Non-timber forest products: evolution, development and research.

A comprehensive review of the non-timber forest product (NTFP) sector from 1980 to 2022 was undertaken. The study employed a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, incorporating explicit keywords. The results indicate that NTFPs underwent significant evolution, including research and development changes, particularly following the Rio de Janeiro summit. Most published research originated from the United States, accounting for 24% of the total; Brazil and India each contributed 10% of the published research. We included 316 potential research items: 262 articles, 19 book chapters, 27 review articles, and eight conference papers. The review analysis highlighted that NTFPs are crucial in meeting food requirements, obtaining specific medicinal resources, and acquiring material inputs for rural households, serving as a safety net during agrarian distress. NTFPs play a crucial role in promoting the development of the bio-economy. In low- and high-income nations with abundant bio-resources, NTFP value chains are increasingly pertinent for generating revenue, enhancing livelihoods, and reducing poverty in forest dependent communities. Further, the analysis emphasized that NTFP consumption, utilization, and sales occur at the household level, and its comprehensive assessment is challenging, leading to the need for a reevaluation of approaches that include value chain analysis.
