In late October at the United Nations Economic and Social Commission for Asia and the Pacific (UN ESCAP) headquarters in Bangkok, a multi-stakeholder coalition was launched to promote the role of youth and civil society in advancing post-2015 United Nations Sustainable Development Goals (SDGs). The youth initiatives, fostering regional integration and youth service impact in the Association of Southeast Asian Nations (ASEAN) and counterpart regions of Northeast and South Asia, will be furthered through a new Asia-Pacific Peace Service Alliance. The alliance is comprised of youth leaders, foundations, civil society entities, multilateral partners and U.N. agencies. Together, their initiatives illustrate the potential of youth and multi-stakeholder coalitions to scale impacts to meet SDG development targets through youth service and social media campaigns, and partnerships with multilateral agencies, nongovernmental organizations, corporations and research institutes.

The “Asia-Pacific Forum on Youth Volunteerism to Promote Participation in Development and Peace” at UN ESCAP featured a new joint partnership of the U.S. Peace Corps and the Korea International Cooperation Agency (KOICA) as well as USAID support for the ASEAN Youth Volunteering Program. With key leadership from ASEAN youth entitles, sponsor FK Norway, Youth Corps Singapore and Peace Corps’ innovative program in Thailand, the forum also furthered President Obama’s goal of Americans serving “side by side” with other nations’ volunteers. The multi-stakeholder Asia-Pacific alliance will be powered by creative youth action and a broad array of private and public partners from Thailand, Malaysia, Myanmar, Indonesia, Singapore, the Philippines, Australia, Korea, China, Mongolia, Japan, India, Nepal, Pakistan, the U.S. and other nations.

During the event, Dr. Shamshad Akhtar, ESCAP executive secretary, pointed out that “tapping youth potential is critical to shape our shared destiny, as they are a source of new ideas, talent and inspiration. For ESCAP and the United Nations, a dynamic youth agenda is vital to ensure the success of post-2015 sustainable development.”

Dr. Surin Pitsuwan, former ASEAN secretary-general, called for a new Asia-wide multilateralism engaging youth and civil society.  In his remarks, he drew from his experience in mobilizing Asian relief and recovery efforts after Cyclone Nargis devastated the delta region of Myanmar in May 2008. Surin, honorary Alliance chairman and this year’s recipient of the Harris Wofford Global Citizenship Award, also noted the necessity of a “spiritual evolution” to a common sense of well-being to redress the “present course of possible extinction” caused by global conflicts and climate challenges. He summoned Asia-Pacific youth, representing 60 percent of the world’s young population, to “be the change you want to see” and to “commit our youth to a useful cause for humanity.”

The potential for similar upscaled service efforts in Africa, weaving regional integration and youth volunteering impact, has been assessed in Brookings research and policy recommendations being implemented in the Common Market of Eastern and Southern Africa (COMESA). Recommendations, many of which COMESA and ASEAN are undertaking, include enabling youth entrepreneurship and service contributions to livelihoods in regional economic integration schemes, and commissioning third-party support for impact evidence research.

A good example of successful voluntary service contributions from which regional economic communities like ASEAN can learn a lot is the current Omnimed pilot research intervention in Uganda. In eastern Ugandan villages, 1,200 village health workers supported by volunteer medical doctors, Uganda’s Health Ministry, Peace Corps volunteers and Global Peace Women are addressing lifesaving maternal and child health outcomes furthering UNICEF’s campaign on “integrated health” addressing malaria, diarrheal disease and indoor cooking pollution. The effort has included construction of 15 secure water sources and 1,200 clean cook stoves along with randomized controlled trials.

Last week, the young leaders from more than 40 nations produced a “Bangkok Statement” outlining their policy guidance and practical steps to guide volunteering work plans for the new Asia-Pacific alliance. Youth service initiatives undertaken in “collective impact” clusters will focus on the environment (including clean water and solar villages), health service, entrepreneurship, youth roles in disaster preparedness and positive peace. The forum was co-convened by ESCAP, UNESCO, the Global Peace Foundation and the Global Young Leaders Academy.

Volunteerism remains a powerful tool for good around the world. Young people, in particular, are motivated by the prospect of creating real and lasting change, as well as gaining valuable learning experiences that come with volunteering. This energy and optimism among youth can be harnessed and mobilized to help meet challenges facing our world today and accomplish such targets as the United Nations 2030 Sustainable Development Goals (SDGs).

On June 14, young leaders and development agents from leading non-governmental organizations (NGOs), faith-based organizations, corporations, universities, the Peace Corps, and United Nations Volunteers came together at the Brookings Institution to answer the question on how to achieve impacts on the SDGs through international service.

This was also the 10th anniversary gathering of the Building Bridges Coalition—a multi-stakeholder consortium of development volunteers— and included the announcement of a new Service Year Alliance partnership with the coalition to step up international volunteers and village-based volunteering capacity around the world.

Brookings Senior Fellow Homi Kharas, who served as the lead author supporting the high-level panel advising the U.N. secretary-general on the post-2015 development agenda, noted the imperative of engaging community volunteers to scale up effective initiatives, build political awareness, and generate “partnerships with citizens at every level” to achieve the 2030 goals.  

Kharas’ call was echoed in reports on effective grassroots initiatives, including Omnimed’s mobilization of 1,200 village health workers in Uganda’s Mukono district, a dramatic reduction of malaria through Peace Corps efforts with Senegal village volunteers, and Seed Global Health’s partnership to scale up medical doctors and nurses to address critical health professional shortages in the developing world. 

U.N. Youth Envoy Ahmad Alhendawi of Jordan energized young leaders from Atlas Corps, Global Citizen Year, America Solidaria, International Young Leaders Academy, and universities, citing U.N. Security Council Resolution 2250 on youth, peace, and security as “a turning point when it comes to the way we engage with young people globally… to recognize their role for who they are, as peacebuilders, not troublemakers… and equal partners on the ground.”

Service Year Alliance Chair General Stanley McChrystal, former Joint Special Operations commander, acclaimed, “The big idea… of a culture where the expectation [and] habit of service has provided young people an opportunity to do a year of funded, full-time service.” 

Civic Enterprises President John Bridgeland and Brookings Senior Fellow E.J. Dionne, Jr. led a panel with Seed Global Health’s Vanessa Kerry and Atlas Corps’ Scott Beale on policy ideas for the next administration, including offering Global Service Fellowships in United States Agency for International Development (USAID) programs to grow health service corps, student service year loan forgiveness, and technical support through State Department volunteer exchanges. Former Senator Harris Wofford, Building Bridge Coalition’s senior advisor and a founding Peace Corps architect, shared how the coalition’s new “service quantum leap” furthers the original idea announced by President John F. Kennedy, which called for the Peace Corps and the mobilization of one million global volunteers through NGOs, faith-based groups, and universities.

The multi-stakeholder volunteering model was showcased by Richard Dictus, executive coordinator of U.N. Volunteers; Peace Corps Director Carrie Hessler-Radelet; USAID Counselor Susan Reischle; and Diane Melley, IBM vice president for Global Citizenship. Melley highlighted IBM’s 280,000 skills-based employee volunteers who are building community capacity in 130 countries along with Impact 2030—a consortium of 60 companies collaborating with the U.N.—that is “integrating service into overall citizenship activities” while furthering the SDGs.

The faith and millennial leaders who contributed to the coalition’s action plan included Jim Lindsay of Catholic Volunteer Network; Service Year’s Yasmeen Shaheen-McConnell; C. Eduardo Vargas of USAID’s Center for Faith-Based and Community Initiatives; and moderator David Eisner of Repair the World, a former CEO of the Corporation for National and Community Service. Jesuit Volunteer Corps President Tim Shriver, grandson of the Peace Corps’ founding director, addressed working sessions on engaging faith-based volunteers, which, according to research, account for an estimated 44 percent of nearly one million U.S. global volunteers

The key role of colleges and universities in the coalition’s action plan—including  linking service year with student learning, impact research, and gap year service—was  outlined by Dean Alan Solomont of Tisch College at Tufts University; Marlboro College President Kevin Quigley; and U.N. Volunteers researcher Ben Lough of University of Illinois Urbana-Champaign.

These panel discussion directed us towards the final goal of the event, which was a multi-stakeholder action campaign calling for ongoing collaboration and policy support to enhance the collective impact of international service in achieving the 2030 goals.

This resolution, which remains a working document, highlighted five major priorities:

1. Engage service abroad programs to more effectively address the 2030 SDGs by mobilizing 10,000 additional service year and short-term volunteers annually and partnerships that leverage local capacity and volunteers in host communities.
2. Promote a new generation of global leaders through global service fellowships promoting service and study abroad.
3. Expand cross-sectorial participation and partnerships.
4. Engage more volunteers of all ages in service abroad.
5. Study and foster best practices across international service programs, measure community impact, and ensure the highest quality of volunteer safety, well-being, and confidence.

Participants agreed that it’s through these types of efforts that volunteer service could become a common strategy throughout the world for meeting pressing challenges. Moreover, the cooperation of individuals and organizations will be vital in laying a foundation on which governments and civil society can build a more prosperous, healthy, and peaceful world.

One of global society’s foremost structural changes underway is its rapid aggregate shift from farmbased to city-based economies. More than half of humanity now lives in urban areas, and more than two-thirds of the world’s economies have a majority of their population living in urban settings. Much of the gradual movement from rural to urban areas is driven by long-term forces of economic progress. But one corresponding downside is that city-based societies become increasingly disconnected—certainly physically, and likely psychologically—from the practicalities of rural livelihoods, especially agriculture, the crucial economic sector that provides food to fuel humanity.

The nature of agriculture is especially important when considering the tantalizingly imminent prospect of eliminating extreme poverty within a generation. The majority of the world’s extremely poor people still live in rural areas, where farming is likely to play a central role in boosting average incomes. Agriculture is similarly important when considering environmental challenges like protecting biodiversity and tackling climate change. For example, agriculture and shifts in land use are responsible for roughly a quarter of greenhouse gas emissions.

As a single word, the concept of “agriculture” encompasses a remarkably diverse set of circumstances. It can be defined very simply, as at dictionary.com, as “the science or occupation of cultivating land and rearing crops and livestock.” But underneath that definition lies a vast array of landscape ecologies and climates in which different types of plant and animal species can grow. Focusing solely on crop species, each plant grows within a particular set of respective conditions. Some plants provide food—such as grains, fruits, or vegetables—that people or livestock can consume directly for metabolic energy. Other plants provide stimulants or medication that humans consume—such as coffee or Artemisia—but have no caloric value. Still others provide physical materials—like cotton or rubber—that provide valuable inputs to physical manufacturing.

One of the primary reasons why agriculture’s diversity is so important to understand is that it defines the possibilities, and limits, for the diffusion of relevant technologies. Some crops, like wheat, grow only in temperate areas, so relevant advances in breeding or plant productivity might be relatively easy to diffuse across similar agro-ecological environments but will not naturally transfer to tropical environments, where most of the world’s poor reside. Conversely, for example, rice originates in lowland tropical areas and it has historically been relatively easy to adopt farming technologies from one rice-growing region to another. But, again, its diffusion is limited by geography and climate. Meanwhile maize can grow in both temperate and tropical areas, but its unique germinating properties render it difficult to transfer seed technologies across geographies.

Given the centrality of agriculture in many crucial global challenges, including the internationally agreed Sustainable Development Goals recently established for 2030, it is worth unpacking the topic empirically to describe what the term actually means today. This short paper does so with a focus on developing country crops, answering five basic questions: 

1. What types of crops does each country grow? 

2. Which cereals are most prominent in each country? 

3. Which non-cereal crops are most prominent in each country? 

4. How common are “cash crops” in each country? 

5. How has area harvested been changing recently? 

Readers should note that the following assessments of crop prominence are measured by area harvested, and therefore do not capture each crop’s underlying level of productivity or overarching importance within an economy. For example, a local cereal crop might be worth only $200 per ton of output in a country, but average yields might vary across a spectrum from around 1 to 6 tons per hectare (or even higher). Meanwhile, an export-oriented cash crop like coffee might be worth $2,000 per ton, with potential yields ranging from roughly half a ton to 3 or more tons per hectare. Thus the extent of area harvested forms only one of many variables required for a thorough understanding of local agricultural systems. 

The underlying analysis for this paper was originally conducted for a related book chapter on “Agriculture’s role in ending extreme poverty” (McArthur, 2015). That chapter addresses similar questions for a subset of 61 countries still estimated to be struggling with extreme poverty challenges as of 2011. Here we present data for a broader set of 140 developing countries. All tables are also available online for download.

Often the biggest challenge for older cities and close-in suburbs is not a lack of affordable housing but a need to grow, hold, and attract middle-income households and to foster mixed-income neighborhoods. This creates a policy dilemma: While federal policymakers target limited federal housing assistance to persons with the greatest needs, doing so can create concentrations of poverty within already challenged cities and suburbs. This approach also can set limits that hinder efforts to create the middle-income and mixed-income areas needed for revitalization in older communities.

With over 16 million people and nearly 8.6 million jobs, America's older industrial cities remain a vital-if undervalued-part of the economy, particularly in states where they are heavily concentrated, such as Ohio and Pennsylvania. They also have a range of other physical, economic, and cultural assets that, if fully leveraged, can serve as a platform for their renewal.

Read the Executive Summary  »

Across the country, cities today are becoming more attractive to certain segments of society. Meanwhile, economic trends-globalization, the demand for educated workers, the increasing role of universities-are providing cities with an unprecedented chance to capitalize upon their economic advantages and regain their competitive edge.

Many cities have exploited these assets to their advantage; the moment is ripe for older industrial cities to follow suit. But to do so, these cities need thoughtful and broad-based approaches to foster prosperity.

"Restoring Prosperity" aims to mobilize governors and legislative leaders, as well as local constituencies, behind an asset-oriented agenda for reinvigorating the market in the nation's older industrial cities. The report begins with identifications and descriptions of these cities-and the economic, demographic, and policy "drivers" behind their current condition-then makes a case for why the moment is ripe for advancing urban reform, and offers a five-part agenda and organizing plan to achieve it.

Is it possible to isolate the well-established mode of Arctic cooperation from the disruptive impact of the Ukraine crisis? Many stake-holders in cooperative projects with Russia keep insisting on an affirmative answer and seek to bracket out tensions emanating from such obscure locations as Debaltsevo or Mariupol. The European Union (EU), which is due to adopt a new Arctic Policy by the end of the year, would have been content to maintain the focus on environmental protection and economic development; the discussions in Brussels, however, have increasingly shifted to far less appealing “hard security” matters. Officials from the European Commission seem deeply reluctant to deal with Russia’s military activities in the high north but have to acknowledge that they are making it much more difficult to cooperate with Russia. As April’s Arctic Council ministerial meetings approach, the United States and Europe must be realistic about the ways in which far away events will negatively affect the possible achievement of their goals. 

Moscow is expanding rather than camouflaging the scope of exercises undertaken by its newly-formed Arctic Joint Strategic Command. Russian President Vladimir Putin used to proudly proclaim Russia’s abiding interest in Arctic cooperation, but even the most pro-engagement Arctic partners cannot fail to see that Russia’s interest is clearly slackening. This may be partly due to the disappearing attractiveness of exploration of the Arctic resources, since the estimated production costs of the off-shore platforms go far beyond the expected returns on the current level of oil prices. Another reason may be the disappointment in the commercial prospects of the Northern Sea Route (or Sevmorput), where maritime transit contracted by an astounding 77 percent in 2014, after several years of promising growth. A further reason may be Moscow’s recognition that the much trumpeted (and still not submitted) claim for expanding its “ownership” over the Arctic shelf cannot be legally approved because Denmark has presented its own claim, and the U.N. Commission on the Limits of the Continental Shelf cannot make any recommendations on clashing claims.

It is hard to find an active lobby in Russia for sustaining cooperative projects or at least the joint work in the Arctic Council, as many actors who promoted the Barents Cooperation in the 1990s, are either on a short leash (as is the case with regional governors) or branded as “foreign agents” (the NGOs that want to avoid such branding have to curtail or cut ties with Western colleagues). The appointment of Dmitri Rogozin as a chair of the new government commission on Arctic matters bodes ill for the cooperative endeavors because this firebrand “patriot” deservedly holds a spot on U.S., EU, and Canadian sanctions lists. 

The Russian Foreign Ministry is still circulating a message of commitment to the Arctic dialogue. The forthcoming session of the Arctic Council ministers in Iqaluit, Nunavut, Canada, might test this commitment with the issue of granting observer status to the EU. It was Canada who blocked the resolution of this issue at the previous meeting in Kiruna, Sweden, in 2013, but the controversy about seal products has been resolved, and Canada is ready to put the question on the agenda as its chairmanship of the Council expires. European Commission officials expect that during the 2015 meeting, Russia will raise objections because the EU is now seen as an antagonist, but EU officials still feel it is important to force Moscow to put their opposition on the record.

One external party that aims at enhancing and also at reformatting the Arctic cooperation is China, and while Moscow has to show eager attention to Beijing’s opinions, it cannot be comfortable with this “encroachment.” Russia’s traditional position has been that Arctic matters were the responsibility of the littoral states, but China insists on having a say and even entertains notions of the high north as a “global common,” a prospect which Moscow finds hard to swallow. 

It is indeed futile to praise the value of cooperative ties when seven members of the Arctic Council are compelled to tighten step by step the regime of sanctions against the eighth member, which is sinking into a deep economic crisis but persists in building its power projection capabilities in the High North. The usefulness of engaging Russia is beyond doubt, but it would be irresponsible to expect that joint projects in monitoring climate change could reduce the risks from expanding Russian military activities. The high north is one area where Moscow fancies itself to be in a position of power, but so far it has not found a way to enjoy it. It is not my intention to give the Kremlin war-mongers ideas about putting this military advantage to good political use, but when the likes of Rogozin or Nikolai Patrushev (secretary of the Security Council and former head of the Russian Federal Security Service) profess particular interest in the Arctic, it is only prudent to expect a brainstorm of sorts. The technique of “hybrid war” is not only the continuation but also a driver of Putin’s politics of confrontation, and this drive transforms the unique Arctic landscapes into just another “theater.”

One of global society’s foremost structural changes underway is its rapid aggregate shift from farmbased to city-based economies. More than half of humanity now lives in urban areas, and more than two-thirds of the world’s economies have a majority of their population living in urban settings.
