Amazônia-1 is the first Earth Observation satellite completely designed, integrated, tested and operated by Brazil. It features the optical Advanced Wide Field Imager (AWFI), with swath width 850 km and 60 m resolution, capturing images in 3 visible bands and 1 near-infrared (NIR) band. It has a high revisit period of 5 days, which is important for increasing the probability of capturing useful images over frequently overcast areas including the Amazon region. The data will be accessible to the scientific community, government agencies, and to users interested in a better understanding of the terrestrial environment. The Amazon mission is planned to have three remote sensing satellites: Amazonia-1, followed by Amazonia-1B and Amazonia-2.

Peru’s first Earth Observation satellite was commissioned by the Peruvian government for its national space agency, CONIDA (Comisión Nacional de Investigación y Desarrollo Aeroespacial) in 2014, and constructed in a record time of less than 24 months. PerúSAT-1 features the very-high-resolution optical New AstroSat Optical Modular Instrument (NAOMI) imager designed and developed by Airbus Defence and Space. This silicon carbide optical instrument provides panchromatic images with 70 cm spatial resolution and multispectral images in up to 2 m spatial resolution. PerúSAT-1 is based on Airbus Defence and Space’s AstroBus-S platform, and captures up to 300 images covering an area of 63, 000 km2 per day.

ESA’s Soil Moisture and Ocean Salinity (SMOS) mission is dedicated to making global observations of soil moisture over land and salinity over oceans.

The SMOS satellite carries a novel interferometric radiometer that operates in the L-band microwave range to capture ‘brightness temperature’ images.

These images are used to derive global maps of soil moisture every three days, achieving an accuracy of 4% at a spatial resolution of about 50 km. Over oceans, SMOS maps salinity down to 0.1 practical salinity units (psu, averaged over 10–30 days in areas measuring 200 × 200 km).

According to the latest issue of an annual disaster statistics report, floods were the deadliest type of disasters in 2019, followed by extreme temperature, while storms affected the highest number of people. Published by the Centre for Research on the Epidemiology of Disasters (CRED), “Natural disasters 2019 - Now is the time to not give up” draws on data recorded in the Emergency Events Database (EM-DAT), which saw the addition of 396 disasters that affected a total of 95 million and caused $103 billion in economic losses around the world. 

Accounting for 40 per cent of disaster events, Asia suffered the highest impact with 45 per cent of deaths and 74 per cent of total affected. India, which saw cyclone Fani cause destruction in 2019, was the country most affected... read more

Nepalese Space Research Association (NESRA) is organizing a webinar “Space Technologies for Efficient Disaster Management”, which will be led by distinguished people who have worked to mitigate the effects of disasters using space technologies. The seminar is concerned with how space technologies contribute to efficient disaster management, especially in the wake of the recent flood and landslide risks in Nepal. The benefits of space technologies in the prevention and mitigation of natural disasters will be highlighted.   The main speakers will be:  
  • Abhas Maskey, BIRDS-3 Satellite Project Manager (first satellite of Nepal)
  • Reshma Shrestha, Asst. Professor, Department of Geomatics Engineering, Kathmandu University, Nepal
  The moderator will be:  
  • Anmol Mittal, President, Nepalese Space Research Association (NESRA)

World Congress on Disaster Management (WCDM) is a unique initiative of DMICS to bring researchers, policy makers and practitioners from around the world in the same platform to discuss various challenging issues of disaster risk management. The mission of WCDM is to promote interaction of science, policy and practices to enhance understanding of risks and advance actions for reducing risks and building resilience to disasters.

The Conference will discuss various topics, including:

  • Remote Sensing, GIS and Drones for Disaster Risk Management
  • Early Warning of Hydro-Meteorological Disasters: Tasks Ahead
  • Early Warning of Earthquakes: How Far, How Near
  • Operationalising Early Warning of Landslides
  • Application of Artificial Intelligence for Managing Risks of Disasters
  • Emerging Technologies for Climate & Disaster Resistant Agriculture
The Conference will provide in-depth analysis of the following... read more
