When are Californian earthquakes coming back with vengeance? How does climate-change-induced flooding increase inequality? Lessons from Cyclone Idai; that and more in Jesse Zondervan’s April 2019 #GfGDpicks #SciComm

Aftermath damage of the San Francisco earthquake of 1906

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:

California seems to be overdue for earthquakes, meaning there has been a so-called earthquake ‘drought’ in the last century. Paleoseismic studies show that this hiatus is unprecedented in the last ten centuries. This means we might see a high frequency of earthquakes coming this century, while a generation who hasn’t experienced any major earthquake has passed.

Furthermore, a related article in the San Francisco Chronicle reports the US Geological Survey projects a major quake along the San Andreas Fault would cause more than 98 billion in building damage and kill up to 7,800 people. The main threat, however, is the aftermath with loss of power for at least three days and half of households without water for at least a month. The study highlights the importance of preparing the population for a quake and its aftermath.

Fortunately, this month also saw the publication of a Californian record of two million tiny earthquakes detected by Caltech scientists. This tenfold increase in the earthquake catalogue tells them more about how faults and earthquakes work and get triggered. Greg Beroza, a Stanford University seismologist says “It’s just like if a new telescope comes along and its magnification is 10 times greater”.

Can climate-change induced flooding increase inequality?

The answer seems to be yes, in fact it does. A report published by the Urban Institute in the US showed that people with poor credit scores suffered bigger drops in scores than those starting with high scores. While home-owners receive insurance pay-outs, costs to renters only increase due to increased demand after major storms.

Similarly the New York City Panel on Climate Change reports climate change is affecting everyday life in New York today, and will hit the poorest neighbourhoods in the future.

Consequently, social vulnerability should be considered when risk is modelled and funding allocated, according to RMS flood specialist Nicole Howe.

 

More perspectives this month on the aftermath and lessons from Cyclone Idai which struck southern Africa in March; the challenge of religious resignation to building resilience against natural hazards in Indonesia and what the new bill on the US National Volcano Warning System means to disaster risk reduction.

The ethical questions behind the school climate strike. Do we have a place in earth’s ecosystems? Jesse Zondervan’s February 2019 #GfGDpicks #SciComm

The ethical questions behind the school climate strike. Do we have a place in earth’s ecosystems? Jesse Zondervan’s February 2019 #GfGDpicks #SciComm

Each month, Jesse Zondervan picks his favourite posts from geoscience and development blogs/news which cover the geology for global development interest. This month’s picks include: The ethical questions behind the school climate strike; Military worries about the fight against sea-level rise – how will you help? Do we have a place in earth’s ecosystems?

School climate strikes

As school climate strikes inspired by Greta Thunberg spread across the world in the past month, adults are starting to ask ethical questions.

If one would prefer climate activism to focus on conventional electoral politics, rather than civil disobedience, Rupert Read argues one should question the premise that our societies are fully democratic. If adults have failed, how can we support and listen to our children rather than telling them what to do?

The idea that young people are the key to making positive change to the way we live in our environment is not a new one, but did you ever wonder why? Steve Cohen at Columbia University’s Earth Institute considers how the experiences of the next generation support a survivalist ethic and a change in environmental politics.

The fight against sea-level rise

If the urgency displayed by our children leaves you hungry to roll up your own sleeves, paradoxically it may appear you could help by joining the army to help fight sea-level rise. At a conference on climate change and security at The Hague defence leaders from around the world expressed worry not only for a risk for conflict risks but also of stress on military capacity in all countries with a coastline, not just the poorer nations.

Alternatively, if you have a more entrepreneurial spirit, I would recommend looking at entrepreneurial opportunities for addressing climate change in the developing world.

Sea-level rise and it’s cost is a hot topic this month, with climatologist Radley Horton testifying on capitol hill about sea level rise.

“There has been a lot of focus on whether worst-case scenario for 2100 is 4.3 feet, six feet, or even eight feet of sea level rise,” he said. “Even the most optimistic scenario imaginable—of one foot of sea level rise by 2100—would have direct and profound impacts.”

Indeed, the house market has already responded and cost US coastal home owners nearly 16 billion in property value. Buyout programs in flood-prone areas are becoming more common, even as they come with their own shortcomings.

The insurance industry recognises that investors, lenders, insurers and policymakers undertake significant risk management efforts to minimise rising losses from climate-related hazards. Might more geoscientists be needed here?

As usual, I have many more interesting topics on offer for you, such as: humans have been present in ecosystems for a long stretch of time, so is there a place for us? Check out all stories below!

The importance of wetlands

The importance of wetlands

World Wetlands day is celebrated on 2nd February, marking the adoption of the Convention on Wetlands, also known as Ramsar Convention, in the Iranian city of Ramsar on 2nd February 1971. It “provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.

Today 170 countries have adopted it and 2,341 Ramsar sites covering over 2,5 million km² are designated as Wetlands of International Importance. But what are wetlands and why should we care about them? I’ll address these questions and other important points in this article.

First, what are wetlands?

Basically, a wetland is an area of land that is covered with water, whether natural or artificial, permanent or temporary. This water can be salt, fresh or somewhere in between, and have a maximum depth of six metres. Mangroves, marshes, ponds, peatlands, swamps, deltas, estuaries, low-lying areas that frequently flood are all wetlands and they can be found on every continent. Some of the largest ones are the Sundarbans mangrove forest in the Ganges-Brahmaputra delta in Bangladesh, the Amazon River basin (figure below), and the Pantanal, both in Brazil.

Wetlands cover about 3% of world’s surface. A web-based map shows the global distribution of wetlands and peat areas. It was launched in 2016 by researchers from Sustainable Wetlands Adaptation and Mitigation Program – SWAMP and is based on satellite images acquired by the  Moderate Resolution Imaging Spectroradiometer (MODIS) instrument.

Why should we care about wetlands?

Wetlands are rich but also fragile environments. They can provide water, fish/biodiveristy, recreational areas and help to regulate the climate.

  • Biodiversity: Wetlands function as wildlife refuge, supporting high concentration of mammals, birds, fish and invertebrates, being nurseries for many of these species.
  • Resources: Further, they can be a huge resource for humans, supporting rice paddies (Figure 2), a staple food. They also help purify water by trapping pollutants and heavy metals in the soil and neutralizing harmful bacteria by breaking down suspend solids in the water.
  • Geohazards: Wetlands provide flood control and storm protection in coastal areas acting like a sponge during storm events such as hurricanes, reducing their power of destruction.
  • Climate change: Here is another important point that I would like to highlight about wetlands. They play an important role in climate change mitigation and adaptation, since they store huge amounts of carbon. If you are curious about this topic, see this post where Heather [a regular contributor to the GfGD Blog] discusses how carbon is stored in peat soils in the tropics and the main threats to these areas.

Threatened environment

Despite their social and ecological importance, wetlands are continuously being degraded and even destroyed worldwide. According to this research the world has lost 64-71% of their wetlands since 1900 AD. Here is a list of the main threats towards wetlands:

  • Pollution: Generally located in low-lying areas, they receive fertilizers and pesticides from agricultural runoff, industrial effluents and households waste or sewage. These pollutants have detrimental effects on water quality and threaten the fauna and flora of wetlands. As I mentioned before, wetlands work as water filters, therefore there is a growing concern about how pollution will impact drinking water supplies and wetland biological diversity.
  • Agriculture and urbanization: One of the biggest threats to this environment is its drainage to make room for agriculture and human settlements. Such activities are an increasing threat and they destroy the ecosystem and all the benefits wetlands can provide.
  • Dams: The construction of a dam alters the natural flow of water through a landscape. This alteration may lead to an increase or decrease of water flow through a wetland, being potentially harmful for wetland ecosystems. Thus, it is essential to choose the location of a dam wisely, to reduce the impact on existing ecosystems.
  • Climate change: Climate change is shifting the world’s temperature and precipitation patterns. Wetlands are getting lost due both too much and too little water. Shallow coastal wetlands such as mangroves are being swamped because of sea level rise. In areas affected by droughts, estuaries, floodplains and marshes are drying up. Wetlands and climate change are the theme of World Wetlands Day in 2019.

Opportunities – taking action

Wetlands are a critical environment and their effective management can give a substantial contribution to biodiversity conservation and restoration, maintaining its bioecological characteristics and allowing the using of resources economically.

According to SWAMP, “carbon-rich mangroves and peatlands are high priorities in climate change adaptation and mitigation strategies throughout the world.”

With their partners, SWAMP have developed a collaborative agenda expected to raise the awareness about sustainable management of wetlands in changing world and livelihoods of local communities. The Ramsar Convention, an international agreement, is still important today because it supports environmental policy development and it encourages countries to commit to it. It is also valuable as an international forum for gathering and sharing knowledge about sustainable wetlands management. Also international NGOs such as Worldwide Fund for Nature (WWF) and Wetlands International play an important role.

Finally, regarding the Sustainable Development Goals (SDGs), recently Ramsar published a briefing note of how wetlands can contribute to their achievement. Access it hereto find out more details.

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:

In the late afternoon of 16 February people in Mexico City celebrate Chinese New Year when they hear an earthquake alarm. If you ever wondered what it is like to experience an earthquake, you should watch the videos in Austin Elliot’s The Trembling Earth blog. What do people do in the 78 seconds of earthquake early warning?

Next to stories on risk of landslide-induced floods in Papua New Guinea, the cost of waiting for a volcanic eruption to happen and other disaster risk discussion, this month is full of good articles on sustainability:

Earth has environmental limits, can we all live a good life in it?

Dan O’Neill from the University of Leeds notes that to achieve social thresholds, countries have needed to exceed multiple biophysical boundaries. He asks how we can ever live well within our planet’s natural boundaries and what this means for sustainable development.

Professor Steve Cohen at Columbia University’s Earth Institute sees a trend that may help with this sustainability problem. An increasing number of young people are drawn to sustainability education and the role of the sustainability professional is emerging. Steve argues these sustainability professionals must be scientifically literate and focus on the physical world.

More in this month, entrepreneurs start seeing opportunities in predicting climate change risks, geologists have found rock containing plastic, and a new massive open online course (MOOC) encourages its students to play a disaster risk reduction game.

As always, there’s a lot to read this month. This time I highlighted in bold the articles I think you should read first, so go ahead!
