The coffee sector is a key pillar of agricultural development in Son La province, with over 21,400 hectares under cultivation and an annual production of 35,000–45,000 tons of green coffee beans. However, Son La currently lacks specific mechanisms to implement waste management policies in coffee processing. The widely practiced wet processing method generates large volumes of organic-rich wastewater and coffee husk by-products, while most household-scale and cooperative processing facilities do not have appropriate treatment systems. The direct discharge of waste into the environment is causing localized pollution, affecting community health and increasing environmental management pressure at the local level. Son La province has issued Resolution No. 128/2020/NQ-HĐND to encourage investment in agriculture and agro-processing, including support for processing facilities. However, in practice, support mechanisms for wastewater treatment and coffee by-product recycling have not yet been clearly operationalized. Pilot models implemented by the Northern Mountainous Agriculture and Forestry Science Institute (NOMAFSI) in Mai Son district demonstrate that low-cost biological treatment solutions and coffee by-product recycling can be effectively applied at cooperative and small-scale processing levels. Based on these results, NOMAFSI proposes integrating coffee waste management solutions into provincial policies through three main actions: (i) developing technical guidelines for processing facilities; (ii)…
This leaflet explains how farmers in northwest Vietnam process coffee husks into organic fertilizer. It details the benefits—improved soil health, reduced environmental pollution, lower fertilizer costs, and support for sustainable farming—and provides step-by-step guidance on composting. The method involves mixing coffee husks with manure, lime, phosphate, urea, and a microbial solution, ensuring proper moisture, and covering the pile to retain nutrients. It was published in June 2025 by NOMAFSI with ALiSEA support, based on a successful farmer experience.
This leaflet describes an ecological system in Son La, Vietnam, for treating wastewater from coffee cherry processing through solid separation, anaerobic and aerobic treatment with yeast, and final storage, enabling safe reuse for irrigation and producing organic fertilizer.
This video demonstrates how to use Trichoderma as a bio-control agent to protect banana plants from Fusarium wilt (Panama disease),. The guide explains the different stages of the disease and provides a practical method for prevention,. By soaking banana suckers in a mixture of one packet of Trichoderma and 5 liters of water for 20 minutes before planting, farmers can safeguard their crops from the start,. This biological approach helps prevent the spread of fungus in the plantation and ensures healthier, more resilient banana trees.
This dataset showcases "The 'Do All' Biochar Wood Vinegar Kiln", a practical and efficient design that allows small-scale farmers to produce both biochar and wood vinegar from agricultural waste. Developed at the ECHO Asia Farm in Chiang Mai, Thailand, the kiln supports sustainable farming practices. This initiative is part of the ALiSEA Small Grant Facility 2023, which aims to strengthen biochar producer networks across the region.
This dataset includes two short videos produced under the Youth Agroecology Caravan (YAC) programme in Cambodia, a field-based learning initiative that supports young farmers to explore agroecological practices through farm visits and peer exchange. The videos relate to key topics addressed during the training, including reducing the use of chemical inputs, making use of farm resources, and diversifying production systems to support more sustainable farming and livelihoods.
This technical leaflet provides practical guidelines and practices for establishing and managing a semi-intensive local pig raising system. It covers aspects such as housing setup, paddock fencing, feeding strategies, and crop production to support pig nutrition. Emphasizing agroecological principles, this guide promotes environmentally friendly practices that maintain soil health, biodiversity, and resource efficiency. Designed for small to medium-scale farmers, the leaflet aims to optimize animal welfare, improve feed efficiency, and enhance farm productivity through cost effective and well-planned methods.
This ALiSEA leaflet provides essential information on the breeding, rearing, and feeding of frogs in both commercial and breeding environments. It covers key aspects such as selecting breeding frogs, managing water quality, feeding practices, and ensuring healthy growth. By following these guidelines, you can ensure optimal conditions for frog development and production.
