摘要

该研究强调了建立农林复合系统的必要性,该系统将减少尼日利亚东南部克罗斯河州Obudu牛牧场的薪材短缺问题。利用参与式农村评价(PRA)方法,收集了关于当地作物类型、人们已知的薪材种类、他们偏爱特定薪材种类的原因、采伐数量和采伐人员的一般信息。定性和描述性统计,如矩阵排序技术,简单的比例/百分比和表格在数据分析中使用。结果表明,在低投入条件下,农林业系统中木本树种与一年生作物的整合可提高山地和稀树草原生态系统生产系统的可持续性。农林业具有短期和长期的保护和社会经济利益,并将在很大程度上制止侵蚀、洪水、生态的不利变化、土壤生产力下降、有用生物物种(植物和野生动物)的丧失和整个林地的逐渐恶化(砍伐森林)等问题。适合这些地区的稳定的本土和原型农林复合系统是可用的。然而,它们需要更广泛的测试和使用。环境科学学报,Vol. 6 (1), 2007: pp. 53-64

Agroforestry systems for mitigating the problems of fuelwood scarcity int he Montane/Savanna ecosystems: A case study of Obudu Cattle Ranch, South-Eastern Nigeria
The study highlights the need for an agroforestry system that will reduce the problem of fuelwood scarcity in the Obudu Cattle Ranch settlement of Cross River State, South-Eastern Nigeria. Using Participatory Rural Appraisal (PRA) methodology, general information on Local crop types, fuelwood species known to the people, their reasons for the preference of particular fuelwood species, the quantity extracted and who does the harvesting was collected. Qualitative and descriptive statistics such as matrix ranking techniques, simple proportions/percentages and tables were employed in the data analysis. Results show that integration of woody species with annual crops in agroforestry systems can enhance sustainability of production systems in the montane and savanna ecosystem under low input conditions. Agroforestry has short and long-term protective and socio-economic benefit and would go a long way in checking the problems of erosion, flooding, adverse change in ecology, decline in soil productivity, loss of useful species of organisms (plants and wildlife) and the gradual deterioration of the entire forest lands (deforestation). Stable indigenous and prototype agroforestry systems suitable for the regions are available. However, they need wider testing and use.
