The Global Goals: How on Earth can geologists make a difference?

On the 30th October the Bristol Geology for Global Development (GfGD) group trekked off to London to the grandeur of the Geological Society for the 3rd annual GfGD conference. Joel Gill, the director of GfGD, opened the conference with the bold claim: “Probably the world’s first meeting of geologists to discuss the Global Goals.” And it’s not an overstatement. Despite first appearances, geology has a crucially important role to play in many of the 17 goals internationally agreedby World Leaders in September this year. So why aren’t we talking about it? The conference acted as a platform for these discussions, it gave geologists a chance to learn how they can actually contribute to the success of these international development targets and it introduced us to new ways in which geology can help make a difference.

Soils and cities


Two scientists from the British Geological Survey touched on some particularly interesting examples of unlikely connections with geology and development.

We heard from Dr Michael Watts about how soil geochemistry is being used to maximise the potential to grow nutrient rich crops in places where people lack vital nutrients in their diets. In many areas of Malawi, people are suffering from selenium deficiency, which can cause a weakened immune system and an underactive thyroid. By increasing the alkalinity of the soil it may be possible to increase the amount of selenium in the plants that grow in that soil.

In a world that is becoming increasingly urbanised, Dr Katherine Royse stressed the importance of consulting geologists in urban developments. The subsurface is a finite resource and is being utilised in every possible way beneath cities, for transport, water works, electricity distribution and much more. In London, many infrastructure and building projects end up costing 50% more because developers weren’t aware of subsurface conditions from the outset.

These examples highlight the necessity for geologists to be included in discussions about health, about sustainable cities and about many other Global Goal themes. Geologists have much to bring to the table.

What did you say?


Of course, a big focus of the GfGD conference was about how we can communicate our science to people with no scientific background. If we want to use geology to help better prepare people for natural disasters, or to help make communities more resilient to climate change, explaining simple geological processes in a way that people understand is absolutely key. And often we need to take a step back to get exactly what angle the person we’re communicating to is coming from.

One particularly striking example of communication was introduced by Solmaz Mohadjer and related to children in Tajikistan who wondered why earthquakes were happening to them. Earthquakes happen all over the world and that seems obvious to us, but it’s not necessarily obvious to everyone. These children came up with all sorts of explanations for the earthquakes they were experiencing including that the Earth was balanced on a tower of elephants!

Through educational tools that the children, teachers and teacher trainers can understand, everyone can learn why earthquakes happen and how they can best protect themselves from them.

But we also need to remember we can’t just march in with all the answers. Jonathan Stone from TearFund encouraged us to be aware of what it is that makes someone an expert. The expert isn’t the person who comes along with the scientific explanation, ‘letting knowledge out like a dam’, the new expert is the person who encourages and inspires others to act for themselves.

Inspiring a new generation of geologists

Many Bristol GfGD members who came to the conference didn’t really know what to expect and went away with new perspectives on their subject. With ideas of how geology fits into all sorts of careers, not just the usual oil and mining sector. And with a view of how geology is one cog in the giant machine that is trying to tackle many of the world’s problems through the Global Goals.

The part of the conference that our group found most poignant were the views of early career geologists on how sustainability is integral to their job. In particular, we heard an account from exploration geologist, Sarah Craven, who was calling for people to become ambassadors for sustainability within the mining industry or indeed whichever sector they choose to go into.

Creating a generation of geologists who are mindful of their impact and who are aware of how they can use their skills to positively contribute to international development is at the heart of GfGD.

We lingered at the end of the conference, still in awe of our surroundings at the Geological Society. The buzz in the room was a tell tale sign that the 3rd Annual conference had achieved what it set out to do. Posing questions about how geology fits into the Global Goals, showing us what great work geologists are already doing and inspiring us to go after these opportunities ourselves. Let’s hope when the outcomes of the Global Goals are reviewed in 2030 that we’ll be able to say, “geologists helped to make that happen!”

Converting probabilities between time-intervals

This is the first in an irregular sequence of snippets about some of the slightly more technical aspects of uncertainty and risk assessment.  If you have a slightly more technical question, then please email me and I will try to answer it with a snippet. Suppose that an event has a probability of 0.015 (or 1.5%) of happening at least once in the next five years. Then the probability of the event happening at least once in the next year is 0.015 / 5 = 0.003 (or 0.3%), and the probability of it happening at least once in the next 20 years is 0.015 * 4 = 0.06 (or 6%). Here is the rule for scaling probabilities to different time intervals: if both probabilities (the original one and the new one) are no larger than 0.1 (or 10%), then simply multiply the original probability by the ratio of the new time-interval to the original time-interval, to find the new probability. This rule is an approximation which breaks down if either of the probabilities is greater than 0.1. For example

1-in-200 year events

You often read or hear references to the ‘1-in-200 year event’, or ‘200-year event’, or ‘event with a return period of 200 years’. Other popular horizons are 1-in-30 years and 1-in-10,000 years. This term applies to hazards which can occur over a range of magnitudes, like volcanic eruptions, earthquakes, tsunamis, space weather, and various hydro-meteorological hazards like floods, storms, hot or cold spells, and droughts. ‘1-in-200 years’ refers to a particular magnitude. In floods this might be represented as a contour on a map, showing an area that is inundated. If this contour is labelled as ‘1-in-200 years’ this means that the current rate of floods at least as large as this is 1/200 /yr, or 0.005 /yr. So if your house is inside the contour, there is currently a 0.005 (0.5%) chance of being flooded in the next year, and a 0.025 (2.5%) chance of being flooded in the next five years. The general definition is this: ‘1-in-200 year magnitude is x’ = ‘the current rate for eve

Coconuts and climate change

Before pursuing an MSc in Climate Change Science and Policy at the University of Bristol, I completed my undergraduate studies in Environmental Science at the University of Colombo, Sri Lanka. During my final year I carried out a research project that explored the impact of extreme weather events on coconut productivity across the three climatic zones of Sri Lanka. A few months ago, I managed to get a paper published and I thought it would be a good idea to share my findings on this platform. Climate change and crop productivity  There has been a growing concern about the impact of extreme weather events on crop production across the globe, Sri Lanka being no exception. Coconut is becoming a rare commodity in the country, due to several reasons including the changing climate. The price hike in coconuts over the last few years is a good indication of how climate change is affecting coconut productivity across the country. Most coconut trees are no longer bearing fruits and thos
