Title: Development of a Model for Improving Nabag Forest Reserve for Participatory Management and Carbon Development
Author: Abu Zwaid, Mona Mohammed Rakhi
Abstract: The present study was conducted in Nabag forest reserve located in south Kordofan State. The objective of the study was to develop participatory forest management in a forest reserve which could be used as a model for environmental protection on a sustainable system. The system aims at the rehabilitation of Nabag forest reserve in order to improve the livelihoods of poor farmers around the reserve. The data collection was based on forest survey, inventory and community interviewing. The forest was surveyed by GIS (Geographical information system) taking coordinates for mapping. Ground inventory of the forest was based on systematic line-plot sampling technique with circular sample plots of 0.1 hectare each, systematically distributed at 100 meters along lines and 100 meters between plots resulting in 10% sampling percentage. In each sample plot, every tree species was recorded and each tree was measured for diameter at breast height (DBH) in cm and height in meters. The social survey was conducted using a questionnaire to assess people perception towards the forest reserve and its benefits and management. The forest map was produced using the GIS coordinates and ARC Map. The tree data were analyzed using a computer program soft ware Excel and SPSS (Statistical Package for Social Sciences). The results of the forest survey provided an accurate map of the forest which was not significantly different from the original forest map. The results of the forest inventory showed that the present situation of the forest has low average stocking density of 109 trees/ha, while the pilot plantation has 360 trees per hectare taken as the standard stock for gum Arabic. The low stock of trees is indicative of low biomass and carbon contents, based on average volume of a mature tree of 0.068 cubic meters. The social survey results showed the high willingness of local communities around the forest to participate in the management and rehabilitation of Nabag forest reserve as IV indicated by 79% of the respondents. The majority of the target group (80%) preferred Hashab planting than other tree species in the forest, because it allows agro-forestry system and because it has multiple benefits including soil improvement as mentioned by 79% of the respondents. A model was developed for the participatory forest management, based on the inventory results and people opinions where the forest is divided into 20 management units based on the rotation of hashab of 20 years. Management circles and yield regulation were recommended in order to approach sustainable system of the multiple benefits. The management was proposed to accommodate collaboration and partnership between the communities and the management authority of the forest reserve in order to improve the forest stocking density and the monitoring system.
