It’s clear that the virus that causes Covid-19 travels freely. It needs no visa, having breached many points of entry. Experts at Imperial College London estimate that “in the absence of interventions, Covid-19 would have resulted in 7 billion infections and 40 million deaths globally this year.” Now is the time for governments to get ahead of the curve and respond to the emergency. It’s time to take a whole-of-government approach to strengthen testing at points of entry and institute mass testing at various points as South Korea did.

As the global climate changes, climate-related security risks are making the existing political, social, and economic challenges even more complicated. The 230 million people who live in the Horn of Africa are highly vulnerable to the impacts of climate change such as droughts and floods. Political fragility and transnational complexities make water governance a matter of regional high-level politics as well as geopolitical tensions. In short, sustainable water governance is critical for achieving resilient peace.

As we have seen over recent weeks, the impact of Covid-19 has caused unprecedented disruption, deaths, and confusion in developed countries. The public health capacity of countries such as the United States and UK has been overwhelmed. 

A special type of tree could facilitate peacebuilding in the Sahel. A stretch of semi-arid land south of the Sahara that runs from the Red Sea to the Atlantic Ocean through 10 countries (Eritrea, Sudan, Chad, Niger, Nigeria, Burkina Faso, Mali, Algeria, Mauritania, and Senegal). But the western subregion covering the Lake Chad area (the intersection of Chad, Cameroon, Nigeria, and Niger) and Liptako-Gourma (the tri-border zone of Burkina Faso, Mali, and Niger) in the Sahel has been the scene of a growing humanitarian crisis. Armed groups are terrorizing local populations. Rampant insecurity has forced 1 million people to flee their homes. People have been cut off from their livelihoods. Food insecurity is worsening. Casualties continue to mount. And climate change will likely exacerbate conditions, forcing more people to compete for depleted forest resources and land. More food shortages and instability will surely follow.

In Kenya, primary and secondary school students take courses called Life Skills Education. So do students in Malawi, Mozambique, Namibia, and Swaziland. South Sudan adds “peace-building” to the subject title. Lesotho, Madagascar, Rwanda, Tanzania, Uganda, and Zambia are more direct. These countries add the word “sexuality” to the course name.

The front lines in the battle to limit damage from the new coronavirus are expanding.

Covid-19, the disease caused by the virus, emerged in China and then blossomed in comparatively wealthy countries like Italy, South Korea, and the United States.

Now, the virus is spreading in poorer regions — in sub-Saharan Africa, South Asia, and parts of Latin America — where essential defensive measures against infectious disease are often missing.
