A heatwave refers to surface temperatures being significantly higher than normal for several days at a time.The World Meteorological Organization defines heatwaves as “five or more consecutive days during which the daily maximum temperature surpasses the average maximum temperature by 5°C (9°F) or more”.However, there is no universally accepted definition for heatwaves. Heatwaves are measured relative to the usual weather in an area and the normal temperatures for the season, and so definitional differences are reflective of global climatic variations and the geographically variable nature of heatwaves and their impact. Several countries have adopted their own standards on heatwaves. The India Meteorological Department requires that temperatures should reach at least 40°C in the plains and at least 30°C in the hilly regions, and should reflect an increase of at least 5°C-6°C (or 9°F-10.8°F) above the normal temperature to be classified as a heatwave.The US National Weather Service defines a heatwave as a spell of “abnormally and uncomfortably hot and unusually humid weather” over two days or more.In Denmark, a heatwave occurs when the mean of the highest recorded temperature measured over three consecutive days exceeds 28°C (82.4°F). In Adelaide, Australia, a heatwave is defined as five straight days with temperatures at or above 35°C (95°F), or three consecutive days at or over 40°C (104°F).Heatwaves “may be characterized by low humidity, which may exacerbate drought, or high humidity, which may exacerbate the health effects of heat-related stress, which include heat exhaustion, dehydration and heatstroke”.Experts identify two facets to a heatwave—the physiological (centred on the general thermoregulation of the human body) and the sociological (focused on local adaptations to the climate). “The human thermoregulatory mechanism endeavors to maintain a constant core temperature for the body, which commonly requires that the internal heat generated by metabolism be transferred through the skin and, to a much lesser extent, the lungs to the surrounding atmosphere”.If the atmospheric conditions are such that the removal of body heat is hampered (as it may be during extreme heat events), the body’s core temperature will likely rise and cause health problems, and may culminate in death.

Heatwaves are a global phenomenon; around the world, days are getting hotter more frequently. The proportion of the Earth’s surface area that was subjected to scorching summers (significantly higher than the average temperatures) increased from 1 percent between 1951-80 to over 10 percent between 1981-2010.Record-breaking heat events were experienced in Australia, Argentina, China, Central Asia, large parts of Europe, Mexico, Japan, South Korea and the US in 2016,and there will almost certainly be an increase in frequency, severity, duration and the spatial extent of heatwaves in the future.

The 17 Sustainable Development Goals (SDGs) of the United Nations aim to achieve decent lives for all people on a healthy planet by 2030.

17 Sustainable Development Goals (SDGs)

The 2030 Agenda for Sustainable Development was adopted by all United Nations Member States in 2015. It lays out a blueprint for people and the planet to live in peace and prosperity now and in the future. The agenda calls for urgent action by all the member countries to achieve the following 17 goals (with 169 targets and 304 indicators) by 2030. There are 3 pillars of sustainable development  - economic, social, and environmental. 

People have made mnemonics to remember the SDGs. However a problem with many of them is that you have to learn a bunch of SDGs together. Consider an acronym KOTA for 4 SDGs. Using it, one is not able to recall the SDGs individually - thus it is better to learn each goal individually. I have presented my methods of learning them. A few may seem convoluted. Pick and choose what you like, and for the rest you should make your own.

Bagru printing is one of the traditional techniques of printing with natural colour followed by the chippas of a remote place of Rajasthan. The process starts from preparing the cloth to finished printed fabrics through their indigenous methods. Motifs having some specialty are transferred onto light coloured background with wooden blocks following two styles direct and resist style. Although this technique is facing problems against the threat of globalization, this exotic art of creation is required to be encouraged in the present context of environmental consciousness... #art #culture #upsc #prelims #revision

The Central government introduced the Insolvency and Bankruptcy Code(IBC) in 2016 to resolve claims involving insolvent companies. This was intended to tackle the bad loan problems that were affecting the banking system. Two years on the IBC has succeeded in a large measure in preventing corporates from defaulting on their loans. The IBC process has changed the debtor-creditor relationship. A number of major cases have been resolved in two years, while some others are in advanced stages of resolution.#economy #banking #upsc #prelims
