A publication from Nature demonstrates that satellite observations of floods reveal that the proportion of the population exposed to floods has grown by 24% globally since the turn of the century. That is 10 times more than scientists previously thought, and they estimate that by 2030, climate and demographic change will add 25 new countries to the 32 already experiencing increasing floods and harsh weather conditions. 

The United Nations has chosen to increase international cooperation for developing countries as the theme of this year’s World Tsunami Awareness Day, on November 5th. The UN Secretary-General designated November 5th as World Tsunami Awareness day back in December 2015, and it is meant to call on all countries, international bodies, and civil society to increase understanding of the deadly threat and share innovative approaches to reduce risks. 

The UN Secretary-General, António Guterres, says that “rising sea levels caused by the climate emergency will further exacerbate the destructive power of tsunamis. We must limit warming to 1.5 degrees over pre-industrial averages and invest at scale in the resilience of coastal communities.” Many regions that experience rapid urbanization and growing tourism are prone to tsunamis, and it puts even more people in harm’s way. 

For World Tsunami Awareness Day in 2021, the theme will be the Sendai Seven Campaign. The Sendai Seven Campaign –"7 targets, 7 years" was launched in 2016 by the United Nations Secretary-General, with the main objective of promoting the seven targets of the Sendai Seven Campaign over seven years, which are the following: 

• 2016 – Target (a): Substantially reduce global disaster mortality by 2030, aiming to lower the average per 100,000 global mortality rate in the decade 2020- 2030 compared to the period 2005-2015

• 2017 – Target (b): Substantially reduce the number of people affected globally by 2030, aiming to lower the average global figure per 100,000 in the decade 2020- 2030 compared to the period 2005-2015;

• 2018 – Target (c): Reduce direct disaster economic loss in relation to global gross domestic product (GDP) by 2030;

• 2019 – Target (d): Substantially reduce disaster damage to critical infrastructure and disruption of basic services, among them health and educational facilities, including through developing their resilience by 2030;

• 2020 – Target (e): Substantially increase the number of countries with national and local disaster risk reduction strategies by 2020;

• 2021 – Target (f): Substantially enhance international cooperation to developing countries through adequate and sustainable support to complement their national actions for implementation of the present Framework by 2030;

• 2022 – Target (g): Substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments to people by 2030.

Tsunamis are rare events but can be extremely deadly. In the past 100 years, 58 of them have claimed more than 260,000 lives or an average of 4,600 per disaster - more than any other natural hazard.
