDG-2) of Zero Hunger.
Towards this end, NNM aims to reduce stunting, underweight and low birth weight each by 2 per cent per annum.
It aims to reduce anaemia among children, adolescent girls and women, each by 3 per cent per annum by 2022.
However, the Global Burden of Disease Study 1990–2017 has estimated that if the current trend continues, India cannot achieve these targets under NNM by 2022.
