The pUipose of this paper was to 'assess the extent to which thediflerent rainwater harvesting systeniS, are used in Tanzania. The findings show that there is a widespread practice of rainwater harvesting in Tanzania. Rainwater hmvestillg with storage of wate!' for livestock has received govemment SUppOit in the past . . However, rruzny storage reselvoir~ have been destroyed by siltation. On the other hand rainwater hmvesting for crop production has llOt received an adequate SUppOit from research and extension services. Therefore, although farmers are practiciizg rainwaterhmvesting, they are faced with sh01tage of appropriate technolo giesand know | en_US |
