LO 9 – Crop diversification and opportunity for climate change resilience


Crop diversification means growing more than one crop in an area. Diversification can be accomplished by adding a new crop species or different variety, or by changing the cropping system currently in use. Commonly, it can mean adding more crops into an existing rotation.
Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a farm. Applying horizontal and vertical diversifying, farmers increase the range of potential food and income sources available to them.
Implementation of new diversification biotechnology introduces new cultivated species improving crop varieties that enhance plant productivity, quality, health and nutritional value. At the same time, this approach increases the crop resilience towards diseases, pest organisms and environmental stresses. Crop diversification is often promoted as a strategy to achieve climate resilience and is an effective strategy to deal with climate variability. It refers to the addition of new crops or cropping systems to agricultural production taking into account the different returns from value-added crops with complementary marketing opportunities.
