SDG 1. No poverty

In Timor-Leste, we use Earth observation data to help small coffee growers

Coffee is grown by about 37% of the population in Timor-Leste, in the shade of trees in mountainous areas that are very difficult to access. We are working with ESA, the European Space Agency, using Earth observation data to monitor coffee plantations, improve quality and productivity, and increase the revenues of coffee growers to help combat poverty.

Timor-Leste is the Eastern part of the Timor island. It is located between Indonesia and Australia. It has a population of about 1.2 million people. 75% are food insecure and about 42% are poor.

I work in the Agriculture and Rural Development sector at the Asian Development Bank. I am currently based in Hanoi, Vietnam.

Poverty is mostly concentrated in rural areas. Timor-Leste depends highly on food imports. Agriculture is the primary source of livelihood for about 80% of the population, and is mostly subsistence agriculture. Timor-Leste is very vulnerable to climate change and disasters.

Coffee production in Timor-Leste started during Portuguese times. It is the largest non-oil export. Coffee is grown by about 37% of Timorese households. Most coffee growers are poor. Improving coffee quality and productivity is a key to improving their income.

The European Space Agency and the Asian Development Bank have partnered up to use Earth observation data for monitoring coffee plantations in Timor-Leste.

This allows us to intervene quickly and provide appropriate support to coffee farmers. This way of monitoring from above is very effective because it is less costly, much quicker and gives us the full picture.

This agroforestry system helps preserve the environment. The shade trees help stabilize the soils on steep slopes, increase the infiltration of rainfall to aquifers, absorb carbon, and provide a habitat for a wide range of flora and fauna. It also helps improve soil fertility by fixing nitrogen, and provides a source of edible fruits.

This pilot experience from Timor-Leste can be used in other countries in Southeast Asia. It can be easily applied to other crops and farming systems to improve people’s livelihoods.

My message to visitors of the Space for our Planet exhibition is based on a quote from anthropologist Margaret Mead who said:

“Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has”.

Let’s protect our planet – we can all make a difference.

Coffee plantations are grown as part of an agroforestry system where coffee plants are planted under the shade of larger trees. Using satellite images provided by Sentinel 2, we were able to map out the vegetation and coffee plantations and monitor the health of coffee plants and trees.

In Timor-Leste coffee cultivation is the second economic income after oil in the country. National authorities need to conduct a census of plantations and monitor their status to apply a national coffee rehabilitation plan. Red areas indicate coffee plantations cultivated under two species of tree (Albizia and Casuarina) at the end of year 2019. The light blue polygon indicates the area of study included into the provinces of  Ermera, Aileu and Ainaro where most of the coffee cultivations are concentrated. The coffee plantations were obtained by applying Machine Learning and Deep Learning algorithms to one year of images from the European Union's satellites Copernicus Sentinel-1 and Sentinel-2.
