On December 1, 2009 the Treaty of Lisbon entered into force, bringing to an end eight years of discussions on treaty reforms in the European Union (EU). It included many of the institutional reforms that were originally part of the proposed EU Constitution, voted down by voters in France and the Netherlands in 2005. The Treaty of Lisbon could potentially be one of the most important EU treaties, depending on whether, for example, the newly created permanent European Council Presidency will manage to assert its authority and whether the Parliament will succeed at imposing its interpretation of the treaties. The objectives of this seminar are twofold. First, it will present an overview of the most important political and institutional reforms of the Treaty of Lisbon, and discuss its implications. Second, it will focus on EU trade policy and study how the Treaty of Lisbon will affect it. Trade policy is a good policy area to analyze, because it is one of the areas in which the EU’s powers are most extensive, and because the Parliament acquired new powers in this area, as it did in many other policy domains. Procedurally trade policy differs significantly from other EU policies: the Commission negotiates trade agreements based on mandates it receives from the Council. Agreements need final approval from the Council and, since December, the Parliament. The seminar will present a political-economic analysis of EU trade policy, analyze the role of the mandate, and study the implications of the increased role of the Parliament.  

Christophe Crombez is a specialist of European Union (EU) politics and business-government relations in Europe. His research focuses on EU institutions, the institutions' impact on EU policies under alternative procedural arrangements, EU institutional reform, lobbying in the EU, and electoral laws and their consequences for voter representation, party politics and government formation.

Crombez has been at the Forum on Contemporary Europe (FCE) at the Freeman Spogli Institute for International Studies at Stanford University as a visiting professor since 1999. At FCE he organizes seminars and other events on European Union politics and economics and European political systems. Crombez is also visiting professor at Stanford's Graduate School of Business, where he teaches a course on Politics and Business in Europe. He also teaches in the International Relations Program.

Furthermore, Crombez is professor of political economy and strategy at the University of Leuven in Belgium. He has been teaching in Leuven's business and economics department since 1994. His teaching responsibilities include political business strategy and applied game theory.

Christophe Crombez obtained a B.A. (Licentiaat) in Applied Economics from the University of Leuven in 1989, and a Ph.D. in Business, Political Economics, from Stanford University in 1994.

 

Audio Synopsis:

Professor Crombez first highlights key characteristics of the EU treaty system: each iteration of the treaty increases European integration; the growth of majority voting promotes smoother decision making; and every new treaty requires compromise between member states, and between political factions within the EU. Crombez then outlines changes in the Lisbon Treaty, including new policy areas for cooperation such as climate change, space policy, sports, judicial and police cooperation, and homeland security. The treaty establishes the European External Action Service, a kind of European diplomatic corps. Majority voting has been implemented in 68 new policy areas, including transport policy, immigration policy, and social security for migrant workers. The treaty grants significant new power to Parliament in multiple policy areas, and creates a permanent EU presidency. Progress has not been smooth, however: the Lisbon Treaty was voted down by Ireland in 2008 (before later being ratified), and much progress on actual policy is slowed by the reluctance of member state representatives to vote against the views of their constituents. Areas for optimism, Crombez explains, include two clauses that enable progress without a change to the treaty:

1.     Passerelle Clause: 8 articles outlining new policy areas previously requiring unanimous decisions which can now be decided through majority voting, except on defense-related issues.

2.     Flexibility Clause: decisions can now be made on issues where the EU lacks explicit authority if those issues promote the goals of the treaty. Unanimity is required, but not a formal change of the treaty.

Professor Crombez then turns his focus to trade policy under the Lisbon Treaty. An important change is that Parliament now has the option of codecision, in addition to the existing procedure of consultation (where the Council approves the Commission's proposal by unanimous decision). Codecision, in contrast, allows for qualified majority voting - leading the Commission to propose policies it may not think are ideal but which will more likely pass. In this way, Crombez feels codecision has made EU trade policy resemble US trade policy, wherein the executive branch may desire more liberal policies than what the legislature will accept. Crombez predicts this system may "lower the bar" and lead to more protectionist trade policies.

Berkeley and Stanford - Climate change could increase the likelihood of civil war in sub-Saharan Africa by over 50 percent within the next two decades, according to a new study led by a team of researchers at University of California, Berkeley, Stanford University, New York University and Harvard University, and published in today's (Monday, Nov. 23) online issue of the journal Proceedings of the National Academy of Sciences (PNAS).

The study provides the first quantitative evidence linking climate change and the risk of civil conflict. It concludes by urging accelerated support by African governments and foreign aid donors for new and/or expanded policies to assist with African adaptation to climate change.

"Despite recent high-level statements suggesting that climate change could worsen the risk of civil conflict, until now we had little quantitative evidence linking the two," said Marshall Burke, the study's lead author,  a graduate student at UC Berkeley's Department of Agricultural and Resource Economics, and research associate at the Program on Food Security and the Environment. "Unfortunately, our study finds that climate change could increase the risk of African civil war by over 50 percent in 2030 relative to 1990, with huge potential costs to human livelihoods."

"We were definitely surprised that the linkages between temperature and recent conflict were so strong," said Edward Miguel, professor of economics at UC Berkeley and faculty director of UC Berkeley's Center for Evaluation for Global Action. "But the result makes sense. The large majority of the poor in most African countries depend on agriculture for their livelihoods, and their crops are quite sensitive to small changes in temperature.  So when temperatures rise, the livelihoods of many in Africa suffer greatly, and the disadvantaged become more likely to take up arms."

Understanding the causes and consequences of civil strife in much of the African continent has been a major focus of the social sciences for decades, said Miguel, given the monumental suffering has resulted from it.

In the study, the researchers first combined historical data on civil wars in sub-Saharan Africa with rainfall and temperature records across the continent. They found that between 1980 and 2002, civil wars were significantly more likely in warmer-than-average years, with a 1 degree Celsius increase in temperature in a given year raising the incidence of conflict across the continent by nearly 50 percent.

Building on this historical relationship between temperature and conflict, the researchers then used projections of future temperature and precipitation change to quantify future changes in the likelihood of African civil war. Based on climate projections from 20 global climate models, the researchers found that the incidence of African civil war could increase 55 percent by 2030, resulting in an additional 390,000 battle deaths if future wars are as deadly as recent wars.

All climate models project rising temperatures in coming decades, said David Lobell, study co-author and an assistant professor of environmental earth system science at Stanford and center fellow at Stanford's Program on Food Security and the Environment, a joint program of the Freeman Spogli Institute for International Studies and the Woods Institute for the Environment.

"On average, the models suggest that temperatures over the African continent will increase by a little over 1 degree Celsius by 2030," he added. "Given the strong historical relationship between temperature rise and conflict, this expected future rise in temperature is enough to cause big increases in the likelihood of conflict."

To confirm that this projection was not the result of large effects in just a few countries or due to overreliance on a particular climate model, the researchers recalculated future conflict projections using alternate data.  "No matter what we tried - different historical climate data, different climate model projections, different subsets of the conflict data - we still found the same basic result," said Lobell.

It's easy to think of climate change as a long way off, said the researchers, but their study shows how sensitive many human systems are to small increases in temperature, and how fast the negative impacts of climate change could be felt.

"Our findings provide strong impetus to ramp up investments in African adaptation to climate change, for instance by developing crop varieties less sensitive to extreme heat and promoting insurance plans to help protect farmers from adverse effects of the hotter climate," said Burke.

Applying findings from this study could prove useful to policy makers at the upcoming Copenhagen negotiations in December in determining both the speed and magnitude of response to climate change, the authors said.

"If the sub-Saharan climate continues to warm and little is done to help its countries better adapt to high temperatures, the human costs are likely to be staggering," said Burke.

Armed conflict within nations has had disastrous humanitarian consequences throughout much of the world. Here we undertake the first comprehensive examination of whether global climate change will exacerbate armed conflict in sub-Saharan Africa. We find strong historical linkages between civil war and temperature on the continent, with warmer years leading to significant increases in the likelihood of war. When combined with climate model projections of future temperature trends, this historical response to temperature suggests a roughly 60% increase in armed conflict incidence by 2030, or an additional 390,000 battle deaths if future wars are as deadly as recent wars.  Our results suggest an urgent need to reform African governments' and foreign aid donors' policies to deal with rising temperatures.

In a new article in the Fall 2009 issue of the Harvard International Review PESD research fellow Varun Rai discusses the critical elements of effective international carbon offsets markets. The article argues that fundamental problems of perverse incentives and huge transaction costs render the clean development mechanism (CDM) unfit as the backbone of international carbon offsets markets post-2012. Instead, the article emphasizes the need for multilateral deals around large sectors that leverage synergies between climate change benefits and the core interests of developing countries.

Violent conflicts claim 3,000 lives per day through wars, bombings and attacks that dominate the news media. Meanwhile, behind the headlines, 20,000 people die each day from causes related to hunger and poverty. Physical security and food security are deeply connected. Over a billion people suffer from chronic food insecurity, a situation that feeds violent conflict and weakens national and international security. Food insecurity is especially problematic in agricultural regions where income growth is constrained by resource scarcity, disease, and environmental stress.

Paragraphs

Recent work has shown that current bio-energy policy directives may have harmful, indirect consequences, affecting both food security and the global climate system. An additional unintended but direct effect of large-scale biofuel production is the impact on local and regional climate resulting from changes in the energy and moisture balance of the surface upon conversion to biofuel crops. Using the latest version of the WRF modeling system we conducted twenty-four, midsummer, continental-wide, sensitivity experiments by imposing realistic biophysical parameter limits appropriate for bio-energy crops in the Corn Belt of the United States. In the absence of strain/crop-specific parameterizations, a primary goal of this work was to isolate the maximum regional climate impact, for a trio of individual July months, due to land-use change resulting from bio-energy crops and to identify relative importance of each biophysical parameter in terms of its individual effect. Maximum, local changes in 2 m temperature of the order of 1C occur for the full breadth of albedo (ALB), minimum canopy resistance (RCMIN) and rooting depth (ROOT) specifications, while the regionally (105W-75W and 35N-50N) and monthly averaged response of 2 m temperature was most pronounced for the ALB and RCMIN experiments, exceeding 0.2C. The full range of the albedo variability associated with biofuel crops may be sufficient to drive regional changes in summertime rainfall. Individual parameter effects on 2 m temperature are additive, highlight the cooling contribution of higher leaf area index (LAI) and ROOT for perennial grasses (e.g., Miscanthus) versus annual crops (e.g., maize), and underscore the necessity of improving location- and vegetation-specific representation of RCMIN and ALB.
