G20 : Economic Cooperation ahead

Sustainable agriculture, climate change and nutrition: a complex challenge


From UPSC perspective, the following things are important :

Prelims level: G20 Initiatives

Mains level: the complex nexus of food security, climate variability, and sustainable agriculture for a resilient and sustainable future.

What’s the news?

  • The interconnected challenges of food security, climate change, and sustainable agriculture emphasize the need for a comprehensive approach. The G20 Indian Presidency can play a pivotal role in fostering international cooperation to address these issues.

Central idea

  • The intricate link between food security, climate variability, and sustainable agriculture has far-reaching consequences for the Earth and its inhabitants. Climate change threatens food security through erratic weather and extreme events, while agricultural practices exacerbate climate change, creating a damaging feedback loop.

Climate Variability and Food Insecurity

  • Climate variability, characterized by erratic weather patterns such as droughts and floods, directly impacts agriculture. It can lead to crop failures, reduced agricultural productivity, and increased food insecurity.
  • Erratic weather patterns disrupt traditional farming practices and make it challenging to predict and plan for successful harvests.
  • Vulnerable populations are disproportionately affected by extreme weather events like droughts and floods.

How does land use play a significant role in both climate change and food security? 

  • Unsustainable land use practices, such as deforestation and the expansion of agriculture, release carbon into the atmosphere, contributing to global warming.
  • On the other hand, practices like reforestation, agroforestry, and land conservation can sequester carbon and improve soil health, benefiting both agriculture and climate change mitigation.

The Role of Sustainable Agriculture

  • Mitigating Environmental Impact: Sustainable agriculture focuses on practices that aim to minimize the environmental degradation associated with conventional farming. This includes reducing the use of synthetic pesticides and fertilizers, which can harm ecosystems and water quality.
  • Maintaining or Improving Productivity: Sustainable agricultural practices are designed to maintain or even improve agricultural productivity while reducing environmental harm. This is essential to ensuring a stable and sufficient food supply, particularly in the face of climate change-related disruptions.
  • Enhancing Climate Resilience: Sustainable agricultural practices, such as crop rotation, organic farming, and reduced pesticide use, can enhance the resilience of farming systems. These practices make agriculture less susceptible to disruptions caused by climate variability, such as extreme weather events.
  • Carbon Sequestration: The article suggests that sustainable land use practices, such as reforestation, agroforestry, and land conservation, can sequester carbon from the atmosphere. This not only helps mitigate climate change but also improves soil health, benefiting both agriculture and the environment.

How can agriculture be made more sustainable and resilient in communities in developing countries?

  • Increasing Crop Diversity: Encouraging farmers to diversify their crop choices can improve resilience. Growing a variety of crops can increase the risk of crop failure due to unpredictable weather patterns and pests. Crop diversity also enhances nutrient cycling in the soil, improving overall soil health.
  • Diversifying Farming Systems: Promoting mixed farming systems that include livestock and aquaculture alongside traditional crops can enhance resilience. These integrated systems can optimize resource use, provide multiple sources of income, and improve nutrient cycling.
  • Efficient Irrigation Systems: Investing in efficient irrigation systems can help farmers cope with changing rainfall patterns and water scarcity. These systems can improve soil health and water conservation, reducing vulnerability to climate-related challenges.
  • Promoting Organic Farming Practices: Encouraging organic farming practices, which minimize the use of synthetic pesticides and fertilizers, can reduce environmental harm and improve the resilience of agricultural systems. Organic practices often focus on building healthy soils, which can better withstand climate variability.
  • Cultivating Climate-Resistant Crops: Promoting the cultivation of climate-resistant crop varieties and drought-resistant seeds, such as millets, can help farmers adapt to changing climate conditions. These crops are often better suited to withstand droughts and extreme temperatures.
  • Strengthening Market Links: Facilitating connections between farmers and markets can help ensure that farmers receive fair prices for their produce. This can improve the economic resilience of farming communities and incentivize sustainable practices.
  • Microfinance Opportunities: Providing access to microfinance opportunities can assist farmers in investing in sustainable agricultural practices. Financial support can help farmers acquire the resources they need to adopt more resilient and sustainable farming methods.
  • Policy Support: Implementing policies that emphasize sustainable agriculture and provide incentives for sustainable practices can create an enabling environment for farmers. These policies can include subsidies for sustainable practices, access to credit, and support for climate adaptation.

Global Prospects through the G20 Indian Presidency

  • International Cooperation: The G20 Indian Presidency offers a platform for international cooperation. G20 countries can collaborate and coordinate efforts to address pressing global challenges, including climate change and food security.
  • Knowledge Sharing: The G20 provides a forum for knowledge sharing among member nations. Countries can exchange best practices, share research findings, and pool resources to tackle common issues more effectively.
  • Policy Advocacy: G20 member countries can use their collective influence to advocate for policies that promote sustainability, resilience, and equity in global food systems. This can include advocating for climate-resilient agricultural practices and sustainable land use.
  • Resource Mobilization: The G20 can facilitate resource mobilization to support initiatives aimed at creating a more sustainable and resilient global food system. This includes financial support for sustainable agriculture projects and climate adaptation efforts.
  • Innovation and Research: G20 countries can promote international cooperation in agriculture research and innovation. By working together, they can accelerate the development of sustainable crop varieties, pest-resistant crops, and advanced farming technologies.
  • Global Food Security: The G20 can play a pivotal role in enhancing global food security. This involves coordinating efforts to improve food distribution systems, reduce food losses and waste, and promote sustainable agriculture to ensure a stable food supply for vulnerable populations worldwide.
  • Agricultural and Rural Development: G20 member nations can leverage their resources and expertise to support agricultural and rural development in developing countries. Investments in infrastructure, capacity development, and financial assistance to smallholder farmers can alleviate poverty and promote sustainable farming practices.


  • Fostering international cooperation is essential to addressing the complex nexus of food security, climate variability, and sustainable agriculture for a resilient and sustainable future. The G20, with its potential to drive global strategies, should play a pivotal role in coordinating efforts to mitigate climate change, adapt agricultural practices, and ensure food security on a global scale.
