Role of non-timber forest products in the economy of peripheral communities of knuckles national wilderness area of Sri Lanka: A farming systems approach

The Knuckles range of forests has been identified as a unique biological resource in Sri Lanka with much biodiversity. It is also important as a watershed which feeds the Mahaweli reservoir system. Having considered the present hazardous land-use practices such as cardamum production and shifting cultivation, the Knuckles range has been declared a national wilderness area. The Forest Department is in the process of preparing the management plan for the area. There are about 48 villages in the vicinity of the forest. This study attempts to estimate the composition of income in the peripheral communities, ticularly the extraction of non-timber forest products (NTFP) from this range of forests. Data were collected using structured questionnaires from 60 households in three villages in the vicinity of the forest. The rural economy is described using a farming systems approach and the net income contributed by each activity in the farming system was estimated. Results show that nine components of the farming system use resources from the village and the forest, with at least 47 plant species used by the villagers for different purposes. Cardamum production and shifting cultivation contribute significantly to the total income of the household, but the majority of households in the study depend upon forest resources to supply some portion of their income. Nevertheless, the monetary value of the annual income generated by NTFP is much lower than income from either cardamum production or shifting cultivation. If cardamum production and shifting cultivation are to be restricted under the conservation program, there could be additional pressure put on NTFP. Therefore, we suggest a study of the natural regen-eration capacity of selected NTFP; such information should be used in finalizing the management plan in the Knuckles range of forests.     

Relocating plants from swidden fallows to gardens in Southwestern China

As upland farmers in Southeast Asia change from shifting cultivation to permanent agriculture and lose access to swidden-fallow forests and their resources, they are introducing economically important forest and fallow plants into their house gardens. We describe this process in Daka, a village of Hani ethnicity in Yunnan Province, China. Daka smallholders collect both seeds and seedlings from fallow forests and transfer the plants to house gardens, initiating the transformation of wild species to a cultivated or semi-domesticated one. Two kinds of species are commonly transferred from swidden fallows to house gardens. Some are particularly rare, others are plants in great demand. Between 1998 and 2000 Daka households earned an average of US$68.20 annually from the products of fallow forests. We also found that villagers harvest and use 76 plant species from fallow forests and 126 species from house gardens. Twenty-two species found in house gardens that had been transferred from fallow forests. Households vary widely in the frequency with which they engage in this pattern. We believe that local knowledge of these practices is a potentially important resource in the development of other areas of smallholder farming.     

Variation in Indigenous Forest Resource Use in Central Guyana

Sustainable forest conservation strategies should be based on local as well as landscape-scale forest resource use data. Using ecological and sociological techniques, we test the hypotheses that (1) forest resource use differs between ethnic and socioeconomic indigenous groups and (2) that this difference results in differing spatial patterns of resource use, with implications for forest diversity and for conservation planning. In the North Rupununi Guyana, three adjacent indigenous communities (differing in their indigenous/immigrant balance) were recorded using 73 animal and 164 plant species (plus several unidentified ethno-species). Farm sites formed important foci for most forest based activities and ex-farm sites supported similar floristic diversity to surrounding forest. Resource usage differences between communities could be attributed to socio-cultural drivers, e.g. mammal meat consumption and the use of the fruits from the palm tree A. maripa were higher in more traditional households. When extracting household construction timber, lower income groups created small scattered felling sites akin to tree fall gaps whereas higher income groups created larger gaps. Lower income (indigenous) households tended to clear larger but more contained sites for farming while mixed or non-Amerindian household tended to clear smaller but more widely dispersed farm sites. These variations resulted in different patterns of forest disturbance originating from agriculture and timber extraction.     

Distribution of Agrobiodiversity in Home Gardens along the Corrientes River,Peruvian Amazon

Distribution of Agrobiodiversity in Home Gardens along the Corrientes River, Peruvian Amazon. This paper examines crop species diversity in home gardens of traditional communities along a remote tributary in northeastern Peru. A large-scale survey was conducted of 300 gardens in 15 villages along a 150 km reach of the Corrientes River. Study villages vary notably in community size, ethnicity of residents (Achuar, Urarina, mestizo), and proximity to the regional town (Trompeteros) as well as to oil wells. Gardens were inventoried and interviews conducted with garden tenders to provide data on socioeconomic characteristics of the household and contextual conditions. Multiple regression analyses identified the determinants of species diversity. Results indicate high crop diversity—the highest yet reported for sites in the Amazon basin—particularly among the Achuar people. Garden species diversity is greatest in larger villages and, surprisingly, in those villages located nearer to the oil company. Within villages, households with larger land holdings (and gardens), more in-house labor, and garden tenders who are older and female tend to have more diverse gardens. A small number of households (15/300) were found to hold exceptional diversity, often older and land-wealthier households located on the outskirts of villages. These farmers held, on average, three times the number of species as a typical village garden and 60% of all species encountered in the study.     

Homegardens in Smallholder Farming Systems: Examples From Bangladesh

Homegardens are integral part of rural households in Bangladesh. The present study examines some physical, biological, and socioeconomic characteristics of 32 homegardens randomly selected from four villages representing different agro-ecological conditions, variable population densities, and market opportunities. The study results suggest that large numbers of plant and animal species occupy homegardens, and their composition and intensity of cultivation vary directly with the household physiologic density and access to urban markets, and inversely with environmental constraints to agriculture. Homegardens form the activity space for household women and children, who perform most homegarden farming tasks. Uses of home generated inputs at no or low cost make homegardens economically more efficient and sustainable compared to non-homegarden rice farming. In the context of the intensive subsistence agriculture patterns that dominate Bangladesh, homegardens contribute significantly to smallholder household income.

Keeping the Home Fires Burning: The Changed Nature of Householding in the Kofyar Homeland

In the early 1960s, Robert Netting described households in the Kofyar homeland in Nigeria and explained their size, composition, and other characteristics as adjustments to agrarian ecology. Household changes attending movement to a frontier were analyzed in the same framework. By the 1980s, the economic rationale for homeland farming had all but disappeared, and some villages seemed on the verge of abandonment. Yet deliberate strategies for preserving homeland settlements had prevented abandonment. The demographic characteristics and household composition in the homeland now provide a window into a wholly different set of processes than what Netting described 30 years ago. Home settlement is kept viable as a facility to support ethnic identity and to attract government resources. Beneath superficial similarities are profound changes in the nature of the household and factors shaping it, reflecting the changed rationale for keeping the home fires burning.     

Effects of Socioeconomic Conditions on Multiple Uses of Swamp Forests in Central Brazil

Local communities in central Brazil harvest buriti palm (Mauritia flexuosa) fruit from swamp forests as well as using them for agriculture and cattle and pig farming. This study describes the intensity of forest use by buriti fruit harvesters and identifies how their socioeconomic conditions influence resource use. We visited 75 swamp forests where buriti fruits are harvested and interviewed the head of the nearest household. Agriculture was practiced in 72?% of forests and cattle farming in 52?%. For almost half (48?%) of households agriculture and buriti fruit harvest were the main sources income. Forests resources were equally important to all socioeconomic classes, even richer farmers. The intensity of fruit harvest did not differ between collective and private use regimes of forests. Market access was a limitation to fruit harvest intensity. The high intensity of swamp forest use suggests that their conservation will require change to current management practices.     

Rice and Remittances: Crop Intensification Versus Labour Migration in Southern Laos

Despite being a low-income, agriculture-based country with a subsistence orientation, Laos is in the early stages of a major economic transformation whereby rural households have been experiencing rapid change in their farming and livelihood systems. Some households have begun to engage in semi-commercial farming while others have adopted labour-oriented or migration-oriented livelihood strategies. This paper explores how rural households in six villages in the lowlands of Champasak Province in southern Laos make a living. These villages vary in their access to irrigation and to markets. Nevertheless, in all villages, long-term migration of younger household members to neighbouring Thailand has come to play a large role in household livelihood strategies. In some cases this is necessary to meet the household’s consumption requirements; in most, it is part of a diversified strategy in which rice farming still plays a significant role, though still largely for subsistence. The paper examines some of the issues involved in attempting to promote intensive, market-oriented rice farming in a context of an emerging on-farm labour shortage combined with an increasing flow of remittances from migrant family members.     

Cultivated plant species diversity in home gardens of an Amazonian peasant village in Northeastern Peru

Research on agrobiodiversity points to the importance of home gardens in situ conservation, yet few studies to date explicate the origins and dynamics of plant species diversity. In this paper, we examine inter-household variations in cultivated plant species diversity among house gardens in a traditional peasant community, near Iquitos, Peru. In-depth household interviews (n = 24) and garden/field surveys reveal that home gardens are clearly the site of highest plant diversity in farmers’ field portfolios, and that substantial differences exist in garden composition, plant diversity, and the sources of garden planting material across households. Statistical analyses indicate that home garden diversity is related strongly to specific garden characteristics, household socioeconomic features, and access to planting material including seeds, cuttings, and suckers. The role and implications of differential access to planting material in the development and maintenance of crop species diversity is signaled as an important theme for future study in economic botany.     

Nontimber forest product gathering in Ritigala forest (Sri Lanka): Household strategies and community differentiation

Sri Lanka has a long tradition of forest product use. The relationship of people with a dry zone forest was studied using a sample of 48 households in two villages that varied in distance to the forest and access to the market. All households interviewed collected subsistence forest products and a majority of them also collected commercial products. The daily peak-season income from commercial gathering was 4.5 to 7.7 times the daily labor wage. There is a strong gender specialization, with commercial gathering dominated by men whereas subsistence gathering is almost exclusively the task of women. The average forest-derived household income in the village closer to the forest and with better market access was nearly double that of the other village. Family size as a proxy of labor availability was the main discriminating factor between those households who did and those who did not gather commercial products. A small inverse relationship between forest gathering and size of household agricultural land (particularly paddy rice) was observed. No clear relationship was found between total household income and forest derived income, contradicting the view that commercial forest gathering is an exclusive activity of the poorest households.     

A predictive model to locate ancient forests in the Cross Timbers of Osage County, Oklahoma

The Cross Timbers are a mosaic of upland deciduous forest, savanna, and glade that typifies the broad ecotone between the eastern deciduous forest and the grasslands of the southern Great Plains. The pre-settlement Cross Timbers may have covered some 7,909,700 ha from central Texas, across Oklahama into eastern Kansas, and today may represent the least disturbed forest ecosystem of comparable size still left in the eastern United States. Extensive tree-ring research indicates that ancient forests dominated by 200 to 400 year old post-oaks ( Quercus stellata Wang) survive throughout the Cross Timbers, particularly in Oklahoma. These ancient forests persist largely because the Cross Timbers formation is non-commercial for timber production, and has not experienced large-scale industrial logging. Because ancient forest relics are often found on stressful non-commercial sites in the Cross Timbers and elsewhere, it is possible to design predictive models to locate the specific terrain where undisturbed forests are likely to survive. A predictive model for southern Osage County, Oklahoma, was developed based on the steep, infertile soils of the Niotaze-Darnell complex. We tested the model with field inspection and tree-ring analysis of fifty randomly selected belt transects, and 74% of the sampled terrain is still old-growth Cross Timbers woodland. This translates into 8200 ha of ancient Cross Timbers on this single site type in southern Osage County. The abundance of ancient forest in the Cross Timbers is not widely appreciated. However, large contiguous tracts of ancient Cross Timbers up to 700 ha were identified with this predictive model, strongly supporting inferences concerning the relatively undisturbed nature of this ecosystem.     

Cross-Location Analysis of the Impact of Household Socioeconomic Status on Participation in Urban and Peri-Urban Agriculture in West Africa

This study explores the relation between household socioeconomic status (SES) and participation in urban and periurban agriculture (UPA) in three West African cities. We used a structured questionnaire to survey 700 randomly selected households: 250 in Kano, Nigeria, 250 in Bobo Dioulasso, Burkina Faso, and 200 in Sikasso, Mali. Multiple correspondence analysis was applied on household asset variables to create an index of assets which was used as a proxy for household SES. The results showed no significant differences in households’ rate of participation in UPA across socioeconomic groups. Participation in UPA was rather significantly (P < 0.001) and positively related to household size. Interestingly, the analysis revealed that field crop cultivation and gardening were more common among households in the low and medium SES groups while those in the high SES group were more likely to keep livestock.     

Bearing the Burden: Portage Labor as an Adaptive Response to Predictable Food Deficits in Eastern Nepal

Wage work such as portage labor is one of several adaptive strategies by which rural households in Nepal supplement their subsistence agriculture. This study, conducted in the hills of eastern Nepal in 1997, surveyed the landholdings and household subsistence base of 50 commercial porters hired to transport loads from Jiri to various destinations in Solu Khumbu. A major goal was to test the hypothesis that porter households tend to have smaller landholdings than the average household in this region. An unexpected result was that porter households in this study owned nearly as much arable land (1.07 ha) as the mean of 1.15 ha for all hill families in eastern Nepal. Household grain sufficiency correlated significantly (P < 0.01) with farm size (r = 0.53). The majority of the porters lived in villages located at either the origin or the endpoint of their portage work. The study also examined several variables that might explain why portage labor is a full-time occupation for some Nepalis, but a part-time “casual” occupation for others. The most significant difference between households of full-time and part-time porters was the availability of workers at home for managing the household’s land and livestock resources. Households of full-time porters were better able to spare a family member for full-time wage labor because they had significantly more adult workers of either gender (P < 0.05) than households of part-time porters. Full-time and part-time porter households did not differ significantly with regard to family size, land ownership, or number of food-deficit months.     

Exploring Consumer Perceptions and Economic Burden of Onchocerciasis on Households in Enugu State,South-East Nigeria

Introduction

Onchocerciasis or river blindness constitutes a major burden to households especially in resource-poor settings, causing a significant reduction in household productivity. There has been renewed interest from policy makers to reduce the burden of Neglected Tropical Diseases (NTDs) such as onchocerciasis on individuals and households. This paper provides new information on the patient’s perceptions of onchocerciasis and its economic burden on households in South-eastern Nigeria. The information will be useful to health providers and policy makers for evidence-informed resource allocation decisions.

Methods

Information was generated from a cross-sectional household survey conducted in Achi community, Oji River Local Government Area (LGA) of Enugu State, Southeast Nigeria. A pre-tested interviewer-administered questionnaire was used to collect data. A total of 747 households were visited randomly and data were collected using pre-tested interviewer administered questionnaire from 370 respondents. The respondents’ knowledge of the cause of symptoms of the disease, costs incurred for seeking treatment and productivity losses were elicited. Data were analyzed using tabulations and inferential statistics. A socio-economic status (SES) index was used to disaggregate some key variables by SES quintiles for equity analysis.

Results

Many people had more than one type of manifestation of onchocerciasis. However, more than half of the respondents (57%) had no knowledge of the cause of their symptoms. Male respondents had significantly more knowledge of the cause of symptoms than females (P = 0.04) but knowledge did not differ across SES (P = 0.82). The average monthly treatment cost per respondent was US$ 14.0. Drug cost (US$10) made up about 72% of total treatment cost. The per capita productivity loss among patients was US$16 and it was higher in the poorest (Q1) (US$20) and the third SES quintiles (Q3) (US$21). The average monthly productivity loss among caregivers was US$3.5.

Conclusion

Onchocerciasis still constitutes considerable economic burden on patients due to the high cost of treatment and productivity loss. Prioritizing domestic resource allocation for the treatment of onchocerciasis is important for significant and sustained reduction in the burden of the disease. In addition, focused health promotion interventions such as health education campaigns should be scaled up in onchocerciasis-endemic communities.     

Community-based natural resource use and management of Bigodi Wetland Sanctuary,Uganda, for livelihood benefits

Conservation and sustainable management of wetlands requires participation of local stakeholders, including communities. The Bigodi Wetland is unusual because it is situated in a common property landscape but the local community has been running a successful community-based natural resource management programme (CBNRM) for the wetland for over a decade. Whilst external visitors to the wetland provide ecotourism revenues we sought to quantify community benefits through the use of wetland goods such as firewood, plant fibres, and the like, and costs associated with wild animals damaging farming activities. We interviewed 68 households living close to the wetland and valued their cash and non-cash incomes from farming and collection of non-timber forest products (NTFPs) and water. The majority of households collected a wide variety of plant and fish resources and water from the wetland for household use and livestock. Overall, 53% of total household cash and non-cash income was from collected products, mostly the wetland, 28% from arable agriculture, 12% from livestock and 7% from employment and cash transfers. Female-headed households had lower incomes than male-headed ones, and with a greater reliance on NTFPs. Annual losses due to wildlife damage were estimated at 4.2% of total gross income. Most respondents felt that the wetland was important for their livelihoods, with more than 80% identifying health, education, craft materials and firewood as key benefits. Ninety-five percent felt that the wetland was in a good condition and that most residents observed the agreed CBNRM rules regarding use of the wetland. This study confirms the success of the locally run CBNRM processes underlying the significant role that the wetland plays in local livelihoods.     

Ethnobotanical Knowledge and Crop Diversity in Swidden Fields: A Study in a Native Amazonian Society

Crop diversity protects food consumption in poor households within developing nations. Here we estimate the association between crop diversity on swidden fields and ethnobotanical knowledge. We conducted research among 215 male household heads from a native Amazonian society. Using multivariate regressions, we found higher crop diversity among households that depend on agricultural production for household consumption. We also found a statistically significant and positive, but low, association between the ethnobotanical knowledge of the male household head and crop diversity. Doubling the stock of ethnobotanical knowledge of the male household head is associated with a 9% increase in the number of crops sown by a household. The association remained after we controlled for the household level of market exposure, but vanished after we controlled for the social capital of the male household head. Future research should compare the association between ethnobotanical knowledge and crop diversity across different agricultural systems (i.e., home gardens, fallow fields).     

Changing Realities—Perspectives on Balinese Rice Cultivation

This paper discusses issues of agrarian change in south-central Bali. The proximity to urban areas, especially the tourist centers along the southern coast, provides many off-farm employment opportunities for small-scale farming households. Although rice farming continues, for many households it has become a side business. The flexible nature of rice farming in terms of labor input and available casual off-farm work allows farming households to allocate their available labor to a variety of on-farm and off-farm income generating activities. The subak which unites farmers in the irrigation and cultivation of the rice crop plays an important role in supporting this flexibility. Still, the future of rice farming and the organization behind it looks rather dim with a younger generation unwilling to work in the “mud” and little appreciation of the many benefits the subak provides not only to the farming but to the wider community.     

Is Poverty Driving Borana Herders in Southern Ethiopia to Crop Cultivation?

This study addresses whether or not crop cultivation by Borana herders in southern Ethiopia is motivated by poverty since 80% of the households belong to poor wealth classes (i.e., poor, very poor and destitute). Yet our findings showed little evidence that Borana communities have become self-sufficient in grain production. Compared to wealthy households, poor households generally cultivated the least land and sampled households, producing yields only 31% of the Ethiopian national average. Grain per capita met only 26% of the annual requirement per person, equivalent to three to four months of self-sufficiency per household. The livelihood response model (LRM) developed for testing the relationship between extent of croplands and household wealth showed that poverty alone cannot be motivating herders to cultivate crops. Factors such as shortage of labor, lack of sufficient traction animals, and unreliable rainfall also need to be considered. Crop cultivation has not enabled self-sufficiency, but it has resulted in fragmented grazing lands. Future policies address changes in land use, including improving soil fertility through manure-nutrient transfers, by promoting better integration of crop cultivation and pastoralism. Research is needed to (a) understand household time allocation between crop cultivation and livestock management, (b) improve the LRM by considering temporal variability in the wealth of households and extent of cultivated lands, and (c) understand the role of poverty in motivating the adoption of alternative livelihood coping strategies.     

Household factors influencing participation in bird feeding activity: a national scale analysis

Ameliorating pressures on the ecological condition of the wider landscape outside of protected areas is a key focus of conservation initiatives in the developed world. In highly urbanized nations, domestic gardens can play a significant role in maintaining biodiversity and facilitating human-wildlife interactions, which benefit personal and societal health and well-being. The extent to which sociodemographic and socioeconomic factors are associated with engagement in wildlife gardening activities remain largely unresolved. Using two household-level survey datasets gathered from across Britain, we determine whether and how the socioeconomic background of a household influences participation in food provision for wild birds, the most popular and widespread form of human-wildlife interaction. A majority of households feed birds (64% across rural and urban areas in England, and 53% within five British study cities). House type, household size and the age of the head of the household were all important predictors of bird feeding, whereas gross annual household income, the occupation of the head of the household, and whether the house is owned or rented were not. In both surveys, the prevalence of bird feeding rose as house type became more detached and as the age of the head of the household increased. A clear, consistent pattern between households of varying size was less evident. When regularity of food provision was examined in the study cities, just 29% of households provided food at least once a week. The proportion of households regularly feeding birds was positively related to the age of the head of the household, but declined with gross annual income. As concerns grow about the lack of engagement between people and the natural environment, such findings are important if conservation organizations are successfully to promote public participation in wildlife gardening specifically and environmentally beneficial behaviour in society more generally.
