Summary of "Reducing the Vulnerability of Georgia's Agricultural Systems to Climate Change"

Core Content

This document presents a World Bank study on the vulnerability of Georgia's agricultural systems to climate change and proposes adaptation options to enhance resilience. The report is part of a broader initiative to integrate climate change adaptation into agricultural policies, programs, and investments across the Europe and Central Asia (ECA) region.

Main Objectives

• Assess the impact of climate change on Georgia's agricultural sector.
• Identify and prioritize adaptation options to reduce vulnerability.
• Provide evidence-based recommendations for policy, investment, and capacity-building efforts.

Key Climate Change Challenges for Georgia's Agricultural Sector

• Temperature Increase: All four agricultural regions in Georgia are expected to experience rising temperatures, with the most significant increases in the Eastern Lowlands region, potentially reaching up to $5^{\circ}\mathrm{C}$ by the 2040s. The national average temperature increase is projected to be about $2.3^{\circ}\mathrm{C}$ over the next 50 years.
• Precipitation Variability: Precipitation patterns will become more erratic, with greater uncertainty compared to temperature changes. Under the Medium Impact scenario, average annual precipitation may increase slightly, but under the High Impact scenario, a 24% decline is forecasted, especially in the May to October period, making late summer the driest time of year.
• Seasonal Impacts: Climate impacts will be most severe from July to September, a critical period for agricultural production.

Agricultural Sector Overview

Georgia's agricultural sector is vital to the country's economy and the livelihoods of a significant portion of its rural population. The sector is characterized by:

• Diverse agricultural regions, including Eastern Lowlands, Eastern Mountainous, Western Lowlands, and Western Mountainous.
• A reliance on irrigation, with significant areas under irrigation.
• A mix of crops and livestock systems, with a focus on staple crops and vineyards.

Impact Assessment

The study evaluates the potential impacts of climate change on:

• Crops: Projected yield changes under different climate scenarios (Low, Medium, High) indicate a range of outcomes, from modest increases to declines.
• Livestock: Climate change may affect grazing conditions, feed availability, and health of livestock.
• Water Resources: Increased water demand and reduced availability, particularly in the 2040s, pose significant challenges for irrigation and overall agricultural productivity.

Adaptation Options and Recommendations

A menu of adaptation options was developed, with the following key measures recommended:

• Irrigation Infrastructure: New and rehabilitated irrigation systems are suggested to address water shortages and improve efficiency.
• Optimized Water Use: Efficient water application techniques are highlighted to reduce waste and enhance productivity.
• Improved Drainage: Particularly in the Western Lowlands, improved drainage systems can mitigate the risks of waterlogging and enhance crop resilience.
• Crop Variety Optimization: Selecting and cultivating climate-resilient crop varieties is emphasized to improve yields and reduce vulnerability.
• Optimized Fertilizer Use: Better fertilizer management can increase productivity and reduce environmental impact.
• Water Storage Solutions: Basin-wide water storage is proposed to manage seasonal variability and ensure water availability during dry periods.

Methodology and Limitations

• Approach: The study combined quantitative economic modeling, qualitative analysis by experts, and participatory workshops with farmers and stakeholders.
• Limitations: The analysis is based on projected climate scenarios and may not account for all variables, including socio-economic changes and technological advancements.

Stakeholder Engagement

• The report reflects the outcomes of stakeholder consultations and workshops in various regions of Georgia.
• Recommendations were prioritized based on input from local farmers, agronomists, and experts, ensuring that the measures are context-specific and relevant to the needs of the agricultural communities.

Conclusion

The report underscores the urgency of developing a climate-smart approach to agricultural development in Georgia. It provides a comprehensive set of adaptation options and recommendations, emphasizing the need for policy alignment, institutional capacity building, and targeted investments in infrastructure and practices to enhance resilience and ensure sustainable agricultural production in the face of climate change.
