Abstract

A descriptive type of study on the impacts of typhoon Nona was conducted from August 2016 to January 2017 in the selected coastal barangays of Biri, Lavezares, Rosario, and San Jose, (Biri-LaRoSa) which form part of the Biri-LaRoSa seascape and landscape of the province of Northern Samar. It focused on the impacts of the typhoon to the coastal environment and its socio-economic effect. Actual field sampling was done for the quantitative assessment of the coastal ecosystems. Participatory Resource Appraisal (PRA) tools were used for the qualitative assessment. Biri area has a total of 23.5% partially damaged trees and 9.4% totally damaged trees in the mangrove ecosystem; 51.7% damage to the seagrass beds; and 79.1% damage to the corals. Lavezares area has a total of 32.5% partially damaged trees and 9.5% totally damaged trees in the mangrove ecosystem; 47.9% damage to the seagrass beds; and 76.5% damage to the corals. Rosario area has a total of 33% partially damaged trees and 5.8% totally damaged trees in the mangrove ecosystem; 47.6% damage to the seagrass beds; and 36.1% damage to the corals. San Jose area has a total of 39.6% partially damaged trees and 7.6% totally damaged trees in the mangrove ecosystem; 48% damage to the seagrass beds; and 56.8% damage to the corals. Typhoon Nona greatly affected the ecosystems in the sampling sites and in turn affected the socio-economic conditions of ‘the locals, especially those who are dependent on the coastal resources both for food and income. Both results of the PRA and actual field assessment support this claim.

Highlights

The Biri-Larosa Protected Landscape/Seascape (BLPLS) was proclaimed as a protected area under the category of Protected Landscape/Seascape by virtue of Presidential Proclamation No 291 on April 23, 2000 and RA 11038 (E-NIPAS) on account of its famous geological wonders known as “Rock Formations”, tropical mangroves and excellent display of benthic life forms

Northern Samar in terms of the level of visible damages caused by the typhoon in the mangrove ecosystem, sea grass beds and coral reef communities; 2) determined the socio-economic impacts of typhoon Nona in the coastal areas of Biri-LAROSA Northern Samar; and, 3) determined the interventions made after the typhoon

Summary

Introduction

The Biri-Larosa Protected Landscape/Seascape (BLPLS) was proclaimed as a protected area under the category of Protected Landscape/Seascape by virtue of Presidential Proclamation No 291 on April 23, 2000 and RA 11038 (E-NIPAS) on account of its famous geological wonders known as “Rock Formations”, tropical mangroves and excellent display of benthic life forms. Impacts of Typhoon Nona in The Coastal Areas of Biri-Larosa. It harbors interesting animals such as insects, bats and birds that describes the site as one of the Key Biodiversity Sites (KBA 129). Tropical storms (hurricanes, cyclones, and typhoons) are extremely destructive phenomena. They cause considerable damage to life and property around the globe due to the effects of strong winds, heavy rains, and tidal surges (Glantz, 2003)
