This paper aims to outline some of the challenges I perceive to be facing plant protection researchers, industry and users of products and services; challenges that are increasingly a product of ongoing globalisation of trade, increasing concerns about environmental stewardship world-wide and a decreasing trust by society of environmental management, assurances by governments, their agencies, businesses and, in some cases, of the science itself. The origins of plant protection, as a science and an industry, lie with the protection of food and fibre crops. The focus has been on production protection with, initially, relatively little attention to the environmental impacts of most control technologies. As the science and the business of plant protection has matured over the last three or four decades, it has expanded to include recognition of the ongoing needs of production protection, its role in protecting conservation ecosystems, the environmental consequences of production protection products and the societal acceptance or rejection of the environmental impacts of these products. It is this maturing of the approach to plant protection that now presents the greatest opportunity for those working in all aspects of the field, as well as the greatest risks if the increasing complexities in the whole field of food production and protection are not fully recognised. A global context In global terms there is no question that one of the single biggest challenges facing humanity is going to be the maintenance of food supplies over the next 50 years as the global population rises to more than 8.5 billion. However, in a plant protection context, and particularly in terms of New Zealand’s position in the world as a premium food and fibre producer, it is simplistic to focus primarily on the maintenance of production capacity. It is also essential that there be a sharp focus on the maintenance and enhancement of the environmental qualities of foodand fibre-producing agricultural ecosystems, including “down stream”, on land and ocean systems that receive the wastes of our production systems. New Zealand, as a society and an economy, has some unique challenges. These are: • That our economic and social health is very closely tied to the maintenance of a healthy natural resource base, not just in terms of our traditional land uses for agriculture and forestry but also in terms of the expectations of an increasing number of international visitors and our predominantly urban population. • That this natural resource base is a relatively limited one in terms of high quality soils and, increasingly, in terms of high quality water because of competing demands particularly between urban and agricultural horticultural uses in the vicinity of our urban areas. • That while our trading future lies largely in the more affluent world of North America, Europe and Asia, there is limited evidence that these markets are prepared to pay the full ecological cost of production. If one of our keys to wealth generation rests with the ongoing sustainable management of ecological systems, it is essential that we ultimately obtain a return for our products that fully reflects the ecological cost of production, ie, the system must be ecologically sustainable. • For New Zealand it will increasingly be the demands of global consumers for higher
