Paragraphs

Our Report draws attention to a complex but understudied issue: How will climate warming alter losses of major food crops to insect pests? Because empirical evidence on plant-insect-climate interactions is scarce and geographically localized, we developed a physiologically based model that incorporates strong and well-established effects of temperature on metabolic rates and on population growth rates. We acknowledged that other factors are involved, but the ones we analyzed are general, robust, and global (13).

Parmesan and colleagues argue that our model is overly simplistic and that any general model is premature. They are concerned that our model does not incorporate admittedly idiosyncratic and geographically localized aspects of plant-insect interactions. Some local effects, such as evidence that warmer winters will harm some insects but not others, were in fact evaluated in our sensitivity analyses and shown to be minor (see the Report's Supplementary Materials). Other phenomena, such as plant defenses that benefit some insects and threaten others, are relevant but are neither global nor directional. Furthermore, because Parmesan et al. present no evidence that such idiosyncratic and localized interactions will outweigh the cardinal and universally strong impacts of temperature on populations and on metabolic rates (13), their conclusion is subjective.

We agree with Parmesan and colleagues that the question of future crop losses is important and needs further study, that targeted experimental data are needed (as we wrote in our Report), and that our estimates are likely to be conservative (as we concluded, but for reasons different from theirs). However, we strongly disagree with their recommendation to give research priority to gathering localized experimental data. That strategy will only induce a substantial time lag before future crop losses can be addressed.

We draw a lesson from models projecting future climates. Those models lack the “complexity and idiosyncratic nature” of many climate processes, but by building from a few robust principles, they successfully capture the essence of climate patterns and trends (4). Similarly, we hold that the most expeditious and effective way to anticipate crop losses is to develop well-evidenced ecological models and use them to help guide targeted experimental approaches, which can subsequently guide revised ecological models. Experiments and models should be complementary, not sequential.

Paragraphs

Reconciling higher freshwater demands with finite freshwater resources remains one of the great policy dilemmas. Given that crop irrigation constitutes 70% of global water extractions, which contributes up to 40% of globally available calories (1), governments often support increases in irrigation efficiency (IE), promoting advanced technologies to improve the “crop per drop.” This provides private benefits to irrigators and is justified, in part, on the premise that increases in IE “save” water for reallocation to other sectors, including cities and the environment. Yet substantial scientific evidence (2) has long shown that increased IE rarely delivers the presumed public-good benefits of increased water availability. Decision-makers typically have not known or understood the importance of basin-scale water accounting or of the behavioral responses of irrigators to subsidies to increase IE. We show that to mitigate global water scarcity, increases in IE must be accompanied by robust water accounting and measurements, a cap on extractions, an assessment of uncertainties, the valuation of trade-offs, and a better understanding of the incentives and behavior of irrigators.

Paragraphs
Handbook of International Food and Agricultural Policies is a three-volume set that aims to provide an accessible reference for those interested in the aims and implementation of food and farm policies throughout the world. The treatment is authoritative, comprehensive and forward looking. The three volumes combine scholarship and pragmatism, relating academic writing to real-world issues faced by policy-makers. A companion volume looking at the future resource and climate challenges for global agriculture will be published in the future.

Volume I covers Farm and Rural Development policies of developed and developing countries. The volume contains 20 country chapters together with a concluding comprehensive synthesis of lessons to be drawn from the experiences of the individual countries.

Volume II examines the experience of countries with food policies, including those dealing with food safety and quality and the responsibility for food security in developing countries. The chapters address issues such as obesity, nutritional supplements, organic foods, food assistance programs, biotech food acceptance, and the place of private standards.

Volume III describes and explains the international trade dimension of farm and food policies — both at the bilateral and regional level — and also the multilateral rules that influence and constrain individual governments. The volume also looks at the steps that countries are together taking to meet the needs of developing and low-income countries.

The volumes are of value to students and researchers interested in economic development, agricultural markets and food systems. Policy-makers and professionals involved in monitoring and regulating agricultural and food markets would also find the volumes useful in their practical work. This three-volume set is also a suitable source for the general public interested in how their food system is influenced by government policies.

Readership: Students and researchers who are interested in economic development, agricultural markets and food systems; and policy-makers and professionals involved in monitoring and regulating agricultural and food markets.

The emergence of a global digital ecosystem has been a boon for global communication and the democratization of the means of distributing information. The internet, and the social media platforms and web applications running on it, have been used to mobilize pro-democracy protests and give members of marginalized communities a chance to share their voices with the world. However, more recently, we have also seen this technology used to spread propaganda and misinformation, interfere in election campaigns, expose individuals to harassment and abuse, and stir up confusion, animosity and sometimes violence in societies. Even seemingly innocuous digital technologies, such as ranking algorithms on entertainment websites, can have the effect of stifling diversity by failing to reliably promote content from underrepresented groups. At times, it can seem as if technologies that were intended to help people learn and communicate have been irreparably corrupted. It is easy to say that governments should step in to control this space and prevent further harms, but part of what helped the internet grow and thrive was its lack of heavy regulation, which encouraged openness and innovation. However, the absence of oversight has allowed dysfunction to spread, as malign actors manipulate digital technology for their own ends without fear of the consequences. It has also allowed unprecedented power to be concentrated in the hands of private technology companies, and these giants to act as de facto regulators with little meaningful accountability. So, who should be in charge of reversing the troubling developments in our global digital spaces? And what, if anything, can be done to let society keep reaping the benefits of these technologies, while protecting it against the risks?

The two-day forum, part of a project of the American Academy of Arts and Sciences, led by the Freeman Spogli Institute’s Karl Eikenberry and Stephen Krasner, gathered experts to examine trends in civil wars and solutions moving forward.

The Council on Foreign Relations presently tracks six countries in a state of civil war, including three (South Sudan, Afghanistan, and Yemen) where the situation is currently worsening. Furthermore, three states (Central African Republic, Myanmar, and Nigeria) are experiencing sectarian violence with the potential to become larger conflicts. With two months still remaining in 2018, the combined fatalities in Afghanistan, Syria, and Yemen alone is fast approaching 100,000 for the year.

It was against this backdrop that Shorenstein APARC’s U.S.-Asia Security Initiative (USASI), the American Academy of Arts and Sciences (AAAS), and the School for International Studies at Peking University recently co-hosted the security workshop “Civil Wars, Intrastate Violence, and International Responses.” Held in Beijing, on October 22-23, the workshop brought together thirty-five U.S. and international experts to gain a wider perspective on intrastate violence and consider the possibilities for, and limits of, intervention. The workshop is the latest activity of the AAAS project on Civil Wars, Violence, and International Responses, chaired by Ambassador Karl Eikenberry, director of USASI, and by Stephen Krasner, senior fellow at the Freeman Spogli Institute for International Studies (FSI) and professor of international relations.

“Some of the major discussion topics included the appropriate political and economic development models to apply to fragile states recovering from internal conflict, justifications for intervention, and the likely impact of great power competition on the future treatment of civil wars." - Karl Eikenberry

Workshop participants included academics and professionals with expertise in political science, global health, diplomacy, refugee field work, United Nations, and the military. Countries represented at the table included the United States, Ethiopia, France, and China. Throughout the two-day session, they examined three crucial questions: What is the scope of intrastate conflicts and civil wars, and to what extent is it attributable to domestic or international factors? What types of threats to global security emanate from state civil wars? What policy options are available to regional powers and the international community to deal with such threats?

China’s Emerging Role in Addressing Intrastate Violence

The workshop’s timing and location was prescient. Over the past two decades, China’s global exposure–through trade, investment, and financing–has increased dramatically. Coupled with a growing number of its citizens living abroad, China’s equity in other states has reached the point where it has a direct interest in those experiencing or are at risk of political instability and internal violence. Indeed, through its ambitious Belt and Road Initiative, China has the opportunity to help stabilize fragile states by stimulating economic development.

“The workshop revealed, at least for me, that China is backing away from its absolute defense of sovereignty and non-intervention,” said Stephen Krasner. “As Chinese interests have expanded around the world, and as both its investments and the number of its citizens living abroad have increased, the Chinese have become more concerned with political conditions in weakly governed countries.”

With China’s growing policy and academic interests in addressing civil wars and intrastate violence, as well as its higher international profile in places like United Nations peacekeeping operations, the Beijing event provided an excellent opportunity for Chinese experts to exchange views with their international colleagues.

Where We are Today, Where We Go Tomorrow

The Beijing workshop was arranged into four sessions, with themes focusing on trends in intrastate violence, the threats it poses to international security, the limits of intervention, and advice to policymakers.

Each panel included presentations of prepared papers, moderator comments, and an open discussion by all participants. A fifth and final session provided an opportunity to summarize the preceding discussions. The workshop then closed out with an open conversation, where participants offered insight and policy recommendations developed over the preceding two days of dialogue.

“The workshop,” observed Martha Crenshaw (shown above), a Senior Fellow at FSI, “was a unique opportunity to exchange views with Chinese colleagues on the subject of civil conflict in the contemporary world. A valuable learning experience for all of us."

The "Civil Wars, Intrastate Violence, and International Responses” workshop marks the second phase of the AAAS project by the same name that launched in 2015. The first phase of the project culminated in the publication of 28 essays across two volumes of the AAAS quarterly journal Dædalus. The ongoing second phase consists of a series of roundtables and workshops in which project participants engage with academics and with government and international organization officials to build a larger conceptual understanding of the threats posed by the collapse of state authority associated with civil wars, and to contribute to current policymaking. Project activities have included meetings with the United Nations leadership and staff; academic activities in the United States; sessions with the U.S. executive and legislative branches; and a visit to Nigeria.

Throughout the workshop, Chatham House Rule of non-attribution applied to all dialogue. A workshop report will be published by the co-hosts in early 2019.

The U.S.-Asia Security Initiative is part of Stanford University’s Walter H. Shorenstein Asia-Pacific Research Center (APARC). Led by former U.S. Ambassador and Lieutenant General (Retired) Karl Eikenberry, USASI seeks to further research, education, and policy relevant dialogues at Stanford University on contemporary Asia-Pacific security issues.

Abstract

Politicians in a number of jurisdictions with cap-and-trade markets for greenhouse gas (GHG) emissions or carbon taxes have argued that the evidence is in and the conclusion is clear: Carbon pricing doesn’t work. A number of journalists and environmental groups have jumped on the bandwagon, amplifying a misguided message.

A better understanding of how markets and price mechanisms work might change their minds — and the conversation — on the benefits of carbon pricing.
