Most employee satisfaction studies do not consider the current digital transformation of the social world. The aim of this research is to provide insight into employee satisfaction in agribusiness by means of coaching, motivation, emotional salary and social media with a value chain methodology. The model is tested empirically by analysing a survey data set of 381 observations in Spanish agribusiness firms of the agri-food value chain. The results show flexible remunerations of emotional salary are determinants of employee satisfaction. Additionally, motivation is relevant in the production within commercialisation link and coaching in the production within transformation link. Whole-of-chain employees showed the greatest satisfaction with the use of social media in personnel management. Findings also confirmed that employees will stay when a job is satisfying. This study contributes to the literature by investigating the effect of current social and digital business skills on employee satisfaction in the agri-food value chain.

Agricultural parcels are often the subject of land valuation studies. This approach implicitly assumes that the real estate value of the land belonging to a farm is the sum of the values of the individual parcels that make up the farm. Nonetheless, the value of a whole can be very different from the sum of its parts. This study proposes a methodology for calculating the real estate value of the land belonging to a farm, by including parameters relating to the fragmentation of the land. Fragmentation increases production costs and reduces farmers’ incomes and by extension the real estate value of the farm. In our study area, the province of Jaen in Spain, figures for its most emblematic crop, the olive, show that fragmentation of the land reduces its value by between 51% for a 10 ha farm and 12% for a 30 ha farm as compared to the values set out in the bibliography. The reorganization of the ownership system or the promotion of systems for the common management of land could increase the profitability and therefore the value of land according to the ‘income capitalization’ approach.

Climate change is responsible for the negative effects in human life causing a decrease in agricultural products, biodiversity, soil fertility, and forest areas. In contrast, climate change increases plant diseases and pests, the cost of agricultural production and risk in food security. This study aims to determine whether climate change is a phenomenon via the analysis of the perceptions of the farmers in the Mersin province conducted over 251 questionnaires. Farmers primarily perceive climate change over production costs and the reduction in yield. Moreover, they are highly aware of its relation to natural events such as floods, drought, and storms. Nevertheless, inappropriate agricultural practices also lead to the negative consequences caused by climate change. In this respect, this study revealed that farmers with high cooperative partnerships and experience perceived climate change significantly.

The objective of this study was to measure the efficiency level of Water Users Associations (WUAs) in the coastal oases of Gabès (South-Est of Tunisia) and assessing its main determinants. First, an input-oriented data envelopment analysis (DEA) was used to measure the relative efficiency scores of WUAs and to evaluate the management and maintenance costs sub-vectors efficiencies separately through a mathematical modification in the initial DEA specification. In a second stage, critical determinants of sub-vector efficiency are determined by applying a Tobit model. A key finding of the study is that WUAs are clearly inefficient. Results show that on average, 38% of the used inputs could be saved if the WUAs operated on the frontier. The inefficiency found can be mainly attributed to the number of water pumping stations managed, the ratio of water losses and WUAs' age. The results also show a discrepancy between the technical efficiency values calculated under the CRS and VRS assumptions, resulting in a 20% scale inefficiency. The study also revealed that the sub-vector inefficiency of WUAs is more linked with engineering inefficiencies than to their management inefficiencies.

Nile water availability is one of the major constraints for agricultural development in Egypt. This study conducts a mixed multiplier analysis, under water and land constraints, to identify the seasonal agricultural activities with high output and income multipliers. It uses a 2008/09 SAM for Egypt with detailed representation for Nile-related production factors employed by agricultural activities across irrigation seasons. The results demonstrate the significance of addressing Nile water constraints not only for agriculture, but also for the overall economy. Policies that enhance water productivity, particularly in winter season, generate outstanding increases in output, income, and employment through sizable multiplier effects.

Demand for animal products is expected to increase due to human population growth, resulting in a need for increased production. At the same time, climate change poses a major threat to the viability and sustainability of livestock production systems. This study aimed to evaluate and compare the sus-tainability of dairy cattle farms belonging to three farming systems (rainfed, irrigated, and mixed) at the northeast zone of Tunisia using the IDEA method (version 3). Collected data of 102 farms were subjected to an analysis of variance using the GLM procedure of SAS software (version 9.4). Results showed that the socio-territorial scale was the limiting factor for all systems and that the irrigated sys-tem had the lowest scores of agro-ecological and socio-territorial scales, compared to the other ones, but it recorded the highest score for the economic scale. The best agro-ecological and socio-territorial scores characterized the mixed system. However, it had the lowest score on the economic scale. Finally, the rain-fed system was exhibited medium performances of the three scales. It was concluded a differ-ence between the three farm systems, but there was no disassociation between the three sustainability dimensions; thus, improvements should proceed across all scales simultaneously.

Community supported agriculture (CSA), an innovative food distribution model that encourages environ-mentally sound agricultural production, has been embraced in Turkey since the early 2000s. Although the model has been widely studied within the framework of ethical consumption, environmentalism and social justice, its perspectives as a domain of economic exchange in Turkey has yet to be explored. The present study attempts to investigate the viability of CSAs in Turkey as domains of economic exchange by looking at the interaction between their performance and their main resource, namely their social capital. Following an exploratory approach, we, first, examined the characteristics of the operational, organizational and sup-port models to determine the performance factors indispensable for CSAs in Turkey to survive as domains of economic exchange. We then expanded this understanding by looking into the relationship between these performance factors and social capital indicators of three CSAs in Turkey. The findings reveal that each CSA adopts different support, operational and organizational models that result in different levels of risk shar-ing. In all three CSAs, the character of the social capital that interacts with the performance indicators is bonding rather than bridging. Therefore, investing in bridging social capital can be a potentially beneficial strategy for CSAs in order to become more sustainable as domains of economic exchange.

This research aims to examine the existence or not of a relationship between governance and pulse’s food security in Morocco in terms of food availability, accessibility, utilization, and stability and to determine the governance indicators affecting food security. The methodological approach pursued combines ordi-nal logistic regression and qualitative analysis based on perceptions of thirty-four actors representing the value chain links of pulses. The results obtained show a relationship between governance and pulse’s food security in terms of accessibility and stability rather than in terms of food availability and utilization. The most significant governance indicator affecting accessibility is the piloting and control of the sector. While none of the following indicators, affecting stability, are significant: the degree of information shar-ing on the distribution system, the degree of transparency, and the degree of trust between actors. How-ever, the emergence of constraints relating to coordination, commitment, trust, and information sharing between actors are not favorable to a decisive role in food security governance.

In the region of M'Sila, a steppe zone and characteristic of a dominant agro-pastoral framework, the local olive sector has certainly grown in terms of area expansion, but the information available indicates that its future in terms of performance is dependent on a series of internal and external factors. The aim of this article is to highlight the main explanatory variables by analyzing the strengths and weaknesses of the sector, the opportunities and threats linked to its environment. Two methods are used: the first, SWOT, constitutes a structured diagnostic framework and a universal decision-support tool. The second, the causality analysis, according to the Parmenides EIDOS tool, makes it possible to obtain a hierarchy of relations in the sector based on the opinions of the intervening actors. The data used come from the bibliographic summary of a series of studies and the results of a survey carried out in 2017 in the field. The results obtained show that the internal factors are linked to the characteristics of the farms, to the production systems, and to the surrounding conditions of the value chain. External factors are linked to the dynamics of national and global markets.
