Stochastic partial budget analysis of strategies to reduce the prevalence of lung lesions in finishing pigs at slaughter.

Ante- and post-mortem inspections of food-producing animals at slaughter are mandatory activities carried out in many countries to ensure public health, animal health, and meat quality. In finishing pigs, lung lesions are the most frequent defects found in meat inspections. It is possible to implement managerial strategies on-farm to reduce the occurrence and spread of respiratory diseases, but such strategies come with additional costs that could impede implementation. This study assessed the economic impact of two strategies aimed at reducing the prevalence of lung lesions in finishing pigs at slaughter by improving the health conditions of the animals during the production cycle. First, a farrow-to-finish pig farm with 355 sows was modeled based on the current standard practice for finishing pig production in Sweden, using economic data, meat inspection data and biological variables from the literature and expert opinions. A partial budget analysis was then performed in which the baseline farm was compared with two hypothetical strategies aimed at reducing the occurrence and spread of respiratory diseases during pig production: (S1) avoiding mixing of litters after weaning and (S2) keeping purchased pregnant gilts separated from sows during gestation, farrowing and lactation. Both these strategies intended to reduce the occurrence of respiratory disease in finishing pigs at slaughter gave an average gain in annual net income (33,805 SEK in S1 and 173,160 SEK in S2, equal to 3,146€ and 16,113€, respectively, at the time of analysis), indicating that both were economically sustainable under the assumed conditions. The impact analysis of the two strategies revealed that the reduced prevalence of lung lesions when adopting one of the strategies was the most influential factor in net benefit change on the farm. Overall, the results suggest that with the increasing prevalence of lung lesions in Swedish pig production (as also observed worldwide in recent years), adopting an effective strategy to decrease respiratory infections will become more relevant and economically beneficial.

Characterizing country-specific human and ecosystem health impact and damage cost of agricultural pesticides: the case for Thailand

PurposeExisting emission and toxicity characterization models in life cycle assessment are currently not suitable for assessing pesticide-related impacts of crop cultivation in tropical regions. This study aims to parameterize the scientific consensus model USEtox for Thai environments to derive toxicity characterization factors of pesticide emissions from agricultural systems in Thailand. Potential human toxicity and ecotoxicity impacts and related damage costs of pesticides used on nine crops cultivated in Thailand are quantified.MethodsConsidering country-specific conditions, USEtox was adapted by applying the landscape and consumption parameters specific to Thailand. Related Thai-specific characterization factors of identified pesticides used in Thai agriculture were quantified. Four emission inventory models were applied to determine pesticide emission fractions in different environmental compartments. The consistent combination of pesticide emission mass and associated characterization factors yielded potential toxicity impact scores. Pesticide impact-related damage costs (external costs) on human health and ecosystem quality were quantified using valuation factors for Thailand. The crops with the highest total damage costs were selected and compared with the annual net incomes of the respective crop production systems.Results and discussionPesticide toxicity impacts assessed by using Thai-specific factors were different from the use of global average factors ranging from 1 to 169% (human toxicity) and from 0.1 to 3587% (ecotoxicity). Our results indicated the variability in impact scores influenced by emission modeling choices. Following PestLCI consensus emission estimation model, mango cultivation showed the highest human toxicity impacts of 0.07 DALY/ha, resulting in high human health damage costs mainly caused by Propineb (93%). Rice cultivation with a dry direct-seeded system exhibited the highest ecotoxicity impacts (3934 PDF m3 day/ha) and associated damage costs mainly caused by Oxadiazon (92%). Pesticides used in cultivation of nine crops resulted in total damage costs of 7188 and 3.01 million THB/crop-year for human health and ecotoxicity, respectively. Mango and rice production accounted for 70% and 17% of the total damage costs, which were 36% and 20% of the respective crops’ annual net income.ConclusionsOur study illustrates the ranking of pesticides applied throughout the crop calendar causing toxicological impact and related damage costs on human health and ecosystem quality. This helps identify crops and the main contributors to pesticide-related toxicity impacts in Thailand. Our study highlights the need for proper emission quantification and for the use of characterization factors locally parameterized to increase accuracy. Our results will be useful for future improvement toward more sustainable pesticide use.Graphical abstract

Air pollution and perception-based averting behaviour in the Jinchuan mining area, China.

This paper presents a simultaneous equation, knowledge and perception-based averting behavior model of health risk caused by air pollution, with application to the Jinchuan mining area, China. Three types of averting behavior are distinguished: (a) purchases of purifying equipment, plants, or masks; (b) purchases of preventive or curing medication or food; and (c) adjustment of daily outdoor activities. Two types of perceived health risk are distinguished: (a) risk due to the intensity of exposure and (b) risk caused by the hazardousness of pollutants. The estimations show that an increase in perceived air pollution of two or more days a week leads to a restriction of outdoor activities of approximately 90 min per person per week. Another result is that the average annual household expenditure on air filters, foods, or medicines is 206.25 CNY (US$ 31.73) to prevent the hazardousness of air pollution. The total willingness to pay for air quality improvement is 2.95% of annual net household income. Because air quality improving investments can only be implemented in the medium or long run, daily disclosure of air quality is an adequate short-run policy handle to assist residents to take the right kind and level of risk-reducing actions.

Training at farmers training centers and its impact on crop productivity and households’ income in Ethiopia: A propensity score matching (PSM) analysis

The creation and expansion of training and extension networks for rural households are indispensable to develop and improve skills and to increase productivity and income-generating capabilities. In this line, Ethiopia has established farmers/pastoralists training centers (F/PTCs) since 2002 aimed at providing a multitude of services to farmers at the grassroots level. One of these services is the provision of training. The purpose of this study, therefore, is to assess the impact of training on crop productivity and households’ income in the study area. Cross-sectional data were collected from April to June 2020 from 362 and 373 sample respondents involved in wheat (Triticum aestivum) and maize (Zea mays) production in the 2018/19 main cropping season, respectively. The mixed-methods research approach was used for the study. The quantitative data were collected through a semi-structured interview schedule from the respondents. The qualitative data were also collected by interviewing key informants and conducting focus group discussions. The propensity score matching (PSM) model was applied to analyze the impact of training on the aforesaid outcome variables. About 87% of the sample households were engaged in both wheat and maize production in the study area. The PSM results found indicate that trainees increased their wheat and maize yield by 860.16 (26.66%) and 301.56 (10.10%) kg ha-1, respectively. They also earned a net annual income of 7,490 (19.64%) Ethiopian birr ha-1 from wheat production.

Performance evaluation of a supercritical water oxidation cogeneration system using hydrogen peroxide as oxidant

Supercritical water oxidation (SCWO) is widely used for organic waste for its fast degradation rate and higher efficiency. As a kind of wastewater treatment system with high energy density, its energy utilization of SCWO is a hot issue of great concern. In this paper, 35 % concentration of hydrogen peroxide was employed as the oxidation medium, combined with the organic Rankine cycle (ORC), a hybrid system based on the SCWO system was constructed. From the perspective of efficient energy utilization within the SCWO system, parameter sensitivity analysis, exergy and economic analyses were performed for the proposed system. It can be found from the results that when operated with organic wastewater mass flow rate of 5020 kg/h (12% w.t.), the obtained net power of the system was 668.06 kW, the heat generated for heat consumer was 2918.20 kW. The electrical and thermal efficiencies of the system were 14.96% and 65.34%, the cogeneration efficiency was 62.28% and exergy efficiencies were 34.54%, respectively. Exergy analysis results showed that the four components that consumed the most exergy destruction in the whole system were: heat exchanger for recovering waste heat from the oxidation reaction solution to the heat user, primary preheater for heating organic wastewater, and primary preheater for heating hydrogen peroxide, and the reactor which accounting for 32.05%, 17.85%, 14.87% and 13.99% of the total exergy destruction of the system, respectively. Economic analysis results showed that the annual net income of the system was 7490.37 k$/year. The system with compressed air as the oxidation medium was used to compare with the proposed system. The results showed that the proposed system with higher electrical efficiency, heat efficiency as well as revenue from electricity and hot water.

The Forage Plantation Program between Desertification Mitigation and Livestock Feeding: An Economic Analysis

To combat desertification and land degradation in arid and semi-arid zones, the government has adopted an approach of rehabilitation of pasturelands through forage plantations. This program was launched at the beginning of the 1990s and, to date, there has been no global or national study on the sustainability of the program, particularly its economic profitability. Our work’s principal objective was to perform an economic analysis of the forage plantation program across the different periods since the creation of the program until the year 2020, focusing on the economic evaluation parameters of the projects, such as mean annual net income, net present value, annuity of the net present value, profitability index and payback period, based on the data collected from the official institutions. The results showed that the forage plantation program significantly contributes to sustainable development in steppe areas.

Evaluation of crop productivity, water and nitrogen use, and carbon footprint of summer peanut ‐ winter wheat cropping systems in the North China Plain

AbstractThe introduction of legumes into the cropping system has been considered as an effective and alternative way to reduce nitrogen (N) input and greenhouse gas (GHG) emission, and boost system productivity. However, the productivity, water and N use, and carbon emission of legume‐based cropping systems in the North China Plain were not well‐documented. Here, a 2‐year field experiment was conducted to compare the yield, water and N use, and carbon footprint (CF) of summer peanut–winter wheat (PW) and summer maize–winter wheat (MW) cropping systems. Results showed that the experimental year significantly affected system productivity and water use efficiency of PW and MW. PW increased annual equivalent yield and water consumption by 10.1% and 12.9% in the first year (p < 0.05), compared with MW. Yet, PW decreased annual net income by 8.6% on average during the two experimental years. PW lowered annual N input by 12.1% compared with MW; however, no significant difference in apparent N use efficiency was found between PW and MW. Moreover, PW decreased its annual CF by 13.0%, which was attributed to the lower indirect GHGs emission from N input of summer peanut. In summary, PW showed considerable potential in reducing N fertilizer input and CF, with acceptable economic loss and water consumption in the North China Plain.

Taxation of Incomes from Independent Activities Obtained by Tutoring Teachers

The provision of services by teachers in private, as tutors, fiscally fits in the category of income from independent activities, and the taxpayers who carry out these activities must authorize themselves in accordance with the legal provisions in force and to fulfil their declaratory and payment obligations. The tax that teachers who offer tutoring in private must pay to the state budget is determined by reference to the annual net income, either in real system, based on the accounting data, or according to income rules. In certain situations, there is an obligation to pay social contributions. For the amounts collected in cash or by card, the tutoring teachers are obliged to issue fiscal receipts, therefore to have a cash register with an electronic journal. Persons intending to achieve or who have already achieved individual income from the provision of services representing tutoring fall within the scope of VAT exemption.

Resource optimisation in aquaponics facility via process monitoring and graph-theoretical approach

Energy efficiency and economic viability are the often-quoted issues in aquaponic farming. This work aims to (i) identify process technologies and technical measures which would enhance the profitability of aquaponics business while conserving energy and other resources, and (ii) to validate the determined optimal measures on the testing aquaponics farm. The process network synthesis technique was used to search for an optimal process pathway while the image processing technique was applied to automatically monitor the growth rate of produce since it is the main revenue stream in aquaponics. With the aid of P-graph method, the optimal feasible structure has 9 times higher annual net income than that of the existing process. This optimal solution includes the integration of electrical heat pump, biogas system, and utilizes black solider fly (BSF) facility to produce fish feed. Additional light energy savings were achieved by practical installation of reflective foils which improved 16.88% of Photosynthetic photon flux density (PPFD) on growth beds. These measures can help the aquaponics farms to become more competitive and to decrease their ecological footprint.

Dynamics and Determinants of the Grain Yield Gap in Major Grain-Producing Areas: A Case Study in Hunan Province, China.

Understanding the dynamics of the grain yield gap (YGAP) and its causative factors is essential for optimizing the layout of grain production and addressing the food crisis, especially in countries with a huge population and less cultivated land, such as China. In the study, a spatial analysis- and machine learning-based framework for YGAP analysis was developed, taking Hunan Province, China, as an application. The results showed that the average YGAP in Hunan Province gradually narrowed from 1990 to 2018, and the YGAPs narrowed in 116 counties. Of which, 26 counties narrowed by more than 4 t ha−1, 58 counties narrowed from 2–4 t ha−1, and 32 counties narrowed within 2 t ha−1. Additionally, we found that the GDP per capita (GDPPC), sunshine hours (SH), per capita annual net income of farmers (PCAI), and rural electricity consumption (REC) play a key role in YGAP change, and the importance of human investment to the YGAP decreased, while socioeconomic environment became the dominant factor that influenced grain production. Comprehensively, the relatively great potential for grain yield growth was generated in sixty-four counties, which are mainly located in the northern, central, and southern Hunan. The findings suggest that it is necessary to consider the trends of economic development in rural areas and population migration in agricultural management. This work provides insights into yield gap dynamics and may contribute to sustainable agricultural management in Hunan Province, China, and other similar regions.

Behavioural Determinants of Functionality of Farmer Producer Organisations in Punjab

Small and marginal farming communities of Indian agriculture account for more than 85%of the total farming households. They face the challenges of land fragmentation, high costof inputs and inability to market their produce efficiently. To tackle these challenges, policymakers came up with the model of farmers’ mutual cooperation through Farmer ProducerOrganisations (FPOs). This study conducted in Punjab analyses the behavioural factorsresponsible for functionality of FPOs. A random selection of 150 members from 5 functionaland 5 non-functional FPOs (i.e., 15 respondents from each selected FPO) was made andthe respondents were interviewed personally. The findings revealed that the members(including management) of the functional FPOs had higher risk bearing capacity, greatereconomic motivation and more innovativeness as compared to the respondents from non-functional FPOs. Similarly, respondents from functional FPOs were socially, economicallyand managerially more empowered than the non-functional FPOs. Business skills of themembers, including the managerial members, of functional FPOs were also better ascompared to those from the non-functional FPOs. Regression estimates revealed that thefunctionality, better academic qualification, bigger land holding and joint family systemwere responsible for the higher net annual income of the respondents.

Financial and Socio-economic Study of Modular Pyrolysis Facilities as Waste-to-Energy Technology: a Case Study in Metropolitan Manila, Philippines

Industrial, medical, and electronic residual wastes can potentially be an important source of energy with the use of waste-to-energy (WtE) conversion technology. In Metropolitan Manila, Philippines, about 144,000 kg/d of residual wastes were being generated by the hospitals, industrial sectors, and electronic companies. Hence, imploring high potential benefits can be achieved through utilizing these wastes as feedstock for any WtE conversion facility. A technical and financial costing was performed to evaluate the feasibility of putting up a conventional pyrolysis system in Metropolitan Manila. Various modular-type scenarios of a pyrolysis system in the WtE facility were identified based on the geographical attributes of the sectoral residual wastes generators. Results showed that a 10 tons/d pyrolysis plant facility, with Brayton power set-up, can eventually produce 800 kW and generate an annual net income of PHP 83.63 M after a 2-yr breakeven period. In addition, this facility can accommodate at most 11 tons/d of residual wastes for processing. In contrast, a smaller footprint of pyrolysis-Brayton set-up consisting of three tons per day, with 1,000 kg of daily wastes and a power generation of 65 kW, can potentially produce a net income of PHP 18.06 M following a 3-yr breakeven period. The WtE business models of putting up conventional pyrolysis facilities, by presenting both the maximum and minimum scenarios in terms of plant capacity and income when intended for operation and adoption, were computed to be feasible.

Energy Storage Economic Optimization Scheduling Method for Multi-Scene Demand of Peak and Frequency Modulation

Energy storage (ES) only contributes to a single-scene (peak or frequency modulation (FM)) control of the power grid, resulting in low utilization rate and high economic cost. Herein, a coordinated control method of peak modulation and FM based on the state of ES under different time scales is proposed. Firstly, for monotone peak and FM control scenarios, the ES configuration and scheduling model is constructed with the goal of maximizing net profit. Secondly, to further improve the ES utilization rate and optimize the operating cost of ES, a cooperative control method of peak modulation and FM is proposed. This method can realize the switch between peak modulation and FM control of ES and improve the ES utilization rate and system economy. Finally, the simulation results show that, compared with that of mono-peak and single-FM control, the ES efficiency of the peak-FM multiscenario optimization scheduling method is improved by 16.25% and 37.29%, respectively. The annual net income is increased by €28,021.50, the investment recovery period is shortened by 0.27 years, and the ES configuration economy is effectively improved.

Efficient Fishing Method to Control the Population of Rice Eel, Monopterus albus (Synbranchidae) in Rice Fields in Cagayan Valley, Philippines

Rice eel (Monopterus albus) was introduced in the Philippines in 1905 as an aquaculture species without a thorough evaluation of its possible negative impact on the environment. In Cagayan Valley Region, it is being considered as a pest due to the economic loss it brought to farmers as it bore holes on the dikes, draining the water from the rice field, thus, contributing to the additional expense of the farmers. However, from the economic point of view, the species offered great potential as an export commodity due to its broad export market in East Asian countries. Hence, this study was conducted to determine the most efficient and effective method of controlling the proliferation of rice eel in rice fields in the Cagayan Valley region while preserving its integrity as an export commodity. Twelve (12) municipalities were chosen as the study sites based on validated reports of the high occurrence of rice eel. Three fishing methods, namely, fish trap (FT), hook and line (HL), and electrofishing (EF) gadget, were utilized. These gears were set during the dry and wet seasons. Catch and catch per unit effort (CPUE) were used to determine gear efficiency, while monetary values, net income, and ROI were used to assess the profitability of the gears. Results showed that electrofishing gadgets exhibit greater efficiency among the three fishing gears. The EF gadget also has the highest CPUE (4 individuals) per hour while only around 0–1 per hour for FT and HL. Seasonality does not affect the efficiency of the three fishing gears. Also, there is no significant interaction between seasons and fishing gears (p = 0.525). Computed annual net income and return on investment (ROI) is also greater using EF (PHP 407,630.40/ha/year with 569% ROI) compared to HL and FT (net incomes of PHP 113,244.68/ha/year and PHP 161,618.99/ha/year, and 261% and 309% ROI, respectively). However, the use of EF as a control measure should entail restrictions such that only within rice farm areas and not in open waters and only after harvest or before planting with issued EF licenses and permits from BFAR and local ordinances. Higher penalties should also be imposed for illegal use of EF such as use in open waters. As an alternative to EF, a combination of FT and HL with modifications or more environment-friendly fishing gears can be explored to catch and control the rice eel population.

Puhtpuistute hinna- ja kasumiküpsuse empiiriline analüüs Eesti majandusmetsades ning selle võrdlus uuendusraiet lubava vanusega

Abstract The article provides an overview of the results of the maturity age calculations for economically important tree species’ stands in Estonian commercial forests. The maturity by price is determined by a stand’s stumpage value per year of rotation. The maturity by net income (forest rent) is determined by the average annual net income of forest management, which is calculated based on the timber sales revenue, forest management costs and rotation period. The annual land tax and administrative costs have been included in the calculations, as well. The calculated maturity ages are compared with the required rotation ages stated in the Rules of Forest Management. According to the calculations, the maturity age by net income for pine stands in Ia and I site classes is 10…20 years lower than the current rotation age for regeneration felling. The maturity ages for spruce stands coincide with the current rotation ages. The calculated maturity ages by net income for aspen are about ten years higher than the current rotation ages. A comparison of the calculated maturity ages with the current rotation ages shows that these are rather similar.

Multiple pathways towards achieving a living income for different types of smallholder tree-crop commodity farmers

Many sources indicate that smallholder tree-crop commodity farmers are poor, but there is a paucity of data on how many of them are poor and the depth of poverty. The living income concept establishes the net annual income required for a household in a place to afford a decent standard of living. Based on datasets on smallholder cocoa and tea farmers in Ghana, Ivory Coast and Kenya and literature, we conclude that a large proportion of such farmers do not have the potential to earn a living income based on their current situation. Because these farmers typically cultivate small farm sizes and have low capacity to invest and to diversify, there are no silver bullets to move them out of poverty. We present an assessment approach that results in insights into which interventions can be effective in improving the livelihoods of different types of farmers. While it is morally imperative that all households living in poverty are supported to earn a living income, the assessment approach and literature indicate that focussing on short- to medium-term interventions for households with a low likelihood of generating a living income could be: improving food security and health, finding off-farm and alternative employment, and social assistance programmes. In the long term, land governance policies could address land fragmentation and secure rights. Achieving living incomes based on smallholder commodity production requires more discussion and engagement with farmers and their household members and within their communities, coordination between all involved stakeholders, sharing lessons learnt and data.

ASSESSMENT OF THE ROLES OF AGRICULTURAL EXTENSION SERVICES IN IMPROVING THE LIVELIHOOD OF FOOD CROP FARMERS IN KWAYA-KUSAR LOCAL GOVERNMENT AREA OF BORNO STATE, NIGERIA

This study assessed the roles of agricultural extension service in improving the livelihood of food crop farmers in Kwaya-Kusar local government Area of Bono State, Nigeria. Multi-stage random procedure was used to select 120 respondents from the study area. Data collected and administered through the use of structured questionnaires were also analyzed using both descriptive and inferential statistics. The results revealed that many (43.3%) of the respondents were between the ages of 36-40 years. Furthermore, from the findings of multiple regression analysis, age, sex, marital status, annual net income, farm size, household size, educational level and extension per person were significant at P≤0.05 level, respectively, while farming experience and access to credit were significant at P≤0.01 level in that order. It was concluded that male dominated food crop production their by putting the female counterparts at the disadvantage side. The study therefore, recommended that the female respondents should be highly involved or encourage to participate actively in food crop production. Also, on poor government funding toward extension service delivery, government, policy makers and other non-governmental organizations (NGOs) should help the farmers by providing funds to boost their production capacity.

The potential for photovoltaic-powered pumped-hydro systems to reduce emissions, costs, and energy insecurity in rural China

• A micro-PV-PH system is proposed in rural China. • The technical feasibility of a PV-PH installation in rural areas is evaluated. • Techno-economic indicators are used to investigate the potential of the PV-PH system. • This research provides a theoretical foundation for the promotion of the PV-PH system. Homes in rural China often have access to water wells for domestic and agricultural use. Given the significant difference in height between the well water and the roof of the house, such an arrangement could be used as a solar-powered pumped-hydro energy generation system. These systems could both limit increases in carbon emissions from coal-powered electricity while alleviating energy insecurity, while providing significant savings to households. The potential for these systems in rural regions across Shaanxi province is investigated by assessing eight key environmental and socioeconomic indicators. The find is that positive impacts across almost all indicators with generally rapid investment payback periods of 6.4–8.1 years, annual net income increases of 314.2 CNY −541.6 CNY per year per household. This research laid a theoretical foundation for the promotion of PV-PH system in Shaanxi Province.

Integrated use of lime with Mg fertilizer significantly improves the pomelo yield, quality, economic returns and soil physicochemical properties under acidic soil of southern China

Magnesium (Mg) is an essential mineral nutrient for plant growth, and its deficiency in citrus orchards has been widely observed in the acidic soils of southern China. Lime amendments have been proposed as potential solution to mitigate the soil pH and improve the soil quality. Therefore, we evaluated the effects of lime and Mg fertilizer on soil physicochemical properties, nutrients uptake, pomelo quality and yield, and economic benefits in the pomelo production area. For this, a field experiment was conducted during 2017–2019 using three treatment combinations; (i) control with no lime and Mg fertilizer (CK), (ii) Mg fertilizer with no lime (+Mg), and (iii) lime combined with Mg fertilizer (Lime+Mg). We found that Lime+Mg treatment significantly increased pomelo yield by 34.2% and 26.8% in 2018 and 2019, respectively over CK. Economically, Lime+Mg application increased the annual net income by 37.4%. Under Lime+Mg treatment, the concentration of N, K, Ca, and Mg was increased, while Fe and Mn decreased in leaf, peel, and pulp. Lime+Mg application significantly increased the edible rate, and total soluble solids (TSS) by 7.2% and 4.2%, respectively, while decreased the titratable acid (TA) by 11.7% in pomelo. Lime+Mg treatment also raised the soil pH, available N, P, Ca, and Mg concentrations significantly. Our results demonstrate that Lime+Mg incorporation to acidic soils of pomelo orchard alleviates the soil acidification, improves the nutrients availability, yield and fruit quality, and results in more economic benefits.

Analysison the Willingness and InfluencingFactors of the Villagers to Market the Rural Collective Construction Land in Nanhai District of Guangdong Province under the Background of Transformation and Upgrading of Manufacturing Industry

By analyzing the cognition and willingness of the villagers in Nanhai district (a big manufacturing city) of guangdong province to the marketing of the rural collective operating construction land, this paper finds out the key factors of the villagers' response to the marketing of the rural collective operating construction land, and puts forward some suggestions on how to promote the villagers' response to the marketing of the rural collective operating construction land. This paper takes villagers from 7 towns in Nanhai District of Guangdong Province as the investigation objects, and effectively gets questionnaires from 596 villagers by means of random investigation. The research methods of descriptive statistics and Logistic regression model are specifically used.The villagers in Nanhai District of Guangdong Province have a strong willingness to market the rural collective operating construction land, among which 63.42% of the surveyed villagers agree to market the rural collective operating construction land, but 36.58% of the surveyed villagers still have a weak willingness. There are five key factors that affect villagers' willingness to market rural collective operating construction land: villagers' education level, agricultural dependence, annual household net income, expectation of market effect and view of market risk of agricultural land.In order to improve the willingness of the villagers in Nanhai District of Guangdong Province to enter the market of the rural collective operating construction land, the following four measures can be taken to realize it: First, to improve the villagers' education level; Second, reduce the villagers' dependence on agriculture and increase the annual net income of the villagers' families. Thirdly, the demonstration effect of entering the market should be effectively done to improve the villagers' expectation of the effect of entering the market. Fourthly, the education of popularizing the knowledge of entering the market should be strengthened to guide the villagers to correctly understand the institutional nature of entering the market of agricultural land so as to reduce the risk of entering the market of agricultural land.
