This article analyzes the temporal programming of sales for a horticultural marketing company, e.g. a cooperative. The empirical study references the European tomato market, where most of the production is sold through the retail channel dominated by large distribution chains. We study the marketing schedule for an individual company, or even a prominent farmer, using a modified Markowitz model, assuming that his decisions do not affect the balance of market prices. As a result, this model can manage risk and improve decision-making. The data also provide information on the risk borne by marketers depending on their sales calendar, which often depends on their geographic location.

Global climate change is a crucial environmental issue. Worldwide warming is primarily caused by carbon dioxide (CO2) emission levels. Agricultural production is among many economic activities driving CO2 creation and environmental degradation. In this study, we aim to disclose the effect of agricultural production (date production) on the agricultural gross domestic product (AGDP) and the environment (CO2 emissions). We collected data on date production, AGDP and CO2 emissions from different resources covering the period from 1990 to 2019. To analyse the data, we used the Engle-Granger two-step procedure, autoregressive distributed lag (ARDL) bounds methods of analysis, regression analysis and forecasting tests. Results from fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) analyses helped confirm the results of the ARDL model. The results revealed that there are long-run relationships between AGDP and date production and between CO2 emissions and date production. The first result is consequent with theory and leads to economic growth, whereas the second result indicates a negative effect on the environment. To ascertain which production factors were responsible for this negative result, we ran a regression analysis, and the results indicated that the coefficient of electricity consumption (independent variable) was positive and highly significant in explaining the variability of CO2 emissions. The results of the regression analysis also showed that agriculture affected the environment negatively through increasing CO2 emissions during the study period. Forecasting analysis results showed a decrease in CO2 emissions for the period from 2020 to 2026. The study results lead us to recommend that, to increase economic growth, date production should be increased along with the synchronised use of renewable sources of electricity. The governmental effort to sustain the environment also should be increased and continued through increasing the share of renewable electricity in total electricity consumption.

Globalisation is also having a profound impact on international agricultural trade. This study examines the impact of regional trade agreements (RTAs) and globalization on international maize trade using a gravity model for the period 1996–2020. The results show that, despite globalization, distance has a larger negative impact on bilateral maize trade than on the manufacturing sector. It appears that distance remains an important factor in explaining trade flows in commodity markets, including maize. Our findings on the role of RTAs are in line with the results of previous studies: RTAs are generally preceded by a strengthening of bilateral trade relations. There is mutually positive feedback between the level of bilateral trade and RTA membership. However, the establishment of a common RTA membership and its trade-stimulating effects are not immediately visible.

The paper analyses the effect of electronic-trading (e-trading) on the wholesale prices of select commodities in agricultural marketplaces to aid agrarian income levels. Post a literature review, the researcher performed a field survey to get the opinions of 371 farmers and traders. The researcher also conducted the descriptive statistical analysis, the difference in differences analysis, and the t-test analysis to show the wholesale price improvement after the e-trading platform implementation. The field survey findings and the statistical analysis suggest an increase in average wholesale prices of select agri-commodities in select markets of India due to the National Agriculture Market (eNAM) e-trading platform effect. The suggestions to practitioners and social policymakers highlight an improvement in the functioning of e-trading in terms of better prices for farmers, lowering transaction costs, increased transaction speed, reduced administrative hurdles, improved infrastructure and eventually higher income for a farmer. The knowledge base developed in this paper will help researchers reduce the knowledge gap in agricultural pricing.

Since the LEADER (Liaisons Entre Activités de Developpement de l'Economie Rural) method was launched in 1991, through its Rural Development Programmes, it has tried to support rural areas by promoting the creation of opportunities, strengthening rural territorial resilience and holding back depopulation processes. It has also introduced social considerations such as gender and age and has fostered the knowledge economy. One aspect of particular interest is employment: rural areas that offer employment opportunities can trigger a set of processes and dynamics that are positive for rural resilience in that they strengthen competitive, socially dynamic and economically viable spaces. The purpose of this article is to define the profile of a LEADER project that can generate and/or consolidate employment in the Spanish region of Castilla-La Mancha during the current 2014–2022 programming period. This is done by means of a study using ordered probit of the 4 465 projects by the Local Action Groups (LAGs). The study points to the preponderance of agro-industrial activity and the large size of the municipalities where employment is generated. It also finds that a very large proportion of the jobs created are for young people and that many women have found jobs in projects funded by the LAGs.

Technology has made it possible to achieve the very efficient use of water resources in agriculture. However, there are a set of practices that could increase both the availability and quality of the water resources, but which are not yet widely used. In view of the scarcity situation mainly produced by the consequences of climate change, the objective of this work is to analyse the adoption of sustainable irrigation management practices in agriculture. To this end, the aim is to identify and evaluate the variables involved in adopting sustainable practices in agriculture through the use of different qualitative research tools in successive phases (literature review, in-depth interviews, Delphi method and workshop). The results indicate that the sustainable practices to be adopted to improve water management in the study area are rainwater harvesting (RWH) and pond covering (PC). The main barriers are the costs, some farm characteristics and lack of research, while the facilitators include easy access to technology and the existence of farmer-to-farmer networks. Furthermore, the most influential stakeholders for these practices are the farmers, policymakers and researchers. Proposals for the adoption of sustainable water use practices have also been made consensually with all the involved agents.

In this paper, we aim to identify the intensity and nature of intra-industry specialisation in the global trade in citrus fruits. We used data from the United Nations Comtrade database. We performed both static and dynamic assessments of the intensity of intra-industry trade (IIT) by using the traditional Grubel-Lloyd index and the marginal IIT (MIIT) index, respectively. We also separated IIT into horizontal and vertical trade, and we verified the relationship between changes in the intra-industry pattern of trade and the level of comparative advantage gained by the largest producers and exporters of citrus fruits in the world. We used the revealed symmetric comparative advantage (RSCA) index to evaluate the level of international competitiveness. Conducting these analyses allowed us to fill the existing research gap by identifying the nature of IIT in products with specific quality characteristics but at a lower processing stage. The study's results indicated that the stronger the IIT or the more intensive shifts toward deepening the intra-industry specialisation, the lesser the comparative advantage of a country in the global export of citrus fruits. Nevertheless, the increased intensity of intra-industry specialisation does not always lead to a deterioration in the value of the trade balance.

In recent literature, the issue of sustainability and its measure has been addressed with different approaches that depend on the multidimensional nature of the concept and the specific sector and context to which it applies. The present work focuses on the economic sustainability component and suggests an operative measure at the farm level. The measure of economic sustainability has been applied to Italian family farms using Farm Accountancy Data Network (FADN). Based on this data, an efficiency indicator (EI) and two income indicators [a factor profitability indicator (FPI) and a comparable income indicator (CII)] expressing the ability to remunerate the entrepreneur's production factors at their opportunity cost and the farm's income capacity have been used in a principal component analysis (PCA) to build an economic sustainability index (SI). The index was used to describe Italian farms' economic sustainability levels but was also the cue to discuss problems related to identifying economic sustainability thresholds and the trade-off between efficiency and income components.

The price of fertiliser, which is one of the most important inputs of agricultural production, has increased significantly in recent years. In this study, we empirically analysed the effect of volatility in fertiliser prices on selected agricultural products by using the Diebold-Yilmaz connectedness approach, which is based on time-varying parameter (TVP) vector auto-regression (VAR). The findings showed that the spread of volatility and the interconnectedness between these variables increased in times of crisis and that the risk pass-through was due to fertiliser prices. However, empirical results showed that the price volatility of phosphate rock and urea was highly correlated to the volatility of other products. Furthermore, we found that sugar, soybean and cotton were the agricultural products most vulnerable to the effects of external shocks.

The human population is highly dependent on electricity, and to maintain the current progress of its use and for future requirements, it is necessary to look for ways to ensure sufficient energy. The aim of the article is to compare nuclear energy as a representative of non-renewable energy sources with photovoltaic energy as a representative of renewable energy sources (RES). The comparison is made in terms of the effect on agricultural land occupation, given that soil as a basic production factor is completely unique and that nuclear energy sources are often used as a backup for RES. We used a quantitative research method based on deduction using available real data to compare agricultural land occupation by these two energy sources. The results indicate that the effect of photovoltaic power plants on agricultural land occupation is 100 times greater than that of nuclear power plants. In terms of the effect on agricultural land occupation, the combination of solar and nuclear power plants seems to be appropriate. This combination partially eliminates the negative agricultural land occupation consequence of using solar power plants.
