| Abstract | |
The use of multiple forest resources has been pointed in the scientific literature as one of the most win-win strategies for conservation and local development. However, the limitations of this approach have not been completely determined. The unavailability of diverse non-timber forest products (NTFP) in a local context as well as the lack of motivation and ability of people to collect such products limits the success of this strategy. In this regard, our study aimed to evaluate the contribution of different factors to the above mentioned aspects, including the feasibility of the collection of multiple NTFP and its potential generation of monetary income. We evaluated the environmental, the socioeconomic, the cultural and the perception factors in seven sites of the central Amazon, at Mamirauá Reserve. In a local context, the economic potential and availability (presence and abundance) of NTFP provided by fruits and seeds of five important species found specifically in that region (açaí, buriti, camu-camu, andiroba and murumuru) were examined. In an individual level, we evaluated the personal motivation and ability of collecting the multiple NTFP, in addition to the perception factor (characterized by the pleasure of collecting). Further, we investigated the socioeconomic and cultural factors in the context of the domestic units. In order to measure the availability, 24 transects where established in seven Amazon sites. Environmental factors such as solar radiation, topography and the amount of organic compounds in the soil were also accessed. In order to estimate the economic potential, we considered the abundance of the species, the annual rate of fruits and seeds production and the product prices. To better address the individual motivation and ability in collecting the products and the socioeconomic, cultural and perception factors, surveys and interviews were performed. A total of 195 interviews were done: 75 at the domestic unit level and 120 at the individual level. Our study demonstrates that the presence and abundance of the species vary among the different localities, being the E. precatoria and A. murumuru the common species found in all the localities. Moreover, the availability of NTFP vary seasonally, according to the characteristics of fructification of every species. Hence, the availability of the NTFP might be the first limiting factor compromising the generation of monetary income. Changes in the environmental factors were found to affect the concentration of the individual of the species, which show an aggregated distribution. In all the localities, the vast majority of the subjects demonstrated to be interested in collecting the species, except the murumuru. We observed a higher motivation of people in collecting that products with a higher consumption and commercial rates. Finally, we found that a significant amount of subjects in the seven sites were able to collect all the products evaluated, regardless the difficulties underlain the collection process. In conclusion, our data suggest that the main limiting factors for the collection of multiple NTFPs in the seven localities of the Mamirauá RDS are related to a small number of trees or palms and the lack of motivation in collecting, which is triggered in turn by the lack of pleasure of collecting as well as for the non-habit of consuming and for the difficulty of commercializing.
