Climate change, agriculture and food security

Climate change is a growing threat to the agriculture sectors. The negative effects on agricultural production and livelihoods of farmers, foresters and fisher folk are already being felt in many places. They will only get worse overtime. Unless climate change is addressed, agricultural productivity will decline with serious implications for food security. Millions of low-income people will be at risk of hunger and poverty. The agriculture sectors also contribute to climate change due to their emissions of greenhouse gases. Productivity declines could have serious implications for food security. Millions of low-income people who are already highly food insecure, are likely to be affected. Smallholder producers are amongst the most vulnerable.

How Climate Change Affects Agriculture?

Agriculture sectors are major contributors to climate change Taken together, agriculture, forestry and land-use account for at least 20% of total emissions, mainly from the conversion of forests to farmland and from livestock and crop production.

Climate change impacts:

The effects of climate change on agricultural production will have negative effects on developing countries, mainly in sub-Saharan Africa and South and Southeast Asia. Responding to climate change: sustainable agricultural practices Smallholders need support to access the right technologies and to implement them.

  • No-till
  • Cultivating nitrogen efficient crop varieties
  • Integrated soil fertility management
  • Improved fodder grasses or legumes
  • Natural predation of pests and reduction of pesticides
  • Cultivating heat-tolerant crop varieties
  • Water harvesting & sprinkler irrigation Drip irrigation
  • Precision agriculture
  • Improved pasture management

By 2050 less people could be at risk of hunger if improved agricultural technologies are adopted

Use of nitrogen-efficient crop varieties: -12%

Integrated soil fertility management: -4%

Protection of crops from disease: -3%

Cultivation heat-tolerant crop varieties: -8%

Precision agriculture: -7%

Zero-tillage: -9%

Responding to climate change:

The agriculture sectors can substantially contribute to balancing the global carbon cycle.

Agriculture

Resource use efficiency + Soil regeneration = can bind large amount of atmospheric CO2 and lower emissions of N2 0 and CH4

Forestry

Reducing deforestation + Adopting sustained-yield management = can help mitigate the rise of atmospheric CO2

Reducing food loss and waste

Improves the efficiency of the food system, reduces both pressure on natural resources and the emission of greenhouse gases (GHGs).
