    The current issue of Unasylva takes a long look at the relationship of forestry with food security, and asks the question, ''How can forestry development programmes and activities become as relevant as possible in ensuring economic and physical access to food by all people at all times?" In the lead article, M. Hoskins sets out the actual and potential contributions of forestry to food security, and suggests practical strategies for the incorporation of food security components in forestry development activities.

    This report details some species of fish considered appropriate for stocking the Sepik/Ramu Rivers. Fishes thought suitable for introduction have been divided into three categories: Category A (species whose introduction is recommended); Category B (species that are thought to be of particular interest which are presently being evaluated in detail) ; and, Category C (interesting species with longer-term potential). Only category A species are presently recommended.

    This document is prepared for fisheries biologists, managers and administrators concerned with lagoon fisheries and aquaculture. Our main objective is to draw attention to the need for greater understanding of relationships between the hydraulics and productivity of lagoon fish and shellfish. The fishery yields from lagoons vary widely, and, probably, predictably, once such relationships are understood. Furthermore, the productivities of many lagoons could probably be enhanced by hydraulic manipulations, but the hydraulic manipulation is presently risky, except in dystrophic lagoons.

    Depending on land management objectives, plus a host of environmental variables, fire will sometimes be an enemy, at other times a friend; in nearly all cases, however, it will continue to exert a powerful influence on natural resource ecosystems. This being so, consideration of the potential impact (both positive and negative) of fire is essential in all land-use plans and programmes for forestry development.
