NABH (Nextgen Airports for Bharat) Nirman initiative

  • Minister for Civil Aviation stated that the government is committed to the building of airport capacity as part of NABH (NextGen Airports for BHarat) Nirman initiative.
  • The three key aspects of NABH Nirman are
  1. Fair and equitable land acquisition
  2. Long-term master plan for airport and regional development and
  3. Balanced economics for all stakeholders.
  • The air traffic of the country is increasing, both at domestic and international level.
  • India airlines flew highest-ever domestic passengers by flying about 117 passengers during 2017.

UN report for social inclusion

  • The UN Economic and Social Survey of Asia and the Pacific 2018 was launched recently.
  • It urged countries to take advantage of high growth rate and share the benefits with the national society.
  • The report on the Asia-Pacific region has also urged the regional powers to invest in inclusive and sustainable growth.
  • The report described South and Southwest Asia as the fastest growing sub-region of the Asia-Pacific region.
  • It also highlights the need to increase the social spending by the government.
  • It is released by the UNESCAP (Economic and social commission for Asia-Pacific).

AI for Accessibility

  • Microsoft is launching a $25 million initiative to use artificial intelligence to build better technology for people with disabilities.
  • The Artificial Intelligence for accessibility initiative will include seed grants for startups, nonprofit organizations and academic researchers.
  • Deeper investments and expertise from Microsoft researchers will also be provided.
  • Microsoft has experimented with accessibility tools, such as a “Seeing AI” Smartphone app using computer vision and narration to help people navigate if they’re blind or have low vision.
  • Microsoft’s translation tool also provides deaf users with real-time captioning of conversations.

Rariphotic Zone off the coast of Bermuda

  • Oxford scientists have discovered an ocean zone off the coast of Bermuda with over 100 species new to science.
  • The Rariphotic Zone (rare light zone) extends from 130 meters to 300 meters in depth.
  • The zone joins five other areas which have distinct biological communities living and growing within them.

                       

  • Tanaids - minute crustaceans - dozens of new algae species and black wire coral that stand up to two meters high are some of the new species found.
  • The team has also discovered a major algal forest on the summit of an underwater mountain 24 km off the coast of Bermuda.
  • There are over 100,000 underwater mountains in seas across the globe yet less than 50 have been biologically sampled in detail

Purifying water using sunlight

  • Scientists have developed a new technology that uses the sunlight to purify water with near-perfect efficiency.
  • Researchers developed a method that used black, carbon-dipped paper in a triangular shape and using it to both absorb and vaporize water.
  • It is simple, and the power source - the sun - is available everywhere.
  • This technique uses low cost materials against developing advanced materials, such as metallic plasmonic and carbon-based nanomaterials.
  • The low-cost technology described could provide drinking water in regions where resources are scarce, or where natural disasters have struck.

Share of tourism in green house gas emission

  • The team led by researchers at the University of Sydney in Australia found out that global comprehensive tourism footprint of tourism-related greenhouse gas emissions is larger than previously estimated.
  • The world’s domestic and international tourism industry contributes to 8% of the global greenhouse gas emissions.
  • It is about four times greater than previously estimated.
  • Small islands attract a disproportionate share of carbon emissions through international arrivals.
  • The U.S. is responsible for the majority of tourism-generated emissions overall.
  • It is growing faster than international trade and is already responsible for almost a tenth of global GHGs.
