摘要

由于东非国家面临天然林日益遭到破坏和人工林数量日益减少的问题,并且由于减轻贫穷仍然是一个主要的发展目标,因此,学术界和实际方面正在注意种植软木的小农从事的农场林业。然而,对这些国家软木木材价值链的详细审查很少。本研究讨论了坦桑尼亚北部梅鲁山地区农场林业过早采伐的迹象,并从农村木材贸易商的角度审查了木材锯切和销售对针叶木材农民的经济意义,城市和贸易中心的木材场零售商很大程度上依赖农村木材供应的信息。正如农村木材贸易商的交易战略所反映的那样,发现过早采伐通常是贫穷的结果,或者较少是作为农民获得足够林地的收入最大化的一种方式;因此,出售早熟树木并不一定对农民不利。然而,我们也发现,小直径树木的销售对农民从成熟树木中获得的销售收益份额产生了负面影响,特别是当这些成熟树木数量较少,并且在单笔交易中与小直径树木放在一起时。此外,在目前的个体化生产和加工下,农民没有组织成生产者组织。虽然在迅速城市化的区域经济中,小农林业肯定会从农村以外地区产生收入,但需要仔细调查销售收益如何在这些交易的不同农村参与者之间分配。

Economic significance of premature harvesting for farm forestry smallholders in the Mount Meru area, Tanzania
As East African countries face increasing destruction of natural forests and diminishing stocks of forest plantations, and as poverty alleviation continues to be a major development goal, academic and practical attention is being paid to farm forestry undertaken by smallholders growing softwood. However, there are few detailed examinations of the softwood timber value chain in these countries. The present study discusses signs of premature harvesting in the farm forestry in the Mount Meru area of northern Tanzania, and examines the economic significance of timber sawing and marketing for softwood farmers from the perspective of rural timber traders on whom timber yard retailers in urban and trading centers rely greatly for access to information on rural timber availability. As reflected in rural timber traders’ transaction strategies, premature harvesting was found usually to be a result of poverty, or less frequently as a way of maximizing income for farmers with access to sufficient land for woodlots; thus, the sale of premature trees is not necessarily disadvantageous to farmers. However, it was also found that the sale of small-diameter trees negatively affects the farmers’ share of sales proceeds from mature trees, especially if these mature trees are sold in small quantity and are put together with small-diameter trees in a tree set for a single transaction. Moreover, farmers do not organize themselves into producer organizations under the current individualized production and processing. Although smallholder forestry certainly generates income from outside rural areas in the rapidly urbanizing regional economy, careful investigations are needed as to how the sales proceeds are distributed among the different rural participants in these transactions.
