Restaging Z-Score Debacle
The release of the Z scores for university admission by University Grants Commission (UGC) has brought thousands of complaints and issues from the students, parents, teachers and other stakeholders into discussion. Some others have vowed to take the issue to courts, expecting a fair and just solution.
Most of the complaints are related to the issue of two different cutoff Z scores for new syllabus and old syllabus and comparisons thereof. It is understood that the solutions proposed to resolve a crisis must not only be fair and legal but also seen to be reasonable for the stakeholders. Print media during the last couple of weeks published several opinions on this issue and the use of Z score for university admission is often blamed as the reasons for these discrepancies. It is time we had a closer look at the problem and baseless allegations against the use of Z-score for university admission. The use of Z-score in place of aggregated marks of the three subjects is, by all means, a better method, which has been amply demonstrated with data and examples and subjected to discussion since its introduction for university admission in 2003.
There is a diverse degree of variability in nature itself and so it is with the humans and their work. The scientific discipline called statistics provides the conceptual and procedural approaches to understand the variability and manage it fairly and equitably. Due to the inherent variability present in question papers and evaluations, it is very well understood that the simple aggregate obtained from the marks of different subjects is not a fair criterion for determining the eligibility for university admission. The degree of difficulty of the question papers in different subjects varies significantly and also there are variations of the aptitude measurement scale in different years. Therefore, it was not possible to have a fixed cut-off mark or simple aggregate solution to determine eligibility for university admission. For example, marks for one subject could have a range from 5 to 70 while the range for another subject spans from 45 to 99. A student who obtained 70 is the best among the lot in the first case and the one who obtained 70 in the second case is a mediocre student. When the simple aggregate is taken as the criterion for university admission, the best student in the first case is treated equally with the mediocre student who opted for a relatively easy subject as in the second case. Within the general assumption that students who sit for these two different subjects have a more or less equal level of competence, the disparity in the relative difficulty of the question papers or evaluation criteria warrants some sort of an approach for standardization. This issue was the theme for a series of discussions in academic circles and despite several advanced methodologies available for standardization, the Z score approach was adopted about 20 years back as the criterion for university admission due to its simplicity, computational convenience, application efficiency and the need for only two parametric estimates for its calculation.
Today, the issue is somewhat different and it is not possible to assume that the students who sat for two different papers in the same subject are having a more or less equal level of competence or they are random picked from the larger population. The first group has sat for the examination for the first time and the other group has at least attempted to pass the examination on one or more previous occasions. This is evident from the number of the first, second and third attempt students in different disciplines. In exploring a solution to this present problem, the underlying assumptions made in calculating the Z score rankings need to be reexamined. One of the assumptions is that the aptitude of knowledge and skills of the student population opting for different subjects or subject streams are not significantly different. This assumption should be validated now because almost all the students who sat the examination under the old syllabus except those with valid medical or other reasons have made a failed attempt to enter university earlier.
Those who qualify from the new syllabus are a group of students who took the examination for the first time. The assumption of equal knowledge and similar competency level and skill background for these two diverse groups introduces an error into the fair selection process. It is not possible to issue a single series of Z-scores for these two groups. Before processing marks, the hypothesis of statistically non-significant difference between these two student groups needs to be validated with at least past data for a period of 5 years. Since this hypothesis cannot be proved, then the degree of dissimilarity needs to be assessed to determine a fair ratio for university admission from these two groups of students and design a quota for these two groups. This is what the UGC has attempted to employ in the selection process, however, higher differences in the cut-off Z scores due to the impact of quota applied for the two groups has led to serious doubts in the mind of those without an in-depth knowledge of the method.
The second issue is whether the relative difficulty of two questions papers in both old and new syllabi is significantly different. The expert opinion is the only choice we have in this decision. If experts believe that the two sets of questions papers are of more or less a same level of standard, then the two results could have been combined into a single data series with only one set of Z scores and cut-off marks. Unfortunately, there is no evidence to show that this option had been explored by the UGC. If the question papers are at significantly different standards, then it is not possible to combine the two results series. Then the question must be asked from the Department of Examinations why the standards were made to be different and a strong justification for such an action. We always advise our students that they should propose a valid statistical methodology before they collect their data for research to ensure the compatibility of data with the statistical techniques to be employed in the analysis. Unfortunately, the Department of Examinations could not stick to this advice and only seeks a statistically valid solution after collecting the data from student examinations.
Without understanding the pertinent facts, some argue that the mistakes made in 2011/12 university admission have been repeated in releasing the Z-scores for 2019/20 university admission. A similar problem indeed arose in 2011/12 admission due to the release of Z scores, combining the results of students who followed the GCE Advanced level under old and new syllabi. However, in 2011/12 university admission, the major issue was the errors made in the calculation of Z scores by the Department of Examinations. That mistake was further complicated due to the release of a single Z score combining the two distinctly different student populations of old and new syllabi as a single group by the UGC. A presidential expert committee was appointed to look into the problem and the mistake in the calculation was quickly identified and corrected. Besides, the need to consider the two student populations of old and new syllabi separately for university admission was proposed and it was later approved by a Supreme Court judgment in a case filed by a group of aggrieved students.
There are few solutions which could have been adopted to avoid the complexity of the problem and misunderstanding among the students, parents and teachers:
a) The easiest approach would have been the designing one question paper for both groups of students sitting the examination under both old and new syllabi giving options to select questions from the areas that had been revised or amended in the new curriculum. It is observed that there have been no major deviations and only minor changes have been made as regards Physics and Chemistry. The relative difficulty level needs to be maintained across all optional questions. Then, it is a single question paper and a single Z score series generated from the results. This should have been achieved at the point of setting of question papers by the examiners with clear instructions.
b) if the two questions papers, although structurally different, are of the same level of difficulty, the results of the two examinations could have been combined and Z scores computed as a single series.
This solution could have been explained to the Supreme Court and concurrence on this approach sought.
It could have been assumed that although the student populations were different, the same level of tests had been administered for both groups and therefore,
c) The most reasonable solution for the problem is to determine the ratios of students admitted to universities for each subject stream and each degree programme separately for old and new syllabus students, and then for each case use the five-year maximum proportion to admit students to universities. Then the total would exceed one hundred since the maximum of both ratios would exceed 100 and a small proportion of students needs to be admitted to each degree programme to avoid any obvious injustice. The use of median value can also be adopted unless there is a positive or negative trend in the ratios. If the five-year values are stationary and have a low variability among years, this becomes a fair solution. In case the five-year values are having a higher degree of variability and an obvious trend, the most recent value should have been the choice. This method of median value was adopted this year and due to the quota being significantly different for different disciplines and degree programmes, the cut-off Z scores have shown many differences for new and old syllabi students. Also, the cut-off Z-scores are significantly high compared to the figures of the previous years due to the application of quota which sometimes 25% of the original 100. This is the reason for the complaints although the method used for selection is in keeping with the ruling of the Supreme Court in 2012.
However, this problem could have been avoided if the two series of Z scores were adjusted as per the quota granted for each series. A simple mathematical computation could have brought the two distributions on a comparable model. The adjusted Z scores are comparable with the figures of the previous years and it would not produce cut-off Z scores which are much different for students in two groups. The confusion created due to the releasing Z scores indicating a different level of access to university entrance in the two different groups could have been avoided with the help of such an approach.

Now is the time to rethink trade
by Gomi Senadhira
During the presidential election campaign, the importance of trade, particularly exports, to Sri Lanka’s was emphasised by President Anura Kumara Dissanayake (AKD) and the other two main contenders in the fray, namely Sajith Premadasa (SP) and Ranil Wickremesinghe (RW) in their manifestos. These three candidates together polled more than 90 percent of the votes at the presidential elections. During the parliamentary elections the political parties which based their campaign on these manifestos – Jathika Jana Balawegaya (NPP), Samagi Jana Balawegaya (SJB) and New Democratic Front (NDF) together polled more than 83%. Therefore, the electoral support for these pro-trade policies is undisputed. For the Sri Lankan export community this should be a superb development, as for many years, the trade policy had been, one of the more contentious areas of island’s politics. Our main trading partners and the foreign investors would also welcome this policy convergence.
Pro- trade policies in the policy statements of RW and SJ were not unexpected. But the pro-trade approach in the AKD’s manifesto surprised many, mainly because all other parties had repeatedly warned the people against voting for AKD as he would turn Sri Lanka into another North Korea or Cuba.
For example, during the election campaign, at a conference organised by the National Bankers Association, RW stated, “On September 4th, MP Anura Kumara Dissanayake emphasised the importance of focusing on exports for our country’s businessmen and industrialists. While this principle is commendable, there is a concern. Their policy statement suggests that Sri Lanka plans to cancel its free trade agreements.
This raises a significant question: how can we develop an export industry without these agreements? Such contradictions pose challenges.” Since then, he had repeated these comments at several other meetings. In the same way, SP’s trade policy wonks also had spread similar misinformation on NPP policies. However, the NPP policy statement clearly states its position on Free Trade Agreements, that is “… updating of existing free trade agreements and negotiating new free trade agreements.” The updating of the trade agreements certainly does mean cancelling of these agreements. All FTAs need to be reviewed and updated periodically.
During the election seasons, politicians sometimes manipulate public opinion about the crucial issues by arousing fear. But this is not the time to deliberately mislead the public in general and, more particularly, the business community and our trading partners with false information on trade policy. At this juncture, what we need are facts. Not scare tactics and false information. So, let’s hope our politicians would avoid such scare tactics in the future and join together to strengthen this consensus on export-oriented, outward-looking trade policy.
To those who are familiar with the way the NPP policies evolved in the recent past, their shift towards pro-trade policies is not a surprise. After all, if the NPP and AKD want a socialist model to emulate, they have many examples of socialist governments, other than North Korea and Cuba, to draw lessons from. For example, the success story of the Socialist Republic of Vietnam. While cautiously staying away from the labels AKD’s policy statement refers to Vietnam, Bangladesh, and South Korea (and not North Korea) as export success stories, Sri Lanka can acquire lessons from. More importantly, Vietnam’s success story was also highlighted at the top of RW’s policy statement and by the trade experts in the SJB as a success story to follow. What is needed now is to strengthen this consensus further and develop a pro-export national trade strategy approved by the parliament. That would help to attract much-needed foreign investments and export orders.
If we already have a general consensus on pro-trade and pro-export policies, then why do we need to rethink trade policies now?
From export-oriented economy to import dependent economy
Sri Lanka was the first country in South Asia to liberalise trade policies with the ‘open’ economy introduced in the late 1970s. However, the open economy introduced then was not fully open. It had a strong focus on the expansion of the export of goods while discouraging imports, particularly nonessential imports. A special cess was imposed on the nonessential imports to protect local farmers and manufacturers and to collect funds for export development.
The main thrust of the trade policy was exports. During that period, the government proactively managed to get an adequate level of market access to Sri Lankan exports through multilateral trade rules (GATT/WTO rules) as well as the distortions to those rules (textile quotas). These policies worked well, and during the 1980s and 90s, Sri Lanka’s exports registered almost a fivefold increase, from US$1.35 billion in 1981 to US$6.37 billion by the year 2000. The exports-to-GDP ratio increased from 30.46% in 1981 to 39.02% in 2000. During the period, Sri Lanka was slowly but surely progressing into an export-oriented economy.
Unfortunately, during the next two decades, the export growth slowed down and only increased from US$6.37 billion (in 2000) to US$13.03 billion (in 2020). The exports-to-GDP ratio also declined substantially during this period. At 15.46% in 2020, it was the lowest ever recorded. More alarmingly, the growth of exports during the last decade was almost stagnant, and it increased only from US$ 10 billion in 2013 to US$ 12 billion in 2023. During the same period, Vietnam’s exports increased from US$132 billion in 2013 to US$370 billion in 2023.
Hijacking of trade policy by importers and profiteers
The main reason for this decline was the absence of interest in export development by the successive governments and the influence of the importers, the profiteers and perhaps even hawaladars on trade policy formulations. If one analyses the trade policy formulation in the recent years, it is easy to understand how trade policies and even free trade agreements were directed towards import promotion at the expense of export development. After signing Sri Lanka’s first bilateral FTA with India in December 1998 and second with Pakistan in August 2002, and the enhanced GSP arrangement in the EU, no new tangible initiatives were taken by the government to develop market access for Sri Lankan exports.
During the last decade the situation deteriorated further and even the free trade agreements, which countries normally negotiate at the request and on behalf of their exporters to get better levels of market access for them in other countries, were negotiated at the request of the exporters of other countries to provide them with enhanced market access into Sri Lanka without reciprocal concessions for Sri Lankan exporters. The free trade agreements Sri Lanka signed with Singapore and Thailand are clear examples of this approach.
These agreements were negotiated under RW’s leadership, first as the prime minister and then as the president. Despite his rhetoric about the critical need to swiftly transform Sri Lanka into an export-oriented economy, as stabilising the economy alone would not solve Sri Lanka’s problems due to the country’s heavy dependence on imports, it was under RW’s leadership that the trade policy got blatantly hijacked by the importers mafia and profiteers.
Another adverse development during the last two decades was the relaxation of foreign exchange regulations. Due to this Sri Lanka also does not fully benefit even from the limited amount of exports, as a substantial portion of the export proceeds are not repatriated. In July 2022 the Central Bank revealed that less than 20% of export proceeds are being repatriated by the exporters. Though this may have improved since then, the conversion rate remains below accepted levels. In addition to that, a significant amount of money is transferred out through trade misinvoicing by the exporters and importers.
As the elections are over now it is the time for a new beginning. It is the time to intensify analysis and advocacy regarding the numerous ways that trade agreements and po8licies must be reformed and strengthen the consensus on trade policies and adjust them to undo decades of capture by the importers’ mafia, profiteers, and hawaladars.

Navigating Sri Lanka’s economic recovery: Opportunities and risks in the aftermath of Cyclone Fengal
by Prof. Chanaka Jayawardhena,
Professor of Marketing, University of Surrey, UK.
Chanaka.j@gmail.com
Sri Lanka finds itself at a crossroads. The devastation caused by Cyclone Fengal, which displaced over half a million people, destroyed critical infrastructure, and claimed numerous lives, highlights the country’s vulnerability to natural disasters. At the same time, the nation is tentatively emerging from its first-ever sovereign debt default, buoyed by a $12.5 billion bond swap and an IMF bailout. Together, these events pose an urgent question: Can Sri Lanka navigate the treacherous path of recovery without derailing its fragile economic stability?
The answer lies in the delicate balance the government must strike. Cyclone Fengal is more than just a natural disaster—it is a stress test for the economic goodwill painstakingly built up over the past year. How Sri Lanka’s policymakers respond could define the trajectory of its recovery for years to come. This is not just about reconstruction; it is about rethinking priorities, leveraging the current crisis as an opportunity to build resilience, and ensuring the hard-won economic gains are not squandered in the process.
Cyclone Fengal: A Catalyst for Change or a Step Backward?
The immediate economic impact of Cyclone Fengal is staggering. Agriculture, one of the backbones of Sri Lanka’s economy, has suffered significant losses, with thousands of acres of paddy fields and tea plantations—critical export sectors—being submerged. Damaged transport networks have disrupted supply chains, delaying the movement of goods and escalating costs for businesses and consumers alike. The government now faces the twin challenges of financing disaster relief and rebuilding vital infrastructure, all within the constraints of a tight fiscal envelope.
The human cost is equally dire. Families have lost homes, livelihoods, and loved ones. The socio-economic fallout of such displacement is long-lasting, with vulnerable communities pushed further into poverty. Moreover, the environmental damage, including soil erosion and the destruction of ecosystems, adds another layer of complexity to recovery efforts.
Yet, there is an opportunity amidst this tragedy. Disasters often serve as catalysts for long-overdue reforms. Cyclone Fengal could prompt Sri Lanka to implement policies aimed at climate resilience, investing in infrastructure that can withstand future storms and floods. Such investments would not only protect lives and livelihoods but also reduce the economic disruptions caused by such events. However, realising this opportunity requires vision, coordination, and a clear commitment to long-term planning—qualities that have not always been hallmarks of Sri Lankan governance.
The risks, however, are equally pronounced. With limited fiscal space and the need to adhere to IMF conditionalities, there is a real danger that recovery efforts might siphon funds away from critical economic reforms. If mismanaged, this could erode investor confidence, putting at risk the progress made in stabilising the economy. The government must guard against the temptation to prioritise short-term relief over the long-term restructuring that is vital for sustainable growth.
Debt Restructuring: The Elephant in the Room
Sri Lanka’s recent $12.5 billion bond swap was a bold move to address its debt crisis, but the relief it offers is conditional. Investors and international institutions are closely watching how the government navigates its commitments to fiscal discipline and structural reform. Cyclone Fengal has now added an unexpected layer of complexity to this equation.
The IMF bailout, which released $333 million in its latest tranche, demands not only fiscal prudence but also tangible progress in revenue generation and state enterprise restructuring. These measures, while necessary, are politically sensitive and require a stable economic environment to succeed. The cyclone’s aftermath threatens to upset this balance, with rising expenditure on disaster relief potentially crowding out these reforms.
Moreover, the bond swap itself is not without controversy. While it offers breathing room, it also raises questions about the sustainability of Sri Lanka’s debt strategy. With global interest rates on the rise, the cost of future borrowing could escalate, particularly if the government fails to demonstrate fiscal discipline. In this context, the pressure to deliver results has never been greater. Successfully managing this dual challenge of recovery and reform will be the ultimate test of Sri Lanka’s political and economic leadership.
Lessons from other economies
Sri Lanka is not the first country to face the dual challenge of disaster recovery and economic reform. Indonesia’s response to the 2004 tsunami offers valuable lessons. By channelling international aid into long-term development projects and maintaining fiscal discipline, Indonesia turned a crisis into an opportunity for economic transformation. Key to its success was the establishment of a dedicated reconstruction agency that ensured transparency and accountability in the use of funds.
Bangladesh, another country prone to natural disasters, has demonstrated how investing in disaster preparedness—through early warning systems, robust infrastructure, and community education—can mitigate economic losses. These measures have not only saved lives but also reduced the financial impact of natural disasters, enabling the economy to recover more quickly.
Sri Lanka would do well to follow these examples. The establishment of a specialised disaster management authority with a clear mandate and adequate funding could go a long way in ensuring a coordinated and effective response. Such an agency could also play a critical role in securing international aid, which is often contingent on transparent governance and accountability. Ensuring such mechanisms are in place will be crucial to sustaining international goodwill and ensuring long-term economic stability.
Investing in Resilience
The case for strategic investment in resilience is clear. Renewable energy projects, for instance, could reduce the country’s reliance on costly fuel imports while aligning with global sustainability trends. Sri Lanka’s abundant natural resources—sunlight, wind, and hydro potential—position it well to transition to a greener energy mix. Such investments would not only lower energy costs but also make the economy less vulnerable to global fuel price shocks.
Rebuilding transport and communication networks with a focus on durability would also yield significant benefits. Modern, resilient infrastructure is essential for economic growth, facilitating trade, tourism, and investment. Furthermore, the construction phase itself could create jobs, providing a much-needed stimulus to the domestic economy.
Public health must also be a priority. The cyclone has triggered a surge in dengue cases, exposing gaps in the healthcare system’s ability to respond to emergencies. Strengthening healthcare infrastructure and preventive measures could yield significant economic and social dividends. Healthier populations are more productive, and the costs of prevention are far lower than those of treatment and lost productivity.
Building on Goodwill
Sri Lanka enters this challenging phase with a degree of goodwill that is rare for a country emerging from economic collapse. The Central Bank’s policy rate reforms and the government’s efforts to stabilise public finances have been cautiously welcomed by investors. Moody’s recent decision to place Sri Lanka’s credit rating under review for a potential upgrade reflects this optimism.
However, goodwill is a finite resource. The government must tread carefully, avoiding populist measures that could derail its reform agenda. Transparency in disaster relief spending and clear communication about the trade-offs involved in balancing recovery with reform are essential. Failure to do so could erode the trust of both domestic and international stakeholders.
The risk of political complacency is real. The government’s recent electoral mandate, while overwhelming, should not be taken as a licence to abandon fiscal prudence. Populist policies, such as unsustainable subsidies or tax cuts, could undo the progress made and jeopardise long-term stability.
A Path Forward
Cyclone Fengal has exposed the vulnerabilities in Sri Lanka’s economic and social fabric, but it has also provided an opportunity to address them. The government’s response must be both immediate and strategic, balancing the urgency of disaster relief with the long-term necessity of economic reform.
First, the government must prioritise investments that yield both short-term relief and long-term benefits. For example, rebuilding flood-damaged roads and bridges with climate-resilient materials can create jobs today while reducing costs in the future. Second, it must strengthen institutions to ensure that recovery funds are used effectively and transparently. Third, it must actively engage with international partners, not only for financial support but also for technical expertise in disaster management and economic planning.
Sri Lanka’s recovery is not just a matter of economics; it is a test of governance, competence, and foresight. By investing in resilience, maintaining fiscal discipline, and leveraging international goodwill, the country can navigate this crisis and emerge stronger. The stakes are high, but so are the potential rewards. This is a moment for bold but measured action—a chance to turn adversity into a turning point for sustainable growth.
The eyes of the world are on Sri Lanka. Let this be the moment when it rises to the challenge.

Protecting blue carbon ecosystems, a key to climate resilience
By Ifham Nizam
Blue carbon ecosystems, such as mangroves and sea grasses, are emerging as critical players in global climate mitigation strategies. However, these ecosystems face mounting challenges due to coastal development, climate change, and mismanagement.
Speaking to The Island, renowned expert Dr. Mat Vanderklift, Director of the Indian Ocean Blue Carbon Hub, who is on a short visit to Sri Lanka stressed the urgency of integrating high-integrity principles and sustainable practices to safeguard these vital habitats.
Excerpts of the interview
Q: Dr. Can you elaborate on the unique challenges that blue carbon ecosystems, such as mangroves and sea grasses, face compared to terrestrial carbon sinks like forests?
A:Mangroves and sea grasses are located on the coastal margins, which places them in areas where many activities occur and competition for space is high. Most people live near coasts, so there are pressures from development as well as infrastructure such as ports. They are also spaces where activities like aquaculture and fishing can lead to degradation if they are not done in a sustainable way.
Q: How do you assess the long-term effectiveness of blue carbon ecosystems in carbon sequestration, especially in the face of climate change impacts like rising sea levels and extreme weather?
A: Mangroves and ecosystems can cope with sea level rise well enough as long as there is space for them to retreat to – although seawalls, roads and other infrastructure can block them. In some places that can simply rise vertically by accumulating sediment. Extreme weather events like heatwaves are a growing problem, and can cause death of vegetation over large areas.
Given the complexities of carbon credit markets, what do you believe are the most promising strategies to ensure that blue carbon credits maintain high environmental integrity? We need to follow principles to ensure that our desire to generate credits does not create further damage or infringe on people’s rights. Principles like doing no harm, respecting rights, empowering people, acting and sharing benefits equitably, and using the best available knowledge. We can follow a ‘mitigation hierarchy’ in which we ensure that we protect first, and restore when we need to.
Q: What role do you see for governments in regulating the emerging market for blue carbon credits to ensure its effectiveness in climate mitigation efforts?”
A: Each government will take a different approach, but some regulation can be helpful. Regulations can help ensure that high integrity principles are followed. Regulations can also help ensure that the right kind of knowledge is generated for a national context. Most nations, including Sri Lanka, have international commitments, and regulation can help make sure that those commitments are realised.
Q: What are some innovative financial models or partnerships that have shown success in attracting private sector investment for the restoration of blue carbon ecosystems?
A: Sometimes we don’t need innovation because the mechanisms already exist, we just need to make them work properly. Carbon and biodiversity markets are an example – they have promise, but are not as successful as they could be because there are barriers to effective implementation.
Q: How can smaller nations or communities with rich blue carbon ecosystems access funding or investment to protect and restore these vital habitats?
A: In some situations, there might be potential to engage with the private sector, and building public-private partnerships can help. These are mostly used for infrastructure projects, but could be harnessed towards climate mitigation and nature protection. In other contexts, some international investment might be needed – the recent climate meeting in Baku finalised some of the international rules under which this can occur.
Q: You mentioned the importance of blue carbon ecosystems for supporting livelihoods, particularly in fisheries and tourism. How can we ensure that the restoration of these ecosystems also benefits local communities economically?
A: This is fundamental, and part of building markets with integrity. Local peoples need to be involved all the way through projects and need to receive an equitable share of benefits. This might mean a share in revenue from the sale of credits, but it might also mean new business or livelihood generation opportunities. If lives are not improved, there will be little support for climate action or nature protection.
What are the potential risks or unintended consequences for coastal communities if blue carbon financing schemes are not properly designed or implemented? In some situations, destructive activities are simply displaced elsewhere, so there is no net benefit. In others, locals do not receive an adequate share of benefits, so trust and long-term success is eroded.
Q: What are some of the key metrics used to assess the health and carbon sequestration potential of blue carbon ecosystems? How reliable are these metrics across different regions?
A: Measuring carbon is relatively easy. Measuring other benefits, such as improvements in fisheries or improved resilience of a community, is much harder but just as important. We need to put more effort into measuring these other benefits.
Q: In terms of monitoring blue carbon projects, what are the most significant technical or logistical challenges that need to be addressed?
A: Cost is often the main barrier. The methods and technologies exist but can be expensive. This can be a barrier in two ways. One is that it makes projects so expensive that revenue from sale of credits does not offset the cost of doing the project. Another is that poorer nations and communities can be left behind. Ensuring that we have low-cost methods that work in developing countries is important for international equity.
Q: As we look to the future, do you think blue carbon credits will become as established and integrated into global carbon markets as terrestrial carbon credits?
A:Yes, they already are. The scale is not as great as it is for forests, but blue carbon credits from the protection and restoration of mangroves and sea grasses are being generated in multiple countries.
Q: How do you envision the evolution of blue carbon and biodiversity financing over the next decade, especially in terms of its role in achieving international climate targets like those in the Paris Agreement?”
A:My aspiration is that we continue to break down the barriers that prevent protection and restoration of blue carbon ecosystems. This can include finance, and developing low-cost technologies and building capacity is key. Just as important will be adoption of high integrity principles and development of an enabling regulatory environment. Some things governments and communities can already do, they just need a little help or a clearer mandate. The emergence of broader nature and biodiversity markets also has potential to reward good ecosystem stewards who are currently locked out of carbon markets.
