The economic reform “Đổi Mới” in 1986 has rapidly increased the number of craft villages in Vietnam, especially in the Red River Delta (RRD) leading to environmental degradation. This article presents an assessment of environmental and resource issues of agro‐Food Processing Craft Villages (FPCVs) in RRD using a refined approach to material flow analysis focusing on consistent quantification of uncertainty with particular attention to secondary and empirical data that are often faced in material flow analyses in transition economies. Material flows of agro‐Food Processing including eight types of production were examined and linked to activities of private Households, Rice Cultivation, and Pig Farming in a model called Red River Delta. Materials investigated were Goods (i.e., total materials), organic carbon (org.C), nitrogen (N), and phosphorus (P). The findings reveal material cycles are almost entirely open, that is, the materials used in FPCVs do not recycle within the region. From ∼10.5 million tons/year of imported Goods used for agro‐Food Processing, final products and utilized materials account for minor fractions (∼5%, by weight). Conversely, the majority (88%) is directly discharged. Materials accumulated as stocks represent 1% of Goods (100,000 tons/year), 21% of org.C (∼34,000 tons/year), 42% of N (∼1,300 tons/year), and 57% of P (∼300 tons/year), whose substance concentrations vastly exceed natural resilience capacities. Although agro‐Food Processing accounts for negligible material shares in Red River Delta, FPCVs pollution is severe at local levels due to the location of home‐based production. Several options for closing material loops at various system scales are recommended for environmental and resource management of FPCVs. The material flow analysis results provide a database that may be used as a decision support tool for production establishments in craft villages and relevant authorities in setting priorities on environmental planning and resource management.

越南红河三角洲农业食品加工手工业村的区域物质流动行为 

1986年的经济改革“ĐổiMới”迅速增加了越南手工艺村的数量，特别是在红河三角洲（RRD）地区，导致环境恶化。本文使用一种改进的方法对物质流进行分析，对RRD中的农业食品加工工艺村（FPCV）的环境和资源问题进行了评估，重点是对不确定性进行一致的量化，尤其要注意物质中经常遇到的次要和经验数据转型经济体的流量分析。对农业食品加工的物质流（包括八种生产类型）进行了检查，并将其与私人家庭，水稻种植和养猪业的活动联系起来在一个叫做红河三角洲的模型中。调查的材料为货物（即全部材料），有机碳（有机碳），氮（N）和磷（P）。调查结果表明，材料循环几乎是完全开放的，也就是说，FPCV中使用的材料不会在该区域内循环使用。每年用于农业食品加工的进口货物约为1050万吨，最终产品和利用的材料占很小的比例（按重量计约为5％）。相反，大多数（88％）直接排出。累积的库存物料占货物的1％（100,000吨/年），组织C的21％（〜34,000吨/年），N的42％（〜1,300吨/年）和P的57％（〜300）吨/年），其物质浓度大大超过了自然复原力。尽管农业食品加工由于红河三角洲的物质份额微不足道，由于家庭生产的地点，FPCVs在当地的污染严重。对于FPCV的环境和资源管理，建议使用几种选择来关闭各种系统规模的物料回路。物质流分析结果提供了一个数据库，该数据库可以用作工艺村和相关机构在确定环境规划和资源管理优先级时的生产机构的决策支持工具。本文符合http://jie.click/badges中所述的金–银JIE数据开放性徽章的要求。
