Agricultural Approach

Protected Vegetable Cultivation

In Cebu, farmers face a difficulty in increasing the supply of vegetables to meet the demand due to erratic weather conditions, heavy rainfall, and rampant disease and pest infestation. Protected cultivation technology through rain shelters provides an environment that limits the effects of drastic climatic events, disease, and pests. This is currently being applied to vegetables such as lettuce, french beans, tomatoes, and bell peppers in Mantalongon, Dalaguete, Cebu.

Climate Adaptation Effectiveness

The rain shelters provide protection from heavy rainfall, strong winds, and disease and pest infestation to minimize crop damage.

Evaluations

Economic / Financial Effectiveness
Mid

The initial upfront cost amounts to PhP 40,000/150m2 with a two-year return on investment. Rain shelters allow vegetable production year round and increase in vegetable yields, thereby increasing the income of the farmers. During times of poor weather conditions, the vegetable could be marketed at a higher price. There is an expected 58% return and an additional annual profit of PhP ~14,010.

Technical Feasibility
High

It is recommended to conduct workshops to orient farmers on the construction of the structures, installation of the irrigation system, and farm management. The construction cost for the rain shelter is much lower compared to other protective structures because it uses steel pipes for its frame and polyethylene plastic for its cover. The structure lasts about ten years while the plastic is replaced every three years at the start of the cropping period.

Social Acceptability
Low

In Montalongan, Cebu, 5% of vegetable farmers currently adopt protected cultivation to maximize year long crop production. Hesitation in adaptation of this solution is due to the upfront costs.

Environmental Impact
Mid (+)

Rain shelters provide a controlled environment for the vegetables limiting pest infestation. This lowers pesticide and chemical fertilizer use, improving water and soil quality.

Mitigation co-benefit

Limited pesticide and chemical fertilizer use reduces carbon emissions and groundwater contamination.
