Washington Most of the world is unprepared for floods, hurricanes and droughts, which are expected to be intensified by climate change, and an urgent need for better warning systems to avoid water-related disasters, according to a United Nations Meteorological report Is. agency. It is called.
Global water management is “fragmented and inadequate,” according to a report released Tuesday, with nearly 60% of the 101 countries surveyed have an improved forecasting system to help prevent the devastation of stormy weather. needed.
The report said that as the population grows, the number of people with inadequate access to water is expected to exceed 3.6 billion in 2018, rising to 5 billion by 2050.
For example, the actions suggested in the report were better warning systems for flood and drought-prone areas that could recognize when rivers were likely to be in spate. There is also a need for better funding and coordination between countries on water management, according to reports from the United Nations World Meteorological Organization, development organizations and other groups.
“We need to wake up to the impending water crisis,” said Petri Taras, secretary general of the World Meteorological Organization.
According to the report, since 2000, flood-related disasters have increased by 134% globally compared to the previous two decades. Most of the flood-related deaths and economic losses have occurred in Asia, and over the past year, excessive rainfall has caused major flooding in China, India, Indonesia, Japan, Nepal and Pakistan.
The frequency of drought-related disasters increased by 29% over the same period. African countries recorded the most drought-related deaths. According to the report, the most severe economic losses from drought occurred in North America, Asia and the Caribbean.
Globally, the report found that 25% of all cities were already facing regular water shortages. Over the past 20 years, the total supply of water in surface water, groundwater, soil, snow and ice has declined by 0.4 inches (1 centimeter) annually.
Elfati Eltahil, a professor of hydrology and climate at the Massachusetts Institute of Technology and who was not involved in the report, said population growth would further impact water supplies, especially in sub-Saharan Africa.
“As the population increases, the availability of water becomes a place where water adaptation becomes very important,” he said.
Despite recent developments, the report found that 107 countries will not meet the goal of sustainable management of water supply and access by 2030 at current rates.
