Environmental Impact Assessments: Suitable for supporting assessments of biofuel sustainability?
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The European Union requires that 10% of the energy in the transport sector shall come from renewable sources by 2020. In addition, biofuels used for transport need to fulfill certain sustainability requirements set out in the Renewable Energy Directive (RED). To meet these requirements, the EU will need to produce and import large amounts of sustainable biofuels. Therefore, there is a need for ways to verify the sustainability of imported biofuels, so that unsustainable biofuels can be avoided. One strategy may involve analyzing Environmental Impact Assessment (EIA) reports (EIRs) conducted for specific biofuel projects. For EIRs to be useful as such information sources they need to be sufficiently comprehensive in relation to the RED but also sufficiently reliable.In this study, 19 biofuel project EIRs are analyzed with respect to how they cover the RED sustainability considerations. In addition, EIA legislation, requirements, quality, and enforcement are discussed to determine not only whether EIRs can be sufficiently comprehensive, but also sufficiently reliable for supporting information to studies intended to assess the sustainability of biofuels, from an RED perspective.Notable differences between EIRs for different types of projects were found. EIRs for projects including both plantation establishment and the construction of a biofuel plant had better RED coverage than EIRs for projects including either the plantations or the biofuel plant. As might be expected, EIAs for “plantation projects” generally leave out features related to biofuel processing, and EIAs for “biofuel plant” projects generally leave out features related to feedstock production.In general, EIA legislation is insufficient and most target countries seem to have rather low potential to enforce legislation. Several additional EIA-related problems need to be overcome in order for EIRs to be regarded as sufficiently reliable information tools.

Can India’s wasteland be used for biomass plantations?
- 2015
-
Rapport (populärvet., debatt m.m.)abstract
- How much of India’s vast wasteland can be used for growing plants such as eucalyptus and Jatropha? As land demands have increased, the sustainable use of marginal lands has become increasingly important. In India about 47 million hectares, or 15 percent of the total geographical area, is classified as wastelands. Here we assess the climate and land quality requirements of eucalyptus, a commonly used plantation tree, and Jatropha, a much-discussed biodiesel crop. We find that roughly half of the degraded lands are suitable for growing eucalyptus and/or Jatropha.

Carbon Sequestration Versus Bioenergy: A Case Study From South India Exploring The Relative Land Use Efficiency Of Two Options For Climate Change Mitigation
- 2010

Tidskriftsartikel (refereegranskat)abstract
- This case study has been carried out as a comparison between two different land-use strategies for climate change mitigation, with possible application within the Clean Development Mechanisms. The benefits of afforestation for carbon sequestration versus for bioenergy production are compared in the context of development planning to meet increasing domestic and agricultural demand for electricity in Hosahalli village, Karnataka, India. One option is to increase the local biomass based electricity generation, requiring an increased biomass plantation area. This option is compared with fossil based electricity generation where the area is instead used for producing wood for non-energy purposes while also sequestering carbon in the soil and standing biomass. The different options have been assessed using the PRO-COMAPmodel. The ranking of the different options varies depending on the system boundaries and time period. Results indicate that, in the short term (30 years) perspective, the mitigation potential of the long rotation plantation is largest, followed by the short rotation plantation delivering wood for energy. The bioenergy option is however preferred if a long-term view is taken. Short rotation forests delivering wood for short-lived non-energy products have the smallest mitigation potential, unless a large share of the wood products are used for energy purposes (replacing fossil fuels) after having served their initial purpose. If managed in a sustainable manner all of these strategies can contribute to the improvement of the social and environmental situation of the local community.

Jatropha cultivation in southern India: assessing farmers experiences
- 2012
-
Ingår i: Biofuels, Bioproducts and Biorefining. - : John Wiley and Sons. - 1932-104X .- 1932-1031. ; 6:3, s. 246-256

Tidskriftsartikel (refereegranskat)abstract
- Together with 106 farmers who started growing Jatropha (Jatropha curcas L.) in 20042006, this research sought to increase the knowledge around the real-life experience of Jatropha farming in the southern India states of Tamil Nadu and Andhra Pradesh. Launched as an alternative for diesel in India, Jatropha has been promoted as a non-edible plant that could grow on poor soils, yield oil-rich seeds for production of bio-diesel, and not compete directly with food production. Through interviews with the farmers, information was gathered regarding their socio-economic situation, the implementation and performance of their Jatropha plantations, and their reasons for continuing or discontinuing Jatropha cultivation. Results reveal that 82% of the farmers had substituted former cropland for their Jatropha cultivation. By 2010, 85% (n = 90) of the farmers who cultivated Jatropha in 2004 had stopped. Cultivating the crop did not give the economic returns the farmers anticipated, mainly due to a lack of information about the crop and its maintenance during cultivation and due to water scarcity. A majority of the farmers irrigated and applied fertilizer, and even pesticides. Many problems experienced by the farmers were due to limited knowledge about cultivating Jatropha caused by poor planning and implementation of the national Jatropha program. Extension services, subsidies, and other support were not provided as promised. The farmers who continued cultivation had means of income other than Jatropha and held hopes of a future Jatropha market. The lack of market structures, such as purchase agreements and buyers, as well as a low retail price for the seeds, were frequently stated as barriers to Jatropha cultivation. For Jatropha biodiesel to perform well, efforts are needed to improve yield levels and stability through genetic improvements and drought tolerance, as well as agriculture extension services to support adoption of the crop. Government programs will -probably be more effective if implementing biodiesel production is conjoined with stimulating the demand for Jatropha biodiesel. To avoid food-biofuel competition, additional measures may be needed such as land-use restrictions for Jatropha producers and taxes on biofuels or biofuel feedstocks to improve the competitiveness of the food sector compared to the bioenergy sector.

Konferensbidrag (refereegranskat)abstract
- In India expectations have been high on production of biodiesel from the oil-crop Jatropha. Jatropha is promoted as a drought- and pest-resistant crop, with the potential to grow on degraded soil with a low amount of inputs. These characteristics encourage hope for positive environmental and socio-economic impacts from Jatropha biodiesel production. The purpose of this study was to explore the performance of Jatropha biodiesel production in Southern India, to identify motivational factors for continued Jatropha cultivation, and to assess environmental and socio-economic impacts of the Jatropha biodiesel production. 106 farmers who have or have had Jatropha plantations were visited and interviewed regarding their opinion of Jatropha cultivation. The result indicates that 85 percent of the farmers have discontinued cultivation of Jatropha. The main barriers to continued cultivation derive from ecological problems, economic losses, and problems in the development and execution of the governmental implementation of the Jatropha programme. The Jatropha characteristics were overrated, and the plantations failed to provide income to the farmer. A common factor for the farmers who continued Jatropha cultivation was that they had the economic means to maintain non-profitable plantations. As the Jatropha programme was not as successful as expected, the expected positive environmental and socio-economic impacts have not been realized.

Multifunctional biomass production systems - an overview with presentation of specific applications in India and Sweden
- 2008
-

Tidskriftsartikel (refereegranskat)abstract
- This perspective discusses multi-functional biomass production systems, which are located, designed, integrated and managed so as to provide specific environmental services, in addition to biomass supply. Besides discussing the general concept and outlining a range of different possible applications, we present in somewhat more detail specific applications of such systems for the cases of Sweden and India. The overall conclusion is that the environmental benefits from a large-scale establishment of multi-functional biomass production systems could be substantial. Given that suitable mechanisms to put a premium on the provided environmental services can be identified and implemented, additional revenues can be linked to biomass production systems and this could enhance the socioeconomic attractiveness and significantly improve the competitiveness of the produced biomass on the market. The provision of additional environmental services also contributes to local sustainable development, which is in many cases a prerequisite for local support for the production systems.
