Selective esterification of carbohydrates via stannylene complexes

Abstract

Mangrove forests in Kenya are estimated to cover about 50,000-60,000ha.However non-sustainable utilization,over-exploitation of resources and conversion to other land uses principally for fish pond, salt pans, infrastructure development are drastically removing this resource base at a highly alarming rate. Loss of mangrove forests in turn is affecting the local economy as indicated by shortage of firewood, building poles,decreasing fishery resources, destruction of corals and exposure of human settlements to tidal waves. Conservation alone is not enough. The damage can be overcome by rehabilitation and reafforestation of mangrove areas. A mangrove reafforestation project to rehabilitate degraded areas, restock denuded mudflats and transform disturbed forests into uniform stands of higher productivity was launched in October 1991 at Gazi bay. Basically three artificial regeneration techniques were employed:(a) use of propagules (seeds, (b) use of saplings (less than 1.0m height) and (c) use o (smaIl trees' up-to 2.0m height .
