Ecosystem Services in Natural Dye Tree Species-based Agroforestry - A Review
Abstract
The integration of natural dye-yielding tree species into agroforestry systems offered a sustainable strategy for balancing environmental protection with rural economic growth. These systems delivered a multiple ecological advantages like enhancement of biodiversity, carbon storage, improvement of soil functionalities and efficient regulation of water resources. Incorporating dye-producing trees within farming landscapes also strengthened climate resilience by improving ecological balance, minimizing land degradation, and supporting pollinator populations. Furthermore, diversified agroforestry practices increased the overall functionality and sustainability of agricultural ecosystems. Beyond environmental advantages, natural dye trees provided valuable raw materials for textile, handicraft, and cottage-based industries, thereby creating livelihood opportunities for rural communities. The rising preference for eco-friendly and biodegradable products has increased the relevance of plant-based dyes as sustainable substitutes for synthetic colouring agents. This review examined published studies related to the ecological and socio-economic contributions of dye-producing tree species under agroforestry systems. The analysis highlighted their important role in sustainable land management, ecological restoration, and promotion of environmentally sound production systems. However, the study also identified several limitations, including inadequate scientific information on underutilized dye species, low public awareness regarding their economic and ecological importance, weak marketing support, and limited policy initiatives for their wider adoption. Overall, the incorporation of natural dye-producing tree species into agroforestry systems can serve as an effective approach for conserving natural resources, improving climate adaptability, supporting biodiversity, and enhancing the rural bioeconomy through sustainable production practices.
