    Producción CientíficaToday's decision-makers rely heavily on Integrated Assessment Models to guide the decarbonisation of the energy system. Uncertainty is embedded in the assumptions these models are built upon. Unless those uncertainties are adequately assessed, using Integrated Assessment Models for policy design is unadvised. In this work we run Monte Carlo simulations with the MEDEAS model at European Union scale to assess how the uncertainties on the main drivers of the transition affect key socioeconomic and environmental indicators. In addition, One-at-a-time sensitivity exploration is performed to grade the contribution of a set of model parameters to the uncertainty in the same key indicators. The combination of the uncertainties in the model drivers magnify the uncertainty in the model outputs, which widens over time. Parameters affecting sectorial and households' energy efficiency and households' transport energy use ranked amongst the most impacting ones on simulation results.European Union's Horizon 2020 research and innovation program, grant agreement No 691287 of the Framework Program for Research and Innovation actions, H2020 LCE-21-201

    EU Dairy Quota Reform – AGMEMOD Scenario Analysis

    This study provides an in-depth model based quantitative analysis of the implications of the dairy policy reform on the milk and dairy market as well as on other agricultural markets in the EU27, EU15, EU12 and the individual MS. The objectives of the study are threefold: 1. to assess the implications of changing policy and market conditions on EU agriculture with special emphasis on milk quota phasing out and export subsidy removal by using a modelling tool; 2. to carry out policy relevant scenarios reflecting deregulation (e.g. quota abolition), changes in quota and price levels, different types and levels of direct payments; and 3. to analyse the implications of policy reform scenarios and to draw appropriate policy recommendations. Based on an overview of the existing approaches used to analyse the dairy market, the necessary adjustments to the AGMEMOD model are developed. Projections are made under a baseline of no policy change for a time horizon of 10 years for selected individual MS, the EU15 in aggregate, EU12 in aggregate (12 MS from May 2004), and the EU27 in aggregate. This baseline is contrasted with a series of scenarios which involve an increase and eventual elimination of the EU milk quota. The increase in EU milk production under the scenarios is smaller than the increase in milk quota. Milk quota rents fall to zero relatively quickly due to rising input costs and falling milk prices. However, the milk price path under the scenarios is not hugely different to that of the baseline, so it can be said that the general international market conditions in dairy and animal feed are the main drivers of the observed outcomes. In some MS, expansion potential is quite strong and in such cases production continues to expand even after quotas are removed in those scenarios which involve a larger milk quota expansion in advance of its elimination.Milk Quota, Policy Analysis, Partial Equilibrium Modelling., Agricultural and Food Policy,

    Exploiting Qualitative Information for Decision Support in Scenario Analysis

    Get PDF
    The development of scenario analysis (SA) to assist decision makers and stakeholders has been growing over the last few years through mainly exploiting qualitative information provided by experts. In this study, we present SA based on the use of qualitative data for strategy planning. We discuss the potential of SA as a decision-support tool, and provide a structured approach for the interpretation of SA data, and an empirical validation of expert evaluations that can help to measure the consistency of the analysis. An application to a specific case study is provided, with reference to the European organic farming business

    INFECTIOUS DISEASE, DEVELOPMENT, AND CLIMATE CHANGE: A SCENARIO ANALYSIS

    Get PDF
    We study the effects of development and climate change on infectious disease in Sub-Saharan Africa. Infant mortality and infectious disease are close related, but there are better data for the former. In an international cross-section, per capita income, literacy, and absolute poverty significantly affect infant mortality. We use scenarios of these three determinants, and of climate change to project the future incidence of malaria, assuming it to change proportionally to infant mortality. Malaria deaths will first increase, because of population growth and climate change, but then fall, because of development. This pattern is robust to the choice of scenario, parameters, and starting conditions; and it holds for diarrhoea, schistosomiasis, and dengue fever as well. However, the time and level of the mortality peak is very sensitive to assumptions. Climate change is important in the medium term, but dominated in the long term by development. As climate can only be changed with a substantial delay, development is the preferred strategy to reduced infectious diseases, even if that is exacerbated by climate change.Development, infectious disease, climate change, Sub-Saharan Africa, malaria

    ECONOMIC AND SOCIAL CONSEQUENCES OF BIOTECHNOLOGY: A SCENARIO ANALYSIS

    Get PDF
    Over the years agricultural technology has created remarkable commodity production growth rates and enhanced general economic growth through food production, manufactured goods and trade for most nations. Biotechnology holds the promise of continuing this remarkable record. There is a long list of potential benefits of biotechnology but unfortunately the perceived costs/risks are also many. These concerns have lead to significant consumer reluctance to accept the technology and, in some cases, outright consumer rejection of the technology. To discuss the future of biotechnology, scenario analysis is used to examine the social and economic impact of biotechnology on industrialized and emerging nations. Four scenarios are discussed in detail: biotechnology may be formally or informally banned (Scenario 1), fully accepted (Scenario 2), marketed through strict labeling (Scenario 3), or limited to non-food applications (Scenario 4). Consumer acceptance of this technology will be key to determining which scenario becomes the future for each nation. The likelihood of each scenario is different for each nation, the U.S. will most likely evolve into scenario 2 or 3, while in the EU scenarios 1 or 4 are more likely. Determining the future for emerging nations is extremely complex and dependent on several factors like malnutrition rates, environmental safety and historical trading routes. Each scenario has a major impact on small producers worldwide which ultimately influences the health of rural communities. The analysis indicates that emerging nations are the most sensitive to the timing of decisions being made about the future of biotechnology. If biotechnology becomes a reality, new data will be required to assess the social and economic impact of this technology.Research and Development/Tech Change/Emerging Technologies,
