Examining cover crop agri-environmental program participation: Evidence from a western US farmer survey

Agri-environmental programs (AEPs), which pay farmers to adopt conservation practices, are increasingly important environmental and agricultural policy tools used in both the US and the EU. Despite large budgetary shares allocated in a 20-year application window, several studies identify lower-than-expected environmental outcomes. In the US, reasons for low environmental outcomes include low participation rates, lack of program awareness, and poor targeting levels. Research has identified low levels of awareness and variation in participation across the US in the Environmental Quality Incentives Program (EQIP), the largest working lands program in the US. Using a survey of Western US farmers, this paper provides an analysis of awareness and participation levels in cover crop AEPs in the Western US. Second, this paper analyzes motivations and barriers to participation in cover crop AEPs through the Environmental Quality Incentives Program (EQIP) and the Conservation Stewardship Program (CSP). Third, the paper uses a survey experiment to examine different types of incentives. The results highlight that participation is low due to lack of awareness and policy barriers. Using a logistic regression, predictors of AEP participation include frequent contact with NRCS, having a succession plan, and a positive attitude toward governments’ role in conservation programs. The survey experiment found that non-financial factors, such as more information on cover crops, is an effective policy incentive.

Population, distribution, biomass, and economic value of Equids in Ethiopia.

Equids play a crucial role in the Ethiopian economy, transporting agricultural inputs and outputs in the dominant subsistence agricultural systems and the critical link for value chains throughout the country. However, these species are often neglected in policies and interventions, which reflects the data and information gaps, particularly the contribution of working equids to Ethiopia. To assess population dynamics, distribution, biomass, and economic value of equids in Ethiopia. Equine population data were obtained from the Ethiopian Central Statistics Agency (CSA) annual national agriculture surveys published yearbooks from 2004 to 2020. Parameters such as the number of effective service days and daily rental value were obtained from interviews and literature to estimate the stock monetary and service value of equids. Descriptive statistics were used to assess population dynamics and the geographical distribution was mapped. The estimated total Ethiopian equid population increased by more than doubled (by 131%) between 2004 and 2020 from 5.7 (4.9-6.6) million to 13.3 (11.6-15) million with 2.1 million horses, 10.7 million donkeys, and 380 thousand mules. Similarly, the number of households owning a working equid has increased. Equine populations are unevenly distributed across Ethiopia, although data were lacking in some districts of the country. The per human-capita equine population ranged from 0-0.52, 0-0.13, and 0-0.02 for donkeys, horses, and mules, respectively. The equid biomass was 7.4 (6.3-8.4) million Tropical livestock unit (TLU) (250 kg liveweight), 10% of total livestock biomass of the country. The stock monetary value of equids was USD 1,229 (651-1,908) million, accounting for 3.1% of total livestock monetary value and the services value of equids was USD 1,198 (825-1,516) million, which is 1.2% of Ethiopian 2021 expected GDP. The Ethiopian equine population has grown steadily over the last two decades. Equids play a central role in transportation and subsistence agriculture in Ethiopia and contribute significantly to the national economy. This pivotal role is insufficiently recognized in national livestock investments.

Environmental Impacts of Rice Intensification Using High-Yielding Varieties: Evidence from Mazandaran, Iran

This article aims to show the potential contribution of high-yielding rice varieties to achieve sustainable intensification in paddy farming, by focusing on a developing country. A comparative life cycle assessment of traditional vs. high-yielding varieties is carried out by comparing the area-based and yield-based results. Primary data are collected through a farm survey (49 farms in the Mazandaran province, Iran; spring 2018). The results highlight that high-yielding varieties can reduce the yield-scaled impacts. However, area-scaled impacts are subject to increase for most impact categories. Statistically significant trade-offs involve global warming potential (+13% per ha and −28% per t in high-yielding varieties) and fossil resource depletion (+15% per ha and −26% per t in high-yielding varieties). Pesticide management is the most alarming practice. High-yielding varieties increase pesticide consumption and related toxicity impacts both per t and per ha. This study is a new contribution to the literature by improving and broadening the mainstream productivity perspective of current life cycle assessment research about crop varieties. The lessons learnt from this study suggest that the trade-offs between yield-scaled and area-scaled impacts should be carefully considered by decision-makers and policymakers, especially in developing countries that, like Iran, are affected by the overexploitation of natural resources. Targeted policy and the development of farmer education and advisory services are needed to create the enabling conditions for farm management changes, including conscious use of production inputs while avoiding heuristics.

Can crop insurance help optimize farmers’ decisions on pesticides use? Evidence from family farms in East China

Pesticides are important agricultural inputs, which can effectively reduce crop growth risk, but irrational use of pesticides also brings major challenges to the green development of agriculture. This paper constructs a theoretical framework of the effect of crop insurance on pesticides usage. Then using family farm survey data in East China, we measure the marginal value cost ratio (MVCR) of pesticides use through the improved damage abatement production function (DAPF), and empirically analyze the impact of crop insurance on MVCR of pesticides use by employing the endogenous treatment effect model (ETEM). The results show that 42.6% of family farms in the sample area purchased crop insurance, and almost all family farms overused pesticides, but the degree was relatively lower among the family farms with crop insurance. Crop insurance has a significantly positive effect on the MVCR of pesticides use, which indicates that it can optimize farmers’ pesticides use behavior. This conclusion is also confirmed by several robustness checks. Thus, the promotion of agricultural insurance can play the role of promoting the green development of agriculture to a certain extent.

Heterogeneity in farmers’ stage of behavioural change in intercropping adoption: an application of the Transtheoretical Model

Despite its potential economic and environmental benefits, intercropping adoption remains limited in Europe. Drawing upon the Transtheoretical Model, this paper views adoption decision as stages of behavioural change. The paper aims to investigate socioeconomic, behavioural, and policy factors associated with stage of change in intercropping adoption in Sweden. Exploratory factor analysis and generalized ordered logit regression were performed on data from a nation-wide farmer survey conducted in 2021 with 388 usable replies. Results show that farmers with better knowledge of intercropping, a higher evaluation of financial benefits and ease of intercropping, and ley growers were more likely to progress to higher stages of the adoption process. Farmers who have higher perceived seed separation costs, a lower education level, and are older tend to remain at lower stages. Perceived environmental benefits of intercropping, household income, and instrumental values of farming could turn non-adopters into either potential adopters or actual adopters. We found no significant association between policy support and stage of change in intercropping adoption. Policy implications aimed at fostering intercropping adoption were discussed.

The effects of agricultural machinery services and land fragmentation on farmers' straw returning behavior

AbstractStraw returning is important for rural ecological management and sustainable agricultural development. Using farm survey data for Anhui Province, China, in 2020, we applied the double‐hurdle model to investigate the impact of agricultural machinery services and land fragmentation on farmers' straw‐returning behavior, and to explore the relationship between agricultural machinery self‐service and outsourced service. Self‐service had a significant positive effect on farmers' straw‐returning behavior, while outsourced service had a significant positive effect only on degree of adoption. Land fragmentation had a significant negative effect on farmers' straw‐returning behavior, and significantly inhibited the effect of self‐service on adoption decision. Complementarity existed between self‐service and outsourced service in farmers' straw‐returning adoption decision, and the effect was more pronounced among smaller‐scale farmers. There was significant substitutability between self‐service and outsourced service in degree of adoption among larger‐scale farmers. Transfer and integration of rural land, increasing agricultural machinery purchase subsidy, upgrading farmers' self‐service capability, and promoting development of socialized agricultural machinery services should be implemented to promote crop straw returning.

Using microbial biocontrol for disease control in French vegetable production: An analysis of the perspectives of farmers and farm advisors

Microbial biocontrol products are increasingly available as alternative solutions to chemical control for the management of vegetable diseases. However, their use is still limited. A study was carried out to analyse this situation and identify the needs and limits encountered by users of biocontrol agents, with the goal of suggesting potential ways of improvement. A survey of French vegetable farmers and farm advisors was therefore conducted. First, online questionnaires were disseminated to more than 500 professionals, with queries on their use of biocontrol products, targeted diseases, and perceived efficacy. In a second step, face-to-face interviews were performed with 42 of the 217 respondents, to obtain in-depth technical information about successes and difficulties encountered by users in the implementation of biocontrol. The answers to the online questionnaires highlighted that only few biocontrol products were known and used, and their efficacy was perceived as low by users. This diagnosis was confirmed by the face-to-face interviews. While users showed awareness of the benefits of applying biocontrol products to manage plant diseases, they also reported that unstable efficacy, together with difficulties in using biocontrol along with other cultural practices, resulted in questionable interest. More than 85 % of the users expressed the need for additional technical benchmarks on the efficacy of marketed biocontrol products and for practical guidelines helping to choose the most adequate products for specific situations and to obtain information about the most efficient way to use biocontrol solution. Propositions are made to address the needs of users and to foster a wider use of microbial biocontrol agents in vegetable crops.

Analysis of Management Practices and Breeders' Perceptions of Climate Change's Impact to Enhance the Resilience of Sheep Production Systems: A Case Study in the Tunisian Semi-Arid Zone.

Global climate change inflicts unambiguous risks on agricultural systems and food security. Small ruminants are known for their ability to adapt to changing environmental conditions. This paper aims to characterize sheep production systems in a vulnerable agricultural zone and the breeders' perceptions of climate change to apprehend challenges that they are confronting, and formulate resilience actions. The data analysis is based on 94 semi-structured surveys of sheep farmers carried out in the Tunisian semi-arid region. The PCA analysis results revealed three main sheep production systems. The agro-pastoral rain-fed system (AGPRF) is dominant (55%), with large farms and common pastures integrating cereals and fodder. The agro-pastoral irrigated system (AGPI: 20%) is characterized by small-area and forage irrigation (1.8 ha) and a smaller number of ewes but a greater use of animal feed supplementation. The agro-sylvo-pastoral system (AGSP: 25%) is a system where grazing is based on common lands and using tree sub-products, while the agricultural area is exclusively used to cultivate cereal crops. Sheep breeders' climate perceptions are summarized as unpredictable climate events, a decrease in precipitation, and an increase in temperature. Resilience actions principally consist of reducing flocks' numbers, using alternative local feed, fodder, and water resources, and building more shelters and planting more trees in the grazing areas. Nevertheless, cost-effectiveness should be considered in such vulnerable zones to insure the sheep production systems' sustainability.

Farmers’ futures: an application of the Delphi method in the context of Finnish agriculture

In Finland, agriculture is practiced in variable growing conditions that are further challenged by climate change and under external pressure caused by international competition, changing consumer preferences and demands, and the renewal of the European Union Common Agriculture Policy and Paris Agreement climate targets. Futures studies in agriculture have focused on scenario building with expert panels, though usually without farmers’ involvement. This study focuses on farmers’ views of shaping the future of Finnish agriculture. It builds on the disaggregative Delphi method and combines interviews and a representative survey of Finnish farmers. The study is based on a bottom-up process in which a farmer panel of 20 farms defined their views of the future in a semi-structured thematic interview. The views were turned into statements in a structured survey sent to the second panel, which comprised all Finnish farmers who had received agricultural subsidies in 2016, with 4401 respondents. The results were analyzed using quantitative factor analysis, which produced five future images for Finnish agriculture. The images were shown to the original farmer panel for reflection. They considered the probability of each future image and their own role in it. Technology solves as a future image was most favored by farmers, followed by Ecological and specializing small-scale production image. Business-as-usual was the least likely future images according to the interviewed farmers. This paper describes the process and discusses both methodological benefits and pitfalls, as well as farmers’ future views of the forthcoming decades.

COVID-19 induced shocks and its implications for human capital development

BackgroundCOVID-19 has delivered an enormous shock to the global economy, triggering the deepest recession in eight decades, almost three times as deep as the 2009 global recession. Of all the nations in Africa, Nigeria remains one of the nations with a huge and significant impact on the human capital.MethodsHence, here we employed the recent nationally representative data from Nigeria - the COVID-19 National Longitudinal Phone Survey 2020-World Bank Living Standards Measurement Study Integrated Agriculture Survey (LSMS-ISA), a harmonized dataset to explore how the COVID-19 induced shocks affected households’ human capital development (using health and education outcomes).ResultsThe results indicate that the COVID-19 induced shocks impact on both health and education in Nigeria. Interestingly, access to social safety nets had a positive association with the health and education outcomes. The study concludes that households’ access to social safety nets, particularly during the COVID-19 pandemic aids in the development of the nation’s human capital. Therefore, effectively enhancing household’s resilience and strengthening human capital development require positive and considerable innovation, maybe over a period of years. Hence, just an access to the national social safety nets programs or social programs may not be as effective as expected. Therefore, it may not be as successful as intended to just have access to national social safety net programs or social programs that contribute or transfer negligible amounts to the vulnerable recipients over short time frames.

Understanding specific gender dynamics in the cowpea value chain for key traits to inform cowpea breeding programs in Malawi, Mozambique and Tanzania.

Cowpea is an important food and nutrition security crop in Malawi, Mozambique and Tanzania and it is mainly produced by women farmers mainly on a subsistence scale. The majority of these farmers use local varieties despite the availability of improved varieties in the region. Low acceptability and adoption of improved varieties have also hampered cowpea breeding efforts. The low adoption, especially among women farmers, has been attributed to the failure by breeding programs to involve farmers in the process of designing and developing improved varieties with a view to meeting their priorities and preferences. Despite women constituting the majority of cowpea farmers in these countries, no comprehensive gender analysis on cowpea value chain had been instituted to understand the traits that are gender and youth responsive and how to incorporate them in the product profiling so that the developed varieties benefit men, women and youth. The main objective of the gender study was, therefore, to identify preferred traits by different gender groups within the whole cowpea value chain to inform cowpea breeding programs in the three countries. The study employed quantitative and qualitative methods to elucidate preferences, including value chain mapping, a quantitative survey of farmers, focus group discussions and key informant interviews targeting farmers/consumers, traders, policymakers and processors. Results showed that the top-ranking traits in order of importance across the countries and gender were; (1) high grain yield, (2) good grain taste, (3) early maturity time, (4) large grain size, (5) good leaf taste and (6) short cooking time. It was further noted that different gender groups preferred almost similar traits though minor variations were noted in terms of prioritization of these traits. These results have had two major influences on our cowpea breeding program: firstly, the breeding program changed the way it prioritizes traits to include ones that reflect the needs of men, women and the youth in the cowpea value chain. Secondly, our breeding objectives are closely aligned to gender differences in the target population of farmers and other users, by incorporating key priority traits that address the needs of both men and women, including the youth. That is to say, product targets and specific product profiles are more gender sensitive. Since the breeding work is ongoing, the expectation is that the development of improved varieties resulting from this gender sensitive process will translate into higher adoption levels of these varieties (compared with previous releases), which might have ripple effects on food, nutrition and income security in the region.

The Ageing Crisis Threatening Farming in Ethiopia: An Analysis of Youth Involvement in Agriculture

This study examined youth labor force participation in agriculture and factors impeding effective participation in Ethiopia using the 2011-2018 data from the Living Standards Measurement Survey-Integrated Survey of Agriculture (LSMS-ISA). The analytical tools included both descriptive statistics and econometric analysis. Summary statistics show that the average age of the respondents was 47 years, thus they are not at an economically active age. This is an upward trend of 52 years in 2018 compared to 44 years in 2011. The ordinary least square (OLS) regression result indicated that for every 1 unit increase in the independent variable (time), there will be a 1.01 increase in the dependent variable (farm age). The result showed that the increase in time affected age of the farming positively and significantly. The evidence suggested farming population in Ethiopia is growing older and reduced involvement of youth (14.4%). The results also revealed low participation of youth in agriculture activities which increases youth unemployment. In turn, the total dependency ratio in the population equals 102.7. This high dependency ratio means that the ‘dependents’ in society are more reliant on a smaller number of working-aged people, which suggests that for every 1027 dependents, there are roughly 1000 working-age people providing them food through farming. The review result showed youth participation in Ethiopian agriculture is influenced by limited access to land, low attitude on agriculture (attitudinal problems), inadequate access to financial services, problems of rural life, and backwardness of agricultural tools. The study suggests that efforts to shape future work in Ethiopian agriculture should include among other things, access to land and provision of credit facilities. The study pointed out that the efforts to shape the future of agricultural work in Ethiopia should ensure the availability of land and credit.

Adoption of irrigation scheduling in the South African sugarcane industry: the use of a demonstration trial to bring about change

In the South African sugarcane industry, as in many countries, poor adoption of irrigation scheduling is common, leading to ineffective use of irrigation water and loss in yield and income. The reasons for the lack of adoption include economic constraints, difficulty with implementation and human perceptions. To demonstrate the benefits of effective irrigation scheduling under local conditions, a demonstration trial was conducted over 5 years at Pongola, South Africa. Here, a fixed irrigation schedule (control) was compared with three scheduling treatments: (1) the MyCanesim® computer model with data from an automatic weather station; (2) soil-water data from a capacitance probe; and (3) a combination treatment, where MyCanesim® was integrated with a capacitance probe. The number of stress days from either under- or over-irrigation, along with the RV (recoverable value) yield, irrigation applied, irrigation water productivity (IWP) and financial benefits was used to assess each treatment. The adoption of irrigation scheduling was also evaluated through farmer surveys before and after the trial. When compared to the fixed-cycle control, the use of irrigation-scheduling techniques resulted in an increase of up to 13% in RV yield, a reduction of up to 58% in irrigation water applied, improved IWP of up to 23.9 t cane/100 mm of irrigation and financial benefits of up to ZAR10,487/(ha · a) (USD698/(ha · a)). The combination treatment incurred the least water-stress days, 79% lower than the control. Farmer surveys showed an increase of 45% in the adoption of irrigation scheduling, from 11% (n = 111) in 2014 to 56% (n = 100) in 2020. Although site-specific, the trial results show substantial benefits that can be realised by scheduling irrigation. The trial results compare well to other similar studies, showing that the results can be used in other areas to promote the adoption of irrigation scheduling.

Unlocking Sows’ Welfare: The Farm-Level Economic Impact of Phasing out Farrowing Crates for Sows in the European Union’s Pig Breeding Industry

The main purpose of this study is to assess the farm-level economic consequences of the planned introduction of a ban on farrowing crates for sows in the EU pig sector, being a response by the European Commission to the ‘End the Cage Age’ Initiative. The impact assessment was carried out in three stages: farm-level analyses based on 225 farm surveys carried out in EU member states and expert consultations, assessments for five alternative scenarios, and the aggregation (scaling-up) of the scenario analysis to the EU-27 sectoral impact. Our findings indicate that the ban on farrowing crates is expected to cause a decrease in the sow population by 21–23%, depending on the scenario, and piglet output in the EU owing to increased sow space requirements, a reduction in production efficiency, and a significant demand for investments. The transition to alternative farrowing systems will lead to increased variable costs related to the farrowing period, namely, veterinary expenses, labour costs, and sow feed costs, as well as expenses associated with higher piglet mortality and increased sow replacement rates. The lower density, resulting from the larger space allowance per sow in free-farrowing systems (approximately 5.5 m2 in free farrowing with temporary confinement and 7 m2 in systems without confinement) will also cause fixed costs per unit (per sow or piglet) to rise in proportion to the decline in the sow herd. Expressed as a percentage of the total production costs per piglet, we can expect a 6–10% increase in the total production costs. The implementation of free-farrowing systems on pig farms will necessitate investments in the modernisation of the existing buildings and new pens for sows. Depending on the scenario, the value of investments ranged from 3.8 to 6.7 billion EUR, at 2021 prices. It should be recognised that beyond the actual improvement in the welfare of sows, there are lingering concerns, including increased production costs, higher piglet mortality rates, and heightened risks to employees. It is essential to consider providing financial assistance to support farms in making a smooth transition to the new systems, as well as an extended transition period to ensure a painless shift.

Dietary exposure levels to polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and non-ortho-polychlorinated biphenyls in US meat, poultry and siluriform fish from 2018 to 2019

Daily dietary exposure estimates from beef, pork, chicken, turkey and siluriform fish were calculated using toxic equivalency (TEQ) data from the U.S. Department of Agriculture’s survey of dioxins and dioxin-like compounds (DLCs) in the domestic meat supply and consumption data. Exposure estimates for the whole population and age groups were based on mean consumption of a commodity and mean or 90th percentile TEQ dioxin levels from the survey. Ratios of the exposure estimates to the U.S. EPA oral reference dose (RfD) of 0.7 pg TEQ/kg bw/day were calculated to determine if domestic meat might contribute materially to consumer exposure. In general, normal consumption of lean beef, pork, chicken and turkey will not cause exposures exceeding the RfD. Non-lean meats will have higher dioxin levels as dioxins accumulate in fat, therefore consumption of non-lean meat might cause higher exposure than compared to lean meat. However, on a mean basis, none of the exposure estimates for non-lean beef, pork, chicken or turkey exceeded the RfD for any of the age groups. For some age groups, especially toddlers, there are commodities such as non-lean beef in the 90th percentile of dioxin TEQs and siluriform fish that might exceed the RfD on occasion.

Factors Affecting the Rice Yield During the Rainy Season Among Farmers in Southeastern Cambodia

A research study utilized the Cobb-Douglas production function to examine the elements influencing paddy production during the wet season in three rural provinces of Cambodia. This analysis was based on data gathered from a survey of farmers’ households conducted in 2022. The study discovered that the use of fertilizers and herbicides, the size of the family, and income from off-farm sources significantly impacted the output of wet-season paddy. A one percent increase in the use of fertilizer, herbicide, and family size resulted in an increase in rice output by 0.06 percent, 0.04 percent, and 0.05 percent respectively. Furthermore, a one percent increase in the age of the household head, hired labor, and off-farm income led to an increase in rice yield by 0.08 percent, 0.11 percent, and 0.05 percent respectively. The use of seeds, pesticides, household labor, and the education level of the household heads were found to enhance rice yields in southeastern Cambodia. However, these production relationships varied significantly across different regions. The study concluded that higher yields during the rainy season improved the effectiveness of paddy production, primarily due to the increased responsiveness to fertilizer application.

End of the Cage Age? A Study on the Impacts of the Transition from Cages on the EU Laying Hen Sector

This paper’s main objective is to assess the impacts of the ban on cages for housing laying hens, planned by the European Commission to raise animal welfare standards beyond the level set in the current legislation. The farm-level economic assessments of the ban were carried out in three stages: farm surveys and expert consultations, farm-level analyses, and aggregation to the EU-27 egg production sector. Four scenarios were constructed. All financial estimates were conducted with fixed prices from the year 2021 for which the reference scenario was built. Alternative hen-housing systems were barn (Voliera), free range, and organic. Until now, more than 50% of laying hens in the EU have already been transferred to alternative systems. The remaining part is subject to the transition. The basic assumptions included a reduction in yields due to the required lower densities and specifics of the production systems. A factor strongly differentiating the scenarios is likelihood of exists form the sector, as declared in the survey by many farmers, mainly those reaching retirement age without successors and keeping relatively small flocks of hens. The introduction of the ban will cause a decrease in egg production, varying between the scenarios. Substantial investments will be required within the range of 2–3.2 billion EUR, depending on the scenario.

Data Driven Identification of Injury Risk Factors During Expansion on Irish Dairy Farms

ABSTRACT Objectives This paper sought to determine risk factors of occupational injury in the Irish dairy farming sector and to estimate the roles of both dairying expansion and the discipline of agricultural extension in influencing reducing injury occurrence. Methods Data for this study was obtained via the Irish National Farm Survey (NFS). In total, 260 farm (83.6% of NFS dairy farm sample) workplace injury survey questionnaires were completed by NFS recorders by interviewing principal farm operators for year 2017. Injury survey data was analysed for 48 variables in conjunction with NFS core farm socio-economic, physical and financial data. Additionally, core data from 2010 for 78.5% of farms surveyed in 2017 was included in the study. Data were analysed using a three-step statistical testing process which met all Binary Logistic Regression assumptions. Results The study found that dairy farms had a higher farm workplace occupational injury level compared to a previous study. The study data indicates occurrence of elevated injury levels on farms which expanded and which were intensively managed from a milk production perspective. Farm expansion was associated with increased labor units used and increased investment per hectare. The study also found that use of extension services and farm discussion group participation were not associated with injury occurrence. Conclusions This study demonstrates how a retrospective farm workplace occupational injury survey of Irish dairy farms, analysed in combination with farm business data can be used to identify injury risk factors, including those associated with production expansion. Irish dairy farms have a heightened farm workplace occupation injury level while dairy production expansion increased injury levels. Extension engagement did not influence on injury levels. Approaches to improve farm safety on dairy farms are outlined.

Analysis on Driving Factors, Reduction Potential, and Environmental Effect of Inorganic Fertilizer Input in Chongqing

In this study, we sought to quantify the effect of planting structure change on fertilizer input and environmental cost in Chongqing and develop scientific and rational strategies for chemical fertilizer reduction. Based on the crop fertilizer quota standard and large sample farmer survey data under the medium productivity level in Chongqing, we evaluated and analyzed the application reduction potential and environmental benefits of fertilizer with the difference method and life cycle assessment. The results showed that:① since Chongqing became a municipality directly under the central government (1997), Chongqing crop planting structure had greatly changed, and the proportion of food crop (rice, corn, wheat, bean, and potato) decreased by 21%. The area of fruits and vegetables increased from 3.36×105 hm2 to 1.05×106 hm2, and their proportion increased by 20%. ② Nearly 55% of fertilizers had been consumed by vegetable (37%) and citrus production systems, and 11%, 12%, and 12% of fertilizers were consumed by rice, corn, and potato, respectively. ③ The total fertilizer reduction of the Chongqing planting industry could reach up to 1.69×105 tons during the period of "the 14th Five-Year Plan," with a fertilizer reduction potential of 18.6%. The fertilizer reduction potential (reduction amount) of rice, corn, citrus, and vegetables would reach 0.3% (2.9×102 tons), 12% (1.45×104 tons), 21% (3.65×104 tons), and 30% (1.18×105 tons), respectively. On the other hand, the rape system was insufficient in phosphorus potassium fertilizers, and the corn tended to be insufficient in potash fertilizer. ④ The current production level was low, and the nitrogen loss, greenhouse gas emissions, and eutrophication potential in the planting industry of Chongqing reached 1.81×105 tons (N), 1.43×107 tons (CO2-eq), and 1.74×105 tons (PO4-eq). With the increase in the realization degree of the crop quota standard (60%-100%), the reactive nitrogen loss, greenhouse gas emissions, and eutrophication potential decreased by 14.9%-24.9%, 10.1%-16.7%, and 13.8%-23%, respectively. The structure of the planting industry in Chongqing significantly changed, the total fertilizer consumption in Chongqing tended to decline gradually, and the fertilization intensity of commercial crops stayed at a high level. The agricultural fertilizer reduction potential and the reactive nitrogen and greenhouse gas emission reduction potential were large, especially for citrus and vegetable production systems. However, it is also necessary to pay attention to insufficient corn potash fertilizer and rape phosphorus potassium fertilizer investment and carry out collaborative promotion of fertilizer reduction.

Fires and fire risk perception predictors on Finnish farms

ABSTRACT The physical and operational farm environment has become more complex, challenging risk management. This study aimed to identify the number and typical features of farm fires and the factors connected to farmers’ assessments of fire risk. The data comprised a subset extracted from the national accident database of the Finnish rescue services from 2000 to 2021 (3,989 farm fire alarm calls) and farm survey data collected in the spring of 2021 (506 valid responses). The descriptive analysis of the fire incident data showed that the most typical fire sites on farms were dairy cattle buildings, grain dryers, and heating plants. Most farmers (83.4%) assessed the probability of fire as intermediate or high. The Bayesian machine learning approach used to analyse the survey data suggested the control of malfunctions, failures of machinery and equipment, and educational efforts were key elements in fire risk management.
