| Summary/Abstract |
Turkey relies heavily on imported fossil fuels to meet a significant portion of its domestic energy demand. This has resulted in a rapid increase in the country's Greenhouse Gas (GHG) emissions over the past decade and raised questions about energy security. To address these challenges, Turkey has established several renewable energy targets, including a target to produce 30 percent of domestic electricity from renewable resources, such as wind, solar and biomass, by 2023. The biomass component is set to reach 1000 MWe by 2023. Given Turkey's large agriculture sector, this paper examines whether agricultural residues can play a role in meeting the biomass component of the renewable electricity target. The analysis is carried out at provincial level, using country-specific data and inputs from national experts and focuses on the crop and livestock bioenergy chains. The assessment results illustrate the bioenergy potential at provincial level, and consequently identify which bioenergy supply chains could be most feasible by province. The paper also quantifies the degree to which the selected bioenergy supply chains can contribute to achieving the biomass component of the renewable electricity target.

| Summary/Abstract |
We use a mathematical programming model to examine the impacts of simultaneous implementation of two US biofuel and bioenergy policies on commodity markets and spatial distribution of future cellulosic biorefineries. The key findings based on our numerical simulation are: (1) the number and average annual production capacity of cellulosic biofuel refineries depend on the total renewable fuels mandate; (2) the mix of cellulosic biomass feedstock depends on the assumptions about the production costs of energy crops and the amount of cropland that can be used for energy crops, but regardless of the assumptions crop residues are the primary biomass source to meet the demand for biomass for biofuel production and electricity generation; and (3) the biomass production areas would surround either future cellulosic biorefineries or the existing coal-based power plants to reduce the costs of biomass transportation. These findings have important implications for biorefinery investors and provide valuable policy insights for the selection of Biomass Crop Assistance Program project areas.

| Summary/Abstract |
Farmers can use their own agricultural biomass residues for heat production in small-scale systems, enabling synergies between the district heating (DH) sector and agriculture. The barriers to entry into the Swedish heat market were extremely high as long as heat distribution were considered natural monopoly, but were recently lowered due to the introduction of a regulated third party access (TPA) system in the DH sector. This study assesses the potential impact on greenhouse gas emissions and cost-based heat price in the DH sector when farmers vertically integrate into the heat supply chain and introduce more local and agricultural crops and residues into the fuel mix. Four scenarios with various degree of farmer integration, were assessed using life cycle assessment (LCA) methodology, and by analysis of the heat production costs. The results show that full integration of local farm and forest owners in the value chain can reduce greenhouse gas emissions and lower production costs/heat price, if there is an incentive to utilise local and agricultural fuels. The results imply that farmer participation in the DH sector should be encouraged by e.g. EU rural development programmes.
