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.

Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns.

The dramatic fall of oil prices is set to jeopardize both the U.S. ambition to become a big gas exporter by the end of this decade and the long-awaited development of a global gas market.

The world can only meet its future food needs through innovation, including the use of agricultural biotechnology, Belfer Center development specialist Calestous Juma said in an address to graduates of McGill University, Montreal, Canada.

Since their commercial debut in the mid-1990s, genetically designed crops have added about $100 billion to world crop output, avoided massive pesticide use and greenhouse gas emissions, spared vast tracts of land and fed millions of additional people worldwide, Juma said during the graduation ceremony where he received an honorary doctorate. He asked the graduates to embrace innovative sciences that alone will make it possible to feed the billions who will swell world population in decades ahead, especially in developing countries.

"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."

Extracting, delivering, and disposing water requires energy, and similarly, many processes for extracting and refining various fuel sources and producing electricity use water. This so-called 'water–energy nexus', is important to understand due to increasing energy demands and decreasing freshwater supplies in many areas. This paper performs a country-level quantitative assessment of this nexus in the MENA region.
