Homegarden Systems of Indonesia, Sri Lanka, and Vietnam

2013•12•09

Numerous studies have been conducted on homegarden systems by researchers from different disciplines and countries, but most focus on ecological structure or specific benefits provided by the ecosystem of a selected study area. However, a paper co-authored by several UNU researchers shows how these homegardens are ecologically, socially, and economically diversified and how beneficial they are to human well-being.

The study also investigates the impacts of drivers on homegarden systems in rural areas in three countries. These studies involved comprehensive literature reviews and field surveys. Four types of ecosystem services — provision, regulation, cultural, and support — were assessed and compared. The team found that traditional homegardens maintain high ecosystem diversity especially in rural areas; however, recent socio-economic changes are converting subsistence-oriented homegardens into commercial ones.

Future challenges for further research, the authors note, include how to enhance the resilience of homegarden systems against socioeconomic and global climate changes by integrating traditional homegarden systems, modern technology, and the global economy.

Below is a photo essay based on the homegardens the team visited.

In Java, where homegardens cover 20 percent of the total land area, the study focused on a typical traditional homegarden system known as Pekarangan. This is generally managed by individuals who grow a mix of products, including timber, vegetables, and fruits. Photo © Hideyuki Mohri.

This farmer, near Hanoi, Vietnam, grows more than 50 different kinds of medicinal plants, fruit, and vegetable crops, in addition to raising fish and other livestock using the Vuon-Ao-Chuong (VAC) system. This integrated agricultural system (which translates to “garden-pond-livestock”) originated in the Red River Delta and midlands of Northern Vietnam. Implementation of Vietnam’s Doi Moi Policy in 1986 promoted the VAC system with an aim to increase and stabilize the nutritional standards of poor rural people. As a result, integrated farming has spread throughout Vietnam especially in irrigated lowlands, rain-fed uplands, and semi-urban areas. Almost 44 percent of all households in Vietnam now use such a system. Photo © Hideyuki Mohri.

Some communes have village-scale VAC systems that connect each household to a community farm and lake creating community-scale systems that can grow more products suitable for sale to larger markets.

Kandyan homegardens play an important role both as a link to agricultural and natural landscapes and as a source of income and nutrients for the country′s rural midlands population.

Like this farmer in Kandy, many of Sri Lanka’s farmers are now seeking international organic certification for their crops. There are growing efforts to promote Sri Lanka’s homegarden products to the international market through organic certification programmes in the European Union and the United States.
