The Participatory 3-Dimensional Modeling (P3DM) integrates participatory resource mapping, and spatial information to produce a stand-alone scaled relief model, which has proved to be a user-friendly and a relatively accurate research, planning and management tool. This model is constructed through the active participation of a given community with facilitation by mapping experts and hence derives its name, Participatory 3-Dimensional Model. It is easier to understand 3-dimensional (3D) models as compared to other types of maps as it adds a third dimension which makes it easy for visualization and communication. With the application of Participatory 3-Dimensional Modeling (P3DM) communities can better plan the management of their resources because they will have more knowledge about resources available. The participatory approach to community management in SNP is not a new concept. There are several activities in Sagarmatha region that involved the participation of the communities in the planning and development. Through these exercises, communities understand the major problems and provide them opportunity to find means to solve these problems. It is expected that, local communities will have deeper understanding of the geography of the region, improved communication skills and stronger cohesion and consensus among them. The general objective of this document is to assess the feasibility of Participatory 3-Dimensional Modeling (P3DM) in Sagarmatha National park (SNP) and to answer the basic questions on how P3DM can be used in planning and management of the park. P3DM will be developed by the communities and would result in a physical 3D representation of an area of the park. This in turn would increase the understanding of the situation and qualities and strength of the decision-making process of the communities of the region. Also the model would be a useful means of information communications to the visitors.
