Building trust in trade deals – is human rights monitoring the answer?

Building trust in trade deals – is human rights monitoring the answer? 27 May 2021 — 4:00PM TO 5:15PM Anonymous (not verified) 14 May 2021 Online

Exploring the arguments in favour of more robust human rights monitoring systems and why effective monitoring mechanisms have proved so difficult to get up and running.

The recent signing of the EU-China Investment Agreement has reignited arguments about trade and human rights. While many trade agreements envisage human rights monitoring in some shape or form, the monitoring systems that have emerged so far are not especially coherent, systematic or impactful. 

Are the human rights commitments in trade agreements more than just window-dressing?  If so, what kind of monitoring is needed to ensure they are lived up to? 

At this panel event, which marks the launch of a new Chatham House research paper, participants explore the arguments in favour of more robust human rights monitoring systems and why effective monitoring mechanisms have proved so difficult to get up and running in this context. 

  • What factors are presently holding governments back, and where is innovation and investment most needed?
  • What are the political, economic and structural conditions for fair and effective human rights monitoring of trade agreements? 
  • Is human rights monitoring best done unilaterally – or should more effort be put into developing joint approaches? 
  • What role might human rights monitoring have to play in governments’ strategies to ‘build back better’ from the COVID-19 pandemic?

Monitoring of trade deals needs a risk-based approach

Monitoring of trade deals needs a risk-based approach Expert comment NCapeling 24 May 2021

On human rights issues, trading partners must do more than trust to luck.

The recent row within the UK government about the treatment of agricultural products in a proposed new trade deal with Australia provides a reminder that changes to trading arrangements can have social and environmental costs, as well as benefits.

Although the UK government clearly feels political pressure to demonstrate its ‘Global Britain’ credentials with some speedily concluded new deals, rushing ahead without a full understanding of the social, environmental, and human rights implications risks storing up problems for later. In the meantime, calls for better evaluation and monitoring of trade agreements against sustainability-related commitments and goals – ideally with statutory backing – will only get stronger.

EU experiences with these kinds of processes are instructive. For more than 20 years the Directorate General for Trade of the European Commission (DG Trade) has been commissioning sustainability impact assessments (SIAs) from independent consultants in support of trade negotiations, and since 2012 these assessments have explicitly encompassed human rights impacts as a core part of the analysis.

The Commission should be transparent about how it plans to respond to the EU-Mercosur SIA recommendations regarding flanking measures and follow up

These processes have since been augmented with a programme of periodic ‘ex post’ evaluations of trade agreements to ‘analyse the observed economic, social, human rights, and environmental impacts’ of live trade deals and to make recommendations about any mitigation action which may be needed.

For credibility and objectivity, the Commission outsources much of its sustainability assessment and ex post evaluation activities to independent consultants, who are encouraged to innovate and tailor their approaches subject to broad methodological parameters laid down by the Commission. Over time, experiences with specific assessment and monitoring assignments have enabled external SIA practitioners – and the Commission itself – to progressively strengthen these processes and underlying methodologies.

Yet despite the improvements there remains legitimate questions about whether the human rights aspects of these SIA processes – and subsequent evaluations – are having real policy impact. The difficulty of predicting human rights impacts of trade agreements in advance – as the COVID-19 crisis amply demonstrates – suggests a need for realism about the extent to which a ‘one off’ process, often carried out at a time when there is only ‘agreement in principle’ as to future trading terms, can produce a robust roadmap for heading off future human rights-related risks.

Human rights impact assessments have a potentially valuable role to play in laying down the substantive and structural foundations for future human rights monitoring as part of a broader, iterative, human rights risk management strategy. But the fragmented manner in which many trade agreements approach human rights issues, and the fact that outcomes are the product of negotiation rather than necessarily design, make it difficult to turn this vision into reality.

Controversies surrounding the SIA process for the EU-Mercosur agreement illustrate why striving for more coherence in the identification and subsequent management of human rights-related risks is important. In June 2019, the Commission decided to wrap up negotiations with the South America Mercosur bloc, even though the SIA process for the proposed agreement was still incomplete and the interim and final SIA reports yet to be delivered. Frustrated NGOs made their feelings clear in the form of a formal complaint – and a slap on the wrist from the EU Ombudsman duly followed.

While there may be opportunities for EU institutions to follow up the recommendations through unilateral ex post evaluation processes, current legal, policy, and institutional arrangements provide few guarantees this will take place

However, when it eventually appeared in December 2020, the final SIA report for the EU-Mercosur deal did include a number of interesting recommendations for responding to specific areas of human rights-related risk identified through the pre-signing assessment process – such as flanking measures designed to address issues pertaining to health, equality, and protection of indigenous peoples, and stressing the need for ‘continuous monitoring’.

Hopefully these recommendations will be proactively followed up, but there are reasons not to be overly optimistic about that. To the extent that these recommendations might have required, or benefitted from, some tweaks to the terms of the trade agreement itself, it was clearly too late. And while there may be opportunities for EU institutions to follow up the recommendations through unilateral ex post evaluation processes, current legal, policy, and institutional arrangements provide few guarantees this will take place.

The credibility of the EU SIA programme has clearly taken a knock because of the problems with the EU-Mercosur process, and stakeholders could be forgiven for questioning whether expending time and effort on engaging in these processes is actually worthwhile. As a first step towards rectifying this, the Commission should be transparent about how it plans to respond to the EU-Mercosur SIA recommendations regarding flanking measures and follow up – ideally consulting with stakeholders about the various human rights monitoring options available.

Looking further ahead, the Commission should be urging SIA practitioners to deal more expansively with the options for follow up human rights monitoring in future SIA reports, setting out recommendations not just on the need for ongoing monitoring of human rights-related issues but on the detail of how this might be done, and how progress towards human rights-related goals could be tracked. And creativity should be encouraged because, as detailed in a newly-published Chatham House research paper, there may be more opportunities for human rights monitoring than first appear.

The SIA process could also provide a forum for exploring complementary measures needed to make future monitoring efforts as effective as possible – jointly and unilaterally; politically, structurally, and resources-wise; both within the framework of the trading relationship and extraneously. The credibility of the process – and hence stakeholder trust – would be further enhanced by commitments from the Commission to be more transparent in future about how different human rights monitoring recommendations laid out in SIAs have been taken into account in subsequent negotiations, in the supervisory arrangements developed for specific trading relationships, and in the implementation of EU trade policy more generally.

Sand: Monitoring and management for a sustainable future

Sand: Monitoring and management for a sustainable future 2 March 2021 — 1:00PM TO 2:00PM Anonymous (not verified) 18 February 2021 Online

In partnership with the Global Sand Observatory Initiative, this event outlines the sand challenge, what actions are currently underway to address it, and what else needs to be done.

Please complete your registration on Zoom:

After water, sand is the raw material that the world consumes in the greatest quantity. It is no exaggeration to say that fine sand and coarser materials – the medium-to-coarse-grained pebbles, gravel and rock fragments used in construction – are the building blocks of the modern world.

When bound with cement, sand becomes concrete; when mixed with bitumen, it becomes asphalt; and when heated, it becomes glass. Without sand, we would have no highways, high-rises or high-speed trains. Yet sand – which is used here as shorthand for sand, gravel and crushed rock together – is a resource that is both abundant and finite.

In global terms, it is abundant, especially when compared with many other raw materials, albeit often not available close to where it is needed. It is finite in that the rate at which we are using it far exceeds the natural rate at which it is being replenished by the weathering of rocks by wind and water.

Industrialization, population growth and urbanization have fuelled explosive growth in the demand for sand. Precise data on sand extraction are hard to come by and the lack of data compounds the challenge of managing the resource sustainably.

However, the UN estimates that overall extraction could be in the region of 40 billion tonnes per year, driven primarily by construction sector demand. That equates to 18 kilograms of sand each day for every person on the planet and signals how strategically important these resources are for future sustainable development. Post-COVID-19 recovery investment in infrastructure, digital technologies, tourism and other economic activities are dependent on sand resources.

Current efforts to improve the management of sand resources at local, national and global levels are uneven. This is partly due to unique geological features and geography, but also differences in local manifestations of the ‘sand challenge’, national and regional demand for sand resources, as well as capacities to enforce or implement best practice assessment procedures, extractive practices, environmental management and restoration requirements.

We must put stronger conditions in place for a rapid, just and scaled transition to sustainable sand management. But where to focus our efforts for the greatest positive impact?

Clearer Role for Business Regulators Needed in Monitoring Trade Agreements

6 July 2020

Dr Jennifer Ann Zerk

Associate Fellow, International Law Programme
As the economic recovery from coronavirus is worked through, careful steps are needed to ensure actions to enforce human rights commitments in trade agreements do not worsen human rights impacts.

2020-07-06-Cambodia-Workers-Rights

Trade policy is a blunt instrument for realizing human rights. Although many trade agreements now include commitments on human rights-related issues - particularly labour rights - not everyone agrees that linking trade to compliance with human rights norms is appropriate, let alone effective.

Sceptics point out that such provisions may become an excuse for interference or ‘disguised protectionism’ and admittedly anyone would be hard-pressed to identify many concrete improvements which can be directly attributed to social and human rights clauses in trade agreements.

This lack of discernible impact has a lot to do with weak monitoring and enforcement. A more fundamental problem is the tendency of trading partners to gloss over – both in the way that commitments are framed and in subsequent monitoring efforts – significant implementation gaps between the standards states sign up to, and the reality.

Working from ‘baseline’ international standards and treating each state’s human rights treaty ratification record as an indicator of compliance does offer objective verifiability. But it also means underlying economic, structural, cultural, social, and other problems, often go unidentified and unaddressed in the trading relationship.

Regulatory failings of trading partners

Those with sufficient leverage can use dispute resolution or enforcement proceedings to signal displeasure at the regulatory failings of their trading partners, as recently shown by the European Commission (EC) in relation to labour violations by trading partners – against South Korea under the 2011 EU-South Korea Free Trade Agreement (FTA) and Cambodia under the EU’s Generalised Scheme of Preferences (GSP) scheme.

These actions do show a more proactive and rigorous EU approach to monitoring and enforcement and have been largely welcomed – especially by trade unions – as a necessary political response to persistent failings by the states to address violations of fundamental labour rights. However, claiming any major victories on behalf of the workers who produce the goods being traded seems premature.

The ‘implementation gaps’ - between human rights commitments made in a state-to-state context and the reality of the human rights situation on the ground - mean there may be cases where enforcement action under a trading arrangement, such as the removal of trade preferences, may actually make things worse. Some local unions have expressed concern that the EU action against Cambodia may be detrimental to vulnerable migrant women factory workers, especially in the context of a worsening economic situation due to the pandemic.

Making stakeholder voices heard

There are routes through which people with first-hand knowledge of human rights-related problems arising from trading relationships – such as labour rights abuses in global supply chains – can make their voices heard. Unions have used consultative bodies set up under trade agreements to highlight labour abuses in trading partner countries - this helped to shift the Commission’s strategy towards South Korea.

But the rather vague and open-ended mandates of these consultative bodies, and their reliance on cash-strapped civil society organisations to do much of the heavy lifting, means they are not a solid basis for systematic follow-up of human rights problems.

And yet, every country is likely to have a number of agencies with interests and expertise in these issues. Beyond labour inspectorates, this could include environmental regulators, licensing bodies, ombudsmen, national healthcare bodies, special-purpose commissions, ‘responsible business’ oversight and certification bodies, local government authorities and national human rights institutions.

At present these groups are barely mentioned in trade agreements with monitoring frameworks for human rights. And if they do feature, there tends to be little in the agreement terms to guarantee their participation.

To seriously address implementation gaps, there needs to be much greater and more systematic use of these domestic regulatory bodies in human rights monitoring and enforcement activities. These bodies are potentially vital sources of information and analysis about the many different social, economic, environmental and human rights consequences of trade, and can also contribute to designing and delivering ‘flanking measures’ needed to assist with the mitigation of human rights-related risks or adverse impacts which have been detected.

Looking further ahead, monitoring practitioners may find - as those involved in the EU GSP+ scheme have already noticed - that close and visible engagement with domestic regulatory bodies helps strengthen a regulator in getting clearer political support and better resources. It can also help with greater ‘buy-in’ to human rights reform agendas, creating conditions for a positive legacy in the form of more confident, committed, and capable domestic regulatory bodies.

Paying more attention to synergies that exist between the work of domestic regulatory bodies and the principles and objectives which cause states to seek human rights commitments from their trading partners is a vital contribution to the concept of ‘building back better’ from the present crisis.

The goal should be to move from the present system – which veers between largely ineffective consultative arrangements and adversarial, often high stakes, dispute resolution – to more cooperative and collaborative systems which draw more proactively from the knowledge and expertise of domestic regulatory bodies, not only in the identification and monitoring of risks, but also in the delivery of jointly agreed strategies to address them.

Quantitative profiling of protein tyrosine kinases in human cancer cell lines by multiplexed parallel reaction monitoring assays [Technology]

Protein tyrosine kinases (PTKs) play key roles in cellular signal transduction, cell cycle regulation, cell division, and cell differentiation. Dysregulation of PTK-activated pathways, often by receptor overexpression, gene amplification, or genetic mutation, is a causal factor underlying numerous cancers. In this study, we have developed a parallel reaction monitoring (PRM)-based assay for quantitative profiling of 83 PTKs. The assay detects 308 proteotypic peptides from 54 receptor tyrosine kinases and 29 nonreceptor tyrosine kinases in a single run. Quantitative comparisons were based on the labeled reference peptide method. We implemented the assay in four cell models: 1) a comparison of proliferating versus epidermal growth factor (EGF)-stimulated A431 cells, 2) a comparison of SW480Null (mutant APC) and SW480APC (APC restored) colon tumor cell lines, and 3) a comparison of 10 colorectal cancer cell lines with different genomic abnormalities, and 4) lung cancer cell lines with either susceptibility (11-18) or acquired resistance (11-18R) to the epidermal growth factor receptor tyrosine kinase inhibitor erlotinib. We observed distinct PTK expression changes that were induced by stimuli, genomic features or drug resistance, which were consistent with previous reports. However, most of the measured expression differences were novel observations. For example, acquired resistance to erlotinib in the 11-18 cell model was associated not only with previously reported upregulation of MET, but also with upregulation of FLK2 and downregulation of LYN and PTK7. Immunoblot analyses and shotgun proteomics data were highly consistent with PRM data. Multiplexed PRM assays provide a targeted, systems-level profiling approach to evaluate cancer-related proteotypes and adaptations. Data are available through Proteome eXchange Accession PXD002706.

Clinician-Reported Barriers and Needs for Implementation of Continuous Glucose Monitoring

Background:

Continuous glucose monitoring (CGM) for patients with type 1 and type 2 diabetes is associated with improved clinical, behavioral, and psychosocial patient health outcomes and is part of the American Diabetes Association’s Standards of Medical Care. CGM prescription often takes place in endocrinology practices, yet 50% of adults with type 1 diabetes and 90% of all people with type 2 diabetes receive their diabetes care in primary care settings. This study examined primary care clinicians’ perceptions of barriers and resources needed to support CGM use in primary care.

Methods:

This qualitative study used semistructured interviews with primary care clinicians to understand barriers to CGM and resources needed to prescribe. Participants were recruited through practice-based research networks. Rapid qualitative analysis was used to summarize themes from interview findings.

Results:

We conducted interviews with 55 primary care clinicians across 21 states. Participants described CGM benefits for patients with varying levels of diabetes self-management and engagement. Major barriers to prescribing included lack of insurance coverage for CGM costs to patients, and time constraints. Participants identified resources needed to foster CGM prescribing, for example, clinician education, support staff, and EHR compatibility.

Conclusion:

Primary care clinicians face several challenges to prescribing CGM, but they are interested in learning more to help them offer it to their patients. This study reinforces the ongoing need for improved clinician education on CGM technology and continued expansion of insurance coverage for people with both type 1 and type 2 diabetes.

Analysis of Sleep and Circadian Rhythms from Drosophila Activity-Monitoring Data Using SCAMP

Sleep is a fundamental feature of life for virtually all multicellular animals, but many questions remain about how sleep is regulated and what biological functions it plays. Substantial headway has been made in the study of both circadian rhythms and sleep in the fruit fly Drosophila melanogaster, much of it through studies of individual fly activity using beam break counts from Drosophila activity monitors (DAMs). The number of laboratories worldwide studying sleep in Drosophila has grown from only a few 20 years ago to hundreds today. The utility of these studies is limited by the quality of the metrics that can be extracted from the data. Many software options exist to help analyze DAM data; however, these are often expensive or have significant limitations. Therefore, we describe here a method for analyzing DAM-based data using the sleep and circadian analysis MATLAB program (SCAMP). This user-friendly software has an advantage of combining several analyses of both sleep and circadian rhythms in one package and produces graphical outputs as well as spreadsheets of the outputs for further statistical analysis. The version of SCAMP described here is also the first published software package that can analyze data from multibeam DAM5Ms, enabling determination of positional preference over time.

Activity Monitoring for Analysis of Sleep in Drosophila melanogaster

Sleep is important for survival, and the need for sleep is conserved across species. In the past two decades, the fruit fly Drosophila melanogaster has emerged as a promising system in which to study the genetic, neural, and physiological bases of sleep. Through significant advances in our understanding of the regulation of sleep in flies, the field is poised to address several open questions about sleep, such as how the need for sleep is encoded, how molecular regulators of sleep are situated within brain networks, and what the functions of sleep are. Here, we describe key findings, open questions, and commonly used methods that have been used to inform existing theories and develop new ways of thinking about the function, regulation, and adaptability of sleep behavior.

Microneedle Glucose Sensors Keep Monitoring Skin-Deep



For people with diabetes, glucose monitors are a valuable tool to monitor their blood sugar. The current generation of these biosensors detect glucose levels with thin, metallic filaments inserted in subcutaneous tissue, the deepest layer of the skin where most body fat is stored.

Medical technology company Biolinq is developing a new type of glucose sensor that doesn’t go deeper than the dermis, the middle layer of skin that sits above the subcutaneous tissue. The company’s “intradermal” biosensors take advantage of metabolic activity in shallower layers of skin, using an array of electrochemical microsensors to measure glucose—and other chemicals in the body—just beneath the skin’s surface.

Biolinq just concluded a pivotal clinical trial earlier this month, according to CEO Rich Yang, and the company plans to submit the device to the U.S. Food and Drug Administration for approval at the end of the year. In April, Biolinq received US $58 million in funding to support the completion of its clinical trials and subsequent submission to the FDA.

Biolinq’s glucose sensor is “the world’s first intradermal sensor that is completely autonomous,” Yang says. While other glucose monitors require a smartphone or other reader to collect and display the data, Biolinq’s includes an LED display to show when the user’s glucose is within a healthy range (indicated by a blue light) or above that range (yellow light). “We’re providing real-time feedback for people who otherwise could not see or feel their symptoms,” Yang says. (In addition to this real-time feedback, the user can also load long-term data onto a smartphone by placing it next to the sensor, like Abbott’s FreeStyle Libre, another glucose monitor.)

More than 2,000 microsensor components are etched onto each 200-millimeter silicon wafer used to manufacture the biosensors.Biolinq

Biolinq’s hope is that its approach could lead to sustainable changes in behavior on the part of the individual using the sensor. The device is intentionally placed on the upper forearm to be in plain sight, so users can receive immediate feedback without manually checking a reader. “If you drink a glass of orange juice or soda, you’ll see this go from blue to yellow,” Yang explains. That could help users better understand how their actions—such as drinking a sugary beverage—change their blood sugar and take steps to reduce that effect.

Biolinq’s device consists of an array of microneedles etched onto a silicon wafer using semiconductor manufacturing. (Other glucose sensors’ filaments are inserted with an introducer needle.) Each chip has a small 2-millimeter by 2-millimeter footprint and contains seven independent microneedles, which are coated with membranes through a process similar to electroplating in jewelry making. One challenge the industry has faced is ensuring that microsensors do not break at this small scale. The key engineering insight Biolinq introduced, Yang says, was using semiconductor manufacturing to build the biosensors. Importantly, he says, silicon “is harder than titanium and steel at this scale.”

Miniaturization allows for sensing closer to the surface of the skin, where there is a high level of metabolic activity. That makes the shallow depth ideal for monitoring glucose, as well as other important biomarkers, Yang says. Due to this versatility, combined with the use of a sensor array, the device in development can also monitor lactate, an important indicator of muscle fatigue. With the addition of a third data point, ketones (which are produced when the body burns fat), Biolinq aims to “essentially have a metabolic panel on one chip,” Yang says.

Using an array of sensors also creates redundancy, improving the reliability of the device if one sensor fails or becomes less accurate. Glucose monitors tend to drift over the course of wear, but with multiple sensors, Yang says that drift can be better managed.

One downside to the autonomous display is the drain on battery life, Yang says. The battery life limits the biosensor’s wear time to 5 days in the first-generation device. Biolinq aims to extend that to 10 days of continuous wear in its second generation, which is currently in development, by using a custom chip optimized for low-power consumption rather than off-the-shelf components.

The company has collected nearly 1 million hours of human performance data, along with comparators including commercial glucose monitors and venous blood samples, Yang says. Biolinq aims to gain FDA approval first for use in people with type 2 diabetes not using insulin and later expand to other medical indications.
