The Indian Ocean Experiment (INDOEX) was an international, multiplatform field campaign to measure long-range transport of air pollution from South and Southeast Asia toward the Indian Ocean during the dry monsoon season in January to March 1999. Surprisingly high pollution levels were observed over the entire northern Indian Ocean toward the Intertropical Convergence Zone at about 6°S. We show that agricultural burning and especially biofuel use enhance carbon monoxide concentrations. Fossil fuel combustion and biomass burning cause a high aerosol loading. The growing pollution in this region gives rise to extensive air quality degradation with local, regional, and global implications, including a reduction of the oxidizing power of the atmosphere.

Species distribution models (SDMs) provide realistic scenarios to explain the influence of bioclimatic variables on plant pathogen distribution. Diplodia sapinea is most harmful to plantations of both exotic and native pine species in Italy, causing economic consequences expecially to edible seed production. In this study, we developed maximum entropy models for D. sapinea in Italy to reach the following goals: (i) to carry out the pathogen's first geographical distribution analysis in Italy and determine which ecogeographical variables (EGVs) may influence its outbreaks; (ii) to detect the effect of climate change on the potential occurrence of disease outbreaks by 2050 and 2070. We used Maxent ver. 3.4.0 to develop SDMs. We used six global climate models (BCC-CSM1-1, CCSM4, GISS-E2-R, MIROC5, HadGEM2-ES and MPI-ESM-LR) for two representative concentration pathways (4.5 and 8.5) and two time projections (2050 and 2070) to detect future climate projections of D. sapinea. The most important EGVs influencing outbreaks were land cover, altitude, mean temperature of driest and wettest quarter, precipitation of wettest quarter, precipitation seasonality and minimum temperature of coldest month. The distribution of D. sapinea mostly expanded in central and southern Italy and shifted in altitude upwards on average by ca. 93m a.s.l. Moreover the fungus expanded the range where disease outbreaks may be recorded in response to an increase in the mean temperature of wettest and driest quarter by ca. 1.9 C and 5.8 C, respectively in all climate change scenarios. Precipitation of wettest quarter did not differ between current and any of future models. Under different climate change scenarios D. sapinea's disease outbreaks will be likely to affect larger areas of pine forests in the country, probably causing heavy effects on the dynamics and evolution of these stands or perhaps constraining their survival.

Corporate social performance (CSP) is assumed to have a positive impact on macroeconomic sustainability, but empirical evidence of this impact is absent in the literature. The objective of this paper is to investigate the macro impacts of CSP. We first establish a conceptual framework on the relationship between CSP at the individual business level and sustainability at the macro level. Next, we empirically test the relationship between (averaged) CSP scores and greenhouse gas emissions at the macro level for 22 countries during 20042011. We use Granger causality tests to check for Granger causality. The estimation results show that CSP reduces greenhouse gas emissions, but the long-term effect is rather modest.

Estuaries are among the most valuable aquatic systems by their services to human welfare. However, increasing human activities at the watershed along with the pressure of climate change are fostering the co-occurrence of multiple environmental drivers, and warn of potential negative impacts on estuaries resources. At present, no clear understanding of how coastal ecosystems will respond to the non-stationary effect of multiple drivers. Here we analysed the temporal interaction among multiple environmental drivers and their changing priority on shaping phytoplankton response in the Bahía Blanca Estuary, SW Atlantic Ocean. The interaction among environmental drivers and the number of significant direct and indirect effects on chlorophyll concentration increased over time in concurrence with enhanced anthropogenic stress, changing winter climate and wind patterns. Over the period 1978-1993, proximal variables such as nutrients, water temperature and salinity, showed a dominant effect on chlorophyll, whereas in more recent years (1993-2009) climate signals (SAM and ENSO) boosted indirect effects through its influence on precipitation, wind, water temperature and turbidity. Turbidity emerged as the dominant driver of chlorophyll while in recent years acted synergistically with the concentration of dissolved nitrogen. As a result, chlorophyll concentration showed a significant negative trend and a loss of seasonal peaks reflecting a pronounced reorganisation of the phytoplankton community. We stress the need to account for the changing priority of drivers to understand, and eventually forecast, biological responses under projected scenarios of global anthropogenic change.

Legumes have unique mechanisms to respond to nutrient deficiencies that can be considered as important advantages for agricultural purposes. The preponderance of plant-based protein is on the rise, and the market value of protein crops is expected to be worth billions by 2025. To match the global demand for plant-based products, crops productivity must be ensured; however, this might be impaired either by environmental or anthropogenic pressures that lead to soil nutrient disturbance. The responses activated by legumes to nutrient deficiencies and the mechanisms they utilize to adapt to such conditions will be discussed in this chapter. The study of these factors enables breeding programs specific for legumes and crop improvement. Understanding legumes responses also allows for a better management of agricultural practices and the adoption of more sustainable methods. It is important to reflect on the impact of climate change and intensive farming on food quality and on the future of agriculture, and this chapter contributes with important facts about the role of legumes in our current scenario.

Artículos en revistas Este estudio analiza cómo las estrategias de responsabilidad social corporativa ambiental (ECSR) contribuyen a mejorar la innovación entre las pequeñas y medianas empresas (PYMES) mediante el desarrollo de recursos tecnológicos. Probamos nuestras hipótesis durante un período de ocho años utilizando un panel de 2.405 pymes industriales en España. Encontramos empíricamente que ECSR impulsa la construcción de los recursos tecnológicos de las empresas, lo que resulta en una mejora de su esfuerzo tecnológico o I + D y resultados en términos de innovación de productos y procesos. ECSR intensifica la innovación para empresas innovadoras y cataliza el inicio de la innovación para empresas que antes no innovaban, y los efectos resultantes se mantienen en el tiempo. Contribuimos a la literatura analizando los efectos de ECSR en la promoción de la innovación de las empresas más allá de la conocida influencia en la innovación verde. Además, examinamos el área de investigación descuidada de las estrategias ambientales de las PYME. Nuestros hallazgos fortalecen el valor innovador instrumental de ECSR, específicamente para las PYMES. This study analyzes how environmental corporate social responsibility (ECSR) strategies contribute to enhancing innovativeness among small and medium-sized enterprises (SMEs) by developing technological resources. We test our hypotheses over an eight-year period using a panel of 2,405 industrial SMEs in Spain. We empirically find that ECSR drives the building of firms’ technological resources, which results in an enhancement of their technological effort or R&D and outcomes in terms of product and process innovation. ECSR intensifies innovation for innovative firms and catalyzes the inception of innovation for previously non-innovating firms, and the resultant effects are sustained over time. We contribute to the literature by analyzing the effects of ECSR in promoting the innovation of firms beyond the well-known influence on green innovation. Further, we examine the neglected research area of the environmental strategies of SMEs. Our findings strengthen the instrumental innovative value of ECSR, specifically for SMEs. info:eu-repo/semantics/publishedVersion
