UNFPA-R-02Resilience & PartnershipsWorkingAudience: Both2,586 words

EXECUTIVE SUMMARY

Climate change is reshaping the conditions under which sexual and reproductive health (SRH) services are delivered across Asia, increasing both demand and disruption simultaneously. This document reviews the evidence on how climate stressors — extreme weather events, slow-onset change, and displacement — affect maternal health outcomes, contraceptive supply chains, gender-based violence (GBV) rates, and access to SRH services, with particular attention to South and Southeast Asia, the Pacific, and South Asia. It maps UNFPA's current programmatic response and assesses where the evidence base is strong, contested, or absent.

The core finding is that the climate–SRHR nexus is real and documented, but programme responses remain fragmented and under-resourced. The evidence is clearest for three pathways: (1) climate disasters disrupt SRH supply chains and service access; (2) displacement and crisis conditions dramatically increase GBV and reduce contraceptive access; (3) heat stress has direct physiological effects on pregnancy outcomes. Less well-evidenced are the longer-term, slow-onset pathways — how sustained climate stress (rising seas, eroding agricultural livelihoods, water scarcity) affects SRH behaviour and outcomes over years and decades.

Asia is the region with the world's largest absolute populations at climate risk, but also significant heterogeneity: from highly exposed Pacific Small Island Developing States (SIDS) with minimal adaptive capacity, to middle-income Southeast Asian countries with stronger systems but increasing exposure, to densely populated South Asian river delta systems where flood risk interacts with pre-existing SRHR deprivation.

KEY FACTS

THE CLIMATE–SRHR NEXUS: CAUSAL PATHWAYS

Pathway 1: Acute Disaster Disruption of SRH Services

What happens: Floods, typhoons, earthquakes, and wildfires destroy or displace health facilities, disrupt supply chains, and force health workers to evacuate. Women lose access to antenatal care, skilled birth attendance, contraceptives, and GBV services precisely when demand increases.

Evidence quality: Strong. Post-disaster SRHR assessments are among the best-documented aspects of the climate–SRHR relationship. Key studies:

What works in response: The Minimum Initial Service Package for Reproductive Health in Emergencies (MISP) — documented in UNFPA-W-04 — is specifically designed for this acute phase. Evidence on MISP is reviewed in that document; the core finding is that MISP implementation improves outcomes where it is deployed, but deployment remains patchy.

Pathway 2: Displacement and SRH

What happens: Climate-related displacement — both temporary (disaster evacuation) and longer-term (abandonment of flood-prone land, coastal erosion, water scarcity) — places women in settings with higher GBV risk and reduced SRH access.

Evidence quality: Moderate-strong on acute displacement; weak-moderate on slow-onset climate migration.

Displacement and GBV:

Displacement and contraceptive access:

Slow-onset climate migration: Much less documented. Research on climate migration from Pacific islands (New Zealand's Pacific community studies) and from coastal Bangladesh suggests that migrating women face significant SRH vulnerabilities in urban or cross-border destinations. This is an important evidence gap.

Pathway 3: Heat Stress and Reproductive Health Outcomes

What happens: Extreme heat has direct physiological effects on pregnancy, increasing risk of preterm birth, stillbirth, placental abruption, and gestational hypertension.

Evidence quality: Moderate. Peer-reviewed epidemiological literature (Beltran, Strand, Ha et al.) documents associations in multiple settings. Causal mechanisms (hyperthermia, hormonal disruption, cardiovascular stress) are plausible but imperfectly understood. Most studies are from high-income settings (California, Europe, Australia); Asian-specific studies are emerging.

Asia-specific context: South and Southeast Asia are projected to see some of the world's most severe heat increases under all IPCC scenarios. Urban heat island effects in cities like Bangkok, Jakarta, Dhaka, and Manila compound baseline warming. Labour force women (garment workers, agricultural workers) face higher exposure than women in office environments — this intersects with class and occupational vulnerability.

What interventions exist: Very limited evidence on specific interventions to reduce heat-related perinatal harm in low-income Asian settings. Cooling centre access, adjusted work scheduling, heat early warning systems, and community health worker awareness programmes have been proposed but not systematically evaluated in the SRHR context.

Pathway 4: Agricultural/Livelihood Disruption and SRHR

What happens: Climate impacts on agriculture (flooding, drought, salinisation of coastal farmland) reduce household incomes, particularly for rural women. Economic stress is associated with: reduced healthcare-seeking (including SRH services), increased transactional sex, early marriage, and reduced male livelihood — which correlates with increased intimate partner violence.

Evidence quality: Weak-moderate. Theoretical links are well-established (poverty–SRHR nexus is extensively documented), but the specific climate→livelihood→SRHR pathway is hard to isolate from other poverty drivers in observational studies.

Asia-specific: This pathway is particularly relevant in:

Pathway 5: Water Scarcity and Reproductive Health

What happens: Water scarcity — worsening due to glacial retreat (Himalayas, Hindu Kush), changed monsoon patterns, and over-extraction — affects menstrual hygiene management, safe delivery practices, and healthcare hygiene standards. In extreme cases, displacement for water access creates vulnerability.

Evidence quality: Weak to moderate, particularly the direct water–SRHR pathway rather than the well-documented water–health pathway generally.

ASIA-SPECIFIC VULNERABILITIES

South/Southeast Asia

Bangladesh: Among the world's most climate-exposed countries. Delta geography means flooding is chronic, not just episodic. UNFPA has a significant country programme; existing research documents contraceptive supply chain disruption in floods and increased GBV in post-disaster shelters. The climate–SRHR nexus is explicitly incorporated into Bangladesh's national SRHR strategy, though implementation funding is limited.

Philippines: Highest typhoon frequency globally. Post-Haiyan response is the most extensively documented humanitarian SRHR operation in Asia. UNFPA's Philippines country office has become a regional centre of expertise on disaster SRHR response. The challenge is institutionalising this expertise into preparedness systems rather than reactive response.

Myanmar: Complex emergency compounding climate risk. Military coup (2021) has created governance collapse, severely restricting UNFPA access and programme delivery. Climate displacement overlaps with conflict displacement; women in both contexts are severely underserved. Accurate data is extremely difficult to obtain.

Indonesia, Vietnam, Thailand: Middle-income countries with stronger health systems but significant exposure to climate risk in rural and peri-urban areas. Climate–SRHR gaps exist particularly for indigenous and minority populations in climate-exposed regions.

Pacific Small Island Developing States (SIDS)

Pacific SIDS face existential climate threats (Tuvalu, Kiribati), not just episodic disruption. SRH service delivery systems are already extremely fragile — small populations, remote island chains, limited health workforces, high commodity costs from ocean freight. Climate impacts are accelerating:

UNFPA operates in most Pacific SIDS but with very small country programme allocations. Evidence on climate–SRHR outcomes in the Pacific is limited partly because research capacity is extremely limited in these countries.

Critical evidence gap: Comprehensive population-level data on maternal mortality, contraceptive prevalence, and GBV in Pacific SIDS is absent or outdated for most countries. This makes evidence-based programme design difficult.

South Asia (excluding Bangladesh — above)

India: Continental scale; heterogeneous climate exposure. Bihar, Assam, Odisha (flood-prone); Rajasthan (drought/heat); Kerala (erratic monsoon, landslides). Evidence on climate–SRHR nexus is emerging but thin in Indian academic literature. India's large, largely government-run SRHR infrastructure creates a different PPP landscape than other countries.

Nepal: Glacial lake outburst floods (GLOFs) are a significant and increasing risk; primary healthcare infrastructure is fragile in mountain regions where GLOFs strike. Nepal has a strong community health worker (FCHV — Female Community Health Volunteer) network that may be a resilience asset.

Sri Lanka: 2022 economic and debt crisis has interacted with climate pressure; health system has been severely strained. SRH data from this period is sparse.

Evidence Quality on Programme Effectiveness

Evidence on the effectiveness of UNFPA's climate-SRHR integration programmes is weak:

The strongest available evidence remains the MISP implementation studies (see UNFPA-W-04), which document what the acute-phase reproductive health in emergencies response achieves. Evidence on longer-term resilience-building through UNFPA programming is genuinely sparse.

CONTESTED AND UNCERTAIN AREAS

Is Climate Change Driving Increased Maternal Mortality?

The narrative of "climate change is increasing maternal mortality" is intuitive and widely asserted, but the epidemiological evidence for this specific claim is surprisingly limited. Maternal mortality rates have generally declined across Asia even in climate-exposed countries. Attribution of mortality changes to climate change (vs. other drivers — healthcare access improvement, education, contraceptive prevalence) is methodologically extremely difficult. This does not mean climate is not harmful; it means the harm is likely partially offset by other improvements, and isolating the climate signal is hard.

Honest statement: Climate change threatens to slow or reverse maternal mortality improvements, and to widen inequalities (between climate-exposed/unexposed communities). The specific size of this effect is not well-established.

GBV Data Quality in Climate Settings

GBV statistics cited in climate-SRHR literature are frequently extrapolated from general humanitarian settings rather than specifically measured in climate disaster contexts. The "GBV rates increase during disasters" finding is robust, but precise quantification is difficult because reporting environments (already low) deteriorate further in disasters.

Slow-Onset vs. Acute Climate Effects

Most programme and evidence attention focuses on acute climate events (typhoons, floods). The slow-onset effects (salinisation, temperature rise, ecosystem degradation) are less visible but potentially more transformative at population scale. Evidence on slow-onset climate–SRHR pathways in Asia is genuinely thin and represents an important research gap.

IMPLICATIONS FOR THE LKYSPP TEAM

The challenge asks about PPPs for community resilience to "climate and humanitarian stressors." This document suggests:

  1. The acute disaster response context is the strongest evidence base: MISP, supply prepositioning, and skilled birth attendant networks have documented effectiveness. PPPs that strengthen these systems (logistics companies, pharmaceutical distributors, community health worker platforms) have the best evidence.

  2. The slow-onset climate–SRHR nexus is where investment is most needed but evidence is weakest: This is a genuine frontier. PPPs targeting slow-onset impacts (agricultural livelihood support + SRHR integration; climate-adaptive community health infrastructure) are important but pioneering — the team should represent them as such.

  3. Pacific SIDS are the most acute case and the hardest to finance through PPP mechanisms: Commercial returns are essentially impossible in these geographies; any finance for Pacific SRHR resilience requires grant capital or highly concessional instruments.

  4. Community co-design is especially important in Asia given diversity: "Asia" encompasses settings from Singapore to Tuvalu; any PPP framework must be explicitly adapted to context rather than imposing a single model.

  5. UNFPA's credibility in this space rests on its humanitarian mandate and procurement capacity: A PPP framework that positions UNFPA as a technical coordinator and procurement guarantor — drawing on Singapore finance for systems strengthening — is more credible than one that positions UNFPA as a financial innovator.

SOURCES AND EVIDENCE NOTES

Key sources:

Evidence quality rating: Moderate overall; strong for acute disaster–SRHR disruption; weak-moderate for slow-onset pathways; very limited on programme effectiveness of climate-integrated SRHR investments.
