With over 14 million hectares allocated, Vietnam’s forest and forestland allocation has been one of the largest natural resource decentralization programs in the developing world over the last three decades. Given this remarkable achievement, critics are concerned about the low rates of household tree planting investment and question the roles and effects of land institutions on investment.

Since the global crises in the 2000s, many foreign and domestic actors have acquired large tracts of land for food and biofuel crop cultivation and other purposes in Africa, often leading to the displacement of the African people living on customary land. The weak customary land rights of ordinary African people have been viewed as one of the main factors making it possible for various land-grabbers to exploit customary land with different purposes.

Knowledge of hydrologic connectivity is important to grasp the hydrological response at a basin scale, particularly as changes in connectivity can have a negative effect on the environment. In the context of a changing climate, being able to predict how changes in connectivity will affect runoff and sediment transport is particularly relevant for land-use planning. Many studies on hydrology, geomorphology and climatology have been conducted in the Lake Tana Basin in Ethiopia, which is undergoing rapid development and significant environmental changes.
