La lutte contre les glossines dans la zone agropastorale de Yalé (Burkina Faso): résultats d'enquêtes socioéconomiques

Abstract: Tsetse Control in the Yalé Agropastoral Zone (Burkina Faso): Results of Socio-economic Surveys. The study examines the impact of a tsetse campaign (1994-1997) in southern Burkina Faso. In the absence of health - productivity monitoring, data were collected in cross sectional surveys to generate quantitative estimates of relevant productivity traits for cattle. The results indicate the following: 25% increase in herd size; reduction in mortality from 63.1% to 7.1% and increase in live births of 57.6%. Milk yield rose from 0.2 to 2.2 litres/cow/day in the dry season. These results show the impacts trypanosomosis control can have on zebu cattle exposed to a high tsetse challenge. The study underscores the importance of well designed surveys as a cost-effective way of generating estimates of productivity impacts. These estimates can be a useful alternative to subjective assessments in modelling the economic benefits.
Farmers' willingness to contribute to tsetse and trypanosomosis control in West Africa: the case of northern C te d'Ivoire

Abstract: The study was conducted in 1997 on a sample of 224 livestock farmers in four clusters representing the diversity in production systems of northern C te d'Ivoire, in order to evaluate the willingness of beneficiaries to pay for tsetse control using traps and targets. Results of a contingent valuation survey indicate that 94% of respondents are willing to contribute money, 86% are willing to contribute labor and 81% are willing to contribute in both money and labor. Farmers pledged an average contribution of 236 CFA francs (0.47 USD) per head of cattle per year and eight days per month per farm family. Significant differences were noted in the level of resource contributions according to the production system and breed composition of herds. Estimates from a recursive Tobit model of factors affecting willingness to contribute labor reveal the following as significant factors: knowledge of the tsetse fly and trypanosomosis symptoms, location, years of experience as collective herd manager and the practice of transhumance. There are few factors significantly associated with willingness to contribute money. Thus, organizing a scheme for resources contribution to sustain the benefits of tsetse control should take into account the differences in production systems, farm location and breed composition of herds.
Resources endowment, income distribution and needs for techno-logies among peri-urban smallholders in the Gambia

Biotechnologie, Agronomie, Société et Environnement , 2006,
Abstract: One reason of the modest adoption of improved technologies by smallholder farmers is that the majority of them are resource constrained. Structural constraints at the households level and institutional weaknesses have often prevented most of the farmers from joining the economic development process. This study analyses the production resources in relation with the income and the needs for improved technologies of the peri-urban farm households in The Gambia. The results are compelling. The majority of the production resources are owned by small fraction of the smallholders. As a consequence, their income is higher and mostly derived from agriculture, while the poor-resource households rely on a relatively wide variety of activities to compensate their low income. The poor-resource households have also the greatest need for improved technologies, although many would also need some kind of subsidies to uptake them. There is a clear need for more agricultural research, expertise and policy-making to transcend the traditional global understanding of smallholder farmers, and consider their heterogeneity in terms of production resources.
Facteurs affectant l'adoption des cultures fourragères dans les élevages laitiers péri-urbains de Bobo-Dioulasso, Burkina Faso

Abstract: Factors Affecting the Adoption of Fodder Crops in Bobo-Dioulasso (Burkina Faso) Peri-urban Dairy Farms. The study aims to identify the factors affecting the adoption of annual (Dolichos lablab) and perennial (Andropogon gayanus, Brachiaria ruziziensis and Panicum maximum) fodder crops on peri-urban dairy farms of Bobo-Dioulasso (Burkina Faso). The results of a logistic regression model (LIMDEP ) revealed a number of significant factors (P< 0.05) associated with five main constraints preventing wider use of fodder crops in cultural practices. These include increased labor demand at peak cropping season, land tenure rights, field protection, availability of fodder seeds, and low productivity gain associated with the introduction of fodder crops. Fodder crops adoption rates would be higher with the adaptation of the technology to local conditions and increased emphasis on farmers' training and sensitization campaigns.
Evaluating Farmers` Willingness to Adopt Integrated Packages for Trypanosomosis Control in The Gambia: Application of Demand Revealing Mechanisms

Pakistan Journal of Social Sciences , 2012,
Abstract: Community participation in tsetse and trypanosomes control constitutes a focal point in most donors-sponsored initiatives. This shift in the approach to eradicating trypanosomosis calls for a close look at the underlying incentive structure for individuals in a community to cooperate in agreements to provide various control methods. This study applies a demand revealing mechanism to assess factors influencing decision-making of smallholder farmers with regards to tsetse and/or trypanosomes control. The results show that farmer`s resources and perception about the efficacy of the traponocidal drugs are important factors. Farmers are also more willing to invest in vector control techniques than parasite control, although the latter is currently widely used. They are also more willing to contribute within a community-based organization than individually. The paper concludes on the potentials of the demand revealing mechanism over the contingent valuation techniques when assessing semi-public goods with market price.
Socio-Economic Analysis of Tsetse Control Experiments in The Central River Division, The Gambia: Impacts and Farmers` Perceptions

Pakistan Journal of Social Sciences , 2012,
Abstract: Mulumba Kamuanga, Jacques Somda, William F. Snow and Constance I. Mugalla Tsetse control with topical applications of pyrethroid insecticide to cattle in the Central River Division (CRD) of The Gambia was successful in reducing trypanosomosis in village N`Dama cattle. The experiments that included 700 cattle in 5 villages (1994-95, grazing 90 km2) treated with deltamethrin spray twice monthly; and 2300 cattle in 15 villages (1996-97, grazing 265 km2) treated with pour-on, were conducted with knapsack sprayers. Experiment results and follow up socio-economic surveys helped to estimate the impacts and benefits of the intervention and ascertain farmers` perceptions of the changes in productivity. Reproductive performance traits were assessed from data collected in health and productivity monitoring studies. The intervention resulted in a reduction of Glossina m. submorsitans numbers of 17% (spray) and 33% (pour-on); the challenge fell by 68% compared with 11% in the non-intervention area over the first period. The use of trypanocides (80% of the households) was not affected by the intervention, although the numbers of users among trial participants decreased over the 1994-97 period. Productivity estimates indicated 5.2 kg/animal in weight gain for treated animals and 60.2% increase in calving rates, implying a positive impact on reproductive performance. The trend in milk production failed to support the hypothesis of increased yield as a benefit of tsetse control. The costs of control for an average farmer raising 60 cattle were compared to benefits in a partial budget approach, pointing to an average net benefit per farmer of US$563 for spray users and US$454 in pour-on, with marginal rates of returns of 285% and 235%, respectively. This translates into benefits per TLU of about US$11 for spray and $9 for pour-on. The impacts of trypanosomosis on the N`Dama breeds was moderated by their tolerance of the disease and both financial and economic benefits of the intervention were less striking than in a situation with tyrpanosusceptible breeds. Farmers perceived advantages and disadvantages in using sprays and pour-on. The sustainability of the benefits remained an important aspect and a condition of technology adoption, particularly with the acquisition and maintenance of the knapsack sprayers, timely delivery of the insecticides and reliability of delivery services.
