Anyone who has walked outside on a sunny day knows that forests and trees matter for temperature, humidity and wind speed. Planting trees speaks to concerns about climate change, but the directly important aspects of the tree-climate relationships have so far been overlooked in climate policy where it relates to forest.
That, at least, is the conclusion of a new review. The authors suggest that the global conversation on trees, forests and climate needs to be turned on its head: the direct effects via rainfall and cooling may be more important than the well-studied effects through the global carbon balance.
Yet, current climate policy only recognizes the latter. While farmers understand that trees cool their homes, livestock and crops, they had to learn the complex and abstract language of greenhouse gasses and carbon stocks if they wanted to be part of climate mitigation efforts. Not anymore, if the new perspectives become widely accepted.Read more
The 22nd UN climate conference (COP 22) held in November in Marrakech, Morocco’s ‘Ochre City,’ was all about action.
Action not only to reshape the path of development in order to curb global temperature rise as a result of climate change, but also to sustainably feed and provide for a growing global population. The actions are part of countries’ commitments of the 2015 Paris Climate Change Agreement, which came into force on 4 November 2016, just days before the Marrakesh conference kicked off on 7 November.
A common way to restore a degraded forest is to plant seedlings and nurture these into full trees. Indeed, to most people restoration and tree-planting (with native species) are virtually synonymous. Planting and nurturing tree seedlings over a wide area, however, can be an expensive and labour-intensive affair. Not to mention the decades or even centuries it takes before seedlings grow into trees.
Another common path to restoration is to simply protect a degraded forest from further degradation, often by fencing it off. Over time, lost tree cover will return through natural regeneration. This option is a relatively inexpensive, but it can also take centuries to achieve full restoration and the environmental benefits it brings.
Fig trees were here when dinosaurs first roamed the planet. And today, just as they did 80 million years ago, Ficus species continue to bring nourishment, shade, water and numerous other gifts to people and plants. What’s more, these trees may help us claw our way out of the ecological conundrums we currently find ourselves in—deforestation, species loss, and even climate change.
In a gripping 224 pages of eloquent writing, Mike Shanahan’s first book, ‘Ladders to Heaven: How fig trees shaped our history, fed our imaginations and can enrich our future’, brings us the fascinating story of fig trees. From the age of dinosaurs, to pre-history and the age of exploration, and into the present times, the reader learns how these trees shaped the planet and fascinated philosophers, conquerors and commoners alike.

Kimutai Maritim, the Assistant Director of Veterinary Services in Kenya, was the chief guest at the launch of Traditional ethnoveterinary medicine in East Africa: a manual on the use of medicinal plants.
A veterinary epidemiologist with long experience in the Kenya livestock sector, Maritim congratulated the authors on the publication. He said the book was timely and important, and it described important plant species, some of which may be facing local extinction in Kenya. Read more. . .
Is it enough to recommend tree species to farmers? Or even to supply them with the right seedlings and advice on growing them?
Across Africa bold campaigns, such as the African Forest Landscape Restoration Initiative (AFR100), are underway to get more trees into farming landscapes, as a means to restore land, protect watersheds, and meet people’s food and energy demands sustainably. The success of these programs will be greatly influenced by farmers’ decisions to plant, keep and nurture the trees for the long haul. And as it turns out, these decisions depend heavily on the ecological and socio-economic realities farmers find themselves in, which vary widely. Read more. . .
The soil is the “living, breathing skin of our planet.” It is the basis of food production and essential for clean water, health, greenhouse gas capture and numerous other functions that support life on earth.
Soil biodiversity is intimately connected with all terrestrial life. Thanks to advances in technology and global scientific cooperation, huge strides have been made in our understanding of the dazzling diversity of life forms beneath our feet; and especially that of microscopic bacteria, fungi, and nematodes that are invisible to the naked eye.

A large, old Faidherbia albida tree with a metre-plus diameter stored the equivalent of the CO2 emitted by 8 cars over one year.These useful trees play an important role in carbon sequestration, a critical part of the effort to reduce greenhouse gas emissions linked to climate change.
The evidence is clear: For big gains in crop production, our landscapes must become more hospitable to some of the planet’s littlest creatures— its pollinators.
Bees, birds, butterflies, moths and some small mammals transfer pollen from flower to flower, causing fruit to set. This environmental service of pollinators is what secures the harvest of a huge proportion of the world’s food production.
At an invited talk at the Nairobi headquarters of the World Agroforestry Centre (ICRAF) on 8 January 2016, Kenyan naturalist and entomologist Dino Martins, the Executive Director of the Mpala Research Centre and Chair of the Insect Committee of Nature Kenya, delved into the intimate links between the world’s food security and pollination.

In a ‘Letter to the Editor’ published in the Guardian Development Blog, Professor Roger Leakey urges a closer look at agroforestry’s potential as a pathway for both mitigating climate change and fighting hunger, malnutrition and poverty.
Leakey, who serves as the vice-chair of the International Tree Foundation, outlines a three-step action plan that involves:
Using simple biological approaches to rehabilitate degraded farm land and improve crop yields;
Planting local, highly favoured, traditionally important food trees to reduce hunger and malnutrition; and
Setting up new cottage industries to process and add value to these products, creating business and job opportunities to further improve household livelihoods. Read more. . .
