Livelihood Diversification: Coastal Livelihoods
Climate Adaptation Effectiveness
As an effort to adapt to the high amounts of rainfall that the Bicol region experiences every year due to typhoons, seaweed farmers in Rapu-Rapu, Albay utilized a more resilient seaweed species. The species is highly productive in a short period of time, given a limited space. Some seaweed species function as wave breakers which could aid in minimizing damages from storm surges as well as add to coastal protection .

Economic / Financial Effectiveness
Seaweed farming is an attractive industry due to its fast turnaround which could provide income to a community even after the onset of a storm . Returns are only significant if the minimum length of the culture lines are about 2,000 m . The mentioned minimum length can bring enough income to raise a family of five above the poverty line. In Central Philippines, the net profit in seaweed farming was determined by monitoring a 2,500m2 farm plot where both fixed off-bottom and raft long line methods were used . The values below suggest that the return on investment is high and would only take less than a year for the investment cost to be recovered. Aside from farming income, seaweed farms can also act as tourist destinations for knowledge enrichment if maintained properly . Fixed off bottom: PhP ~28,300 investment cost; PhP ~28,500 net profit per crop; 56% net income to gross percentage Raft long: PhP ~53,000 investment cost; PhP ~37,200 net profit per crop; 44% net income to gross percentage
Seaweed farming is easily learned and applied, and is gender-friendly .
There is a notable increase in the number of seaweed farmers from 100 to 300 from 2010-2017 . In Ilocos Sur, most of these seaweed farmers are women .
Seaweed farming minimizes environmental impacts because it involves no fertilizer and other chemical input. Prior to harvesting, seaweeds can also become habitats for aquatic organisms and can potentially lessen dynamite fishing and overfishing . However, it is important to note that studies  have shown that large-scale seaweed farming can affect the marine communities by drastically altering its natural state and changing its landscape. It is emphasized that more information should be gathered on seaweed farming as the industry progresses.
Seaweeds lessens the amount of greenhouse gases in the atmosphere by taking in carbon dioxide and releasing oxygen thus mitigating ocean temperature rise and ocean acidification .
