Glyphosate isopropylamine and trifluralin are herbicides widely used in Turkish agriculture. The recommended field dose (RFD) (480 g of active ingredient l for both glyphosate and trifluralin) and 2 × RFD of these herbicides were added to the soil of olive trees (Olea europaea L., Oleaceae) growing on the Çukurova University Campus (Adana) under Mediterranean climate conditions in order to dete...

The paper analyses characteristics of vertical relationships of organic supply chains with a specific focus on the processing and retailing sectors. The analysis takes into account different regions of the EU Mediterranean area. Data were collected through interviews using an ad hoc questionnaire. The survey was based on a sample of 306 firms, including processors and retailers. The analysis re...

Spanish holm oak (Quercus ilex subsp. ballota) open woodlands (dehesas) maintain a high diversity of plants and animals compared to other forested Mediterranean habits, but little is known about the responses of epiphytic lichens to different management regimes that are applied to this woodland type. The present study was carried out in central-southern Spain and included four management regime...

In this work, an innovative cellulose-based superabsorbent polymer (SAP) was experimentally assessed as an environmentally friendly alternative to acrylate-based SAPs, for the optimization of water consumption in agriculture. The cellulose-based SAP was synthesized and tested for its swelling capability in different aqueous media. The effectiveness of the SAP in agricultural applications was th...

Early human societies and their interactions with the natural world have been extensively explored in palaeoenvironmental studies across Central and Western Europe. Yet, despite an extensive body of scholarship, there is little consideration of the environmental impacts of proto-historic urbanisation. Typically palaeoenvironmental studies of Bronze and Iron Age societies discuss human impact in...

Europe has experienced a stagnation of some crop yields since the early 1990s as well as statistically significant warming during the growing season. Although it has been argued that these two are causally connected, no previous studies have formally attributed long-term yield trends to a changing climate. Here, we present two statistical tests based on the distinctive spatial pattern of climat...

SALTIRSOIL (SALTs in IRrigated SOILs) is a model for the medium to long term simulation of soil salinity in irrigated, well-drained lands. Once the algorithms were verified, the objective of our study was to validate SALTIRSOIL under one of several water quality and management scenarios in Mediterranean agriculture. Because drip and surface are the most common irrigation systems in irrigated ag...

Two related land use change dynamics characterise the Guadalent!ın basin (southeast Spain) as one of the most severe cases of desertification in Europe: (1) expansion of highly productive irrigated agriculture in the valley, and (2) intense contemporary changes in the surrounding impoverished dry lands. On the basis of documented information, we trace the effects of past policies on these dynam...

Cold treatment periods, and associated levels of quarantine security, that maximize net US welfare under USDA’s current medfly detection and control program are examined using a deterministic bioeconomic optimization model. As anticipated, the efficient level of quarantine security is shown to increase with indices of medfly pressure (initial infestation rates) in areas in which the medfly is k...
