Customary marine tenure systems and sustainable fisheries management in Papua New Guinea

According to this model, where access to a fishery is free, it is not in the interest of the community to limit their fishing effort. To prevent over‐fishing and eventual destruction of fish stocks, fisheries managers in Papua New Guinea (PNG) have concentrated their efforts on imposing limits on fishing effort. Argues that such methods are bound to fail because they are imposed by outsiders and are alien to the local communities. Argues that customary marine tenure systems have a better chance of success in the management of local fisheries resources because they are community‐based and are derived from kinship and lineage structures. Advocates that, rather than overlooking such systems, governments must strengthen them to enable them to play their role in sustainable fisheries management.

A model of health status was specified in which the main variables were income level, income inequality, the level of savings and the level of education. The model was estimated using a panel data set for 44 countries covering six time periods. The results indicate that income inequality (measured by the Gini coefficient) has a significant effect on health status when we control for the levels of income, savings and education. The relationship is consistent regardless of the specification of health status and income. Thus, the study results provide some empirical support for the income inequality hypothesis.

Facing the stark prospect of a deep recession, the government instituted a stabilisation structural adjustment program. Despite the economic recovery following the remedies, the Papua New Guinea economy is still saddled with problems of law and order, unemployment and a decline in mining exploration and investment.

The results indicate that, in the short-run, unidirectional Granger causality runs from energy to income for India and Indonesia, while bidirectional Granger causality runs from energy to income for Thailand and the Philippines. In the case of Thailand and the Philippines, energy, income and prices are mutually causal. The study results do not support the view that energy and income are neutral with respect to each other, with the exception of Indonesia and India where neutrality is observed in the short-run.

The significant factors affecting perception of the soil erosion problem are age, ethnicity, and extension education, while the significant factors affecting soil conservation effort are perception of the erosion problem, age, ethnicity, and extension education. Contrary to theoretical expectations, economic and physical factors do not significantly affect soil conservation behaviour in this sample of farmers. The resulting implications for soil conservation policy are discussed.
Traditional production activities and resource sustainability

Ecologically sustainable development issues in relation to indigenous people have not been paid much attention following the release of the Bruntland Report in 1987 and the Rio de Janeiro “earth summit” in 1992, which put forward a programme of action for achieving ESD by the year 2000 and beyond. Concludes that traditional methods of production practised by the indigenous societies are inherently sustainable but recognizes that population growth and poor economic prospects could exert pressure on the region’s fragile ecosystem. Efforts must be made to involve local people in resource management and planning, and social justice issues such as land and sea rights, unemployment, and the provision of basic infrastructure need to be resolved.

According to the Environmental Kuznets curve (EKC) hypothesis, environmental quality is high at low levels of economic development. However, as countries develop, environmental quality worsens until it starts to improve at higher levels of economic development. Whereas several empirical papers have tested this hypothesis for both developed and developing countries, this is the first study to address this issue for Pacific Island countries. The results of both graphical and polynomial regression models indicate that an EKC relationship exists for Kiribati, New Caledonia, PNG, and the Solomon Islands. However, this is not the case for Fiji and French Polynesia. The finding of an EKC relationship does not imply that economic growth by itself will solve environmental problems. In order to achieve a significant improvement in environmental quality, there is a need for governments to increase expenditures on environmental management, as well as on public education and awareness.
