Some people are vulnerable in terms of land ownership, in other words they are actors who typically experience insecurity as far as their rights to develop land and natural resource are concerned. However, one may wonder whether the concept “vulnerable groups” is not used by development actors in an indiscriminate way. The so called vulnerable groups do not appear as homogenous social categories as they are alleged to be and any group of actors can sink into a situation of land insecurity. This could apply, even to those who are not classified as vulnerable groups.
