The Programme includes three components relating to the origin of partners: Estonia, Finland, Latvia and Sweden. These Programme components are the Central Baltic Programme, the Southern Finland–Estonia Sub-programme and the Archipelago Islands Sub-programme. The Foodweb-project is a part of the Central Baltic Programme and its budget is about 1.5 million Euros. The project focuses on creating attractive and dynamic societies and on improving living conditions and social inclusion. The partners in the Foodweb-project are MTT Agrifood Research Finland, as the lead partner, the University of Tartu, the science exhibition centre AHHAA, the Finnish Environment Institute and the University of Latvia. The Central Baltic programme extends to over 180 000 square kilometres of the Baltic Sea catchment area, which is home to over 9.9 million people. This covers approximately 11.7 % of the population of the Baltic Sea drainage basin. 50.6 % of the population of Finland and 85 % of the total population of Latvia live in the central Baltic IV A project area. The project area includes all the inhabitants of Estonia and 42 % of the population of Sweden. Finland, Estonia and Latvia take part in the Foodweb-project in order to collect up-to-date information for a common database that will encourage sharing of information about food consumption and food related risks, as well as centralising information about the environmental effects of food production on these areas. The information about the food situation in Sweden is also collected and results of hazardous compound analysis and information about the characteristics of these compounds collected in Sweden will also be used in this project. About the Baltic Sea The Baltic Sea is a small and relatively shallow brackish body of water located in northern Europe. It is the second largest brackish water basin in the world and is also considered to be the most polluted. The catchment area of the Sea is large, over 1 600 000 km2, and because the volume of water is small (20 000 km3) due to the shallowness (average depth 55 m), the Sea is very sensitive to pollution. The salinity of the water changes at different depths, being greatest in the Danish Straits close to the Atlantic, from where the irregular saltwater pulses enter the Baltic Sea. The salinity decreases farther away from the influence of the Atlantic Ocean, being lowest near the Bothnian Bay. Due to the freshwater runoff near the coast, surface salinity increases towards the bottom and decreases when measured near the coastline. Because of the low salinity, both fresh water and marine species can adapt to life in the Baltic Sea. Low salinity also makes the Baltic‟s unique ecosystems sensitive to changes resulting from human activity. One of the biggest problems is accelerating eutrophication caused by nutrient runoff. The Sea is also vulnerable to pollution caused by harmful compounds resulting from human activity. Eutrophication also increases hypoxia, oxygen depletion, which already occurs on a regular basis in the Baltic Sea bottom waters. The food production chain is one the most resource demanding and polluting sectors, and a large user of energy that causes not only eutrophication, but also global warming and marine pollution. The whole food production chain from agriculture to preservation, distribution, preparation and waste management consumes a considerable amount of not only energy, which contributes to total CO2 emissions, but also nutrients and chemicals harmful to the marine environment and its associated species. Such compounds accumulate in the food chain and in particular species. For example, the Baltic Sea herring and large MTT RAPORTTI 34 3 predatory fish species in the freshwaters exceed the safety limits for harmful chemicals and should not be consumed more often than few times a month. In order to improve the state of the Baltic Sea and maintain the food originating from the Sea as pure as possible, various actions need to be taken. Project objectives The main objective of the Foodweb-project is to raise public awareness about the links between food quality and food origin, focusing on the Baltic Sea and its surroundings. Emphasis is placed on the life cycle of food and the biological cycles: the food web and related biogeochemical pathways. The relationship of people, food and environment will be made obvious and interpreted in terms of the impact of the state of the environment on our food and safety and, vice versa, human impact on the environment related to production of food and in treating residues from the food chain. The final aim is mutual understanding and self-efficacy in risk management. The relationships between extensive industrial land use, decreasing potential of ecosystem services in the project area, growing pressure for safer food production areas, food safety in terms of pollutants and related risks, and the challenges of responsibility in risk management set by the public for the food chain, will be the driving forces communicated via various target groups. Consumers can influence the quality of the Baltic watershed through changes in land use and environmental deposition, and they can have an impact on the environmental status of the Sea. Consumers need to be aware of the risks associated with food choices and learn how to minimise them. In addition to the substantive objectives, the methodical objectives are a) close R&D collaboration throughout the region and regional food supply-demand chains, b) opening of sources of data for the whole food chain partnership and regionally for extensive public use, c) building new tools to combine and interpret environmental impacts and environment-based risks for food consumers, d) making a joint effort to build up food choice models for mutual use and e) identifying a mutual focus on knowledge based facilitation for an exhibition centre. The final methodological aim is a renewed cross-border culture for an environmentally-aware and risk-alert food strategy for the Baltic Sea food shed. The long-lasting impact strived for will be realised by focusing the informational efforts on young families and schools. The project will be strengthened by building partnerships among food chain stakeholders and mutual cooperation throughout the region with help of NGOs. This is a conceptualisation study for answering the questions 1) What are the volumes of food produced and consumed in the area? 2) Which food material flows are important for food system sustainability and environment-based risks? 3) Which key groups of consumers are at risk? The surveys will be performed through collaborative networks and analysed by MTT, SYKE and the Universities of Tartu and Latvia. For hazardous compounds, the baseline for exposure and pathways will be studied by SYKE based on existing reviews and monitoring data (e.g. HELCOM 2010). The baseline will include total exposure to humans from dietary and non-dietary sources. The possibility to use existing methods for combining risks from contaminants in the decision context will be reviewed. Working hypotheses for databases will be formulated on the basis of the previous feasibility study and a pre-study will be initiated on a) current state recommendations for food, b) key contaminants and their health. Population structure in the area The project area covers the southern parts of Finland, the whole of Estonia and in Latvia the capital Riga, as well as Pieriga and Kurzeme regions located on the western coast of the country. The distribution of population in all three countries is concentrated in the main towns, and in Finland and Latvia also along the coastal areas for cultural and agricultural reasons. The total population of Finland is 5.4 million people and of Latvia 2.2 million. The population of Estonia is the lowest of the partner countries, at approximately 1.3 million people. In Finland and Estonia women represent slightly more than half of the population, but in Latvia women outnumber men by almost 8 %. There is also some variation in household sizes among the countries, ranging between 2.48 and 2.08 people and being smallest in Finland and largest in Latvia. The number of single households exceeds the average account for Europe only in Finland and Estonia, but in Latvia more than 18 % of households are of single women.
