Innovation is receiving increased attention among policymakers as a means of addressing sustainable economic development challenges. However, a range of factors such as inappropriate physical and knowledge infrastructures, incoherence of institutional frameworks, or lack of specific capabilities may have a negative impact on the functioning of the agricultural innovation system. The purpose of this paper is to apply a comprehensive innovation systems analytical framework, reconciling analyses of systemic structures, functions, failures and merits of innovation systems to assess and compare the performance of the agricultural innovation systems of Scotland and the Netherlands. To achieve this an analytical framework was drawn up based on the available literature, and through a process that included document analysis and a series of semi-structured interviews and workshops with experts in the two countries the agrifood sectors were empirically assessed. In both countries, systemic failures in terms of actors’ interactions and competencies as well as market and incentive structures were revealed. However, differences emerge between the two countries that appear to relate more to social and cultural (soft institutions) differences rather than the formal legal and regulatory frameworks (hard institutions)

Schoot Uiterkamp; P.W. Gerbens-Leenes;These days, sustainability is a key issue for many private companies that address their sustainable corporate performance (SCP). The perspective is essential for their license to operate and forms the basis for business principles and practices. The lack of internationally accepted reporting standards on what, when and where to report makes it difficult to assess sustainability, however. Moreover, measuring tools providing information on SCP are only the first step towards sustainability. To prevent negative effects of operations being transferred from one company to another, the second step is the development of a system-based approach for all companies that contribute to an end product. This paper presents the findings of a study about the use of environmental indicators for food production and proposes a measuring method for environmental sustainability in food production systems. The study shows that environmental SCP often focuses on events at a local level. The enormous number of indicators found in the literature generates too much data that often provide no additional knowledge on the environmental sustainability of a system. Moreover, although environmental research has addressed many aspects of sustainability, it has often ignored interactions. Overall environmental implications of food production are therefore poorly understood. The proposed measuring method uses three indicators that address global environmental issues: the use of energy (from both fossil and renewable sources), land and water. The systemic approach can calculate trade-offs along supply chains that make up a production system. The use of the method implies an extension of environmental SCP towards the overall performance of a production system. The final outcome is expressed in three performance indicators: the total land, energy and water requirement per kilogram of available food. For companies, the data generated can be used to compare trends over time, to compare results with targets and to benchmark a company against others. For consumers, data can be used to compare the environmental effects of various foods. The method is also applicable to other business sectors. The study is part of a multidisciplinary project on the scientific modeling and measuring of SCP involving economic, social and environmental dimensions. Acceptance of the measuring methods developed may be a powerful contribution towards creating sustainable business practices. (C) 2003 Elsevier B.V. All rights reserved.

It is well known that a unilateral CO2 abatement policy in one region may cause CO2 emissions to increase in non-abating regions because of the relocation of CO2-intensive firms and because of energy market effects. If, however, the CO2 mitigation policy induces energy-saving technological innovation in the home region and this innovation can freely spill-over to energy users abroad, carbon leakage may be offset by induced efficiency gains in foreign firms. In this paper we develop a simple mathematical model of carbon leakage and technological spillovers and perform numerical simulations with an adjusted CGE model to illustrate the potential importance of international technology spillovers. We show that carbon leakage can become negative at moderate levels of technology spillover.

Crescenzi; Aijie Wang; Raffaele Liberatore; Cristiano Varrone; Cristiano Varrone;Abstract The worldwide energy demand has been continuously increasing, thus requesting more sustainable alternatives to the rapidly depleting fossil fuels. Therefore, biofuels such as hydrogen, bioethanol and biodiesel are gaining more importance as a renewable and pollution-free solution, which might give a significant contribution to the future energy mix. In recent years, the exponential growth of biodiesel production has led to a glycerol glut, however, according to some authors, crude glycerol might represent a suitable, abundant and low-priced feedstock for fermentation technologies. In this study we performed an energetic and economic assessment of an innovative process, which is under development in our lab, for the bioconversion of crude glycerol into ethanol and hydrogen. Ongoing experiments showed the possibility to reach at least 26 g/L of ethanol, together with 9 L of hydrogen, in non-sterile conditions and without nutrient supplements. Since kinetics and ethanol concentration need to be further improved, we performed this study with a view to evaluate the possibility of reaching economic viability. Results showed that with 26 g/L of ethanol and a retention time as high as 120 h, the calculated energy cost would be about 0.019 €/kW hth and 0.057 €/kW hel, considering the contribution of both, hydrogen and bioethanol. Moreover, bioethanol cost would be as low as 0.21 €/L, even without taking into account the possible hydrogen revenues. These results are very promising and suggest that the process has reasonable chances to achieve economic viability, thus deserving further attention. The procedure followed in this work provided a realistic and concrete target to pursue in the future lab experiments, in order to bring this technology closer to the market.

We match data on LEED- and Energy Star-certified buildings with detailed information on REIT portfolios and calculate the share of green properties for each REIT over the 2000-2011 period. We estimate a two-stage regression model and document that the greenness of REITs is positively related to three measures of operating performance - return on assets, return on equity and the ratio of funds from operations to total revenue. We also document that there is no significant relationship between the greenness of property portfolios and abnormal stock returns, suggesting that stock prices already reflect the higher cash flows deriving from investments in more efficient properties. However, REITs with a higher fraction of green properties display significantly lower market betas.

Jonkers;To reduce human causes of global warming, large scale implementation of innovative products that save energy is necessary. Innovative products first reach the early market actors who are driven by a visionary attitude. Hereafter, the products must reach the much larger mainstream market whose actors are driven by a pragmatic attitude. Many innovations, however, only appeal to the visionary early market and do not meet the more pragmatic needs of the mainstream. For that reason, innovations often fall in a "chasm" between the early market and the mainstream and fail to reach the mainstream. We developed a strategy and a protocol to aid governmental agencies in influencing the mainstream members of housing associations to adopt energy conservation innovations. Our method is an adaptation of an existing marketing method and applicable to other target groups. The first step in crossing this chasm is to find a niche segment in the mainstream as the starting point for winning the rest of the mainstream. By surveying the target group and analyzing the data, we identified 29 housing associations (234 interviewed) that belong to this niche segment. Identifying the niche segment and its determinants of behaviour is part of our 4-step protocol that leads to adapting the innovative product to meet the needs of the niche and setting up a marketing plan to win the rest of the mainstream.

The promotion of renewable energy technologies (RETs) by development partners and government organizations is one way of meeting this challenge. Despite substantial investment of effort, the diffusion of RETs in Africa has been disappointing, leading to a search for more effective policies and approaches. In this paper, we discuss the role of technological innovation system (TIS) in fostering technology diffusion. We argue that the functional build up of TIS shapes technology diffusion levels in least-developed country settings. We report a comparative analysis of the biogas TIS in Kenya and Rwanda by applying the so-called the 'functions approach to innovation systems'. On this preliminary evidence, we argue that patterns of accumulation of TIS functions may determine rates of technology diffusion. We argue that to ensure accelerated diffusion of RETs, policy attention should be paid to improving the functional performance of TIS.

Our analysis is inspired by the philosophy of Herman Dooyeweerd, in particular his transcendental criticism and theory of modalities. We describe how Pearce and Turner theorize the concept of sustainable development. On the basis of this description we identify immanent tensions in their approach and analyze to what extent these tensions are caused by implicit normative presuppositions in the key concepts used by Pearce and Turner. Finally, we examine whether Dooyeweerd’s conception of the economic aspect can diminish these tensions.

The Technological Innovation Systems (TIS) framework presents a list of system functions for the analysis of the development of a technology. It has often been applied to renewable energy technologies, but with a strong focus on advanced economies. In this paper, we elaborate on emerging economy innovation system formation, structured according to TIS functions. Rather than analysing development of the technology, we analyse the development of the Chinese TIS vis-a-vis the global forefront. Key to this notion is that TIS, especially for clean-tech, are transnational phenomena. Lagging TIS depend on the global TIS, whereas leading TIS contribute to its formation. It is concluded that China has reduced its dependence on foreign knowledge and investment, but the outward contribution remains limited. The main challenge to foreign market expansion lies in reforming the domestic TIS to focus on turbine quality rather than cost reduction. Demonstration projects are needed, especially for large capacity and offshore turbine models, in order to build up operational history and get quality certification.

It is well known that a unilateral CO2 abatement policy in one region may cause CO2 emissions to increase in non-abating regions because of the relocation of CO2-intensive firms and because of energy market effects. If, however, the CO2 mitigation policy induces energy-saving technological innovation in the home region and this innovation can freely spill-over to energy users abroad, carbon leakage may be offset by induced efficiency gains in foreign firms. In this paper we develop a simple mathematical model of carbon leakage and technological spillovers and perform numerical simulations with an adjusted CGE model to illustrate the potential importance of international technology spillovers. We show that carbon leakage can become negative at moderate levels of technology spillover.

Crescenzi; Aijie Wang; Raffaele Liberatore; Cristiano Varrone; Cristiano Varrone;Abstract The worldwide energy demand has been continuously increasing, thus requesting more sustainable alternatives to the rapidly depleting fossil fuels. Therefore, biofuels such as hydrogen, bioethanol and biodiesel are gaining more importance as a renewable and pollution-free solution, which might give a significant contribution to the future energy mix. In recent years, the exponential growth of biodiesel production has led to a glycerol glut, however, according to some authors, crude glycerol might represent a suitable, abundant and low-priced feedstock for fermentation technologies. In this study we performed an energetic and economic assessment of an innovative process, which is under development in our lab, for the bioconversion of crude glycerol into ethanol and hydrogen. Ongoing experiments showed the possibility to reach at least 26 g/L of ethanol, together with 9 L of hydrogen, in non-sterile conditions and without nutrient supplements. Since kinetics and ethanol concentration need to be further improved, we performed this study with a view to evaluate the possibility of reaching economic viability. Results showed that with 26 g/L of ethanol and a retention time as high as 120 h, the calculated energy cost would be about 0.019 €/kW hth and 0.057 €/kW hel, considering the contribution of both, hydrogen and bioethanol. Moreover, bioethanol cost would be as low as 0.21 €/L, even without taking into account the possible hydrogen revenues. These results are very promising and suggest that the process has reasonable chances to achieve economic viability, thus deserving further attention. The procedure followed in this work provided a realistic and concrete target to pursue in the future lab experiments, in order to bring this technology closer to the market.

We match data on LEED- and Energy Star-certified buildings with detailed information on REIT portfolios and calculate the share of green properties for each REIT over the 2000-2011 period. We estimate a two-stage regression model and document that the greenness of REITs is positively related to three measures of operating performance - return on assets, return on equity and the ratio of funds from operations to total revenue. We also document that there is no significant relationship between the greenness of property portfolios and abnormal stock returns, suggesting that stock prices already reflect the higher cash flows deriving from investments in more efficient properties. However, REITs with a higher fraction of green properties display significantly lower market betas.

Jonkers;To reduce human causes of global warming, large scale implementation of innovative products that save energy is necessary. Innovative products first reach the early market actors who are driven by a visionary attitude. Hereafter, the products must reach the much larger mainstream market whose actors are driven by a pragmatic attitude. Many innovations, however, only appeal to the visionary early market and do not meet the more pragmatic needs of the mainstream. For that reason, innovations often fall in a "chasm" between the early market and the mainstream and fail to reach the mainstream. We developed a strategy and a protocol to aid governmental agencies in influencing the mainstream members of housing associations to adopt energy conservation innovations. Our method is an adaptation of an existing marketing method and applicable to other target groups. The first step in crossing this chasm is to find a niche segment in the mainstream as the starting point for winning the rest of the mainstream. By surveying the target group and analyzing the data, we identified 29 housing associations (234 interviewed) that belong to this niche segment. Identifying the niche segment and its determinants of behaviour is part of our 4-step protocol that leads to adapting the innovative product to meet the needs of the niche and setting up a marketing plan to win the rest of the mainstream.

The promotion of renewable energy technologies (RETs) by development partners and government organizations is one way of meeting this challenge. Despite substantial investment of effort, the diffusion of RETs in Africa has been disappointing, leading to a search for more effective policies and approaches. In this paper, we discuss the role of technological innovation system (TIS) in fostering technology diffusion. We argue that the functional build up of TIS shapes technology diffusion levels in least-developed country settings. We report a comparative analysis of the biogas TIS in Kenya and Rwanda by applying the so-called the 'functions approach to innovation systems'. On this preliminary evidence, we argue that patterns of accumulation of TIS functions may determine rates of technology diffusion. We argue that to ensure accelerated diffusion of RETs, policy attention should be paid to improving the functional performance of TIS.

Our analysis is inspired by the philosophy of Herman Dooyeweerd, in particular his transcendental criticism and theory of modalities. We describe how Pearce and Turner theorize the concept of sustainable development. On the basis of this description we identify immanent tensions in their approach and analyze to what extent these tensions are caused by implicit normative presuppositions in the key concepts used by Pearce and Turner. Finally, we examine whether Dooyeweerd’s conception of the economic aspect can diminish these tensions.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2013 DenmarkPublisher:Elsevier BV Authors: Gosens, Jorrit; Lu, Yonglong;There is increasing attention for the contribution of emerging economies to global innovation, including innovation of renewable energy technologies. The Technological Innovation Systems (TIS) framework presents a list of system functions for the analysis of the development of a technology. It has often been applied to renewable energy technologies, but with a strong focus on advanced economies. In this paper, we elaborate on emerging economy innovation system formation, structured according to TIS functions. Rather than analysing development of the technology, we analyse the development of the Chinese TIS vis-a-vis the global forefront. Key to this notion is that TIS, especially for clean-tech, are transnational phenomena. Lagging TIS depend on the global TIS, whereas leading TIS contribute to its formation. It is concluded that China has reduced its dependence on foreign knowledge and investment, but the outward contribution remains limited. The main challenge to foreign market expansion lies in reforming the domestic TIS to focus on turbine quality rather than cost reduction. Demonstration projects are needed, especially for large capacity and offshore turbine models, in order to build up operational history and get quality certification.
