    Vulnerability drivers for small pelagics and milkfish aquaculture value chain determined through online participatory approach
    Macusi, Edison D.; Geronimo, Rollan C.; Santos, Mudjekeewis D. (Elsevier, 2021-11)
    Climate change impacts on the fisheries can be short-term or long-term, making them highly vulnerable. Fishers' vulnerability encompasses several factors and includes, among others, their sensitivity, exposure to the elements, and their adaptive capacity. The main aim of this study was to help develop a vulnerability assessment tool that can be applied in the various nodes of the fisheries and aquaculture value chains with a long-term view of enhancing the resilience of the fisheries and helping increase the adaptive capacity of the fishing communities. A participatory technique using online workshops was conducted together with various stakeholders (N = 214) who gave insights and suggested indicators that drive climate change impacts and vulnerability. Based on the online workshops conducted, the common hazards/drivers were increasing temperature, typhoons, flooding (sea-level rise), and the recent pandemic, which consequently destroy coral reef ecosystems, affect fisheries yield, increases fish mortality, damage boats, fishing gears, pens, cages, pond dikes, erode beach properties, and devastate houses. In association with these impacts, mobility, travel, processing, and logistic operations are severely reduced. In the human dimension, the fishers and fish farmers are directly affected in terms of income loss, destroyed fishing gears, nutritional deficiencies and health impacts, less fishing operations, early or reduced harvest yield, and low market value of products. In the adaptation options, the infrastructure, social, economic, awareness/knowledge, and relevant governance/policy dimensions are needed to address and help mitigate various climate change impacts.

    Ensuring aquatic food security in the Philippines
    Cabral, Reniel; Geronimo, Rollan; Mamauag, Antonio Samuel; Silva, Juan; Mancao, Roquelito; Atrigenio, Michael (National Fisheries Research and Development Institute, 2023-12)
    The human population of the Philippines is expected to reach 158 million by the year 2050, or an increase of 37% relative to 2022. This implies increased demand for aquatic food (or “fish” hereafter). This begs the question of whether the Philippines can meet the expected increase in fish demand. We estimate that even if the Philippines can maintain its current fish production, the Philippines will still require 1.67 million metric tons more fish per year by 2050 to at least maintain its current per capita fish consumption of 34.27 kg per year. Continued mismanagement of inland and marine fisheries will further widen the gap in fish supply. However, we argue that simultaneously rebuilding overfished fisheries, restoring degraded habitats crucial to supporting productive fisheries, addressing current threats to fisheries sustainability, and expanding sustainable marine aquaculture (or mariculture) have the potential to meet future fish demand in the Philippines. Sustainably expanding mariculture requires careful siting and management of mariculture development areas so that mariculture can improve food security without disenfranchising and marginalizing local coastal communities.
    This policy brief is the product of the address delivered by RBC during the 44th Annual Scientific Meeting of the National Academy of Science and Technology, Philippines, last July 2022, with the theme Foresight 2050: Science for a Sustainable Future. We dedicate this work in memory of our friend, Lito Mancao, who championed good governance in the Philippine fisheries and has generously supported numerous fisheries researchers and practitioners.
