Development of a database of material flow analysis for agro-food processing craft villages in Red River Delta of Vietnam
Introduction
Craft village definition: - 30% households in productions and stable for more than 2 years - Abiding by State legislation [source: Circular No 116/2006/TT-BNN]
- Productions at level of family: takes place at household or designated area Agro-food processing craft villages: raw materials (and products): rice (liquor, noodle, vermicelli), soyabean (tofu), arrowroot (starch, glassnoodle), cassava (starch, liquor)
11 provinces in Red River Delta

before 1930 1954 – 1978 1978 – 1985 1986 - 1992 1993 - now
Development of craft villages and environmental problems
(adapted from Dang Kim Chi, 2005: „Làng nghề Việt Nam và môi trường“ (Craft villages Vietnam and Environment))
Problem statement: - Environmental problems: starting after 1990, alarming in 2000s until now. Food villages: Water and wastewater crisis! - Increasing energy demand - Ineffective env. regulations - Research projects and much governmental effort booming in 2000s until now…
=> Problems now and future: water and energy crisis, env. degradation-related problems (social conflict, health, economic) => Potential in resources and energy recovery
Development of a database of material flow analysis for agro-food processing craft villages in Red River Delta of Vietnam
Objectives
- Development of a Material Flow Analysis (MFA) database of goods, energy and elements of Carbon, Nitrogen, Phosphorous - suggest solution for sustainable production as well as for environmental and resources management
Methodology DATA COLLECTION
Primary data Secondary data
Field work Laboratory analysis
pH, TS, VS, COD, TN, TP, TOC
production process
interviews sampling
rice vermicelli, glass noodle, arrowroot starch, cassava starch, rice sheet
DATA PROCESSING (excel, STAN, statistic tools)
MFA database (energy, goods and elements of C, N, P)
production processes
Literature Procductions: rice liquor, cassava liquor, rice noodle, tofu Concentration of N, P, COD from other sources than craft villages => INHAND project „integrated water concept for craft villages in Vietnam“
region Red River Delta extrapolation process
