Productivity is an always-hotly-debated issue within the EU agricultural policymaking, particularly concerning the effect of subsidies distributed via the Common Agricultural Policy (CAP). The cereal sector is under particular political scrutiny[...]
Article
Machine learning (ML) and its branch, deep learning (DL), is rapidly evolving and gaining popularity as it outperforms other, more traditional methods in different areas of agriculture. However, ML and DL techniques must be correctly applied to [...]
Article
Climate change is a challenging fact influencing diverse sectors in society including the agricultural one, which is heavily dependent on natural resources and climate. In the Mediterranean region, climate change-related increases in air tempera[...]
Article
A.C. Sánchez ; H.N. Kamau ; F. Grazioli ; S.K. Jones |Diversified farming systems are promoted as a pathway to more sustainable agricultural production. Yet widescale adoption may be slow because of uncertainty about the viability of farmer livelihoods on diversified farms and entrenched perception[...]
Article
Climate change is impacting on the agricultural sector in several ways, and the effects on yields are generally among the most observable ones. Open fields crops, such as cereals, are very vulnerable to climate change. We study the historical da[...]
Article
F. Chemak ; H. Mazhoud ; Z. Rached ; A. Gara ; R. Rahmeni ; H. Ghannem |In Tunisia, the development of the irrigated cereal sector plays a key role in the mitigation of the fluctuation of the rainfed production and to ensure a minimum of production. However, the archived yields remain under the expected potential pe[...]

Vialatte |Farming intensity and landscape heterogeneity influence agrobiodiversity and associated ecological functions. The relative contributions of these agroecosystem components to agricultural production remain unclear because of inter-relations and w[...]
Article
One important issue faced by wheat producers is temporal and spatial yield variation management at a within-field scale. Vegetation indices derived from remote-sensing platforms, such as Landsat, can provide vital information characterising this[...]
Article
Agricultural systems are constantly stressed due to higher demands for products. Consequently, water resources consumed on irrigation are increased. In combination with the climatic change, those are major obstacles to maintaining sustainable de[...]
Article
Using several energy returns on investment indicators (multi-EROI), this article analyses the socioecological transition of an agroecosystem in the western Mediterranean on the island of Mallorca (Spain) over a period of 150 years which saw a ch[...]

A. Tomaz ; J.F. Palma ; T. Ramos ; M.N. Costa ; E. Rosa ; M. Santos ; L. Boteta ; J. Dôres ; M. Patanita |The evaluation of the role of different agronomic strategies in achieving sustainable wheat yields under variable Mediterranean climate conditions may involve the use of resource-use indicators that combine productivity and environmental impact.[...]
Article
This paper aims to analyse the technical efficiency (TE) of dairy farms and find its determinants. To accomplish this problem, the Stochastic Frontier Analysis was applied. The data were obtained from the Farm Accountancy Data Network database f[...]
Article
N. Guiomar ; S. Godinho ; M. Rivera ; T. Pinto-Correia ; R. Machado ; M. Czekaj ; E. Tyran ; J. Puchala |Recent findings on the contribution of smallholders to global food production and security challenge the values used in several reports of international organizations. The skewed distribution of the number of farms and the agricultural area by f[...]

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
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[...]
