Theme: Bringing Fertility Services into Focus: A Forgotten Pillar of Family Planning in Asia

Rationale:

Since 2020, many Asian countries have experienced fertility rates below the replacement level. However, few have incorporated fertility services into their programs to assist infertile couples and enhance overall fertility levels. Additionally, infertility is not widely recognised as a gender issue, and there is limited governmental support to help underprivileged women overcome this challenge. Moreover, infertility remains heavily stigmatised in many Asian societies, particularly for women, impacting their long-term mental health (Unisa, 1999; 2010; Nahar, 2022; Bagade et al., 2022). Limited data on infertility prevalence, poor documentation, and definitional ambiguities have hindered advocacy efforts for infertility services, making them weaker compared to other reproductive health issues (WHO, 2023). Additionally, couples often spend substantial amounts on treatment, and those unable to afford it face significant socio-cultural and psychological challenges (Rozee & Unisa, 2016; Njagi et al.,2023).

Furthermore, infertility diagnosis and treatment are primarily available in private hospitals in many countries. Couples seeking these services often face high out-of-pocket expenses, as government funding does not cover these treatments.  In a few countries with partial services, the out-of-pocket costs can still be significant. Consequently, access to infertility care can be limited for those who cannot afford private healthcare. Therefore, a strategic and unified advocacy effort is needed to drive for better support and funding for infertility treatments, ensuring more equitable access to these essential services.

Aim:

To promote awareness, advocate for policy changes, and collaborate with healthcare providers to improve the accessibility of infertility diagnosis and treatment, while strengthening research and public health integration of fertility services.

Objectives:

  1. To build a collaborative, multidisciplinary network of professionals dedicated to advocating for equitable and ethical fertility care within public health systems.
  2. To raise awareness among policymakers and public health stakeholders about the importance of integrating comprehensive fertility services into national healthcare systems.
  3. To engage and support early-career researchers in investigating the causes, prevalence, and societal impacts of infertility and childlessness.
  4. To provide training for researchers in standardised methodologies for collecting and analysing data on infertility and assisted reproductive technologies (ART).
  5. To examine and compare ART and surrogacy practices across Asian countries, focusing on their accessibility, costs, legal frameworks, and associated socio-psychological dimensions.

 Activities:

  1. Advocacy and Consultation: Create country-specific advocacy papers and conduct national and international consultation meetings with public health officials and program personnel.
  2. Workshops and Webinars: Organise workshops to develop proposals on infertility and ART-related issues, host webinars, and publish an edited book of presented papers.
  3. Public Awareness and Policy Influence: Launch public awareness campaigns via social media, traditional media, and community events, and develop policy briefs and reports to influence policymakers on integrating fertility services into public health systems.
  4. Follow-Up and Sustainability Planning: A regional task force will be developed to follow up after the consultation meeting with policymakers.
  5. Leverage Digital Platforms: Creating an online repository or platform for sharing resources, case studies, and ongoing research to maintain momentum and encourage cross-country collaboration.

Output:

  1. Comprehensive reports and recommendations aimed at policymakers for integrating infertility care into public health systems.
  2. Published studies and datasets analysing infertility prevalence, diagnosis gaps, and treatment accessibility across different demographics.

Outcome:

  1. A well-structured, impactful approach to addressing fertility care and ART-related issues within public health systems.
  2. Comprehensive studies leading to a deeper understanding of infertility trends and influencing global policy discussions.

Policy Use of National Transfer Accounts (NTA) in Ageing Asia 

Objectives

  1. Promote the policy integration of NTA in rapidly ageing Asian countries by aligning outputs with key national policy priorities and strengthening institutional capacity.
  2. Build and strengthen a regional network of NTA practitioners to foster collaboration, facilitate knowledge sharing, and promote regional learning.

The demographic future of Asia demands urgent and informed action. The NTA framework provides essential data and analytical tools to support the development of sustainable, fair, and effective policies. By advancing the policy application of NTA and building a strong regional network, this Scientific Group on NTA (APASG-NTA) aims to help Asian countries respond to the challenges of ageing with resilience and fairness.

Key Activities

  1. Policy Engagement Workshops: Convene NTA teams, policymakers, and international experts to translate data into actionable insights and foster policy dialogue.
  2. Capacity Building: Deliver targeted training for government officials and researchers on the production, interpretation, and application of NTA data.
  3. Policy Briefs and Guidelines: Develop clear, accessible materials to communicate findings and promote integration into national planning and policy frameworks.
  4. Regional Knowledge Exchange Platform: Establish a digital platform featuring a dashboard on policy use of NTA/NTTA/NIA, including summary indicators, methodologies, visualizations, policy briefs, best practices, failure cases, and joint research outputs.
  5. Comparative Studies: Support cross-country research projects to identify regional trends, shared challenges, and effective policy responses across Asia.

Through these activities, the APASG-NTA seeks to institutionalize the NTA framework by working with national agencies to embed NTA into official statistical systems and long-term policy planning processes.

Expected Outcomes

  • Increased policy uptake of NTA in national strategies related to ageing, pensions, and care systems.
  • Improved capacity among policymakers and researchers to collaborate effectively and apply NTA data in policy development.
  • Strengthened regional collaboration through the establishment of a sustained community of practice.
  • Greater visibility and credibility of NTA in both policy and academic spheres, driven by increased awareness of their relevance to policy reforms.
  • Harmonized methodologies and regional benchmarks to support consistent analysis and strategic planning across countries.

Funding

The main funding source for the group's activities will be the jointly provided by the Economic Research Institute for ASEAN and East Asia (ERIA), the Japan National Institute of Population and Social Security Research (IPSS), and the United Nations Population Fund (UNFPA). Additionally, capacity building, policy outreach initiatives, and research projects conducted by ERIA, IPSS and UNFPA will also contribute to some of these activities. The APASG-NTA is also open to contribution in cash or in-kind from other individuals and institutions.

Climate Mobilities, Migrants and Health

 

Rationale:

Numerous studies show that climate change has made a serious impact on the biophysical diversity and the capacity of the ecosystem to provide food, livelihood and health security. As per the IPCC report (2022), the average global surface temperature has increased by over 1 degree C between 2010 and2020 compared to the pre-industrial level. It could rise to 1.5 degrees C by 2040. Scientists repeatedly warn that the world is on a 4-6 degrees C warming pathway, and robust mitigation and adaptation are continuously required.  So far as Asia is concerned the average surface temperature has also been increasing, and this is also very much manifested in increased extreme weather events like droughts, floods, storms and cyclones and the erratic pattern of monsoon in Asia (IPCC, 2022).

People inhibit places that have evolved historically forging deep relationships with their environments. Climate change disrupts the close relationships between people and places, often creating new vulnerabilities and exacerbating the existing ones. While voluntary mobility and migration can reflect the capability to choose where to live or remain, not all movement is voluntary. Climate change often drives forced mobility—through internal displacement, refugee flows, asylum seeking, and even trafficking —undermining people’s ability to exercise agency over their lives. By eroding individual and collective capabilities, climate change threatens to disempower communities and hinder the realisation of social, cultural, economic and political rights. It raises profound concerns for environmental citizenship, reshaping the relationship between people and place through patterns of mobility and migration.  

Climate change is likely to influence mobility and migration in two ways: ‘gradual’ and ‘sudden'. Gradual changes —including increasing aridity, desertification, loss of biodiversity, rising sea level —may prompt voluntary mobility and migration. In contrast, sudden events such as cyclones, floods and severe droughts, may lead to forced mobility, migration and displacement. Yet, such a binary distinction oversimplifies a complex reality. In truth, climate-driven mobility and migration are shaped by an intricate interplay of socio-economic and political factors, where climate change exacerbates pre-existing vulnerabilities rather than acting in isolation.  

This scientific group would work on the premise that climate change should not be seen merely as a biophysical change, but must be viewed as embedded in the socio-economic conditions of affected populations. It means that adaptive capacity varies significantly across communities, and those facing socio-economic disadvantage are most likely to bear the brunt of climate impacts. There is a clear spatial overlap between regions most vulnerable to climate change, areas of deep socio-economic deprivations, and emerging patterns of mobilities and migration across the world, including in Asia.

Livelihoods dependent on agriculture, fisheries, livestock and forestry are increasingly at risk, driving migration as an adaptive strategy. Beyond voluntary migration, rising sea levels and extreme weather events are expected to cause large-scale displacement in both rural and urban areas. This scientific group will examine how these environmental pressures catalyse climate-induced mobility and migration, and identify strategies for mitigation and adaptation.

Importantly, the consequences of climate-related mobility and migration extend far beyond the act of moving. Both areas of origin and destination are likely to experience profound impacts. Health vulnerability is of particular concern, given the increased exposure to extreme weather events such as floods and heatwaves, disruptions to food system, growing water insecurity, and the increased risk of infectious diseases. Accordingly, this scientific group will also address the health outcomes among mobile and vulnerable populations, including those affected by forced displacement and planned relocations.   Through its work, the group will contribute to the development of policies and programmes aimed at achieving climate justice, aligned with the Sustainable Development Goals’ commitment to ‘leave no one behind’.

Aims and Objectives:

  1. Climate change as a driver of mobilities and migrations is embedded with socio-economic and political drivers of migration. How to separate the effects of climate change drivers has been a real challenge of mobility and migration research.
  2. While voluntary (migration by choice) and involuntary movements (displacement and refugees) are often indistinguishable in many circumstances, researchers must take into account the gradual and sudden changes in the form of mobility and migration.
  3. Places of origin and destination, although closely related, methodologically raises questions that need to be addressed differently. While drivers of migration may be important for the areas of origin, the migrants may be relevant to be studied in the places of destination. The separation between the two assumes significance in the study of climate change as a driver and its impact respectively.
  4. Migration and other researchers face enormous challenges so far as secondary data at the areal level is concerned. Definitions of migration and migration intervals also vary widely across countries; the distinction between temporary and circular migration as a form of spatial mobility on the one hand, and migration as residential change on the other is rarely studied. This scientific group will endeavour to highlight that migration rarely occurs in a singular form but arises in multiple forms with varied drivers and impacts. This scientific group will highlight the limitations of current area-level secondary data, the inconsistencies in migration definitions across countries, and advocate for the use of innovative digital data and digital footprints to capture the full complexity of mobility.
  5. Mapping the relationship between people and places is crucial, yet reliable, up-to-date spatial data at lower administrative levels, such as town and ward, is often lacking, particularly in the non-metropolitan areas. This group will identify gaps in mapping and visualisation to support more informed urban planning and climate adaptation strategy.
  6. While the impacts of climate-related mobility and migration span multiple sectors —including livelihoods, food security, nutrition and health —this group will place a particular focus on the health consequences for mobile and vulnerable populations, both at the places of origin and destination.

Expectations and Outcomes (2025-2027):

This initiative aims to advance research, collaboration, and policy dialogue on the impacts of climate change on mobility, migration, and health across Asia. Through a series of strategic activities (detailed below)—including conferences, publications, collaborative research, capacity building, stakeholder engagement, and advocacy—the group will foster academic innovation, strengthen research networks, and inform evidence-based policy and practice.

i. Conference and Sessions:
