Models can provide a structured way to think about adoption and provide a method to investigate the impacts of different factors in the adoption process. With at least 70 years of research in the adoption of agricultural innovations, there has b[...]Article
Agricultural land expansion and intensification, driven by human consumption of agricultural goods, are among the major threats to environmental degradation and biodiversity conservation. Land degradation can ultimately hamper agricultural produ[...]Article
Understanding the soil and hydrologic processes in agricultural watersheds are vital for reliable assessments of water quantity and quality to support integrated river basin management. However, deriving hydrology-relevant information is complic[...]Article
L.F. Dias ; B.A. Aparício ; J.P. Nunes ; I. Morais ; A.L. Fonseca ; A.V. Pastor ; F.D. Santos |Irrigation is essential for a large part of Mediterranean agricultural systems, but scarce resources may cause conflicts between agricultural and domestic uses. These conflicts might be exacerbated by climate change, which could bring a drier cl[...]Article
Models are important tools to integrate ecological and socio-economic knowledge to better understand and manage social-ecological systems. Challenges include, among others, the adequate representation of feedback loops between the socio-economic[...]Article
A. Zezza ; F. DeMaria ; T. Laureti ; L. Secondi |The organic food certification system in Italy, based on the EU legislation, relies on private control bodies (CBs) that are supervised by national authorities. The aim of this paper is to investigate whether it is possible to test for differenc[...]Article
C. Labrousse ; W. Ludwig ; S. Pinel ; M. Sadaoui ; G. Lacquement |In the Mediterranean, climate change and human pressures are expected to significantly impact the availability of surface water resources. In order to quantify these impacts during the last 60 years (19592018), we examined the hydro-climatic an[...]Article
Article
The identification of agricultural adaptation strategies to offset climate change impact requires a detailed knowledge of the response of crop systems under future climatic conditions. To carry out such an analysis for Mediterranean olive orchar[...]Article
D. Cammarano ; D. Cammarano ; D. Ronga ; I. Di Mola ; M. Mori ; M. Parisi |Tomato (Solanum lycopersicum L.) is a globally important vegetable recognized for its positive health benefits. As most of the vegetable production, tomato require significant amount of agronomic inputs. However, recent shifts in climate pattern[...]Article
Integrating stakeholder views and system dynamics to assess the waterenergyfood nexus in Andalusia
A nexus approach can support the transition to sustainability by addressing trade-offs and pursuing synergies to improve water, energy, and food security. In this paper, a participatory system dynamics model was developed to identify and assess [...]Article
A. Elbeltagi ; J. Deng ; K. Wang ; A. Malik ; S. Maroufpoor |Crop evapotranspiration (ETc) is one of the most basic components of the hydrologic cycle that is effective in irrigation system design and management, water resources planning and scheduling, and hydrologic water balance. Thus, precise estimati[...]Article
Water management projects have an important role in regional environmental protection and socio-economic development. Environmental policies, strategies, and special measures are designed in order to balance the use and non-use values arising fo[...]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
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
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
This "perspectives" article draws upon close to 50 years of experience in the development and application of crop, soil and farm systems models in pursuit of enhanced productivity and sustainability of agricultural systems. The scientific founda[...]Article
Agricultural specialization has disconnected crop and livestock production in many farms and regions. As a result, crop farms are deficient in nitrogen to fertilize their crops, while livestock farms are deficient in proteins to feed their anima[...]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
Turkey's many and varied landscapes face the challenge of degradation and ultimately desertification due to soil problems that include organic matter deficiency, salinity-alkalinity, compaction and erosion and the loss of biological productivity[...]Article
C. Dibari ; S. Costafreda-Aumedes ; G. Argenti ; M. Bindi ; F. Carotenuto ; M. Moriondo ; G. Padovan ; A. Pardini ; N. Staglianò ; C. Vagnoli ; L. 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
I. Coteur ; H. Wustenberghs ; L. Debruyne ; L. Lauwers ; F. Marchand |A multitude of farm-level sustainability assessment tools (SATs) exists, reflecting a variety of agricultural practices and sustainability perceptions. Tools differ and insight is lacking about how they match with farmers' needs. This paper exam[...]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
