The objective of this paper is to identify prospects for stakeholder cooperation for effective implementation of enhanced rangeland restoration techniques under different land tenure status in Tataouine Governorate of southern Tunisia, through the rest technique locally called “Gdel.” This technique consists of leaving a given rangeland at rest to reconstitute the plant cover. A stakeholder analysis was conducted using the MACTOR methodological framework to analyze stakeholders’ strategies and their balance of power in terms of rangeland management decisions, specifically regarding the implementation of resting, which involves a high level of collective action. Data collection was based on two focus group discussions with the nine main stakeholders involved directly and indirectly in Tunisian rangeland management. Stakeholders’ perceptions about resting are compared across private and collective land tenure systems. Findings show a wide diversity in stakeholder relationships, in terms of influences, dependencies, and balance of power, with differences between collective and private tenure systems. In private rangelands, equal levels of stakeholder influence and power lead to a much more stable and flexible rangeland restoration process, with more alliances and consensual objectives among almost all stakeholders. The situation in collective rangelands is very different because the majority of stakeholders have a weak influence in terms of management decisions, with fewer alliances and more conflictual objectives among them. Pathways for stakeholder cooperation and long-term empowerment are suggested for effective implementation of rangeland restoration techniques involving collective action.

The objective of this research study was to assess the sources of information on two improved agricultural and livestock technologies (barley variety and feed blocks) as well as the efficacy of numerous agricultural technology diffusion means introduced in the livestock–barley system in semi-arid Tunisia. The research used primary data collected from 671 smallholder farmers. A descriptive statistical analysis was conducted, and Kendall’s W-test and the chi-squared distribution test were deployed to categorize and evaluate the efficacy of the different methods of technology diffusion used by the Tunisian extension system. To address farmers’ perceived opinions and classify the changes from the use of the improved technologies, a qualitative approach based on the Stapel scale was used. Farmer training, demonstration, and farmer-to-farmer interactions were perceived as the most effective agricultural extension methods. The access to technology, know-how, adoption cost of that technology, and labor intensity for adoption influenced its adoption level. Farmers’ opinions about the changes resulting from the adoption of both technologies revealed that yield and resistance to drought were the most important impacts of the two technologies. The study recommends empowering the national extension system through both conventional and non-conventional technologies (ICT, video, mobile phones, etc.), given the cost-effectiveness and their impact on the farmers’ adoption decisions.

In order to develop a sustainable date palm production system in the Gulf Cooperation Council (GCC) countries of the Arabian Peninsula, an analysis of the date value chain in these countries was undertaken. Through the mapping of the chain, the overall objective was to identify the processes where values are created and how they are distributed among stakeholders along the entire date palm value chain. The method used in this analysis was based on an assessment of the data gathered from the multi-stakeholder surveys implemented in the three case studies of the GCC countries: Kingdom of Saudi Arabia (KSA), Oman, and Kuwait. The empirical findings reveal several problems and constraints that might affect the future of the GCC date palm sector. Therefore, development of a competitive supply date palm chain (both market and agribusiness development) could provide a greater contribution to the GCC economy if producers paid more attention to marketing of this very important food commodity. Hence, date palm production is no longer a way of life but nowadays is considered as an investment option and source of revenues for many stakeholders if the GCC region.

Mechanized raised-bed technology (MRBT) is recognized as an important measure to achieve higher crop productivity and water-use efficiency in intensive irrigated systems. Development efforts on spreading this technology require adequate understanding of the qualities and drivers of farmers’ adoption of MRBT. Research in agricultural innovation adoption has identified the importance of the socio-ecological context (SEC) that influences the livelihood of farmers adopting new technologies. This study introduces an agricultural livelihood systems (ALS) typology-based approach for guiding concrete analytical steps and statistical methods in evaluating the effects of system SEC diversity in two Egyptian governorates. We objectively classify a population of sampled farming households into a limited number of ALS types and use inferential statistics for the whole sampled population and individual ALS types to discover adoption drivers. Values added by the ALS approach confirm the widespread role of common determinants of MRBT adoption across ALS types, household groups subject to the effects MRBT, and show new causal effects. The presented advanced approach and empirical findings will be useful for enhancing targeting and out-scaling of MRBT practices toward achieving sustainable agricultural water uses at scale.

Due to the decrease of household incomes, the increase of food prices, and the negative effects of climate change on agricultural production, Tunisia faces a food insecurity challenge, especially in rural and arid areas. The purpose of our research is to understand and explore household resilience to food insecurity in two villages, Selta and Zoghmar, in central Tunisia. A cross-sectional survey of 250 sample households was conducted in the villages. Factor analysis and regression models were employed to analyze the data using SPSS version 21. The results indicate that only around 36% of the households were resilient at different levels. In Selta, 62.8% and in Zoghmar 66.7% of the households were vulnerable. As indicated by the factor loadings and beta coefficients, income and food access, adaptive capacity, and the social safety net were important dimensions of household resilience to food insecurity, being positively correlated with the resilience index. However, asset possession, and climate change negatively affect household resilience. Therefore, interventions must target strategies that address the different levels of resilience reflected by the resilience estimators. These estimators were generated by focusing mainly on building farmers’ knowledge of how to face the different difficulties and challenges.

The aim of this research paper is to assess the adoption level of the two technologies (liquid pollination and polycarbonate drying houses) in the Sultanate of Oman with emphasis on identifying influencing factors of the adoption process and exploring resulting policy implications. The methodological framework used is based on the implementation of the ADOPT (Adoption and Diffusion Outcome Prediction Tool) tool in two localities of the Sultanate of Oman through focus groups discussion (FGD’s). Empirical findings obtained from the assessment of the Liquid Pollination (LP) technology indicate that peak adoption rate for liquid pollination technology in “North Al Batinah” is high and predicted to be around 95% (of the total population) after a period of 14.5 years. The predicted adoption level after 5 and 10 years from introducing the technology in the region is estimated to be 46.9% and 91.5%, respectively. The assessment of the rate of adoption of the Polycarbonate Drying Houses (PDH) technology and the identification of factors affecting the peak and adoption levels, and constraints that limit the adoption process and widespread of such technology among the date palm growers of Oman indicates that peak adoption rate for PDH technology in the target study region is predicted to be 95% after a period of 21 years. The predicted adoption level after 5 and 10 years is expected to be 23.5% and 72.9%, respectively. The presented results suggest that sustainable increase in date palm productivity can be achieved if farmers are encouraged to adopt the LP and PDH technologies. However, the adoption of such technology needs to be accompanied by a supporting extension system and an enabling policy environment to ensure the scaling-up and widespread use of these promising and profitable technologies.

In the frame of the ICARDA project “Development of sustainable date palm production systems in the GCC countries of the Arabian Peninsula”, researchers succeeded to introduce one promising technology (subsurface drip irrigation - SDI) in the date palm farming system in the Gulf region, defined as the poorest in the word in terms of water resources. In the light of these challenges, the main objective of this study is to evaluate the effect of the irrigation water volumes on the date palm productivity and water use efficiency under several conventional and improved irrigations systems.Three intervention levels on SDI have been used: at the rate of 60% 40% and 20% of water requirement. Results of this experimental study showed that SDI under the three intervention/options uses water more efficient in comparison to BI. Indeed, a considerable quantity of water for about 3545.554, 5726.45, and 7565.473 m3/ha could be saved by using SDI at the rate of 20%, 40 and 60% of water requirements, respectively. Thus, the WUE indicator is for about 2.0, 2.7, and 4.7 kg/m3, respectively. These figures are much higher when are compared to BI system where WUE is around 1.3 kgm-3.The economic evaluation suggests that under BI system, the total return, total variable costs, water costs and net profit were 20211.36, 5857.81, 1224.29, and 13129.25 $ ha-1, respectively. From another hand, by using SDI at the rate of 60% of water requirements, we note a slight difference in net profit when using this irrigation system, which is about US$12825.02/ha. Economic findings suggest that using SDI method versus BI method have additional cost but is economical at the long term as the SDI found to sustain the date palm farming system in this region where arid conditions acts as natural constraints for expansive agriculture.

We investigate the factors that affect total factor productivity growth in MENA countries. To this end, we start first by examining levels and trends in agricultural outputs and productivity growth using Torqnovist Indexes and then computing Malmquist Indexes for three MENA countries representing three different agro-ecological areas; irrigated (Egypt), rainfed (Tunisia) and rangeland (Jordan) over the period 1961-2012. We make use of data drawn from the Food and Agriculture Organization (FAO) dataset. The advantage of this decomposition is that allows decomposing TFP into its two components, namely technical efficiency (TEF) and technological change (TECH). The analysis was complemented by econometric regression of the obtained TECH, considered as the most important long-run driver of TFP growth, scores on a set of potential explicative variables. Turning to the determinants of the components of TECH, the paper findings showed that TFP can be increased due to the increasing in human capital, share of the main crop harvested in each country, and resource reallocation-agricultural employment share. The main implication policy of this research is that growth and determinants of TFP are essential for assessing the country past and potential economic performance, and the gains in TFP drive gains in income and growth.

In the GCC countries, date-palm sector is strategically important for the economic, social and environmental development. Therefore, markets globalization has had a huge impact on the comparative advantages of date exports from the GCC countries, highlighting a new range of necessary determinants for competitiveness of these countries on the international date palm date market. The current study is conducted in the framework of the “Development of sustainable date palm production systems in the GCC countries of the Arabian Peninsula” project funded by the Gulf Cooperation Council (GCC) and led by the International Center for Agricultural Research in the Dry Areas (ICARDA), and aims to provide updated estimates of competitiveness indicators of the GCC countries on the international market of date palm.The study starts by a summary description of updated figures concerning date’s production, yields, and consumption trends of the different GCC countries. This first part of the research paper also includes a presentation of the date trade matrix (destinations of exports and imports) of the considered countries. In a second part of this section, a set of competitiveness indicators were calculated to better reflect on the date trade balances performances of each of the GCC countries. The measures of competitiveness indicators conducted in this paper include: i) the Market Share (MS); ii) the Revealed Comparative Advantage (RCA); and iii) the Trade Balance Index (TBI). The Market share indicator was used to identify size advantages and the degree of specialization of a given country on the international market of a given commodity. The RCA has been defined as a measure of performance of international trade competitiveness of a given country for a given commodity. The TBI is used to analyze whether a country has specialization in export (as net-exporter) or in import (as net-importer) for a specific group of products. Data from both FAOSTAT and UN COMTRADE sources was used for the calculation of these indicators. Empirical findings show that GCC and North African countries are holding more than 70% of the international market of dates. The sum of market shares of the 6 GCC countries was about 30% of the international date market during 2015. This is showing that these countries together have strong potential for dominating the international date market. In terms of growth, it was clear that all GCC countries, including the least present on the international market are progressing quite positively with increasing shares from one year to another. In terms of RCA, the highest RCA value was recorded for Saudi Arabia (KSA). It was for about 43.5 in 2013, indicating that the country date export share for 2013 is 43.5% higher than its share in total world export of agricultural goods. Finally, TBI results show the existence of structural differences between KSA and UAE in terms of dates export and import patterns. These two countries are both the main players in date export in the GCC area. However, even though UAE is a net exporter of date palm, which its TBI is much lower than the TBI of KSA, showing that UAE is also importing a higher proportion of its exported dates compared to KSA. The date trade patterns among the GCC countries shows that there is a wide scope of coordination between the different trade strategies of these countries, through specialization and division of tasks. This can generate important opportunities for gaining more weight on the world market of dates.

The main objective of this study is to assess the rate of adoption of innovations introduced by the Arabian Peninsula Regional Program (APRP) of ICARDA and identify main constraints that limit the adoption process of these new technologies in the GCC countries and Yemen through using ADOPT (Adoption and Diffusion Outcome Prediction Tool). ADOPT predicts the proportion of a target population that might adopt an innovation over time. A focus group discussion (FGD) methodology was used to apply the ADOPT with a panel of farmers in each country and for each introduced technology. In the FGD we streamlined 22 discussion questions around four categories of influences on adoption: characteristics of the innovation, characteristics of the target population, the relative advantage of using the innovation, and learning of the relative benefit of the change.The results showed that predicted peak of adoption and time for reaching that peak vary between technologies, countries, and within the same country. The technology specific variables (e.g. yield potential and acceptability) are significant for explaining adoption behavior, implying that it is important to take farmers’ preferences to varietal characteristics into consideration in the design of a research and development program. Given the significant role played by extension and access related variables, increased emphasis on information dissemination, field demonstration, and farmers’ participatory research and training programs to popularize these technologies and enhance their adoption rate are required. This also suggests that policy intervention should be made on improving the knowledge status of farming households, and developing programs on the technological package which offer farmers a variety of choices among the appropriate pools of technology options. Such programs ultimately help farmers to develop more profit-oriented behavior (both economically and environmentally) which are necessary to enhance adoption rate, production, and food security in the long run for the GCC countries and Yemen.

The aim of this paper is to examine the impact of research, development extension (RD&E) and climate change (measured in terms of change in rainfall) on the productivity growth of agriculture in Tunisia during the period 1970–2011, using output-based Törnqvist index combined with econometric regression. Results show that RD&E and climate change are significantly affecting the long-run productivity growth of the Tunisian agriculture. Climate change lessens the productivity of agriculture in the long run whilst RD&E boosts its productivity. Empirical findings suggest that an increase in agricultural RD&E investment is critical to improving long-run productivity growth in the face of adverse climate change.

Studies on migration in the Middle East and North Africa (MENA) region have so far focused on migration to urban areas (local cities and European countries). Little research has explored internal migration into rural areas. Yet in Morocco rural-rural migration is an important strategy for many who are escaping climate variability and unemployment in their hometowns to take advantage of labor opportunities in thriving agricultural enterprises. Gender remains largely missing from migration research in Morocco especially for migrant women. Gender differences are important to account for as men and women have diverse motives, strategies and experiences with migration, and thus require different interventions. In light of gender differences and climate-induced migration and investments in irrigation, this research follows up on the ground to understand the experiences of men and women laborer as the migration continues in three rural areas in the Saiss region (Morocco). These are chosen based on differences in socio-economic, gender norms, and biophysical dynamics to capture as diverse experiences as possible with labor work and migration as possible. These areas also represent both sending and receiving communities. Data was collected through a survey administered to 400 laborers (179 women and 221 men) employed in the intensified agricultural sector of Saiss in Morocco. Using gender analysis, logistic regression models framework and political ecology approach, our findings emphasize that men should be sensitized in their attainment of tertiary education on gender equality and the importance soliciting women’s participation in decision-making, particularly with regards to assets (house). For the economic advancement of women, there should be a sustained focus on their ownership and control over unalienable assets (such as housing). The same recommendation applies to the youth. Finally, we found that migrants were less likely to control houses that they owned probably du

Energy use efficiency is a key requirement for sustainability in agricultural production, but often overlooked. The aim of this study was to quantify the amount and efficiency of energy consumed in the production of onions and potatoes in El Hajeb province of Morocco. These estimates are of significant importance in informing contemporary policy discourse related to energy subsidy reform in Morocco, and more specifically within an ongoing national strategy for ‘modernizing’ the agricultural sector under the ‘Green Morocco Plan’. Data were collected through the administration of a direct questionnaire with 60 farmers and analyzed using PLANETE. Our results indicate that total energy consumption in onion production is 107483 MJ ha-1 with butane (79.5%) as the main source of direct energy. Chemical fertilizers (61.53%) and water for irrigation (30%) were main sources of indirect energy. Energy indices related to energy efficiency ratios, energy profitability and energy productivity were estimated at 0.78, -0.22 and 0.54 kg MJ-1, respectively. Total energy consumption in potato production was estimated at 74,270 MJ ha-1, with direct energy consumption of 28,521 MJ ha-1 stemming from butane (70%) and diesel (19.14%) as primary sources. Indirect energy consumption was estimated at 45749 MJ ha-1 and generated principally through the use of fertilizers (60%). Energy indices (efficiency, profitability and productivity) were estimated at 1.54, 0.54, and 0.45 kg MJ-1, respectively. GHG emissions were found to be 3.47 t CO2eq ha-1 in the production of onions and 3.63 t CO2eq ha-1 for potatoes. We find that within the study area, increases in the size of production plots are not necessarily consistent with increases in energy use efficiency.

This article develops new estimates of historical agricultural productivity growth in Jordan. It investigates how public policies such as agricultural research, investment in irrigation capital, and water pricing have contributed to agricultural productivity growth. The Food and Agriculture Organization (FAO) annual time series from 1961 to 2011 of all crops and livestock productions are the primary source for agricultural outputs and inputs used to construct the Törnqvist Index for the case of Jordan. The log-linear form of regression equation was used to examine the relationship between Total Factor Productivity (TFP) growth and different factors affecting TFP growth. The results showed that human capital has positive and direct significant impact on TFP implying that people with longer life expectancy has a significant impact on TFP growth. This article concludes that despite some recent improvement, agricultural productivity growth in Jordan continues to lag behind just about every other region of the world.

This research aims to assess the Total Factor Productivity (TFP) of the whole agricultural sector in Egypt for the period 1961-2012 using Törnqvist index calculations. Particularly, it aims to investigate: (1) the most important factors explaining the TFP growth in the Egyptian agriculture (2) estimating changes in technical efficiency and technical change and determining the magnitude of their contribution to the overall TFP growth, and lastly, (4) based on these findings, providing policy implication and recommendations that allows enhancing and sustaining future growth of agricultural production in Egypt.The currently analysis provided relevant results which might help us understanding the structural trend of the Egyptian agricultural sector, and understanding the most significant variables affecting this trend. Such results will have important policy implications for promoting further growth in the Egyptian agricultural sector. The empirical findings showed that rural development variables were found to significantly and negatively affect agricultural productivity. This demonstrates that agricultural activity is still a marginalized activity which is linked to low levels of income and is a source of employment for low productive labor. Moreover, a negative significant effect of the infrastructure variable on the productivity gains of the agricultural sector in Egypt was found which might indicates a form of low integration of farmers within large neighboring markets. These findings highlighted the decisions makers to take a deeper look at their rural infrastructure strategy, knowing that it may affect the productivity of the agricultural sector as whole.

We apply the Ricardian approach to analyse the economic impact of climate change on agriculture using the 2007 World Bank Tajikistan Living Standards Survey. The study analyses data of 2557 farm households in 166 villages across the 10 agro-ecological country zones. In general, the results indicated that increasing temperature and precipitation will both be damaging to Tajikistan agriculture and consequently to the net revenue (NR) of farmers in the medium and long term. Regressing NR on climate parameters, household and soil variables showed that these variables have a significant impact on the farmers' NR per hectare. We examined the impact of the current climate on farmers' NR per hectare, and how that is affected by future climate scenarios: one +2.9°C warming and one 4.6°C warming scenarios. Although the analysis did not incorporate variables such as the carbon fertilization effect, the role of technology or the change in prices in the future, significant information for policy-making can be extracted. Tajikistan has very diverse regions in terms of geography, population density and socio-economic situation; our results will help policy-makers to anticipate the adaptation effort needed in different locations of the country.

This paper measures the potential economic impact of climate change on durum wheat in Tunisia using the Ricardian approach. A model using panel data was estimated for the period 1990–2010 over the main cultivation regions. Gross margin of the durum wheat under rainfed conditions was used as the dependent variable while the explanatory variables were mainly related to climate such as precipitation and temperature, technological progress, and type of soil. Empirical findings show that precipitations during different stages of the growing season affect positively net-income. In addition, the interactions variables between temperature and precipitation in different growth stages are negative. The assessment impact of technology shows a positive coefficient of trend parameter but not statistically significant. Finally, the soil quality index parameter is positively correlated with the net revenue per hectare. This finding indicates that good quality of soil may improve the net income of farmers by increasing wheat yields. Climate change impact was simulated using scenarios from the HadCM3 global circulation. Empirical results indicate that economic impacts are not uniformly distributed across the different regions of Tunisia. These impacts are likely to be more accentuated in the arid regions. A rise in temperature and a reduction in rainfall would cause reductions in gross margin by 4 % in sub-humid areas and 24 % in arid zones. The results further suggest the necessity for wider diffusion of drought-tolerant varieties among farmers and the identification of new agricultural practices as advisable adaptation strategies in order to alleviate the effects of climate change on farmer’s income.
