Climate-Smart Agriculture — UPSC Environment Notes

Climate-Smart Agriculture (CSA) pursues three simultaneous goals: raising productivity, building climate resilience, and reducing GHG emissions. Coined by the FAO in 2010, CSA is now a pillar of UNFCCC’s agricultural agenda under the Sharm el-Sheikh Joint Work on Agriculture (COP27). For India — where 58% of the population depends on agriculture, and rainfed farming covers over 60% of cultivated area — CSA is not optional. For UPSC, this intersects GS-III (agriculture, environment, climate change) and GS-II (food security).

What is Climate-Smart Agriculture?

Definition (FAO)

CSA is an integrated approach to managing landscapes — cropland, livestock, forests, fisheries — that addresses the interlinked challenges of food security and climate change.

The "triple win"

CSA pursues three objectives simultaneously:

1. Sustainably increase productivity and incomes.
2. Adapt and build resilience to climate change.
3. Reduce/remove GHG emissions where possible.

CSA doesn't require every practice to produce all three wins — rather, it minimises trade-offs and seeks synergies across short and long time horizons.

Why agriculture needs a climate-smart approach

Agriculture's vulnerability

• Higher temperatures reduce yields — especially wheat, rice.
• Monsoon variability increasing; dry spells and flood spells alternating.
• Pest and disease distributions shifting poleward.
• Water stress rising.
• Heat stress on livestock.
• Sea level rise causing saline intrusion into coastal farms.

Agriculture's contribution to climate change

• Agriculture, forestry, land use: ~22% of global GHG emissions.
• Methane from rice paddies and livestock.
• Nitrous oxide from fertilisers.
• CO2 from deforestation for agriculture, soil carbon loss.
• India's share: ~14% of national GHG emissions from agriculture.

Elements of CSA

CSA is not a fixed set of practices but a locally adapted approach. Key elements:

1. Farm management

• Crop, livestock, aquaculture management balancing food security with adaptation and mitigation.
• Diversification of cropping patterns.
• Improved varieties — drought/flood/heat-tolerant.

2. Ecosystem and landscape management

• Conservation of ecosystem services — watersheds, soil carbon, pollinators.
• Agroforestry — integrating trees with crops.
• Integrated pest and nutrient management.

3. Services for farmers

• Climate information services — weather forecasts, advisory.
• Weather-indexed insurance — Pradhan Mantri Fasal Bima Yojana.
• Early warning for extremes.

4. Wider food systems

• Demand-side measures — dietary shifts, food loss reduction.
• Value chain efficiency.
• Sustainable procurement.

CSA practices

On-farm

• Conservation tillage — zero/minimum tillage.
• Crop diversification and rotation.
• Mulching.
• Precision irrigation — drip, sprinkler.
• Climate-resilient varieties — drought-tolerant pulses, submergence-tolerant rice (Swarna Sub1).
• Integrated Farming Systems (IFS) — crops + livestock + fish + trees.
• Natural farming — zero chemical inputs.

Beyond farm

• Carbon farming — soil carbon sequestration practices.
• Agroforestry.
• Watershed management.
• Wind and solar pumping (KUSUM).

India's policy and programmes

National Mission on Sustainable Agriculture (NMSA)

One of the 8 missions under NAPCC. Key sub-missions:

• Rainfed Area Development (RAD).
• On-Farm Water Management (OFWM) — PMKSY.
• Soil Health Management (SHM).
• Climate Change Adaptation — NICRA at ICAR.

National Innovations on Climate Resilient Agriculture (NICRA)

• Launched 2011 by ICAR.
• 151 Climate Resilient Villages across vulnerable districts.
• Develops and demonstrates drought/flood/heat-tolerant technologies.

PKVY — Paramparagat Krishi Vikas Yojana

• Promotes organic farming.
• Clusters of 50 acres.

PM-PRANAM (2023)

• Promotion of Alternate Nutrients for Agriculture Management.
• Incentivises states to reduce chemical fertiliser use.

Natural Farming Mission

• National Mission on Natural Farming — launched 2024.
• Target: 1 crore farmers in 15,000 clusters.
• Promotes desi cow-based farming (Bharatiya Prakritik Krishi Paddhati).
• Andhra Pradesh’s ZBNF (Zero Budget Natural Farming) is a flagship model.

Other schemes

• Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) — "Har Khet Ko Pani".
• Pradhan Mantri Fasal Bima Yojana (PMFBY) — crop insurance.
• KUSUM — solar pumps and agri-solar.
• Soil Health Cards — over 22 crore issued.
• eNAM — digital market linkages.
• Agri-Infrastructure Fund — post-harvest.

International platforms

• Adaptation of African Agriculture (AAA) — India supports.
• FAO-led CSA initiative.
• 4 per 1000 Initiative — soil carbon sequestration.

Implementation actions for CSA

Evidence base

• Climate impact assessment in agricultural sector.
• Identifying vulnerabilities, adaptation options, mitigation potential.
• Cost and barrier analysis.

Enabling policy

• Policies and plans aligned with agriculture, climate, food security.
• Coordination across ministries.

Strong local institutions

• Empower farmers through FPOs (Farmer Producer Organisations).
• Build capacity of policy-makers.

Finance

• Climate finance — GCF projects on adaptation.
• Private investments in CSA startups.
• Green bonds for agri-climate projects.

Gender in CSA

• Women are 60-80% of India's farm labour but own <14% of land.
• CSA must mainstream:
• Gender-sensitive extension.
• Training women in climate-resilient practices.
• Credit access for women farmers.
• Women-led FPOs.

Challenges

• Small and marginal farmers (86% of holdings) face transition costs.
• Extension gap — agri-universities and KVKs under-resourced.
• Market incentives — CSA produce often not differentiated.
• Subsidy distortions — fertiliser subsidies discourage natural inputs.
• Data gaps — monitoring soil carbon, water use, emissions.
• Climate-resilient seeds — limited variety availability.

Latest developments (2024-26)

Updated context: verify with MoA&FW and ICAR annual reports.

• National Mission on Natural Farming (2024) — full operationalisation.
• Budget 2024-25 — pulses and oilseeds mission; climate-resilient crop promotion.
• COP28 Dubai — Agriculture Initiative for Climate Change; endorsed by 150+ countries.
• Sharm el-Sheikh Joint Work on Agriculture — COP27 decision operationalising CSA.
• Koronivia Joint Work on Agriculture — predecessor, now absorbed into Sharm el-Sheikh track.
• India's Green Credit Programme (2023) — includes sustainable agriculture.
• PM-KISAN digital ID integration.

UPSC relevance

GS-III mapping

• Agriculture, environment, climate change.
• Food security.

Prelims bullets

• NMSA — one of 8 Missions under NAPCC.
• NICRA — since 2011, ICAR.
• PKVY — organic farming scheme.
• PM-PRANAM — reducing chemical fertiliser use.
• 4 per 1000 Initiative — soil carbon.
• ZBNF — Zero Budget Natural Farming (AP model).
• KUSUM — solar pumps.

Mains angles

• "Climate-Smart Agriculture offers triple wins but implementation in India is constrained by smallholder realities. Critically examine."
• "Discuss the role of the National Mission on Natural Farming in India's climate-resilient agriculture strategy."
• "Evaluate India's policy ecosystem for climate adaptation in agriculture."

Essay hooks

• Farming the future — climate resilience as food security.
• Gender and climate — women farmers as CSA agents.
• Soil carbon as climate solution.

Quick revision

Bottom line for UPSC: Climate-Smart Agriculture is not a silver bullet but a framework for aligning India's farming future with climate and food-security imperatives. The NMSA, NICRA, PM-PRANAM, and Natural Farming Mission provide the policy scaffolding; translating it into smallholder action is the unfinished work.
