Colleagues said he tweeted more than any professor they knew, and Calestous Juma’s tweets covered a swarm of things. Income inequality, and a free-trade area for Africa, you might expect. Those were the subjects he taught at Harvard: getting poorer countries, especially in Africa, to grow and thrive was the obsession of his life. But he also tweeted about a wheelchair that could climb stairs, the increasing size of steaks, and the maximum number of goats seen eating up in a tree. He was extra-delighted to send out a New York Times editorial, from 1878, about Thomas Edison’s new “aerophone”: “Something ought to be done about Mr Edison, and there is a growing conviction that it had better be done with a hemp rope.”

Calestous Juma, a prominent global advocate for sustainable development in struggling countries, particularly in his native Africa, could trace his passion for technological innovation to his arduous childhood in colonial Kenya.

A professor of the practice of international development, and a writer of great range, Calestous Juma promoted technology for the poor and vulnerable throughout the world. He also wrote a book explaining why people are wary of innovation, and delighted his more than 100,000 Twitter followers by retweeting cartoons that ribbed those who are resistant to science.

This article contributes to the understanding of transitions towards low carbon societies in the developing world. While adding extensive empirical insights from the status of energy transitions in two countries faced with major energy challenges, the Philippines and Morocco, the authors contribution enquires what role external actors like international donors in general, and Germany in particular, can play in such transitions.

"To harness the globally available technologies, African leaders will need to take into account the multisectoral dimension of African agriculture and pay particular attention to the urgency of investing in rural infrastructure, higher agricultural training and creation of regional markets."

Africa is yet to adopt full scale technology-led development. Steve Mbogo spoke to the Director of the Belfer Center's Science, Technology, and Globalisation Project and professor at Harvard University Calestous Juma on the opportunities that await the continent as a late comer.

"The challenge is finding an entry point for fostering science, technology and engineering cooperation between China and Africa. An obvious starting point is agriculture. There are two reasons for this suggestion. First, agricultural transformation was one of the first major programs launched by China after the adoption of the 1982 constitution."

"The Rio+20 process is an important reminder of the urgency to guide global production and consumption patterns with sustainability principles. Sadly, there is really no genuine global institution that is championing sustainable development. The vision that inspired Rio has been supplanted by two extreme positions. The first is a group that believes economic growth will have trickle-down benefits for the environment. The environmental camp has successfully replaced the spirit of Rio with a one-sided agenda that leaves little room for recognising the central role that human wellbeing plays in natural resource management."

If African countries can't plant genetically modified crops to produce more and healthier food, vulnerable populations will be at risk, argues Calestous Juma.

Recent national trends in investments in global energy research, development, and demonstration (RD&D) are inconsistent around the world. Public RD&D investments in energy are the metric most commonly used in international comparative assessments of energy-technology innovation, and the metric employed in this article. Overall, the data indicate that International Energy Agency (IEA) member country government investments have been volatile: they peaked in the late 1970s, declined during the subsequent two decades, bottomed out in 1997, and then began to gradually grow again during the 2000s.
