Patterns in the Distribution of Southern African Terrestrial Tortoises (Cryptodira: Testudinidae)

Distribution maps for the ten southern African species of land tortoise have been prepared using published sources and recent museum records. Three hundred and thirty-six new records have been added to these maps by a recent Cape Province tortoise survey, and a further 65 of the older records have been re-confirmed. A relatively clear picture of the range of each species is now available, although the records in South West Africa are not yet adequate enough to resolve the problems posed by the vague localities published at the beginning of the century. The Cape Province of South Africa clearly stands out as the world's richest area in terrestrial testudinids

Persistence and changes in the peripheral Beles basin of Ethiopia

We have investigated the relevance of the notion of "peripheralism" in the Beles basin. In this lowland border area of Ethiopia, important investments require an evaluation of their socio-economic and ecological impacts in the light of Ethiopia's Climate-Resilient Green Economy (CRGE) strategy. We contrasted literature of different periods with field observations. In the middle and lower parts of the basin, the Gumuz people traditionally practised shifting cultivation. Resettlement of highlanders is particularly linked to water and land resources. A large irrigation project was initiated in the 1980s, but vegetables and fruits face post-harvest losses. Large water transfers from Lake Tana since 2010 affect the movement of people, the hydrogeomorphology, and ecology of the river. In several parts of the basin, the settlers' economy now dominates. Many Gumuz became sedentary but maintained their agricultural system, particularly in the south of the lower basin. Land titling allowed allocation of "vacant" areas to transnational or domestic investors. As a result, the semi-natural vegetation is frequently replaced by open cropland, leading to decreased carbon storage and increased soil erosion. This and water abstraction for irrigation jeopardise hydropower production, in contradiction with the CRGE objectives. Despite the recent developments, the contrasts in economic activity make the core-periphery dichotomy to remain actual in the Beles basin. The resettlements and permanent cropping tend to make the upper basin part of the core. However, the installation of a transit road and commercial farms in the lower basin do not allow to consider that a non-peripheral integration has taken place
