Palau – Adaptation Context
~ 85% population reside in low-lying coastal areas of Palau
Taro is the main staple crop
Planted in low-lying areas.
Salt water intrusion impacting adversely on taro (staple) crop
About 7-9mm/yr
![Page 5: PEF Recognising hybrid solutions TO BUILDING RESILIENCE: pacc palau](https://reader035.vdocument.in/reader035/viewer/2022081519/5681357f550346895d9cdd51/html5/thumbnails/5.jpg)
Palau – Adaptation Context
Projected to increase by 5-15cm (high confidence PCCSP)
Low lands are abandoned due to high salinity
Food imports in Palau have grown by 133% in the last decade, while the population has increased by 20%

Performance of traditional dykesResults - mixedUsing only traditional materials with soil no longer stops intrusion
More secondary dykes had to be build.
Also there is now the use of plastic or tarpaulin materials and sandbags to help keep out the salt water.
![Page 14: PEF Recognising hybrid solutions TO BUILDING RESILIENCE: pacc palau](https://reader035.vdocument.in/reader035/viewer/2022081519/5681357f550346895d9cdd51/html5/thumbnails/14.jpg)
Clearing of waterway from the hill
BEFOREAFTERTraditionally farmers rely on dykes and
flushing to keep the salt water out or flush out salt water in the plantations.

Women are responsible for Taro Planting

More secondary dykes have to be build to prevent intrusion
![Page 19: PEF Recognising hybrid solutions TO BUILDING RESILIENCE: pacc palau](https://reader035.vdocument.in/reader035/viewer/2022081519/5681357f550346895d9cdd51/html5/thumbnails/19.jpg)
Traditionally men are not allowed into taro patches. Now they need to assist the women to deal with
salinity challenges
![Page 20: PEF Recognising hybrid solutions TO BUILDING RESILIENCE: pacc palau](https://reader035.vdocument.in/reader035/viewer/2022081519/5681357f550346895d9cdd51/html5/thumbnails/20.jpg)
Lessons…Natural solutions are best but may
not be enough thus the need to be open to hybrid solutions to better adapt
Traditional practices need to change to deal with new challenges brought about by climate change
Be flexible and open minded to adaptation solutions as the situation demands
