Traditional first-generation biofuel feedstocks (e.g. maize, soybeans) are being questioned in favour of more environmentally-sound second-generation biofuel feedstocks (e.g. trees, perennial grasses). However, as an emerging industry, the commercial use of second-generation biofuel feedstock sources has several challenges to overcome. One of these challenges is landholders’ willingness to plant second-generation crops on their farms. To understand the landholders’ perspectives, this thesis used a conceptual framework based on adoption of innovation and diffusion theory, and applied this framework to a case study in the Central West region of New South Wales, Australia. The research questions addressed were: 1) what factors underlie landholders’ willingness to plant bioenergy tree crops, 2) what are the landholders’ preferences in the design of contracts for planting these trees, and 3) what are the potential pathways to build a critical mass of tree growers for bioenergy. A mixed methods approach was used involving quantitative analytical tools (e.g. tobit and logit regressions, choice modelling, and break even analysis) and qualitative analytical tools (e.g. integrated analysis). Tobit and logit regression models estimates revealed three key traits that positively influence the decision to plant second-generation biofuel feedstocks: 1) the landholder’s proportion of unproductive land, 2) the landholder’s membership in farming related organisations, and 3) the landholder’s experience with planting blocks of trees. Conversely, the landholder’s older age-squared would negatively influence their decision to plant second-generation biofuel feedstocks. The choice model estimates revealed that landholders who had already planted blocks of trees would be less likely to need a flexible contract for planting trees as energy crops, while landholders with larger proportions of unproductive land would prefer higher returns. This thesis concludes that for a second-generation bioenergy industry to emerge, a critical mass of biomass growers needs to be secured; this can be achieved by developing interlinked pathways that include: 1) supportive policies, 2) local support and an innovation champion, and 3) corporate support and/or a potential biomass buyer or investor. This research has identified critical pathways that can be developed to progress the bioenergy industry in Australia. The proposed pathways can be used to explore actors’ participation and their potential roles in scaling up, and to better understand the process of building critical mass for a second-generation bioenergy industry.1 vol.application/pdfen-AUAuthor retains copyrightcritical massbioenergyadoption of innovationnew value chainstree plantingtree growers201610.25911/5d51441529f43
