Our study aims to simulate scenarios depending on the type of soil (low and high water retention capacity WHC), the type of rotation (2/3 years), and different management amounts (fertilization and irrigation) in the crop growth model CropSyst[...]Article
Face à un changement climatique sévère projeté, les agriculteurs dans les pays de lAfrique du Nord expérimentent habituellement des stratégies dadaptation basées sur la précocité du semis, lutilisation de variétés précoces et la fertilisation[...]Article

Eza |Dans le cadre de lapplication de la loi sur leau et les milieux aquatiques de 2006, les Organismes Uniques de Gestion Collective (OUGC) sont chargés d'élaborer, pour chaque périmètre élémentaire, un plan de répartition entre préleveurs irrigan[...]Article
S. Neuenfeldt ; A. Gocht ; T. Heckelei ; P. Ciaian |In this paper, we analyse the drivers of farm structural change in the EU-27, applying a novel analytical framework in the field of agricultural economics known as the multiplicative competitive interaction (MCI) model. MCI offers a more parsimo[...]Article
H. Bahri ; M. Annabi ; H. Cheikh Mhamed ; A. Frija |Several circulation models are forecasting climate changes in the Mediterranean region. Accordingly, it is expected that water scarcity in the region will be higher with drastic shifts of hydrological and erosive watershed responses. In Tunisia,[...]Article

Bregaglio |The main cultivation area of the Italian processing tomato is the Southern Capitanata plain. Here, the hardest agronomic challenge is the optimization of the irrigation water use, which is often inefficiently performed by farmers, who tend to ov[...]Article
X. He ; L. Estes ; M. Konar ; D. Tian ; D. Anghileri ; K. Baylis ; T.P. Evans ; J. Sheffield |Understanding the cross-scale linkages between drought and food security is vital to developing tools to reduce drought impacts and support decision making. This study reviews how drought hazards transfer to food insecurity through changes in ph[...]Article
Dans le cadre du projet AdaMont, un concept de système de management de ladaptation (SMA) sinspirant des pratiques du système de management de la qualité (SMQ) a été proposé. Ce concept permet de donner un cadre rigoureux pour mettre la démarc[...]Article
Many approaches (e.g., formal modelling, Futures Studies) taken to understanding global food futures tend to treat the consumer as an outcome of the global food system, rather than a central component of it. Nonetheless, in order to address some[...]Article
F. Philippe ; E. Jonas ; L. Vidaud ; D. Piazza-Morel ; M.-P. Arlot ; E. Maldonado ; J.-M. Tacnet |Agriculture, gestion de leau, tourisme, exploitation de la forêt, énergétie, etc., tous les secteurs dactivités de moyenne montagne sont impactés par le réchauffement climatique. Afin d'y faire face, les communautés territoriales mettent en p[...]Article
A. Adham ; J.G. Wesseling ; R. Abed ; M. Riksen ; M. Ouessar ; C. Ritsema |Climate change is believed to have a large impact on water resources system both globally and regionally. It has become a major global issue, especially in developing countries because these are most affected by its impacts. Rainwater harvesting[...]Article
Herbicide application in agricultural systems is currently critically discussed because of its possible adverse effects on the environment and human health. Currently, governments and food industry actors search for solutions to reduce herbicide[...]Article
G. Martel ; S. Aviron ; A. Joannon ; E. Lalechère ; B. Roche ; H. Boussard |Green-way policies in agricultural landscapes focus on ecological continuity between semi-natural elements (hedgerows, permanent grasslands, woods) and landscape heterogeneity. These policies suggest annual crops and temporary grasslands exhibit[...]Article
Despite a constant decline in grassland areas between the 1970s and 2010 at the regional and national scale in France, in particular on lowlands, grasslands have been maintained locally. This raises questions about long-term changes on the farms[...]Article
A redesign process at the farm level may be required for agricultural production systems to evolve in a manner that reduces their environmental and health impacts. This process leads to imagining configurations described as radical because the[...]Article

Ruiz |A decision support tool for sheep farming systems (PASTOR-DSS) was developed to investigate trade-offs between economic and environmental objectives on Spanish dairy sheep farms. The tool combines a hierarchical stochastic simulation model at th[...]Article

Dänhardt |As a part of the greening of the EUs Common Agricultural Policy in 2013, Ecological Focus Areas (EFA) became mandatory for many European farmers, with the aim to enhance on-farm biodiversity. However, their effects on biodiversity have been dis[...]Article
The use of geo-tagged photographs seems to be a promising alternative to assess Cultural Ecosystem Services CESs in respect to the traditional investigation when focusing on the study of the aesthetic appreciation of a protected area or natural [...]Article
Deficit irrigation practices carried out in very high-density olive orchards grown in the Alentejo region of southern Portugal can bring important economic benefits in terms of water savings, yields, and oils. They can also result in serious sal[...]Article

Ronga |Barley is an important cereal crop for the arid and semi-arid Mediterranean environments. Future climate projections show that Mediterranean countries will get drier and hotter. The objectives of the study are to: i) simulate the impacts of diff[...]Article
The aim of the GREDRIP model (Part I) is to provide centralized management of an irrigation network, with a minimum energy cost at the pumping station, based on irrigation scheduling to guarantee crop water requirements in the irrigation network[...]Article
M.-L. Tseng ; A.S.F. Chiu ; C.-F. Chien ; R.R. Tan |The circular economy concept is applied in agro-industrial systems to reduce the losses, wastes and avoidable environmental impacts of food supply chains.
