The NAGA foundation aims to establish Hydrologic Corridors, wherein re-greening and restoration ofthe landscape interacts with regional rain-bringing wind patterns to intensify the local hydrologic cycleto a point that a permanently greener and more productive ecosystem can be sustained. The initialsearch area, as defined by NAGA, targets the Kenya-Tanzania border region and identified fourpossible Hydrological Corridors. This report supports an objective prioritisation of potentialintervention locations in this larger domain. Therefore, readily available, geographically explicitinformation on soil, vegetation, hydrology and climate, as well as institutional settings that may affectthe likelihood of success of such projects, were collected and analysed, and some climate-modellingexperiments were performed.Combining the findings of the four themes: hydrology, soil restoration, climate, and institutions, andranking the four potential corridors objectively in order of priority, favours re-greening projects in theTanzanian corridors could provide the best starting point: especially the most eastern one. In thisarea, many applicable land management options exist in combination with a high potential forrestoring soil organic matter, the highest rainfall recycling potential in the more favourable long rainyseason, and the apparent reliability of the Tanzanian governments at both national- and at locallevels. The GIS data facilitate further focus on this particular corridor in search of specific projectlocations
