‘The Shape of Water’, quite symbolically the title of the movie I watched on route to Brasilia for the 8th World Water Forum, reminded me (much like the Avatar movie) about the mystery, strength and silence of nature…and the need for people to speak up for it, so as to protect and preserve it.

That is what the World Water Forum is about. Whilst access to water is a universal human right, without good governance policies, sound scientific research, strong management strategies, and robust legislation, water sources would stand no chance against the planet’s booming population bringing with it increased pollution, abstraction, and artificial alteration of natural flows.

Some may think ‘another conference’, yet I think what could be more important than water to gather a global community of engineers, scientists, policy-makers, heads of state and practitioners around? We all depend on water, there is no viable substitute. Despite many years in the job, I still consider myself privileged to be a part of that community and share in the mindset of finding solutions to the world’s most pressing

From Cape Town to Bangalore, water shortages are a growing global menace, driven by rising demand worldwide and a warming climate. As the search for practical, cost-effective solutions intensifies, we cannot afford to ignore the important contribution nature offers to addressing the global water crisis. This is why the critical role of nature-based solutions is highlighted as the theme of this year’s World Water Day.

Climate change is pushing already overstretched water supplies to the limit. Cape Town’s residents are currently enduring a devastating drought; the 2015 drought in São Paolo forced 9 million Brazilians to ration water. Around the world, one in four of the biggest cities is suffering from water stress.

In fact, water scarcity already affects more than 40% of the global population. According to the UN, our dwindling water resources are increasingly contaminated by pollutants from intensive agriculture, industrial production, mining, urban runoff and wastewater. Meanwhile, our water needs continue to grow, projected to rise by 30% by 2030.

Given the bleak and urgent context, it is not surprising that the global

In the long term, it pays for business to use natural resources in a way that benefits all of society. Efforts to rehabilitate the Rio Doce watershed in Brazil following the 2015 mining disaster are a case in point, writes Yolanda Kakabadse, Chair of the Rio Doce Panel, which will provide advice on the restoration efforts, as the 8th World Water Forum opens in Brasilia this week.

In November 2015, disaster struck near the town of Mariana in Brazil.  The Fundão tailings dam at the Samarco mine failed, spilling water, mud and debris 650km down the Rio Doce, eventually reaching the Atlantic Ocean. The collapse and mudslide killed 19 people, caused severe economic and social damage for communities living along the Rio Doce, and affected fish and other aquatic life. We don’t yet know the full extent of the damage it caused to critical ecosystems and water resources. However, we do know it was one of the country’s worst environmental disasters.

Today, the Rio Doce still carries high levels of sediment from the spill,

In contrast with affluent parts of the world, people living along the White Volta River in northern Ghana seldom take water for granted. Its seasonal flows shape their livelihoods, and their keen appreciation of water-dependent ecosystems is evident in local beliefs and customs. Under traditional land tenure, for example, a “land priest” (or tindana) has responsibility, at least symbolically, for all major decisions about natural resources. Ponds and the surrounding trees – key features of the region’s “natural infrastructure” – are considered to be the abode of ancestors. The “grandmother crocodile pond” in one village is named after a female ancestor of the local chief, who is said to have come back to life in this form.

Valuing natural infrastructure

To the reverential attitudes of rural communities, researchers have added new insights on the benefits that natural infrastructure provides to local communities, which can help guide decisions about natural resource management. This was the focus of a team led by Marloes Mul, a hydrologist with the International Water Management Institute (IWMI), and Laetitia Pettinotti from the Basque Centre for Climate Change (BC3), who recently conducted a study in northern Ghana’s Talensi and West Mamprusi Districts to examine the natural infrastructure that sustains ecosystem services and to characterize the potential impacts on these services of changes occurring in the region. Through a “participatory rural appraisal,” the researchers captured the views of local communities on these issues, taking care to distinguish between the differing perspectives of women and...Read more

It’s no joking matter in Kenya’s Tana River Basin

The authors of a new study about climate change impacts in Kenya have both good news and bad for the country’s vital Tana River Basin. First, the good news: Mean annual rainfall may increase by up to 43% in the course of the 21st century, though with clear differences between rainfall in the upper, middle and lower parts of the basin. And now the bad: Extreme climate events, especially flooding, will also increase. The combined effect of this news will be to make water management in the basin a lot trickier during the decades to come.

Global Landscapes Forum 2017

New findings on the hydrological impacts of climate change in Kenya’s Tana River Basin are being released at the Global Landscapes Forum (GLF) 2017, held in Bonn, Germany, on December 19-20. Efforts to improve water and land management in the Tana Basin are in the spotlight during a GLF session hosted by the CGIAR Research Program on Water, Land and Ecosystems (WLE), along with the International Water Management Institute (IWMI) and International Center for Tropical Agriculture (CIAT).



How Kenya responds to this challenge will make an enormous difference to people and the environment. Consumers in the capital city, Nairobi, get 80% of their water from the Tana Basin. It also delivers 70% of the country’s hydroelectric power and 35% of its total electricity supply. The basin is home...Read more

These are exciting times to be working in Kenya’s water sector. The 2010 Constitution not only enshrines citizen rights to water, but has triggered a raft of reforms aimed at improving public participation and accountability in development processes. As a consequence, substantial responsibilities and funds have been devolved to newly created County Governments, including for water service provision. Local stakeholders are also becoming bolder in challenging top-down water infrastructure developments that could affect their well-being.Read more

As the impacts of climate change become more globally pervasive—and particularly grievous in developing nations—the subsequent need to consider adaptation and resilience objectives within development initiatives is inevitable. Accordingly, in addition to more conventional forms of economic aid, climate finance plays an increasingly important role in supporting the adaptation and mitigation initiatives of developing countries.Read more

The Catamayo-Chira basin straddles the Ecuadorian and Peruvian border in the south of Ecuador. It is one of the 275 transboundary basins in the world. With a population of approximately 280.000 on the Ecuadorian side and 580.000 on the Peruvian side, the basin is of huge importance to the region. The Catamayo-Chira is one of 14 basins in which the IUCN BRIDGE initiative is active. It was the location of a recent BRIDGE meeting field trip as it functions as a good example of the work that BRIDGE does fostering hydrodiplomacy and integrated water resource management across continents.Read more

Large dams contribute significantly to economic growth, food security and national development. They can also help societies cope with climate change by storing water, protecting people and assets from floods, and generating cleaner electricity. Yet, large dams are controversial because of the adverse social and environmental impacts associated with them historically. Among dam proponents, the debate centers on how best to overcome these impacts and how much project financing to set aside for this purpose. Anti-dam campaigners, meanwhile, represent nature as a hapless victim of the tyranny of large infrastructure projects.

Convinced that neither point of view is satisfactory, we propose a more constructive way of thinking. One which acknowledges the dual role that nature plays, contributing to the success of large dams, on the one hand, while helping people adapt to their impacts, on the other.Read more
