Dynamic modelling of water demand, water availability and adaptation strategies for power plants to global change

According to the latest IPCC reports, the frequency of hot and dry periods will increase in many regions of the world in the future. For power plant operators, the increasing possibility of water shortages is an important challenge that they have to face. Shortages of electricity due to water shortages could have an influence on industries as well as on private households. Climate change impact analyses must analyse the climate effects on power plants and possible adaptation strategies for the power generation sector. Power plants have lifetimes of several decades. Their water demand changes with climate parameters in the short- and medium-term. In the long-term, the water demand will change as old units are phased out and new generating units appear in their place.In this paper, we describe the integration of functions for the calculation of the water demand of power plants into a water resources management model. Also included are both short-term reactive and long-term planned adaptation. This integration allows us to simulate the interconnection between the water demand of power plants and water resources management, i.e. water availability. Economic evaluation functions for water shortages are also integrated into the water resources management model. This coupled model enables us to analyse scenarios of socio-economic and climate change, as well as the effects of water management actions.

Climate change will affect security of individuals and populations as well as the security of states. The article reviews evidence on the scope and nature of the climate change challenge; reviews how these impacts manifest themselves in insecurity at diverse scales; and examines evidence on the political economy of adaptation responses to these impacts. I argue that climate security has been framed in public and policy debate over climate change such that climate change impacts are a threat to nation states in terms of their interests, their economies and their borders. This framing crowds out, subverts and constrains framing in terms of human-well being. I suggest that human security provides a broader and more encompassing notion of climate security than that focussed on security of states. Here, climate security focuses on the idea of freedom from harm and fear of individuals and communities and the capability to adapt to any imposed harm. From that human security perspective, the central analytical issues become those of vulnerability, adaptation and justice.     

Discursive Contestation on Technological Innovation and the Institutional Design of the UNFCCC in the New Climate Change Regime

ABSTRACT

Under the new climate change regime ushered in by the 2015 Paris Agreement, technology development and transfer have emerged as essential means of global action for climate change mitigation and adaptation. In particular, technological innovation has appeared as a leading component to be accelerated, encouraged, and enabled under the Paris Agreement. However, while making the rule book to implement the Paris Agreement, a clash has occurred between developed and developing countries over the meaning of technological innovation and the intervening policies of the United Nations Framework Convention on Climate Change (UNFCCC) to support innovation in developing countries. By exploring rule-making processes and expert-meetings under the UNFCCC, this paper examines how this discursive contestation has progressed in relation to the meaning of technological innovation and the creation of an appropriate institutional design to support developing countries’ achievement of technological innovation. The analysis is based on the theoretical framework of discursive contestation between the two discourses of de-regulatory ecological modernisation and green governmentality with right-to-development. This research concludes by positing some policy implications.     

Climate-change adaptation: The role of fiscal policy

Climate change and natural disasters have important consequences on fiscal sustainability, especially for developing countries with limited financial resources and underdeveloped institutions. The paper contributes to shed light on the role of fiscal policy in climate-change adaptation, which aims at containing the economic damage of climate change. We use an overlapping generations (OLG) model for a small open economy in which adaptation reflects the extent to which public policies reduce the negative influence of climate change on the capital depreciation rate. Adaptation includes both preventive measures, i.e. investment in infrastructure, and remedial measures, i.e. post-disaster relief and reconstruction. Through model simulations we assess the costs and benefits of both remedial and preventive actions. We find that preventive intervention leads to higher GDP growth rates than either taking no action or waiting until remedial action is necessary. However, the evidence shows that, due to high costs of early adaptation and budgetary constraints, countries tend to focus on late corrective actions, also relying on international assistance. Given the expected increase in climate-related risks, a comprehensive strategy including both preventive and corrective actions would be desirable to strengthen resilience to shocks and alleviate the financial constraints, which particularly affect small countries.

Global warming and livestock husbandry in Kenya: Impacts and adaptations

This paper examines the economic impact of climate change on livestock production in Kenya. We estimate a Ricardian model of net livestock incomes and further estimate the marginal impacts of climate change. We also simulate the impact of different climate scenarios on livestock incomes. The Ricardian results show that livestock production in Kenya is highly sensitive to climate change and that there is a non-linear relationship between climate change and livestock productivity. The estimated marginal impacts suggest modest gains from rising temperatures and losses from increased precipitation. The predictions from atmospheric ocean general circulation models suggest that livestock farmers in Kenya are likely to incur heavy losses from global warming. The highest and lowest losses are predicted from the Hadley Centre Coupled model (HADCM) and Parallel Climate Model (PCM) respectively, based on the Intergovernmental Panel on Climate Change A2 Special Report on Emissions Scenarios. The paper concludes that in the long term, climate change is likely to lead to increased poverty, vulnerability and loss of livelihoods. Several policy interventions are recommended to counter this impact.

Climate change as a threat to biodiversity: An application of the DPSIR approach

Climate change and its consequences present one of the most important threats to biodiversity and the functions of ecosystems. The stress on biodiversity is far beyond the levels imposed by the natural global climatic changes occurring in the recent evolutionary past. It includes temperature increases, shifts of climate zones, melting of snow and ice, sea level rise, droughts, floods, and other extreme weather events. Natural systems are vulnerable to such changes due to their limited adaptive capacity. Based on an analysis using the DPSIR framework, this paper discusses some of the important socio-economic driving forces of climate change, with a focus on energy use and transportation. The paper also analyses observed and potential changes of climate and the pressures they exert on biodiversity, the changes in biodiversity, the resulting impacts on ecosystem functions, and possible policy responses. The latter can be divided into mitigation and adaptation measures. Both strategies are needed, mitigation in order to stabilise the greenhouse gas concentrations in the atmosphere, and adaptation in order to adjust to changes that have already occurred or cannot be avoided. One mitigation option, increased biofuel production, which is also a response to oil depletion, would change land use patterns and increase human appropriation of net primary production of biomass, thereby threatening biodiversity. By considering the first order and second order impacts of climate change on biodiversity when developing policy measures, it will be possible to integrate ecosystem and biodiversity protection into decision-making processes.     

International support of climate change policies in developing countries: Strategic, moral and fairness aspects

International transfers in climate policy channeled from the industrialized to the developing world either support the mitigation of climate change or the adaptation to global warming. From a purely allocative point of view, transfers supporting mitigation tend to be Pareto-improving whereas this is not very likely in the case of adaptation support. We illustrate this by regarding transfer schemes currently applied under the UN Framework Convention on Climate Change (UNFCCC) and the Kyoto framework.However, if we enrich the analysis by integrating distributional aspects, we find that international adaptation funding may help both the developing and developed world. Interestingly this is not due to altruistic incentives, but due to follow-up effects on international negotiations on climate change mitigation. We argue that the lack of fairness perceived by developing countries in the international climate policy arena can be reduced by the support of adaptation in these countries. As we show - taking into account different fairness concepts - this might raise the prospects of success in international negotiations on climate change. Yet, we find that the influence of transfers may induce different fairness effects on climate change mitigation negotiations to run counter.We discuss whether current transfer schemes under the UNFCCC and the Kyoto framework adequately serve the distributive and allocative objectives pursued in international climate policy.

MONETARY VALUATION OF INSURANCE AGAINST FLOOD RISK UNDER CLIMATE CHANGE*

Climate change is projected to increase the risk of natural disasters, such as floods and storms, in certain regions. This is likely to raise the demand for natural disaster insurance. We present a stated preference survey using choice modeling with mixed logit estimation methods in order to examine the effects of climate change and the availability of government compensation on the demand for flood insurance by Dutch homeowners. Currently, no private insurance against flood damage is offered in the Netherlands. The results indicate that there are opportunities for the development of a flood insurance market.     

Governing new global health-care markets: the case of stem cell treatments

Stem cell innovation has enabled the growth of a global market of treatments for a wide range of diseases but most of this market operates outside the domain of orthodox forms of innovation governance. Much of the analysis of this issue has adopted a supply side perspective informed by the values of the orthodox scientific model of biomedical innovation, arguing that national and transnational regulation has failed to impose appropriate standards on the ‘illicit’ supply of stem cell treatments. In contrast, this paper shows how and why the analysis of global stem cell innovation governance must incorporate the market and health consumer demand into the conceptual framework. Central to the argument is the role of innovation models in mediating the relationship between demand and supply in the global market of new stem cell treatments. Different models of scientific and medical innovation mediate that relationship in different ways and, in jurisdictions where health consumer demand is frustrated, may result in parallel political demands for change in stem cell innovation governance. Such demands are likely to be resisted by the dominant scientific model, producing a further response from health consumers and a continuing dynamic in the political economy of stem cell treatments.     

Climate Change and Adaptation: The Case of Nigerian Agriculture

The present research offers an economic assessment of climate change impacts on the four major crop families characterizing Nigerian agriculture. The evaluation is performed by shocking land productivity in a computable general equilibrium model tailored to replicate Nigerian economic development up to 2050. The detail of land uses in the model has been increased by differentiating land types per agro-ecological zones. Uncertainty about future climate is captured, using, as inputs, yield changes computed by a crop model under ten general circulation models runs. Climate change turns out to be negative for Nigeria in the medium term, with production losses and increase in crop prices, higher food dependency on foreign imports, and GDP losses in all the simulations after 2025. In a second part of the paper, a cost effectiveness analysis of adaptation in Nigerian agriculture is conducted. The adaptation practices considered are a mix of cheaper “soft measures” and more costly “hard” irrigation expansion. The main result is that the cost effectiveness of the whole package depends crucially on the possibility of implementing adaptation by exploiting low-cost opportunities which show a benefit-cost ratio larger than one in all the climate regimes.

Identification of national priority areas for adaptation to climate change in China

The problem of global warming has been identified as the first in the list of the top ten environmental problems in the world. As climate change will seriously affect the social and natural world that people live in, so it may lay serious repercussions on economic progress, social improvement, and sustainable development. International bodies everywhere and many of the countries＇ governments are responding urgently to this call In recent years, climate change has affected different regions in China in different ways. In its national agenda, the Chinese government should address the problem of climate change and its negative impact on socio-economic development. In this endeavor the nation should introduce policies which will help its people and economy to adapt to these effects and changes. Priority-fields of adaptation to climate change are the sensitive areas or departments which are more vulnerable to the negative influences of climate change. The negative impacts of climate change in some parts of China are considered to be very serious indeed as they affect the whole economy and community. As a result, priority should be given to these more affected regions for the limited state financing. This paper defines adaptation and discusses the basic principles and programs in the identi.fication of national priority areas where adaptation should be exercised. Based on the past studies, four priority areas in China are identified, namely, disaster prevention and mitigation, water resources, agriculture, and ecosystem. An analysis on the identification procedures, and the reasons and tasks involved are given for each.     

Political economy of climate change, ecological destruction and uneven development

The purpose of this paper is to analyze climate change and ecological destruction through the prism of the core general principles of political economy. The paper starts with the principle of historical specificity, and the various waves of climate change through successive cooler and warmer periods on planet Earth, including the most recent climate change escalation through the open circuit associated with the treadmill of production. Then we scrutinize the principle of contradiction associated with the disembedded economy, social costs, entropy and destructive creation. The principle of uneven development is then explored through core-periphery dynamics, ecologically unequal exchange, metabolic rift and asymmetric global (in)justice. The principles of circular and cumulative causation (CCC) and uncertainty are then related to climate change dynamics through non-linear transformations, complex interaction of dominant variables, and threshold effects. Climate change and ecological destruction are impacting on most areas, especially the periphery, earlier and more intensely than previously thought likely. A political economy approach to climate change is able to enrich the analysis of ecological economics and put many critical themes in a broad context.

Multi-level Governance and Global Climate Change in East Asia

Climate change is an issue that requires integrated action at multiple levels of government and within the spheres of politics, economics, and society. National, regional, and local governments have both distinct and complementary roles in developing climate mitigation and adaptation strategies. Compared with the attention that has been given to international and national activities in East Asia, relatively limited attention has been paid to the role of urban and regional governments in combating global climate change. Cities and provinces are initiating their own climate action plans, positioning themselves as environmental model cities, and joining local, national, and international networks for climate change. This article examines urban and prefectural climate policies in China, Japan, and South Korea within a multilevel governance framework.
