Although the Central American countries trade very extensively with the USA, the remarkable growth of their intra-regional exports is prone to create more internal added value for the region. Taking this background into account, we use and compare a standard, perfectly competitive and an imperfectly competitive GTAP CGE model based on the GTAP 9 da...

University Cooperation for Development is an important part of the “third mission” of universities. From a capability approach, this study investigates the perception that Latin-American university teachers, researchers and staff have as recipients of aid, about the effects of long-term university cooperation programmes with universities from the N...

The upland olive groves of Andalusia (Southern Spain) are an example of fragile landscape from an ecological point of view. The wildfire and soil erosion risks that can result in the desertification of the area are the main components of fragility. This paper focuses on the visual quality assessment of this agricultural system as a mean to their ec...

The countries in the Central American region (henceforth CA: Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panamá) have signed multiple trade agreements in the recent past. Sometimes the whole CA worked as a unified agent, for instance vis a vis the United States or the European Union. In other cases, some individual countries took th...

Russia, Ukraine and Kazakhstan (RUK) are major players in the international grain markets and their exports help to improve global grain availability and hence food security. However, during the last decade the availability of RUK grain exports was repeatedly diminished by harvest failures and further reduced by the introduction of export restricti...

In this paper the Analytic Hierarchy Process (AHP) multicreteria evaluation method has been used to evaluate 4 different competing management options at olive plantations (Olea europaea L.) in mountain areas. All the evaluation process is integrated into a Geographical Information System (GIS) that gave possibility to allocate each of the options g...

Analysis of the joint production of private and public goods (PGs) by farming activities is a fertile research field. These joint production processes are typically characterised by a high level of complexity derived from the intense relationship between the production of both kinds of outputs. An integrated approach is strongly recommended for the...

The analysis of the joint production of private and public goods from farming activities is a fertile research field in agricultural and environmental economics aiming at supporting public decision-making regarding a better governance of the agricultural sector. These joint production processes are typically characterized by a high level of complex...

El apoyo a la toma de decisiones de problemas complejos, como el de la adecuada producción de bienes y servicios públicos por parte de la agricultura, supone un importante desafío para los economistas agrarios. En efecto, las numerosas relaciones existentes entre las producciones de estos bienes y servicios y los bienes privados (productos agrarios...

Ukraine and the EU are currently negotiating a deep and comprehensive free trade agreement (FTA). Such a FTA can be expected to comprise opportunities as well as challenges for both the EU and Ukraine and to have an impact on agricultural markets. This article provides a model-based quantitative assessment of the potential impact of a FTA on agricu...

This paper examines the effect of the future developments of Russian and Ukrainian agricultural sectors and their impact on the world market prices for arable crops. Employed in the study is AGMEMOD, a partial equilibrium economic model of EU agriculture at the Member State level that has been extended by Russia and Ukraine to gain quantitative ins...

This report gives an overview on the Ukrainian agri‐food sector and provides an outlook for the developments in agricultural markets for Ukraine, focussing on the main agricultural commodities. For the purpose of the study a detailed dataset and modelling structure for the main agricultural commodities in Ukraine has been developed and integrated i...

This report presents a summary and the presentations of the expert workshop "Developments in agricultural commodity markets: a special focus on Ukraine, Russia and Kazakhstan". In the workshop specific sessions covered developments and perspectives of the most important agricultural commodity markets (cereals, oilseeds, biofuels, milk and meat). A...

The negotiations on a deep and comprehensive free trade agreement (FTA) between Ukraine and the EU are currently in process. Such a FTA can be expected to imply opportunities as well as challenges for agricultural markets.

En la valorización de los espacios naturales protegidos al menos se pueden distinguir tres tipos de valores: el valor de uso actual, el valor de opción o valor de uso futuro y el valor de existencia. Precisamente este último valor, llamado también valor de no-uso, es el que declaran aquellas personas que no utilizan el recurso ambiental, ni piensan...

que la percepción de calidad escénica depende de las características sociales, culturales y económicas del observador, por ejemplo, el visitante y la población local suelen tener una visión muy diferente del concepto de calidad del paisaje agrario. Esta percepción puede alterarse por la experiencia asociada a la observación, es decir, un paisaje ag...

In the present study we assess the visual quality of these olive plantations based on a survey. Then, the Society’s visual preferences for different types of olive plantations in mountain areas have been integrated into a Geographical Information System (GIS).

The study presents an approach that combined objective information such as sampling or experimental data with subjective information such as expert opinions. This combined approach was based on the Analytic Network Process method. It was applied to evaluate soil erosion risk and overcomes one of the drawbacks of USLE/RUSLE soil erosion models, name...

This study analyzes the suitability of agricultural lands with risk of abandonment for restoration to suitable habitats for animal species of conservation interest. As a case study, the main focus was on olive plantations (Olea europaea L.) of mountainous areas of Southern Spain and the Iberian lynx (Lynx pardinus Temminck, 1827). The method weighs...

This study adopts a two-fold methodological approach to assessing the suitability of olive plantations in mountainous areas for wildlife habitat restoration. Embedding expert judgements through an Analytic Hierarchy Process (AHP) about the effect of specific elements of the landscape on ecological diversity permits the most suitable agricultural ar...

Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative to support the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical app...

The soil erosion risk evaluation is one of the most important exercises in every agricultural territory. Currently a lot of models that deal with this kind of problem are known. However to run these models grate number of the information as an entrance data are required. The situation when there is no enough information is very common in real life....

Due to the reform of the olive oil MCO some olive groves in mountain areas will become non-productive. The abandonment of these cultivated lands will have an effect on several landscape sustainability criteria: biodiversity, soil erosion, fire hazard and visual quality of the rural scene. The first phase of this three years research project has bee...

This paper presents the first results of the initial stages of a three years research project on optimization of the use of agricultural lands subject to risk of abandonment. After devising a physical marginality index for olive cultivation based on soil quality and slope, we estimate an approximate area of 200,000 hectares of marginal olive planta...
