To reduce water pollution and climate risks, the world needs to go beyond signing agreements and start acting. Translating agreements and policies into action is however always much more difficult than it might seem, because it requires all players involved to participate. A complete integration strategy across all sectors is needed. One of the advantages of integrating all sectors is that it would be possible to meet different objectives, for example, climate and water protection goals in this case, with the same strategy.

I was involved in a study that assessed the impacts of implementing various technologies to treat wastewater from the fish processing industry in Indonesia when involving different levels of governance. This study is part of the strategies that the government of Indonesia is evaluating to meet the greenhouse gas mitigation goals pledged in its Nationally Determined Contribution (NDC), as well as to reduce water pollution. Although Indonesia has severe national wastewater regulations, especially in the fish processing industry, these are not being strictly implemented due to lack of expertise, wastewater infrastructure, budgetary availability, and lack of stakeholder engagement. The objective of the study was to evaluate which technology would be the most appropriate and what levels of governance would need to be involved to simultaneously meet national climate and water quality targets in the country.

Seven different wastewater treatment technologies and governance levels were included in the analysis. The combinations included were: 1) Untreated/anaerobic lagoons – where untreated means wastewater is discharged without any treatment and anaerobic lagoons are ponds filled with wastewater that undergo anaerobic processes – combined with the current level of governance. 2) Aeration lagoons – which are wastewater treatment systems consisting of a pond with artificial aeration to promote the oxidation of wastewaters, plus activated sludge focused solely on water quality targets with no coordination between water and climate institutions. 3) Swimbed, which is an aerobic aeration tank focusing mainly on climate targets assuming no coordination between institutions. 4) Upflow anaerobic sludge blanket (UASB) technology, which is an anaerobic reactor with gas recovery and use followed by Swimbed, and 5) UASB with gas recovery and use followed by activated sludge, which is an aerobic treatment that uses microorganisms forming particles that clump together. Both, 4 and 5 assume vertical and horizontal coordination between water and climate institutions at national, regional, and local level. It is important to notice that the main difference between 4 and 5 is the technology used in the second step. Two additional combinations, 6 and 7, are also proposed including the same technological combinations of 4 and 5, but these include increasing the level of governance to a multi-actor coordination level. The multi-actor level includes coordination at all institutional levels but also involves academia, research institutes, international support, and other stakeholders.

Our results indicate that if the current situation continues, there would be an increase of greenhouse gases and water pollution between 2015 and 2030, driven by the growth in fish industry production volumes. Interestingly, the study also shows that focusing only on strengthening capacities to enforce national water policies would result in greenhouse gas emissions five times higher in 2030 than if the current situation continues, due to the increased electricity consumption and sludge production from the wastewater treatment process. The benefit of this strategy would be positive for the reduction of water pollution, but negative for climate change mitigation. From our analyses of combinations 2 and 3 we learned that technology can be very efficient for one purpose but detrimental for others. If different institutions are, for example, responsible for water quality and climate change mitigation, communication between the institutions is crucial to avoid trade-offs between environmental objectives.

Furthermore, when analyzing different cooperation strategies together with a combination of diverse sets of technologies, we found that not all combinations work appropriately. For instance, improving interaction just within and between institutions does not guarantee proper selection and application of technologies. In this case, the adoption of the technology is not fast enough to meet the targets proposed in 2030, thus resulting in policy implementation failures. Our analyses of combinations 4 and 5 showed that interaction within and between national, regional, and local institutions alone is not enough to prevent policy failure.

Finally, a multi-actor cooperation strategy that includes cooperation across sectors, administrative levels, international support, and stakeholders, seems to be the right approach to ensure selection of the most appropriate technologies and achieve policy success. We identified that with this approach, it would be possible to reduce water pollution and simultaneously decrease greenhouse gas emissions from the electricity required for wastewater treatment. Analyzing combinations 6 and 7 revealed that multi-actor governance allows to simultaneously meet climate and water objectives and a high chance to prevent policy failure.

In the end, analyses such as the one shown here, highlight the importance of integrating and creating synergies across sectors, administrative levels, stakeholders, and international institutions to ensure an effective implementation of policies that provide incentives to make careful choices regarding multi-objective treatment technologies.

Ethical research is a quest for truth

Bettina Greenwell, communications officer at IIASA, talks to Dorsamy (Gansen) Pillay, Deputy CEO: Research and Innovation Support and Advancement (RISA), National Research Foundation (NRF), and IIASA council member for South Africa, about the NRF’s statement on ethical research and scholarly publishing practices. The statement was jointly issued in August 2019 with South African partners within the National System of Innovation (NSI) in South Africa.

What is ethics in research and why is it so important?

Research is a quest for truth. The research must be well conceptualized with a clear research question(s) which can lead to new knowledge. Good ethics and integrity dictate that the truth must be presented in its absolute form, and the findings need to be appropriately interpreted and should be reproducible. 

South Africa was awarded the right to host the 7th World Conference on Research Integrity (WCRI) in 2021 in Cape Town – the first time it will be hosted on an African continent. Why is this statement important for the science community in South Africa?

Firstly, it is a privilege to host this conference and South Africa feels very honored. The statement on ethical research and scholarly publishing practices is an important contribution to this conference. We have noticed that South African academics and researchers, especially new and emerging researchers, are under a lot of pressure to publish their work for a variety of reasons. In some instances, ethical principles have been violated. This included the dissemination of research through predatory journals.  However, this was not unique to South Africa only as other countries also faced similar challenges.  The NRF as a science granting foundation felt compelled to respond to this challenge. The NRF sees itself as a custodian and guardian of research ethics and integrity. Through our peer-review processes, we ensure that research proposals for funding have been robustly interrogated, and the highest ethical principles upheld. As a consequence the NRF developed and issued a joint statement on ethical research and scholarly publications in collaboration with the Department of Science and Innovation (DSI), the Department of Higher Education and Training (DHET), the Council on Higher Education (CHE), the Academy of science of South Africa (ASSAf), Universities South African (USAf) and the NRF. In addition, the NRF has previously issued a statement on predatory publishing.

What do you think will be the key scientific challenges to face South Africa in the next few years? And how do you envision IIASA helping South Africa to tackle these?

There are several challenges, and some of the most pressing ones are poverty and inequality, population migration and unemployment. Given the systems analysis approach, we feel we can draw on IIASA’s expertise to address these challenges. IIASA has used South Africa as a laboratory for its population studies research over several years. It is now time to ensure that this research is translated into policies so that it may impact positively on society.

Housing is also a problem in South Africa. There is a lack of decent, affordable housing for people. The new IIASA strategic plan focuses on smart cities – this could play a role in addressing these housing challenges.

IIASA’s expertise is a systems analysis approach which can be applied to complex issues. The important part of the work is when scientific results are turned into policy – that’s when there is an actual, tangible societal benefit.

South Africa has been an IIASA member since 2007. What have been the highlights of the South Africa-IIASA membership until now? 

We see the South Africa IIASA membership as a partnership, and many benefits have accrued through this partnership over the past decade. An example is the Southern African Young Scientists Summer Program (SA-YSSP), which was inspired by the success of the IIASA YSSP. This program ran from 2012 to 2015, and trained the next generation of young scientists.

Another example is the Southern African Systems Analysis Centre (SASAC) initiative, which focused on expanding systems analysis expertise in Southern Africa. Both initiatives were endorsed by the South African Department of Science and Innovation.

Perspectives on transforming food and land use systems for sustainable development

By Frank Sperling, Senior Project Manager (FABLE) in the IIASA Ecosystems Services and Management Program

Food and land use systems play a critical role in managing climate risks and bringing the world onto a sustainable development trajectory.

The UN Secretary General’s Climate Action Summit in New York on 23 September seeks to catalyze further momentum for climate change mitigation and adaptation. The transformation of the food and land use system will play a critical role in managing climate risks and bringing the world onto a sustainable development trajectory.

Today’s food and land use systems are confronted with a great variety of challenges. This includes delivering on universal food security and better diets by 2030. Over the last decades, great strides have been made towards achieving universal food security, but this progress recently grinded to a halt. The number of people suffering from chronic hunger has been rising again from below 800 million in 2015 to over 820 million people today [1]. Food security is however not only about a sufficient supply of calories per person. It is also about improving diets, addressing the worldwide increase in the prevalence of obesity, and how we use and value environmental goods and services.

Agriculture, forestry and other land use currently account for around 24% of greenhouse gas emissions caused by human activities [2]. Land use changes are also a major driver behind the worldwide loss of biodiversity [3]. Clearly, in light of population growth and the increasingly visible fingerprints of a human-induced global climate crisis and other environmental changes, business as usual is not an option.

Systems thinking is key in shifting towards more sustainable practices. A new report released by the Food and Land-Use System (FOLU) Coalition showcases that there is much to be gained. There are massive hidden costs in our current food and land use systems. The report outlines ten critical transitions, which can substantially reduce these hidden costs, thereby generating an economic prize, while improving human and planetary health.

The International Institute for Applied Systems Analysis (IIASA) contributed to the analytics underpinning the report [4], applying the Global Biosphere Management Model (GLOBIOM) [5]. A “better futures” scenario, which seeks to collectively address development and environmental objectives, was compared to a “current trends” scenario, which is basically a continuation of a business-as-usual scenario. The assessment illustrates that an integrated approach that acknowledges the interactions in the food and land use space, can help identify synergies and manage trade-offs across sectors. For example, shifting towards healthy diets not only improves human health, but also reduces pressure on land, thereby helping to improve the solution space for addressing climate change and halting biodiversity loss.

While understanding that the global picture is important, practical solutions require engagement with national and subnational governments. The challenge is to identify development pathways that address the development needs and aspirations of countries within global sustainability contexts. As part of FOLU, the Food, Agriculture, Biodiversity, Land and Energy (FABLE) Consortium was initiated to do exactly this. The FABLE Secretariat, jointly hosted by the Sustainable Development Solutions Network (SDSN) and IIASA, is working with knowledge institutions from developed and developing countries, to explore the interactions between national and global level objectives and their implications for pathways towards sustainable food and land use systems. Preliminary results from inter-active scenario and development planning exercises, so-called Scenathons, were recently presented in the FABLE 2019 report.

These initiatives highlight that acknowledging and embracing complexity can help reconcile development and environmental interests. This also entails rethinking how we relate to and manage nature’s services and their role in providing the foundation for the welfare of current and future generations. This is underscored by the prominent role nature-based solutions are given at the UN Secretary General’s Climate Action Summit. We need to move from silo-based, sector specific, single objective approaches to a focus on multiple objective solutions. In the land use space, this means embedding agriculture in the broader land use context, which accounts for and values environmental services, and linking to the food system where dietary choices shape human health and the demand for land.

Doing so will help bridge the international policy objectives of the UN Framework Convention on Climate Change (UNFCCC), the UN Convention on Combating Desertification (UNCCD), the Convention on Biological Diversity (CBD), and the Sustainable Development Goals (SDGs) enshrined in ‘The 2030 Agenda for Sustainable Development’. This represents an opportunity to create a new value proposition for agriculture and other land use activities where environmental stewardship is rewarded.

5 years of Vietnam membership at IIASA

Tran Thi Vo-Quyen, IIASA guest research scholar from the Vietnam Academy of Science and Technology (VAST), talks to Professor Dr. Ninh Khac Ban, Director General of the International Cooperation Department at VAST and IIASA council member for Vietnam, about achievements and challenges that Vietnam has faced in the last 5 years, and how IIASA research will help Vietnam and VAST in the future.

Professor Dr. Ninh Khac Ban, Director General of the International Cooperation Department at VAST and IIASA council member for Vietnam

What have been the highlights of Vietnam-IIASA membership until now?

In 2017, IIASA and VAST researchers started working on a joint project to support air pollution management in the Hanoi region which ultimately led to the successful development of the IIASA Greenhouse Gas – Air  Pollution Interactions and Synergies (GAINS) model for the Hanoi region. The success of the project will contribute to a system for forecasting the changing trend of air pollution and will help local policy makers develop cost effective policy and management plans for improving air quality, in particular, in Hanoi and more widely in Vietnam.

IIASA capacity building programs have also been successful for Vietnam, with a participant of the 2017 Young Scientists Summer Program (YSSP) becoming a key coordinator of the GAINS project. VAST has also benefited from two members of its International Cooperation Department visiting the IIASA External Relations Department for a period of 3 months in 2018 and 2019, to learn about how IIASA deals with its National Member Organizations (NMOs) and to assist IIASA in developing its activities with Vietnam.

What do you think will be the key scientific challenges to face Vietnam in the next few years? And how do you envision IIASA helping Vietnam to tackle these? 

In the global context Vietnam is facing many challenges relating to climate change, energy issues and environmental pollution, which will continue in the coming years. IIASA can help key members of Vietnam’s scientific community to build specific scenarios, access in-depth knowledge and obtain global data that will help them advise Vietnamese government officials on how best they can overcome the negative impact of these issues.

As Director General of the International Cooperation Department, can you explain your role in VAST and as representative to IIASA in a little more detail?

In leading the International Cooperation Department at VAST, I coordinate all collaborative science and technology activities between VAST and more than 50 international partner institutions that collaborate with VAST.

As the IIASA council representative for Vietnam, I participate in the biannual meeting for the IIASA council, I was also a member of the recent task force developed to implement the recommendations of a recent independent review of the institute. I was involved in consulting on the future strategies, organizational structure, NMO value proposition and need to improve the management system of IIASA.

In Vietnam, I advised on the establishment of a Vietnam network for joining IIASA and I implement IIASA-Vietnam activities, coordinating with other IIASA NMOs to ensure Vietnam is well represented in their countries.

You mentioned the development of the Vietnam-IIASA GAINS Model. Can you explain why this was so important to Vietnam and how it is helping to improve air quality and shape Vietnamese policy around air pollution? 

Air pollution levels in Vietnam in the last years has had an adverse effect on public health and has caused significant environmental degradation, including greenhouse gas (GHG) emissions, undermining the potential for sustainable socioeconomic development of the country and impacting the poor. It was important for Vietnam to use IIASA researchers’ expertise and models to help them improve the current situation, and to help Vietnam in developing the scientific infrastructure for a long-lasting science-policy interface for air quality management.

The project is helping Vietnamese researchers in a number of ways, including helping us to develop a multi-disciplinary research community in Vietnam on integrated air quality management, and in providing local decision makers with the capacity to develop cost-effective management plans for the Hanoi metropolitan area and surrounding regions and, in the longer-term, the whole of Vietnam.

Facilitating sustainable energy transitions at the top of the world

By Pallav Purohit, researcher with the IIASA Air Quality and Greenhouse Gases Program

More than 300 million people in Hindu Kush Himalaya-countries still lack basic access to electricity. Pallav Purohit writes about recent research that looked into how the issue of energy poverty in the region can be addressed.

The Hindu Kush Himalayas is one of the largest mountain systems in the world, covering 4.2 million km2 across eight countries: Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, and Pakistan. The region is home to the world’s highest peaks, unique cultures, diverse flora and fauna, and a vast reserve of natural resources.

Ensuring access to affordable, reliable, sustainable, and modern energy for all – the UN’s Sustainable Development Goal (SDG) 7 – has however been especially elusive in this region, where energy poverty is shockingly high. About 80% of the population don’t have access to clean energy and depend on biomass – mostly fuelwood – for both cooking and heating. In fact, over 300 million people in Hindu Kush Himalaya-countries still lack basic access to electricity, while vast hydropower potentials remain largely untapped. Although a large percentage of these energy deprived populations live in rural mountain areas that fall far behind the national access rates, mountain-specific energy access data that reflects the realities of mountain energy poverty barely exists.

Source: Wester et al. (2019)

The big challenge in this regard is to simultaneously address the issues of energy poverty, energy security, and climate change while attaining multiple SDGs. The growing sectoral interdependencies in energy, climate, water, and food make it crucial for policymakers to understand cross-sectoral policy linkages and their effects at multiple scales. In our research, we critically examined the diverse aspects of the energy outlook of the Hindu Kush Himalayas, including demand-and-supply patterns; national policies, programmes, and institutions; emerging challenges and opportunities; and possible transformational pathways for sustainable energy.

Our recently published results show that the region can attain energy security by tapping into the full potential of hydropower and other renewables. Success, however, will critically depend on removing policy-, institutional-, financial-, and capacity barriers that now perpetuate energy poverty and vulnerability in mountain communities. Measures to enhance energy supply have had less than satisfactory results because of low prioritization and a failure to address the challenges of remoteness and fragility, while inadequate data and analyses are a major barrier to designing context specific interventions.

In the majority of Hindu Kush Himalaya-countries, existing national policy frameworks currently primarily focus on electrification for household lighting, with limited attention paid to energy for clean cooking and heating. A coherent mountain-specific policy framework therefore needs to be well integrated in national development strategies and translated into action. Quantitative targets and quality specifications of alternative energy options based on an explicit recognition of the full costs and benefits of each option, should be the basis for designing policies and prioritizing actions and investments. In this regard, a high-level, empowered, regional mechanism should be established to strengthen regional energy trade and cooperation, with a focus on prioritizing the use of locally available energy resources.

Some countries in the region have scaled up off-grid initiatives that are globally recognized as successful. We however found that the special challenges faced by mountain communities – especially in terms of economies of scale, inaccessibility, fragility, marginality, access to infrastructure and resources, poverty levels, and capability gaps – thwart the large-scale replication of several best practice innovative business models and off-grid renewable energy solutions that are making inroads into some Hindu Kush Himalayan countries.

This further highlights an urgent need to establish supportive policy, legal, and institutional frameworks as well as innovations in mountain-specific technology and financing. In addition, enhanced multi-stakeholder capacity building at all levels will be needed for the upscaling of successful energy programs in off-grid mountain areas.

Finally, it is important to note that sustainable energy transition is a shared responsibility. To accelerate progress and make it meaningful, all key stakeholders must work together towards a sustainable energy transition. The world needs to engage with the Hindu Kush Himalayas to define an ambitious new energy vision: one that involves building an inclusive green society and economy, with mountain communities enjoying modern, affordable, reliable, and sustainable energy to improve their lives and the environment.
