Hope in a hopeless age: environmentalism’s crisis

In this short essay it is argued that recent criticisms portraying the activist environmental movement as overly pessimistic are valid and that the communication of this pessimism to the public at large has been largely counterproductive to the objectives of environmentalists. It is argued that, in contrast to historic assumptions of a ‘progress paradigm’ that epitomized the widely held optimism of the past, the shock tactics and pessimistic media campaigns employed by the activist environmental movement, and the media that capitalizes upon those campaigns, have contributed to the creation of a figurative hopeless age. The key characterization of the hopeless age is the widely held assumption that the future will be worse than the present and that the lives of future generations will be diminished relative to our own. It is argued that the creation of this social-psychological phenomenon is counterproductive to the aims of the environmental movement and that the restoration of a collective vision and message of hope would be far more productive. Lastly, some reasons for a hopeful outlook are suggested.

Environmental Ethics and Biomimetic Ethics: Nature as Object of Ethics and Nature as Source of Ethics

While the contemporary biomimicry movement is associated primarily with the idea of taking Nature as model for technological innovation, it also contains a normative or ethical principle—Nature as measure—that may be treated in relative isolation from the better known principle of Nature as model. Drawing on discussions of the principle of Nature as measure put forward by Benyus (Biomimicry: innovation inspired by nature, Harper Perennial, New York, 1997) and Jackson (Consulting the genius of place: an ecological approach to a new agriculture, Counterpoint, Berkeley, 2010, Nature as measure: the selected essays of Wes Jackson, Counterpoint, Berkeley, 2011), while at the same time situating these discussions in relation to contemporary debates in the philosophy of biomimicry (Mathews in Organ Environ 24(4): 364–387, 2011; Dicks in Philos Technol, doi: 10.1007/s13347-015-0210-2, 2015; Blok and Gremmen in J Agric Environ Ethics 29(2):203–217, 2016), the aim of this paper is to explore the relation between the principle of Nature as measure and environmental ethics. This leads to the argument that mainstream formulations of environmental ethics share the common trait of seeing our ethical relation to Nature as primarily involving duties to protect, preserve, or conserve various values in Nature, and that, in doing so, they problematically either overlook or dismiss as anthropocentric the possibility that Nature may provide measures, understood in terms of ecological standards, against which our own practices, or at least some of them, may be judged—a way of thinking I call “biomimetic ethics”. The practical consequences of this argument are significant. Whereas mainstream environmental ethics has been applied above all to such issues as wilderness preservation, natural resource management, and animal rights and welfare, biomimetic ethics is applicable rather to the question of how we produce, use, and consume things, and, as such, may potentially provide the basic ethical framework required to underpin the transition to a circular, bio-based, solar economy.     

Exposing violences: Using women's human rights theory to reconceptualize food rights

Exposing food violences – hunger,malnutrition, and poisoning from environmentalmismanagement – requires policy action thatconfronts the structured invisibility of theseviolences. Along with the hidden deprivation offood is the physical and political isolation ofcritical knowledge on food violences and needs,and for policy strategies to address them. Iargue that efforts dedicated on behalf of ahuman right to food can benefit from thetheoretical analysis and activist work of theinternational Women's Rights are Human Rights(WRHR) movement. WRHR focuses on women andgirls; the food rights movement operates onbehalf of all people, with an emphasis on thepoor. Both attend to the protection of bodilyintegrity against physical and psychicviolences. Both cope with bodily violences thatare socially privatized and spatiallysegregated from public institutions of relief,that is, they are tacitly omitted from publicdiscourse and purview. Most typically, but notexclusively, these violences unfold in privatehousehold space. Both rights movements mustmobilize political rights to demand economicand social rights and security. I introduce theUnited Nations' early Declaration (1948) andCovenant (1966) language on the human right tofood and review problems of household accessand grassroots engagement that are ``writteninto' this early documentation. An abbreviatedoverview of the WRHR movement describes how thepublic/private and economic/political rightsdichotomies have been critiqued andre-formulated. A case study set in Polandacross the transition from (more) communist to(more) capitalist political economies attemptsto illuminate the discussion through agrounded example.     

From Rio to Johannesburg and Beyond: A long and winding road

This paper analyses the evolution of urban form in two North American metropolitan regions (Portland and Toronto) and asks how more sustainable regional form might come about in the future in these and other urban areas. In the past, dominant patterns of urban form have emerged in such regions at different historical periods. These morphological phases include mid 19th-century grids, streetcar suburb grids, garden suburbs, automobile suburbs and New Urbanist neighbourhoods (which have only recently made an appearance and may or may not become widespread). Judging by the performance of past types of urban morphology, five design values appear particularly important for more sustainable urban form in the future: compactness, contiguity, connectivity, diversity and ecological integration. Although these principles were not well supported by 20th-century development, contemporary movements such as the New Urbanism and Smart Growth re-emphasise them. The example of these two regions indicates that, in the absence of new technological, economic or geographical forces, public sector institutions and urban social movements represent the most likely means to bring about new, more sustainable types of urban form.     

Telos and the Ethics of Animal Farming

The concept of animal welfare in confinement agriculture—and an ethical theory based upon this concept—necessitates an idea of what kind of being it is that fares well and what “well” is for this being. This double-question is at the heart of understanding and adequately defining welfare as qualitatively embedded in the experiencing subject. The notion of telos derives (philosophically) from Aristotle and is a way of accounting for the good life of an animal from the unique speciesness of the animal in question. The first part of the article will address the contemporary philosophical and ethical analysis of animals based upon this Aristotelian idea (Rollin in Animal rights and human morality (1st ed. 1981). Prometheus Books, New York, 2006b). Telos is here employed to illustrate the dimensions of what matters in welfare assessment and ethical evaluation. The second half of the article addresses some of the welfare problems in modern animal agriculture and how they relate to the telos concept. Two main examples are dealt with: Boredom (Wemelsfelder in Mental health and well-being in animals. Blackwell Publishing, Oxford, 2005) is argued as being the suffering of choicelessness in animals that are inherently beings that choose—and loneliness is the suffering of social isolation in animals for whom standing in active relations to others is part of what they are.     

Midas’ Not-So-Golden Touch: On the Demise of Methyl Iodide as a Soil Fumigant in California

The demise of the soil fumigant, Midas, was heralded as a major environmental movement achievement, when Arysta LifeScience eventually deemed it economically non-viable and withdrew from US markets just before resolution of a lawsuit. Building on scholarship that focuses on strategy to understand how social movements sometimes win, we show how activist tactics were able to exploit the missteps of their opponents. These included the unreasonable expectations of Arysta for grower adoptions, the foibles of the director of California's Department of Pesticide Regulation in registering the chemical, and the reluctance of California's strawberry industry to discontinue use of methyl bromide. Although activist tactics, such as public comments and protests, had only a modest impact on the regulatory process, they had a major impact on grower adoptions of the chemical. This, together with a lawsuit that was not going well for the defendants, ultimately led to the withdrawal. Still, there was a great deal of luck involved, especially in the lawsuit in which the judge made rulings and statements favourable to the plaintiffs. Here, ‘scientization’, worked in favour of the movement rather than the industry.     

EFFECTS OF CLIMATE CHANGE ON WATER RESOURCES IN THE DELAWARE RWER BASIN1

ABSTRACT: The effects of potential climate change on water resources in the Delaware River basin were determined. The study focused on two important water-resource components in the basin: (1) storage in the reservoirs that supply New York City, and (2) the position of the salt front in the Delaware River estuary. Current reservoir operating procedures provide for releases from the New York City reservoirs to maintain the position of the salt front in the estuary downstream from freshwater intakes and ground-water recharge zones in the Philadelphia metropolitan area. A hydrologic model of the basin was developed to simulate changes in New York City reservoir storage and the position of the salt front in the Delaware River estuary given changes in temperature and precipitation. Results of simulations indicated that storage depletion in the New York City reservoirs is a more likely effect of changes in temperature and precipitation than is the upstream movement of the salt front in the Delaware River estuary. In contrast, the results indicated that a rise in sea level would have a greater effect on movement of the salt front than on storage in the New York City reservoirs. The model simulations also projected that, by decreasing current mandated reservoir releases, a balance can be reached wherein the negative effects of climate change on storage in the New York City reservoirs and the position of the salt front in the Delaware River estuary are minimized. Finally, the results indicated that natural variability in climate is of such magnitude that its effects on water resources could overwhelm the effects of long-term trends in precipitation and temperature.     

Obligations to animals are based on rights

Some feminist philosophers criticize the idea of human rights because, they allege, it encapsulates male bias; it is therefore misguided, in their view, to extend moral rights to non-human animals. I argue that the feminist criticism is misguided. Ideas are not biased in favour of men simply because they originate with men, nor are ideas themselves biased in favour of men because men have used them prejudicially. As for the position that women should abandon theories of rights and embrace an ethic that emphasizes care: women who made this choice would not so much liberate themselves from the patriarchy as they would conform to its representation of women as emotional, subjective and irrational. There is, then, no good reason to withhold ascribing rights to non-human animals, based on the criticisms of rights made by some feminists.Some of the material in the discussion of the feminist critique of rights originally appeared in my The Case for Animal Rights: A Decade's Passing inA Quarter Century of Value Inquiry: Presidential Addresses of the American Society of Value Inquiry, edited by Richard T. Hull, pp. 451–455. Amsterdam and Atlanta, GA: Rodopi, 1994.

Flooding and the interannual variability of hydrologic quantities in the Missouri River basin

The six mainstem reservoirs in the Missouri River basin (MRB) are managed mainly to prevent flooding from snowmelt and heavy rainfall, a goal for which the interannual variabilities of precipitation ($P$), evapotranspiration ($\mathit{ET}$), and surface air temperature ($T_{\mathrm{air}}$) are vitally important. We tested the hypothesis that under the expected higher variability owing to global climate change, the months with the highest contributions to the interannual variability of $P$, $\mathit{ET}$, and $T_{\mathrm{air}}$ in the MRB will remain unchanged and quantified likely temporal trends in these quantities. Using high-resolution, downscaled Coupled Model Intercomparison Project Phase 5 multi-model ensemble data sets, we compared the multi-year ratio of monthly and annual interannual variability and temporal trends in $P$, $\mathit{ET}$, and $T_{\mathrm{air}}$ during 2011–2020 with three future decades. Results showed that the 6 months with the highest interannual variability in $P$ and $\mathit{ET}$ (April–September) are the same in all four decades. However, for $T_{\mathrm{air}}$, only 4 months (December–March) retain their status as highly variable throughout the four decades; September and October variability is exceeded by the variability in other months. This implies that, compared to $P$ and $\mathit{ET}$, the cyclical change in the probabilities of $T_{\mathrm{air}}$ in the MRB is less stable under future global climate change. This finding can be used to consider the need to alter existing strategies for reservoir release while minimizing the likelihood of aggravating flooding below the reservoirs.     

Ownership property size,landscape structure,and spatial relationships in the Edwards Plateau of Texas (USA): landscape scale habitat management implications

The present research focused on using spatial analysis to determine relationships among land ownership property sizes and landscape structure, with a focus on conservation management implications. Indices and metrics of ownership property sizes and landscape structure were calculated for 20 km buffer areas around 31 North American Breeding Bird Survey transects, 12 located within the Edwards Plateau ecoregion and 18 in contiguous ecoregions. The number of bird species observed at each transect provided a measure of avian species richness associated with land cover classes for each respective transect (González in Urban influence on diversity of avifauna in the Edwards Plateau of Texas: effect of property sizes on rural landscape structure, Texas A&M University, 2005). Spatial correlations were calculated between each pair of the landscape indices. Spatial analysis identified a “threshold of habitat fragmentation” for the 500 acre (ac) ownership property size. Significant spatial correlations among variables showed that property sizes lower than 500 ac produced habitat fragmentation represented by a decrease in mean patch size (MN) and proximity among habitat patches (Index PROX). Spatial analysis also made possible the prioritization of ecological sub-regions of the Edwards Plateau for conservation or restoration. The Live Oak-Mesquite Savannah showed the highest average ownership property size (7305 ac) and the highest values of patch richness. Based on the results, management in the Live Oak-Mesquite Savannah sub-region should focus on the conservation of land mosaic diversity to assure native avian species turnover (Whittaker 1972). In Balcones Canyon Lands, 64 % of land was covered by farms smaller than 500 ac and the overall average ownership property size was above the threshold of fragmentation (1440 ac), implying that management policies there should focus both on habitat conservation and on restoration. In contrast, 71 % of land in the Lampasas Cut Plains was covered by farms smaller than 500 ac, and average ownership property size was very close to the fragmentation threshold (625 ac). Consequently, the results indicate that management in the Lampasas Cut Plains sub-region should focus on habitat restoration (e.g., corridors that connect isolated habitat patches). In general, the threshold of ownership property size, 500 ac, is important for conservation planning because below that threshold of property size, habitat patch size begins to decrease and the distance between equivalent patches of habitat increases. Isolated patches act as islands within a sea of less suitable habitat which produce negative effects on biodiversity. Identifying the spatial characteristics indicative of habitat fragmentation, or the likelihood thereof, is an important issue for conservation planning in places with urban sprawl influence.

Abolition Then and Now: Tactical Comparisons Between the Human Rights Movement and the Modern Nonhuman Animal Rights Movement in the United States

This article discusses critical comparisons between the human and nonhuman abolitionist movements in the United States. The modern nonhuman abolitionist movement is, in some ways, an extension of the anti-slavery movement of the eighteenth and nineteenth centuries and the ongoing human Civil Rights movement. As such, there is considerable overlap between the two movements, specifically in the need to simultaneously address property status and oppressive ideology. Despite intentional appropriation of terminology and numerous similarities in mobilization efforts, there has been disappointingly little academic discussion on this relationship. There are significant contentions regarding mobilization and goal attainment in the human abolitionist movement that speak to modern collective action on behalf of other animals. This article will explore the human abolitionist movement and discuss possible applications of movement organization, tactical repertoires, and goal attainment to the current nonhuman animal rights movement. Specifically, the utility of violence and legislative activism in the antislavery movement are discussed as potentially problematic approaches to abolishing nonhuman animal exploitation. Alternatively, the nonhuman animal rights focus on consumer resistance and nonviolence represent an important divergence in abolitionist mobilization.     

From Food Justice to a Tool of the Status Quo: Three Sub-movements Within Local Food

The local food movement has been touted by some as a profoundly effective way to make our food system become more healthy, just, and sustainable. Others have criticized the movement as being less a challenge to the status quo and more an easily co-opted support offering just another set of choices for affluent consumers. In this paper, we analyze three distinct sub-movements within the local food movement, the individual-focused sub-movement, the systems-focused sub-movement, and the community-focused sub-movement. These movements can be combined within any particular campaign or within the goals of any particular organization or individual activist, but they are nevertheless quite different from each other, and come out of different conceptualizations of what food, people, and locality are. We argue that most of the critiques leveled against local food are actually directed against the individual-focused sub-movement, which is most compatible with the current industrial food system, and perhaps not surprisingly receives the most mainstream attention. Further, we argue that while each movement has its own strengths and weaknesses, it is the community-focused sub-movement that has the most potential to radically transform the global food system.     

A Speaking Piglet Advertises Beef: An Ethical Analysis on Objectification and Anthropomorphism

The portrayal of animals in the media is often criticised for instrumentalising, objectifying and anthropomorphising animals (e.g. Hirschman and Sanders in Semiotica 115(1/2):53–79, 1997; Lerner and Kalof in Sociol Q 40(4):565–586, 1999; Stewart and Cole in Int J Multidiscip Res 12(4):457–476, 2009). Although we agree with this criticism, we also identify the need for a more substantiated approach to the moral significance of instrumentalisation, objectification and anthropomorphism. Thus, we propose a new framework which is able to address the morally relevant aspects of animal portrayal in the media. We closely examine the normative messages communicated by an unusual TV commercial in which an anthropomorphised piglet advertises organic beef. This serves as a case example to relate the philosophical and ethical concepts of objectification and anthropomorphism to each other and show how they can be applied. We conclude that the commercial conveys a message of animal instrumentalisation as being normatively correct within the constraint of good animal welfare. The depicted form of instrumentalisation is, nonetheless, associated with harm for the animals and thus, needs to overcome cognitive dissonance. To achieve this, animals are directly objectified by a trivialised and de-individualised portrayal. Moreover, animals are indirectly objectified even when they are anthropomorphised as they are granted significance only through being human-like. Thus, objectification and anthropomorphism are not opposing terms in our proposed framework. In addition, objectification, together with the reference to the dominant ideology, and combined with humorous anthropomorphism weakens scrutiny of these normative messages by the viewers. This eventually augments a decrease of moral concern for farmed animals in advertisement employing such portrayals.     

A 21st-Century perspective on snow drought in the Upper Colorado River Basin

In the Upper Colorado River Basin (UCRB), there is a deep reliance on seasonal snowpack for maintenance of water resources. The term “snow drought” has recently emerged to describe periods of anomalously low snowpack. Unique seasonal patterns in precipitation and temperature that drive snow drought can have distinct hydrologic signatures, and these relationships have not been carefully studied in the UCRB. Here we examine snow drought with a new classification scheme using peak snow water equivalent (SWE) and the ratio of basin-wide modeled peak SWE to accumulated (onset to peak) precipitation (SWE/P) that clusters snow drought years into three distinct groups—“warm,” “dry,” and “warm & dry”—that minimize within-group variance. Over the period 1916–2018, we identify 14 warm years ($\overline{P}$ = 160 mm; $\overline{\mathrm{SWE}/P}$ = 0.24), 24 dry years ($\overline{P}$ = 117 mm; $\overline{\mathrm{SWE}/P}$ = 0.35), and 21 warm & dry years ($\overline{P}$ = 94 mm; $\overline{\mathrm{SWE}/P}$ = 0.23). An elevation-based analysis reveals two distinct patterns: warm snow droughts see severe SWE reductions primarily at lower (<2600 m) elevations (65% at lower elevations, 37% overall), whereas “dry” scenarios exhibit a consistent reduction across all elevations (39% overall). Using naturalized streamflow data, we also differentiate snow droughts by their earlier streamflow timing and decreased peakedness (warm: 7 days, 2%; dry: 7 days, 2%; warm & dry: 13 days, 5%). This research provides new insights into snow drought patterns relevant for regional water management.     

Reversing food desertification: examining urban farming in Louisville,Chicago and Detroit

The Urban Farming Movement is relatively young in Louisville, Kentucky but it seems to be off to a good start. Being in its earliest stages, assessments of this effort must be made cautiously, even tentatively. Examining a movement that is in progress requires a study of the state's land use and segregation policies, both of which have been dynamic in Kentucky. Further, this study is also relevant as there is a growing convergence of national and regional attitudes towards American obesity, while there are competing notions of food preference and food choice. All of which are influenced by racial politics, and there is a deep concern regarding food security. Considering all of these, it is necessary to examine the Government's efforts to address obesity/food imbalance in a variety of settings, especially where urban farming is expanding, such as Chicago and Detroit. In New York, roof-top gardens dot the landscape and the urban farm movement is largely a “success”. So, city leaders have chosen to address another health issue – trans fat. Rather than joining the food choice/preference debate by banning fast-food restaurants, city leaders have chosen to enact a trans-fat ban. Unpopular at first, other cities and states have followed, and the Federal Government will mandate a trans-fat ban this year. In Louisville, Chicago and Detroit, where the trans-fat bans did not succeed, the urban farm movement may be the primary means of addressing malnutrition, in the form of obesity.     

<Emphasis Type="Italic">Laudato sì</Emphasis> and the New Paradigm of Catholic Environmental Ethics: Reflections on Environmentalist Movements in Italy

This article explores certain aspects related to the environmental ethical message in the Encyclical Letter Laudato si, written in 2015 by Pope Francis, leader of the Catholic Church, and compares them to recent Green party political movements in Italy. Italy offers a unique case study in that the religious background of the country acts as an independent variable with respect to the social acceptance of current environmental issues. The ethical message in Laudato sì is compared to recent debates on the moral responsibility of the individual and/or institution towards environmental problems; a range of responsibilities assumed by institutions versus individuals with regards to environmental problems are analyzed. In conclusion, parallels are made between the abovementioned ethical debate and the ethical contents of the Encyclical Letter.     

Novel dimensionless index for physically based assessment of thermal refugia characterizes off-channel habitat on gravel bed river

In the Willamette River, OR, main channel temperatures can be too warm for cold water fishes, causing fish to concentrate in secondary channel features that provide thermal refugia. However, temperature regimes vary among and within features. Improved understanding of physical processes controlling thermal regimes is needed. This study developed a dimensionless index for assessment of thermal refugia on the upper Willamette River. The novel hyporheic insolation (HIN) index uses minimal field measurements to predict thermal refugia resulting from buffering. Continuous water temperature measurements at one side channel, eight alcoves, and six beaver ponds provided data to ground truth calculated ${ℍ}_{\text{in}}$ predictions. Water temperature records were first used to characterize stratification at sites. Calculation of the Richardson number, an index of stability, showed two well-mixed sites and 13 stratified sites. At stratified sites, calculated ${ℍ}_{\text{in}}$ values characterized the ratio of cooling flux from hyporheic discharge to heat flux from incoming solar radiation. As ${ℍ}_{\text{in}}$ increased, measured temperatures at sites decreased. Despite overall scatter, a logarithmic fit to bin-averaged ${ℍ}_{\text{in}}$ values showed R² = 0.91. Calculations suggest that secondary channel features characterized by stratification and cool hyporheic discharge can provide thermal refugia. Accordingly, the HIN index may serve as a practical tool grounded in physical processes governing temperature across a floodplain.     

Optimizing Bankfull Discharge and Hydraulic Geometry Relations for Streams in New York State1

Mulvihill, Christiane I. and Barry P. Baldigo, 2012. Optimizing Bankfull Discharge and Hydraulic Geometry Relations for Streams in New York State. Journal of the American Water Resources Association (JAWRA) 48(3): 449-463. DOI: 10.1111/j.1752-1688.2011.00623.x Abstract: This study analyzes how various data stratification schemes can be used to optimize the accuracy and utility of regional hydraulic geometry (HG) models of bankfull discharge, width, depth, and cross-sectional area for streams in New York. Topographic surveys and discharge records from 281 cross sections at 82 gaging stations with drainage areas of 0.52-396 square miles were used to create log-log regressions of region-based relations between bankfull HG metrics and drainage area. The success with which regional models distinguished unique bankfull discharge and HG patterns was assessed by comparing each regional model to those for all other regions and a pooled statewide model. Gages were also stratified (grouped) by mean annual runoff (MAR), Rosgen stream type, and water-surface slope to test if these models were better predictors of HG to drainage area relations. Bankfull discharge models for Regions 4 and 7 were outside the 95% confidence interval bands of the statewide model, and bankfull width, depth, and cross-sectional area models for Region 3 differed significantly (p < 0.05) from those of other regions. This study found that statewide relations between drainage area and HG were strongest when data were stratified by hydrologic region, but that co-variable models could yield more accurate HG estimates in some local regional curve applications.
