China is the world’s biggest producer of both wild and farmed fish, yet the massive commercial fishing industry threatens thousands of years of tradition in ocean and freshwater fishing, as well as the livelihoods of coastal fishing communities.
In the past decade, some coastal ecosystems and environments have been destroyed and polluted in the process of industrialization. Millions of tons of fish are caught in Chinese territorial waters each year, such that overfishing of high value commercial species has led to a drastic decline of some native fisheries resources and species.
In response, the Chinese government released a five-year plan for protecting marine ecosystems and restoring wild capture fisheries. The plan promotes an agenda of “ecocivilization,” which emphasizes land–sea coordination, green development, and social–ecological balance.
It also calls for the introduction of additional output control measures, which directly limit the amount of fish coming out of a fishery. Existing input control measures restrict the intensity of gear used to catch fish, but they may not be sufficient to protect ecosystems.
Yi Huang, a member of this year’s YSSP cohort, has made it her goal to figure out how social ecological balance can be achieved even as fishery regulations shift towards increased input and output control.
Given the size of China’s fishing industry, large scale change requires the abstract concepts of “ecocivilization” to be translated into action, compliance, and enforcement at the local level. That means engaging with individual fishers, their communities, and their way of life, says Huang.
“If you want to control overfishing; the object of fishery management policy are fishers. So you need to understand human behavior to help you control overfishing.”
Huang’s project investigates how changes in fishery management will affect demographic, geographic, and socioeconomic trends in the Chinese fisher population. With the guidance of her supervisors, she’s also developing a bioeconomic model to analyze how output control measures like catch limits will affect ecological and socioeconomic conditions.
“I just want to figure out how to improve enforcement of this kind of policy and see if we can use it to solve the overfishing problem at the same time as giving those in the fishing industry a better life,” says Huang.
Current input control measures like licensing systems, vessel buyback programs, closed seasons, restricted areas, and fisher relocation programs are meant to discourage overfishing and transition towards more sustainable practices. Nevertheless, a decline in fishing vessels and restricted fishing seasons only resulted in an increase in total vessel engine power and large spikes in fishing activity just prior to the closed season.
According to the Chinese fishery statistical yearbook, the number of people employed in the fishing industry proliferated to 13.8 million in 2016, so in recent years the government has issued subsidies encouraging fishers not to fish in the off-season and to change vocation. Older fishers are hesitant to abandon an identity that has been passed down from generation to generation in their families. However, younger generations with access to higher education are lured by the prospect of more stable work outside of their fishing communities, which could really change the socioeconomic and demographic structure of coastal villages.
With the potential for increased output controls to incur drastic changes in coastal communities, it’s more important than ever that regulations are carefully designed with both socioeconomic and ecological factors in mind.
Huang hopes her research will help inform the process of policy development, which involves balancing the needs of both vulnerable fisheries labor and delicate ecosystems.
“When policymakers want to use output control in fishery management, maybe they will think more about the fisher or the socioeconomic aspect of the resolution,” says Huang.
“My research is at the national level, but when they design a regulation it’s at the local level, so my research can teach them how socioeconomic surveys at the local level can be used together with ecological research when they are preparing for regulations.”
Huang, who studied sociology at the Ocean University of China before starting as a PhD student in Marine Affairs at Xiamen University, has spent the past ten years researching coastal fishing communities. She has a deep fondness for the people she surveyed, who welcomed her into their homes and showed her the beauty of the environment that sustained them.
“I want to protect the ocean and the people that connect with it,” says Huang.
A sociological perspective has given Huang an eye for nuance and an appreciation for things that don’t turn out quite how you expect, as they often don’t in scientific research—especially when it attempts to explain human behavior.
For example, Huang says that although fishers may look like countryside people, they act very differently from farmers.
“The ocean has a lot more risk involved than planting on land,” explains Huang.
Because Chinese fishery regulation is currently focused almost exclusively on analyzing resources from an ecological perspective, she thinks sociology and anthropology research could add another revealing dimension to the approach.
“After doing surveys and analyzing the data, I will find maybe I’m wrong or maybe there is something more. That’s why I’m really interested in this kind of research,” says Huang.
As her research project develops, Huang says she’s grateful for the feedback of her supervisors and peers at IIASA, who both challenge and encourage her.
“Even when they have some critical comments on my research, I feel more confident that my research is meaningful, that they support me, and that they’re really interested in my research,” says Huang. “That’s what I can feel every day.”

Strategic board games are staple entertainment for families all over the world, but what many do not know is that games can also be a valuable research tool. As her project for the Young Scientists Summer Program (YSSP), Sara Turner is piloting an experiment that uses a game called the Forest Game, developed by IIASA and the Centre for Systems Solutions, to find out how policy decisions are made and how they change over time. “Games let you abstract from the specifics of a real-world case, but are more human-centric than, for example, computer simulations,” says Turner.
In the Forest Game, a group of five to ten players is asked to make decisions about the management of a forest together. Harvesting trees yields returns for the players, while harvesting too many of them might destroy the forest or increase the risk of flooding. There are some uncertainties in the game – for example, the players do not know exactly how resilient the forest is. The goal of the research project is to run multiple iterations of the game with different players and starting conditions, and trace how group discussions and the resulting decisions change over time. This helps to generate hypotheses about the ways in which individuals interact to generate policy outcomes. Each game takes about an hour to play.
Even though the Forest Game deals with forest management, this is only one example of a broader class of decision-making dilemma: when a resource is limited, and it is costly to prevent access, people will tend to over-exploit the resource. This in turn leads to a wide range of problems, from over-fishing to air pollution. Although games cannot capture the complexity of real situations, they can still help us understand the core dynamics of the problem and develop ideas and strategies that are relevant to solving it. “The game is not designed to be directly applicable to real life, but it helps to come up with hypotheses that you can then compare to real-life cases,” explains Turner.
Questions about the sustainable management of resources have been studied for decades, but not a lot is known about the role values play in shaping group decision making and the stability of the implemented policies. To investigate this, each participant is asked to fill out a short ten-minute survey assessing their core values and beliefs, after which they are put into a group with people who either have a very similar or very different worldview from them. “It is really interesting to put a person in a decision-making context with other people and get some insight into how they work through that problem,” says Turner.
For example, if you are a person that strongly values equality, in the game you might be likely to argue in favor of a policy where all participants obtain the same amount of returns, regardless of the number of trees the individual player chooses to harvest. If many players in the group share your belief, that policy might be more likely to be implemented than in a very diverse group.
Another interesting question whenever you run a game for research purposes is, “Who are the right players?” Some games are targeted at real-world policymakers, but often games can also be educational for the broader public. ‘’People learn a lot during games, because of the way that information is processed and experienced,” says Turner. That is why many participants, although they might not see a connection between the game and their life at first, find themselves relying on the insights they gained while playing when faced with similar situations in the future.
In this case, the goal is to study group decision-making processes in general, so the details of who is playing are not particularly important. However, to obtain groups of players with heterogeneous worldviews, a high degree of diversity is preferable.
While the game has previously mainly been played by YSSP participants and students of the University of Vienna, Turner is currently trying to recruit a more diverse set of players from both within and outside of IIASA. “It would be ideal to have a pool of participants who come from a wide variety of educational and cultural backgrounds,” she says.

Imagine you are heading home from work and are stuck in evening rush hour traffic. You see an opportunity to save time by cutting another driver off, but this will lead to a delay for other cars, possibly causing a traffic jam. Would you do it? Situations like these, where you can benefit from acting selfishly while causing the community as a whole to be worse off, are known as social dilemmas, and are at the heart of many areas of research in economics.
The social dilemma becomes particularly important when considering so-called common pool resources such as water reservoirs that are depleted when people use them. For instance, picture several farmers using water from the same river to irrigate their farmland. The river might carry enough water for all of them, but if there is no incentive for the upstream farmers to take the needs of the farmers living further downstream into consideration, they might use more than their share of the water, not leaving enough for the rest of the group. Situations like this are particularly relevant in developing countries, where small-scale farmers that manage the irrigation of their farmland themselves play a significant role in ensuring food security.
Growing up in southwestern Cambodia, YSSP participant Tum Nhim saw how the surrounding farmers shared water among themselves, and how important water was to their livelihoods. Not having enough water often meant that there were no crops for a whole year, and many farmers were forced to take on loans in order to feed their families. “Now that climate change is starting to affect Cambodia, and water scarcity is becoming an even bigger problem, it is more important than ever to investigate fair and efficient ways of sharing water,” explains Nhim.
As a water engineer, Nhim used to design and build water infrastructure. He however soon learned that not considering how human decision making affects the water supply will cause situations where the infrastructure provides enough water, but some farmers are still left high and dry. “I think that human behavior is the most important factor to consider when managing common pool resources,” he says.
To find possible solutions for distributing water in a way that yields an optimal outcome for the community, Nhim and his colleagues from the IIASA Advanced Systems Analysis Program use a bottom-up approach–they model the behavior of a number of individual farmers that interact according to certain rules. The researchers can then look at the collective outcome of these interactions after a certain time and ask questions like, “Will the farmers cooperate?” or, “Will some farmers be left without water?” In their model the researchers take into account both the water itself, a common pool resource, and the water infrastructure, which is not depleted by use.
Several mechanisms can be used to ensure the fair distribution of water. Some of them are formal; like laws and regulations, but it is often difficult to keep people from extracting water, because using a given water resource might be a long-standing cultural tradition or legal right. There are however also more informal mechanisms that can help. For example, individuals often prefer to be good citizens in order to ensure that they have a high social standing in their community that will bring them benefits.
This reputational mechanism is especially relevant in small communities with everyday contact between members. If someone takes too much water, or doesn’t invest in the common water infrastructure, they will gain a bad reputation, which will in turn limit their ability to get support from their neighbors later on.
The main question Nhim is investigating in his YSSP project is if this mechanism can spread across several villages that share a common water resource and irrigation infrastructure, and lead to an outcome where everyone cooperates. If this turns out to be true, the reputational mechanism could be a very inexpensive and natural solution for managing common goods across several communities.

When it comes to home cooking in rural India, health, behavior, and technology are essential ingredients.
Consider the government’s three-year campaign to reduce the damaging impacts of solid fuels traditionally used in rural households below the poverty line.
Initiated by the Ministry of Petroleum and Natural Gas, a program called Pradhan Mantri Ujjwala Yojana (Ujjwala) aims to safeguard the health of women and children by providing them access to a clean cooking fuel, liquid petroleum gas (LPG), so that they don’t have to compromise their health in smoky kitchens or wander in unsafe areas collecting firewood.
According to the World Health Organization, smoke inhaled by women and children from unclean fuel is equivalent to burning 400 cigarettes in an hour.
Nevertheless, an estimated 700 million people in India still rely on solid fuels and traditional cooking stoves in their homes. A subsidy of Rs. 1600 (US $23.47) and an interest free loan attempts to offset the discouraging cost of the upfront security deposit, the stove, and the first bottle of LPG, but this measure hasn’t been able to change habits on its own.
Why? Although the government has made an overwhelming effort to increase access, interconnected factors like cultural norms, economic trade-offs, and convenience require an in-depth analysis of human behavior and decision-making.
That’s why Abhishek Kar, a researcher in the IIASA Energy Program and a participant in the 2018 Young Scientists Summer Program (YSSP), has designed a study to explore how rural households make choices about access and usage. Borrowing from behavior change and technology adoption theories, he wants to know whether low-cost access is enough incentive for Ujjwala beneficiaries to match the general rural consumption trends, and more importantly, how to translate public perception into a behavior change.
“I think it’s really important to look into the behavioral aspect,” said Kar in an interview. “If you ask someone if they think clean cooking is wise they may say yes, but if you say do you think it is appropriate for you? The moment it becomes personalized the answers can vary.”
Kar knows that although more than 41 million LPG connections have been installed, installment of the connection does not necessarily equate to use. By gathering data on LPG refill purchases and trends, along with surveys that identify biases in the public’s perception, he wants to know how to convince rural BPL households to maintain the habit of using LPG regularly, even under adverse conditions like price hikes. If LPG is used only sporadically, LPG ownership won’t significantly reduce risk for some household air pollution (HAP)-linked deadly diseases, like lower respiratory infections and stroke.
Unfortunately, even the substantial efforts the government has made to improve LPG supply has not changed the public’s perception of its accessibility in the long term, nor its consumption patterns in the first two years. At least four LPG refills per year would be needed for a family of five to use LPG as a primary cooking fuel, which is not currently happening for the majority of Ujjwala customers.
Because the majority of Ujjwala beneficiaries have cost-free access to solid fuels from forest and agricultural fields, there is less incentive for these families to use LPG regularly instead of sporadically. Priority households for Ujjwala, especially those with no working age adults, are often severely economically disadvantaged and can’t afford to buy LPG at regular intervals.
Furthermore, unlike LPG, a traditional mud stove is more versatile and can serve dual purposes of space heating and cooking during winter months. Many prospective customers are also hesitant about the inferior taste of food cooked in LPG, the utility of the mud stove’s smoke as insect repellent, and the trade-off of expenses on tobacco and alcohol with LPG refills.
As per past studies, even the richest 10% of India’s rural households (most with access to LPG) continue to depend on solid fuels to meet ~50% of their cooking energy demand. This suggests that wealth is not the only stumbling block in the transition process.
“Whatever factors matter in the outside world, my working hypothesis is that every decision is finally mediated through a person’s attitude, knowledge, and perceptions of control,” said Kar. According to Kar, interventions can be specifically targeted to address factors that are perceived negatively either by informing people or doing something to improve that factor. Nevertheless, developing effective interventions is no simple task.
Even with a background in physics and management and eight years of experience helping people transition from one technology to another, Kar says he is grateful to have the input of a variety of scholars at IIASA, each with a different perspective and a different set of core skills and experiences. Working in the Energy program alongside IIASA staff and fellow YSSPers from all over the world, Kar puzzles out the unsolved challenge of how to create change for the rural poor.
“That has been one of my drivers, I take it as an intellectual challenge,” said Kar. “Is there a systems approach to the problem?”
For now, Kar is happy if he can return at the end of the day to his family, which he brought with him to Austria during his time as a YSSP participant, feeling like he is opening the door to a vast literature on technology adoption and human behavior, yet untapped in the field of cooking energy access.
“This research is only a very small baby step into trying something different,” said Kar, “I think this sector has so many unanswered questions, if I can at least flag that there is a lot of literature out there in other domains and maybe we can use some of it, I think that would be good enough for me.”

In 2007, Sepo Hachigonta was a first-year PhD student studying crop and climate modeling and member of the YSSP cohort. Today, he is the director in the strategic partnership directorate at the National Research Foundation (NRF) in South Africa and one of the editors of the recently launched book Systems Analysis for Complex Global Challenges, which summarizes systems analysis research and its policy implications for issues in South Africa.

But the YSSP program is what first planted the seed for systems analysis thinking, he says, with lots of potential for growth.
Through his YSSP experience, Hachigonta saw that his research could impact the policy system within his home country of South Africa and the nearby region, and he forged lasting bonds with his peers. Together, they were able to think broadly about both academic and cultural issues, giving them the tools to challenge uncertainty and lead systems analysis research across the globe.
Afterwards, Hachigonta spent four years as part of a team leading the NRF, the South African IIASA national member organization (NMO), as well as the Southern African Young Scientists Summer Program (SA-YSSP), which later matured into the South African Systems Analysis Centre. The impressive accomplishments that resulted from these programs deserved to be recognized and highlighted, says Hachigonta, so he and his colleagues collected several years’ worth of research and learning into the book, a collaboration between both IIASA and South African experts.
“After we looked back at the investment we put in the YSSP, we had lots of programs that were happening in South Africa, and lots of publications and collaboration that we wanted to reignite,” said Hachigonta. “We want to look at the issues that we tackled with system analysis as well as the impact of our collaborations with IIASA.”
Now, many years into the relationship between IIASA and South Africa, that partnership has grown.
Between 2012 and 2015, the number of joint programs and collaborations between IIASA and South Africa increased substantially, and the SA-YSSP taught systems analysis skills to over 80 doctoral students from 30 countries, including 35 young scholars from South Africa.
In fact, several of the co-authors are former SA-YSSP alumni and supervisors turned experts in their fields.
“We wanted to use the book as a barometer to show that thanks to NMO public entity funding, students have matured and developed into experts and are able to use what they learned towards the betterment of the people,” says Hachigonta. The book is localized towards issues in South Africa, so it will bring home ideas about how to apply systems analysis thinking to problems like HIV and economic inequality, he adds.
“It’s not just a modeling component in the book, it still speaks to issues that are faced by society.”
Complex social dilemmas like these require clear and thoughtful communication for broader audiences, so the abstracts of the book are organized in sections to discuss how each chapter aligns systems analysis with policymaking and social improvement. That way, the reader can look at the abstract to make sense of the chapter without going into the modeling details.
“Systems analysis is like a black box, we do it every day but don’t learn what exactly it is. But in different countries and different sectors, people are always using systems analysis methodologies,” said Hachigonta, “so we’re hoping this book will enlighten the research community as well as other stakeholders on what systems analysis is and how it can be used to understand some of the challenges that we have.”
“Enlightenment” is a poetic way to frame their goal: recalling the age of human reason that popularized science and paved the way for political revolutions, Hachigonta knows the value of passing down years of intellectual heritage from one cohort of researchers to the next.
“You are watching this seed that was planted grow over time, which keeps you motivated,” says Hachigonta.
“Looking back, I am where I am now because of my involvement with IIASA 11 years ago, which has been shaping my life and the leadership role I’ve been playing within South Africa ever since.”
