 Indonesia's easternmost province of Papua is home to one of the world's largest forest areas, nearly 41 million hectares, an area almost three times the size of England. Yet Indonesia has been reported to have one of the highest deforestation rates in the world, with the Indonesian Forestry Ministry revealing that the country lost 3.5 million hectares between 2003 and 2006, or more than 1 million hectares a year. The majority of deforestation has occurred on the islands of Sumatra and Borneo, however many observers believe Papua will be next. Ministry figures say Papua lost nearly 80,000 hectares of forest between the same period, however some environmental organisations estimate much larger rates of up to 300,000 hectares of forest lost per year. As the government decides how it will develop Papua, experts are looking at how this can be done in a way that makes most sense for the economy, local people and the natural environment. The Centre for International Forestry Research, CIFOR, the Agricultural Research Centre for International Development, SIRAD, and Conservation International Indonesia have been conducting research on development in Papua for the last eight years. In 2010, the scientists began researching the potential to involve local communities in the land use decisions of local governments through a project called Collaborative Land Use Planning in the context of climate change in Indonesia. The team of scientists focus their research on the Mambrambo region in the northern part of Papua province. Development is one of the most important goals for people in Papua and more especially in Mambrambo. Our project doesn't aim to say what is good, what is wrong. What we try to do was to bring people together and to discuss about that. The project is helping the local community to get in touch directly with their own governments to prepare about conservation and also development that really meet the green economic goals and strategy for the governments of Mambrambo Raya. Land Use Planning is the main tool used by the government to manage the area with maps playing an important role in developing official land use plans. So far, the local people who have the rights to this territory and possess a high level of ecological knowledge have not been included in decision making. The scientists visited Mambrambo region over 10 days in 2012 to introduce a Mambrambo government and community to methods such as group discussions, interviews and participatory mapping that the scientists developed to assist them in creating a land use plan together. The workshop for us was a way to put everybody, all the stakeholders together and to discuss around the results that we brought back. I think that was something that never happened in Mambrambo Raya before and everybody was quite enthusiastic with that. And I think the outcome of the workshop was valuable for the local government for villagers also in the end. We had to set up a plan to build this land for the national land use. The land use plan was also part of the integration and we explained that almost all the conservative areas have land ownership that is indeed the property of the land use. And we had to take care of that. What we see now is the land use plan. For local government, they thought at the beginning that villagers didn't understand anything about RTR or about land use plan, about maps. And they were really surprised to see how confident were the villagers to explain their own maps and to locate themselves in this big territory and to say this is what we want and for what reason. One of the key tools used was map making. The government found it could use these maps to develop land use strategies and the local people recognized them as an effective negotiation tool. Unlike a report, the participatory map can be easily understood by local people as it is presented in a visual way to describe what really matters for local community in terms of biodiversity, forest resource and landscape as well as how people use their land at present and what they plan for the future. We can show that map, if there is a problem or a problem that comes in, we can also see whether the land is good or bad. We can know exactly. This is where the land is. This is where we find food. This is where I have to go through. This is where I have to go through. If we hope for the future, it is better to be used by the government in a better way. This map is important. I am here to help the local government in making plans. Apart from the map, we can see the border between the village and the village but also the potential in it. For example, in the forest of Bakau, in the forest of Sagu, in the land of Udang, in the land of Kerang and so on. This is a picture of the government for example, in Yoke village, to save the economy or save the people's land in Yoke, we can start from here. This will help us a lot. From here, we will go out to the village of Yoke. We have used this company for transportation from Lake Tabarissia to upper-ware river impacted on the environment. The scientists had the opportunity to visit the channel to observe the situation. This is the end of Lake Tabaresia, and this is the place where the villagers complained about the activity 40 years ago of a company exploring oil. And who digged the channel that linked a power with Tabaresia lake behind me. And we can see when we go out of this channel that even on the lake close to here, the soil, the ground is going out of the water and the trees are growing there. So in a few years the lake will be smaller and smaller. The local people use maths to illustrate how a channel from Yoke village to Lake Rombabai instead of Mambrambo river would enable Yoke village access to the greater regency and simultaneously be better for the environment. This is because a river already exists between Yoke and Rombabai and only requires enlarging the river bed. It also avoids silting, which would have occurred between the channel from Yoke to Mambrambo river if it was made. This is the Jerni river, so it won't be used for dhampak. Even if there is a flower, the fish from Lake Tabaresia and Lake Tabaresia can go there. This fish is used for the future of our grandchildren who will come, not only us. It is hoped that this proposal has been able to provide the Mambrambo community together with the government with the tools to ensure better collaborative land management for conservation and development for the future.
