ESCAP- United Nations Economic and Social Commission for Asia and the Pacific (ESCAP)

India has been the founding member of ESCAP.
UNESCAP is the regional development arm of the United Nations in Asia and the Pacific, with a membership of 62 Governments, including 58 from the region.
Established in 1947 with its headquarters in Bangkok, Thailand.
UNESCAP serves as the highest intergovernmental regional platform to promote cooperation among member States for creating a more interconnected region working to achieve inclusive and sustainable economic and social development.
It carries out work in the areas of macroeconomic policy, poverty reduction and financing for development; trade and investment; transport; environment and sustainable development; information and communications technology and disaster risk reduction; social development; statistics, sub-regional activities for development; and energy.
UNESCAP also focuses on sub-regional activities to provide in-depth technical assistance to address specific key priorities, including poverty reduction and sustainable development, in the respective sub-regions.

What is the one ‘One Nation, One Ration Card’ system?

Under the National Food Security Act, 2013, about 81 crore persons are entitled to buy subsidized foodgrain — rice at Rs 3/kg, wheat at Rs 2/kg, and coarse grains at Re 1/kg — from their designated Fair Price Shops (FPS) of the Targeted Public Distribution System (TPDS).
Currently, about 23 crore ration cards have been issued to nearly 80 crore beneficiaries of NFSA in all states and UTs.
In the present system, a ration cardholder can buy foodgrains only from an FPS that has been assigned to her in the locality in which she lives.
However, this will change once the ONORC system becomes operational nationally.

How would that work?

Under the ONORC system, the beneficiary will be able to buy subsidised foodgrains from any FPS across the country.
The new system, based on a technological solution, will identify a beneficiary through biometric authentication on electronic Point of Sale (ePoS) devices installed at the FPSs.
This would enable that person to purchase the number of foodgrains to which she is entitled under the NFSA.

Explanation:

The West Bank is located to the west of the Jordan River.
It is a patch of land about one and a half times the size of Goa, was captured by Jordan after the 1948 Arab-Israeli War.
Israel snatched it back during the Six-Day War of 1967 and has occupied it ever since.
It is a landlocked territory, bordered by Jordan to the east and Israel to the south, west and  north.
Following the Oslo Accords between the Israeli government and the Palestine Liberation Organization (PLO) during the 1990s, part of the West Bank came under the control of the Palestinian Authority.
With varying levels of autonomy, the Palestinian Authority controls close to 40 per cent of West Bank today, while the rest is controlled by Israel.

Global Forest Resources Assessment
The Global Forest Resources Assessment (FRA) reports on the status and trends of the world’s forest resources.
It is led by the Forestry Department of the Food and Agriculture Organization of the United Nations.
The FRA reports the extent of the world’s forest area as well as other variables, including land tenure and access rights, sustainable forest management (SFM), legal and institutional frameworks for forest conservation, and sustainable use.

Explanation:

General relativity’s light-bending effect proved valuable for much more than affirming Einstein’s theory. By bending light, masses act like a lens; such “gravitational lensing” alters the apparent position of a distant object, creating multiple images of it, or (if the images overlap) appearing to brighten it.
Einstein succeeded in showing that matter and spacetime mutually interact to mimic Newton’s naïve idea that masses attract each other. Gravity, said Einstein, actually moved matter along the curving pathways embodied in spacetime — paths imprinted by mass and energythemselves.
