climate smart agriculture: opportunities and stumbling blocks
DESCRIPTION
This presentation by Marius van den Berg from the Institute for Environment and Sustainability explains briefly what climate-smart agriculture is what effects and interrelations farm management practices associated with CSA have, how CSA was adopted and which policies enabled it and what can be taken home from that.TRANSCRIPT

Overview• Context: What are we talking about
• Farm management practices associated with CSA
• Effects (advantages and
disadvantages)• Interrelations
• Adoption of CSA
• Enabling policies
• Take-home messages
What are we talking about?
The three pillars of climate smart agriculture:
• Sustainably increasing agricultural productivity and incomes
• Adapting and building resilience to climate change
• Reducing and/or removing greenhouse gases emissions, where possible

Agriculture
Climate smart agriculture
To sustain the three pillars:
• Increase in crop yields and animal feed use efficiency
• Minimise conversion of (semi-)natural land to arable land
• Improve/sustain soil health and biodiversity to adapt and build resilience to climate change
• Efficient use of inputs (water, fertilizers, agrichemicals)
10April 14, 2023
Examples of measures• Adapted/more productive/resilient crop varieties or animal breeds
• Adapted crop calendar
• Crop rotation / Intercropping (especially with N-fixing crops)
• Minimum soil disturbance (e.g. no till or minimum tillage)
• Crop residues left on the land
• Semi-natural vegetation intertwined with cropland
• Better irrigation practices
• Smarter use of chemicals (only when needed, at the right place and the
right time; biological pest control when possible)
• Rehabilitation of degraded land
• Improved animal husbandry
• Better integration of animal manure in crop production
• Minimise harvest and post harvest losses 11

Example 1: Conservation agriculture
12April 14, 2023
Example 1: Conservation agriculture• Crop rotation (e.g. soybean - wheat)
• Minimum soil disturbance (direct drilling, no-till)
• Crop residues left on the land after harvest
Advantages:
• High yield potential thanks to improved soil-health and water conservation
• Less need of fertilisers
• Higher C-storage in the soil
• less CO2 from field machinery use
• Less labour requirements
Stumbling blocks:
• Crop residues left on the land cannot be used for other purposes
• No-till can pose difficulty to crop emergence (esp. during transition phase)
• New pest/diseases may appear (esp. during transition phase)
• Weed infestations
• Lack of local knowledge farmers, suppliers, extension officers

Example 2: Intertwine semi-natural vegetation with cropland
vs
Example 2: Intertwine semi-natural vegetation with cropland• A coherent network of semi-natural features (hedgerows, buffer strips, flower strips,
woodlots, semi-natural grasslands etc.) in agricultural areas
Advantages:
• provides corridors for species migration,
• Pollination
• Bioogical pest control
• Erosion control
• Opportunities for supplementary income (e.g honey, agritourism)
Stumbling blocks & drawbacks:
• Loss of crop land area
• Implementation costs
• Use of heavy field machinery restricted
• New pest/diseases may appear (esp. during transition phase)

Example 3: Better irrigation practices

Example 3: Better irrigation practices• Reduce losses from reservoirs and channels
• Efficient, properly maintained equipment (e.g. drip, central pivot, short furrow)
• Improved irrigation scheduling
Advantages:
• Higher yields can be obtained with same amount of water
• Less negative off-site effects
• More efficient nutrient use
• Energy savings (from pumps)
Stumbling blocks:
• Initial investments at farm and catchment level
• Only works if water is valued
• Lack of knowledge / awareness

Common features• Fairly simple measures (more sophisticated measures also exist)
• Approaches can be applied to many environments, but local adaptation is required
• Measures tend to enhance each other (synergy)
• Drawbacks tend to be strong during initial phase
• Action required at farm and higher levels
• Costs tend to be concentrated on farmers, benefits for society as a whole
• Policies are required to overcome drawbacks
21April 14, 2023
Enabling conditions for adoption• Prices of produce and inputs are fair and fairly predictable
• Markets are reliable
• Land tenure is secure
• Credit to invest in long-term land productivity is available and accessible
• Training opportunities
• Trust that adoption will improve stakeholders’ livelihoods
• Low yield risk; or technologies/insurance mechanisms are available to cope with risks
• Incentives exist to safeguard public goods and services

Climate risk management – Need for innovative financing mechanisms
• Agricultural insurance as means to reduce risk;
• Traditional insurance schemes are not fit for climate-related risk;
• Weather index-based insurance schemes provide interesting alternative;
• Many pilots in developing countries
• Additional benefit: Farmers are exposed to intensive and better use of climate information in the decision making process;

The 3 measures are: Maintaining permanent grassland (National, or Regional, or farm)
Annual decrease of “Area grassland/total agriculture area” < 5%
Crop diversification (farm level)At least 2 crops when arable land > 10 haAt least 3 crops when arable land > 30 ha
Main crop cover < 75% of arable land, two main crops < 95% of the arable land
Ecological focus areas of at least 5% of the arable area of the holding (farms with area >15 hectares)
EFA: field margins, hedges, trees, fallow land, landscape features, biotopes, buffer strips, afforested area
This figure will rise to 7% after 2019 (after impact assessment in 2017)
NB: Organic farms, some Agri-environment schemes already compliant

Take-home messages• Implementation of climate smart agriculture is an issue of today
• Suitable approaches are available; many are based on simple technologies
• Climate smart agricultural practices tend to be synergistic. Synergism cannot be taken for granted.
• Diverse pathways of climate smart agricultural development; no one-size-fits-all solutions.
• Common stumbling blocks to adoption:
Initial investments and practical difficulties during transitional period
Costs mainly faced by farmers; benefits shared among wider community
Difficulty to achieve concerted action at several organisational levels
Minimum set of enabling conditions is often not in place
