Adapting agriculture to climate change AgEcon
Iglesias, Ana; Quiroga, Sonia; Diz, Agustin; Garrote, Luis.
We evaluate the potential impacts and measure the potential limits of adaptation of agriculture to climate change. Pressures on land and water resources are expected to intensify existing risks in low latitude areas – e.g., South-East Asia deltas – and in regions with current water scarcity – e.g. Mediterranean, and create new opportunities in some northern temperate areas – e.g., Northern Russia, Northern Europe. The need to respond to these risks and opportunities is addressed by evaluating the costs and benefits of a number of technical and policy actions. The discussion aims to assist stakeholders facing the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

Crop Production Functions for Analysis of Global Change Impacts in Spain AgEcon
Gomez, Sonia Quiroga; Iglesias, Ana.
The goal of this paper is to increase the capacity of the agriculture sector to understand and respond to the climate variability, by reducing the uncertainty of the farmers over decisions that are affected for meteorological conditions. To study the yield responses to meteorological variables in the past is crucial to understand the vulnerability of the agriculture to the climate change in the future. We have estimated regression models where the historical yields have been put in dependence of variables that can represent main drivers of global change, such as climate variables and technological ones. In this context we evaluate its influence over the yields. Among the conclusions we find that the adaptation to climate change requires challenges in which...

Economic Feasibility of Organic Farms and Risk Management Strategies AgEcon
Medina, Felipe; Iglesias, Ana.
Organic farmers must face different risks than conventional farmers Due to the special features of management of their productive system, and due to the specific characteristics of their cultivations. This study analyses the specific risks that organic farmers must manage as well as the different strategies that there are developing nowadays. Even if the Spanish farmers rely on the insurance system to manage their risks, today organic farmers do not have specific insurance products to manage them. The methodology and results presented in this study include a risk analysis carried out by evaluating statistical, probabilistic, and stochastic properties of the organic production data. We evaluate and discuss the aspects of our study that relate to other...

Economic valuation of the impacts of climate change in agriculture in Europe AgEcon
Quiroga, Sonia; Iglesias, Ana.
The objective of this study is to provide a European assessment of the potential effects of climate change on agricultural crop production computing monetary estimates of these impacts for the European agricultural sector. The future scenarios incorporate socio economic projections derived from several SRES scenarios and climate projections obtained from global climate models and regional climate models. The quantitative results are based simulations using the GTAP general equilibrium models system that includes all relevant economic activities. The estimated changes in the exports and imports of agricultural goods, value of GDP and crop prices under the climate and socio-economic scenarios show significant regional differences between northern and...

Impacts and adaptive capacity as drivers for prioritizing agricultural adaptation to climate change in Europe AgEcon
Schlickenrieder, Jeremy; Quiroga, Sonia; Diz, Agustin; Iglesias, Ana.
In the face of likely climate change impacts policy makers at different spatial scales need access to assessment tools that enable informed policy instruments to be designed. Recent scientific advances have facilitated the development of improved climate projections, but it remains to be seen whether these are translated into effective adaptation strategies. This paper uses existing databases on climate impacts on European agriculture and combines them with an assessment of adaptive capacity to develop an interdisciplinary approach for prioritising policies. It proposes a method for identifying relevant policies for different EU countries that are representative of various agroclimatic zones. Our analysis presents a framework for integrating current...

The objective of this study is to provide monetary estimates of the impacts of climate change in European agricultural sector. The future scenarios incorporate socio-economic projections derived from several socio-economic scenarios and experiments conducted using global climate models and regional climate models. The quantitative results are based simulations using the GTAP general equilibrium models system that includes all relevant economic activities. The estimated changes in the exports and imports of agricultural goods, value of GDP and value of world supply under the climate and socio-economic scenarios show significant regional differences between northern and southern European countries. The simulations were based on crop productivity changes that...

Projections of economic impacts of climate change in agriculture in Europe AgEcon
Quiroga, Sonia; Iglesias, Ana.
RESUMEN This study provides monetary estimates of the impacts of climate change in European agriculture. Future scenarios are derived from several socio-economic scenarios and experiments conducted using global climate moedls and regional climate models. The economic valuation is conducted by using GTAP general equilibrium model across simulations based on crop productivity changes that consider no restrictions in the volume of water available for irrigation in current irrigated areas or in the application of nitrogen fertilizer. Thus the results should be considered optimistic from the production point and pessimistic from the environmental point of view. Regional differences between northern and southern European countries are found and the monetary...

Risk management, vulnerability, and risk perception of organic farmers in Spain AgEcon
Medina, Felipe; Iglesias, Ana; Mateos, Carlos.
This study analyses the specific risks that organic farmers must manage. Due to the special features of management of their productive system, and due to the specific characteristics of their cultivations, they must face different risks than conventional farmers. Even if the Spanish farmers rely on the insurance system to manage their risks, today organic farmers do not have specific insurance products to manage them. The methodology and results presented in this study include the following: First, the primary information is compiled after the elaboration of more than 500 questionnaires to organic farmers of diverse Spanish regions. Second, the risk analysis is carried out by evaluating statistical, probabilistic, and stochastic properties of the...
