Tea Production Areas and Forest Distribution in Kenya
The micro-climate associated with
forest areas is often a critical factor
in growing cash crops. In East Africa,
tea is grown in areas adjacent to montane
forests where conditions for tea
production are optimal due to constant
moisture levels, air temperatures
between 10° and 30° C and soil temperatures
between 16° and 25° C. The
high moisture levels in these montane
forests combined with the high heat
capacity of water reduces the day...

Number of trees planted, world map - UNEP Billion Tree Campaign, May 2008
The UNEP Billion Tree Campaign represents a unique worldwide tree planting initiative, aimed at empowering citizens to corporations and people up to presidents to embrace the climate change challenge. By 2008, 18 months since the launch of the initiative, the campaign has managed to catalyze the planting of two billion trees, double its original target. The campaign, spearheaded by the UN Environment Programme (UNEP) and the World Agroforestry Ce...

Multiple stressors in small-scale agriculture
There is a need to develop agricultural policies that both reduce emissions and allow adaptation to climate change that are closer to carbon-neutral, minimize trace gas emissions and reduce natural capital degradation. Important questions include how emissions from agriculture and forestry can be effectively reduced, how to produce food with greater input efficiency, and less GHG emissions, how can agriculture, agroforestry and forestry best adap...

There is great potential to restore carbon in tropical agricultural soils through management
practices that, in the right circumstances, can also increase productivity. Agroforestry
can offer particularly large carbon gains, although it can increase water demand.
Agricultural carbon sequestration policies will need to be tailored to particular circumstances
to allow farmers to benefit.
