We describe the diversified National Ambient Noise Monitoring Network (NANMN) set up across 7 major cities of India and covering 70 stations for continuous noise monitoring throughout the year. The annual average Lday (06–22 h) and Lnight (22–06 h) values observed in 2015 for these 70 locations are described. Of these, 25 locations are in commercial zones, 12 in industrial, 16 in residential and 17 in silence zones. Each city has 10 noise monitoring stations installed for analysing environmental noise pollution levels round the clock (24  365 h).

The IRTAD (International Traffic Safety Data and Analysis Group) Road Safety Annual Report 2017 provides an overview of road safety performance for 2015 in 40 countries, with preliminary data for 2016, and detailed reports for each country. It includes tables with cross country comparisons on key safety indicators.

Treating cancer with the latest drugs and techniques is costly and will not improve survival globally.

China is the world’s largest consumer of coal, but it also has more wind and solar generation capacity than any other country in the world. This is just one insight drawn from the new and updated edition of Key World Energy Statistics (KWES) released by the IEA. The new version of KWES still provides headline data on all fuels, and now also contains additional information highlighting the rapid growth of renewable technologies, for example that in four countries wind generation provided more than 10% of all electricity, with solar providing more than 5% in two countries.

The Key Indicators presents the latest statistics on a comprehensive set of economic, financial, social, environmental, and Sustainable Development Goal (SDG) indicators for the 48 regional members of the Asian Development Bank. It is designed to serve as a resource for information on development issues across the region for a wide audience, including policy makers, development practitioners, government officials, researchers, students, and the general public.

The latest roadmap to a 100% renewable energy future from Stanford's Mark Z. Jacobson and 26 colleagues is the most specific global vision yet, outlining infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors.

Today's over-60 population is the fastest growing group. Currently, there are around 962 million people aged 60 or over, representing 12.3 per cent of the global population. By 2050, this will increase to 2.1 billion or 21.5 per cent of the global population. But are we taking care of them?

The relationship between macronutrients and cardiovascular disease and mortality is controversial. Most available data are from European and North American populations where nutrition excess is more likely, so their applicability to other populations is unclear.

NITI Aayog launched the Ease of Doing Business report based on an Enterprise Survey of 3,500 manufacturing firms across Indian states and union territories. The survey has been conducted, along with the IDFC Institute, to assess the business regulations and enabling environment across India from firms’ perspective.

Drought events have critical impacts on agricultural production yet there is little consensus on how these should be measured and defined. This has implications for drought research and policy, which tends to either define droughts purely based on rainfall or focus uniquely on 'hot' droughts when temperature is considered.
