Read the passage below carefully and answer the question that follows:
In the lush highlands of Ethiopia's Kaffa region, traditional timber logging for fuel has long accelerated forest degradation. To stem this ecological decline, local environmental cooperatives introduced dense bamboo cultivation as a sustainable alternative for charcoal production. Unlike indigenous hardwood trees, which require several decades to mature, native highland bamboo reaches full harvestable height within three to four years and regenerates naturally without replanting. Recent field surveys indicate that communities adopting bamboo charcoal have reduced their reliance on old-growth forest timber by nearly forty percent over a five-year period. However, commercial scaling remains constrained by local credit markets; smallholder processors frequently lack access to capital needed for high-efficiency carbonization kilns. Consequently, many processors continue using rudimentary earth mounds, which release high volumes of smoke and yield low-density charcoal that commands lower market prices. While international non-governmental organizations have sponsored technical workshops, financial institutions still classify these community-led eco-enterprises as high-risk borrowers due to non-standardized land tenure records.
Based on the passage, what can be inferred about the primary factor limiting the profitability of smallholder bamboo charcoal processors?
- An inability to secure formal credit prevents processors from acquiring advanced kilns that produce higher-value charcoal.Answer
- BLocal financial institutions refuse to lend money because bamboo cultivation severely depletes highland soil nutrients.
- CHighland bamboo takes several decades to reach maturity, creating severe shortages of raw processing material.
- DInternational non-governmental organizations have withheld technical training from smallholder processing cooperatives.
