About Sustainability… is a podcast presented by the Institute for Global Environmental Strategies, featuring IGES staff and guests having in-depth discussions about sustainability-related topics. Each episode addresses a different topic of conversation -- be it an upcoming event, a debate of interest, or an interesting research finding. With the topic as a starting point, we see where the conversation takes us. We aim at a broad audience, so we avoid using jargon and try not to assume lots of pre-existing knowledge on the topic. Views expressed during the podcast are those of the speaker at the time of recording and are not the official positions of IGES or other organisations involved.

The Science of Change (Part 1): Behavioural Insights for Sustainability
2025/11/14
Welcome to About Sustainability…, a podcast brought to you by the Institute for Global Environmental Strategies (IGES).
In this episode, hosts Dwayne Appleby and Alice Yamabe are joined by Philipe Bujold, Senior Behavioural Scientist at Rare’s Centre for Behavior & the Environment.
The Center for Behavior & the Environment (BE.Center) at Rare is an international non-profit that works to put behavioural science into practice, applying behavioural insights and design thinking to address issues such as climate change, coastal overfishing, plastic pollution, and biodiversity loss.
This episode is the first in a three part series exploring how behavioral science can help us tackle some of today's most urgent environmental challenges. We discussed what behavioural science is, where it comes from, and how organisations like Rare are applying behavioural insights to real world issues. We explore key concepts such as nudges, sludges and behavioural levers.

Depopulation, shrinking cities and urban-rural migration
2024/10/02
In this episode Alice Yamabe and Andre Mader speak with two IGES colleagues, Fernando Ortiz Moya and Yasuo Takahashi, about the phenomenon of depopulation. Fernando has been studying shrinking cities, and Yasuo has been doing research on urban to rural migration, so we have two quite different angles on this subject.
To many it may seem counterintuitive to worry about depopulation in a world in which the human populations continues to grow. But population growth rates have been slowing for decades, and have become negative in a growing list of countries. Interestingly, at least in Japan, this has not necessarily been good for people or the environment. On the other hand, perhaps we need to accept and adapt to this reality.

Let's talk about the material footprint and its significance for sustainability
2024/06/26
In this episode of About Sustainability, we talked to Heinz Schandl, who joined us from the Commonwealth Scientific and Industrial Research Organisation (CSIRO), which is an Australian Government agency responsible for scientific research. He is an expert on natural resource use, and international resource flows. Among other things, Heinz explained about resource efficiency, the socioeconomic drivers of resource use, and about the possibilities of decoupling economic development and human well-being from resource use.
He also explained how resource use is measured through what we call the material footprint, and why it is important to capture the international dimension of that footprint.
We also learned about progress in indicators and data availability so that the international linkages between resource extraction and final consumption can be tracked and managed.
All these items are important for measuring progress across several SDGs including SDG 8 on decent work and economic growth, and SDG 12 on sustainable consumption and production.

A few perspectives on UNEP's 6th Environment Assembly and its "OECPR"
2024/05/09
In this episode Alice and Andre talked to Simon about the United Nations Environment Assembly, also known as UNEA, which is the decision-making body of the United Nations Environment Programme. UNEA takes place in Nairobi every second year and it is always preceded by the so-called OECPR, which stands for the Open-ended Committee of Permanent Representatives. This committee functions as the working level meeting that prepares decisions and resolutions for official approval by UNEA. This year, UNEA-6 took place in late February and I joined some of the preparations for that meeting, so in this episode we discuss some of the things that took place during the OECPR and UNEA to draw attention to those processes of international environmental governance that influence the agenda of domestic environmental policy making. Join us and listen.

Looking back on the career of emeritus IGES Executive Director, Hideyuki Mori
2024/03/28
On this episode of About Sustainability…, Andre, Alice and Simon celebrate the contribution of an IGES legend, Mr Hideyuki Mori. Mori-san has been a leader at IGES for most of the institute’s history, following diverse experience at other institutions including the United Nations Environment Programme and Asian Development Bank. He retired last year and we wanted to speak to him about his career including his long tenure at IGES. In this discussion we also reminisce about long-time colleague Peter King, who appeared on the podcast last year, but unexpectedly passed away a few months ago. Mori-san and Peter were friends, and played a key role in steering IGES’ course as in international institute.
This episode will probably be of particular interest to IGES staff members or prospective IGES staff, but there should be something for anyone who is interested in careers in the environment.

About Climate Action (SDG 13): Framing Climate Change as a Security Issue and Outcomes of UNFCCC-COP28
2024/01/31
On this episode of About Sustainability…, Alice and Erin were joined by Naoyuki OKANO and Nagisa SHIIBA, IGES experts working on Climate Adaptation. This episode, recorded in December 2023, offers a quick recap of what happened at COP28 in Dubai and then dives deep into the far-reaching impacts of climate change on human security.
Hosted in Dubai, United Arab Emirates, the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP28) brought the world’s leaders together to discuss how to confront the climate crisis. Some of its main outcomes include the first Global Stocktake (GST), the agreement on the framework for operationalising the Global Goal on Adaptation (GGA), and the agreement on the operationalisation of the Loss and Damage Fund.
Naoyuki and Nagisa introduce us to their new research project on Climate Security in the Asia Pacific, funded by the Japanese Ministry of Foreign Affairs. We discuss how framing the climate crisis as a security issue can be a powerful approach to mobilising resources across areas and tackling global challenges.
ABOUT OUR GUESTS
Dr. Naoyuki OKANO is a Policy Researcher in the Adaptation and Water Unit of IGES. He works on issues related to the laws and governance of climate change adaptation, nature-based solutions, transboundary climate risks, and climate security.

On this episode of About Sustainability…, Erin, Alice, and Simon were joined by Matthew Hengesbaugh and Chochoe Devaporihartakula, IGES experts working on plastic pollution. While plastics have been an indispensable part of modern life, plastic pollution has entered the public consciousness in recent years. It is an issue that most of us encounter every day.
The United Nations Environment Assembly (UNEA) agreed in 2022 to create an intergovernmental negotiating committee (INC) to establish a legally binding instrument to end plastic pollution.
We discussed how serious plastic pollution is in Asia, what the INC is trying to achieve, what was discussed at the recent meeting (INC-3) including the challenges that emerged, and what is needed for an ambitious treaty to tackle this transboundary issue.
About our guests:
Chochoe Devaporihartakula manages the regional project portfolio addressing plastics and marine pollution at the IGES Bangkok Regional Centre. She also serves as a Programme Manager for the Asian Environmental Compliance and Enforcement Network, where she is dedicated to promoting improved compliance with environmental laws and regulations through environmental agencies across 18 countries in Asia.

Updates from the ongoing political and scientific processes to reduce plastic pollution
2023/01/27
In this episode we met with Amila from IGES who shared the latest updates on international plastics governance. Among others, he described details on the international negotiations committee that was formed last year to define a legally binding instrument to curb plastic pollution. We heard who is on that committee and what they do when they meet. He also explained details and challenges around what is called the life cycle approach and explained why experts are working on approaches to account for the impacts of plastics throughout its entire life cycle. In this regard we were also able to hear some examples of the work he and his colleagues are doing to help build the needed capacity at local levels to measure plastic pollution and to be able to take steps to reduce it.

SDG6: Water, water everywhere, but how is it managed?
2023/01/10
In this episode of About Sustainability…
Erin and Bob talked to Binaya Raj Shivakoti, an IGES expert in the Adaptation and Water team, about SDG6, which is on “ensuring availability and sustainable management of water and sanitation for all” (or simply ‘Clean Water and Sanitation’). This goal’s environmental dimensions are clear, and has targets on the universal and equitable access to safe and affordable drinking water, sanitation, and hygiene for all; improving water quality and water-use efficiency; implementing integrated water resource management; protecting and restoring water-related ecosystems; fostering international cooperation, and involving local communities in water and sanitation management.
During our chat, we talked about water being fundamental to all aspects of life and what life can be like for communities without access to these basic needs. We then explored integrated water resource management (IWRM), which Binaya argued is a natural starting point for implementing all the SDGs.

SDG5: Achieve gender equality and empower all women and girls
2022/12/27
In this episode of About Sustainability..., Andre and Erin spoke with their colleague, Maiko Morishita, about SDG5, on achieving gender equality and empowering all women and girls. Maiko is part of the IGES finance task force, which covers a variety of topics but she also previously worked in the NGO world where gender was a key component of her work. We started by asking Maiko why she thinks this goal is important. We then proceeded through a winding conversation that touches on various aspects of SDG5, albeit not all aspects of this diverse goal. The idea was to explore this SDG and really dig into some of the ideas behind it. So we hope it provides a bit of depth and a bit of breadth, and hopefully some fresh perspectives.
