Summary of "Adapting to Climate Change: The Case of Rice in Indonesia"

Core Content

This report, published by the World Bank in July 2008, examines the challenges and opportunities for adapting to climate change in Indonesia's rice sector. It highlights the critical role of rice in Indonesia's economy and food security, as well as the environmental and economic impacts of climate change on agricultural production. The study was conducted in response to the government's request to build on earlier work and propose longer-term solutions for rice policy.

Main Points

1. Background and Context

• Indonesia is the third-largest emitter of greenhouse gases (GHG) globally, primarily due to deforestation, peatland degradation, and forest fires.
• The agriculture sector is the largest employer in Indonesia (45% of labor) and contributes 17.5% to GDP.
• Poverty is largely a rural phenomenon, with 63% of the poor living in rural areas and 61% of them relying on agriculture for livelihood.
• The agriculture sector is the main source of methane emissions in Indonesia, contributing 59% of total national emissions, with 70% from rice cultivation.

2. Climate Change Impacts on Agriculture

• Climate change leads to temperature increases, altered precipitation patterns, and changes in the hydrological cycle, which affect agricultural productivity.
• The impacts can be biophysical, ecological, and economic.
• Key drivers of climate change effects include:
  • Temperature changes affecting plant and animal growth, pests, and water availability.
  • Precipitation changes influencing water supply, irrigation, and soil erosion.
  • Atmospheric CO2 changes affecting plant growth and water requirements.
  • Extreme weather events impacting production conditions and infrastructure.
  • Sea level rise affecting land use and coastal agriculture.
  • GHG reduction efforts influencing agricultural practices and input costs.

3. Rice and Climate Change

• Rice is a critical component of Indonesia's food security and rural economy.
• The doubling of atmospheric CO2 may have mixed effects on rice production, with potential benefits for photosynthesis but risks from temperature rise.
• El Niño events have historically caused production variability, with losses in dry years compensated by gains in subsequent years.
• Rice yields are more stable than other crops due to the impact of irrigation, which mitigates climate variability.

4. Adaptation Strategies

• Adaptation involves both technological and behavioral changes, such as using drought/flood-resistant varieties and reducing water use.
• Cross-cutting strategies include poverty reduction, improving information systems, strengthening planning, and enhancing disaster preparedness.
• Technology dissemination and farmer awareness are crucial for effective adaptation.
• The study emphasizes the need for a more market-oriented and efficient rice policy.

5. Fertilizer Subsidies and Productivity

• Excessive use of urea has led to poor nutrient balance, particularly low potassium (K) application, which affects rice productivity.
• The Long-Term Fertility Experiment (LTFE) at Sukamandi showed yield improvements from better fertilizer balance, especially with potassium.
• Fertilizer subsidies in Indonesia have been increased, but the current level of potassium chloride imports is insufficient to meet growing demand.

6. Role of Bulog in Rice Stabilization

• Bulog, a state-owned enterprise, is responsible for stabilizing rice prices and ensuring food security.
• However, it faces challenges in implementing effective procurement and stabilization policies due to lack of financial guarantees and legal instruments.
• The report recommends enhancing Bulog's role through increased autonomy, standing authority for imports, and financial support from the Ministry of Finance.

Key Information

• Climate Change and Rice Production: Climate change significantly affects rice production in Indonesia, particularly in regions with short monsoons, such as East Java and Bali.
• GHG Emissions: The agriculture sector is responsible for 59% of Indonesia's total GHG emissions, with 70% from rice cultivation.
• El Niño Impact: El Niño events have led to reduced rice production, but the effects are often offset in the following year due to improved conditions.
• Fertilizer Use: Excessive urea use and low potassium application have hindered productivity growth. Improved fertilizer balance can lead to yield increases of 11% to 35%.
• Bulog's Role: Bulog needs stronger institutional support to perform its role in rice price stabilization and food security.
• Policy Recommendations:
  • Increase investment in research and outreach to improve yield growth.
  • Reform fertilizer subsidy policies to support sustainable practices.
  • Enhance Bulog's autonomy and financial support to improve its procurement and stabilization capabilities.
  • Promote climate-smart technologies and better dissemination of climate information to farmers.

Conclusion

The report concludes that Indonesia's rice sector must adapt to climate change through improved research, better fertilizer policies, and enhanced institutional support for food security mechanisms like Bulog. The challenge lies in balancing short-term stabilization with long-term productivity gains and environmental sustainability. Effective adaptation requires a comprehensive approach that integrates scientific knowledge, policy reforms, and farmer participation.
