Optimal nutrient management is crucial for ensuring food security and agricultural sustainability. While technological innovation in nutrient management has been emphasized, the widespread adoption of such technologies remains a significant challenge, particularly in smallholder farming economies. This study presents a case of farmer-participation nutrient management (FPNM), where smallholder farmers are engaged through dialogue and their feedback is integrated into technology optimization and implementation strategies. A multi-site experiment was conducted on 71 fields, where 36 fields were treated with farmer’s customary nutrient management (FCNM) and FPNM, while the remaining 35 fields received only FCNM. The results showed that compared to FCNM, the FPNM increased grain yield by 10.9% and reduced chemical fertilizer inputs by 24.7%, including nitrogen (N) fertilizer by 10%, phosphate (P) fertilizer by 21%, and potassium (K) fertilizer by 25%. The fertilizer cost was reduced by 15.6% and the net income increased by 14.5% under FPNM. Additionally, fertilizer use efficiency increased by 17.1% for N, 37.5% for P, and 33.7% for K. These improvements were primarily achieved through farmers modifying their fertilizer formulas and increasing the application of organic fertilizer. Importantly, the participation-based management approach was particularly valuable as it effectively incorporated farmers’ management practices and acceptance willingness, making sustainable nutrient management techniques highly applicable in regions with widespread smallholder farming operations.

The paper applies the farm accountancy data network (FADN) approach to conduct a comparison analysis of the revenue of EU fruit producers. The study constitutes a significant contribution to the requisite development of more accurate metrics and appropriate approaches, which are necessary for assessing the economic success of EU fruit production in the principal sector of EU agriculture. The metrics used to measure the economic success in fruit production include farm net value added (FNVA), farm net income (FNI), annual working unit (AWU) of FNVA, and farm family income (FFI/FWU). An agricultural farm’s overall productivity can be determined by dividing its entire output (production) by the inputs employed in its operations, such as specific expenses and intermediate consumption. The FADN approach, which tracks the increase in agricultural revenue and assesses the effects of European policies on the agricultural sector, improves monitoring and meeting of performance goals. Finding economic, technological, and other aspects that will improve agricultural farms’ businesses and, by extension, agriculture as a whole will require applying an appropriate methodological approach to portray the actual situation and results of these farms.

The dairy sector is the second largest agricultural sector in the EU and Lithuania. It faces economic challenges (price volatility, farm consolidation and downsizing, etc.), but its importance outstrips other agricultural sectors (combining agro-systems and providing valuable food products for people). The aim of the study is to identify the vulnerabilities of dairy farms and to consider how to improve their performance after analysis of dairy farms in dairy exporting EU countries. As the problem of the study is complex, a set of indicators was analysed, including farm size, milk yield per cow, number of cows per annual work unit (AWU), milk production per fodder area, feed autonomy, milk price, total operating costs, depreciation, farm net value added per AWU, milk production per capita, and GDP at current prices per capita. The analysis was carried out using data from the Farm Accountancy Data Network (FADN) for 2017–2019. As Lithuania’s dairy sector is export-oriented, EU countries with more than 100% milk self–sufficiency (18 countries in total) were chosen for the comparison. The multi-criteria decision-making methods (MCDM) were used for the study. The multi-criteria evaluation revealed that countries that are leaders in dairy exports obtained the best values of dairy farm performance. These countries (Denmark, Netherlands, Ireland, and Belgium) have the highest farm size, production scale, productivity, and income indicators. While Slovenian, Latvian, and Lithuanian dairy farms performed poorly in terms of productivity and economic indicators, these countries achieve competitiveness in the dairy sector through lower milk prices, higher utilisation of own resources, and higher levels of public support.

Beekeeping faces several challenges, such as the Varroa mite. Few studies have measured the economic performance of farms in relation to the practices used for Varroa control. Our study analyzed various biotechniques (total brood removal, TBR; queen caging, QC; royal cell insertion, CI) and other methods (chemical treatments, CT; thymol use, THY) adopted by Italian beekeepers to show whether the adoption of biotechniques leads to farm profitability or a necessary trade-off between sustainability and profitability. Beekeepers were interviewed about the methods and operations conducted on their farms. The net incomes (NIs) of the farms were calculated and inter- and intrafarm comparisons were performed. A detailed schema of each practice was designed. The net income derived from TBR was the highest in eight out of the nine case studies, followed by CI and then QC. The NI calculated for farms using CT was lower than that for farms using other methods in two of the case studies. We also analyzed different biotechniques applied by the same farm and found that the NI resulting from TBR was higher than that achieved from the use of QC and CI. Our study suggests that use of biotechniques represents a long-term sustainable solution for reducing the level of Varroa infestation, which affects farm net income. Full article

Like most crops, sugarcane needs to be kept upright until it is harvested. The lodging of sugarcane has significant negative effects on the cane yield and sugar content of sugarcane. To keep sugarcane upright, earthing up is an essential in the cultural part of the operation. In Bangladesh, most of the sugarcane cultivation operations, including earthing-up, are generally performed in a traditional manual method which increases the production costs as well as reduces the income of sugarcane growers. Therefore, a cost-effective two-wheeled tractor (2WT)-mounted earthing-up machine was developed at the Bangladesh Sugarcrop Research Institute (BSRI), Pabna, to reduce drudgery and the cost of sugarcane production. Field tests were conducted in an experimental sugarcane field at BSRI and technical and economic performances of the developed earthing-up machine were also carried out based on the field test. The average effective field capacity and field efficiency of the earthing-up machine were found to be 0.16 ha/h and 77.41%, respectively. The 2WT-driven earthing-up machine was not found to be economically viable when it was used only for earthing-up operations. However, when the 2WT was used as the main driver for other activities, including earthing-up operation, the earthing-up machine became economically beneficial with net cash flow (NCF), net present value (NPV), internal rate of return (IRR), benefit–cost ratio (BCR), and payback period (PP) of BDT 148,497/ha, BDT 23,184, 3%, 3.81:1, and approximately 1 year, respectively. On the contrary, considering the cost of only earthing-up tool without 2WT, it was found to be economically beneficial with NCF, NPV, IRR, BCR, and PP of BDT 16,428/ha, BDT 3053, 4.7%, 2.71:1, and approximately 2 years, respectively. In Bangladesh, 2WT is commonly used for versatile farming purposes. Therefore, the versatile use of 2WT as a prime mover for other machines, including the earthing-up machine, can make earthing-up machine economically viable and beneficial for sugarcane growers in Bangladesh.

This study uses the data obtained from 63 broiler farms engaged in contract farming in Akhisar, Turkey. The average feed conversion ratio in the broiler farms is 1.75, the average live weight 2.25 kg, and the mean market age 38.9 days. The feed conversion rate and the income generated are highly correlated (r = −0.76). The production index is 313.4. According to this production index value, 47.6% of the enterprises are below the average production index. It is highest when the marketing age is greater than 38 days, less than and equal to 40. In other words, it is the optimum market age range where carcass yield is at maximum. The average mortality rate is 4.68%. In 52.4% of the enterprises, the mortality rate is above 5%. There is a low level of correlation between the mortality rate and income (r = −0.26). In broiler farming, mortality rate, and feed conversion ratio are factors that directly affect the success and income of the breeder. In broiler farming, the heating cost has the largest share of the total cost, followed by the litter cost. They are followed by labor, electricity, and pesticide costs. Variable costs account for three-quarters of the total operating costs. The farms have a mean gross value of production of $23.797 per m² and $1.400 per broiler in a breeding period. The profit margin is 0.572 $/kg per broiler. The mean enterprise net income in the breeding period is $9.197 per m² and $0.541 per broiler. These findings suggest that broiler farming is a profitable venture. Full article

This paper has developed an operation and maintenance (O&M) model for projected 20 MW tidal stream farm case studies at two sites in the northeast Atlantic in France and at EMEC’s Fall of Warness site in the UK. The annual energy production, number of incidents, and downtimes of the farms for corrective and planned (preventive) maintenance strategies are estimated using Monte Carlo simulations that vary weather windows, repair vessel availabilities, and mean annual failure rates modelled by Weibull distributions. The trade-offs between the mean annual failure rates, time availability, O&M costs, and energy income minus the variable O&M costs were analysed. For all scenarios, a 5-year planned maintenance strategy could considerably decrease the mean annual failure rates by 37% at both sites and increase the net energy income. Based on a detailed sensitivity analysis, the study has suggested a simple decision-making method that examines how the variation in the mean annual failure rate and changes in spare-part costs would reduce the effectiveness of a preventive maintenance strategy. This work provides insights into the most important parameters that affect the O&M cost of tidal stream turbines and their effect on tidal energy management. The output of the study will contribute to decision-making concerning maintenance strategies. Full article

The agrarian communities of South Asia are dominated by small and marginal farmers (<2.0 ha operational holdings) and are confronted with manifold challenges of lower productivity, income, and resource degradation. For optimized and efficient resource use, a shift from business as usual towards green economy is imperative. Therefore, a study to address these challenges, through integrating diverse crops and allied enterprises under an integrated farming system (IFS) model was carried out. We hypothesized that a standardized IFS model with appropriate location-specific modules will have higher system output, income, and lesser environmental footprints. Vegetable cultivation (VC), protected vegetable cultivation (PVC), field crops (FC), mushroom production (MP), and beekeeping (BK) were evaluated under the IFS model, with objectives to optimize the coherent use of available farm resources with enhancing system productivity and profitability. Among the FC module, the system productivity increased from 21–247% of different cropping systems, over the predominant rice–wheat system (RWS). The integration of different components, viz., VP + PVC + FC + AHS + MP + BK + VC in M₁₀ resulted in achieving the maximum water productivity (6.72 kg/m³), energy productivity (1.50 kg/MJ), net return (9446 USD/ha), employment opportunities (792 man-days), sustainable livelihood index (70.2%), and nutrient cycling (138.12, 67.9, and 381.6 kg/ha of nitrogen, phosphorus, and potassium, respectively). These findings can be a scientific basis for the optimization and sustainable management of natural resources under different modules of IFS for the less-endowed small and marginal farmers.

Rice production in the Central Plains of Thailand plays a key role in the country’s food security. However, the overuse of inputs coupled with the rising production costs are making it increasingly difficult for smallholder rice farming to remain economically and environmentally sustainable. Replicated production-scale field trials of Cost Reduction Operating Principles (CROP)—Thailand’s national package of best management practices for rice production—were established in tandem with laser land leveling (LLL), mechanical drum seeder, and the application of two biofertilizer products (i.e., PGPR II, that contains Azospirillum brasilense Sp. TS29 and Burkholderia vietnamiensis S45; and LDD #12, that contains Azotobacter tropicalis, Burkholderia unamae and Bacillus subtilis) and compared with farmer’s practices (FP). Performance indicators (PI) promoted by the Sustainable Rice Platform (SRP) were used to assess economic and environmental indicators. CROP + PGPR had significantly higher net income (79%) and nitrogen-use efficiency (57%) compared with FP. Pesticide use (28%), seed (60%), inorganic fertilizer N (41%) and total production costs (19%) were reduced in all CROP treatments compared with FP. These results demonstrate that the application of CROP, LLL, mechanical drum seeder, and biofertilizers can substantially improve the economic and environmental sustainability of rice production in the Central Plains of Thailand.

The concept of a bioeconomy can be an opportunity for agricultural and rural development. The objective of this research is to identify groups of family farms which are able to implement the principles of this new development model based on a bioeconomy and to reduce operating costs, especially energy. The time scope of this study covers the period 2004–2020. The data source is the Farm Accountancy Data Network. On the basis of the values of output, family farm income, cash flow, net investment and total inputs (including energy costs), the classes of family farms are indicated. The ranking is based on geographical criteria and the results of panel data models with fixed effects which measure the relationship between energy costs and production, income, cash flow and net investment according to the economic size of the family farm. The results obtained are discussed within the framework of recommendations of the European Commission. Full article

The sloping land conversion program (SLCP) is one of the most important payment for ecosystem services (PESs) in the world, as direct stakeholders and the final implementers of the SLCP, farmers’ willingness to maintain the achievements is the basis for the consolidation and sustainable operation of the SLCP. Based on a survey of 975 farmers in Hunan Province, Gansu Province, and the Ningxia Hui Autonomous Region, this study used the elastic net model to accurately select the influencing factors of farmers’ willingness to maintain the SLCP and the logit model to measure these factors. Finally, combined with the interpretative structural model (ISM), we further analyzed the hierarchical structure of each significant influencing factor. The main results are as follows. Firstly, off-farm employment, whether the head of the household is a village cadre, labor number, land area, income level, subjective norms from the organization, altruistic rationality, active ability, and policy perception had significant and positive impacts on farmers’ willingness to maintain the SLCP. In contrast, whether the head of the household is an ethnic minority and the expiration of the SLCP subsidy had significant and negative impacts on farmers’ willingness to maintain the SLCP. Secondly, the factors affecting farmers’ willingness to maintain the SLCP are at different levels, being both independent and interrelated. Among them, the deep-rooted factors are whether the head of the household is an ethnic minority, the expiration of the SLCP subsidy, the labor number, and whether the head of the household is a village cadre. Based on the above results, government departments should broaden the income channels of farmers in ethnic minority areas, strengthen the publicity to maintain the SLCP in ethnic minority areas, and improve the SLCP’s follow-up policy to enhance the farmers’ willingness to maintain the SLCP and ensure the program’s sustainability.

This paper analyses the production availability and the associated maintenance costs of an offshore wind turbine with a horizontal axis configuration using Petri Nets modelling with Monte Carlo Simulation. For this purpose, different features are implemented: the reliability and maintainability characteristics of the components; the logistics of the production and maintenance operations, including different types of vessels, the mobilization time, costs and weather window. The maintenance strategies consist of corrective maintenance and age-based imperfect preventive maintenance that depends on the components’ age and age reduction ratio. Thereby, to increase the operating income and to reduce the costs associated with the operation and maintenance activities, the optimal parameters of the age-based preventive maintenance are estimated. As a case study, a generic offshore wind turbine that operates at the Viana do Castelo wind farm in Portugal is adopted. The wind farm is located 18 km off the shore. The turbine’s total exploration life is 25 years. Full article

New Zealand hill country sheep and beef farms contain land of various slope classes. The steepest slopes have the lowest pasture productivity and livestock carrying capacity and are the most vulnerable to soil mass movements. A potential management option for these areas of a farm is the planting of native shrubs which are browsable and provide erosion control, biodiversity, and a source of carbon credits. A bioeconomic whole farm model was developed by adding a native shrub sub-model to an existing hill country sheep and beef enterprise model to assess the impacts on feed supply, flock dynamics, and farm economics of converting 10% (56.4 hectares) of the entire farm, focusing on the steep slope areas, to native shrubs over a 50-year period. Two native shrub planting rates of 10% and 20% per year of the allocated area were compared to the status quo of no (0%) native shrub plantings. Mean annual feed supply dropped by 6.6% and 7.1% causing a reduction in flock size by 10.9% and 11.6% for the 10% and 20% planting rates, respectively, relative to 0% native shrub over the 50 years. Native shrub expenses exceeded carbon income for both planting rates and, together with reduced income from sheep flock, resulted in lower mean annual discounted total sheep enterprise cash operating surplus for the 10% (New Zealand Dollar (NZD) 20,522) and 20% (NZD 19,532) planting scenarios compared to 0% native shrubs (NZD 22,270). All planting scenarios had positive Net Present Value (NPV) and was highest for the 0% native shrubs compared to planting rates. Break-even carbon price was higher than the modelled carbon price (NZD 32/ New Zealand Emission Unit (NZU)) for both planting rates. Combined, this data indicates planting native shrubs on 10% of the farm at the modelled planting rates and carbon price would result in a reduction in farm sheep enterprise income. It can be concluded from the study that a higher carbon price above the break-even can make native shrubs attractive in the farming system. Full article

Water is the most important resource; it is utilized largely in agricultural production and is fundamental to ensuring global food security. This study aims to assess sustainable water management interventions and their impact on the farm economy. To increase water productivity, the most important adaptations that have been proposed are high-efficiency irrigation systems, drought-resistant varieties, the substitution of water-intensive crops with less water-demanding crops, the mulching of soil, zero tillage, and all on-farm operations that can save water, especially ground water. The recent analysis utilized farm survey data from 469 representative farmers along with secondary statistics. The data were collected via a multi-stage sampling technique to ensure the availability of representative farm populations based on a comprehensive site selection criterion. The TOA-MD model estimates the adoption rate of a proposed adaptation based on net farm returns. The impact of high-efficiency irrigation systems and the substitution of high delta crops for low delta crops had a positive impact on net farm returns and per capita income, and a negative impact on farm poverty in the study area. It is recommended that policymakers consult farmer representatives about agricultural and water-related issues so that all the policies can be implemented properly. Full article

Meeting greenhouse gas (GHG) reduction targets will require a significant increase in electricity production from sustainable and renewable sources such as solar energy. Farmers have recognized this need as a chance to increase the profitability of their farms by allocating farmland to solar power production. However, the shift from agriculture to power production has many tradeoffs, arising primarily from alternative land uses and other means of production. This paper models the farmers’ decision as a constrained profit maximization problem, subject to the amount of land owned by the farmers, who have to allocate it between agriculture and solar power fields, while considering factors affecting production costs. The farmers’ problem is nested in the social welfare maximization problem, which includes additional factors such as ecological and aesthetical values of the competing land uses. Empirical analysis using data from a solar field operating in Israel shows that landowners will choose to have solar power production on their land unless agricultural production generates an unusually high net income. Adding the values of non-market services provided by agricultural land does not change this result. The consideration of the reduction in GHG emissions further increases the social welfare from solar fields. Full article
