This study aims to measure the total productivity of agricultural production factors through the calculation of the Malmquist index for six Mediterranean countries during the period 2003-2018. The results indicate that the growth of agricultural productivity in the Mediterranean region during this period by the calculation of the Malmquist index recorded an increase of 13.2%. Much of this productivity growth is driven by technological change rather than a change in technical efficiency or scale. In fact, the technology change increased by 13%, while the technical efficiency change showed a slight increase of 0.2% due to the scale efficiency change of the same percentage. It should be noted that the total productivity of agricultural production factors and the contribution of technical change and scale efficiency have the same trend at the subregional level, but are different at the country level. These results show that the total productivity of agricultural production factors is highly variable between Mediterranean countries and that the overall efficiency gains obtained are largely due to the phenomenon of technological catch-up rather than to gains in scale or efficiency pure.

This paper investigate how cereal price volatility impacts import bill, tax revenue and foreign exchange reserves in Morocco. It uses GARCH family models to characterize the price and exchange rate volatility functions, ARDL model and Toda and Yamamoto's (1995) causality test to study respectively cointegration and causal relationship. Based on monthly data between January 1999 and December 2019, we find that 1% increase of price volatility and volatility-import leads to respectively increase the import bill by 0.07% and 16.7% on the long run. Meantime, the short-run estimates suggest that the effects of price volatility and the volatility-import level are negative meaning that the lagged value of these variables will have a positive impact on the next month's import bill. Thus, we assume that price volatility should be heavier on the import bill when the annual production is low. Our results also indicate that cereals price volatility can induce serious consequences because it directly causes an increase in the overall import bill and indirectly influences import tax revenues and foreign exchange reserves, especially when it is associated with a poor domestic harvest.
本文研究了谷物价格波动对摩洛哥进口账单、税收和外汇储备的影响。运用GARCH族模型刻画价格和汇率波动函数，运用ARDL模型和Toda and Yamamoto(1995)的因果检验分别研究协整和因果关系。基于1999年1月至2019年12月的月度数据，我们发现从长期来看，价格波动率和波动率-进口增加1%分别导致进口账单增加0.07%和16.7%。同时，短期估计表明，价格波动和波动进口水平的影响是负的，这意味着这些变量的滞后值将对下个月的进口账单产生积极影响。因此，我们假设当年产量较低时，进口账单上的价格波动应该更大。我们的研究结果还表明，谷物价格波动会导致严重后果，因为它直接导致进口总额增加，并间接影响进口税收和外汇储备，特别是在国内收成不佳的情况下。

The objective of this paper is to examine the resilience of households to food insecurity and to identify the determinants of this resilience in two study areas: Kairouan and Zaghouan. The study relied on a cross-sectional database collected from 671 smallholder farmers. Multivariate techniques including factor analysis and linear regression models were used to measure resilience and identify its determinants. The results indicate that the levels of vulnerability and resilience are different depending on the specificity of the region. In Zaghouan, 63% of agricultural households are vulnerable and 28% of households are very resilient. On the other hand, 51% of households surveyed are vulnerable in Kairouan and 42% of households are very resilient. The results reveal that the most important determinants of household resilience to food insecurity are income and access to food, ownership of assets, and access to basic services. The "climate change" negatively affect household resilience and should be further investigated in the long term. Interventions must target strategies that address the different levels of resilience reflected by the resilience estimators.

n emerging countries, information technology (IT) and access to financial services (AFS) are critical determinants determining household income. However, little is known about how IT and AFS work together to increase home wellbeing. This research aims to look into the influence of access to financial services in mediating the impact of IT on household income in Ghana. The study investigates the role of social networks as a moderator in the IT-AFS interaction. A multi-stage sampling strategy was used to collect data from 478 farmers for this study. The study discovered that having access to technology and financial services increases household income. Due to the mediation role of access to financial services, the positive impact of access to IT on household income was also proven. The variable, social network, influenced these mechanisms. This research shows how having access to technology and financial inclusion can help people get out of poverty. This work adds to the body of knowledge. The paper includes policies for ensuring IT and AFS development to improve the welfare of rural households.

Increasing social concern regarding the environmental impact caused by the growth of the world’s population and the need to produce food has led to terms such as sustainability and sustainable food production and consumption to become a current subject of discussion. However, consumers are yet not fully familiar with the concept of sustainability and what it actually entails. This paper uses projective techniques as the ideal methodology to overcome these limitations and analyse the meaning of sustainability for Spanish consumers. Results show that consumers associate sustainability with the environment, although when it is referred to food, other concepts such as local/proximity food and responsible consumption also emerge. Also, while consumers find a clear association between sustainability and organic production, this is not so clear when health is also involved. Finally, respondents’ lifestyles served us as a basis to identify three consumer groups with notable differences in terms of their perception of sustainability. These results point to the need for policies that promote sustainable food production and its awareness by consumers to help mitigate environmental degradation

The present study estimates households' resilience against food insecurity in a selected village of Qalandar Abad district in Iran. The Resilience Index Measurement and Analysis (RIMA) of the Food and Agriculture Organization of the United Nations (FAO) was used for the first time in Iran, to achieve this goal. The samples included 149 farmers randomly selected and the Data were collected through interviews. The factor analysis method was used to estimate the components of resilience, and the MIMIC method was used to estimate the latent variable of resilience. The results showed that the components of asset and adaptive capacity had a significant role in increasing the resilience of rural households in the study area. Variables such as the land area, water availability, and the yield of crops had a significant positive role in improving the asset pillar. The households head and other members' education also had a significant positive effect in improving the adaptive capacity pillar. Therefore, due to time and budget constraints in the execution of macro-policies, adopting and implementing policies that increase the above components will improve the resilience of rural households

Relationship between cooperative-member is very important for cooperatives to continue their activities successfully and effectively. Effective management of cooperative depends on participation of members in the process of cooperative management. The desire to participate in the management varies according to person to person. The main purpose of this study is to determine members’ organizational trust level and examine the willingness to participate of members' into the decision making process according to organizational trust level. Interviews were conducted with142 members in Izmir. Organizational Trust Inventory (OTI) was used. Factor analysis and cluster analysis were used to divide into groups to members’ organizational trust level. It has been determined that the members in the “non-trusting” group are more willing to participate in the management. Age, education and organizational trust, etc. have affected a willingness to participate in cooperative management. Professional management is necessary in order to raise economic and social profit of members. Cooperative leaders should not ignore the opinions of its members and they should also maintain good contact with members.

As the world population is continuously growing, agricultural practices should be done sustainably to achieve food security, nutrition, and economic success. Due to the networking, economies of scale and improved access to information, collective actions and producers' cooperatives seem to be a good instrument for acquiring, sharing and promoting such practices. Therefore, the main aim of this study was to estimate the effect of cooperative membership on the awareness and adoption of environmentally sustainable practices. We purposively selected 210 members and 166 non-members of maize cooperatives in the Southern province of Zambia. To cater for both observed and unobserved bias in the study, we adopted the propensity score matching and endogenous treatment effect models. The study results confirm that cooperative membership positively influences the awareness and adoption of sustainable environmental practices used in the study but encourages the usage of synthetic fertilizers because of the government input subsidy.

The significant development of the commodification of agricultural land in developing countries these last decades, notably through tenancy practices, raises serious questions about the equity of its redistribution. Studies on the equity of land markets show contradictory findings. By analyzing the rental market in the large irrigated perimeter of Guelma, northeast Algeria, this article contributes to this debate by answering the following research question: are tenancy land markets equitable? To answer this question, we essentially surveyed a quarter of the landowners in the main agricultural zone of the perimeter (52/208) and the direct tenants of the surveyed assignors (30) in 2020. We found that in the irrigated perimeter of Guelma, the rental land market has led to (1) the exclusion from the production system of landowners with few resources and unable to provide the necessary means for cash crops that have technically considerably evolved, and (2) the spatial exclusion from good lands of small tenants, relatively inefficient and unable to keep up with large tenants in the level of their rental offer. We refer to this general dynamic as "farmer selection".
