Mon projet de stage a été réalisé sur le secteur de Rihana (délégation de Regueb, gouvernorat de Sidi Bouzid), une des zones dintervention de PACTE. Son objectif est de créer un jeu de simulation, avec les acteurs concernés par la problématique[...]Article
A. Attia ; A. Attia ; S. El-Hendawy ; N. Al-Suhaibani ; M.U. Tahir ; M. Mubushar ; M. dos Santos Vianna ; H. Ullah ; E. Mansour ; A. Datta |Crop models may potentially explore alternative ways to improve agroecosystem resilience in arid regions of Middle East and North Africa. Mapping the outputs behavior as a function of the inputs and quantifying the uncertainty contribution of in[...]Article
Water storage requirements in the Mediterranean region vary in time and are strongly affected by the local geography and climate conditions. The objective of this study is to assess the implications of climate change on the water balance of an a[...]Article
R. Padró ; E. Tello ; I. Marco ; J.R. Olarieta ; M.M. Grasa ; C. Font |There is a need for a socioecological transition towards sustainable agri-food systems that recover the organic functioning and the closure of socio-metabolic cycles at the lower feasible scales. This implies an agroecology leap forward aimed at[...]Article
Decision support systems and models for aiding irrigation and nutrient management of vegetable crops
Vegetable growers in Europe are continually under increasing pressure to optimize irrigation and nutrient management. This results from the widespread effects of climate change and of competition from other sectors for water, and increasing soci[...]Article
This introductory article presents the three main challenges faced in economics to issues raised by dietary models. The first part of this paper examines the dietary models that maximise the health profile of a population under various constrain[...]Article
Land reclamation is critically required to overcome the environmental and anthropogenic challenges in arid lands. The Western Nile Delta region, Egypt, is experiencing rapid reclamation processes for agriculture expansion. West Nubaria (781.92 k[...]Article
M.L. Giannitsopoulos ; A.R. Graves ; P.J. Burgess ; J. Crous-Duran ; G. Moreno ; F. Herzog ; J.H.N. Palma ; S. Kay ; S. Garcia de Jalon |There is an increasing demand to study the long-term effects of land use from both local farm and wider societal and environmental perspectives. This study applied an approach to evaluate both the financial profitability of arable, agroforestry,[...]Article
J. Rocha ; C. Carvalho-Santos ; P. Diogo ; P. Beça ; J.J. Keizer ; J.P. Nunes |Future climate for the Mediterranean climatic region is expected to bring an increase in temperatures, decrease in the precipitation quantity and shifts in the seasonal precipitation pattern. Although the impacts of climate change on water resou[...]Article
We examine empirically the predictability of conditions associated with a higher probability of a price spike in agricultural commodity markets. We find that the forward spread is the most significant indicator of probable price jumps in maize, [...]Article
E. Pelzer ; M. Bonifazi ; M. Soulié ; L. Guichard ; M. Quinio ; R. Ballot ; M.-H. Jeuffroy |Legume crops have a number of advantages for dealing with current environmental and food challenges. However, the area under grain and forage legumes has greatly decreased in recent decades in Europe. Attempts to foster the development of legume[...]Article
D. Sarkar ; S.K. Kar ; A. Chattopadhyay ; Shikha, ; A. Rakshit ; V.K. Tripathi ; P.K. Dubey ; P.C. Abhilash |Maximizing food production for feeding a rapidly growing human population while minimizing critical resource use and soil quality degradation is a major challenge for global sustainability. Sustainable agricultural practices based on low-externa[...]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[...]
