Experts share key success factors in reducing vulnerability to drought
Drought is a hazard, but it needn’t be a disaster. That is, provided all communities are adequately equipped before it strikes. At the 10th World Water Forum, held in Bali from 18 to 25 May, experts urged decision-makers to prioritize drought resilience in the face of climate change, drawing inspiration from success cases around the globe.
Representatives from the scientific, non-profit, and technical sectors made the case for building resilience to the world’s costliest and deadliest hazard at an event featuring partners of the International Drought Resilience Alliance (IDRA.) The session took place at the Spanish Pavilion under the auspices of the General Directorate for Water of Spain and the UNCCD.
The experts convened as the need to bridge science and policy for drought risk management is becoming more apparent: global warming is ushering in a new era of rapid-onset, or flash, droughts, just as the global freshwater demand is set to outstrip supply by 40% by 2030, putting societies, economies, and ecosystems on the line.
These are the key takeaways from the conversation:
California to East Africa
“Drought and desertification are not just problems for the Sahel region of Africa and for developing countries,” said UNCCD policy officer Daniel Tsegai before an international audience. “We already see impacts in highly productive and populated parts of the developed world like California, Spain, and Australia.”
In the past two decades, the Colorado river basin (US), which is home to 40 million people, has been experiencing the worst drought in 1,200 years; Australia, has recently grappled with the harshest drought in 800 years; in the Horn of Africa, the worst event in 40 years has left 23 million people severely food-insecure, and Spain has seen the water level of some dams drop to 1% of their capacity.
“The good news is that investments in drought resilience have an up to tenfold return, and we know what it takes to decouple the severity of a drought from its most serious impacts on lives and livelihoods,” explained Tsegai.
Unconventional water resources
For thousands of years, mobile pastoralism has been a prime survival strategy in the Arabian Peninsula, one of the most arid regions in the world. However, urbanization, population growth, and lifestyle changes have brought new challenges —and are spawning new solutions.
“We are looking to expand sewage water treatment and desalination, for example, to irrigate crops, and we are also keen on further building local capacity on sustainable land and water management,” said Omar Ouda, senior water management advisor at the Ministry of Water, Environment and Agriculture of Saudi Arabia. The country will host the largest-ever UN land and drought summit, or UNCCD COP16, from 2-13 December.
Spain, in the Mediterranean basin, has more than 700 desalination plants, including the largest in Europe for drinking water, which is now catering to more than 4.,5 million people in the drought-struck Barcelona area. The amount of energy required to desalinate water, though, remains a key consideration when opting for this tool.
“We make decisions based on indicators like dam water levels,” said water commissioner at the Júcar River Basin Authority in Spain Marc Garcia, who noted the importance of adopting a proactive approach to drought management. “On the basis of such information, authorities assess options like intensifying desalination, decommissioning wells and, if necessary, restricting water use in certain basins.”
Nature-based solutions
While technology and grey infrastructure can contribute to building resilience, nature-based solutions and sustainable land and water management remain central to mitigating, and adapting to, future droughts, according to several panellists.
Land degradation, for example, disrupts regional rainfall patterns by disrupting the amount of water that regularly moves from the earth to the air. Conversely, healthy lands support consistent seasonal and annual rainfall; facilitate aquifer recharge; and mitigate the risk of droughts and floods.
“Nature can be a big part of the solution,” said the Director of Water Scarcity and Markets at The Nature Conservancy (TNC) Tom Iseman. “For instance, it is essential we protect source watersheds, keeping their storage capacity intact, slowing runoff, and protecting water quality,” said the expert of TNC, which is engaged in source water protection initiatives across Africa.
Success factors for water governance
The International Water Management Institute (IWMI) is helping communities conserve and use water more efficiently, based on the latest scientific insights and innovations —from drought-tolerant seeds and improved irrigation methods to remote sensing technologies to explore new water resources. They also support policy-makers in creating drought policies across Africa and Asia.
“To define drought policies, it ideally needs to be raining outside because it takes time to put them together,” said IWMI deputy director general Rachael McDonnell, and explained they involve the ministries of health, environment, agriculture, economy, infrastructure, and finance, as well as statistical and meteorological agencies.
The process must engage all governance levels, from national institutions to local administrations and communities, she said, and make sure crucial data is available to all of them —a consideration they keep front and centre as they support the creation of early warning systems in countries like Zambia, Morocco, Jordan, and Lebanon.
For director general of the US National Drought Mitigation Centre at the University of Nebraska, Mark Svoboda, another key is involving users in the co-design of information systems and tools to build ownership in the long run.
From his experience in southern Africa, countries that successfully appropriate and put to use drought early warning systems create a ripple effect.
“They generate positive peer pressure: neighboring countries want to understand how to do what they do, so building trust now takes one year, instead of eight,” said Svoboda. “It all starts with political will, and showing tangible results is the best way to get buy-in from decision-makers.”
Drought communications
In the lead up to major international events like UNCCD COP16 and Drought+10, participants called on the Alliance to get the word out on the urgency of building drought resilience.
“Drought is a major threat multiplier, but it is too often lost to audiences, overshadowed by geopolitics and other conflicts,” said McDonnell from IWMI.
Executive secretary and CEO of the Global Water Partnership (GWP) Alan AtKisson echoed the need to boost communications on drought at all levels, from the public and affected communities to political leaders and the finance sector:
“We need to talk much more about drought resilience, and we need investors to understand how drought can impact their value chains going forward,” said AtKisson. “Tropical storms get the headlines, but the hazard that destroys most economic value on our planet is drought.”
