The Moroccan land policies are ineffective in overcoming sustainable development constraints, in particular those related to land statute dualism, to property structure and to land access modes and exploitation. The agricultural land fragmentation associated with privatisation process increases transaction costs and raises coordination problems. Anti-commons are amongst these management problems characterised by the prevalence of exclusion rights and the reduction of common resources rent, requiring thus more coordination. The aim was to highlight the limit of agricultural private investments due to low availability of agricultural lands despite the privatisation of collective and Domanial lands in relation to anti-commons problems. This paper reviews the management and the fragmentation of agricultural lands in Morocco. The anti-commons theory was introduced in relation to agricultural land governance by reviewing recent scientific contributions in the field land management. Land concentration and fragmentation are impeding on agricultural reform efforts. Anti-commons solution requires the same background as the Commons since they both are collective action problems, and has its roots in property rights restructuration in order to promote consolidation opportunities and rural development. The difficulties related to joint ownership, registration and multiple institutions involved in land management encumber agricultural development policies.
