Let it flow: Improving water quantity and quality in Tanzania’s Rufiji river basin

Water, essential to all life, plays a particularly important role in the lives of Tanzanians living near Mbarali River, part of the larger Rufiji River basin in southern Tanzania.

Here, farmers use water from the river to irrigate their crops. Cattle herders guide their animals to its banks to drink and graze.  Fishers make a living catching fish from its waters. Still others use it as a place to wash laundry or quench their thirst.  

Yet all of these different demands on the river come at a price.   

“I have a long memory when it comes to this river,” reminisced Alley Mkweta, a longtime resident and local Water Use Association representative. “This used not to be the only river; we used to have several small tributaries, which now only flow during the wet season. 

“I won’t believe anyone who says that this river will never run dry,” he declared, looking around at a gathering of his fellow Water Use Association representatives. “I’ve seen the river drying up too many times before.” 

Indeed, water scarcity has become a pressing problem in the Rufiji basin, raising tensions among the many different people clamouring for access to both its waters and surrounding land. Activities upstream—such as livestock grazing, farming in wetlands or too close to river banks, small-scale irrigation, disposing of waste in the river, and more—have changed the quantity, quality and timing of the river’s flow patterns.  

This uncertainty has caused problems for both upstream and downstream residents. Water Use Association representatives report an increasing number of people falling ill after drinking from the Mbarali River, which they attribute to pollution from human activities in the river catchment. They note that fish are no longer as easily found and worry that plants, animals and their habitats will soon no longer receive the water necessary to sustain them.  

“If this continues,” warned Winfred Mbugu of Sokoine Univeristy of Agriculture, “the amount of water available for each person will continue to drop, and we could arrive at a ‘zero-flow’ situation—meaning the river could dry up entirely.”  

In response, Tanzania’s National Environmental Management Council and Sokoine University of Agriculture will be undertaking a project, set to begin in mid-2020, on assessing the current status and implementing measures to ensure environmental flows remain at recommended levels in the Mbarali River catchment.

Studies and implementation of environmental flows—or  e-flows—are primarily concerned with the fair sharing and sustainable use of water resources. The project proponents will first assess water resource conditions in the Mbarali catchment. Next, they will devise and apply solutions to improve both the quantity and the quality of water supplied by the river.  

The initiative is being funded by the Global Environment Facility through the Implementation of the Strategic Action Programme for the Protection of the Western Indian Ocean from Land-Based Sources and Activities, executed by the Nairobi Convention.

This project aims at reducing land-based stresses on this environment by protecting critical habitats, improving water quality and managing river flows.

The Convention, part of the United Nations Environment Programme’s (UNEP) Regional Seas programme, serves as a platform for governments, civil society and the private sector to work together for the sustainable management and use of the Western Indian Ocean’s marine and coastal environment. 

If successful, the e-flows demonstration project could significantly improve the lives of Tanzanians in the Rufiji catchment. 

The impacts of the project may also be felt far away from Mbarali. As Jerome Ansgary Kayombo of the National Environment Management Council explained, “The project could help us review regulations and laws regarding e-flows.” 

Professor Japhet Kashaigili of Sokoine University of Agriculture agreed, adding that “We are trying to come up with a clear implementation protocol on e-flows—scalable lessons that can be applied one by one to other catchments until the entire country is covered.”

CEOs to G7 and World Leaders: Support “Bold” Net-Zero Commitments

Published

on

Over 70 CEOs said they stand ready to work with public sector leaders around the world to reduce emissions. Members of the Alliance of CEO Climate Leaders signed an Open Letter championing public-private cooperation ahead of the G7 summit in order to supercharge net-zero commitments, polices and actions.

The signatories are looking for governments to accelerate the transition to net-zero before COP26 in order to accelerate even more action from the private sector. The letter emphasizes public-private collaboration as vital and welcomes transformative policy change.

“It is an important and significant move for this many CEOs to put their names forward for deeper collective collaboration,” said Dominic Waughray, Managing Director, World Economic Forum. “It sends a clear signal to policy-makers that many global business leaders are ready to make the transition to a net-zero future. As we move towards COP26, public-private collaboration will be key to unlocking investment, setting more ambitious targets to reduce emissions, and turning this ambition into action.”

The Alliance of CEO Climate Leaders is the only CEO-led community open to all companies worldwide that want to make clear commitments and work to transition to net-zero. Members believe the private sector has a responsibility to actively engage in global efforts to reduce greenhouse gas emissions and to help lead the global transition to a low-carbon, climate-resilient economy. The World Economic Forum hosts the alliance.

The full text of the Open Letter and the list of signatories can be found here on the here on the Forum’s Agenda news site.

Recreate, Re-imagine, Restore!

Published

on

Leaders in global politics, science, communities, religion and culture joined hands today to officially kick off the UN Decade on Ecosystem Restoration – a rallying call for the protection and revival of millions of hectares of ecosystems all around the world for the benefit of people and nature.

Led by the UN Environment Programme (UNEP) and the Food and Agriculture Organization of the UN (FAO), the Decade on Restoration – which runs from 2021 to 2030 – was proclaimed by the United Nations General Assembly in a 2019 resolution.

The launch took the form of a high-level virtual gala with the participation, alongside the heads of UNEP and FAO and UN Secretary-General António Guterres, of Imran Khan, the Prime Minister of Pakistan, which hosts World Environment Day on 5 June this year; Pope Francis; Félix-Antoine Tshisekedi Tshilombo, President of the Democratic Republic of Congo and Chair of the African Union; German Chancellor Angela Merkel; and Prime Minister of Barbados, Mia Mottley. Among the global figures who spoke were UN Messenger of Peace Jane Goodall and other goodwill ambassadors, advocates, youth representatives, scientists and CEOs.

“By restoring ecosystems, we can drive a transformation that will contribute to the achievement of all the Sustainable Development Goals. The task is monumental. We need to replant and protect our forests. We need to clean up our rivers and seas. And we need to green our cities,” the UN Secretary-General said in his message. “Accomplishing these things will not only safeguard the planet’s resources. It will create millions of new jobs by 2030, generate returns of over $7 trillion dollars every year and help eliminate poverty and hunger.”

The FAO Director-General QU Dongyu, noting that the increasing pressure on the world’s natural resources is affecting the well-being of 40 percent of the global population, called for a change of mindset.

“Business as usual is not an option!” he underscored. “We need to prevent, halt and reverse the degradation of ecosystems worldwide, including our farmlands and forests; our rivers and oceans. More efficient, inclusive, resilient and sustainable agri-food systems can help restore ecosystems and safeguard sustainable food production, leaving no one behind,” he added.

“We must use this moment in history to launch a massive global movement to save our terrestrial and marine ecosystems even as we continue to decarbonize. Everyone has a ‘to-do’ here,” said UNEP Executive Director Inger Andersen. “Governments must ensure COVID-19 stimulus packages contribute to a sustainable and equitable recovery from the pandemic. Businesses and the financial sector must reform operations and financial flows so that they restore the natural world. And as individuals and consumers, it is time rethink choices, demand deforestation-free products and vote for sustainability in the polling booths.”

“Restoring the nature we have damaged means, in the first place, restoring ourselves,” said Pope Francis in a video message relayed by Cardinal Pietro Parolin, Secretary of State. “We welcome this United Nations Decade on Ecosystem Restoration, let us be compassionate, creative and courageous. May we take our proper place as a ‘Restoration Generation.’”

The Decade aims to inspire and support governments, multilateral organizations, civil society, private sector companies, youth, women’s groups, indigenous peoples, farmers, local communities and individuals globally, to collaborate, develop and catalyse restoration initiatives across the world. The effort will involve a raft of activities. They range from redirecting fiscal incentives and financial flows to promote restoration to undertaking research on restoration in terrestrial and marine environments, building the technical capacity of restoration practitioners globally and monitoring global progress on restoration.

The Decade aims to mobilize hundreds of millions of people to restore nature and foster a global restoration culture in which restoration initiatives are scaled up across the planet.

“The world has no choice but to go on a nature positive pathway which will not only boost the economy but also protect the environment,“ said Imran Khan, Prime Minister of Pakistan, whose country in 2019 embarked on an ambitious plan to plant 10 billion trees.

Welcoming the launch of the UN Decade, Felix-Antoine Tshisekedi Tshilombo, President of the Democratic Republic of Congo and Chair of the African Union, noted that the African continent had made multiple commitments through several regional Declarations, pledges, Calls to Action and pilot activities, but there was a need to mobilize the necessary resources and expertise to lead large-scale implementation.

“The restoration of terrestrial, marine and freshwater ecosystems should be undertaken in such a way as to avoid creating land conflicts or conflicts of use,” he added. “It must therefore be part of visionary spatial planning processes that take into account inter-sectoral trade-offs, respecting land and resource tenure rights of local communities and other vulnerable social groups.”

In her message, German Chancellor Angela Merkel said: “We have to do more to protect and restore natural habitats – and we have to do it now, not some time in the future.”

“We have to ensure now that forests, which we need not least to regulate our climate, are protected and replenished,” she added.

The Chancellor also announced that Germany would be the first country to provide funding – 14 million Euro – to the Multi-Partner Trust Fund for the Decade on Ecosystem Restoration.

The launch of the Decade on Ecosystem Restoration today leads into World Environment Day on 5 June, the United Nations’ flagship day for promoting worldwide awareness and action for the environment. Held under the theme of ecosystem restoration, this year’s World Environment Day is hosted by Pakistan, which will mark the day and the start of the UN Decade with an event taking place in Islamabad and officiated by Prime Minister Imran Khan with the participation from a host of dignitaries from around the world including UNEP Executive Director Inger Andersen and senior officials from FAO, UN-Habitat and UNDP, as well as senior officials from countries including Germany and Saudi Arabia.

World Environment Day boosts growing global movement to restore damaged ecosystems

Published

on

Individuals, communities, civil society, businesses and governments around the world today marked World Environment Day – with official celebrations held in Islamabad – by making commitments and calling for action to restore millions of hectares of ecosystems all around the world for the benefit of people and nature.

Hosted by Pakistan in partnership with the UN Environment Programme (UNEP), this year’s World Environment Day served as the formal launch of the UN Decade on Ecosystem Restoration (2021-2030). Led by Pakistan’s Prime Minister Imran Khan, speakers at the event – including British Prime Minister Boris Johnson, China’s President Xi Jinping, UN Secretary-General António Guterres, heads of UN agencies and government ministers – stressed the importance of restoration in global efforts to mitigate climate change and promote sustainable development.

“The degradation of the natural world is already undermining the well-being of 3.2 billion people – or 40 per cent of humanity. Luckily, the Earth is resilient. But she needs our help. We still have time to reverse the damage we have done,” the UN Secretary-General said. “That is why, on this World Environment Day, we are launching the United Nations Decade on Ecosystem Restoration. This global movement will bring together governments, businesses, civil society and private citizens in an unprecedented effort to heal the Earth. By restoring ecosystems, we can drive a transformation that will contribute to the achievement of all the Sustainable Development Goals.”

The UN Decade aims to inspire and support governments, UN agencies, civil society, private sector companies, youth, women’s groups, indigenous peoples, farmers, local communities and individuals globally, to collaborate, develop and catalyse restoration initiatives across the world. The Decade aims to mobilize hundreds of millions of people to restore nature and foster a global restoration culture in which restoration initiatives are scaled up across the planet.

“This is an opportunity for the world – these next 10 years, the world has to correct its course. It’s a clash between our greed on the one side and humanity on the other; there needs to be a balance between the two,” said Prime Minister Khan. “When this balance is disturbed and consumerism, consumption and greed reach such a level, this always leads to disastrous consequences for humanity.”

“If we don’t care for our environment, and our ecosystems, it will have severe consequences for the humanity and we will have to pay a big price for this,” he added.

Pakistan has embarked on an ambitious effort to expand and restore its forests as part of its 10 billion-tree drive, recently planting its billionth tree; the country has also pledged to restore about 1 million hectares of degraded lands across the country by 2023 as part of the Bonn Challenge. In addition, Pakistan recently launched its first green bond, seeking $500 million for environmentally friendly projects to enhance the clean energy share in the country’s power sector.

“Restoring ecosystems is a remarkable solution. It slows climate change, brings back lost biodiversity, creates productive land for agriculture, provides jobs and restores nature’s buffers against zoonotic diseases and pandemics,” said Inger Andersen, Executive Director of UNEP.

“If we work hard in four areas – to get finance flows in tune with nature; to protect those that manage land; to make our cities green; and to restore the blue planet – we will heal nature and make everybody’s lives better,” she added.

Other major commitments announced around World Environment Day and the UN Decade include over £8 million in new funding from the UK to protect rare wildlife and vulnerable habitats across the globe; a 8.5 million Euro commitment by Dove and Conservation International to protect and restore 20,000 hectares of forest – the equivalent of 3 million trees – in North Sumatra, Indonesia; a pledge by E.ON, Europe’s largest operator of energy distribution networks, to create biotopes under 13,000 kilometers of high-voltage lines in forest areas; 3 million Euro from Finland to support the launch of, and regional action in developing countries under the UN Decade, and an announcement by Germany that it would be the first country to provide funding – 14 million Euro – to the Multi-Partner Trust Fund for the Decade on Ecosystem Restoration. 

Away from Islamabad, World Environment Day events and initiatives took place across the world, including a virtual concert featuring Patti Smith, the Dave Matthews Band, Michael Stipe and other international artists; the world premiere of Is It Too Much to Ask, a song by DJ Don Diablo for #GenerationRestoration; a virtual Ecosystem Restoration Classroom, a new initiative to take young South African learners – and others – on a journey across three unique landscapes threatened by human development; fireside chats with youth organisations and more.

In collaboration with TikTok, UNEP also challenged users on the content platform to share their ecosystem restoration action using the #GenerationRestoration hashtag. Videos with the hashtag have been viewed over 40 million times, with contributions from influencers including UNEP Goodwill Ambassadors Alex Rendell and Antoinette Taus.

UNEP Goodwill Ambassadors Gisele Bündchen, Formula E driver Lucas De Grassi and Dia Mirza also lent their support to the Day on social media, while young artists such as US poet Jordan Sanchez and Indian sand artist Sudarsan Pattnaik also created imaginative pieces to highlight the urgent need for restoration.
