“…Despite this, our observations clearly have extremely important implications with respect to global food security, as the exposure of crop plants to UV‐B irradiance has increased massively in recent years, particularly as a result of the recent thinning of the ozone layer (Callaghan et al. , 2004; Isaksen et al. , 2009).…”

SUMMARYBecause of ever-increasing environmental deterioration it is likely that the influx of UV-B radiation (280-320 nm) will increase as a result of the depletion of stratospheric ozone. Given this fact it is essential that we better understand both the rapid and the adaptive responses of plants to UV-B stress. Here, we compare the metabolic responses of wild-type Arabidopsis with that of mutants impaired in flavonoid (transparent testa 4, tt4; transparent testa 5, tt5) or sinapoyl-malate (sinapoylglucose accumulator 1, sng1) biosynthesis, exposed to a short 24-h or a longer 96-h exposure to this photo-oxidative stress. In control experiments we subjected the genotypes to long-day conditions as well as to 24-and 96-h treatments of continuous light. Following these treatments we evaluated the dynamic response of metabolites including flavonoids, sinapoyl-malate precursors and ascorbate, which are well known to play a role in cellular protection from UV-B stress, as well as a broader range of primary metabolites, in an attempt to more fully comprehend the metabolic shift following the cellular perception of this stress. Our data reveals that short-term responses occur only at the level of primary metabolites, suggesting that these effectively prime the cell to facilitate the later production of UV-B-absorbing secondary metabolites. The combined results of these studies together with transcript profiles using samples irradiated by 24-h UV-B light are discussed in the context of current models concerning the metabolic response of plants to the stress imposed by excessive UV-B irradiation.

“…Finally, there was an additional resource attribute that greatly facilitated regulation, which is alluded to by our choice to group all ODS into a single category. ODS include a wide range of anthropogenic chemicals such as CFCs, HCFCs, and carbon tetrachloride that interact with ozone in the atmosphere and ultimately lead to its dissociation and the loss of ozone protection (Isaksen et al 2009). However, their effects vary as a result of chemical differences that affect their level of reactivity and atmospheric residence time (Pyle et al 1992).…”

Governing the invisible commons: Ozone regulation and the Montreal Protocol

Abstract:The Montreal Protocol is generally credited as a successful example of international cooperation in response to a global environmental problem. As a result, the production and consumption of ozone-depleting substances has declined rapidly, and it is expected that atmospheric ozone concentrations will return to their normal ranges toward the end of this century. This paper applies the socialecological system framework and common-pool resource theory to explore the congruence between successful resolution of small-scale appropriation problems and ozone regulation, a large-scale pollution problem. The results of our analysis correspond closely to past studies of the Protocol that highlight the importance of attributes such as a limited number of major industrial producers, advances in scientific knowledge, and the availability of technological substitutes. However, in contrast to previous theoretical accounts that focus on one or a few variables, our analysis suggests that its success may have been the result of interactions between a wider range of SES attributes, many of which are associated with 338Graham Epstein et al.successful small-scale environmental governance. Although carefully noting the limitations of drawing conclusions from the analysis of a single case, our analysis reveals the potential for fruitful interplay between common-pool resource theory and large-scale pollution problems.

Anthropogenic Chlorofluorocarbons (CFCs) compelled stratospheric ozone reduction is one of the significant global environmental issues of this era. Ozone acts as a life saviour in the stratosphere whereas the same plays a role as a secondary air pollutant at tropospheric levels. This review encompasses studies involving the science of ozone destruction with an emphasis on chemical processes involved, minimum ozone features, ozone hole area characteristics, various Ozone Depleting Substances (ODSs), consequences of reduced stratospheric ozone levels, and the different executed international commitments to restrain ozone depletion. It has been perceived that the decrease in stratospheric ozone volume gives away extensively to climate change such as through ozone chemistry fluctuations of polar annular modes and its Greenhouse Gas (GHG) features. Different international ozone layer protection agreements have been performing a major role in limiting stratospheric ozone depletion thereby its adverse effects, and specifically Montreal protocol has been a great success to this point.
