<strong>Solomon</strong> <strong>Islands</strong>: Analysis of Poverty from 2005/2006 HIESand in <strong>the</strong> highest three deciles 21.9% of HH use gas burners. This suggests that <strong>the</strong> cost of purchased fuel is adeterrent to its use and that firewood is easily accessible (at least currently), ei<strong>the</strong>r in <strong>the</strong> market or from collection.It is only in <strong>the</strong> higher expenditure deciles where “clean 16 ” fuel becomes a major source of cooking energy. Therecent fuel and power prices rises will have streng<strong>the</strong>ned this preference for fuelwood.126. In <strong>the</strong> rural areas <strong>the</strong>re is very little use of energy sources o<strong>the</strong>r than firewood; virtually 100% of cooking is donewith firewood in <strong>the</strong> poorest HH, and even amongst better-off households only around 3.1% of high expenditureHH use gas. Details of fuel usage for cooking in both Honiara and <strong>the</strong> rural areas are provided at Appendix TablesA4 & A5.127. Thus while <strong>the</strong>re may be significant health benefits (especially for women and young children) from <strong>the</strong> use of“clean” energy sources for cooking, <strong>the</strong> cost of such fuels compared to <strong>the</strong> “free” source of firewood is likely tobe difficult to overcome. Changing to clean fuels might also require significant changes in traditional cookingmethods and food types. Any change will <strong>the</strong>refore likely need to be slow and gradual.128. The nature of power for lighting inHoniara is shown Chart 19. Amongst <strong>the</strong>lowest expenditure households, in both<strong>the</strong> Honiara and rural areas, kerosene is<strong>the</strong> most widely used power source forlighting. In <strong>the</strong> rural areas this appliesacross all deciles, averaging 89.5%amongst <strong>the</strong> poorest HH and even 87.9%amongst those in <strong>the</strong> highest expendituregroups. For a small proportion of ruralhouseholds, around 2.6% of those in <strong>the</strong>highest three deciles, solar energy is alsoused as a source of lighting.129. For Honiara HH <strong>the</strong> use of electricity forlighting increases with <strong>the</strong> higher deciles; in <strong>the</strong> poorest HH only 40.9% are connected to <strong>the</strong> power system while 88.6%of those in <strong>the</strong> highest three deciles are connected. In <strong>the</strong> lowest three deciles 56.4% of households use kerosene.Details of power usage for lighting in Honiara and <strong>the</strong> rural areas are provided in Appendix Tables A6 and A7. These show<strong>the</strong> proportions of households using eachtype of power by decile and by source ofpower.7.8 Access to Water and Sanitation130. The next three charts look at access towater.

<strong>Solomon</strong> <strong>Islands</strong>: Analysis of Poverty from 2005/2006 HIESand sanitation in Honiara and <strong>the</strong> ruralareas are provided in Appendix TablesA8 through A12. The data indicates thataround 27.4% of households in <strong>the</strong> ruralareas are using unsafe or unprotectedprimary sources of water in terms ofpublic wells (21.9%), streams or rivers(5.5%). This compares with an average of23.5% of HH overall.131. Even amongst better-off HH a highproportion still rely on unsafe sources;some 20.3% of <strong>the</strong> top three deciles usepublic wells, rivers and streams as <strong>the</strong>irprimary water source.132. For those in Honiara <strong>the</strong> town reticulatedsupply or a similar piped source is mostcommon, Chart 22. Amongst lowexpenditure HH, just over sixty percenthave piped water, rising to 85% of thosein <strong>the</strong> highest expenditure groups. Evenin Honiara, however, that still means thatalmost 30% of <strong>the</strong> poorest HH are relyingon unsafe water sources.133. Around 13.2% of Honiara HH in <strong>the</strong> lowestthree deciles use public wells as <strong>the</strong>irprimary water source compared to anaverage over all Honiara HH of 7.4%. Also 3.3% of <strong>the</strong>poorest HH rely on rivers/lakes/streams as a primarysupply source.
