Agricultural Approach: Agroforestry
Climate Adaptation Effectiveness
The presence of trees in farms reduces climate risks with the introduction of deep root systems. These deep root systems allow the farms to adapt to drought or low rainfall events by increasing soil porosity and reducing runoff which leads to increased water infiltration and retention. These systems also absorb more water and nutrients due to its far reach into the soil profile. Higher evapotranspiration rates have also been associated with these systems thus aiding in the aeration of the soil which promotes release of moisture during low rainfall periods .

Economic / Financial Effectiveness
Agroforestry reduces overall input such as fertilizer and water in the production of crops. Although there is a possibility of lowered crop yield due to the trees occupying portions of the farm area, studies show that implementing agroforestry would be much more economically beneficial in the long run. This is due to the addition of products coming from the trees which diversifies the sources of income; and the ability of agroforestry to reduce climate change risks. This maintains productivity of the land all year round, and promotes food security . However, it should be noted that the effectivity of agroforestry depends on tree species planted, soil characteristics, agricultural practices, and other factors .
Enhancing technical knowledge and capacity building for farmers are needed before agroforestry can be successfully adopted .
As of 2017, agroforestry had an adoption rate of less than 30% in Southern Luzon, Eastern Visayas, and in Southern and Eastern Mindanao .
Agroforestry promotes soil fertility and water conservation through increased water and nutrient absorption, and soil aeration by the root systems. This also increases soil organism activity which enhances subsurface biodiversity. The presence of trees also creates new habitat for wildlife .
The CRA was tested against eight climate smartness dimensions: yield or productivity, adaptation (income, water, soil, and risks), and mitigation (energy, carbon, and nitrogen). The overall climate smartness in Southern Luzon including Bicol and Eastern Visayas is 3.3, and 4.5 in Southern and Eastern Mindanao.
Agroforestry reduces greenhouse gas emissions through trees grown without the use of too much inorganic fertilizers. It also enhances soil and biomass carbon stock.
