Agricultural Approach: Farm Diversification
Corn-Peanut Crop Rotation
Climate Adaptation Effectiveness
Peanuts have a different growth habit from corn which enables it to provide additional nutrients to the alkaline soil where corn is grown. Corn-peanut crop rotation also breaks the pest infestation cycles lessening its impact on both crops.

Economic / Financial Effectiveness
The initial cost of implementation is PhP 51,500/hectare with a 1-year return on investment. Farmers practicing corn-peanut crop rotation in Cebu have an estimated annual profit of PhP 25,250/hectare and internal rate of return of 162%. Even if the corn and peanut yield is lower, this practice is still much more profitable than monocropping. Furthermore, the break in pest infestation cycles lowers the cost of pest management thereby lowering production cost of both crops .
This practice is most effective in uphill and hilly areas where corn and peanut can thrive. In order to encourage more farmers to apply crop rotation, the LGU could subsidize fertilizer and seedlings cost. Training could also be held to ensure the success of the implementation of the practice .
An estimated 10% of corn farmers in Cebu currently adopt this practice but it is projected to increase to 50% in the upcoming years .
Legumes such as peanuts can aid in nitrogen fixing through its symbiotic nitrogen-fixing bacteria. It produces ammonia which can serve as natural fertilizer to plants and increase soil fertility. This benefit along with the disruption in pest cycles lowers external input thus conserving resources .
Corn-peanut crop rotation is a low carbon footprint practice due to decreased use of fertilizers and pesticides leading to lower greenhouse gas emissions. Similar to other crop rotation practices, it aids in the increase of soil carbon sequestration and increasing biomass production per unit area by reducing the frequency of bare land fallow .
