Fish provides more than 4.5 billion people with at least 15 % of their average per capita intake of animal protein.Fish's unique nutritional properties make it also essential to the health of billions of consumers in both developed and developing countries. Fish is one of the most efficient converters of feed into high quality food and its carbon footprint is lower compared to other animal production systems. Through fish-related activities (fisheries and aquaculture but also processing and trading), fish contribute substantially to the income and therefore to the indirect food security of more than 10 % of the world population, essentially in developing and emergent countries. Yet, limited attention has been given so far to fish as a key element in food security and nutrition strategies at national level and in wider development discussions and interventions. As a result, the tremendous potential for improving food security and nutrition embodied in the strengthening of the fishery and aquaculture sectors is missed. The purpose of this paper is to make a case for a closer integration of fish into the overall debate and future policy about food security and nutrition. For this, we review the evidence from the contemporary and emerging debates and controversies around fisheries and aquaculture and we discuss them in the light of the issues debated in the wider agriculture/farming literature. The overarching question that underlies this paper is: how and to what extent will fish be able to contribute to feeding 9 billion people in 2050 and beyond?

Increasingly, developing nations which are land rich are sanctioning the sale or transfer of user rights of large tracts of farmland for foreign investment. While this issue is of relatively recent origin, caused in large measure by the recent global food crisis and related to desires by food importing countries to have greater control over their food supply, the impact on food security could be very significant. Because of the newness of the matter, most of the available evidence is found outside traditional academic literature. Poor, smallholder farmers without formal land titles currently occupy much of the land sold in these transactions, threatening the internal food security of the lessor state. Factors driving the global acquisition of land include development aid shortfalls, the global food crisis, the burgeoning middle class in middle-and high-income nations, and the increasing acceptance of biofuels as a viable alternative source of fuel by governments of these nations. The risks associated with the global acquisition of land on food security of the seller country are manifold. This article reviews the current literature available on the subject and makes policy suggestions for equitable investment and benefit-sharing for all stakeholders. Opportunities and risks abound but if the risks are mitigated, then the global acquisition of land has the potential to be an unparalleled development opportunity for lessor states.
