1 Introduction

Nontimber forest products (NTFPs) as part of forestry sectorin any economy have always been supportive for many ruraldwellers that live within and around the forests estates Inmany rural communities the people depend solely on farm-ing and marketing of NTFPs in order to generate incomeboost their economic lives improve their nutritional intakesand sustain their livelihood However the socioeconomicnutritional cultural factors are importance values of NTFPsespecially to rural communities that depend on them [1ndash3]and were only brought to limelight in recent timeThe aware-ness of the benefits of NTFPs has been on the increase due tothe roles it play within the microlevel of the economy andhigh potential of the products to contribute to the livelihoodof the people In most part of developing countries employ-ment opportunities from traditional industries are decliningpeople within forest reservation areas look for alternative

sources of income and often turn to the collection of theseproducts from the nearby forest [4]

2 Methodology

The study was conducted in two ecological zones (Rainforestand Derived Savanna) of Ondo State Nigeria Ondo Stateis one of the thirty-six states in Nigeria located within theSouth-Western part of the country The state lies betweenlatitudes 5∘451015840 and 7∘521015840N and longitudes 4∘201015840 and 6∘51015840E

21 Data Collection and Analysis Data for this study werecollected using two sets of structured questionnaires Marketinformation from traders who market the products of thespecies in selected rural and urban markets was collectedwhich indicated the rate of supply demand prices andincome generation on the forest fruit species Farmers withGkola and I gabonensis trees on their farms home gardens orfallow field were selected and the questionnaire administeredto them Total of 60 questionnaires were administeredto farmers while 120 questionnaires were administered totraders This was complemented with focus group discussionas well as participatory observation Data collected from thefield were analysed using descriptive statistical tools such asmean frequency and percentages

22 Linear Statistical Model In addition analysis of variance(ANOVA) arranged in randomized complete block designwas also employed to test for significant difference parameters(eg price etc) from the three market structure (farm gateprice rural market price and urban market price) in the twoecological zones

3 Result

31 Age Distribution of the Respondent

311 Market Assessment The age range of traders of the twoforest fruits tree species in rainforest and derived savannaecosystems is between 21 and 60 years (Table 1) Howeverthere were indications that majority of the traders are middleaged especially those involved in the sale of I gabonensisproducts For example results in Table 1 show that between 80and 93 of traders of I gabonensis in the rainforest ecosystemare between 31 and 50 years old while between 55 and 70of traders ofG kola are between the same age ranges A goodpercentage of traders (45 and 20 in rural and urbanmarkets resp) of G kola in the rainforest ecosystem are over50 years old In the derived savanna ecosystem the traders arebetween the age of 31 and 60 years old except for I gabonensisin urbanmarkets (Table 1) Similar to the results for rainforestmajority of I gabonensis traders are within the 31ndash50 years agebracket Over 45 of the traders ofG kola in both urban andrural markets in the derived savanna are over 50 years old(Table 1)

312 On-Farm Assessment The age range of farmers of theseforest food tree species in rainforest and derived savannaecosystems is between 31 and over 60 years (Figure 1) Theresults in Figure 1 indicated that elderly people are mostlyinvolved in the production of forest fruit species In bothecological zones between 70 and 90 of the farmers are 50years and above (Figure 1)The results indicated that between333 and 484 of the farmers are above 60 years old whichindicated that the farmers of forest fruit species are elderlypeopleThe result also shows that middle-aged people are notfully involved in the production of forest fruit species as onlyabout 42 and 97 of the farmerrsquos are aged between 31 and40 years in the two ecological zones of Ondo State (Figure 1)

32 Gender of the Respondent

321 Market Assessment The result reveals that the femalefolks are more involved in the marketing of the forest foodtree species as shown in Tables 2(a) and 2(b) 105 and 895of traders of Irvingia gabonensis in rural markets in rainforestecosystem are males and females respectively and all traders(100) of the species in urban markets in rainforest arefemale (Table 2(a))The same trendwas observed forGarciniakola trade where about 91 males and 909 females wereobserved to be involved in the sale of the species in ruralmarkets while only femalersquos (100) are involved in the salesof the fruit in urban Results (Table 2(b)) revealed that onlyfemales are involved in marketing all these forest fruits

34 Comparison of Income Generated from Marketing ofForest Fruits Species The results of analysis of varianceindicated that there are significant differences between theaverage annual incomes generated by respondents from thesale of the fruits of the three species within the two ecologicalzones of the study as well as between the variousmarket typesas shown in Tables 4(a) and 4(b)The results showed a signifi-cant difference in income generated from the sale of the fruitsof the species as onemoves from farm gate (on farm) throughrural markets to urban markets The analysis indicated thatincome generated was significantly highest in urbanmarkets in the two ecological zones and it was found to besignificantly higher than income obtained from ruralmarketsand farm gatesThe difference in income generated was morenoticeable in rainforest than in derived savanna ecosystemFor example while average annual income generated at urbanmarkets in the rainforest ecosystem was 119166700($121310) and it was only16666700 ($42200) at farm gatea difference of over 300 (Table 4(a)) The difference inannual income generation at urban markets 112333000($78060) and farm gates 17500000 ($47470) in derivedsavanna ecosystem was about 200 Annual incomegenerated from rural markets in the two ecological zones wassignificantly higher than that of on-farm (farm gate) incomegeneration which is the least and less than110000000Naira($63291 USD) per annum within the two ecological zones(Table 4(a)) The results also show higher-income generationin rainforest ecosystem than derived savanna for the marketanalysis and reverse being the case for on-farm analysiswhich reveals that derived savanna had the higher incomethan the rainforest ecosystem The analysis of variance forthe two forest fruit species within the two ecological zonesis presented in Table 4(b) Irvingia gabonensis generated the

4 Discussion

Most of the respondents (54) are females involved in thesales of forest fruits species indicating that forest fruits mar-keting is a female dominated enterprise and malersquos are themajor collectors and also involved in the production Major-ity of the marketers (72) are within the active labour agerange of 20ndash50 yearsMajority of themarketers used ldquosize andsweetnessrdquo as the standard measure of selling Prices of forestfruits are arrived through bargaining power of the sellers andbuyers as attested to by 70 of the respondents About 54of the respondents claimed that forest fruits are not alwaysavailable throughout the year due to their seasonal natureand perishability The most common method of informingbuyers of forest fruits is through open display as attested to by58 of the respondents The most common strategy of opti-mising forest fruits marketing among respondents is by pro-cessing before sales as attested to by 38 of the respondentsForest fruits marketing is a profitable enterprise with anaverage monthly profit of 11912397 ($12104) per marketerpermonth and in turn can alleviate poverty within the house-hold and this is support of Adebisi 2004 findings [5] Theresults of this study revealed that the production collectionand marketing of I gabonensis and G kola constitute majoreconomic contribution to the livelihood of the people inthe rainforest and derived savanna ecological zones of OndoState The use of these two forest fruits species adds crucial

dimension to a diversified livelihood base of the rural pop-ulace and thereby reducing poverty Thus they act as safetynet particularly when there is a shortfall in agriculturalproduction and thus fill the gap of food shortage and reducemalnutrition

5 Recommendations

Forest fruit species contribute significantly to the peoplersquoseconomy and livelihood Thus priority should be given tothe conservation of the mother trees to ensure sustainableproduction of the fruits while effort should be made towardstheir domestication Currently in the study area especiallyin the rainforest ecosystem domestication of the forest fruitspecies is inadequate It is therefore recommended that forestmanagement strategies and interventions should be designedfor domestication of the forest fruit species in the two ecolog-ical zones to properly address the management and sustain-ability of the resource base of the species

The study was conducted in two ecological zones (Rainforestand Derived Savanna) of Ondo State Nigeria Ondo Stateis one of the thirty-six states in Nigeria located within theSouth-Western part of the country The state lies betweenlatitudes 5∘451015840 and 7∘521015840N and longitudes 4∘201015840 and 6∘51015840E

21 Data Collection and Analysis Data for this study werecollected using two sets of structured questionnaires Marketinformation from traders who market the products of thespecies in selected rural and urban markets was collectedwhich indicated the rate of supply demand prices andincome generation on the forest fruit species Farmers withGkola and I gabonensis trees on their farms home gardens orfallow field were selected and the questionnaire administeredto them Total of 60 questionnaires were administeredto farmers while 120 questionnaires were administered totraders This was complemented with focus group discussionas well as participatory observation Data collected from thefield were analysed using descriptive statistical tools such asmean frequency and percentages

22 Linear Statistical Model In addition analysis of variance(ANOVA) arranged in randomized complete block designwas also employed to test for significant difference parameters(eg price etc) from the three market structure (farm gateprice rural market price and urban market price) in the twoecological zones

The linear statistical model for randomized completeblock design (RCBD) is

3 Result

31 Age Distribution of the Respondent

311 Market Assessment The age range of traders of the twoforest fruits tree species in rainforest and derived savannaecosystems is between 21 and 60 years (Table 1) Howeverthere were indications that majority of the traders are middleaged especially those involved in the sale of I gabonensisproducts For example results in Table 1 show that between 80and 93 of traders of I gabonensis in the rainforest ecosystemare between 31 and 50 years old while between 55 and 70of traders ofG kola are between the same age ranges A goodpercentage of traders (45 and 20 in rural and urbanmarkets resp) of G kola in the rainforest ecosystem are over50 years old In the derived savanna ecosystem the traders arebetween the age of 31 and 60 years old except for I gabonensisin urbanmarkets (Table 1) Similar to the results for rainforestmajority of I gabonensis traders are within the 31ndash50 years agebracket Over 45 of the traders ofG kola in both urban andrural markets in the derived savanna are over 50 years old(Table 1)

312 On-Farm Assessment The age range of farmers of theseforest food tree species in rainforest and derived savannaecosystems is between 31 and over 60 years (Figure 1) Theresults in Figure 1 indicated that elderly people are mostlyinvolved in the production of forest fruit species In bothecological zones between 70 and 90 of the farmers are 50years and above (Figure 1)The results indicated that between333 and 484 of the farmers are above 60 years old whichindicated that the farmers of forest fruit species are elderlypeopleThe result also shows that middle-aged people are notfully involved in the production of forest fruit species as onlyabout 42 and 97 of the farmerrsquos are aged between 31 and40 years in the two ecological zones of Ondo State (Figure 1)

32 Gender of the Respondent

321 Market Assessment The result reveals that the femalefolks are more involved in the marketing of the forest foodtree species as shown in Tables 2(a) and 2(b) 105 and 895of traders of Irvingia gabonensis in rural markets in rainforestecosystem are males and females respectively and all traders(100) of the species in urban markets in rainforest arefemale (Table 2(a))The same trendwas observed forGarciniakola trade where about 91 males and 909 females wereobserved to be involved in the sale of the species in ruralmarkets while only femalersquos (100) are involved in the salesof the fruit in urban Results (Table 2(b)) revealed that onlyfemales are involved in marketing all these forest fruits

Figure 3 Total annual income generated (in Naira) from forestfruits

34 Comparison of Income Generated from Marketing ofForest Fruits Species The results of analysis of varianceindicated that there are significant differences between theaverage annual incomes generated by respondents from thesale of the fruits of the three species within the two ecologicalzones of the study as well as between the variousmarket typesas shown in Tables 4(a) and 4(b)The results showed a signifi-cant difference in income generated from the sale of the fruitsof the species as onemoves from farm gate (on farm) throughrural markets to urban markets The analysis indicated thatincome generated was significantly highest in urbanmarkets in the two ecological zones and it was found to besignificantly higher than income obtained from ruralmarketsand farm gatesThe difference in income generated was morenoticeable in rainforest than in derived savanna ecosystemFor example while average annual income generated at urbanmarkets in the rainforest ecosystem was 119166700($121310) and it was only16666700 ($42200) at farm gatea difference of over 300 (Table 4(a)) The difference inannual income generation at urban markets 112333000($78060) and farm gates 17500000 ($47470) in derivedsavanna ecosystem was about 200 Annual incomegenerated from rural markets in the two ecological zones wassignificantly higher than that of on-farm (farm gate) incomegeneration which is the least and less than110000000Naira($63291 USD) per annum within the two ecological zones(Table 4(a)) The results also show higher-income generationin rainforest ecosystem than derived savanna for the marketanalysis and reverse being the case for on-farm analysiswhich reveals that derived savanna had the higher incomethan the rainforest ecosystem The analysis of variance forthe two forest fruit species within the two ecological zonesis presented in Table 4(b) Irvingia gabonensis generated the

4 Discussion

Most of the respondents (54) are females involved in thesales of forest fruits species indicating that forest fruits mar-keting is a female dominated enterprise and malersquos are themajor collectors and also involved in the production Major-ity of the marketers (72) are within the active labour agerange of 20ndash50 yearsMajority of themarketers used ldquosize andsweetnessrdquo as the standard measure of selling Prices of forestfruits are arrived through bargaining power of the sellers andbuyers as attested to by 70 of the respondents About 54of the respondents claimed that forest fruits are not alwaysavailable throughout the year due to their seasonal natureand perishability The most common method of informingbuyers of forest fruits is through open display as attested to by58 of the respondents The most common strategy of opti-mising forest fruits marketing among respondents is by pro-cessing before sales as attested to by 38 of the respondentsForest fruits marketing is a profitable enterprise with anaverage monthly profit of 11912397 ($12104) per marketerpermonth and in turn can alleviate poverty within the house-hold and this is support of Adebisi 2004 findings [5] Theresults of this study revealed that the production collectionand marketing of I gabonensis and G kola constitute majoreconomic contribution to the livelihood of the people inthe rainforest and derived savanna ecological zones of OndoState The use of these two forest fruits species adds crucial

dimension to a diversified livelihood base of the rural pop-ulace and thereby reducing poverty Thus they act as safetynet particularly when there is a shortfall in agriculturalproduction and thus fill the gap of food shortage and reducemalnutrition

5 Recommendations

Forest fruit species contribute significantly to the peoplersquoseconomy and livelihood Thus priority should be given tothe conservation of the mother trees to ensure sustainableproduction of the fruits while effort should be made towardstheir domestication Currently in the study area especiallyin the rainforest ecosystem domestication of the forest fruitspecies is inadequate It is therefore recommended that forestmanagement strategies and interventions should be designedfor domestication of the forest fruit species in the two ecolog-ical zones to properly address the management and sustain-ability of the resource base of the species

34 Comparison of Income Generated from Marketing ofForest Fruits Species The results of analysis of varianceindicated that there are significant differences between theaverage annual incomes generated by respondents from thesale of the fruits of the three species within the two ecologicalzones of the study as well as between the variousmarket typesas shown in Tables 4(a) and 4(b)The results showed a signifi-cant difference in income generated from the sale of the fruitsof the species as onemoves from farm gate (on farm) throughrural markets to urban markets The analysis indicated thatincome generated was significantly highest in urbanmarkets in the two ecological zones and it was found to besignificantly higher than income obtained from ruralmarketsand farm gatesThe difference in income generated was morenoticeable in rainforest than in derived savanna ecosystemFor example while average annual income generated at urbanmarkets in the rainforest ecosystem was 119166700($121310) and it was only16666700 ($42200) at farm gatea difference of over 300 (Table 4(a)) The difference inannual income generation at urban markets 112333000($78060) and farm gates 17500000 ($47470) in derivedsavanna ecosystem was about 200 Annual incomegenerated from rural markets in the two ecological zones wassignificantly higher than that of on-farm (farm gate) incomegeneration which is the least and less than110000000Naira($63291 USD) per annum within the two ecological zones(Table 4(a)) The results also show higher-income generationin rainforest ecosystem than derived savanna for the marketanalysis and reverse being the case for on-farm analysiswhich reveals that derived savanna had the higher incomethan the rainforest ecosystem The analysis of variance forthe two forest fruit species within the two ecological zonesis presented in Table 4(b) Irvingia gabonensis generated the

4 Discussion

Most of the respondents (54) are females involved in thesales of forest fruits species indicating that forest fruits mar-keting is a female dominated enterprise and malersquos are themajor collectors and also involved in the production Major-ity of the marketers (72) are within the active labour agerange of 20ndash50 yearsMajority of themarketers used ldquosize andsweetnessrdquo as the standard measure of selling Prices of forestfruits are arrived through bargaining power of the sellers andbuyers as attested to by 70 of the respondents About 54of the respondents claimed that forest fruits are not alwaysavailable throughout the year due to their seasonal natureand perishability The most common method of informingbuyers of forest fruits is through open display as attested to by58 of the respondents The most common strategy of opti-mising forest fruits marketing among respondents is by pro-cessing before sales as attested to by 38 of the respondentsForest fruits marketing is a profitable enterprise with anaverage monthly profit of 11912397 ($12104) per marketerpermonth and in turn can alleviate poverty within the house-hold and this is support of Adebisi 2004 findings [5] Theresults of this study revealed that the production collectionand marketing of I gabonensis and G kola constitute majoreconomic contribution to the livelihood of the people inthe rainforest and derived savanna ecological zones of OndoState The use of these two forest fruits species adds crucial

dimension to a diversified livelihood base of the rural pop-ulace and thereby reducing poverty Thus they act as safetynet particularly when there is a shortfall in agriculturalproduction and thus fill the gap of food shortage and reducemalnutrition

5 Recommendations

Forest fruit species contribute significantly to the peoplersquoseconomy and livelihood Thus priority should be given tothe conservation of the mother trees to ensure sustainableproduction of the fruits while effort should be made towardstheir domestication Currently in the study area especiallyin the rainforest ecosystem domestication of the forest fruitspecies is inadequate It is therefore recommended that forestmanagement strategies and interventions should be designedfor domestication of the forest fruit species in the two ecolog-ical zones to properly address the management and sustain-ability of the resource base of the species
