Tajikistan: Economic and Distributional Impact of Climate Change Summary

Core Content

Tajikistan is identified as the most vulnerable country in the Europe and Central Asia (ECA) region to the adverse impacts of global climate change. This vulnerability stems from its weak social and productive structures, low adaptive capacity, and existing challenges such as land degradation, water scarcity, and frequent disasters. The country's economy is heavily reliant on agriculture, which is particularly susceptible to climate variability, and over two-thirds of its population lives in rural areas where livelihoods are more directly affected by climate change.

Key Messages

• Tajikistan is highly vulnerable to climate change due to its weak infrastructure, low productivity, and high exposure to natural disasters.
• Public awareness of climate change is high, with health risks, natural disasters, and agricultural impacts being the primary concerns.
• Climate change can exacerbate poverty by reducing agricultural yields, increasing food prices, and spreading water-borne diseases.
• Regions with greater agricultural dependence and lower socioeconomic indicators are most vulnerable, especially the eastern mountain area of the Region of Republican Subordination (RRS), the Southern Sughd hills, and the Khatlon hills and lowlands.
• Socioeconomic development is the most effective adaptation strategy, as it enhances income diversification, health, education, and access to services and infrastructure.

Public Perceptions of Climate Change

A nationally representative household survey (P-LITS) reveals that:

• 57% of respondents feel "very well informed" or "fairly well informed" about the potential effects of climate change.
• The most significant concerns are:
  • Extreme hot/cold seasons harmful to health (30%)
  • Increase in natural disasters (25%)
  • Unpredictable/extreme weather affecting agriculture (20%)

These concerns highlight the public's recognition of the health, disaster, and agricultural impacts of climate change.

Transmission Channels and Distributional Impacts

The main transmission channels through which climate change affects Tajikistan are:

1. Agriculture

• Decline in agricultural productivity (20% reduction could increase national poverty rate by 13% and poverty gap by 24%).
• Increase in relative food prices (20% increase could raise poverty rate by 16% and poverty gap by 25%).
• Reduction in agricultural wages (20% drop could raise poverty by 2% and the poverty gap by 7%).

These effects are more pronounced in rural areas, where a higher concentration of the population is near the poverty line.

2. Health

• Poor households are more affected by health risks due to:
  • Inability to afford medical services.
  • Higher exposure to water-borne diseases.
  • Weaker immune systems from malnutrition and poor living conditions.
• 46% of the poorest households cannot afford health care, compared to 27% of the richest.
• Diarrhea incidence is 1.4 times higher among the poorest households.
• Children in the poorest quintile are almost twice as likely to be severely underweight.

3. Disasters

• The poor are disproportionately affected by disasters due to:
  • Inferior housing and location in hazardous areas.
  • Limited ability to migrate or recover from shocks.
  • Nondiversified income sources and low savings.

Regional Vulnerability Index

The vulnerability to climate change varies across regions, based on three factors:

1. Exposure – High in Gorno-Badakhshan Autonomous Oblast (GBAO) and South Khatlon lowlands due to extreme temperatures and temperature fluctuations.
2. Sensitivity – High in the eastern mountain area of the RRS, Southern Sughd hills, North-East Khatlon hills, Varzob-Zarafshan, and GBAO due to reliance on agriculture, high disaster sensitivity, and food insecurity.
3. Adaptive Capacity – Highest in GBAO and Southeast Khatlon hills, West RRS lowlands, and South Khatlon area, which have above-average income and education levels.

The vulnerability index is based on the average of these three subindices. Urban areas are the least vulnerable, while the RRS oblast, especially its eastern mountainous areas, is the most vulnerable.

Adaptation Priorities: Strategies for the Future

Effective adaptation strategies for Tajikistan should align with poverty reduction and development goals. These include:

1. Building Resilience

• Invest in agriculture and rural infrastructure.
• Promote economic diversification and off-farm livelihood opportunities.
• Improve extension services to support sustainable land management and crop diversification.
• Enhance preventive health care, hygiene, and disaster preparedness.
• Increase access to clean drinking water to reduce water-borne diseases.

2. Improving Risk Management

• Strengthen disaster management through early warning systems, infrastructure improvements, and community-based initiatives.
• Expand financial services and safety nets, especially in rural areas.
• Develop flexible safety net programs for the chronic poor.
• Improve the regulatory framework of the banking sector and support microfinance institutions to help households and small businesses accumulate assets and diversify livelihoods.

Conclusion

Tajikistan's vulnerability to climate change is deeply intertwined with its socioeconomic conditions. Addressing this requires a dual focus on both resilience building and risk management, with a particular emphasis on rural areas and poor populations. Development policies that enhance income diversification, education, and access to services are crucial for improving adaptive capacity and reducing the distributional impacts of climate change.
