Marine Protected Areas in the Philippines How much spillover do we need? PORFIRIO M. ALIÑO, PhD The Marine Science Institute University of the Philippines Diliman 1101 Quezon City PHILIPPINES How can we reconcile sustainable fisheries utilization with marine reserves? In the previous discussions, we see the Philippines and its Southeast Asian countries experiencing similar declines in their fishery resources. Jackson et al.(2001) has implicated that this condition of overexploitation of the worlds fishery resources have been observed many times in the past even with traditional communities. Perhaps the intuitive logic has urged many countries to take steps to curb this downward trend through the establishment of marine protected areas (MPAs) and no-take zones (Fig. 1) (Roberts et al. 2002). In the Philippines, a pleasant turn of events has occurred where a burgeoning increase in the number of MPAs has been observed (Fig. 2) (Aliño et al. 2000). Establishing more marine reserves could seem initially interesting considering the high dependence of its fishing population. Historically varying objectives have been provided as the underlying basis for the establishment of a national integrated protected areas system (NIPAS) (Aliño and Uychiaoco 1999). Under the NIPAS act Figure 1. Global distribution of marine protected areas (MPAs). (Source: EMECS 2001) one of the important criteria was “representativeness” perhaps akin to the concept for establishing a global representative system of MPAs under the International Union for Conservation of Nature - Commission on National Priority Protected Areas (IUCN-CNPPA, Kelleher et al. 1995). On the otherhand, in the Philippines most of the MPAs have been established for the purpose of sustaining fisheries utilization in the adjacent fishing areas (e.g. more like the Marine Fishery Reserves as stipulated in Republic Act (RA) 8550, 1998; also see Pajaro et al. 1999). Arceo et al. 2001 summarizes the various criteria for establishment and the importance of determining the threats and root concerns of a potential priority MPA (Table 1). Figure 2. Over 400 MPAs have been reported in the Philippines. (Source: Aliño et al. 2001) The works of the tandem of Alcala (1988, 2001) and co-workers, Russ and Alcala (1996), have been one of the more acclaimed papers to demonstrate the effectiveness of having marine reserves in the recovery of depleted stocks (i.e. within the protected areas). In the Philippines, a recent initiative to look at an integrated framework of national priority conservation areas has been undertaken using a series Table 1.

(Source: Aliño et al. 2000) identify interconnected priority areas that can serve as marine corridors. These marine corridors are considered to be strategic areas which facilitate the continued exchange of materials and connectivity of various marine biogeographic regions (Aliño et al. 2001). Unfortunately the performance and effectiveness in many MPAs leaves much to be desired and thus have led to what many call “paper parks”. There seems to be a consistent indication that around at least only 10-15% of these MPAs have been effective despite the tenuous concern of sustaining the effectiveness in the long term (Kelleher et al. 1995; Aliño et al. 2001). What is interesting in the work of Alcala and co-workers is that these studies were one of the first to show evidence to indicate that there was some spillover of the accumulated biomass buildup in adjacent (Figs. 5 to 7). Subsequently they suggested that this spillover can redound to improved catch rates in the adjacent fished areas. More and more examples are starting to demonstrate indicative spillover effects from protection (Roberts et al. 2002). Thus in the Philippines, there is an explicit Figure 5. Biomass buildup of fish within the no-take areas. provision in the new fisheries code to encourage (Source: Russ 1991) Figure 6. Concomittant buildup of fish in the fished areas. (Source: Alcala 1988) the establishment of a marine fishery reserve in each coastal municipality. This has resulted in the upsurge of many small municipal reserves around the country. Lachica-Aliño (1998) has also suggested that in areas where commercial fishing has been banned for around 5 years recovery of some of the fishery stocks may be possible (Fig. 8). Russ and Alcala (1994) has shown that sustaining the no-take zone and the regulation of its adjacent areas is crucial or else the fish stock are vulnerable to decline rapidly (Figs. 9 and 10). Figure 7. Diversity of fish in Apo, Sumilon and Balicasag. (Source: Russ 1991) As part of the priority research projects under the Agriculture and Fisheries Modernization Act, the project entitled: Enhancing Sustainable Fisheries Utilization through Marine Fishery Reserves was funded through the Bureau of Agriculture Research (BAR) under its National Fisheries Network (Fig. 11). This project seeks to investigate the mechanisms for spillover at various scales: 1) short range (through adult movement) Figure 8. Map of Ragay Gulf, Philippines subdivided into “highly fished” and “less fished” based on ordination analysis suggest that areas where commercial fishing has been banned catch rate have increased. (Source: Lachica 1998) and 2) medium to long distance range (adult migration and larval dispersal mechanisms). The understanding of the mechanisms in adult fish movement utilizing tagging experiments are useful in the design of marine protected areas on the small Figure 9. Patterns of decline and recovery for the most important family in the Sumilon fishery, the Fusiliers (Caesionidae). (Source: Redrawn from Russ and Alcala (1994) in Roberts and Hawkins 2000) scale (i.e. determining boundaries and the habitat attributes important to optimize biomass buildup on site) (Figs 12a and b). This is crucial in designing the optimum size of the no-take areas (Figs 13a to d). Since fish stocks and recruitment processes are thought to be open systems, understanding the genetic Figure 10.

Conceptual framework diagram on the aquaculture and fisheries AFMA-MFR program. (Source: Aliño et al. on-going program) linkages of the stocks and their dispersal patterns would be crucial in the design of a network of protected areas. Thus the interaction of passive larval dispersal and active behavioral mechanisms of the adult and juvenile fish are important in determining sites where Island Ecosystem the best entrainment and replenishment sites are to be located. In addition, population genetic stock delineation could help gauge how reproductive output and realized stocks might be linked. The genetic affinity relationships help provide an indication for the linkage between the take and no-take area boundaries between adjacent MPAs.

Hypothesized possible spillover mechanisms in embayed areas in the medium range context. (Source: Aliño et al. 2001) linkages provide a framework which can help connect the efforts of a federation of MPA fisher managers towards having strategic framework for fisheries resource management. The Philippines has a federation called “PAMANA KA SA PILIPINAS” (Pambansang Alyansa ng mga Maliliit na Mangingisda na Nangangalaga ng Karagatan at Sanktuaryo sa Pilipinas or National Alliance of Small Fisherfolks and Sanctuaries in the Philippines) wherein this acronym means heritage. Heritage is quite appropriate since one of their main principles is to foster stewardship of their marine ecosystem heritage through a network of MPA and what they can do as steward caretakers to pass on to the next generations. Aside from the biophysical regime of the MFR resource management, of major concern is how to match the biophysical management requirements with the social and cultural dimensions in the management of these areas. Due to the open access nature of the commons, clarifying entitlements of ownership and tenure (stewardship) to the MPA is crucial to its sustainability (Fig. 15). This is also important because the subsequent institutional arrangements which unfold become complex in the take and no-take The TheMarine Marine Biogeographic BiogeographicAreas Areas I.

Reef connectivity in the South China Sea (Source: Juinio-Meñez et al. 2001) areas.Appropriate matching and hierarchical linkaging are often linked to the interaction between “ownership access (or quasi-tenurial arrangement of resources and management control” considerations. In addition, the equity concerns in the allocation of benefits accrued from the protection play a strategic role in sustainable financing and other noneconomically linked benefits (e.g. empowerment, emancipated self-esteem and sense of community and heritage). As implied here, a more holistic perspective of MPAs do not only refer to the no-take zones but equally as critical are these areas outside the no-take areas (Fig.16). Thus fisheries management and MPA management are often viewed in the context of integrated coastal management (ICM) (Fig. 17). As mentioned in the earlier section, mariculture and sea ranching has been also viewed as complementary to MPA management and the context of coastal zoning, co-management and ICM (Fig. 18). This situation is exemplified in the experience of the sea urchin fishery collapse and its eventual combination of grow-out and reseeding in Bolinao, Pangasinan (Juinio-Meñez et al. 2000). In the early 1990s the Figure 15. Management aptitude of Fijan customary fishing rights areas (Source: Polunin et al. 1996) Figure 16. The importance of MPAs as part of adaptive management as a “canary” to other stresses outside of overfishing. (Source: Polunin et al. 1996) sea urchin fishery in Bolinao was a multimillion peso industry which collapsed (Fig. 19). In 1997 due to completion of the hatchery production technology adoption, the closure of the life cycle of the sea urchin Tripnuestes gratilla was achieved and linked to the fishery resources management interventions. Thus reseeding and grow-out of hatchery produced sea urchin juveniles were pursued together with fisher cooperators. These mini-grow out areas (where cooperators were made to understand that they have to wait for the juveniles to spawn before they can harvest them) serve like de-facto marine reproductive reserves. In addition, the reseeding in MPA no-take areas require that the MPA also be managed like a sea ranching area, where spillover of biomass are treated as the main interest of their stewardship investments (Fig. 20). This experience may be one possible indication where spillover can be enhanced. Based on our initial simulation scenarios of spillover of MPAs and the area needed for recovery of stocks from overexploitation, it would take an unreasonably large area to achieve recovery (Hilomen et al. 2002). Figure 17. The participatory municipal coastal development plan of Bolinao, Pangasinan helps to provide integrated framework through zoning and community stewardship. (Source: Junio-Meñez et al. 2001) Figure 18. Combine sea ranching, grow-out and stewardship in fishery management (Source: Polunin et al. 1996) Aside from the local and national concerns of MPAs, transborder agreements have been initiated in some parts of the Philippines. The bilateral transborder agreement between Malaysia and the Philippines on the Turtle Islands is a good example of how marine protected areas offer value-added benefits to maintaining goodwill among neighboring states aside from sustaining fisheries and protecting endangered species. In addition, the large marine ecosystem (LME) approach referred to in our earlier discussions is not only being pursued from an esoteric academic standpoint but also efforts are under way in applying this in an ecoregional vision-mission, to manage LMEs as seen in the Sulu-Sulawesi Marine Figure 19.
