This study is aimed at studying the customary land laws and tenurial practices of the communities of the Nigerian Lower Benue River valley.  These communities are the Idomas and the Tivs  of Benue state, and the Alagos, Eggon, Mada, and Gwandara peoples of Nasarawa State.  The methodology adopted was a survey approach which incorporated primary data captured through questionnaire and interviews. The work has shown that in the area of study, all the land were acquired originally by settlement on virgin land.  All the communities studied, except Alago, recognise inheritance as a means of acquiring land. All land in Alago community is held purely communally and not by families. In Alagoland a member of the community can be dispossessed of his portion of land for misbehaviour.  In all the communities studied, the main mode of obtaining land by family members, is through allocation to adult males. In Tiv community, the allocation is on the basis of stirps (mothers’ portions). Partition is unknown among the communities studied. Pledge is recognized in all the communities studied, except among the Madas and the Gwandaras, who only recognize pledge of economic trees. When a pledgee or a customary tenant leaves the land in Idomaland and in Tivland, he can come back to the land to reap economic trees he planted on the land.  Thus, the principle of quic quid plantatur solo solo cedit does not apply in Tiv and Idoma communities. In the other communities, the matter is not as clear cut; it will be subject to negotiations or prior agreement.  Customary tenancy is recognized in all the communities studied except Alago. Alienation is by consultation and consent of family members and the head of the family or community.  All the communities studied do not recognize long usage or adverse possession as bestowing title on a stranger.  All the communities studied recognize the role of the family head, who must be a male member of the family. He must be consulted in every land transaction, but his refusal to consent does not nullify the transaction. In all the communities studied, women cannot head a family and are not entitled to portions of land. The conclusion from this work is that the land law and tenure practices of the six communities studied differ slightly from one another, but differ significantly from those recognized among the Yoruba custom, which is the most researched of all communities in Nigeria. Most of the concepts of customary land law among the Yorubas do not apply to the communities studied. It is recommended that women should head families and should be entitled to portions of land to avoid discrimination outlawed by the 1999 Constitution. The Alago communal holding custom should be dismantled to allow for development. The principle of quic quid plantatur should apply in Benue and Tiv communities so that former tenants and pledgees do not encumber the land they have left.

Customary land tenure practices are the accepted rules of practices in particular communities in terms of the customs, customary laws and norms which guide how land is used that avoid friction among the people. The communities in this study are agrarian area in the middle belt of Nigeria where land is primarily used for farming. These communities are the Idomas and the Tivs of Benue State, and the Alagos, Eggons, Madas and Gwandaras of Nasarawa State.  These communities are a continuous land mass cut only by River Benue. 
Customary land law is worth investigating despite the existence of the Land Use Act  in Nigeria.  This is because the Act itself recognizes customary law in land administration . Another reason for studying customary land law in Nigeria at the present time is because the provisions of the Act are not known in the rural areas and even in the urban and sub-urban areas where the provisions of the Act are known, tjhey are not appreciated. This is most evident in the Area courts of Northern Nigeria where majority of land cases are instituted and decided on the basis of customary laws. 
This study is aimed at studying the customary land laws and tenures of six communities in the Nigerian Lower Benue River Valley. The study was designed to investigate whether the customary laws in the communities are the same with those of the more researched communities in Nigeria. The second aim is to investigate whether the customary laws and practices with regard to land differ among the communities inter se. There are other ethnic tribes in the two States
(Benue and Nasarawa), such as the Igedes in Benue State and the  Ebirra Koto, Yeskwa,  Afor and Gwari in Nasarawa State. However, the communities selected for this study are the more prominent ones occupying a continuous block of land, broken only by River Benue.
