20. Trends of the presence of mycotoxins in cereal grains in North Western
Europe over the period 1989-2009 for 3-acetyl-deoxynivalenol (3-Ac-DON) in oats (a),
deoxynivalenol in oats (b) and wheat (c) and of zearalenone in maize (d). The presence of mycotoxins is
indicated by the percentage of samples that contained the toxin above the level of detection.
Except for the presence of DON in wheat (c), the effect of year on the
presence of the toxin was significant.

Resilience Indicator
Model (VRIM), which

different Countries
(IPCC).
64. Global warming affects GHG emissions from
livestock systems
1. Lower quality of feedstuffs: ↑ CH4 emissions from EF.
2. Reduced efficiency in feed utilization due to heat stress:
↑ CH4 emissions from EF.
3. Reduced life expectancy: a rapid turnover of milkers
means that energy inputs and GHG outputs are ‘wasted’ in
the process of rearing heifers before they reach first
pregnancy and lactation.
4. Higher mortality rate: ↑ emissions of GHG for disposal of
carcasses.
5. Higher environmental temperatures: ↑ N2O emission from
manure.
6. Less need for warming in cold climates: ↓ on farm fossil
fuel need.
66. Adaptation (definitions)
• IPCC: Adjustment in natural or human systems in response
to actual or expected climatic stimuli or their effects,
which moderates harm or exploits beneficial opportunities.
• European Commission: Cost-effective actions taken to cope
with a changing climate and aimed at reducing the risk and
damage from current and future impacts.
67. • Structural interventions: Buildings orientation,
insulation and reflectance; shading; ventilation with
or without use of water
• Management: feeding, water sources (crops and
livestock), reproduction, disease control and
surveillance (crops and livestock), genetic selection
(crops and livestock)
• Proactive behavior: heat alert, insurance systems,
regulation

• Spreading knowledge on climate change

• Providing guidance on best approaches;
• Coordinating national activities,

Finding ways of adapting to climate change will be crucial for the
agricultural sector in the years to come. Coupling adaptation efforts
to climate-change mitigation efforts will enable farmers to work
with, and not against, the environment.
Measures include:
• Introducing crop rotation to make the most of the available water;
• Rewarding farmers who carry out sustainable practices;
• Using different crop varieties which are more resistant to heat or
drought;
• Altering sowing dates and other practices to adapt to changing
weather patterns;
• Modernizing farm buildings and machinery to make them more
energy efficient;
• Providing more information and training to keep farmers informed
on climate change impacts.

• Analysis of regional bioclimate scenarios may help
farmers, nutritionists, veterinarians, and policy-
makers to develop appropriate anticipatory adaptation
strategies to limit the consequences of climate change
for the livestock sector
• Bioclimate scenarios indicate that climate changes will
impact dramatically on animal health, welfare and
performances
• Need for regional economic analysis aimed at
establishing costs and potential benefits of
anticipatory adaptation actions in a context of
economic and bioclimate uncertainty
