A Framework for Community-level Disaster Resilience Index: Focus on the Host Communities in Cox’s Bazar Executive Summary The Community-Level Disaster Resilience Index for Cox’s is an adaptation of the Climate Disaster Resilience Index (CDRI), which was introduced by the International Environment and Disaster Management (IEDM) Laboratory of Kyoto University Graduate School of Global Environmental Studies along with its partner organizations, including CITYNET and UNISDR in 2008 to measure disaster resilience of the coastal cities by considering five dimensions: physical, social, economic, institutional, and natural. Then, the variables selection was translated to the local setting, collecting matching variables/indicators and suitable alternatives where necessary. Furthermore, RIMES incorporated the “Rapid Index of Stress to the Rohingya Crisis” into the disaster resilience index. Rapid Index of Stress to the Rohingya crisis is an adaptation of the “Rapid Index of Stress to the Syrian Crisis,” developed by UNDP, considering the Syrian refugee crisis. The framework is mainly developed by identifying an initial list of indicators and variables following an extensive literature search and by using stakeholders’ and experts’ opinions and perceptions to achieve a consensus regarding the key indicators and assigning weights to each in order to assess community resilience and the ability to cope with disasters. This framework employs a combination of both quantitative and qualitative (i.e., public opinions and expert judgments) methods. This study shows various vulnerability types for each of the target communities/unions. Considering the overall resilience, Raja Palong union is comparatively higher than others, whereas Palongkhali union shows the lowest resilience score. Host communities in Ukhiya are concerned about increasing labor competition, deforestation, groundwater depletion, increase in price, and damages to their physical and natural resources. Both individual homes and community shelters are weak and in poor condition. These issues are linked to the region’s poor land quality and high risk of natural disasters. Increasing risk financing opportunities, forecast-based support or bursary on youth/women employment, etc., will enhance the resilience of the communities in Ukhiya, while the risk governance monitoring system may expedite the efficiency of humanitarian and development blending mechanism. Cyclone has been identified as the most high-risk hazardous event of this Upazila. The second most risky and hazardous events include heavy rainfalls, sudden flood, and coastal floods. Water-logging and landslides are regarded as the third most hazardous event. Ukhiya Upazila needs a comprehensive land-use and natural resource management policy that requires a climate and resource footprint assessment to avoid future resource scarcity. The resilience matrix is recommended to be used in the non-refugee hosting areas too. A decision support system (DSS) can be further developed using a variety of resilience indicators and present the output by indicators automatically. This DSS will use union-level Risk Index methodology to generate key decision-making indicators. Some of the future usages of this tool include a systematic and transparent approach to visualize, compare, and rank disaster risk at the community/union level, bridging the science-policy gap through an easy platform that allows both technical and non-technical users to understand risk and resilience, and usage of relevant data to support evidence-based decision-making for disaster risk management.

The U.S. military’s new, expanded combat training of Ukrainian forces began in Germany on Sunday, with a goal of getting a battalion of about 500 troops back on the battlefield to fight the Russians in the next five to eight weeks, said Gen. Mark Milley, chairman of the Joint Chiefs of Staff.

Milley, who plans to visit the Grafenwoehr training area on Monday to get a first-hand look at the program, said the troops being trained left Ukraine a few days ago. In Germany is a full set of weapons and equipment for them to use.

Until now the Pentagon had declined to say exactly when the training would start.

The so-called combined arms training is aimed at honing the skills of the Ukrainian forces so they will be better prepared to launch an offensive or counter any surge in Russian attacks. They will learn how to better move and coordinate their company- and battalion-size units in battle, using combined artillery, armor and ground forces.

Speaking to two reporters traveling with him to Europe on Sunday, Milley said the complex training — combined with an array of new weapons, artillery, tanks and other vehicles heading to Ukraine — will be key to helping the country’s forces take back territory that has been captured by Russia in the nearly 11-month-old war.

“This support is really important for Ukraine to be able to defend itself,” Milley said. “And we’re hoping to be able to pull this together here in short order.”

The goal, he said, is for all the incoming weapons and equipment to be delivered to Ukraine so that the newly trained forces will be able to use it “sometime before the spring rains show up. That would be ideal.”

The new instruction comes as Ukrainian forces face fierce fighting in the eastern Donetsk province, where the Russian military has claimed it has control of the small salt-mining town of Soledar. Ukraine asserts that its troops are still fighting, but if Moscow’s troops take control of Soledar it would allow them to inch closer to the bigger city of Bakhmut, where fighting has raged for months.


Russia also launched a widespread barrage of missile strikes, including in Kyiv, the northeastern city of Kharkiv and the southeastern city of Dnipro, where the death toll in one apartment building rose to 30.


Milley said he wants to make sure the training is on track and whether anything else is needed, and also ensure that it will line up well with the equipment deliveries.

The program will include classroom instruction and field work that will begin with small squads and gradually grow to involve larger units. It would culminate with a more complex combat exercise bringing an entire battalion and a headquarters unit together.

Until now, the U.S. focus has been on providing Ukrainian forces with more immediate battlefield needs, particularly on how to use the wide array of Western weapons systems pouring into the country.

The U.S. has already trained more than 3,100 Ukrainian troops on how to use and maintain certain weapons and other equipment, including howitzers, armored vehicles and the High Mobility Artillery Rocket System, known as HIMARS. Other nations are also conducting training on the weapons they provide.

In announcing the new program last month, Air Force Brig. Gen. Pat Ryder, Pentagon press secretary, said the idea “is to be able to give them this advanced level of collective training that enables them to conduct effective combined arms operations and maneuver on the battlefield.”

Milley said the U.S. was doing this type of training prior to the Russian invasion last February. But once the war began, U.S. National Guard and special operations forces that were doing training inside Ukraine all left the country. This new effort, which is being done by U.S. Army Europe Africa’s 7th Army Training Command, will be a continuation of what they had been doing prior to the invasion. Other European allies are also providing training.

Franco-US Satellite Set for Unprecedented Survey of Earth’s Water

A Franco-U.S. satellite is due for launch this week on a mission to survey with unprecedented accuracy nearly all water on Earth’s surface for the first time and help scientists investigate its impact on Earth’s climate.

For NASA and France’s space agency CNES, which have worked together in the field for 30 years, it’s a landmark scientific mission with a billion-dollar budget.

French President Emmanuel Macron went to NASA’s Washington headquarters at the end of November alongside U.S. Vice President Kamala Harris.

He highlighted the liftoff — scheduled for early Thursday on the U.S. West Coast — of the Surface Water and Ocean Topography (SWOT) mission to monitor the levels of oceans, lakes and rivers, including in remote locations.

Its predecessor, TOPEX/Poseidon, launched in 1992, was also a Franco-U.S. joint venture that measured ocean surface to an accuracy of 4.2 centimeters (1.7 inches).

It aided the forecast of the 1997-1998 El Nino weather phenomenon and improved understanding of ocean circulation and its effect on global climate.

The 2.2-metric ton SWOT mission will be put into orbit from Vandenberg Space Force Base in California atop a SpaceX Falcon 9 rocket.

The satellite’s primary payload is an innovative instrument to measure the height of water called KaRin, or Ka-band radar interferometer. Its two antennas, separated by a big boom, create parallel swaths of data.

“We’re going to get 10 times better resolution than with current technologies to measure sea-surface height and understand the ocean fronts and eddies that help shape climate,” said NASA Earth Science Division Director Karen St. Germain.

“It’s like looking at a car number plate from space when before we could only see a street,” added Thierry Lafon, SWOT project leader at the CNES.

The stakes are high. While the impact of major ocean currents such as the Gulf Stream is known, more local flows and eddies covering dozens of kilometers remain more of a mystery.

But they too affect sea water surface temperatures and heat transfer as well as the absorption by the oceans of carbon dioxide from the atmosphere.

SWOT will improve weather and climate modeling, the observation of coastal erosion and help track how fresh and saltwater bodies change over time.

With an “optimal” orbit of 890 kilometers (about 550 miles) above Earth, Lafon said SWOT will “take in all the components that affect water levels such as tides and the sun.”

NASA said SWOT will survey nearly all water on Earth’s surface for the first time.

It will monitor water levels, surface areas and quantities at more than 20 million lakes with shores of more than 250 meters. The entire length of rivers more than 100 meters wide will also be observed.

Water management, flood and drought prevention will be improved, said Lafon.

Flying the satellite to Vandenberg from the Thales Alenia Space (TAS) site in Cannes, southern France, proved a headache.

“Due to the conflict in Ukraine, there were no more Antonov 124s available, and the 747 cargo is too small,” said TAS project leader Christophe Duplay. “We decided to ask the [U.S. Air Force] to provide one of its C-5 Galaxies.”

And that meant counting on NASA to have the air force supply one of its rare giant aircraft to ship the huge payload.

SWOT has an estimated three-year lifetime — although Lafon said “nothing precludes the mission to last five to eight years” — and is set to become the first satellite to make a controlled reentry into Earth’s atmosphere, reducing the amount of space debris, in line with the French space operations act.

Nearly 80% of the 400 kilos (880 pounds) of onboard fuel will be used to that end.

Explainer: Why Fusion Could Be a Clean-Energy Breakthrough

The Department of Energy planned an announcement Tuesday on a “major scientific breakthrough” at the Lawrence Livermore National Laboratory, one of several sites worldwide where researchers have been trying to develop the possibility of harnessing energy from nuclear fusion.

It’s a technology that has the potential to one day accelerate the planet’s shift away from fossil fuels, which are the major contributors to climate change. The technology has long struggled with daunting challenges.


Here’s a look at exactly what nuclear fusion is, and some of the difficulties in turning it into the cheap and carbon-free energy source that scientists believe it can be.

What is nuclear fusion?

Look up, and it’s happening right above you — nuclear fusion reactions power the sun and other stars.

The reaction happens when two light nuclei merge to form a single heavier nucleus. Because the total mass of that single nucleus is less than the mass of the two original nuclei, the leftover mass is energy that is released in the process, according to the Department of Energy.

In the case of the sun, its intense heat — millions of degrees Celsius — and the pressure exerted by its gravity allow atoms that would otherwise repel each other to fuse.

Scientists have long understood how nuclear fusion has worked and have been trying to duplicate the process on Earth as far back as the 1930s. Current efforts focus on fusing a pair of hydrogen isotopes — deuterium and tritium — according to the Department of Energy, which says that particular combination releases “much more energy than most fusion reactions” and requires less heat to do so.

How valuable would this be?

Daniel Kammen, a professor of energy and society at the University of California at Berkeley, said nuclear fusion offers the possibility of “basically unlimited” fuel if the technology can be made commercially viable. The elements needed are available in seawater.

It’s also a process that doesn’t produce the radioactive waste of nuclear fission, Kammen said.

How are scientists trying to do this?

One way scientists have tried to recreate nuclear fusion involves what’s called a tokamak — a doughnut-shaped vacuum chamber that uses powerful magnets to turn fuel into a superheated plasma (between 150 million and 300 million degrees Celsius) where fusion may occur.

The Livermore lab uses a different technique, with researchers firing a 192-beam laser at a small capsule filled with deuterium-tritium fuel. The lab reported that an August 2021 test produced 1.35 megajoules of fusion energy — about 70% of the energy fired at the target. The lab said several subsequent experiments showed declining results, but researchers believed they had identified ways to improve the quality of the fuel capsule and the lasers’ symmetry.

“The most critical feature of moving fusion from theory to commercial reality is getting more energy out than in,” Kammen said.

Japan’s Ispace Launches World’s First Commercial Moon Lander

 

A Japanese space startup launched a spacecraft to the moon Sunday after several delays, a step toward what would be a first for the nation and for a private company.

Ispace Inc’s HAKUTO-R mission took off without incident from Cape Canaveral, Florida, after two postponements caused by inspections of its SpaceX Falcon 9 rocket.

More than a hundred people at a viewing party in Tokyo roared in applause when the rocket fired and lifted into the dark skies.

“I’m so happy. After repeated delays, it’s good that we had a proper launch today,” said Yuriko Takeda, a 28-year-old worker at an electronics company who joined the gathering.

“I have this image of the American flag from the Apollo landing, so while this is just the launch, the fact that it’s a private company going there with a rover is a really meaningful step.”

The national space agencies of the United States, Russia and China have achieved soft landings on Earth’s nearest neighbor in the past half century, but no companies have.

Mission success would also be a milestone in space cooperation between Japan and the United States at a time when China is becoming increasingly competitive and rides on Russian rockets are no longer available in the wake of Russia’s invasion of Ukraine.

It would also cap a space-filled few days for Japan, after billionaire Yusaku Maezawa revealed on Friday the eight crew members he hopes to take on a SpaceX flyby of the moon as soon as next year.

The name HAKUTO refers to the white rabbit that lives on the moon in Japanese folklore, in contrast to the Western idea of a man in the moon. The project was a finalist in the Google Lunar XPRIZE before being revived as a commercial venture.

Next year is the Year of the Rabbit in the Asian calendar.

The craft, assembled in Germany, is expected to land on the moon in late April.

The company hopes this will be the first of many deliveries of government and commercial payloads. The ispace craft aims to put a small NASA satellite into lunar orbit to search for water deposits before touching down in the Atlas Crater.

The M1 lander will deploy two robotic rovers, a two-wheeled, baseball-sized device from Japan’s JAXA space agency and the four-wheeled Rashid explorer made by the United Arab Emirates.

It will also be carrying an experimental solid-state battery made by NGK Spark Plug Co.

“The Rashid rover is part of the United Arab Emirates ambitious space program,” said Dubai ruler Sheikh Mohammed bin Rashid al-Maktoum, who is also vice president of the United Arab Emirates and who watched the launch at the Mohammed bin Rashid Space Centre.

“Our aim is knowledge transfer and developing our capabilities and to add a scientific imprint in the history of humanity,” he tweeted.

Privately funded ispace has a contract with NASA to ferry payloads to the moon from 2025 and is aiming to build a permanently staffed lunar colony by 2040.

NASA Moon Capsule Orion Due to Splash Down After Record-Setting Voyage

After making a close pass at the moon and venturing further into space than any previous habitable spacecraft, NASA’s Orion capsule is due to splash down Sunday in the final test of a high-stakes mission called Artemis.

As it hurtles into Earth’s atmosphere at a speed of 40,000 kph, the gumdrop-shaped traveler will have to withstand a temperature of 2,800 degrees Celsius — about half that of the surface of the sun.

Splashdown in the Pacific off the Mexican island of Guadalupe is scheduled for 1739 GMT (9:39 am local time).

Achieving success in this mission of just over 25 days is key for NASA, which has invested tens of billions of dollars in the Artemis program due to take people back to the moon and prepare for an onward trip, someday, to Mars.

So far, the first test of this uncrewed spacecraft has gone very well.

But it is only in the final minutes of this voyage that the true challenge comes: seeing if Orion‘s heat shield, the biggest ever built, actually holds up.

“It is a safety-critical piece of equipment. It is designed to protect the spacecraft and the passengers, the astronauts on board. So the heat shield needs to work,” said Artemis mission manager Mike Sarafin.

A first test of the capsule was carried out in 2014 but that time the capsule stayed in Earth’s orbit, so it came back into the atmosphere at a slower speed of around 32,000 kph.

Choppers, divers and boats

A U.S. Navy ship, the USS Portland, has been positioned in the Pacific to recover the Orion capsule in an exercise that NASA has been rehearsing for years. Helicopters and inflatable boats will also be deployed for this task.

The falling spacecraft will be slowed first by the Earth’s atmosphere and then a web of 11 parachutes until it eases to a speed of 30 kph when it finally hits the Pacific.

Once it is there, NASA will let Orion float for two hours — a lot longer than if astronauts were inside — to collect data.

“We’ll see how the heat soaks back into the crew module and how that affects the temperature inside,” said Jim Geffre, NASA’s Orion vehicle integration manager.

Divers will then attach cables to Orion to hoist it onto the USS Portland, which is an amphibious transport dock vessel, the rear of which will be partly submerged. This water will be pumped out slowly so the spacecraft can rest on a platform designed to hold it.

This should all take about four to six hours from the time the vessel first splashes down.

The Navy ship will then head for San Diego, California, where the spacecraft will be unloaded a few days later.

When it returns to Earth, the spacecraft will have traveled more than 2 million kilometers since it took off Nov. 16 with the help of a monstrous rocket called SLS.

At its nearest point to the moon, it flew less than 130 kilometers from the surface. And it broke the distance record for a habitable capsule, venturing 432,000 kilometers from our planet.

Artemis 2 and 3

Recovering the spacecraft will allow NASA to gather data that is crucial for future missions.

This includes information on the condition of the vessel after its flight, data from monitors that measure acceleration and vibration, and the performance of a special vest put on a mannequin in the capsule to test how to protect people from radiation while flying through space.

Some components of the capsule should be good for reuse in the Artemis 2 mission, which is already in advanced stages of planning.

This next mission planned for 2024 will take a crew toward the moon but still without landing on it. NASA is expected to name the astronauts selected for this trip soon.

Artemis 3, scheduled for 2025, will see a spacecraft land for the first time on the south pole of the moon, which features water in the form of ice.

Only 12 people — all of them white men — have set foot on the moon. They did this during the Apollo missions, the last of which was in 1972.

Artemis is scheduled to send a woman and a person of color to the moon for the first time.

NASA’s goal is to establish a lasting human presence on the moon, through a base on its surface and a space station circling around it. Having people learn to live on the moon should help engineers develop technologies for a years-long trip to Mars, maybe in the late 2030s.

WHO: Trial Sudan Ebolavirus Vaccine Marks Historical Milestone

The World Health Organization says the arrival of one of three trial Ebola vaccines in Uganda Thursday “marks a historical milestone in the global capacity to respond to outbreaks.”

The 1,200 doses of the Sudan ebolavirus vaccine arrived “just 79 days after the outbreak was declared on 20 September,” the WHO said.

“Uganda is showing that life-saving research can be promptly organized in the midst of an outbreak,” said Dr. Jane Ruth Aceng Acero, Uganda’s minister of health.

In contrast, WHO said that “To start Phase 3 trials in Guinea during the West Africa Ebola outbreak in 2015, it was 7 months from declaration to arrival of vaccines. This was a great achievement and set historical records at the time.”

The vaccine for the Sudan ebolavirus is one of the three candidates recommended for the trial by an independent WHO expert panel. The other two will be added to the trial when the doses arrive.

Storm Brings High Winds, Heavy Snow to Northern California

A winter storm packing high winds and potentially several feet of snow blew into the Sierra Nevada on Saturday, triggering thousands of power outages in California, closing a mountain highway at Lake Tahoe, and prompting an avalanche warning in the backcountry.

The storm is expected to bring as much as 1.2 meters of snow to the upper elevations around Lake Tahoe by Monday morning, the National Weather Service said.

A 400-kilometer stretch of the Sierra from north of Reno to south of Yosemite National Park was under a winter storm warning at least until Sunday.

“Travel will be very difficult to impossible with whiteout conditions,” the weather service said in Reno, where rain started falling Saturday.

A flood advisory was in effect from Sacramento to the California coast near San Francisco.

The U.S. Forest Service issued an avalanche warning for the backcountry in the mountains west of Lake Tahoe where it said “several feet of new snow and strong winds will result in dangerous avalanche conditions.”

A stretch of California Highway 89 was closed because of heavy snow between Tahoe City and South Lake Tahoe, California, the highway patrol said. Interstate 80 between Reno and Sacramento remained open, but chains were required on tires for most vehicles.

More than 30,000 customers were without power in the Sacramento area at one point Saturday morning. It had been restored to all but about 3,300 by midday. But forecasters warned winds gusting up to 80 kph could bring down tree branches and power lines later in the day.

About 25 centimeters of snow already had fallen at Mammoth Mountain ski resort south of Yosemite where more than 3 meters of snow has been recorded since early November.

“It just seems like every week or so, another major storm rolls in,” resort spokeswoman Lauren Burke said.

The storm warning stretches into Sunday for most of the Sierra and doesn’t expire until Monday around Tahoe.

As much as 45 to 71 centimeters of snow was forecast through the weekend at lake level, and up to 1.2 meters at elevations above 2,133 meters with 80 kph winds and gusts up to 160 kph.

On the Sierra’s eastern slope, a winter weather advisory runs from 10 p.m. Saturday to 10 a.m. for Reno, Sparks and Carson City, with snow accumulations of 2.5-7.5 cm on valley floors and up to 20 cm above 1,524 meters.
