The tribal people cannot let out their patta land on lease neither they can alienate the proeprty in any manner.

Especially since the land is situated in the forest area, you may not get permission for access to the land through the forest area. 

As the tribal land owners are managing their access to their land by their own arrangement through the forest and also the forest authorities are turning a blind eye to this arrangement, they may not face any problem. 

However if the tribal land owner decides to lease out the patta land, then it may attract the sore eyes of the authorities concerned and they may refuse permission without complying to the rules and other conditions in this regard. 

Any lease to the non-tribals even of the Government land situated in scheduled area is in violation of Scheduled Area Land Transfer Regulation.  

The provisions of  forest conservation Act also may be invoked to prohibit the land owners to seek path access to the leased out land to the non tribals.

The procedure for establishing an eco-resort on tribal patta land and the departments involved in granting permissions can vary depending on the specific regulations and laws of the region where the land is located. However, I can provide you with a general overview of the steps typically involved in such a project:

Consultation and agreement: The first step is to consult with the landlord and reach an agreement on the terms and conditions of the partnership. This may include discussing profit sharing, lease duration, responsibilities for development and maintenance, and any other relevant aspects. It is advisable to engage a legal professional to draft a formal agreement to protect the interests of all parties involved.

Tribal department consultation: Since the land is tribal patta land, it is crucial to engage with the tribal department or similar authority responsible for tribal welfare and land rights. They can provide guidance on the specific requirements and procedures for development on tribal land. They may also require documentation such as a no-objection certificate (NOC) from the local tribal community or governing body.

Environmental Impact Assessment (EIA): Given that the property is located in a forest area, it is likely that an Environmental Impact Assessment (EIA) will be necessary. This assessment evaluates the potential environmental impact of the proposed development and provides recommendations for mitigating any negative effects. Consult an environmental consultant or firm experienced in conducting EIAs to guide you through this process.

Land use conversion and permissions: Depending on the regulations in your region, you may need to obtain permission for converting the land's use from agricultural to non-agricultural or commercial purposes. The specific department responsible for granting such permissions can vary, but it could be the revenue department or the local municipal or development authority. You may need to submit an application, along with the necessary documents and fees, to initiate the conversion process.

Building permits and construction: Once you have the necessary land use conversion, you will need to obtain building permits and other construction-related approvals from the local municipal or development authority. This involves submitting detailed architectural plans, structural designs, and other relevant documents for review and approval.

Other permits and clearances: Depending on the nature and scope of your eco-resort project, you may need to obtain additional permits and clearances from various departments. This can include fire safety clearances, food and hygiene licenses, liquor licenses (if applicable), permits for signage, and any other permits required by local regulations.
