Última Valuation of Linkages between Climate Change, Biodiversity and Productivity of European Agro-Ecosystems AgEcon Palatnik, Ruslana Rachel; Nunes, Paulo A.L.D.. It is clear that climate change involves changes in temperature and precipitation and therefore directly affects land productivity. However, this is not the only channel for climatic change to affect agro-systems. Biodiversity is subject to climatic fluctuations and in turn may alter land productivity too. Firstly, biodiversity is an input into agro-ecosystems. Secondly, biodiversity supports the functioning of these systems (e.g. the balancing of the nutrient cycle). Thirdly, agro-systems also host important wildlife species which, though not always, play a functional role in land productivity, nonetheless constitute important sources of landscape amenities. The present paper illustrates a unique attempt to economically assess this additional effect...

Ano: 2012 URL: http://purl.umn.edu/120467 Equity Weighting and the Marginal Damage Costs of Climate Change AgEcon Anthoff, David; Hepburn, Cameron; Tol, Richard S.J.. Climate change would impact different countries differently, and different countries have different levels of development. Equity-weighted estimates of the (marginal) impact of greenhouse gas emissions reflect these differences. Equity-weighted estimates of the marginal damage cost of carbon dioxide emissions are substantially higher than estimates without equity-weights; equity-weights may also change the sign of the social cost estimates. Equity weights need to be normalised. Our estimates differ by two orders of magnitude depending on the region of normalisation. A discounting error of equity weighted social cost of carbon estimates in earlier work (Tol, Energy Journal, 1999), led to an error of a factor two. Equity-weighted estimates are sensitive to...

Ano: 2007 URL: http://purl.umn.edu/9325 The Optimal Climate Policy Portfolio when Knowledge Spills Across Sectors AgEcon Massetti, Emanuele; Nicita, Lea. This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy sector, we show that the combination between environmental and knowledge externalities provides a strong rationale for implementing a portfolio of policies for both emissions reduction and the internalisation of knowledge externalities. Moreover, we show that implementing technology policy as a substitute for stabilisation policy is likely to increase global emissions.

Ano: 2010 URL: http://purl.umn.edu/92912 The Effect of Climate Change, CO2 Fertilization, and Crop Production Technology on Crop Yields and Its Economic Implications on Market Outcomes and Welfare Distribution AgEcon Attavanich, Witsanu; McCarl, Bruce A.. Many studies have done econometric estimates of how climate alters crop yields and or land rents in an effort to gain information on potential effects of climate change. However, an important related factor, the atmospheric carbon dioxide (CO2) concentration, and in fact a driver of climate change is ignored. This means the prior econometric estimates are biased as they infer what will happen under climate change from observations in the recent past, but without consideration of CO2 effects. Furthermore although CO2 has been varying, it has proceeded at a very linear pace and cannot be disentangled from technological progress using historical crop yield data. This paper is designed to overcome this issue and estimate the consequences that CO2 has and...

Ano: 2011 URL: http://purl.umn.edu/103324 Risk Belief, Producer Demand, and Valuation of Improved Irrigations: Results from Field Experiments in Mt. Kilimanjaro AgEcon Muamba, Francis; Kraybill, David S.. This paper systematically estimates the potential benefit of introducing improved irrigation schemes in Mt. Kilimanjaro to help rain dependent farmers cope with the risks of climate change. The study uses Contingent Valuation Method (CVM) to elicit farmers’ Willingness to Pay (WTP) for eliminating the risks of crop loss by accessing improved irrigation schemes. Data for the analysis were gathered using a double bounded survey from over 200 randomly-sampled farmers in 15 villages. The study makes a contribution to the applied welfare literature and should also be useful for policymakers in Africa. The policy contribution consists of valuation of improved irrigation in the presence of climate change risks. The applied welfare contribution consists of...

Ano: 2010 URL: http://purl.umn.edu/61653 REDD in the Carbon Market: A General Equilibrium Analysis AgEcon Bosello, Francesco; Eboli, Fabio; Parrado, Ramiro; Rosa, Renato. Deforestation is a major source of CO2 emissions, accounting for around 17% of total annual anthropogenic carbon release. While the cost estimates of reducing deforestation rates vary considerably depending on model assumptions, it is widely accepted that emissions reductions from avoided deforestation consist of a relatively low cost mitigation option. Halting deforestation is therefore not only a major ecological challenge, but also a great opportunity to cost effectively reduce climate change negative impacts. In this paper we analyze the impact of introducing avoided deforestation credits into the European carbon market using a multiregional Computable General Equilibrium model – the ICES model (Inter-temporal Computable Equilibrium System).

Ano: 2010 URL: http://purl.umn.edu/98100 An analysis of the determinants of flood damages AgEcon Ferreira, Susana. In this paper we analyze mortality caused by 2,194 large flood events between 1985 and 2008 in 108 countries. Unlike previous studies that looked at natural-disaster mortality, we find that year-to-year changes in income and institutional determinants of vulnerability do not affect flood mortality directly. Income and institutions influence mortality only indirectly, through their impact on the intensity and frequency of floods. Population exposure affects the number of deaths both directly and indirectly. Higher population exposure results in more deaths once the flood has occurred, but it is associated with smaller floods. In developing countries it also reduces the count of floods.

Ano: 2010 URL: http://purl.umn.edu/98381 Modeling Linkages Between Climate Policy and Land Use: An Overview AgEcon van der Werf, Edwin; Peterson, Sonja. Agriculture and forestry play an important role in emitting and storing greenhouse gases. For an efficient and cost-effective climate policy it is therefore important to explicitly include land use, land use change, and forestry (LULUCF) in economy-climate models. This paper gives an overview and assessment of existing approaches to include land use, land-use change, and forestry into climate-economy models or to link economy-climate models to land-use models.

Ano: 2007 URL: http://purl.umn.edu/9545 Climate Change Assessment and Agriculture in General Equilibrium Models: Alternative Modeling Strategies AgEcon Palatnik, Ruslana Rachel; Roson, Roberto. Agricultural sectors play a key role in the economics of climate change. Land as an input to agricultural production is one of the most important links between economy and the biosphere, representing a direct projection of human action on the natural environment. Agricultural management practices and cropping patterns have a vast effect on biogeochemical cycles, freshwater availability and soil quality. Agriculture also plays an important role in emitting and storing greenhouse gases. Thus, to consistently investigate climate policy and future pathways for the economic and natural environment, a realistic representation of agricultural land-use is essential. Computable General Equilibrium (CGE) models have increasingly been used to this purpose. CGE models...

Ano: 2009 URL: http://purl.umn.edu/54284 Estimating Ricardian Models With Panel Data AgEcon Massetti, Emanuele; Mendelsohn, Robert. Many nonmarket valuation models, such as the Ricardian model, have been estimated using cross sectional methods with a single year of data. Although multiple years of data should increase the robustness of such methods, repeated cross sections suggest the results are not stable. We argue that repeated cross sections do not properly specify the model. Panel methods that correctly specify the Ricardian model are stable over time. The results suggest that many cross sectional methods including hedonic studies and travel cost studies could be enhanced using panel data.

Ano: 2011 URL: http://purl.umn.edu/115727 Carbon Dioxide Capture and Storage (CCS) - Liability for Non-Permanence under the UNFCCC AgEcon Bode, Sven; Jung, Martina. Prior to CoP 10, our discussion paper "On the Integration of Carbon Capture and Storage into the International Climate Regime" argued that carbon capture and storage (CCS) was similar to carbon sequestration in the area of Land Use, Land-Use Change and Forestry (LULUCF). This was criticized by several readers who observed that treating CCS as a removal activity (sink) would not be compatible with the UNFCCC sink definition, what we already had mentioned in the paper. The present paper is based on the UNFCCC definition and analyses how CCS could be integrated into the climate regime. As CO2 may re-enter the atmosphere after injection into geological reservoirs, the question of long-term liability has to be considered. Apart from this aspect, additional...

Ano: 2005 URL: http://purl.umn.edu/26131 What Drives the International Transfer of Climate Change Mitigation Technologies? Empirical Evidence from Patent Data AgEcon Dechezlepretre, Antoine; Glachant, Matthieu; Meniere, Yann. Using patent data from 66 countries for the period 1990–2003, we characterize the factors which promote or hinder the international diffusion of climate-friendly technologies on a global scale. Regression results show that technology-specific capabilities of the recipient countries are determinant factors. In contrast, the general level of education is less important. We also show that restrictions to international trade—e.g., high tariff rates—and lax intellectual property regimes negatively influence the international diffusion of patented knowledge. A counter-intuitive result is that barriers to foreign direct investments can promote transfers. We discuss different possible interpretations.

Ano: 2010 URL: http://purl.umn.edu/59416 Invention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data AgEcon Dechezlepretre, Antoine; Glachant, Matthieu; Hascic, Ivan; Johnstone, Nick; Meniere, Yann. Accelerating the development of less GHG intensive technologies and promoting their global diffusion - in particular in fast-growing emerging economies - is imperative in achieving the transition to a low-carbon economy. Consequently, technology is at the core of current discussions about the post-Kyoto regime. The purpose of this study is to fuel this discussion by providing an in-depth analysis of the geographic distribution of climate mitigation inventions since 1978 and their international diffusion on a global scale. We use the EPO/OECD World Patent Statistical Database (PATSTAT) which includes patents from 81 national and international patent offices. Note that the Least Developed Countries patent a negligible number of inventions, meaning that the...

Ano: 2011 URL: http://purl.umn.edu/100537 The Economics of Geological CO2 Storage and Leakage AgEcon van der Zwaan, Bob; Gerlagh, Reyer. The economics of CO2 capture and storage in relation to the possibility of significant leakage of CO2 from geological reservoirs once this greenhouse gas has been stored artificially underground will be among the main determinants of whether CCS can significantly contribute to a deep cut in global CO2 emissions. This paper presents an analysis of the economic and climatic implications of the large-scale use of CCS for reaching a stringent climate change control target, when geological CO2 leakage is accounted for. The natural scientific uncertainties regarding the rates of possible leakage of CO2 from geological reservoirs are likely to remain large for a long time to come.

Ano: 2008 URL: http://purl.umn.edu/6372 How to Measure Carbon Equity: Carbon Gini Index Based on Historical Cumulative Emission Per Capita AgEcon Fei, Teng; Jiankun, He; Xunzhang, Pan; Chi, Zhang. This paper uses Lorenz Curve and Gini Index with adjustment to per capita historical cumulative emission and constructs Carbon Gini Index to measure inequality in climate change area. The analysis using Carbon Gini Index shows that 70% of carbon space in the atmosphere has been used for unequal distribution, which is almost the same as that of income in the country with the biggest gap between rich and poor in the world. The carbon equity should be an urgency and priority in the climate agenda. Carbon Gini Index established in this paper can be used to measure inequality in the distribution of carbon space and provide a quantified indicator for measurement of carbon equity among different proposals.

In this paper we use the hybrid integrated model WITCH to quantify and analyze the investments and financial flows stimulated by a climate policy to stabilize Greenhouse Gases concentrations at 550ppm CO2-eq at the end of the century. We focus on investments to decarbonize the power sector and on investments in knowledge creation. We examine the financial flows associated with the carbon market and the implications for the international trade of oil. Criticalities in investment requirements will emerge when coal power plants with carbon capture and sequestration and nuclear power plants are deployed around 2020-2040, both in high and low income regions.

China’s emerging standing in the world demands a major rethinking of its diplomatic strategies. Given its population size, geographical scale, economic power and military presence, China is poised to play a larger political role in the twenty-first century, and is thus perceived by the international community to have greater capacities, capabilities and responsibilities. At the same time, environmental stresses caused by China’s energy and resources demands have become increasingly evident in recent years, urging China to cultivate delicate diplomatic relations with its neighbors and strategic partners.

We present a computable general equilibrium model properly modified to analyse the potential role of the European forestry sector within climate mitigation. Improvements on database and modelling frameworks allow accounting for land heterogeneity across and within regions and for land transfers between agriculture, grazing, and forestry. The forestry sector has been modified to track carbon mitigation potential from both intensive and extensive forest margins, which have been calibrated according to a forest sectoral model. Two sets of climate policies are simulated. In a first scenario, Europe is assumed to commit unilaterally to reduce CO2 emissions by 20% and 30%, by 2020. In a second scenario, in addition to the emissions quotas, progressively higher...
