The complexity of small islands stems from the fact that these areas are inhabited by human communities relying on its resources. Understanding small islands therefore, includes the geographic characteristics, small island biodiversity, isolation and integration concepts and the relevant contributions of the human communities residing in these spatial units. Spatial planning and management of small islands is anchored to these facts justifying the consequent need for its sustainable development. Literatures on small island development point similar unique characteristics describing the Philippine small island provinces. However, spatial strategies for small island development have still been a challenge making it as the goal of this research. Such research goal corresponds to two-pronged ideas: (1) the comprehensive profile gap analysis of the small islands, in terms of its biophysical/ ecological attributes, socio- economic characteristics and the link between the ecosystems and the local economy; and (2) the spatial interaction analysis through the natural resources of the small islands flowing along the regional spatial system. Philippine islands are fragile, vulnerable yet it supports the regional economy showing the unique characteristics and owing some bases for planning to achieve sustained development. Among 16 island provinces in the Philippines, three were chosen given its similarities in terms of geographic and biophysical attributes (physical size, biodiversity, topography, etc), population size, and socio-economic characteristics. The three small island provinces are Batanes, Siquijor and Camiguin, which represents the three major island groups in the Philippines (Luzon, Visayas, Mindanao), respectively. Including in the analysis is the descriptive roles the selected small islands perform in their regional administrative landscape namely, the Cagayan Valley, Central Visayas and Northern Mindanao regions. Current development planning activity for small islands ideally looks into the small island character that will inform better planning. However, the actual procedural methodology limitedly highlights the unique island characteristics making spatial planning not concretely targeting the actual needs of small islands. Also, the context of small island resources flow, as an expression of spatial interaction integral to provide a vivid picture of the small islands has not been given proper attention. These gaps in analysis and planning for small island provinces have been addressed through this research. Through the innovative methods applied the results show the unique character of the small island provinces stems from the socio-demographic and cultural (High Population density and low growth rate, Isola Effect, Sea-faring culture, migration patterns); environmental (coastline to physical size ratio, vulnerability to hydro-meteorological hazards and disasters, complex geographies and ecosystems, ecosystem continuum); economic (narrow and concentrated economic base, vulnerability to environmental shocks, import orientation, prominence of varied informal economy, subsistence and extractive economy); Infrastructure (Physical isolation and accessibility concerns, centralization for provision of support services); and institutions (satellite town effect, unclear hierarchical spatial roles), which were highlighted to provide bases for developing spatial strategies. Further application of the spatial interaction analyses confirmed these characteristics and provide deeper context on the actual conditions of small island provinces not seen on the xiii usual island analysis conducted for planning small islands. These results include: 1) Physical distance as an intervening factor in addressing the issues of island isolation and accessibility done through a distance analysis; 2) spatial interaction scores for small islands, through Gravity model, further solidify the existing weak human settlements interaction as a function of material resources exchange/flows, transportation and accessibity; 3) No matter how weak the spatial interaction, it does exist, however, the quality seems undervalued by disproportionate sharing of the monetary values translated from the interaction; 4) The network analysis shows a direct dependence of the identified top economic industries to the existing ecosystems in the small island, making it vulnerable to shocks on the ecosystems; 5) Material flows confirm the existence of material resources outflows; and 6) the value chain analysis done for the material
