The need of a close relation between disaster risk reduction and the health sector has been highlighted at the 68th World Health Assembly on the basis of the Sendai Framework for Disaster Risk Reduction 2015-2030.

“The Sendai Framework is an opportunity for countries to shift their focus from managing disasters to managing risks which requires a better understanding of risk in all its dimensions of and exposure, a key priority for disaster risk reduction over the next fifteen years. […] The health status of disaster-exposed populations is central to the achievement of the overall goal of the Framework of achieving a substantial reduction of disaster risk and losses in lives, livelihoods and health,” stated Ms. Chadia Wannous, UNISDR’s health focal point.

She stressed the importance of building stronger cooperation between health... read more

High-resolution global soil moisture map from SMAP (Image: NASA)

NASA's new Soil Moisture Active Passive (SMAP) mission has begun science operations. SMAP investigates global soil moisture and detect whether soils are frozen or thawed. This information help scientist understand links among Earth’s water, energy and carbon cycles. In addition, map global soil moisture can help to monitor and predict natural hazards like floods and droughts.

"Fourteen years after the concept for a NASA mission to map global soil moisture was first proposed, SMAP now has formally transitioned to routine science operations," said Kent Kellogg, SMAP project manager at Jet Propulsion Laboratory (JPL). "SMAP's science team can now begin the important task of calibrating the observatory's science data products to ensure SMAP is meeting its requirements for measurement... read more

Australia's Bureau of Meteorology predicted that at the end of this year a strong El Nino effect can bring extreme weather around the world. Computer models based on satellite and meteorological observation data made this prediction.

An El Nino comes along about every two to seven years as part of a natural cycle. It is a warming of the Pacific Ocean as part of a complex cycle linking atmosphere and ocean.

To predict an El Nino scientist designed complex computer models that are fed with satellite and meteorological observation data as well as information about the... read more

Flood affected areas will suffer under the loss of rain fall satellites (Image: United States Marine Corps)

Currently, there are 10 satellites dedicated to monitoring rainfall, but soon this number is likely to fall: four satellites have already passed their design life and others will follow soon. This will strongly affect flood management globally, shows a study published at Environmental Research Letter.

Space-based rainfall observation give high-value opportunities for globally coordinated data services regarding rainfall and resulted floods. Rainfall satellite data provides a good understanding of high-intensity events like monsoon rains, meaning that flood warnings could be communicated and... read more

Space-based monitoring helps track changes on large scales (Image: NASA)

Based on the findings of a scientific review of the draft SDGs, the experts have presented in the International weekly journal of science, Nature, five main priorities they recommend the scientific community to follow. These are: Devise metrics, establish monitoring mechanisms, evaluate progress, enhance infrastructure and standardize and verify data.

Within the priority of enhancing infrastructure, Earth observation and space-based monitoring play an important role. Together with on-the-ground observation, they could help track changes on large scales in natural-resource availability, landscape patterns and management, and social structure.

The authors also emphasize on the... read more

Moving out on Landsat 9 is a high priority for NASA and USGS (Image: NASA)

NASA and the U.S. Geological Survey (USGS) have started work on Landsat 9, planned to launch in 2023, to continue the observing programme of Earth’s land cover. Since 1972 one of the eight satellites in the Landsat program has photographed the entire Earth every 16 days and provide accurate measurements of Earth’s surface.  

With this big data, derived from decades of observations, scientists can for example tease out changes in ecosystems like deforestation in South America, the effects of climate change and many... read more

The technological improvements of the past decade have brought into scene a faster and more efficient way of working with Landsat satellite data.

Scientists and students can now spend more time analysing and evaluating instead of compiling and sorting data from satellites. The modernization of the remote sensing research process has occurred thanks to two main factors: the growth of computing power and the public and free availability of Landsat archives from 2009.

The Landsat record provides the longest continuous view of Earth’s landscape from Space, with at least one image of every location on... read more

Smartphones can detect ground motion and warn others before strong shaking arrives (Image: NASA/Emiliano Rodriguez Nuesch)

A study led by scientists at the U.S. Geological Survey (USGS) has shown smartphones and other personal electronic devices could be used as early warning systems for large earthquakes.

This technology would be especially useful for regions that cannot afford the high prices of conventional early warning systems. Despite being less accurate than scientific-grade equipment, the GPS (Global Positioning System) receivers in a smartphone can detect the permanent ground movement caused by fault motion in a large earthquake, according to USGS.

Crowdsourced observations from participating users are an essential part of the earthquake warning system. “Crowdsourced data are less precise, but for larger... read more
