In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. This study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: The results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. Seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. This organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. The health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: To reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.展开更多

According to static game model, it re-vealed that the reason for low compliance rate of "company + farmer" model was the existence of market risk, namely, the fluctuation of market price, and the stable market price in contracts was actualy a kind of interval, instead of a specific value. Furthermore, the effect of default penalty, market transaction cost and time prefer-ence cost on the stability of contract was studied. The results showed that default penalty, market transaction cost and time preference cost had positive influence on the price interval range of a contract.展开更多

The analysis consists of three major steps, which is based on the spatial unit of township. Firstly, the spatial extent and characteristics of flood risk areas were determined using a digital elevation model (DEM) derived from the 1:50,000 topographic map. Secondly, for each of the township, six indices indicating the economic activities of local farmers were calculated. These indices are: rural population proportion, cultivated land proportion, GDP per unit area, employment proportion of primary industry, net rural income per capita and agricultural income proportion. These six indices were then normalized and used for later vulnerability assessment. Thirdly, the normalized indices (as GIS data layers) were overlaid with the flood risk areas to produce the risk coefficient for each township and to calculate the overall vulnerability for each township. The analysis results show that in the PLR there are high flood risk areas where the farmers' livings are seriously influenced or threatened. About 55.56% of the total 180 townships in the flood risk areas have a high degree of flood vulnerability. The townships under flood risk are mainly distributed in the areas around the Poyang Lake and the areas along the "five rivers".展开更多

Farmers’ knowledge and awareness of the proper usage of agrochemicals are critical for mitigating the negative effects on human health. This cross-sectional study was aimed at assessing the usage knowledge, risk awareness of toxicological and chemical classes, proper handling and use practices for agrochemicals homologated for use in vegetable farming, and the occurrence of health-related symptoms as a result of exposure among these farmers. The study included 93 vegetable growers from agricultural hotspot towns in Fako, southwest Cameroon. The field study, ran from November 2021 to December 2023, using a questionnaire to collect information on farmers demographic, and their knowledge of pesticide classes, and the related risk of associated with the handling of agrochemicals. Results show that all vegetable farmers, particularly those engaged in agribusiness, employ pesticide inputs to maximize production. Six pesticides, two fertilizer types, and one unknown substance were identified. While 23 active compounds were found, the most utilized were abamectin, emamectin (10.46%), dimethoate (9.30%,) and ethoprophos (8.13%). Two active chemicals, dimethoate and methalaxyl, are illegal yet remain in circulation. Toxicological classes I and II, with the greatest harmful effect on human health, were the most commonly utilized (64.27%). Thirty-nine percent of farmers never use personal protection equipment when working with agrochemicals, demonstrating a significant gap in knowledge and awareness of agrochemicals and their various applications and handling procedures in the field. The government should implement an intensive specialized educational program for on-field farmers with incentives in order to promote sustainable agriculture methods that ensure environmental and human safety.展开更多

On the basis of these, static and dynamic models are established to analyze the prevention mechanism for default risk in small amount credit. It is concluded that we must establish a restriction mechanism during operation of small amount credit as long as three values increase, namely, N (potential loss of bad credit record due to farmers' default), Q (probability of successful recovery by small amount credit institution), and S (cost of small amount credit institution punishing farmers after successful recovery). Finally, following countermeasures and suggestions are put forward: perfect laws and regulations and credit reward and punishment mechanism for risk management of small amount credit; bring into play proper function of loan officer in small amount credit practice; widely promote rural "Group Credit Union" system.展开更多

The specific objectives were to describe the socio-economic characteristics of cassava farmers in the area and to examine the farmers’ climate change risk perception through examining their perception of the various sources of climate change risk. Multi-stage sampling technique was used to select one hundred and sixty (160) respondents who were selected from 40 communities and 8 Local Government Areas from across the four Agricultural Zones of the state. Data were obtained through the administration of structured questionnaire to the respondents. Data collected were analyzed using descriptive statistics, weighted mean obtained from Likert scale, and Tobit regression model. The results of the socioeconomic characteristics of farmers showed that majority of the farmers had formal education and only 15.19% had no formal education, 56.74% of the farmers had 11 years of farming experience. The farmers’ risk perception showed that the most important risk factors perceived by cassava farmers in their farm were flooding/erosion, increased frequency and intensity of rainfall and incidence of pest and diseases. The factors that influenced the farmers’ level of risk perception included age, level of education, access to extension agents and access to climate change information. Based on the findings of cassava farmers’ level of risk perception, it was inferred that the farmers have reasonable perception of climate change risk. It was therefore recommended from the findings of this research that there is need for effective and functional extension services and provision of enabling environment and policies that will help boost the socio-economic welfare of farmers as this will significantly help in the management of climate change risk in the study area.展开更多

Th...The article assesses the determinants of farmers' decisions to participate in organic farming, eliciting farmers risk preferences and empirically analysing farmer's sources of risk and risk management strategies. The ordered probit results indicate that older farmers, who are less risk averse and reside in the sub-ward Ogagwini, Ezigani and Hwayi were more likely to be certified organic. Similarly, the propensity to adopt organic farming is positively correlated to household size, livestock ownership, asset base and tenure security. At higher pay-offs, farmers were intermediate to moderately risk-averse, with little variation according to personal characteristics. In general, price, production and financial risks were perceived as important sources of risk. Seven principal components, explaining 66.13% of the variation were extracted. Socio-economic factors having a significant effect on the various sources of risk were age, gender, education, location, information access and risk taking ability. The dimensions of risk strategies were named as diversification, precautionary savings and social networks. Results provide practical insights for policy changes relevant in motivating the adoption of organic practices, increasing smallholder farmers' capacity to manage risk and driving growth in the organic food market.展开更多

The study shows that the risk preference of an agent directly correlates with the incentive compensation coefficient of principal, order quantity of principal and production capability level of the agent. The principal should offer an appropriate incentive contract according to the risk preference of the agent, or choose an agent holding a different risk preference to establish the supply chain.展开更多

This paper aims to provide a group decision making method where DMs use the IFPRs to indicate their preferences with uncertain weights. To begin with, a model to derive weight vectors of alternatives from IFPRs based on multiplicative consistency is presented. Specifically, for any IFPR,by minimizing its absolute deviation from the corresponding consistent IFPR, the weight vectors are generated. Secondly,a method to determine relative weights of DMs depending on preference information is developed. After that we prioritize alternatives based on the obtained weights considering the risk preference of DMs. Finally, this approach is applied to the problem of technical risks assessment of armored equipment to illustrate the applicability and superiority of the proposed method.展开更多

Thus, to provide subsidies to forest farmers is an important means to encourage the farmers' enthusiasm to manage the forest and promote the healthy and sustainable development of private forest. In order to reduce the supply-demand contradictions and improve the implementation effects of the subsidies system, the design of the system should be based on the real needs of forest farmers. On this basis, a questionnaire survey was designed in this paper to study the preferences of forest farmers to different types of subsidies in the southern collectively owned forest and the influencing factors were analysed by the Logistic Model to search for the reasonable design of the system. It was concluded that the forest farmers with different backgrounds show different preference to the subsidies, which, to a certain extent, reflects the development bottlenecks of forestry, and lays a foundation for the design of subsidies system.展开更多

The varieties tested only on station evaluation trials without taking the data from the farmers' fields by not including farmers as partners for variety evaluation are the reasons of low adoption of varieties. In this regard, a participatory methodology was followed by conducting a number of participatory trials in the farmers' fields during 2012-2014 in six districts of Kashmir Valley, India. The mother trials in the farmers' fields showed that the test variety SKUA-408 consistently and significantly out yielded Jhelum and farmers' variety followed by Shalimar rice 3 (SR3). The other released varieties like SR1 and SR2 could not perform nicely in the farmers' fields because of late maturity. After making the t-test comparison of baby trials (paired plots), the mean yield superiority of test varieties SKUA-408, SR3, and SKUA-403 over farmers' variety during 2013 was around 23, 25, and 22%, respectively, whereas in 2014 the respective yield advantage was recorded as 16.3, 17.7, and 16.2%. In all districts, SKUA-408 and SR3 were significantly preferred by farmers (P〈0.05 or 0.01) in terms of pre-harvest traits namely, tillering ability and general phenotypic acceptability, early maturity and biomass and for post-harvest traits such as general cooking quality besides, the intention to grow the variety for next year. Adoption and dissemination of SKUA-408 began in 2014 from the farm-saved seed in the form of farmer to farmer seed exchange. Farmers are the end users of a variety so the decision by the farmers while judging the variety should be taken into consideration to make the varietal choice more effective for its widespread adoption.展开更多

A participatory rural appraisal was conducted in two main rice cultivation areas in Burkina Faso to assess farmers’ awareness of rice production constraints with emphasis on rice yellow mottle disease (RYMD) and its management. Farmers’ preference for rice varieties to be used in the breeding program was also assessed. Major concerns for rice cultivation as perceived by farmers were water shortage and RYMD. However, relative importance of each constraint depended on the survey areas, RYMD being prominent at Banzon while water shortage predominated at Mogtedo. Mogtedo farmers preferred rice variety FKR19 because of its tolerance to drought. At Banzon, farmers’ first criterion was taste which was reflected in the choice of variety FKR18. Yield was also a major criterion in both areas, positioning NERICA varieties FKR56N, FKR62N, and FKR60N among the top preferred varieties. Farmers mentioned RYMD as the most important rice disease. Most farmers used varietal shifts or pesticide treatments for RYMD management. RYMD incidence reached 28% in average at Banzon over the 2012-2013 main growing seasons. In rice varieties FKR56N, FKR62N and TS2, diseased plants yielded 79.3% less than the healthy ones. Accordingly, based on disease incidence, overall yield loss in the study area was estimated at 22.3%. Altogether, rice production can be significantly increased by taking RYMD into account in a participatory rice breeding strategy.展开更多

Efficient use of inputs has been one of the key objectives of agricultural policies in all over the world. Therefore, studies continue about production of new seeds with high yield and resist to diseases. The 66.7% of the total seed production in Turkey are met by the private sector (hybrid sunflower, corn, potato, soybean, cotton and vegetable seed). And 53.4% of the total sunflowers in Turkey are grown in Thrace region. It is therefore appropriate to be selected as the research area. In this regard, the aim of this study was to examine the dynamics in seed sector and particularly investigate the sunflower seed purchasing behavior of farmers with special attention to Thrace region. As a methodology, 198 questionnaires which pursued sunflower farm activities in the region were utilized. As a result of the descriptive statistics, it could be concluded that almost 20% of seed supply in Turkey is imported and that 70%-80% of it is directly used as an “input” for growing vegetative products and the remaining is used as “intermediate goods” for growing “certified seeds” for domestic or international markets.展开更多

文摘The paper combs the problems about living difficulties of farmers and marketing economy in the risk society and puts forward another point of view that with the theory of risk society,reconsider the dilemma of living choices of farmers under the background of marketing economy.On the basis of the statistics,the paper discloses the trend of larger and larger disparities of incomes between urban and rural areas;the paper explains the risks and uncertainties of life choices with the background of deepening marketing economy.In order to understand the life dilemma of farmers and marketing economy in the risk society,the paper makes an analysis from perspectives of the relationships between risk society and markets,the risks of farmers' living choices.The results show that in the risk society,because of the division space from time,the personal farmers are devoid of the safe environment.Then the situation deepens to worse.In addition to the organization which is not in charge results in a situation that the personal farmers would take all risks by themselves.
文摘This study analyzed the determinants of climate change risk perception among cassava farmers in Anambra state, Nigeria. The specific objectives were to describe the socio-economic characteristics of cassava farmers in the area and to examine the farmers’ climate change risk perception through examining their perception of the various sources of climate change risk. Multi-stage sampling technique was used to select one hundred and sixty (160) respondents who were selected from 40 communities and 8 Local Government Areas from across the four Agricultural Zones of the state. Data were obtained through the administration of structured questionnaire to the respondents. Data collected were analyzed using descriptive statistics, weighted mean obtained from Likert scale, and Tobit regression model. The results of the socioeconomic characteristics of farmers showed that majority of the farmers had formal education and only 15.19% had no formal education, 56.74% of the farmers had 11 years of farming experience. The farmers’ risk perception showed that the most important risk factors perceived by cassava farmers in their farm were flooding/erosion, increased frequency and intensity of rainfall and incidence of pest and diseases. The factors that influenced the farmers’ level of risk perception included age, level of education, access to extension agents and access to climate change information. Based on the findings of cassava farmers’ level of risk perception, it was inferred that the farmers have reasonable perception of climate change risk. It was therefore recommended from the findings of this research that there is need for effective and functional extension services and provision of enabling environment and policies that will help boost the socio-economic welfare of farmers as this will significantly help in the management of climate change risk in the study area.
文摘To overcome the subjectivity of experts in the process of risk response scheme selection, according to the theory of group decision making, a selection method and flow of the risk response schemes for a mining project was proposed based on fuzzy preference relation and consistency induced ordered weighted averaging (C-IOWA) operator,which can overcome the loss of information in the process of group decision making to a great degree, and improve its efficiency and quality.A numeric example was introduced to illustrate the application of the method, also validating the method as scientific and practicable.
文摘The article assesses the determinants of farmers' decisions to participate in organic farming, eliciting farmers risk preferences and empirically analysing farmer's sources of risk and risk management strategies. The ordered probit results indicate that older farmers, who are less risk averse and reside in the sub-ward Ogagwini, Ezigani and Hwayi were more likely to be certified organic. Similarly, the propensity to adopt organic farming is positively correlated to household size, livestock ownership, asset base and tenure security. At higher pay-offs, farmers were intermediate to moderately risk-averse, with little variation according to personal characteristics. In general, price, production and financial risks were perceived as important sources of risk. Seven principal components, explaining 66.13% of the variation were extracted. Socio-economic factors having a significant effect on the various sources of risk were age, gender, education, location, information access and risk taking ability. The dimensions of risk strategies were named as diversification, precautionary savings and social networks. Results provide practical insights for policy changes relevant in motivating the adoption of organic practices, increasing smallholder farmers' capacity to manage risk and driving growth in the organic food market.

文摘With respect to different risk preference of an agent in a supply chain, linear-contract models are designed according to the principal-agent theory. The study shows that the risk preference of an agent directly correlates with the incentive compensation coefficient of principal, order quantity of principal and production capability level of the agent. The principal should offer an appropriate incentive contract according to the risk preference of the agent, or choose an agent holding a different risk preference to establish the supply chain.

文摘Intuitionistic fuzzy preference relation(IFPR) is a suitable technique to express fuzzy preference information by decision makers(DMs). This paper aims to provide a group decision making method where DMs use the IFPRs to indicate their preferences with uncertain weights. To begin with, a model to derive weight vectors of alternatives from IFPRs based on multiplicative consistency is presented. Specifically, for any IFPR,by minimizing its absolute deviation from the corresponding consistent IFPR, the weight vectors are generated. Secondly,a method to determine relative weights of DMs depending on preference information is developed. After that we prioritize alternatives based on the obtained weights considering the risk preference of DMs. Finally, this approach is applied to the problem of technical risks assessment of armored equipment to illustrate the applicability and superiority of the proposed method.

文摘Forest farmers are the basic micro-subjects in southern collectively owned forest, and their willingness towards forest management directly influences forestry development. Thus, to provide subsidies to forest farmers is an important means to encourage the farmers' enthusiasm to manage the forest and promote the healthy and sustainable development of private forest. In order to reduce the supply-demand contradictions and improve the implementation effects of the subsidies system, the design of the system should be based on the real needs of forest farmers. On this basis, a questionnaire survey was designed in this paper to study the preferences of forest farmers to different types of subsidies in the southern collectively owned forest and the influencing factors were analysed by the Logistic Model to search for the reasonable design of the system. It was concluded that the forest farmers with different backgrounds show different preference to the subsidies, which, to a certain extent, reflects the development bottlenecks of forestry, and lays a foundation for the design of subsidies system.

文摘In mountain agriculture, early maturity, high grain yield and high biomass are generally considered as farmer preferred traits in rice crop in addition to a multiple set of traits collectively responsible for variety adoption or rejection. The varieties tested only on station evaluation trials without taking the data from the farmers' fields by not including farmers as partners for variety evaluation are the reasons of low adoption of varieties. In this regard, a participatory methodology was followed by conducting a number of participatory trials in the farmers' fields during 2012-2014 in six districts of Kashmir Valley, India. The mother trials in the farmers' fields showed that the test variety SKUA-408 consistently and significantly out yielded Jhelum and farmers' variety followed by Shalimar rice 3 (SR3). The other released varieties like SR1 and SR2 could not perform nicely in the farmers' fields because of late maturity. After making the t-test comparison of baby trials (paired plots), the mean yield superiority of test varieties SKUA-408, SR3, and SKUA-403 over farmers' variety during 2013 was around 23, 25, and 22%, respectively, whereas in 2014 the respective yield advantage was recorded as 16.3, 17.7, and 16.2%. In all districts, SKUA-408 and SR3 were significantly preferred by farmers (P〈0.05 or 0.01) in terms of pre-harvest traits namely, tillering ability and general phenotypic acceptability, early maturity and biomass and for post-harvest traits such as general cooking quality besides, the intention to grow the variety for next year. Adoption and dissemination of SKUA-408 began in 2014 from the farm-saved seed in the form of farmer to farmer seed exchange. Farmers are the end users of a variety so the decision by the farmers while judging the variety should be taken into consideration to make the varietal choice more effective for its widespread adoption.
文摘There are problems of inadequate natural endowment and weak stamina in the development of micro-credit loans to farmers in China. Specifically,existing problems include narrow profit space,serious non-agricultural trend of funds,high dependence on government support,short life cycle,and constantly increasing operating risks. These problems are related to endogenous drawback in design,defect in operating procedure,lagging in relevant policies and measures,and vacancy in risk compensation mechanism.
文摘Rice improvement for disease resistance has scarcely involved farmers’ knowledge in Sub-Saharan Africa. A participatory rural appraisal was conducted in two main rice cultivation areas in Burkina Faso to assess farmers’ awareness of rice production constraints with emphasis on rice yellow mottle disease (RYMD) and its management. Farmers’ preference for rice varieties to be used in the breeding program was also assessed. Major concerns for rice cultivation as perceived by farmers were water shortage and RYMD. However, relative importance of each constraint depended on the survey areas, RYMD being prominent at Banzon while water shortage predominated at Mogtedo. Mogtedo farmers preferred rice variety FKR19 because of its tolerance to drought. At Banzon, farmers’ first criterion was taste which was reflected in the choice of variety FKR18. Yield was also a major criterion in both areas, positioning NERICA varieties FKR56N, FKR62N, and FKR60N among the top preferred varieties. Farmers mentioned RYMD as the most important rice disease. Most farmers used varietal shifts or pesticide treatments for RYMD management. RYMD incidence reached 28% in average at Banzon over the 2012-2013 main growing seasons. In rice varieties FKR56N, FKR62N and TS2, diseased plants yielded 79.3% less than the healthy ones. Accordingly, based on disease incidence, overall yield loss in the study area was estimated at 22.3%. Altogether, rice production can be significantly increased by taking RYMD into account in a participatory rice breeding strategy.
文摘Selection of suitable seed in agriculture has great importance in terms of scarce resources and efficient use of facilities. Efficient use of inputs has been one of the key objectives of agricultural policies in all over the world. Therefore, studies continue about production of new seeds with high yield and resist to diseases. The 66.7% of the total seed production in Turkey are met by the private sector (hybrid sunflower, corn, potato, soybean, cotton and vegetable seed). And 53.4% of the total sunflowers in Turkey are grown in Thrace region. It is therefore appropriate to be selected as the research area. In this regard, the aim of this study was to examine the dynamics in seed sector and particularly investigate the sunflower seed purchasing behavior of farmers with special attention to Thrace region. As a methodology, 198 questionnaires which pursued sunflower farm activities in the region were utilized. As a result of the descriptive statistics, it could be concluded that almost 20% of seed supply in Turkey is imported and that 70%-80% of it is directly used as an “input” for growing vegetative products and the remaining is used as “intermediate goods” for growing “certified seeds” for domestic or international markets.
