Water and Sustainable Development – 6th GfGD Annual Conference Event Report

Water and Sustainable Development – 6th GfGD Annual Conference Event Report

Understanding, managing and protecting water resources is critical to the delivery of the UN Sustainable Development Goals (e.g., education, water and sanitation, healthy oceans, zero hunger, good health, gender equality, energy, industry, and biodiversity). Increasing urbanisation, industrialisation, and climate change, however, are increasing pressure on water supplies and reducing water quality. Our 6th Annual Conference explored the role of geoscientists in managing conflicting demands for water, ensuring that the needs of the poorest are met while enhancing the health of ecosystems. We recently published a full event report online, and here we share some of the highlights.

Our Annual Conference is a highlight for many involved in the work of Geology for Global Development, bringing together people from across the UK and beyond to explore how geoscientists can contribute to sustainable development. This year approximately 120 attendees gathered at the Geological Society of London to talk about all things water, Sustainable Development Goals and geoscience.

The conference was opened by Lord Duncan of Springbank (UK Government Minister for Scotland and Northern Ireland, and a fellow geoscientist). Lord Duncan gave a passionate description of the important links between politics, geology and sustainable development. Another distinguished guest was Benedicto Hosea, visiting the UK from Tanzania and working closely with the Tanzania Development Trust. Benedicto gave us an insight into water resources in Tanzania, and the realities of implementing projects and taking practical action to improve water provision.

Our keynote lecture was delivered by Professor Bob Kalin from the University of Strathclyde, who gave us an overview of the interactions between water, geoscience and human impacts – and why it is important that geoscientists engage in the delivery of the Sustainable Development Goals. You can find a recording of a similar talk Professor Kalin presented at a TedX event.

The first panel discussion of the day focused on management, with insight from industry, academia and the Overseas Development Institute. We discussed the challenges involved in listening to and considering many stakeholders, the management of transnational aquifers and how best to enforce policy – then attempted to come with some solutions to these challenges. Our event report includes links to key reading suggested by our panellists.

Water contamination is a significant environmental issue in many countries at all stages of development.  We heard about research into salinization and arsenic contamination of groundwater in Bangladesh. Mike Webster, head of WasteAid (check them out here) gave a different perspective on water contamination, talking about the work the charity has done in improving solid waste collection, thereby improving drainage and water quality.

Probably the most hectic, yet fun part of the conference was the UN style activity – we split up into groups representing different stakeholders and came up with a research and innovation statement relating to water and the SDGs.

We were also joined by The Eleanor Foundation, a charity working in Tanzania to provide access to safe, clean water provision to communities through pump installation and education programmes. It was so inspiring to hear about a charity that has undertaken effective work in ensuring the sustainable supply of water to communities, and made a real difference in improving lives – it is estimated that the Eleanor Foundation has improved access to water to over 250,000 people. In 2019, GfGD will be supporting the work of The Eleanor Foundation, helping to deliver SDG 6 in Tanzania. We will be using surplus income from our conference, together with other funds, to facilitate an evaluation of The Eleanor Foundation’s water programme. This will generate recommendations for The Eleanor Foundation team to ensure long-term impact and sustainability.

In true GSL conference style, we finished the conference with a reception in the library, giving us all the chance to chat about the conference and meet people sharing an interest in geoscience and development (of course admiring William Smith’s geological map!). I think it would be fair to say that a fun and interesting day was had by all, and I left feeling excited by the number of geoscientists I met that all share enthusiasm for the role that geoscientists have in helping to achieve the SDGs.

The 7th GfGD Annual Conference will be on Friday 15th November 2019, hosted again by the Geological Society of London. Please do save the date, and we hope to see you there!

What is happening after the Fuego eruption in Guatemala? Is climate migration a bad thing? This and more in Jesse Zondervan’s June 2018 #GfGDpicks #SciComm

Each month, Jesse Zondervan picks his favourite posts from geoscience and development blogs/news which cover the geology for global development interest. Here’s a round-up of Jesse’s selections for the last month:

Everything about the Fuego eruption

At the start of this month, Guatemala’s Fuego volcano erupted explosively, costing many lives and destroying properties and infrastructure.

Professor Handley from Macquarie University explains why the eruption was so disastrous, while Professor Little notes the recovery efforts Guatemalans make on their own, without much government input. Sophie Brockmann delves into history and recovers the cultural significance and political intricacies of Guatemalan dealings with volcanoes.

Climate migration: is it a bad thing?

While the world wakes up to the magnitude of climate migration, a key question we will need to ask is: does climate migration pose a problem or an opportunity to climate adaptation? As always, knowledge is power: a team of New York scientists has modelled future migration due to sea level rise in Bangladesh.

Drought: South Africa out, India in

Drought seems to be a trendy topic this month. South Africa has moved out of the national state of drought disaster and is moving on to resilience. At the same time, India is approaching a long term water crisis and a map of desertification by the EU Joint Research Centre shows building pressures on the world’s resources.

Somewhat reassuring is the opportunity for mitigation that MIT researchers give us. They conclude that climate action can limit Asia’s growing water shortages.

This month a lot was written on climate change adaptation, but as well as disaster risk reduction and sustainability. I would like to highlight this one question: What’s the right goal – resilience, well-being or transformation?

Demonstrating the Importance of Geoscience in the Transformation Towards Sustainable and Resilient Societies

Next week the UN Annual Forum on Science, Technology and Innovation for the Sustainable Development Goals (SDGs) will discuss the science required for “transformation towards sustainable and resilient societies”. Discussions will focus on SDGs 6 (water and sanitation), 7 (energy), 11 (sustainable cities), 12 (responsible consumption and production) and 15 (life on land).  

This forum will bring together member states, civil society, the private sector, the scientific community, and United Nations entities. It aims to facilitate interactions, networks and partnerships to identify and examine needs and gaps in technologies, scientific cooperation, innovation and capacity-building to support the SDGs. We believe it is critical that the global geoscience community is represented, and will therefore attend and ensure a clear voice for geoscience at the heart of global development decision-making.

The natural environment is a key pillar of sustainable development. Research, innovation and improved communication and use of geological science (or ‘geoscience’) is therefore essential to delivering sustainable and resilient societies. For example,

  • Mapping and Understanding the Sub-Surface. In a sustainable and resilient society, interactions between the surface and sub-surface are understood and integrated into urban planning to ensure that development is safe, hazards are mitigated against, and environmental impact is minimised. Geological maps, geophysical surveys, and the integration of geoscience data to develop ground models can generate an understanding of the sub-surface and support effective urban planning.
  • Resource Management. In a sustainable and resilient society, everyone has sufficient and reliable access to energy, clean water, and the materials required for sustainable, resilient cities. This requires the identification and careful management of natural resources, including water, minerals, and building aggregates. The transition to renewable energies, such as solar panels and wind turbines, and electric transport will require a wide range of minerals, such as cadmium, lithium, molybdenum, selenium, and tellurium, as well as rare earth elements.
  • Waste Management. In a sustainable and resilient society, less pollutants are generated, and those that are generated are better managed to reduce the environmental impact of society. Pollutants can take many forms, and these can impact both the surface and sub-surface. For example, while mining may be necessary to supply the materials needed for green technologies, this can generate large amounts of waste which needs to be managed carefully to avoid chemicals leaching into groundwater.
  • Reducing Disaster Risk. In a sustainable and resilient society, the focus is on reducing risk (and preventing disasters), rather than accepting or increasing risk (and responding to disasters). Resilient communities, water supplies, energy infrastructure, and terrestrial ecosystems require effective disaster risk reduction. Research on the processes and potential impacts of earthquakes, volcanic eruptions, tsunamis, landslides, subsidence, and other geological hazards can help stakeholders to understand and reduce risk.

Sustainable and resilient societies, therefore, depend on access to geoscience information and the expertise to interpret this, as well as meaningful engagement by the geoscience community. The networks and partnerships being developed at the UN next week, to identify how scientific cooperation and innovation can support the SDGs, need to include geoscientists working across a broad array of specialisms.

Since the SDGs were agreed in 2015, we have been at the forefront of mobilising and equipping the geological science community to engage and help deliver this vision. We are proud to continue our international leadership on this topic, and will be a champion of the geosciences next week at the UN Headquarters.

Heather Britton: China’s Water Diversion Project

Heather Britton: China’s Water Diversion Project

China has enjoyed economic growth over the past decades, bringing undoubted prosperity to the country. But exponential industrialisation and rapid growth comes at a significant environmental cost. The nation is heavily dependent on coal-fired power, making it one of the world’s largest emitters of greenhouse gases and it’s thirst for development is a drain on vital resources, including water. In today’s post, Heather explores how China’s geography accentuates an anthropogenic problem. 

When travelling from the North to the South of China there are number of trends that can be observed – dialects change, the dominance of noodles is replaced with a preference for rice and, crucially, the climate becomes more humid. The South typically receives excessive rainfall, often leading to devastating flooding, whilst the North dries due to the thirst of industry and a booming population. China’s water diversion project aims to solve both problems with one monumental feat of engineering – by diverting 44.8 billion cubic metres of water annually from South to North via a network of canals and tunnels. I’ll explore the impact that this is having on China and its people, and whether it is a sustainable solution to the disparity in water supply across the country.

Water shortage is a constant concern in the North, with the groundwater stores that support the region dwindling to a fraction of what is required to allow the cities and industries centred here to thrive. In addition, more than half of China’s 50,000 rivers have disappeared in the last 20 years. Having experienced unprecedented economic growth over the past few decades, Beijing is on the brink of a water crisis. In the South, flooding is the primary hydrological issue, exacerbated by the drainage of lakes and the damming of rivers for construction. It was commented in the 1950s by Chairman Mao that ‘The south has plenty of water, but the north is dry. If we could borrow some, that would be good’. This statement is heralded as the idea that has grown to become what is now ‘The world’s most ambitious water-transfer program’.

The project is not merely a fantasy – construction on a number of the pathways is already complete or nearing completion, and already over 70% of Beijing’s water is transferred from the South as a result of this project. Costing $62 billion, there is a clear driving force for the project – the thirsty North is running out of water fast, and although an extreme move, it is true that this project will provide some vestige of relief – but for how long, and at what cost?

Millions have benefitted from the water transfer and it certainly is a solution to the disparity in water supply between the North and the South of the country, but it is also arguably one of the worst. China’s demand for water is growing so quickly that even before the project’s completion in 2050 further solutions are likely to be required, and industrialisation along diversion routes poses a serious pollution threat. Salinization  of some waters heading North seems inevitable. An even larger concern is that the South may no longer have enough water to spare – the Han river, an important tributary to the Yangtze, is planned to have 40% of its water diverted to the North, but the towns and cities situated along its course are already experiencing water shortages. Furthermore, 345,000 villagers have been displaced from their homes to make way for the new water courses, often to lands and property far inferior to what they were promised and what they left behind. It is clear that the project is far from sustainable.

It would be wrong, however, to say that the Chinese government is doing nothing to reduce the impact of the scheme. Addressing environmental concerns in the Danjiangkou reservoir, a $3 billion ecological remediation package has been put together, and the water diversion project has allowed the groundwater reservoirs in Beijing to rebound by at least 0.52m. The environmental threat persists, however, and it seems unlikely that retrospective measures will be able to dissipate all of the environmental risk. By considering more sustainable solutions, the impact on the land and the people of China could have been drastically reduced. The Chinese vice minister of Housing and Urban-rural development has called the project unsustainable, acknowledging that, in the case of many cities, recycled water could replace diverted water. If efforts were focussed on water desalination technology and the collection of more rainwater, rather than the creation of multiple colossal aqueducts with unsavoury environmental consequences, then water resource management could be tackled in a far more sustainable manner.

Effective water conservation is something that is becoming a larger and larger problem for the Global South, particularly in the drier parts of the world. The water diversion project acts as an interesting case study, and shows the repercussions of dramatic engineering solutions to water resource problems. Although possible from an engineering perspective, forcing a change in the hydrological system of a country is rarely without its complications (and substantial expense). Lessons can be learned from the water diversion project, and future Global South nations should think twice before entering into any project of such scale without considering the full implications or other, more sustainable options. Doing this would help towards the achievement of UN Sustainable Development Goals 11 (sustainable cities and communities) and 6 (clean water and sanitation).
