Junior Science Refresher this is science magazine in india Published this article page no 71 Drones use can help address most of these issues. 86It will also help in finding solutions to: ○ Addressing Increasing food demand with world population predicted to reach 9 billion by 2050; ○ React faster to pest invasions. E.g. in 2020, drones were used in fight against the attack on crops by swarms of locusts in India. ○ Help in future needs of agriculture through micro level resource management to overcome unsuitable farming methods. E.g. In an experiment, drones helped in reducing herbicide use by 52% in a Brazilian soybean field. ○ Help in Smart Agriculture through direct communication between drones and other agricultural equipment. It involves processing of drone inputs to create field maps and sending it to farm equipment. Challenges Unviable Commercial Operation due to small and scattered landholding. E.g. According to the Agriculture Census (2015-16), around 86% farmers in India hold land less than 5 acres. Limited Flight time and range of Drones due to relatively high payloads (20-60 minutes). High Initial costs of drones with maintenance issues. Connectivity issues in rural areas for online coverage. Knowledge and skill issues as it needs specialized skills and knowledge from farmer to utilize drone inputs, Concerns over misuse of drones to infringe privacy and security (especially in border areas). Weather dependence with difficulties to operate in windy or rainy weather. Way Forward With Drone Rules, 2021 and the SOPs, the main challenge of the past, i.e. lack of national laws or rules is taken care of. Further, a PLI scheme for drones would benefit all sectors including agriculture and achieve Indias potential to become a global drone hub by 2030. The Indian Council of Agricultural Research (ICAR) is already working on SENSAGRI, SENsor based Smart AGRIculture through the Indian Agricultural Research Institute (IARI) and partner Institutes to develop indigenous prototype for drone based crop and soil health monitoring system using hyperspectral remote sensing (HRS) sensors. We should further expand the scope of research to study the quality of its operations and fine-tune telecom, skill, and other policies/initiatives to address the challenges of connectivity and skills among others. 7.3. JAMES WEBB SPACE TELESCOPE (JWST) Why in news? Recently, the James Webb Space Telescope, NASAs most powerful telescope, is rocketed into orbit. More on news junior science refresher magazine buy.
