This Country Is Running Out of Water Amid Historic Drought

Popular

By Jan Rocha

The government of Bolivia, a landlocked country in the heart of South America, has been forced to declare a state of emergency as it faces its worst drought in at least 25 years.

Much of the water supply to La Paz, the highest capital city in the world, and the neighboring El Alto, Bolivia's second largest city, comes from the glaciers in the surrounding Andean mountains.

But the glaciers are now shrinking rapidly, illustrating how climate change is already affecting one of the poorest countries in Latin America.

The three main dams that supply La Paz and El Alto are no longer fed by runoff from glaciers and have almost run dry. Water rationing has been introduced in La Paz, and the poor of El Alto—where many are not yet even connected to the mains water supply—have staged protests.

The armed forces are being brought in to distribute water to the cities, emergency wells are being drilled and schools will have to close two weeks ahead of the summer break

President Evo Morales sacked the head of the water company for not warning him earlier of the dangerous situation, but the changes produced by global warming have been evident for some time.

Shrinking Snowline

A recent report by the Stockholm Environment Institute (SEI) says:

"Temperatures in the region have risen by 0.5°C in the period 1976 to 2006, and the people of La Paz and El Alto can observe evidence of climate change in the form of the shrinking snowline in the mountains above them.

"One glacier on Chacaltaya mountain—which rises above El Alto and which once hosted the world's highest ski resort—has already completely disappeared. And the two Tuni-Condoriri glaciers that provide water for El Alto and La Paz lost 39 percent of their area between 1983 and 2006—at a rate of 0.24 sq km per year."

The SEI said that if the regional and global climate models that predict a two-degree rise in temperatures by 2050 are right, many small glaciers will completely disappear, while others will shrink dramatically. It warns:

"Glaciers are estimated to provide 20-28 percent of water for El Alto and La Paz. Therefore, glacier loss will have a considerable impact, which will be felt particularly during the dry season, when glacial water provides the majority of urban water.

"The glaciers and mountain water systems also support agriculture, power generation and natural ecosystems throughout the region."

The problem is exacerbated in El Alto, a sprawling settlement of over a million people who have migrated from the countryside.

The city's population grew by at least 30 percent between 2001 and 2012, and the city's land area has rapidly expanded by 144 percent in the last decade, spreading into the flat open countryside to the south and west. By 2050, the population is expected to double to two million people.

The SEI believes that one of the causes of this increased influx into the city will be climate change.

It said:

"Evidence from El Alto's history indicates that the fastest periods of population growth coincided with droughts, floods and bad harvests associated with the meteorological phenomena of El Niño and La Niña.

"The years 1985-1987, when migration into El Alto reached heights of 65,000 new immigrants, were also years of poor harvests."

Supply Outstripped

By 2009, demand for water in El Alto had already outstripped supply, and that supply is now increasingly under threat as climate change melts the glaciers.

Bolivia cannot rely on new sources to resolve its water crisis, given both the costs and potential range of climate change impacts. So one of the country's most critical challenges in coming years will be to plan and implement strategies for managing water under uncertain climate conditions.

Conservation and recycling methods, the SEI said, will be needed to build the resilience of Bolivian cities' water systems to climate change.

The cities will also need to find ways of reducing water consumption, especially from industries and commercial enterprises, but also from the profligacy of a small number of rich domestic consumers.

The SEI paper recommends community participation in developing strategies and decision-making on the management of water resources. But, at the moment, the only role for those affected communities is that of protest.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.

The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.

Ocean scientists have been busy creating a global network to understand and measure changes in ocean life. The system will aggregate data from the oceans, climate and human activity to better inform sustainable marine management practices.

EcoWatch sat down with some of the scientists spearheading the collaboration to learn more.
