    Forests play a central role in climate change mitigation actions, and substitution, that is the use of wood products in place of fossil intensive materials, has been recognized as a potential way to avoid emissions. While there are studies estimating the substitution impact of products, i.e., the avoided emissions, there is a lack of studies integrating market perspectives into substitution estimation. To contribute to this research gap, this study explores the market assumptions of substitution through the theoretical lenses of value chains and microeconomic theory on demand. The objectives are to recognize powerful decision-makers in the value chains, to establish a better understanding for the current state of substitution in the markets, and to explore the determinants of demand of the wood-based products. To limit the scope of this study, the use of pulp-based products was examined in the cases of packaging and textile sectors. Semi-structured interviews with 14 experts were arranged to discuss their views on substitution and demand of the pulp-based products in the chosen sectors. Additionally, a Likert scale was filled at the end of each interview to supplement the interview answers and enable elasticity and cross-price elasticity analyses to examine substitution. The sample of respondents was chosen through the use of snowball sampling and a matrix to recognize potential interviewees. First, the findings of this study suggest that in both sectors, the decision-making power on materials is held by the operators at the end of the value chain whereas the forest sector is located at the beginning of the chain. Second, in both sectors, there is willingness to find more sustainable material solutions, but the tools for this are lacking. In the case of packaging sector, the barrier capacities of plastic are unattainable with fiber-based materials, meaning that reducing plastic use does not always imply switching the feedstock itself. In the textile sector, the production of wood-based textile fibers is not yet scaled enough for it to compete with similar materials. However, the analysis of elasticities indicates that some substitution can be expected in both sectors. Third, a number of important determinants of demand were identified, yet no single factor could be identified as the most important one. This study concluded that there is room to improve the market assumptions for substitution impact estimation. In packages, the market preferences of fiber-based packaging in some uses give a rise for interpretational issues, while plastic reduction goals do not always imply switching to wood feedstock. In textiles, the new man-made cellulosic fibers (MMCFs) are expected to mostly substitute for viscose and fill the cellulosic gap from stagnating production of cotton instead of substituting for synthetic fibers. To conclude, it is central to integrate market data and concepts better into future substitution impact analyses to facilitate more realistic estimates.

    Potatoes (Solanum tuberosum) are an important crop for the food security of developing countries, and farmed area of potatoes in those countries is expanding constantly. It would be important to solve the problems of potato production and distribution in Tanzania. The research problem of this thesis was to examine the value chain of potatoes in Tanzania and factors that prevent the industry’s development. Furthermore, the aim was to evaluate agricultural policies affecting potato value chain and illustrate the present state of potato production and marketing chain in contrast to other crops. The research was conducted by executing 14 semi-structured expert interviews in Tanzania in June 2011. In addition to this, two researchers answered in written form. The interviewees were researchers, agricultural extension officers, managers of nongovernmental organisations, dealers of agricultural market place, a agricultural project coordinator, and officials from the ministry of agriculture as well as from the ministry of trade and marketing. Theoretical framework in this thesis is based on structure-conduct-performance (SCP)-paradigm. Moreover, the basic conditions and public policy of the industry are to be found out. The results indicate that the government does not affect much to the operation nor the development of the potato value chain: potato is not the government priority in Tanzania. On the other hand, there are no straight policy measures or institutional barriers that are hindering the conditions of smallholders or other actors in the chain, either. Bad seed quality is most likely the biggest challenge on the production part. Difficulties to get loans and the lack of investments and farmers’ groups are hindering the production. The biggest infrastructural issue is poor road network in the countryside. As a suggestion based on the results is that two instances should be created: a national potato board and marketing centres in the villages. The prerequisite for those instances to be possible to establish and function well is the activity of the government. Especially to operate the market centers properly, it is important that the village leaders and farmers would be committed to its activities.
