Jag har haft förmånen att besöka Kiambere plantagen två gånger – både 2008 och sedan 2012. Här nedan finns några av mina bilder från besöket där. Den är anlagd vid Kiamberesjön där Kenyas elbolag har byggt en stor damm och haft problem med erosion.
De bjöd in Better Globe att anlägga en testplantage för att se om träden kunde hindra jorderosionen. Hela projektet har varit en enormt stor framgång. Om du vill läsa mer om Kiambere plantagen, bläddra neråt för att läsa texten saxad från Better Globe Forestrys hemsida.

Från Better Globe Forestrys hemsida om Kiambere
Better Globe Forestry Ltd started its first fieldwork in Kenya at the end of 2006, at Katithini, on a 300ha site by Lake Kiambere in eastern Kenya. The Tana and Athi Rivers Development Authority (TARDA) owns the land. TARDA has a powerful incentive to entrust the land to BGF for afforestation, as Lake Kiambere is one of the major hydro reservoirs for generation of electricity for Kenya.
The lake is fed by Kenya’s biggest river, the Tana that originates from the slopes of Mount Kenya. Its tributaries find their way to the lowlands through densely populated areas, carrying plenty of soil from erosion. TARDA has a catchment protection programme, but the waters of the river are very brown every rainy season. The situation is compounded by intense erosion around the lake, where literally thousands of tonnes of soil are washed into the lake after every major downpour. This fills up the dam, decreasing its lifespan, and hence reducing the capacity for provision of affordable electricity.
BGF has demonstrated that it can stop erosion on the lakesides completely, by planting trees and blocking erosion gullies with thousands of check dams. The tree species planted on this 300ha pilot site are mukau (Melia volkensii) and neem (Azadirachta indica)and, shortly, Acacia senegal. Mukau, the principal species for BGF, is planted for its superior mahogany-type timber. BGF’s trials have shown that it can be planted year-round, provided it receives adequate care and irrigation. Growth is excellent, with seedlings reaching 3 metres in height, after barely one and a half years.
BGF has planted neem for its oil, which is used in biological pesticides, and has medicinal properties.
BGF has established a trial plantation of different provenances of Acacia senegal. It produces the valuable gum arabic, a stabilizing agent that has many industrial applications in the food, beverage and printing industries. All these species are adapted to the local environment, that is, hot and semi-arid, with irregular rainfall. In particular, Melia volkensii and Acacia senegal are extremely drought resistant.
BGF employs between 50 and 200 people in the pilot plantation, depending on the work, which in turn depends on the season. There is overall supervision by BGF staff, security by guards to avoid theft from the store, and intrusions by goats and other livestock that would damage the trees, the nursery and various works in the plantations. These works include the whole cycle of land preparation, tree planting and plantation maintenance. BGF is the biggest employer in the area, with payment of salaries signifying an important injection of cash into the local economy.
