- Early stages of crop growth versus earlier and more intense heat waves
- Early stages of crop growth versus earlier spring frosts
- Vernalization needs (cold requirements to trigger flowering)
- Water needs
- The capacity of adaptation depending on socioeconomic aspects
Systems approaches of CSA in crop production
Climate-Smart Agriculture emphasizes a holistic approach that considers the entire agricultural system:
- Landscape perspective: considers the interactions between various land-use types (e.g., farms, forests) within a specific area.
- Ecosystem services: recognizes the importance of healthy ecosystems for agricultural productivity (e.g., pollination, soil fertility).
- Value chain approach: considers all stages of production, from input supply to market access, to ensure sustainability.
Examples of CSA Practices
Conservation agriculture (CA)
Focuses on soil preservation and erosion minimization through three core practices:
- minimal soil disturbance (no-till farming),
- permanent soil cover using crop residues or cover crops,
- and crop rotation.
By improving soil structure and water retention:
- contributes to climate change mitigation by enhancing carbon sequestration and reducing greenhouse gas emissions.
- Make crops more resilient to extreme weather, thus ensuring sustainable agricultural productivity.
Regenerative Agriculture (RA)
Aims to restore and revitalize soil health, ecosystem biodiversity, and community well-being. It incorporates practices such as holistic livestock management, agroforestry, cover cropping, crop rotation and reduced tillage to increase soil organic matter, enhance ecosystem services, and sequester carbon.
Mitigates climate change by drawing down atmospheric carbon but also builds agricultural resilience to climate impacts through improved water management, soil fertility, and ecosystem health.
Organic Agriculture (OA)
Organic agriculture eschews synthetic pesticides and fertilizers, emphasizing natural inputs and methods like composting, biological pest control, and crop rotation to maintain soil health and ecosystem balance.
By relying on organic inputs and enhancing biodiversity, this method reduces pollution and greenhouse gas emissions, contributing to climate change mitigation.
It also fosters adaptation by improving soil structure, fertility, and farm biodiversity, making systems more resilient to pests and changing climate conditions.
Precision Agriculture (PA)
Leverages technology such as GPS mapping, soil sensors, and data analytics to optimize field-level management. This approach maximizes efficiency in resource use (water, fertilizers, pesticides) and increases crop yields by applying the precise amount of inputs needed at the right time and place.
Mitigates climate change by reducing input overuse and associated emissions, and it aids adaptation by enabling more accurate and responsive farming practices to local environmental conditions.
Integrated Pest Management (IPM)
Combines biological, cultural, physical, and chemical tools in a coordinated way to manage pest populations at economically acceptable levels while minimizing risks to humans, animals, and the environment.
Include crop rotation, natural predators, resistant varieties, and targeted pesticide application. This approach helps mitigate climate change by reducing the reliance on chemical inputs and enhances adaptation by promoting diverse and resilient agricultural ecosystems.
Nutrient Management
Involves the precise application of fertilizers (organic or synthetic) based on soil tests, crop needs, and environmental conditions, aiming to optimize plant nutrition while minimizing environmental impacts.
Effective nutrient management strategies:
- reduce the runoff of excess nutrients, preventing water pollution and greenhouse gas emissions.
- supports adaptation by improving crop health and resilience to stressors, ensuring sustainable food production in the face of climate variability.
Agroforestry
Agroforestry combines trees with crops or livestock within agricultural systems to mimic natural ecosystems, enhancing biodiversity, soil health, and productivity.
Offers benefits like carbon sequestration, improved water management, and soil stabilization, making significant contributions to both climate change mitigation and adaptation by storing carbon and stabilizing agricultural microclimates.
Smart Irrigation
Smart irrigation employs technology, such as sensors and automated systems, to optimize water use in agriculture, ensuring water is applied efficiently to crops.
Reduces water waste, conserves energy, and decreases greenhouse gas emissions, aiding in climate change mitigation. Additionally, by adjusting irrigation based on real-time environmental data, it enhances adaptation to climate variability, supporting sustainable water management and agricultural resilience.
Protection Tools in Agriculture
Shield crops from pests, diseases, and environmental challenges, leveraging a range of strategies from physical barriers to genetic enhancements.
They mitigate climate change by reducing the need for chemical inputs and enhance adaptation by making crops more resilient to changing weather patterns, thus securing food production with lower environmental impact.
Appropriate Selection of Crops, Varieties and managing strategies
Involves choosing crop species, varieties and managing strategies (Type of pruning or work calendar, for example) that match local conditions to optimize agricultural sustainability and resilience.
It aids in climate change mitigation by enhancing agricultural efficiency and supports adaptation by preparing farms to cope with climatic fluctuations, ensuring sustainable and resilient food systems.

What would you do? A Farmer’s dilemma
Maria is a small-scale farmer in a rural community known for its fertile land and high-quality corn production. For generations, her family has relied on traditional farming practices, including annual tilling and intensive pesticide use.
The Challenge: Recent years have brought unpredictable weather patterns, including more frequent droughts and intense heat waves. Maria has noticed a decline in her corn yields, reduced soil moisture retention, and an increase in pest problems.
The Question: If you were in Maria’s place, what would you do? How could you adapt your farming practices to ensure long-term sustainability for your land, your livelihood, and the community’s food security?
What would you do? Analyzing the problem
Individually or in groups, discuss and answer the following questions:
- What are the potential causes of the declining corn yields and increased pest problems Maria is experiencing? (Consider information from Module 7 of the FAO source and Module 3 of the CSAG Guide)
- What are the potential drawbacks of Maria continuing to use traditional farming practices under the changing climate conditions? (Consider the information from the same sources)
- List the potential benefits of Maria adopting climate-smart crop production practices. (Refer back to Module 7 of the FAO source and other learning materials)
What would you do? Developing solutions
Individually or in groups, brainstorm and propose solutions for Maria’s situation:
- Identify at least two specific climate-smart practices Maria can implement on her farm. (Consider practices like conservation agriculture, integrated pest management, or water-saving irrigation)
- For each chosen practice, explain how it can address the challenges Maria is facing (declining yields, soil issues, pests) and contribute to long-term sustainability.
- Identify potential challenges Maria might face when adopting these practices (e.g., knowledge gaps, financial constraints, access to resources).
- Suggest ways to overcome the identified challenges. (Consider potential sources of support like extension services, training programs, community collaboration, financial assistance options)
