Article
Most crop models were developed and tested in homogeneous field conditions. However, these crop models are increasingly applied beyond the field scale for larger regions. Inadequate representation of the spatial variability at a larger scale int[...]Article

Brilli |As the basis of livestock feeding and related performances, pastures evolution and dynamics need to be carefully monitored and assessed, particularly in the Alps where the effects of land abandonment are further amplified by climate change. As s[...]Article
Cultivation and sustainability of Date palm in Palestine is the main focus of this paper. Lifecycle and food supply chain are represented using integrated definition block diagram showing the inputs and outputs of date palm tree cultivation. Dou[...]Article
Wheat yield potentials under rainfed Mediterranean conditions have been long limited by late-in-season occurrence of enhanced water deficits and high temperatures, coinciding with sensitive reproductive stages. Present study aims to quantify and[...]Article
Dealing jointly with both systemic and social complexity is a challenge that we face with sustainability issues. However, joining these two aspects of complexity is more a post-normal science call than an effective practice. Roughly speaking, [...]Article
A. Elbeltagi ; L. Zhang ; J. Deng ; A. Juma ; K. Wang |Accurate estimation of crop evapotranspiration (ETc) is essential for water resources management, planning, and scheduling. This study focuses on estimating, predicting and modeling crop coefficients kc of maize which is an important parameter f[...]Article
In this paper we argue that there is nothing intrinsically wrong with case studies or environmental modelling. But what is missing is the articulation of necessary complimentary measures (reflected in theory, method, models and techniques for da[...]Article

A. Elbeltagi ; J. Deng ; K. Wang ; Y. Hong |Modeling crop water use as a useful decision tool for agricultural policy decision-makers to improve water-use efficiency has been increasing. This study aimed to estimate, forecast, and model the green and blue water footprints (WFg and WFb, re[...]Article
F. Maggi ; D. La Cecilia ; F.H.M. Tang ; A. McBratney |Agricultural pesticides can become persistent environmental pollutants. Among many, glyphosate (GLP) is under particular scrutiny because of its extensive use and its alleged threats to the ecosystem and human health. Here, we introduce the firs[...]Article
Over the last 30 years, the European Union has significantly reformed its Common Agricultural Policy by introducing direct payments to farmers and reducing price support levels. While the European agricultural prices become more volatile, all ec[...]Article
Crop water production functions (quantifying crop yield as a function of irrigation rate) can help in the design of management systems that reduce the water footprint. We examined the role of parameter uncertainties in characterizing production [...]Article
Desertification is a serious and perilous threat to natural ecosystems. Understanding the spatio-temporal characteristics of this process through the evaluation and monitoring of important indicators appears to be a challenging task. This resear[...]Article
En se focalisant sur le cas de la France, cet article propose une réflexion centrée sur deux instruments de la Politique agricole commune (PAC) qui entendent avoir un impact sur la répartition des aides directes entre exploitations agricoles. Le[...]Article
Article
Two thirds of human water use is linked to agricultural practices including crop irrigation. Furthermore, excess irrigation leads to drainage problems. For this reason, reduced irrigation strategies need to be implemented to protect water resour[...]Article
T. Puech ; A. Durpoix ; F. Barataud ; C. Mignolet |Lors de ces cinquante dernières années, les exploitations agricoles ont connu de profondes mutations : spécialisation, réduction de la main duvre agricole, mécanisation croissante. Ces transformations ont entraîné leur agrandissement et une mo[...]Article
Predicting crop yield response to management and environmental variables is a crucial step towards nutrient management optimization. With the increase in the amount of data generated by agricultural machinery, more sophisticated models are neces[...]Article
In intensive agricultural systems, irrigation and nitrogen (N) fertilizer are the most important factors that influence crop production and N losses. This work aimed to evaluate the N best management practices using the calibrated and validated [...]Article
In Iran, due to arid and semi-arid climate, groundwater resources play an essential role in food production, as well as domestic and industrial water supply. In recent years, increasing population, scarcity of surface water resources, and effect[...]Article
There is a growing consensus that sustainable development requires a behavioral change, forced by firm decision-making. However, existing decision-supporting tools are unlikely to provide relevant information, hampered by the complexity of combi[...]Article
A. Nasrallah ; H. Belhouchette ; N. Baghdadi ; M. Mhawej ; T. Darwish ; S. Darwich ; G. Faour |The promotion of optimum rotations and agricultural management of winter wheat-based cropping systems is very critical, as wheat is considered an essential component in the Mediterranean diet. Considering the delicate economic situation of farme[...]Article
This paper proposes a new composite index to measure the multidimensional concept of food security. Although other indicators with the same objective exist, they come with several methodological shortfalls. The Proteus index makes a twofold cont[...]Article
This study aimed to assess the sustainability in water use at the basin scale through the water footprint (WF). The methodology proposed by the Water Footprint Network was integrated with a hydrological and water quality model and in-stream moni[...]Thèse, Mémoire, Master
