Key research findings and final reflections

Following a busy few weeks of write-up and last-minute incorporation of results, my MSc thesis has been submitted! Though challenging at times, it has been an enjoyable and rewarding experience overall. I’m grateful that I got the chance to carry out my placement in Vietnam, and my supervisors in CIAT and NUI Galway were supportive and encouraging throughout.

Have a look at the results section for an overview of the key research findings. Continue reading “Key research findings and final reflections”

Project presentation to Irish Aid Vietnam

Yesterday my two classmates, my CIAT supervisor Tiffany Talsma, two of her CIAT colleagues and I met with Irish Aid Vietnam at the Irish Embassy in Hanoi. Irish Aid support the Vietnamese Government’s Socio-Economic Development Plan as well as funding the global CCAFS program. Below is a short Video summary of Irish Aid in Vietnam.

Challenges of remote sensing for mapping plantations

The past week I was helping to compile information and guidance for the Terra-I team to allow them to start mapping the cocoa farms from the polygons they have been given. One of the biggest challenges they will face is distinguishing tree plantations from other vegetation such as secondary forests with a high degree of accuracy. This was backed up by my review of the available literature on this topic on Tuesday.

Spectral confusion (reflectance from vegetation) with native vegetation is a well-known challenge in agroforestry and tree crop systems, particularly in mapping cocoa, shade coffee, oil palm, and evergreen rubber tree plantations. Tree crops are grown using full sun or low shade methods are less likely to be misclassified than when they are grown in densely-shaded agroforest.

Climate change projections for cocoa growing regions

My first week in CIAT started with a meeting to discuss aspects of my project with those who are currently involved with cocoa research in Indonesia. It was interesting to see how my research will fit in with other ongoing or completed studies within CIAT. There are other research projects looking at cocoa in Indonesia at regional scales. For my project I will be working to produce a national level assessment of carbon stocks and carbon footprint of cocoa, bringing together all this regional data.

Now is a good time to offer a comment on climate change impacts on cocoa in Indonesia. Over the next century, South East Asia is predicted to experience increased temperatures, increased variability and intensity of rainfall in particular at higher altitudes, and increased risks of high intensity and frequent extreme weather events such as cyclones and droughts (IPCC, 2014). Climate change is already having an impact on cocoa crop yields in Indonesia (Witjaksono, 2016). Continue reading “Climate change projections for cocoa growing regions”
