Is Abolitionism Guilty of Racism? A Reply to Cordeiro-Rodrigues

Gary Francione is an abolitionist: he maintains that we ought to abolish the institutions and practices that support the exploitation of animals. He also believes that veganism is the “moral baseline”—that is, he thinks it’s morally required of nearly everyone in the developed world, and many beyond it. Luis Cordeiro-Rodrigues claims that abolitionism is guilty of racism, albeit “racism without racists.” I contend that his arguments for this conclusion aren’t successful.     

Lead uptake by Eichhornia Crassipes

Factors influencing uptake of lead(II) by the water hyacinth (Eichhornia Crassipes), were examined. Two phases of uptake were observed for the concentration range investigated (0.01–1000 ppm). The initial, rapid uptake phase of about 4 hours is followed by a slower, near linear phase extending past 24 hours. Stirring the solution enhanced uptake, suggesting that lead removal is in part diffusion limited. In the range of 4–8, pH has little effect on uptake where as outside this range, uptake is reduced. Increased solution volume or rootmass results in more metal being removed by the plant. The presence of strong complexers blocks the initial rapid uptake phase as does the presence of Zn(II), Cd(II), Hg(II), and Fe(III). Strong complexers can also strip a portion of any lead already removed from solution by the plant.     

Characterizing vulnerability to water scarcity: The case of a groundwater-dependent,rapidly urbanizing region

Groundwater overdraft is a resource management issue that poses a threat for the security of communities. Impacts of groundwater overdraft are influenced by the biophysical and social contexts of water management. This paper presents a method for assessing vulnerability to water scarcity in spatial terms using biophysical and social indicators. A geographic information system was used to establish areas of vulnerability based upon hydrologic variability in water resource availability within a groundwater basin, three types of water management systems, and 10 sociodemographic characteristics. Our study area is in the rapidly urbanizing Arizona Central Highlands, located ~150km north of the Phoenix metropolitan region, USA. Results indicate that the most biophysically vulnerable places do not necessarily intersect with the most vulnerable populations and that local differences in vulnerability are interrelated, rather than independent, outcomes in a process of socioenvironmental transformation. Vulnerability is influenced by laws that deny access to local surface waters and lead to dependence on fossil groundwater, and by economic reliance on urbanization. Localities attempt to reduce vulnerability through the development of community water systems and the expansion of water frontiers. While such strategies may reduce local vulnerability, they are not sustainable solutions because they transfer risks to other places, and thus contribute to vulnerability elsewhere.     

Sustainable recycling model: A comparative analysis between India and Tanzania

Higher economic growth in developing countries has caused higher amounts of wastes. Local government authorities in these countries usually fail to provide adequate services to dispose the increasing amounts of waste, resulting in threats for both the population and environment health. There is therefore an urgent need for recycling as a form of waste management in order to stop the devastating effects of solid waste in developing countries. Using a qualitative method of analysis, this study presents a model to measure and rank the sustainability of recycling programs in India and Tanzania. The model consists of six main constructs including “production, economic, governmental, social, technological, and international factors”. The results showed that India outperforms Tanzania in sustainable recycling programs: per capita waste generated per day in Delhi is higher than in Dar es Salaam; the government of India focuses more on developing recycling plans and techniques as compared to the government of Tanzania where the country is not actively involved in the recycling process; and the solid waste management planning in India is being performed better than Tanzania.

The role of collaboration in environmental management: an evaluation of land and resource planning in British Columbia

Recent literature on land-use planning proposes the use of innovative collaborative planning (CP) models to resolve planning disputes. This paper uses a participant survey based on 25 evaluative criteria to evaluate an application of CP to land-use planning in British Columbia, Canada. The results show that CP is an effective means of resolving environmental conflict and produces significant additional benefits such as improved stakeholder relations, skills, and knowledge. The case study evaluation also identifies the keys to successful CP management including factors related to process design and external circumstances.     

Agricultural Abandonment in the North Eastern Iberian Peninsula: The Use of Basic Landscape Metrics to Support Planning

Land abandonment is an important cause of changes in landscape patterns in the Mediterranean area. There is a need to monitor land use and land cover changes in order to provide quantitative evidence of the relationship between land abandonment and the formation of new landscape patterns. Appropriate management policies to encourage sustainable development can then be developed. This paper describes how to monitor landscape dynamics using different temporal land use and land cover data generated from field survey and airborne information. The results showed that the abandonment of agricultural land generally results in an increase of vegetation biomass. This process leads to homogenization of the landscape. In addition, abandonment promotes fragmentation of agricultural land. Based on these results, the paper discusses the implications for rural management policies concerning the abandonment of agricultural land and suggests recommendations for the development of such policies.
