Rwandan President Removes Justice Minister Amid ‘Hotel Rwanda’ Hero Trial

Rwanda’s President Paul Kagame has removed the justice minister but made him ambassador to Britain amid international scrutiny over the trial of Paul Rusesabagina, the hotelier credited with saving many lives during the 1994 genocide.

A government statement issued on Tuesday gave no reason for the dismissal of Johnston Busingye, who had served as justice minister and attorney general since 2013.

Busingye was appointed Rwanda’s ambassador to Britain, the statement said.

Kagame did not immediately name a new justice minister. Requests for comment to government spokespeople and the presidency office were not answered.

Rusesabagina was hailed as hero after he used his connections as the manager of a Kigali hotel to save ethnic Tutsis from slaughter during the genocide. He was portrayed in the 2004 Hollywood film “Hotel Rwanda.”

Now he is accused of nine terrorism-related charges, including forming and funding an armed rebel group. Before his arrest, Rusesabagina, who was living in the United States, was a vocal critic of the Kagame government.

Prosecutors have requested a life sentence for Rusesabagina, whose family says he is in poor health and being mistreated in prison. The court is scheduled to issue its verdict on Sept. 20.

In an interview with Qatar-based Al Jazeera news channel in February, then Minister Busingye said the government had paid for the flight that brought Rusesabagina to Rwanda last year, which Rusesabagina’s family said resulted in his kidnapping.

Rusesabagina’s trial has drawn attention to Kagame, whom rights groups say has used authoritarian tactics to crush political opposition and extend his rule.

The government’s arrest of Rusesabagina amounted to an enforced disappearance, a serious violation of international law, New York-based Human Rights Watch said at the time.

Kagame became head of state in 2000 after he and his rebel forces halted the genocide in 1994 after 100 days of bloodletting and around 800,000 deaths of ethnic Tutsis and moderate Hutus. He won landslide victories in subsequent elections, the most recent in 2017, when he won nearly 99% of the vote. He changed the constitution in 2015, enabling him to rule legally until 2034.

UNDRR welcomes WMO Atlas of Mortality and Economic Losses

STATEMENT BY MAMI MIZUTORI, SECRETARY-GENERAL SPECIAL REPRESENTATIVE FOR DISASTER RISK REDUCTION AT LAUNCH OF WMO ATLAS OF MORTALITY AND ECONOMIC LOSSES FROM WEATHER, CLIMATE AND WATER EXTREMES

I would like to applaud my WMO colleagues under the leadership of Secretary-General Professor Petteri Taalas for producing this timely review of mortality linked to extreme weather events over the last 50 years.

More lives are being saved thanks to early warning systems. We see evidence of this right across the world from the Gulf of Mexico to the Bay of Bengal. Thanks to advances in meteorology, satellite imagery and stronger risk governance, disasters that in the past, would have taken thousands of lives no longer do so.

However, it is also true that the numbers of people affected by disasters is increasing due to population growth in hazard-exposed areas and the growing intensity and frequency of extreme weather events.

July was the hottest month since records began. There are more greenhouse gases in the atmosphere than ever before. The climate emergency is manifesting itself in many unprecedented events around the globe which threaten human health and safety and erode our quality of life.

Last year 31 million people were displaced by disasters. Pre-COVID an estimated 26 million people were pushed into poverty every year by disasters. The pandemic combined with extreme weather events including drought is having devastating effects on global hunger and poverty. 2.3 billion people lacked adequate year-round access to food in 2020.

The overlap of the COVID-19 pandemic with extreme weather events during the last 18 months, demonstrates the need for greater investment in disaster risk reduction and a multi-hazard approach to disaster risk management.

In recent days, we have had a vivid example of the benefits of investing in disaster risk reduction.

On the anniversary of Hurricane Katrina, the city of New Orleans and much of Louisiana faced its greatest challenge when Category 4, Hurricane Ida, made landfall.

The difference this time was that over the last 16 years the city embarked on one of the largest public-works projects in the world.

After Hurricane Katrina devastated New Orleans in 2005, the city designed a new Hurricane and Storm Damage Risk Reduction System which required an investment of $14.5 billion in gates, flood walls and levees that would protect it against another once-in-a-century storm.

One dreads to think of the loss of life and destruction of critical infrastructure that would have ensued in recent days if this system had not been completed three years ago.

Of course, great economic loss and damage to public utilities has resulted from this hurricane but the essential lesson is that the investment in disaster resilient infrastructure has mean that major loss of life has been averted and the extent of economic losses has been mitigated considerably.

I have no doubt that New Orleans and the State of Louisiana will process the learning from this latest disaster and build back better to be even more resilient in the face of the next major hurricane.

Developing countries are not so fortunate when it comes to the resources available to them for investment in disaster resilient infrastructure and multi-hazard warning systems which, together, can both save lives and reduce disruption to everyday life including access to work, schools and health services.

As the Atlas highlights only half of the 193 WMO members have multi-hazard early warning systems and there are severe gaps in weather and hydrological observing networks in Africa, parts of Latin America and in Pacific and Caribbean island states.

Disasters impact developing countries disproportionately resulting in higher loss of life, and greater numbers of people injured, and left displaced and homeless. Their economic losses are also higher as a percentage of GDP.

Many of them struggle to find the resources to implement their national strategies for disaster risk reduction which are a key element of the Sendai Framework for Disaster Risk Reduction, the global plan to reduce disaster losses agreed by UN Member States,

There is no vaccine against poverty. International cooperation to developing countries is essential if many of them are to survive the climate emergency and adapt to the challenges of a warming world which they have done little to create.

The G20 countries must step up to the plate, not only to deliver on their promises to reduce greenhouse gas emissions but to provide financial, technological and capacity building support to developing countries that are struggling to cope with rising sea levels, warming seas, erratic rainfall and the constant threat of extreme weather events.

International cooperation for developing countries will be the theme of this year’s International Day for Disaster Risk Reduction on 13 October. It will be an opportunity to turn the spotlight on the need to strengthen disaster risk governance in developing countries and increase the availability of multi-hazard early warning systems and public access to disaster risk information.

UN Study: Weather Disasters Increased Fivefold in Last 50 Years

A new report released Wednesday by the United Nations indicates extreme weather events have increased fivefold over the past 50 years, while the number of fatalities related to those events has dropped.

Officials from the U.N.’s weather and climate agency, the World Meteorological Organization, introduced the report during a briefing from the agency’s headquarters in Geneva. The report shows weather-related disasters have occurred on average at a rate of one per day over the past five decades, killing 115 people and causing $202 million in losses daily.

Mami Mizutori, U.N. special representative for disaster risk reduction, told reporters she found the report “quite alarming.” She noted that this past July was the hottest July on record, marked by heat waves and floods around the world. The study shows that more people are suffering due to this increased frequency and intensity of weather events.

Mizutori said 31 million people were displaced by natural disasters last year, almost surpassing the number displaced by conflicts. She said on average, 26 million people per year are pushed into poverty by extreme weather events. Now, the COVID-19 pandemic is compounding the problem.

The U.N. disaster risk specialist said, “We live in this, what we call, the multihazard world, and it demonstrates that we really need to invest more in disaster risk reduction and prevention.”

WMO Secretary-General Petteri Taalas said the good news in the report is that during that same period, fatalities related to these disasters dropped by nearly three times, due to early warning systems and improved disaster management.

But the study also shows that more than 91% of the deaths that do occur happen in developing or low-income countries, as many do not have the same warning and management systems in place.

The WMO officials said the economic losses associated with these disasters will worsen without serious climate change mitigation. Taalas said if the right measures are put in place, the trend could be stopped in the next 40 years. WMO called on the G-20 group of world economic powers to keep their promise to reduce greenhouse gas emissions.
