Farmer Advisory




The Chamka App is built for rural farmers to help improve access to Information and Communication Technology (ICT) and farming techniques, provide extension services and technical support via an online chat messaging service that helps farmers connect to more suppliers and buyers. 

Capability and features

The Chamka app provides agriculture e-learning and technical advice on farming, offers remote and online extension services, and an eMarket platform for smallholders to sell their produce and for buying agricultural input supplies at better prices. 

Agricultural experts help farmers overcome technical challenges, offering advice on how to maintain their crops and how to respond appropriately to climate emergencies. This information is delivered via pictures, videos, voice and texts through the app. 

Input retailers use the Chamka app for the virtual marketplace platform to promote and post products to sell. Input suppliers can manage their products and receive sale orders directly from farmers.

Progress to date

As of 2022 there are more than 42,000 users already registered and active in using Chamka App to access online training videos. Around 6,000 users have used extension service support through the support service and around 4,000 users have already accessed the virtual market to purchase input supply via the app.

Chamka is currently rolled out in 20 provinces in Cambodia. In this initial phase, Chamka mainly focuses on extension services to provide direct technical support for farmers and virtual markets for farmers to access input supply via the app. Chamka’s vision for the long term is to support not just smallholder farmers but also big enterprises with large scale production that require more automation and technology to support farm productivity on a daily basis.

Chamka was developed in 2020 in cooperation with the International Fund for Agriculture Development (IFAD), Ministry of Agriculture Food and Rural Affairs – Korea (MAFRA), Ministry of Agriculture Forestry and Fisheries –Cambodia (MAFF), the Agriculture Service Programme for Innovation, Resilience and Extension (ASPIRE) and SwissContact. Chamka is also in collaboration with GIZ Agrinnovation Fund (AIF) to support traceability and access to markets for farmers.
