How does climate change affect agribusiness?

Climate change impacts agriculture through increased frequencies of extreme climatic events such as droughts and floods that directly affect agricultural productivity and production (Jain, 2007; Thurlow et al. 2012). The impacts of climate change on crop yields differ by regions.

How does temperature change affect farming and crops?

Changes in ozone, greenhouse gases and climate change affect agricultural producers greatly because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause habitat ranges and crop planting dates to shift and droughts and floods due to climate change may hinder farming practices.

How can the effects of climate change be reduced by agriculture?

Top 5 Technologies That Help Farmers Respond to Climate Change

  1. No-Till Farming. Avoiding tillage keeps moisture, organic matter and nutrients in the soil, making farm fields more fertile.
  2. Heat-Tolerant Traits.
  3. Drought-Tolerant Maize.
  4. Crop Protection.
  5. Nitrogen-Use Efficiency.

How is agriculture adapted to climate change?

Farmers can help nature to adapt to climate change by providing good-quality habitat in which wildlife can live and move. Building up thriving populations of farmland wildlife will make our farmlands better able to cope with climate change and help secure the future of our much-loved species.
