Green infrastructure nature’s best defence against disasters

  • Member States and the private sector should increase investments in ecosystem restoration and protection, particularly water-related ecosystems, to reduce the disaster risk and impacts of climate change.
  • Ecosystems play a vital role in reducing the impacts of natural hazards and climate change and ecosystem-based approaches should be an integral part of disaster preparedness, emergency response, post-disaster recovery and reconstruction.
  • The Global Platform for Disaster Risk Reduction, held in Geneva, Switzerland from 13 to 17 May 2019 is the world's foremost gathering on reducing disaster risk and building resilience.
17 May 2019 – UN Member States today called for increased investments in ecosystem-based solutions for disaster prevention. Healthy ecosystems play a crucial role in preventing environmental disasters and mitigate climate change as well as reducing their harmful impacts.
Extreme weather patterns such as prolonged drought, flash floods and cyclones ­contribute to food insecurity, instability and migration. The latest devastating cyclones Idai and Kenneth, which hit Mozambique last spring, are cases in point. According to the UN Development Programme, “more than 100 million people could fall back into extreme poverty due to climate change [by 2030], while over 200 million people could be displaced due to more frequent and severe climatic disasters.”
The Global Platform for Disaster Risk Reduction, held in Geneva, Switzerland from 13 to 17 May 2019 is the world's foremost gathering on reducing disaster risk and building resilience. It provides a platform for Member States to share knowledge and report on the implementation process of the Sendai Framework for Disaster Risk Reduction, adopted in 2015.
UN Environment is a co-founder of the Partnership for Environment and Disaster Risk Reduction, a global alliance of 24 organizations that promotes ecosystem-based solutions to disaster risk reduction. The alliance calls for increased investments in ecosystem restoration and protection, with particular attention to lakes, swamps and peatlands to reduce the impacts of water-related disasters.
“Water is life, but water can also be a threat to life,” said Dr. Han Seung-Soo, former Prime Minister of South Korea, during his keynote speech. Water-related disasters account for almost 90 per cent of the 1,000 most disastrous events that have taken place since 1990.
As part of the Global Platform, UN Environment and the Partnership for Environment and Disaster Risk Reductionco-organized a high-level working session on integrating risk management of ecosystems and water-related risks, where participants identified key areas for substantial policy improvements and investments. UN Environment also launched Opportunity Mapping, a geospatial tool that helps Member States identify areas where large-scale ecosystem restoration and protection initiatives could take place. The tool also helps with reporting on green infrastructure, in compliance with international agreements such as the Sendai Monitor.
Another session focused on the role of green, blue and grey infrastructure in reducing disaster risk. A concrete measure put forward by the global disaster risk reduction community is the investment in resilient infrastructure, including meadows and forests (green infrastructure), and lakes, swamps and peatlands (blue infrastructure), which can be combined with dykes and seawalls (grey infrastructure) for cost-effectiveness and greater protection.
“Seventy per cent of the world we imagine in 2050 is yet to be built. We have a tremendous opportunity to build infrastructure that goes hand in hand with protecting nature. When we achieve this balance, we will reduce the risk of disasters and increase the resilience of communities,” said Joyce Msuya, Acting Executive Director of UN Environment.
According to the Intergovernmental Panel on Climate Change, “integrated coastal zone management should recognize the importance and economic expediency of using natural ecosystems such as mangroves and tropical coral reefs to protect coastal human communities.” Time and again, these natural buffer zones have proved invaluable to reduce the impacts of rising seas and intensifying storms.
Driving finance to ecosystem restoration and conservation is another important, much-needed pathway to reduce disaster risk. Innovative financial instruments for climate and disaster risk reduction are one of this year’s key topics at the Global Platform. Through its Principles for Sustainable Insurance Initiative, UN Environment has been promoting innovative insurance schemes such as the Restoration Insurance Service Company for Coastal Risk Reduction, a social enterprise that finances the restoration and conservation of mangrove habitats in vulnerable coastal areas in the Philippines.
A central element of the Sendai Framework is precisely the emphasis on addressing the underlying causes of disaster risk and preventing new risks, in addition to investing in disaster preparedness. The Sendai Framework – a 15-year, voluntary, non-binding agreement – gives governments the leading role in reducing disaster risk, a responsibility they share with other stakeholders such as local authorities and the private sector. Launched in early 2018, the Sendai Monitor helps Member States to report on their progress in achieving the global targets of the Sendai Framework.
UN Environment encourages Members States to recognize green and blue infrastructure as critical infrastructure, by enhancing national reporting in economic loss (Sendai Monitor target C) and critical infrastructure and services (target D).

7 eating habits that we know are good for us:

1. Eat plenty of vegetables and fruits – Some countries are very specific about the number of servings of fruits and vegetables that we should consume daily, for example Greece says six, Costa Rica and Iceland say five. Canada even specifies the colors of vegetables to consume (one dark green and one orange vegetable a day). Serving sizes can vary by country; however, all guidelines recommend eating plenty of fresh vegetables and fruits on a daily basis.

2. Watch your intake of fats– Said in different ways, most guidelines make mention of reducing solid, saturated fats and give recommendations for replacing animal fats with vegetable oils. In Greece, olive oil is recommended, in Viet Nam it is sesame or peanut oil – demonstrating the importance of availability and cultural preference in each country’s guidelines.3. Cut back on foods and beverages high in sugar – It is generally agreed upon that processed sugar is harmful to our health. The guidelines in every country recommend to maint…

Humans are a massive minority on Earth. Why don't we act like it?

Humans are a massive minority on Earth. Why don't we act like it?

Most of us, including scientists, are blind to the full scope of the living world. This was illustrated by an informal survey which asked biologists and ecologists from elite universities two questions. In terms of mass, is the living world mostly composed of animals, plants or bacteria? And is there more global biomass on land or in the oceans? The majority of them answered both questions incorrectly.In an age of unparalleled access to information, this is a glaring gap in our knowledge. We are now equipped to close it. I joined colleagues from the Weizmann Institute in Israel and the California Institute of Technology to estimate the biomass of all kingdoms of life on Earth. The results were published in the journal of the American National Academy of Sciences, and were widely (and more digestibly) covered by the popular press.It required years of work, collecting and integrating information from hundreds of previ…

Chart of the day: These countries create most of the world’s CO2 emissions

With CO2 levels on the rise, being able to track global emissions is crucial. Image: REUTERS/Regis Duvignau Just two countries, China and the US, are responsible for more than 40% of the world’s CO2 emissions. With CO2 levels still on the rise, being able to track the global emissions hotspots is becoming more important than ever. Before the industrial revolution, levels of atmospheric CO2 were around 280 parts per million (ppm). By 2013, that level had breached the 400ppm mark for the first time. On 3 June 2019 it stood at 414.40ppm. Fifteen countries are responsible for more than two thirds of global CO2 emissions. Image: Visual Capitalist There are huge disparities between the world’s top 15 CO2 emissions-generating countries. China creates almost double the emissions of second-placed US, which is in turn responsible for more than twice the level of third-placed India.
