Five solutions for drought resilience from World Water Week 2025

In the past decade, the world has made a historic push to prepare for drought before it strikes, unlocking solutions in policy, practice, and finance. Humanity has never been better equipped to face this growing challenge. 

The next step, experts say, is using all the available knowledge and expertise to build drought resilience for everyone, everywhere. At World Water Week, held in Stockholm from 24 to 28 August 2025, The Nature Conservancy (TNC), the German Agency for International Cooperation (GIZ), and the UN Convention to Combat Desertification (UNCCD), co-convened leading experts to highlight success cases and new initiatives for drought resilience.

Here are five takeaways from the session ‘Accelerating Drought Resilience in a Changing Climate:’

Systemic measures for a systemic risk

Far from only affecting agriculture, drought can have long-lasting impacts on all sectors of society, the economy and ecosystems - uprooting people from their lands, stunting the development of entire generations, and causing GDPs to plummet by up to 10 per cent. 

Drought is a systemic risk, but too often, it is addressed with piecemeal measures. “Water crosses so many boundaries as it moves from the tops of mountains through ecosystems towards the ocean: administrative, legal, cultural, ecological boundaries,” said Global Director of Freshwater Outcomes at TNC Nicole Silk. “That is why we need to work across systems, sectors, borders, and scales to build drought resilience”.

In that spirit, the nonprofit is supporting the implementation of nature-based solutions across entire watersheds in collaboration with communities, the private sector, and governments. Protecting key ecological functions is a nature-based solution, as are financial innovations.

One example is TNC's work in the Tana River in Kenya, which supplies 95 per cent of the water for Nairobi’s 4 million residents, feeds one of the country’s main agricultural areas, and provides half of the country’s hydropower output. In the past 50 years, the substitution of agricultural fields for forests and wetlands had reduced the ability of the land to store runoff water and hold the soil, compromising the water security of millions.

Enter the Upper Tana-Nairobi Water Fund. The mechanism, which TNC kickstarted in 2015 as is now an independent Kenyan-registered entity, has public and private donors and major water consumers downstream contribute resources to support water and soil conservation measures upstream, which is improving water quality and supply.

No-regret investments

Protecting ecosystems, managing land and water resources sustainably, and restoring degraded land are some of the most effective and sustainable ways of building drought resilience. But the benefits of nature-based solutions go way beyond drought.

Every dollar invested in nature-based solutions (NbS) can generate up to USD 27 in improved ecosystem services and livelihoods - a no-regret investment, according to a recent report launched at UNCCD COP16 and as evidenced by the Economics of Land Degradation (ELD) Initiative.

“More intense and frequent droughts are the new normal,” said Senior Policy Officer at BMZ Mario Lootz-Petersen. “Our goal is to make nature-based solutions a new normal, as well. The evidence and the tools are definitely there.” 

For the expert, one of the keys is continuing to build robust business cases and models around sustainable land and water management with a view to scaling up the many successful initiatives around the world.

Tailored approaches 

While the pillars of drought resilience are universal, each context requires its own tailored solutions. Hence the importance of adapting drought resilience approaches to different realities.

“A key question is how we can localise drought resilience solutions such as climate-smart agriculture, drought insurance, and water-storage innovation,” said Giriraj Amarnath, Principal Researcher on Disaster Risk Management and Climate Resilience at the International Water Management Institute (IWMI).

Through the Drought Action Catalyst, experts, decision-makers, and communities can come together to co-design and scale solutions for drought. The IWMI-led platform, launched at UNCCD COP16, also promotes South-South learning; an integrated action across sectors like agriculture, health, and infrastructure, and even an AI-based chatbot to help farmers tackle drought.

From policies to practice 

With support from UNCCD, more than 70 countries have put in place national plans to manage drought risk, up from three only a decade ago. In parallel, the convention is hosting two major initiatives on drought resilience and is collaborating with academic, research and civil society organizations to bridge policy and practice.

One of the UNCCD-hosted initiatives is the International Drought Resilience Alliance (IDRA), which is building political momentum and developing tools to help countries anticipate, prepare for, and adapt to drought - for example, the International Drought Resilience Observatory (IDRO). 

The other is the Riyadh Drought Resilience Partnership (RDRP), which will financially support 74 vulnerable countries in implementing their national drought plans from early 2026, as explained by Policy Officer with the UNCCD Daniel Tsegai. The idea is to invest in people, land, and ecosystems today, so that communities can thrive tomorrow.

Additionally, the Convention and the Global Water Partnership (GWP) have launched a series of regional and global  Communities of Learning and Practice (CLP) - an agora where practitioners, decision-makers and scientists can learn from each other, ask for advice, and share new developments on drought-related matters.

“I cannot overstate how important peer-to-peer learning is when it comes to accelerating drought action on the ground,” said Tsegai, who stressed the importance of sustainable land and water management. “Together, we can go further, faster - and the CLPs provide a safe space to do just that.”

Beyond early warning

In Africa, UNCCD teamed up with the Sahara and Sahel Observatory (OSS) - an IDRA partner - and the National Drought Mitigation Center/ University of Nebraska-Lincoln (NDMC/UNL) to create a drought impact tracker for countries in the region. The tool looks to empower farmers to report on drought signs and impacts using their phones, contributing to improve drought management.

A project led by the GWP is now integrating the impact tracker into efforts to improve early warning systems in Eastern Africa. For GWP specialist Anjali Lohani, the move shows the importance of integrating existing tools and insights, instead of trying to reinvent the wheel.

“So much knowledge already exists, so a priority is to make it available and accessible to those who need it,” said Lohani, who also noted the importance of building the capacity of communities to act on early warning messages. “Knowing that drought is coming is not enough; you need to have preparedness and response capabilities in place.”
