Analisis Ekonomi Keterkaitan Ekosistem Mangrove dengan Sumber Daya Udang

Mangroves provide a wide range of ecosystem services. Therefore, the existence of mangrove ecosystem needs to be maintained ecologically, economically and socially. This study aimed to identify the mangrove ecosystem linkages with shrimp. Data used in this study were primary and secondary data to generalize a case study on shrimp and mangrove ecosystem linkages in Pabean Udik Village Indramayu regency. The economy analysis of the relationship between mangroves and shrimp used mathematical equations by Barbier and Ivar (1994). Mangrove ecosystem linkage with shrimp seen from the marginal productivity of mangrove area (MPM) was 153.454 tons per km2, while the marginal productivity of fishing effort (MPE) wais 0,305 tons per trip using the shrimp catching boat. The study showed that the decline in mangrove ecosystems area would affect the decline in shrimp production, and the increase in mangrove ecosystems area would affect the incrase in the number of shrimp production.

Sustainable frugality through EIA: role of socio‐ecological linkages in poverty alleviation

PurposeThe purpose of this paper is to bring out the shortcomings of the EIA model imported from developed countries when it is assessed for its focus on poverty alleviation in a developing nation (India) and to suggest improvements in the existing framework.Design/methodology/approachThe paper explores the current performance of EIA process in India, critically analyses the philosophy of continued sidelining of environmental protection in favour of unrestricted economic growth in the light of evidence regarding growing inequality.FindingsThe paper finds that for the proponent driven EIA model to contribute towards poverty alleviation, a new “socio‐ecological linkage document” is needed. This will bring out the fragile linkages that marginalized communities have with their local ecosystems and can be prepared with the help of local ecological knowledge. A framework to integrate the socio‐ecological linkage document into the EIA‐SEA‐SA domain is presented.Practical implicationsThe paper shows that the supportive framework of generating the “socio‐ecological linkage document” has the potential to enhance the EIA‐SEA‐SA process in terms of ensuring that plans, policies, programs and projects are sensitive to the need of ecosystem dependent poor.Originality/valueThe paper proposes a framework to support the alternative thinking that poverty alleviation can be enhanced through preservation of ecosystem linkages, in contrast to the modern paradigm of economic growth at the cost of ecosystem.

Using Sciences to Improve the Economic Efficiency of Conservation Policies

In the last 20 years, both public and private expenditures on resource conservation and environmental protection have increased dramatically. However, there are numerous technical and political barriers to the efficient use of conservation funds. This paper discusses some of these barriers and approaches to overcoming them. It argues that ecosystem complexities such as threshold effects, ecosystem linkages, and spatial connections often mitigate against politically palatable criteria for resource allocation. Ignoring these complexities is likely to result in substantial efficiency losses. While challenges are daunting for the efficient management of conservation investments, payoff is potentially high for the use of sciences.
