Tourism unaffected by tobacco control

Source: Hong Kong Information Services

The Health Bureau today expressed regret over the inaccurate and misleading content in a report published by Sing Tao Daily on April 3 which quoted individuals’ remarks on alternative smoking products (ASPs) and waterpipe tobacco.

The bureau rebutted the report’s claim that tobacco control policies would negatively impact tourists’ perceptions, saying that it fully considered the tourism sector’s situation when formulating the 10 short-term tobacco control measures which will not affect tourists’ willingness to visit Hong Kong.

Regarding ASPs, it highlighted that Hong Kong has prohibited the import of ASPs, including e-cigarettes and heated tobacco products as well as any related devices, parts and accessories since April 2022. Both the sale or possession of ASPs for commercial purposes are also illegal, while possession for personal use remains permitted.

Tourists therefore, have been unable to bring ASPs into Hong Kong or purchase them upon arrival for three years. Three years after the implementation of the ban, Hong Kong’s tourism sector has not been adversely affected and the number of passenger arrivals last year has even returned to pre-pandemic levels, with the number of passenger arrivals at land boundary control points exceeding pre-pandemic levels.

Additionally, Thailand and Singapore have also banned ASPs without any noticeable impact on their tourism numbers.

The bureau pointed out that claims that the Hong Kong Special Administrative Region Government’s plan to further prohibit the possession of ASPs would deter tourists totally disregarded the fact that ASPs have already been banned from import and sale for three years.

It added that the report also omitted to explain the fact that tourists are currently unable to bring ASPs into Hong Kong or purchase them upon arrival, misleading both the public and tourists.

Moreover, ASPs are by no means “harm-reducing” products, as the report suggested. In fact, ASPs have been proven to release various toxic substances that can cause cancer, and damage the nervous and respiratory systems. The World Health Organization has also clearly stated that there is no evidence to suggest that ASPs could help with quitting smoking.

The bureau also pointed out that e-cigarette devices have been recently used as tools for drug abuse by way of inserting psychoactive substances such as etomidate, commonly known as “space oil”, and heating to generate aerosol for smoking. Young people may become addicted to drugs by smoking e-cigarettes containing “poisonous capsules” without realising it.

The bureau has proposed banning the possession of related products to prevent harmful products like ASPs from continuing to circulate locally and to tackle the problem of “poisonous capsules” at its root.

As for flavoured tobacco products, the Government’s proposed legislation to ban the sale of flavoured conventional smoking products, which also applies to waterpipe tobacco, will not affect tourists visiting Hong Kong.

The proposal is to ban the sale of flavoured conventional smoking products, but not their consumption. 

Inbound travellers, including tourists, are still permitted to bring into Hong Kong 19 cigarettes duty-free or declare and pay duty on cigarettes exceeding this quantity under the existing mechanism, regardless of whether the cigarettes are flavoured or not.

The bureau reiterated that tourists and outside talent would consider a variety of factors when deciding to come to Hong Kong, such as overall tourism experience, development opportunities, humanistic literacies, quality of environment. Tobacco control work will not in any way affect the desire of tourists to visit Hong Kong.

On the contrary, the work will enable citizens and tourists to enjoy a fresher environment, in addition to making Hong Kong a healthier and more vibrant city, thereby enhancing the attractiveness to tourists and outside talent, which is also welcomed by most of the general public, it added.

Lancement d’un fonds de soutien en faveur des associations environnementales

Source: Gouvernement de la Nouvelle-Caledonie

Jérémie Katidjo Monnier, membre du gouvernement chargé de la transition écologique et du changement climatique, a annoncé le lancement du Fonds de soutien de la Nouvelle-Calédonie aux associations œuvrant pour la biodiversité. D’un montant de 200 millions de francs sur deux ans, ce nouveau dispositif vise à accompagner les associations  environnementales dans la sauvegarde de leurs emplois et le maintien de leurs activités pour la préservation des écosystèmes calédoniens.

Les évènements de mai 2024 ont lourdement affecté les associations du secteur environnemental calédonien. Outre les dégâts matériels que certaines ont subis, ces structures n’ont pas bénéficié des dispositifs de soutien financier aux entreprises. Elles ont ensuite souffert de la baisse des subventions qu’elles recevaient en temps normal. En conséquence, de nombreux projets ont été annulés, suspendus ou reportés, fragilisant davantage le tissu associatif.

Aujourd’hui, la survie de plusieurs structures est menacée et nécessite un soutien rapide des pouvoirs publics.

Un fonds pour assurer la pérennité des missions des associations environnementales

Le tissu associatif joue un rôle crucial, à la fois écologique et socio-économique, dans la préservation des espaces naturels terrestres et marins de la Nouvelle-Calédonie. En effet, de nombreuses associations calédoniennes de protection de la nature remplissent de véritables missions d’intérêt général, allant de la régénération de nos forêts à la protection de nos récifs, en passant par la sensibilisation des plus et moins jeunes à la protection de notre environnement. Elles assurent en outre de nombreux emplois directs et indirects, en travaillant en collaboration avec des bureaux d’études, en se fournissant auprès d’entreprises locales.

Conscient de ces enjeux et après plusieurs mois de dialogue et de concertation avec les associations, le gouvernement a souhaité apporter une réponse à la hauteur des défis rencontrés, pour sauvegarder les emplois, maintenir l’expertise en Nouvelle-Calédonie, et préserver le tissu associatif indispensable à la cohésion sociale.

Il a ainsi mis en place un fonds exceptionnel de 200 millions de francs confié à l’Agence Néo-Calédonienne de la biodiversité (ANCB) et destiné à financer des projets retenus dans le cadre d’un appel à projets.

« Il était essentiel pour nous au gouvernement, de mettre en place un fonds géré de manière collégiale au sein de l’ANCB, pour que le monde associatif dans son ensemble, puisse être aidé en ce qui concerne les sujets environnementaux », a expliqué Jérémie Katidjo Monnier. « Ce fonds a été créé sur mesure pour répondre aux besoins de ces associations », a-t-il ajouté.

 

Thibaut Bizien, co-président du collectif des associations de Nouvelle-Calédonie, a salué cette initiative et espère que « d’autres dispositifs de ce type pourront émerger pour des associations qui œuvrent dans d’autres secteurs parce que c’est absolument essentiel pour le tissu associatif ».

L’appel à projets

Publié sur le site de l’ANCB, cet appel à projets destiné aux associations a pour objectifs :

  • de maintenir leurs activités essentielles de préservation et de restauration des écosystèmes, des habitats et des espèces ;
  • de relancer des projets suspendus ou annulés en raison des difficultés financières ;
  • de développer de nouvelles initiatives répondant aux enjeux environnementaux prioritaires en Nouvelle-Calédonie.

Thématiques ciblées

Les projets proposés doivent répondre aux objectifs de réduction des pressions sur la biodiversité identifiées par la Plateforme intergouvernementale scientifique et politique sur la biodiversité et les services écosystémiques (IPBES) : le changement d’usage des sols, la surexploitation des ressources et le trafic illégal, le changement climatique, les pollutions (terre, air, mer), les espèces exotiques envahissantes.

Les projets doivent notamment contribuer à :

  • Protéger et restaurer des écosystèmes, notamment face à la pression du feu ;
  • Favoriser la résilience des écosystèmes face aux pressions anthropiques et aux changements climatiques ;
  • Mettre en œuvre des solutions fondées sur la nature, telles que la restauration écologique, la reforestation ou la réhabilitation de zones humides ;
  • Mobiliser les parties prenantes ;
  • Promouvoir la sensibilisation, l’éducation et la formation autour des enjeux de biodiversité ;
  • Encourager l’engagement citoyen à travers des initiatives locales, collaboratives et participatives ;
  • Engager des changements structurels permettant à contribuer à inverser la trajectoire d’effondrement de la biodiversité en suscitant des transformations profondes dans les pratiques et comportements.

Montant des subventions

L’appel à projets prévoit :

  • un financement compris entre 200 000 et 10 millions de francs par projet, sauf exceptions justifiées par leur envergure ou leur impact stratégique.
  • que les projets bénéficiant d’un co-financement seront valorisés, mais l’aide pourra couvrir jusqu’à 100 % des besoins financiers, en fonction des critères d’évaluation et des priorités définies.

Anne-Sophie Carnuccini, directrice de l’Agence néo-calédonienne pour la biodiversité  (ANCB) à qui a été confiée la gestion de ce fonds, a précisé que l’agence « proposera également un accompagnement pour aider les  associations à monter leur dossier de candidature, mais aussi durant la mise en œuvre des projets pour faire des points d’étape et valoriser leurs actions ».

« Nous prendrons en compte toutes les dépenses des associations, tant que le projet est cohérent et répond aux objectifs de l’appel à projets », a-t-elle assuré.

HKSAR Government expresses strong disapproval of US’s imposition of so-called reciprocal tariff on products of Hong Kong 
     “In 2023, the US was the third largest trading partner of Hong Kong, with the total merchandise trade value amounting to US$60.3 billion. During the past 10 years, the US has realised a trade surplus of US$271.5 billion with Hong Kong, the largest among its global trading partners. The US’s measures are mere unilateral protectionism that harm the interests of all,” the spokesman added.
 
     As for the duty-free de minimis treatment for postal items despatched from Hong Kong to the US, the US has been repeatedly changing its policies unilaterally. Hongkong Post has requested the postal administration of the US to promptly clarify the matter and should not cause inconvenience to the public. From now until May 2, Hongkong Post will temporarily maintain postal services to the US but will not collect any so-called tariffs on behalf of the US authorities.Issued at HKT 20:07

Seaweed: A Nutritional Powerhouse From The Ocean

Source: Government of India

Posted On: 03 APR 2025 5:31PM by PIB Delhi

Summary

  • Seaweed is a nutrient-rich marine plant, packed with vitamins, minerals and amino acids.
  • It contains 54 trace elements and essential nutrients that help fight diseases like cancer, diabetes, arthritis, heart problems and high blood pressure.
  • Seaweed is a sea plant that grows in the ocean and seas.
  • Seaweed cultivation requires no land, freshwater, fertilizers or pesticides, making it sustainable.
  • The $5.6 billion seaweed industry is booming, with India’s production increasing steadily.
  • Under one of its components, the Pradhan Mantri Matsya Sampada Yojana (PMMSY) aims to boost seaweed production to 1.12 million tonnes in five years.

Introduction

India, blessed with a 7,500 km-long coastline, stands at the edge of the ocean’s vast potential. The seashores hold untapped treasures beneath the waves, offering rich resources beyond traditional fisheries. Among these, seaweed farming is emerging as a booming livelihood option, unlocking new opportunities for coastal communities.

Seaweed is a type of marine plant that grows in oceans and seas. It is used in many products like food, cosmetics, fertilizers and even in medicine. It grows in shallow waters and doesn’t require land or freshwater, making it an eco-friendly crop. It’s becoming popular worldwide as a healthy food because it’s easy to grow and needs little care. Seaweed is rich in vitamins, minerals, and amino acids. It helps fight diseases like cancer, diabetes, arthritis, heart problems and high blood pressure. It also boosts immunity and keeps the body healthy.

Unlocking the Potential of Seaweed

Seaweed isn’t just for eating—it’s also used in industries for making thickening and gelling agents:

  • Alginate (US$ 213 million): Extracted from brown seaweeds (harvested from the wild). It’s used as a thickener in foods, cosmetics, and even medical products.
  • Agar (US$ 132 million): Comes from red seaweeds. It’s been cultivated since the 1960s and is used in desserts, jams, and laboratory cultures.


Carrageenan (US$ 240 million): Extracted from certain red seaweeds like Irish Moss. It’s used in dairy products, ice creams, and toothpaste.

Seaweed has been used as food since the 4th century in Japan and the 6th century in China. Today, Japan, China and South Korea are the biggest consumers of seaweed. The global seaweed industry—including food, industrial products and extracts—is valued at around US$ 5.6 billion. According to a World Bank report, 10 emerging seaweed markets could grow by up to US$ 11.8 billion by 2030.

Promoting Seaweed Farming in India

Seaweed has the potential to address the challenge of nutritional deficiency in India. Out of around 844 seaweed species, about 60 are commercially valuable. The government, along with the National Fisheries Development Board (NFDB), is working to boost this sector through policies, infrastructure support, and collaborations with states and research institutes.

In June 2020, the Government of India launched the PMMSY (Pradhan Mantri Matsya Sampada Yojana) with an investment of ₹20,050 crore to boost the fisheries sector. Seaweed farming is a key focus under this scheme. The government has allocated a total budget of Rs. 640 crore for seaweed cultivation in India from 2020 to 2025. This significant investment is aimed at boosting the seaweed industry and promoting sustainability. Out of this total, Rs. 194.09 crore is being used for key projects, including the establishment of a Multipurpose Seaweed Park in Tamil Nadu and the development of a Seaweed Brood Bank in Daman and Diu. So far, 46,095 rafts and 65,330 monocline tubenets have been approved for seaweed farming. Under the PMMSY scheme, India aims to boost seaweed farming, increasing production to 1.12 million tonnes in the next 5 years.

Key Benefits of Seaweed Production

Seaweed production offers a range of environmental and economic benefits. It supports sustainable livelihoods and helps boost the economy.

  1. Biostimulants in Farming: Seaweed is one of the eight types of biostimulants, which help increase crop yields, improve soil health and make plants stronger. The Government of India regulates the quality of seaweed used as biostimulants under the Fertilizer (Control) Order, 1985.

A biostimulant is a natural substance or microorganism that helps plants grow stronger. It improves the plant’s ability to absorb nutrients and makes them more resistant to stress, like drought or diseases. Unlike fertilizers or pesticides, biostimulants don’t provide nutrients directly but enhance the plant’s natural processes for better growth and health.

  1. Support for Organic Farming: Since 2015-16, the government has encouraged organic farming through schemes like Paramparagat Krishi Vikas Yojana (PKVY) and Mission Organic Value Chain Development for the Northeast (MOVCDNER), promoting seaweed-based organic fertilizers for farmers.
  2. Ecological Importance: Seaweed farming is eco-friendly as it helps fight climate change by absorbing CO₂ from the air. Seaweed also improves ocean health by cleaning the water and providing homes for marine life.
  3. Economic Benefits: Seaweed farming offers a new way to earn money besides fishing. For example, farming Kappaphycus alvarezii can earn farmers up to ₹13,28,000 per hectare per year. Seaweed products like biofuels and fertilizers are in high demand globally, helping India earn foreign currency.

Key Seaweed Developments in India

Success Stories

Empowering Women Through Seaweed Farming

Jeya Lakshmi, Jeya, Thangam, and Kaleeswari from Mandapam, Tamil Nadu, were homemakers from poor families struggling to make ends meet. After attending a seaweed farming training under the PMMSY scheme, they decided to start their own business. With an investment of ₹27,000 and financial support from Tamil Nadu State Apex Fisheries Co-operative Federation Limited (TAFCOFED), they began seaweed cultivation. Despite challenges like cyclones, nutrient issues, and marketing hurdles, they managed to produce 36,000 tonnes of wet seaweed. This not only made them financially independent but also created jobs for other women in their community, inspiring many to pursue seaweed farming.

Boosting Seaweed Production with Tissue Culture

The CSIR-Central Salt and Marine Chemicals Research Institute (CSIR-CSMCRI) introduced a tissue culture technique to mass-produce Kappaphycus alvarezii (elkhorn sea moss) in Tamil Nadu. This seaweed is valuable for producing carrageenan, used in food, pharma, and cosmetics. Through this project, tissue-cultured seedlings were distributed to farmers in Ramanathapuram, Pudukottai, and Tuticorin districts. Farmers produced 30 tonnes of seaweed in just two cycles, with a 20-30% higher growth rate and better-quality carrageenan. This breakthrough is set to boost commercial seaweed farming in India.

Conclusion

Seaweed farming can improve the lives of India’s coastal communities by creating jobs and increasing incomes. It’s a sustainable alternative to traditional fishing, especially for women and youth. While challenges like climate risks and market access exist, government schemes like PMMSY and the Seaweed Park in Tamil Nadu are helping the industry grow. With more support and innovation, seaweed farming can boost India’s economy and build a greener future for coastal areas.

PARLIAMENT QUESTION: ESTABLISHMENT OF THIRD LAUNCH PAD

Source: Government of India

Posted On: 03 APR 2025 5:13PM by PIB Delhi

A Third Launch Pad (TLP) will be established at Sriharikota. The project has been approved by the Union Cabinet and financial sanction has been obtained for a total budget outlay of ₹3984.86 Crore. Establishment of the pad is envisaged to be completed within 4 years timeframe.

ISRO’s Next Generation Launch Vehicle (NGLV), which is under development is about 90 m tall with a maximum lift-off mass of approximately 1000 tonne. Existing launch pads at Sriharikota cannot launch this class of vehicles. The propellant servicing facilities and the Umbilical Tower of the existing launch pads are not designed to meet the requirements of the new propulsion system based on Liquid Methane.

In view of very large height & size, the next generation of launch vehicles are planned with horizontal integration and transport, which are then tilted onto the launch pad along with a Tiltable Umbilical Tower (TUT). Also, TLP incorporates necessary features in terms of foundation support & servicing requirements for future augmentation towards supporting the launches of India’s Crewed Lunar mission.

The first stage of NGLV is configured with a cluster of 9 engines. The hot testing of this stage is planned at the Launch Pad, thereby eliminating the need for establishing a huge separate facility for stage testing.

This information was given by Dr. Jitendra Singh, Union Minister of State (Independent Charge) for Science and Technology, Earth Sciences, MoS PMO, Department of Personnel, Public Grievances and Pensions, Department of Space and Department of Atomic Energy, in a written reply in the Rajya Sabha today.

Novel method may transform understanding of adsorption & help control industry processes

Source: Government of India

Posted On: 03 APR 2025 5:13PM by PIB Delhi

Researchers have recently shown that using optical tweezer electrophoresis can help us understand how particles stick to surfaces at tiny scales, at shorter time-scales, a phenomenon that is used in applications ranging from coating to water purification.

The adsorption phenomenon is exploited in the industry for coating a product and refers to the adhesion of one material onto the surface of a different material. This phenomenon is also used in water purification to remove pollutants and for colloidal stabilization during the synthesis of food emulsions. Usually, adsorption is detected via changes in mass or volume.

Researchers from the Raman Research Institute, an autonomous institute funded by the Department of Science and Technology (DST), Government of India, studied adsorption by using Laponite clay nanoplatelets (adsorbate) and Latex spheres (adsorbent) to understand how individual particles are adsorbed.

They used optical tweezer electrophoresis, a technique that tracks changes in electrical charge on the adsorbent. The technique of manipulating a micron-sized object using light is known as optical tweezer and was awarded the Nobel prize in Physics in 2018.  The researchers exploited the optical force exerted by a focused laser beam to grab a micron-sized Latex particle suspended in a clay-water mixture.

The researchers then applied an electric field across a clay-water mixture and tracked the movement of the trapped Latex sphere at an extremely fast rate of 30,000 measurements/ second. The adsorption of clay particles transfers charges to the trapped microsphere.

The researchers tracked the change in the effective charges on the trapped sphere due to adsorption. The fast temporal resolution of these measurements allowed monitoring of adsorption events as they occurred, enhancing the understanding of dynamic interactions, and providing a better basis for the study of adsorption mechanisms. These measurements provided insights into the rate and extent of nanoplatelet adsorption. The results published in Soft Matter, the journal of the Royal Society of Chemistry indicated that higher Laponite concentrations accelerated the adsorption process due to increased nanoplatelet availability.

As a quantitative correlative test, the researchers used cryogenic-field emission scanning electron microscopy (cryo-FESEM) to observe the patterns of adsorption of the clay more clearly and to gain a better understanding of the mechanisms of clay adsorption. Cryo-FESEM images of Latex microspheres suspended in water revealed smooth surface textures, indicating no significant adsorption in pure water. However, when the microspheres were immersed in water- clay mixtures, the clay particles adhered onto the microsphere, displaying patches corresponding to clay nanoplatelets.

The size distribution histograms of these patches showed ranges close to 50 and 25 nm, corresponding to small clay aggregates and individual nanoplatelets. The researchers controlled the adsorption process by tuning the interparticle interactions between clay nanoplatelets and Latex sphere using additives, such as common salt and a peptizing agent. They were able to separate the roles of two attractive forces, dispersion and electrostatic, in the adsorption process and noted that optical tweezer based single colloid electrophoresis and cryogenic field emission scanning electron microscopy are reliable, complementary measurements to study adsorption processes.

“The use of optical tweezer-based single-colloid electrophoresis enables real-time tracking of nanoplatelet adsorption on a single particle and enables us to gain insights that were previously inaccessible through other techniques. While electron microscopy provides detailed visualization of the adsorbed particles, it cannot capture the adsorption kinetics. We used electron microscopy to validate our findings,” the first author Vaibhav Raj Singh Parmar, a PhD student at the Raman Research Institute, explained.

The researchers identified non-electrostatic dispersion interactions as the dominant mechanism driving initial nanoplatelet adsorption. At higher clay and ionic concentrations, electrostatic screening accelerated the adsorption of nanoplatelets, aggregates, and gel network strands. These findings provide valuable insights into the adsorption behaviour of clay nanoplatelets and their interactions with colloidal surfaces in different ionic environments.

Prof. Ranjini Bandyopadhyay, lead of RRI’s RheoDLS lab, pointed out, “Our next goal is to enhance the precision of our measurements by integrating optical tweezer electrophoresis with advanced microfluidic techniques. We are currently developing a holographic optical tweezer capable of trapping multiple beads simultaneously, which will enable us to investigate medium-mediated charge transfer between beads made of the same or different materials”.

Such an understanding of adsorption dynamics at small spatial and temporal scales can help industries to gain precise control over the adsorption process, especially in charged materials.

PARLIAMENT QUESTION: USING REMOTE SENSING DATA FOR SOCIAL DEVELOPMENT AND DISASTER MANAGEMENT

Source: Government of India

Posted On: 03 APR 2025 5:12PM by PIB Delhi

Remote sensing data and space technology are widely employed for societal development activities/ programmes. The space technology is utilized in many of the government programmes targeting rural and remote areas of the country. The details of major programmes utilizing space based inputs are as given below:

  • Geospatial technology for supporting MGNREGA Programme (Geo- MGNREGA): The creation of assets and activities under the MGNREGA programme, are being monitored through Satellite data, Geoportal and mobile applications. More than 6.24 crore assets/ activities have been geo-tagged on the Geo-MGNREGA geoportal. Subsequently, Yuktdhara geospatial planning portal is also developed, for decision support towards planning and implementation of new assets or activities. Phase-II of Geo-MGNREGA project monitored changes over three years due to implementation of natural resource management activities in 23 Gram Panchayats (one Gram Panchayat for each state) of MGNREGA.
  • Integrated Watershed Management Programme: ISRO/ DOS has implemented Geospatial solution for monitoring of about 86,000 micro-watersheds under the Integrated Watershed Management Programme (PMKSY-WDC 1.0). Under this, more than 18 lakh watershed development interventions are geotagged. Under PMKSY-WDC 2.0, around 1150 projects are assessed through Bhuvan tools employing high resolution satellite data (Cartosat 2S & 3).
  • Space based Information Support for Decentralized Planning (SIS-DP): Under two phases of this project, very large scale (1:10,000) country level thematic database on Land Use / Land Cover, Drainage, Settlements, Rail & Road and slope is generated using remote sensing data. Visualisation and analytical tools are deployed on ‘Bhuvan Panchayat’ geoportal (https://bhuvanpanchayat.nrsc.gov.in) to facilitate developmental planning at Panchayat / Village level.
  • Rural Road Infrastructure Mapping: The high-resolution satellite data on Bhuvan was used for mapping rural roads under Pradhan Mantri Gram SadakYojana (PMGSY). Database of rural roads is prepared for entire country and PMGSY dashboard is deployed on Bhuvan Web Portal for monitoring the progress by MoRD and State Govt. Officials.
  • Under Pradhan MantriAwasYojana – Housing for All (PMAY-HFA) and Gramin project, a geospatial platform on the Bhuvan portal is developed to streamline the implementation of the (PMAY-HFA) initiative. It helps in managing the construction of homes for 78.64 Lakhs beneficiaries, to monitor progress through five distinct stages of construction and releasing funds based on project advancement.

Under the Disaster Management Support Programme (DMSP) of ISRO/ DoS, ISRO enables the use of space-based inputs for disaster management activities by the respective nodal Ministries/ Departments. Space based inputs are being used in the hazard; vulnerability; risk (HVR) assessment, disaster monitoring, damage assessment, and development of early warning systems for major disasters such as flood, cyclones, landslide, earthquakes and forest fire. Data from Indian Earth Observation satellites such as Resourcesat-2 & 2A, Cartosat-2 Series, Cartosat-3, EOS-04 (RISAT-1A), EOS-06 (Oceansat-3) and INSAT-3DR & 3DS are being used for disaster management support, in addition to the data from various global satellite missions.

During 2024, major floods were monitored using satellite data and about 300 flood inundation maps were provided to various State and Central disaster management agencies. As part of the National Hydrology Project (NHP), ISRO developed spatial flood early warning system for Godavari and Tapi Rivers. Flood alerts were disseminated through Bhuvan-NHP and NDEM Geoportals, and also to AP State Disaster Management Authority, with 2- day lead time and 85% accuracy. Very High Resolution data from India’s RISAT satellite was used for assessing the extent of the Wayanad (Kerala) landslide in July 2024. In the year 2024, tropical cyclones Remal, Asna, Dana and Fengal were monitored with INSAT-3DR, INSAT-3DS and Oceansat-3 data. Active forest fires were detected using satellite data daily 6 to 8 times during the Indian forest fire season in 2024 and the activity is ongoing for the fire season in 2025.

This information was given by Dr. Jitendra Singh, Union Minister of State (Independent Charge) for Science and Technology, Earth Sciences, MoS PMO, Department of Personnel, Public Grievances and Pensions, Department of Space and Department of Atomic Energy, in a written reply in the Rajya Sabha today.
