Community-based co-management (CBCM) mechanisms for forest management have matured through the development of new economic
analysis and common property theory. However, while many local CBCM mechanisms have been initiated in Chinese Natural Reserves,
there are few objective, data-based evaluations of whether these mechanisms improve forest conservation and local livelihoods.
This research uses Baishuijiang National Natural Reserve (BNNR) as a study case to evaluate China’s current CBCM mechanisms.
The evaluation is based mainly on three criteria: efficiency, equality and sustainability of project operation. Survey data
indicate that local CBCM mechanisms provide a wide-participation platform for local villagers, associated administration managers,
research institutions and NGOs to join in forest resource protection work while improving local livelihood. CBCM projects
have also facilitated a reduction in forest resource dependency, the improvement of household income and encouragement of
local people to participate in forest resource protection. Our analysis suggests that most CBCM organizations have made progress
in efficiency, equity and sustainability. However, further study should focus on how to deal with the lingering problems of
inequity in responsibility and rights among CBCM committee members, poor distribution of benefits, insufficient program-design
and management expertise, faulty information dissemination, and insufficient capital investment. 相似文献
During the 11th Five Year Plan period,China improved its policy system for the overall strategy of regional development,and established and completed the policies intended for the promotion of regional cooperation and interaction.Thereupon,regional development in China took on a series of positive changes such as the enhancement of coordination.During the 12th Five Year Plan period,China will fully implement and continuously improve the policy measures for development in its four major regions,strengthen differentiated guidance to different regions in line with the planning for major function-oriented zones,and accelerate the establishment of basic systems that facilitate coordinated regional development. 相似文献
The adverse impacts of lead and cadmium exposure on health outcomes have been reported in the past. Few studies have been conducted on the relationship between lead and cadmium exposures and disability. We evaluated whether lead and cadmium exposures were associated with functional dependence including the total number of disabilities, activities of daily living (ADL), instrumental activities of daily living (IADL), leisure and social activities (LSA), lower extremity mobility (LEM), and general physical activities (GPA) in an elderly population. A total of 5513 eligible subjects were enrolled in the study from the National Health and Nutrition Examination Survey 2001–2006. Serum lead and cadmium exposure assessments were performed using atomic absorption spectrometry. Functional dependence was assessed by 19 structured questions. The relationships between lead and cadmium exposures and functional dependence were investigated using by multivariable linear regression models. Q2, Q3, and Q4 of lead exposure were significantly associated with the total number of disabilities, with β coefficients of ??0.62 (95% CI ??0.99, ??0.24), ??0.64 (95% CI ??1.02, ??0.26), and ??0.81 (95% CI ??1.19, ??0.42), respectively. This relationship remained significant in males. Furthermore, we analyzed the relationships between lead and cadmium exposure quartiles and various functional dependence metrics, and we determined that lead content was significantly associated with decreased ADL, LEM, and GPA (p?<?0.05) and cadmium content was inversely associated with ADL (p?<?0.05). Our study demonstrated a strong relationship between exposure to lead and cadmium and functional dependence in an elderly population.
