Climatic and environmental records from low, middle, and high latitude ice cores greatly increase our knowledge of the course of past events. This historical perspective is essential to predict climatic oscillations, dominated as they may be by increasing greenhouse gas concentrations. Forcing factors, internal and external, that have operated in the past will continue to influence the course of events.

The status of marine fisheries research and development in India is discussed and the need for a high power national body to coordinate these activities is stressed. Priority areas for research and development have been outlined. It has been stressed that the strategy should be to achieve a production target of 3 million tonnes on the capture fisheries front (2.5 million tonnes from the inner shelf and 0.5 million tonnes from the outer shelf and slope areas) and 1 million tonne through aquaculture by 2000 AD.

Small-scale and artisanal fisheries contribute about two-thirds of the global fish production destined for direct human consumption. They also accommodate over 90 per cent of those who make their living from fisheries. Women comprise at least half the workforce in small-scale fisheries. Despite the important contributions made by small-scale fisheries to poverty eradication and food security, small-scale fishers and fishworkers continue to be marginalized at different levels. It is in this context that the Committee on Fisheries (COFI) of the Food and Agriculture Organization of the United Nations (FAO) has developed the Voluntary Guidelines for Securing Sustainable Small-scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines).

Fish farmers in Laguna de Bay are facing conflict of the use of the lake which is being tapped as freshwater source for domestic use. The article documents the perspectives of some fish farmers and researchers on the development of carp aquaculture industry in the lake. According to carp farmers and researchers, the industry is profitable; however, marketing, post harvest and processing strategies remain poor. In this regard, Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD) should be the frontline ally of carp growers since SEAFDEC/AQD developed the technology for lake culture.
