The Zika virus is not new, but its spread and possible connections to microcephaly—a birth defect in which a baby has an abnormally small head—have caught the international community’s attention. Zika is not the same kind of challenge as Ebola, but it will require some similar measure of international cooperation to adequately address. While the World Health Organization’s declaration of a Public Health Emergency of International Concern on Feb. 1 is a good start, there are still fundamental questions that could complicate the international community’s response. Why is Zika spreading now? The virus, which emerged out of its relative geographic […]

On Sunday, Feb. 21, Bolivians rejected a referendum that would have allowed long-serving President Evo Morales to run for a fourth term in office, continuing a recent trend across Latin America of citizens voting for change. As the country’s first president of indigenous descent in a nation where between 40 percent and 62 percent of the citizenry self-identify as indigenous, Morales remains popular but is term-limited and must leave office in 2019. The president anticipated victory. What he did not factor in, apparently, was being overtaken by Latin America’s anti-incumbency wave. Since his first election in 2006, Morales has assiduously […]

Last weekend, Bolivian voters went to the polls and did something remarkable: They told their sitting president—a popular and successful one—that they will not allow him to remain in power for as long as he wishes. The voters’ rejection of a constitutional amendment that would have allowed President Evo Morales to run for a fourth consecutive term came as a painfully unexpected blow to a politician grown accustomed to landslide victories and popular adulation. The vote sent shockwaves across Bolivia. More importantly, it sent an important message to other politicians with autocratic tendencies in the region: Latin American democracy is […]

A sign that reads in Spanish "fight to return Cristina's leadership" during a protest against President Mauricio Macri's economic measures, Buenos Aires, Argentina, Dec. 17, 2015 (AP photo by Victor R. Caivano).

When Argentina’s president, Mauricio Macri, presented a serious proposal to foreign bondholders last week, he took one more step along a path that leads away from the country’s dozen years of leftist populism at the hands of former President Cristina Fernandez de Kirchner and her predecessor and late husband, Nestor Kirchner. In fact, Macri’s offer to creditors, whatever its ultimate fate, represents a blow to the very structure of Kirchnerismo, whose economic and foreign policies he is dismantling with breathtaking speed. Macri’s election in 2015, as is now evident, follows a global trend of dissatisfaction that favors candidates from outside […]

A public health emergency is, above all, a human crisis. But its consequences don’t end there. A major emergency, whether its severity is real or perceived, can have a significant economic and political impact. Now that the World Health Organization has declared the Zika virus an “international public health emergency,” warning that the mosquito-borne pathogen is spreading “explosively,” the Zika outbreak has become loaded with even more political power. Zika’s force comes not only from the tragic effects it can apparently have on babies. Scientists have not proven the link, but they believe the virus is behind the thousands of […]

The global weather event known as El Niño has been blamed for droughts in Central America and northern South America and record-breaking floods in Argentina, Brazil and Paraguay. But some scientists warn that the worst could be yet to come. El Niño poses major challenges for Latin America’s governments, some of which are in the midst of economic and political crises. The weather phenomenon is also testing their ability to face the growing threat of climate change, now and in the future. Scientists believe that El Niño, a warming of the central and eastern Pacific Ocean about once every decade […]
