A multidisciplinary team of scientists (Appendix 1) examined 10 of the 16 environmental benchmarks that are tracked by the Oregon Progress Board. The intent of the environmental benchmarks is to provide a fair assessment of the status and trends of Oregon's environmental health. The scientists were asked to clarify benchmark...
This study examines income generation potential and resource- use efficiency of aquaculture farms in Nigeria. A total of 120 aquaculture farms were sampled. Using gross margin (GM) analysis, the result shows that, all the sampled farms were able to cover their total operating expenses with an average GM > 200,000...
The Lower Mekong Basin (LMB) is shared by Thailand, Lao PDR, Cambodia and Vietnam and provides a range of natural resources and services which are important to the national economies (e.g. water for hydro-electric power) and also to the livelihoods of the people (e.g. fishing and farming opportunities) in the...
According to the UN's Food and agicultural organisation (FAO, managing fishing capacity is a core elemnt to aceive sustainable fisheries. Here, FAO highlight the long term need to avoid unprofitable overcapacity; an adaptation which increase the pressure on fish resources, fisheres are marginalized economically, allocation conflicts among fishermen and high...
The Mekong River Delta plays an essential role to Vietnam’s economy in terms of both rice and fish production. Annual flooding water and a rich level of aquatic resources strongly affect about 10 million
local people, as well as extend beyond the boundaries of wetland itself. Flooding water and wild...
Developing an allocation scheme for distributing rights amongst fishing nations remains one of the major obstacles to the development of stable cooperative arrangements to exploit international fish resources.
A great deal of effort has been devoted over the years to finding a durable solution to the allocation problem, both at...
In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...
This paper identifies economic institutions related to the small-scale craft fishery in southern Sri Lanka, and assesses their importance for the livelihood of the fisher households as well as for resource conservation. Income from small-scale craft fishing is generally uncertain because of seasonality and uncertainty of the marine fish resource,...
The rapid growth of crocodile farming in Cambodia has created a domestic market for snakes as a food supply that operates alongside the international trade of skins and live animals. In times of fish scarcity small-scale fishers living on Tonle Sap Lake participate in what has been shown to be...
According to conventional economic wisdom the economically more efficient technology will always outcompete the less efficient. This hypothesis has usually been taken to hold for the exploitation of common pool renewable natural resources such as fish stocks. This paper claims that, while this is not necessarily false, it may be...
