Adopting sustainable irrigation technologies in Italy: a study on the determinants of inter- and intra-farm diffusion
2023
This paper analyses the drivers for adopting irrigation systems with water conservation and saving technologies (WCSTs) by Italian farmers. The agricultural sector in Italy, like in other Mediterranean countries, suffers from water scarcity and water endowment variability. Water resources play a decisive role in agricultural production and in implementing large-scale WCSTs capable of improving the resilience of the whole agricultural sector. This study uses a microeconomic panel data approach to estimate farmers' decisions in adopting (inter-farm) sustainable irrigation technologies and assesses the intensity of (intra-farm) water-saving practices. Our analysis identifies the main determina…
KLUM@GTAP: Introducing biophysical aspects of land-use decisions into a general equilibrium model: A coupling experiment
2006
In this paper the global agricultural land use model KLUM is coupled to an extended version of the computable general equilibrium model (CGE) GTAP in order to consistently assess the integrated impacts of climate change on global cropland allocation and its implication for economic development. The methodology is innovative as it introduces dynamic economic land-use decisions based also on the biophysical aspects of land into a state-of-the-art CGE; it further allows the projection of resulting changes in cropland patterns on a spatially more explicit level. A convergence test and illustrative future simulations underpin the robustness and potentials of the coupled system. Reference simulat…
Panorámica de la problemática medioambiental en el mundo y en España
2008
As energy resources become scarce and pollution increases, fundamental and often irreversible changes are affecting our global ecosystem, and these changes are already having an influence on countries’ potential for economic growth and development. In this article we examine the principal environmental problems worldwide and how such problems are affected by inequality between countries. In Spain’s case, the basic problems are greenhouse gas emissions, problems relating to water management and issues concerning territory and biodiversity. We also call for the application of economic funding mechanisms to implement environmental policies.
Cambio climático y sustentabilidad económica y social: implicaciones sobre el bienestar social
2008
This article puts forward an explanation of climate change within the context of global change. Climate change can be seen as the spearhead; as a manifestation of the increasing unsustainability of planet Earth. We consider some of the effects of this change, examining its uneven impact on developed and under-developed countries. We then put forward various proposals of how to deal with climate change, highlighting Socolow’s theory in particular. Lastly, we move on to the debate raised by climate change, its impact and possible strategic steps to remedy the situation within the context of environmental sustainability. This will probably lead to a new economic, social and environmental parad…
Enabling leadership promotes a positive working climate
2013
This study looks for current information about factors related to educational leadership that help to promote a positive working climate and which may ultimately influence the employees' overall well-being at work. The study focuses on finding out what is the role of open interaction for the development of a positive working climate. Crucial information about well-being promoting leadership practices is needed in the Finnish context. Previous research shows that employees' experiences of well-being at work in educational organizations vary. Promoting employee well-being has become a crucial leadership issue in the Finnish society. Leadership training has been found to have a key position in…
Up with ecology, down with economy? : The consolidation of the idea of climate change mitigation in the global public sphere
2018
Building on theories of valuation and evaluation, we develop an analytical framework that outlines six elements of the process of consolidation of an idea in the public sphere. We then use the framework to analyse the process of consolidation of the idea of climate change mitigation between 1997 and 2013, focusing on the interplay between ecological and economic evaluations. Our content analysis of 1274 articles in leading newspapers in five countries around the globe shows that (1) ecological arguments increase over time, (2) economic arguments decrease over time, (3) the visibility of environmental nongovernmental organizations as carriers of ecological ideas increases over time, (4) the …
To act or not to act : Debating the climate change agenda in the United States Congress
2020
Most climate change actions take place in the international context in terms of multilateral negotiations and accords or in bilateral agreements between heads of the state. Parliaments or legislatures such as the United States Congress are in a crucial position when it comes to converting agreements or aims to action in domestic politics. The United States has played a volatile role in international negotiations on climate change. From categorically rejecting the Kyoto protocol during the George W. Bush administration, President Barack Obama announced that the United States would join the Paris Climate Accord prior to President Donald J. Trump's announcement of the withdrawal of the United …
Replacing short-haul flights with land-based transportation modes to reduce greenhouse gas emissions: the case of Finland
2019
Even though air travel often provides the fastest transport option, it also has the highest climate impact. Especially on long-haul trips, an aircraft usually represents the only feasible option. Nevertheless, aircraft are more often used on short-haul routes as well. It is the short-haul flights that produce the highest emissions per passenger. These are also the ones that could be replaced the most easily by land-based transportation modes. This study investigates the greenhouse gas emissions reduction potential of replacing short-haul flights with train, coach and car travel within Finland while also taking into account real travel times from door to door. Our results showed that replaci…
The toughest animals of the Earth versus global warming: Effects of long-term experimental warming on tardigrade community structure of a temperate d…
2021
Abstract Understanding how different taxa respond to global warming is essential for predicting future changes and elaborating strategies to buffer them. Tardigrades are well known for their ability to survive environmental stressors, such as drying and freezing, by undergoing cryptobiosis and rapidly recovering their metabolic function after stressors cease. Determining the extent to which animals that undergo cryptobiosis are affected by environmental warming will help to understand the real magnitude climate change will have on these organisms. Here, we report on the responses of tardigrades within a five‐year‐long, field‐based artificial warming experiment, which consisted of 12 open‐to…
Environmental citizenship in geography and beyond
2020
The need for wider action against environmental problems such as climate change has brought the debate about the role of citizen to the political, practical, and scientific domains. Environmental citizenship provides a useful tool to conceptualize the relation between citizenship and the environment. However, there exists considerable variation in the ways environmental citizenship is understood regarding both the aspect of citizenship and the relationship to the environment. In this article, we review the literature on environmental citizenship and investigate the evolution of the concept. The article is based on a literature search with an emphasis on geographical research. The concept of…
