Flooding has been the most concrete and common effect of climate change in the Philippines. It has brought numerous deaths, destruction, and displacements in communities over the last decades and as the frequency and severity of flooding worsens with climate change, many places in the country are at risk of becoming uninhabitable in the next few years if the issue is not properly addressed. Experts have predicted that by 2050, the number of populations that will migrate due to the negative effects of climate change such as flooding will reach around 200 million to one billion. This study offers an assessment of the factors affecting migration decision- making due to flooding and its implications in urban planning. Through a case study on the three coastal barangays of Hagonoy, Bulacan, analysis of existing policies and interventions for flooding-induced migration, illustration of the link between flooding and migration, and identification of various planning implications, this study constructs the context on why and how individuals, households and a number of communities arrive at decisions to either stay or leave their places of origin due to frequent and severe flooding. This also lays the foundation of the general guidelines for flooding- induced migration for the study areas. Five main factors have been identified as the main considerations that the flood- affected population explore when making decisions as regards migrating to other places or staying in their areas of origin—(i) economic, (ii) socied, (iii) environmental, (iv) institutional, and (v) physical. Economic factors, specifically sources of livelihood and income, remain the fundamental element in migration decision-making. Majority of study's respondents indicated that they will opt to stay in their original homes despite the frequent and intense flooding because their livelihood has already been long established in their communities and it would be difficult for them to find other sources of income when they settle to new places. Unless good job opportunities are present in receiving communities, only then shall the affected residents choose to relocate or resettle. The existence of neighborhood network, presence of relatives or kin outside of the affected areas, existence of external support group, establishment of flooding response group within the community, collective effort on addressing and coping up with flooding, and community consultations are also highly important considerations for people affected by recurrent and severe flooding. These compose the social factors that affect the decision-making when it comes to migration. With enough support from various social groups such as family, relatives, friends, neighbors, and communities, the respondents expressed their preference to remain in their homes because they feel more secured and more confident that they can recover from the negative effects of flooding. The environmental factors cannot solely push the affected population to transfer to other areas, as re validated by this study. The flooding experience, frequency and intensity of flooding, disruptions in daily activities due to the aftermath of flooding, permanent departure from the place of origin due to flooding, extent of environmental destruction, and the declining quality of environmental resources when combined primarily with adverse economic and social conditions, can spell the difference between staying and fleeing to relatively safer zones. Institutional factors are highly regarded as reasons for flooding-induced migration. Respondents articulated that when there are programs, projects, and activities (PPAs) designed for mitigating the negative effects of flooding as well as for helping them cope up and recover, they will stay in their communities. On the other hand, some of the affected residents will choose to relocate if the local and national governments will provide appropriate and decent resettlement options. Finally, a fifth major consideration has been highlighted in the study—the physical factors. For the longest time, the physical factors of migration due to climate change and in this case, due to flooding, have been out of the limelight and are usually combined with institutional elements. The respondents emphasized the importance of flood-control measures and infrastructures in the flooding-induced migration decision-making process. The construction and presence of floodwalls or dikes, well-designed drainage systems, elevation of roads, flood-proofing of houses, and other similar flood-control infrastructures instill a sense of security and safety among the residents in the communities. These five factors namely economic, social, institutional, environmental, and physical have different levels of impact on the decision-making process, which is still predominantly controlled by male household heads. The male household head remains the top decision-maker in numerous sampled households in the study areas. The decisions formed are then relayed to the household members through an informal family meeting where ideas are discussed and executed afterwards. At present, the strategies and PPAs being implemented by the local government to address flooding-induced migration are generally in line with the provisions stipulated in DRRM Law of 2009 (RA 10121), Climate Change Act of 2009 (RA 9729), and the National Disaster Risk and Reduction Plan NDRRMP). Although these three national guiding documents lack specific provisions for flooding and migration, the Hagonoy Local Government Unit formulated their own policies, strategies, and PPAs to cater to the needs of their constituents who are affected by severe and recurrent flooding. Environmental factors alone will not directly result to migration, but it will exacerbate conditions in combination with all the other factors that could push people to move out of their homes. In connection with this the study found out that the communities do not see direct link between flooding and migration—they generally relate flooding basically to the failure in the implementation of local waste management in their municipality. only a few respondents have a grasp of flooding being a direct localized effect of climate change. This also shows that the awareness-raising, information, and education efforts of the local governments as regards climate change and its harmful effects are still short-handed and lacking. Several areas of improvement have been identified such as strengthening of the municipalities disaster risk reduction and management systems and processes, improve economic support system for livelihood, formulation of flooding-induced migration planning cycle, and construction of flood-control infrastructures. based on the significant findings several priority areas and key features of flooding induced migration planning have been enumerated towards the end of the study and these were described to guide the local government of Hagonoy in creating a comprehensive land use and development plan for the entire municipality with special attention to the coastal barangays.
