Aim: To identify, locate and discuss the impacts of climate change on agricultural expansion on Akhamb Island.
- To identify the main agricultural practices and/or activities done on Akhamb Island
- To state the effects of climate change on the agricultural practices and agricultural expansion on Akhamb Island
- To state and discuss ways of overcoming the effects of climate change
These are the methods used in carrying out the EarthCaching project:
- Appropriate information on the topic is first obtained from the library from journals, articles, books and the internet
- Interviews and surveys are carried out on Akhamb Island where some islanders from Akhamb Island are interviewed.
- Using GPS receiver to store points of interest where climate is seen affecting most.
- Digital camera is used to capture picture evidence of areas affected by climate change.
From the results obtained, it can be seen that climate change also has an impact on the sources of income on Akhamb Island. People on small and isolated islands rely heavily on the available resources and also on certain natural products so to earn an income to sustain their living on a relatively small land area with limited resources. The bar graph on figure 1 shows the different income sources for the people on Akhamb Island and that the main sources of income for the people were mainly from coconut (copra), kava, cocoa, pigs, root crops and others which includes carving, fishing and the operation of small shops on the island. In the year 2000, it can be seen that people rely on kava, coconut (copra) and root crops as the major sources of income. The selling of pigs, cocoa, fishing, carving and other artefacts were seen as not so important sources of income.

However, within a period of ten years later, figure 2 shows the bar graph of the main sources of income where there is a decline in the production of kava, copra and root crops and there is a rise in the other sources of income. This shows that as climate is changing and becoming more unpredictable where planting seasons are being distorted, the people on Akhamb Island tend to rely on other sources of income such as fishing, carving, weaving mats and baskets, and also rearing of pigs for commercial use. As the climate is changing and weather patterns are becoming more unpredictable and where tropical cyclones are more predictable in the country, farmers are not motivated since the results of their harvest is not so promising. Thus, farmers and people on Akhamb Island switch to other means of income sources so to provide them with an income so to sustain their living on the island.

People living on Akhamb Island are now experiencing one of the most upsetting moments of their life’s and that to escape from the effects of climate change, they should consider moving or migrating to the mainland and also seeking aid and assistance from the government so to aid them to settle down in a new environment. By changing the way to earn an income or change the ways in which to cultivate the land to produce more food is of no use since the effects of climate change will keep on accumulating and that there is less chance to be a successful farmer by living on Akhamb Island. As the population on Akhamb Island is increasing, there is a need for more food production so to gather for the feeding needs for the population. To increase food production, more space is required and it is seen that there is only limited space for agricultural expansion. Further expansion will result in failure of crop production since sea-level rise had caused certain areas of the flat and fertile land to become salinated which is not fit for agricultural production.
