Abstract

Ecosystem resilience is the capacity of ecosystems to tolerate disorders without collapsing into different circumstances qualitatively controlled by a different set of processes. A robust ecosystem is one that can withstand shocks and rebuild itself when necessary. This study aims to identify the value of use-based economy and non-use value of current economy; calculating the total economic value of mangrove resources; and provide suggestions and recommendations based on observations in Timbulsloko, Sayung, Demak. The method used is economic valuation with total economic value technique. The sampling technique used non-probability and purposive sampling method. The results showed that the direct use value of mangroves was utilized by fisherman, fish pond farmers, branjang catchers, oystercatchers, trap makers, shop owner, grilled fish makers and shrimp chip makers. Indirect use value was derived from function as the breakwater, beach belt and hybrid engineering. Existing value was not less than 10 % of the direct use value. The total economic value was Rp. 6,361,430,639/year or about Rp. 202,335,580.1/ha/year. It is need to improve the community awareness to mangrove ecosystem and to the role of breakwater in order to reduce risk disaster and to develop an ecotourism in the area.

Highlights

Indonesia is the country with the largest mangrove level in Asia, contributing about half the regional level of the mangrove area

The mangroves ecosystem provides direct use value which was utilized by the fisherman, fish pond farmers, branjang catchers, oyster catchers, trap makers, shop owner, grilled fish makers and shrimp chip makers

Summary

Introduction

Indonesia is the country with the largest mangrove level in Asia (and in the world), contributing about half the regional level of the mangrove area. Other Asian countries with significant levels of mangroves are (in the order of mangroves) of Malaysia, Myanmar, Bangladesh and India, which, together with Indonesia, account for more than 80 % of the total area of mangrove forests in Asia [1]. The mangrove ecosystem is one of the most threatened on the planet. Mangroves are becoming smaller and more fragmented, important ecosystems for goods and services will be reduced or lost.
