Integrating climate change hazard analysis into value chain analysis: Elevating evidences in fisheries into practice

Abstract

© 2018, International Society for Southeast Asian Agricultural Sciences. All rights reserved. This paper offers an alternative method of estimating the economic impacts of climate change hazards on individual players and on the entire value chain using primary data that were collected in the months of 2017 from affected tilapia value chain in Pampanga and siganid value chain in Pangasinan. The paper (1) identifies the main features of a fisheries value chain under a climate change hazard scenario, (2) builds a consistent value chain accounting framework, (3) reflects the changes in operation and corresponding value addition arising from the adaptive strategic measures, and (4) assesses the net income accruing to individual players or groups. Direct and indirect effects, and defensive expenditures, were also calculated. Reduced production because of temperature rise was felt by tilapia hatchery operators (46%) and pond operators (32%) while broker-traders experienced 14% reduction in volume bought from growers inside the chain and had to outsource 21% to meet the requirement of wholesalers. For siganid fishers, Typhoon Lando caused a 2.5% reduction in the selling price, a 34% reduction in volume (about PHP 1,340 per fisherman), and additional defensive expenditure of PHP 3,461. Due to the cascading effects of lower catch, the wholesale and retail segments of the siganid value chain suffered an indirect cost of PHP 189,000 and PHP 43,350, respectively, as well as an incremental marketing cost for wholesale (PHP 2.68/kg) and retail (PHP 1.08/kg).
