Thedistribution of village settlements along <strong>the</strong>coast exceeds <strong>the</strong> productive capacity of soils<strong>in</strong> <strong>the</strong>se areas, particularly <strong>in</strong> more heavilypopulated parts of Upolu. Samoa has little leftof its once large forest area ma<strong>in</strong>ly because ithas been cleared for <strong>agriculture</strong>. The rema<strong>in</strong><strong>in</strong>gforest is poor, degraded <strong>and</strong> mostly noncommercial.Much of l<strong>and</strong> planted <strong>in</strong> tarodur<strong>in</strong>g <strong>the</strong> export boom of <strong>the</strong> early 1990s wasab<strong>and</strong>oned after <strong>the</strong> arrival of taro leaf blight.Some is now be<strong>in</strong>g used to grow kava.Samoan <strong>agriculture</strong> is almost entirely smallholderbased. Only 1 per cent of hold<strong>in</strong>gs aremore than 40 ha., <strong>and</strong> 90 per cent are less than8 ha., usually divided amongst severalparcels. '6 Present l<strong>and</strong> use is a blend of twofarm<strong>in</strong>g systems where subsistence villagecropp<strong>in</strong>g (taro, bananas, o<strong>the</strong>r root crops,mixed vegetable gardens <strong>and</strong> various m<strong>in</strong>orcrops) has had a plantation cropp<strong>in</strong>g system(coconuts, cocoa) imposed upon it s<strong>in</strong>ceEuropean contact. Intercropp<strong>in</strong>g is oftenpractised, us<strong>in</strong>g various cultivars. Farrell <strong>and</strong>Ward (1962) described three zones of villagel<strong>and</strong> use; <strong>the</strong> structure of which rema<strong>in</strong>sessentially <strong>in</strong>tact today:a zone of coconut, much of which is old<strong>and</strong> little managed, located immediatelybeh<strong>in</strong>d <strong>the</strong> coastal villages <strong>and</strong> extend<strong>in</strong>g<strong>in</strong>l<strong>and</strong>;a mixed crop zone of cocoa, banana, taro,<strong>and</strong> m<strong>in</strong>or crops <strong>and</strong> a variety of fallowl<strong>and</strong>, <strong>in</strong>l<strong>and</strong> from <strong>the</strong> coconut zone; <strong>and</strong>a zone of taro of plots <strong>and</strong> fallow extend<strong>in</strong>gfrom <strong>the</strong> mixed crop zone to <strong>the</strong> forestboundary.Pr<strong>in</strong>cipal cropsTable 4 shows s<strong>in</strong>gle crop equivalent areas forSamoa's major crops, derived from <strong>the</strong> lastagricultural census (1989). There have been,however, quite dramatic changes <strong>in</strong> cropp<strong>in</strong>gpatterns due to <strong>the</strong> cyclones of 1990 <strong>and</strong> 1991<strong>and</strong> <strong>the</strong> arrival of taro leaf blight.Taro (Colocasia esculenta) is Samoa'straditionalsubsistence staple. Samoa's soil <strong>and</strong> climateoffer favourable conditions for taro, allow<strong>in</strong>g itto be harvested <strong>in</strong> 7 months or less. The 1989Agricultural Census <strong>in</strong>dicated that nearly15,000 hectares was planted <strong>in</strong> taro, of which76 per cent was pure st<strong>and</strong>, 23 percent mixedst<strong>and</strong> (ma<strong>in</strong>ly with ta'amu <strong>and</strong> banana) <strong>and</strong> 1per cent scattered plants. In <strong>the</strong> early 1990s, itwas estimated that taro accounted for 39 percent of Samoans' diet <strong>in</strong> Upolu <strong>and</strong> 43 per cent<strong>in</strong> Savai'i. It was also Samoa's major exportearner <strong>and</strong> was be<strong>in</strong>g exported <strong>in</strong> ever<strong>in</strong>creas<strong>in</strong>gquantities. Follow<strong>in</strong>g cyclones Ofa<strong>and</strong> Val, plant<strong>in</strong>g of taro significantly<strong>in</strong>creased to compensate for <strong>in</strong>come lost fromcoconuts <strong>and</strong> cocoa. Deregulation of market<strong>in</strong>galso allowed farmers to take advantage of goodmarket conditions. But <strong>the</strong> heavy dependenceon one crop brought with it its own risk. By<strong>the</strong> end of 1994, <strong>the</strong> rapid spread of taro leafblight had brought Samoa's subsistence <strong>and</strong>commercial taro <strong>in</strong>dustry to an abrupt halt. In<strong>the</strong> absence of effective controls, taroproduction had decl<strong>in</strong>ed to almost negligiblelevels. While <strong>the</strong>re has been some recovery <strong>in</strong>subsistence supplies, taro may never resume itsposition as Samoa's staple food crop.Giant taro (Alocasia macrorrhiza) or ta'amu istraditionally <strong>the</strong> fourth most important staple,after taro, bananas, <strong>and</strong> breadfruit. It is often<strong>in</strong>tercropped with taro or, <strong>in</strong> <strong>the</strong> drier areas,grown as a st<strong>and</strong>-alone crop. Ta'amu is bothdrought <strong>and</strong> cyclone resistant <strong>and</strong> is <strong>the</strong> mostimportant reserve food. While it normallytakes 18 to 24 months to reach maturity, animportant food security attribute of ta'amu isthat <strong>the</strong> tubers can be held <strong>in</strong> <strong>the</strong> ground up tofour years. A long drought <strong>in</strong> 1989 led to asubstantial depletion of ta'amu reserves <strong>and</strong>thus reserve stocks were low at <strong>the</strong> timecyclone Ofa struck <strong>in</strong> 1990.Yams (Dioscorea spp.) <strong>and</strong> tapioca (manihotesculentus) are m<strong>in</strong>or crops <strong>in</strong> Samoa.Traditionally, yams are consumed as a foodsupplement when available. Tapioca isregarded as a dist<strong>in</strong>ctly <strong>in</strong>ferior food that iseaten at times of shortages but o<strong>the</strong>rwise fed topigs. There has, however, been a dist<strong>in</strong>ct<strong>in</strong>crease <strong>in</strong> cassava consumption follow<strong>in</strong>g <strong>the</strong>taro leaf blight.Bananas (Musa spp.) have now replaced taro asSamoa's ma<strong>in</strong> subsistence crop. They areusually cooked green <strong>and</strong> eaten as a starch. In<strong>the</strong> early 1990s, <strong>the</strong>y normally accounted for23 per cent of food requirements <strong>in</strong> Upolu <strong>and</strong>16 per cent <strong>in</strong> Savai'i, with families consum<strong>in</strong>gone bunch per day on average 17 . Bananas isnow very much a subsistence17 Survey cited <strong>in</strong> Clarke, 1992:6916 Fairbairn, 1993
crop; accord<strong>in</strong>g to <strong>the</strong> 1989 AgriculturalCensus 87 per cent of households grow<strong>in</strong>gbananas did so only for householdconsumption. This was not always <strong>the</strong> case, fordur<strong>in</strong>g <strong>the</strong> 1960s <strong>and</strong> 1970s a significantbanana export <strong>in</strong>dustry to New Zeal<strong>and</strong>existed. A comb<strong>in</strong>ation of cyclone damage,disease <strong>and</strong>, most importantly, competitionfrom Ecuador <strong>and</strong> Philipp<strong>in</strong>es led to <strong>the</strong> demiseof this <strong>in</strong>dustry.Breadfruit (Ariocarpus altilis) planted aroundvillages is Samoa's third most important foodcrop. Dur<strong>in</strong>g <strong>the</strong> season, families on averageconsume 9 breadfruit per day on Upolu <strong>and</strong>10.5 per day on Savai'i. 18 Most breadfruitvarieties have two fruit seasons a year butseveral Samoan cultivars have three or evenfour seasons per year.Coconuts, which have long dom<strong>in</strong>ated<strong>agriculture</strong> <strong>in</strong> Samoa, have a central place <strong>in</strong>subsistence as a food <strong>and</strong> as a build<strong>in</strong>g <strong>and</strong>weav<strong>in</strong>g material, <strong>and</strong> also offer villagers alow-risk source of cash <strong>in</strong>come. Accord<strong>in</strong>g to<strong>the</strong> 1989 agricultural census, 96 per cent of allhouseholds were <strong>in</strong>volved <strong>in</strong> coconutproduction, mostly <strong>in</strong> small-hold<strong>in</strong>gs averag<strong>in</strong>garound 6 ha. The importance of coconuts <strong>in</strong>subsistence is evident <strong>in</strong> that 52 per cent ofhouseholds produced coconuts only for homeconsumption. Only 5 per cent producedcoconuts predom<strong>in</strong>ately for sale. Based on thiscensus, <strong>the</strong> World Bank (1991) estimatedhousehold coconut consumption to be 8,900tonnes copra equivalent, approximatelyequivalent to commercial copra, coconut oil,<strong>and</strong> coconut cream production. After years ofdecl<strong>in</strong>e, accelerated by recent cyclone damage,<strong>the</strong> non-subsistence coconut <strong>in</strong>dustry is nowexperienc<strong>in</strong>g a significant resurgence. In 1996,coconut products-copra, coconut oil, coconutcream, <strong>and</strong> fresh coconuts-were Samoa's ma<strong>in</strong>export by value, earn<strong>in</strong>g $16.4 million, or 66per cent of <strong>the</strong> total. This recovery can beexpla<strong>in</strong>ed by a comb<strong>in</strong>ation of factors The recovery of <strong>the</strong> productive base of<strong>the</strong> <strong>in</strong>dustry s<strong>in</strong>ce <strong>the</strong> 1990 <strong>and</strong> 1992hurricanes. The palms that survived <strong>the</strong>cyclones have now fully recovered withyields approach<strong>in</strong>g <strong>the</strong>ir normal level.While accurate estimates of permanenttree loss are not available, WESTEC put<strong>the</strong>ir losses at around 10 to 15 per cent 19 .There was some replant<strong>in</strong>g through abonus-plant<strong>in</strong>g scheme. The recovery of world market prices <strong>in</strong><strong>the</strong> last few years. The susta<strong>in</strong>ability of <strong>the</strong> coconut cream<strong>in</strong>dustry. Coconut cream production <strong>and</strong>export earn<strong>in</strong>gs have rema<strong>in</strong>edremarkably consistent over <strong>the</strong> lastdecade, despite adversity. The twoprivate coconut cream factoriescont<strong>in</strong>ued to operate <strong>in</strong> spite of <strong>the</strong>cyclones by import<strong>in</strong>g nuts fromTokelau, Tonga, <strong>and</strong> Fiji. The privatisation of coconut oilprocess<strong>in</strong>g <strong>in</strong>dustry.The loss of taro as a profitable crop forsmall holders.Mak<strong>in</strong>g copra <strong>and</strong> sell<strong>in</strong>g husked nuts has becomea profitable activity for Samoan small-holders,compared with alternative uses for <strong>the</strong>ir labour <strong>and</strong>l<strong>and</strong> resources. At <strong>the</strong> end of 1995, farmersreceived $715 per tonne of copra, at which pricecollect<strong>in</strong>g <strong>and</strong> mak<strong>in</strong>g copra generated a grossmarg<strong>in</strong> of $10-15 a day, 20 comparable to nonskilledwage rates.
