Mexico has a long tradition of production and consumption of alcoholic beverages, particularly tequila, beer, and mezcal. The Baja California vineyard acreage is veryconcentrated. Less than twenty large vineyards produce almost half of the total grape production in Baja California. In contrast, over 75% of the vineyards are small, less than 20 hectares, and supply 25% of the grape used in wine production. While mechanical harvesting may have economic and technical advantages in other wine regions, Baja California growers argue that manual harvesting increases the quality of wine, as the grapes arrive in better condition at the winery compared with mechanical harvesting. There are about ten institutes of technology or universities around the Baja California wine industry area. The Baja California Wine Route includes other tourist attractions, such as museums, outdoor activities (especially during grape harvest time inAugust and September), and a number of restaurants and hotels geared to tourists.

The present announcement aims to purpose a program for the enduring development of the oasis agronomical system. It has to be done so as to get a highly developing fertility of palm groves and improvement of the resilience ability of the ecosystem. In order to do this, a very accurate diagnosis has to be carried out. It is based on evaluation grids of the biodiversity which requires taking into account various factors: agro-ecological, sociological and economic. This is one of the essential points of the present announcement in order to offer a tool to help make the decision to set up a preservation, restoration and maintenance program of biodiversity. This diagnosis will make it possible to assess the frailties of the agricultural system and the possible future improvements to be made. The design and development of this tool rely on the protection of natural resources and socioeconomic values, which characterizes long-lasting agriculture. This grid consists in quantifying the various components of the oasis agricultural system by giving indicators a numbered mark. Decisions will be made depending on the marked indicators. Methodology consist to make phoenicicultural unities inside date palm oases and each unit will be analyzed from EDAO (Evaluation of Durability of Agroecosystem Oases) grids. Each indicator has capacity to give real assessment of the date palm situation and area research will be axis on weakness parameters. These alteration works would be at the origin of favorable atmosphere of palm groves. © ISHS 2013.

The aim of this study was to evaluate the sustainability of farm irrigation systems in the Cébalat district in northern Tunisia. It addressed the challenging topic of sustainable agriculture through a bio-economic approach linking a biophysical model to an economic optimisation model. A crop growth simulation model (CropSyst) was used to build a database to determine the relationships between agricultural practices, crop yields and environmental effects (salt accumulation in soil and leaching of nitrates) in a context of high climatic variability. The database was then fed into a recursive stochastic model set for a 10-year plan that allowed analysing the effects of cropping patterns on farm income, salt accumulation and nitrate leaching. We assumed that the long-term sustainability of soil productivity might be in conflict with farm profitability in the short-term. Assuming a discount rate of 10% (for the base scenario), the model closely reproduced the current system and allowed to predict the degradation of soil quality due to long-term salt accumulation. The results showed that there was more accumulation of salt in the soil for the base scenario than for the alternative scenario (discount rate of 0%). This result was induced by applying a higher quantity of water per hectare for the alternative as compared to a base scenario. The results also showed that nitrogen leaching is very low for the two discount rates and all climate scenarios. In conclusion, the results show that the difference in farm income between the alternative and base scenarios increases over time to attain 45% after 10. years. © 2012 Elsevier B.V.

Land grabbing is a phenomenon which has been growing over the last decades in developing countries. However, the process is now experiencing a new thrust in terms of land surfaces and geographical areas and showing new traits (different aims of investors, South-South movement, reaction of the civil society, etc.). Arab countries, which strongly depend on food imports and suffer from natural constraints, are very active in the so-called «rush for farmland» especially after the food crisis of 2007-2008. In a context of increasing demand for foodstuffs and energy, with the worsening of hunger in the world and with the shortage of investments, this paper intends to make the point of this controversial phenomenon and to throw down the most important challenges relating to food security.

Many initiatives seek to differentiate specific segments in the olive oil market. Olive oil is a flagship product of the Mediterranean region, and its market is evolving with international legislation on origin and quality. Our objective is to analyze and compare public policies in the olive oil industry, from the literature and from case studies of some Mediterranean producer countries. The analysis demonstrates possible conditions for implementing differentiation policies as well as changing modes of governance of Protected Designation of Origin (PDO) or Protected Geographical Indication (PGI). Strategies to defend origin and quality vary from one country to another, depending on government decisions and the engagement of local actors.

We have experienced a period of great agricultural capacity almost on a global scale, called "the Green Revolution". This is a term used to refer to the remarkable increase in the world agricultural production between the early 1960s and the end of the 1980s. The technological progress experienced in the more developed economies and its transfer to other regions, especially Asia and Latin America, led, at that moment, to the doubling of yields for some cereal crops which are basic for the human diet, like rice, wheat and maize, besides the productivity of other plant species and livestock. This real production boom has been able to meet rising food demand in the past 30 years and has also ensured a certain stability to food prices. What has changed? How can we account for an alarming situation that today goes well beyond the ever-neglected issue of hunger in the world's poor areas? What has compromised the reaching of internationally-agreed goals regarding the war against malnutrition? The international markets for agricultural commodities are the stage on which the new scarcity is shown in all its clarity. The rollercoaster ride of commodity prices fully expresses the tensions between demand and supply which are responsible for price rises. Since for many years these changes have not been perceived or have been at the very least underestimated, in this paper we try to address the impact on food security in Mediterranean Countries of this "new paradigm", emphasizing the most critical aspect drawn from major indicators in the field.
