Mota ; B.d.A. Oliveira ; M.L. da Silva |Sustainable production and land use planning are recurring challenges in the agricultural and forestry activities. In this context, a mathematical programming model is proposed that allows for both optimal production planning and its updating, w[...]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
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
C. Font ; R. Padró ; C. Cattaneo ; J. Marull ; E. Tello ; A. Alabert ; M. Farré |In this paper we propose an approach to understand how different farmers goals can contribute to structure cultural landscapes and how the information-as-structure held in energy flows within farm systems can be measured. We start from a histor[...]Article
Social and environmental awareness of consumers force supply chains to be more sustainable. This paper studies the coordination problem for a single manufacturer-single retailer sustainable supply chain model in presence of consumers? environmen[...]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
Recent research studies and policies about innovative solutions to reduce water and energy consumption in food production are briefly reviewed. Options to increase water use efficiency and productivity include soil mulching, drip irrigation, def[...]Article
A certain number of factors can affect the functioning of the distribution chains of large agrifood companies and impact their efficiency. Among them, poor adaptation to fluctuations in demand, imperfect control of production and transport costs[...]Article
Une première phase détude sur les circuits logistiques a été menée par le CTIFL en 2019 et a permis de poser le cadre dans lequel évoluent les fruits et légumes. Il en ressort une grande diversité de cas en termes dorganisation, de nature de c[...]Article
The Egyptian government initiated a development project in 2015 to reclaim 1.5 million acres with the primary goal of increasing agricultural production. Siwa is one of these areas in the Western Desert of Egypt, with 30,000 acres using groundwa[...]Article
One of the most important challenges in any society is the issue of food and water supply. Undoubtedly, agriculture has a major role in water consumption, and grains have the largest use in the food of people. Bread is also an essential commodit[...]Article
M.A. Miranda-Ackerman ; C. Azzaro-Pantel ; A.A. Aguilar-Lasserre ; A. Bueno-Solano ; K.C. Arredondo-Soto |An important contribution to the environmental impact of agro-food supply chains is related to the agricultural technology and practices used in the fields during raw material production. This problem can be framed from the point of view of the [...]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
The inefficiencies observed in current agro-food supply chains, and recent trends in agro-food industry such as consolidation, increase the need for further studies on supply chain management in this field. Models are required for the complex ta[...]Article
