“…The reduction of water into simple numerical values of quantity implies that it has uniform qualities and as such can be easily exchanged with little effect. This is counter to an understanding of water as informed by contemporary science (Shand et al , 2017) and environmental philosophies (Mathews, 2001), which focus on the qualities and interactions between species and aspects of the ecology. In contrast, the quantitative nature of corporate discussion about water is a relatively narrow focus which omits the most crucial aspects of the role water plays in the environment and therefore enables a sense of distance.…”

Purpose This paper aims to examine the role numbers play in corporate environmental reporting. To deeply examine the ontological meanings of enumeration in the context of nature, the histories of number and accounting are explored. Some key tropes emerge from these histories, namely, distancing and control. Design/methodology/approach To explore some of the implications of quantifying nature, three years of environmental reports of ten companies from the ASX200 are analysed through a Barthsian lens. Examples of enumerating nature are highlighted and explored in terms of what this means for the corporate relationship with nature. This study has focussed on some specific aspects of nature that are commonly counted in corporate environmental reporting: carbon, energy, water, biodiversity and waste. This study explores how monetisation and obfuscation are used and how this informs the myth that nature is controllable. Findings This study finds that quantifying nature constructs a metaphorical distance between the company and the natural world which erodes the sense of connection associated with an authentic care for nature. These findings are critical in light of the detrimental impact of corporate activity on the natural world. The reports themselves, while promoted as a tool to help mitigate damage to the natural environment, are implicitly perpetuating its harm. Research limitations/implications Given the extent to which companies are responsible for environmental damage and the potential capacity embedded in corporate communications, better understanding the implications of quantifying nature could powerfully instigate a new but necessary approach to nature. Originality/value The insights of this paper are relevant to those aiming to improve the underpinning approaches used in corporate environmental reporting. This paper provides new understandings of the ways quantitative expression of environmental values constructs the myth that nature is controllable.

“…Intensi ed rainfall and drought have an important impact on the amount of land use for water and water quality. Shand et al, (2017) argue that climate variability is a key driver of dewatering in wetland systems. Superimposed on this are the effects of climate change or variability in terms of amount, timing and distribution of rainfall and discharge, and that, these do not work in isolation (Shand et al, 2017).…”

River floodplains such as the Barotse Flood Plain (BFP) in Western Zambia, provide a large number of ecosystem services and economic value for the inhabitants. Yet, in spite of its importance, the flood plain has been vulnerable to drivers of land use change suggestive of potential wetland degradation. This study aimed at determining the extent of land use change in the wetland of BFP in the selected years between 1980 to 2020 and identifying, and assessing drivers of land use change in the wetlands of BFP using satellite data. The study utilized both secondary and primary data sources. Primary data was collected using interview schedule, key informants’ interviews, Participatory Rural Appraisal and field observations. The Raosoft random sample calculator was used to determine the sample size of heads of households from 9 districts that are found within the Barotse Flood Plain. Then, proportional sample size per district out of 270 was calculated. It was found that there is land use change in the wetlands of BFP caused by many driving factors such as biophysical, economic, infrastructure development, technological, demographic, agriculture and others. The study recommended strategies such as the Government of Zambia, traditional leaders and other stakeholder should embark on protection and conservation of BFP. In addition, new policies on land use and water resources management in the wetlands such regularly monitoring of all activities taking place in and around the wetland of BFP by Water Resources Management Authority should be explored.

Optimum water supplement strategy to restore reed wetland in the Yellow River Delta

et al. 2017

In order to supply optimum water to restore reed wetlands used for bird habitats, a field investigation and greenhouse experiment were conducted. Three water supplementation stages (early stage at 20 May, middle stage at 20 July and later stage at 20 September, respectively) and five depths (0, 10, 15, 20 and 35 cm over the surface, respectively) were established, with three replicates for each treatment combination. Reed growth characteristics (survival rate, height, density and biomass) and soil properties of field investigation and experiment were recorded to determine the impacts of water supplementation on reed wetland restoration. The field investigation showed that reeds in natural wetlands grow better than those in degraded wetlands and soil properties in degraded wetlands were significantly different from soils in natural wetlands. With freshwater supplementation, reed growth characteristics and soil properties greatly improved. As water depth increased, reed growth decreased gradually. Reeds grew best in shallow water depth (≦10cm) than in the greater flooding depths. Saturated soils with no standing water at the early stage of reed growth increased reed survival and water depth can be increased as the reeds grow. During the process of water supplementation, soil salinity was reduced significantly. Soil salinity was reduced dramatically at early and middle stages of reed growth, but it increased slightly at the later stage. Soil pH increased greatly during the experiment. Soil total nitrogen (TN) and total organic carbon (TOC) showed contrasting changes, with soil TN decreasing and TOC increasing. To best manage reed wetlands restoration, we suggest saturating wetland in the spring to stimulate reed germination, increasing surface water depth up to 15cm at the stage of reed rapid growth, and then reducing water depth during the later growth stage.
