The Locust in Africa and Asia, showing Spring, Summer, and Fall breeding grounds, plus migration patterns under normal conditions and as altered by climate change. Yes, the locust. Yes, that locust.
Hungry Locusts, Flying on the Winds, Eat Their Way Across Two Continents
In some years the Desert Locust is a solitary, stay-at-home grasshopper. But suddenly, as in 1952, it may change character, gather an army, and start a gluttonous, migratory spree. Winds and double wings carry swarms from Africa to India, and some return. Replacements bred on the way refresh the teams like relay runners. Crop losses sometimes threaten nearly a fourth of the earth’s people with famine.Sinkiang is an alternate spelling of Xinjiang. French Somaliland is now the independent country of Djibouti.

10 points on the science of spreading the word
Recently, PopTech announced a new initiative called Editions, which explores an emerging theme at the edge of change from the perspective of some of the remarkable innovators shaping it. Over the next few weeks, we’ll be highlighting individual pieces from our first Edition, Person-to-person: Social contagion for social good. Today, we’re excerpting a contribution from political scientist and PopTech presenter James Fowler.
1. Good deeds are contagious
We naturally imitate the people around us, we adopt their ideas about appropriate behavior, and we feel what they feel. Acts of charity are no exception. In our 2010 generosity experiment, we showed that every extra dollar of giving in a game designed to measure altruism caused people who saw that giving to donate an extra twenty cents.
2. The network acts like a matching grant
That same experiment showed that contagious generosity spreads up to three steps through the network (from person to person to person to person), and when we added up all the extra donations that resulted at every step, we found that an extra dollar in giving yielded three extra dollars by everyone else in the network.
3. Messages get amplified when they spread naturally
People are bombarded by information and appeals every day, especially in our newly mobile and tech-centered society, so the effect of any one appeal to do a good deed may get lost. But don’t underestimate the effect of a broadcasting strategy. Our research on get-out-the-vote appeals suggests that the indirect effect of a message on a person’s friends is about three times larger than the direct effect on the person who received the message in the first place. The more you can get people to deliver the message naturally, the greater this multiplier effect will be.
4. Close friends matter more
When we studied behaviors like obesity, smoking, and drinking, we found that spouses, siblings, and friends had an effect on each other’s behavior, but next door neighbors did not. So any attempt to change people’s behavior should probably focus on motivating these “strong ties” rather than broadcasting to a wide range of weak connections.
5. Our real world friends are online, too
Although most relationships online are not strong (the average person on Facebook has 150 “friends”), we do tend to be connected to our closest friends online too. Therefore, it is possible to use online social networks to reach our real world friends to spread social good. If someone is suggesting friends to a person who could help spread the world, it is important to try to figure out which of his/her relationships are also likely face-to-face. We have done this using photo tags and frequency of communication online, both of which work relatively well.
