Ethical Issues Related to Food Sector Evolution in Developing Countries: About Sustainability and Equity

After a century of major technicaladvance, essentially achieved by and for theindustrialized countries, the evolution of thefood sector in southern countries should nolonger be thought of in terms of a ``headlongpursuit.'' In the present context of demographicgrowth, urbanization, poverty and disparities,environmental degradation, and globalization oftrade, new priorities have emerged, and newethical questions have been raised, mainlyrelated to sustainability and equity. Thispaper analyses these ethical concerns in thefollowing terms: can the model of food sectordevelopment initiated by the industrializedcountries be applied to the entire world on asustainable and equitable basis, given theeffects of this development with regard to theenergy consumed, the changes in dietarybehavior and related nutritional problems, thenew demands in terms of food safety, thequestions of biodiversity, ownership ofknowledge, cultural identities, gender issues,and Man's relationship to food and Nature?     

Animal Agriculture: Symbiosis, Culture, or Ethical Conflict?

Several writers on animal ethics defend the abolition of most or all animal agriculture, which they consider an unethical exploitation of sentient non-human animals. However, animal agriculture can also be seen as a co-evolution over thousands of years, that has affected biology and behavior on the one hand, and quality of life of humans and domestic animals on the other. Furthermore, animals are important in sustainable agriculture. They can increase efficiency by their ability to transform materials unsuitable for human consumption and by grazing areas that would be difficult to harvest otherwise. Grazing of natural pastures is essential for the pastoral landscape, an important habitat for wild flora and fauna and much valued by humans for its aesthetic value. Thus it seems that the environment gains substantially when animals are included in sustainable agricultural systems. But what about the animals themselves? Objections against animal agriculture often refer to the disrespect for animals’ lives, integrity, and welfare in present intensive animal production systems. Of the three issues at stake, neither integrity nor animal welfare need in principle be violated in carefully designed animal husbandry systems. The main ethical conflict seems to lie in the killing of animals, which is inevitable if the system is to deliver animal products. In this paper, we present the benefits and costs to humans and animals of including animals in sustainable agriculture, and discuss how to address some of the ethical issues involved.

Barriers to Water Conservation in the Rio Grande Basin1

Abstract: The Rio Grande basin shares problems faced by many arid regions of the world: growing and competing demands for water and river flows and uses that are vulnerable to drought and climate change. In recent years legislation, administrative action, and other measures have emerged to encourage private investment in efficient agricultural water use. Nevertheless, several institutional barriers discourage irrigators from investing in water conservation measures. This article examines barriers to agricultural water conservation in the Rio Grande basin and identifies challenges and opportunities for promoting it. Several barriers to water conservation are identified: clouded titles, water transfer restrictions, illusory water savings, insecure rights to conserved water, shared carry‐over storage, interstate compacts, conservation attitudes, land tenure arrangements, and an uncertain duty of water. Based on data on water use and crop production costs, price is found to be a major factor influencing water conservation. A low water price discourages water conservation even if other institutions promote it. A high price of water encourages conservation even in the presence of other discouraging factors. In conclusion, water‐conserving policies can be more effectively implemented where water institutions and programs are designed to be compatible with water’s underlying economic scarcity.     

Stewardship of Natural Resources: Definition, Ethical and Practical Aspects

Stewardship is potentially a usefulconcept in modernizing management philosophies. Use ofthe term has increased markedly in recent years, yetthe term is used loosely and rarely defined in landmanagement literature. The connections between thispractical usage and the ethical basis of stewardshipare currently poorly developed. The followingdefinition is proposed: ``Stewardship is theresponsible use (including conservation) of naturalresources in a way that takes full and balancedaccount of the interests of society, futuregenerations, and other species, as well as of privateneeds, and accepts significant answerability tosociety.' A religious interpretation would require thephrase ``and ultimately to God' to be added.Stewardship has both secular and religiousinterpretations and it will be desirable to developboth of these aspects in parallel. A task forphilosophers is to establish whether the ethical basisof stewardship is sufficient to address environmentalconcerns or whether it is necessary to embrace widerethical approaches. Stewardship occupies similarground to several other concepts of use and managementof resources, particularly sustainability. It canbuild on sustainability by encouraging a broader viewof who and what should benefit from managementactivity. In particular, it focuses attention on therole of managers in providing public benefit and onenvisaging other species as a form of ``stakeholder' inmanagement decisions. Stewardship is applicable acrossthe widest range of fields of resource use and alsohas relevance to aspects of land tenure and propertyrights. Application of stewardship will require someadjustments in the roles of private managers/ownersvis-à-vis government. It might providemanagers with an expanded role and, importantly, amore positive image, both of themselves and in theeyes of the public. Stewardship could alsobe developed in a way that has relevance to citizensin general (as opposed to managers and owners ofresources), through their interactions with naturalresources as consumers.     

Opening Up for Participation in Agro-Biodiversity Conservation: The Expert-Lay Interplay in a Brazilian Social Movement

In science and environmental studies, there is a general concern for the democratization of the expert-lay interplay. However, the democratization of expertise does not necessarily lead to more sustainable decisions. If citizens do not take the sustainable choice, what should experts and decision makers do? Should the expert-lay interplay be dissolved? In thinking about how to shape the expert-lay interplay in a better way in agro-biodiversity conservation, I take the case of the MST (Movimento Sem Terra/Landless People’s Movement), possibly the largest rural movement in Latin America. The MST is in a process of turning towards environmentalism. It has adopted agroecology, a democratically oriented knowledge field. However, not all of the farmers were willing to adopt new environmentalist ideas and practices. Through ethnographic research, I analyze how expertise was recognized and redistributed within the MST, attending particularly to the role of MST coordinators and technicians. I explore how participation was framed and put into action. The adoption of agroecology brought to the MST a new and more inclusive map of expertise, but it also influenced new social distinctions within the communities. In part, farmers’ knowledge was labeled as ignorance. This may close down possibilities for dialogue as well as for sustainability. The paper suggests that experts’ power for discriminating among lay knowledges should come together with a responsibility for opening spaces for dialogue and action. One way of doing so could be by adding “interactional reflexivity” to experts’ expertise.

The Fat of the Land: Linking American Food Overconsumption, Obesity, and Biodiversity Loss

Americans’ excessive consumption of food harms their health and quality of life and also causes direct and indirect environmental degradation, through habitat loss and increased pollution from agricultural fertilizers and pesticides. We show here that reducing food consumption (and eating less meat) could improve Americans’ health and well-being while facilitating environmental benefits ranging from establishing new national parks and protected areas to allowing more earth-friendly farming and ranching techniques. We conclude by considering various public policy initiatives to lower per capita caloric intake and excessive meat consumption, and to translate this temperate behavior into substantial environmental protection.     

Biodiversity Conservation in the Thar Desert; with Emphasis on Endemic and Medicinal Plants

The Indian desert, the Thar Desert, has its own importance and specific characteristics with respect to endemic and medicinal plants. Forty-five plant species are considered to be rare and/or endangered. The desert has a large number of plants of economic importance and medicinal use. The Thar Desert is thickly populated in comparison to other hot deserts of the world. 17.44 million people and 23.33 million livestock are recorded from the region. These populations exert pressure on the biological resources of the Thar Desert causing a lack of sustainability and necessitate conservation of biodiversity actions.     

On Finding Solutions to Ethical Problems in Agriculture

A distinction should be made betweentwo types of ethical problems. A Type I ethicalproblem is one in which there is no consensusas to what is ethical. A Type II ethicalproblem is one in which there is a consensus asto what is ethical, but incentives exist forindividuals to behave unethically. Type Iethical problems are resolved by making,challenging, and reasoning through moralarguments. Type II ethical problems areresolved by changing the institutionalenvironment so that people do not haveincentives to behave unethically. Type Isolutions, however, will not be effective insolving Type II problems. Examples inagriculture and elsewhere show howdistinguishing between Type I and Type IIethical problems will help in theidentification of solutions to ethical issuesin agriculture.     

From Environmental Ethics to Nature Conservation Policy: Natura 2000 and the Burden of Proof

Natura 2000 is a network of natural sites whose aim is to preserve species and habitats of relevance in the European Union. The policy underlying Natura 2000 has faced widespread opposition from land users and received extensive support from environmentalists. This paper addresses the ethical framework for Natura 2000 and the probable moral assumptions of its main stakeholders. Arguments for and against Natura 2000 were analyzed and classified according to “strong” or “weak” versions of the three main theories of environmental ethics – anthropocentrism, biocentrism, and ecocentrism. Weak (intergenerational) anthropocentrism was found to underlie the Natura 2000 network itself and the positions of environmentalists, while strong (traditional) anthropocentrism pervaded the positions of economic developers. Land users seemed to fall somewhere between weak and strong anthropocentrism. The paper discusses the relation between ethics and different attitudes towards Natura 2000, highlighting some of the implications for the network’s ongoing implementation. It is shown that Natura 2000 achieves a strong reversal of the burden of proof from conservation to economic development and land use change under anthropocentrism. It is argued that the alleged theoretical divide between anthropocentrism and non-anthropocentrism in relation to the burden of proof does not seem to hold in practice. Finally, it is predicted that the weak versions of anthropocentrism, biocentrism, and ecocentrism, are likely to converge extensively in respect to nature conservation policy measures.“Charting the depths of law and policy disputes yield an understanding of ethical differences.” Paul B. Thompson (2002, p. 189).     

The Use of Species-decline Statistics to Help Target Conservation Policy for Set-aside Arable Land

The set-aside scheme of the E.C. is a way of dealing with the socio-economic problem of food surpluses, but it also presents opportunities for environmental benefits. To help target set-aside policies, three groups of species (scarce plants, butterflies and grasshoppers) were analysed by present and past distribution and by habitat. In those biotopes which could be restored using set-aside land, chalk grassland has shown the greatest decline of scarce plants, and the two insect groups have declined the most in heathland, water-fringe vegetation and woodland edges. However, declines were also observed for other biotopes. These and other data suggest that conservation efforts on a set-aside land should not be concentrated on a particular kind of habitat, but should address a diversity of habitats in a diversity of locations. This conclusions has been used to help defined the 1993 set-aside schemes for the U.K.     

Water Mass Balances for the Solaire and the 2020 Tower: Implications for Closing the Water Loop in High‐Rise Buildings1

Abstract: Building water mass balances were performed for one 150‐story conventional building scenario for comparison with three scenarios of the 2020 Tower, a hypothetical 150‐story high‐rise building with on‐site wastewater treatment and reuse. To ensure that the assumptions for the hypothetical building are appropriate, a one‐year water balance was also conducted of the existing 27‐story Solaire building that partly closes the water/wastewater loop, meters major water flows and implements low‐flow/water conserving fixtures and appliances. For comparison, a conventional 27‐story building scenario with the same low‐flow/water conserving fixtures as the Solaire but no water reuse was also assessed. The mean daily indoor water use in the Solaire was 246 l/(d cap) which exceeds mean daily water use found in the literature. The water mass balances showed that an urban high‐rise building needs another source of water even when potable reuse water is produced because of losses during water end use and treatment (i.e., evaporation, water in treatment residues). Therefore, water conservation (i.e., modification of human behavior) and water efficiency improvements (i.e., equipment, appliances and fixtures) are important major factors in reducing the municipal water needed in all scenarios.     

Naturalness and Conservation in France

This article discusses the ecological and cultural criteria underlying the management practices for protected areas in France. It examines the evolution of French conservation from its roots in the 19th century, when it focused on the protection of scenic landscapes, to current times when the focus is on the protection of biodiversity. However, biodiversity is often socially defined and may not represent an ecologically sound objective for conservation. In particular, we question the current approach to protecting a specific type of biodiversity that is at the basis of traditional landscape but does not value systems that are left to develop naturally (i.e., without significant human intervention). We present several examples of current attempts in France and Europe to managing traditional ecosystems and then discuss the values that exist in systems that develop naturally. We feel the latter systems often have much to offer in terms of biodiversity as well as providing important sites for the study of dynamic ecological communities in an ever-changing world.     

Protecting the National Estate: Issues and practice in Australian Heritage Conservation

Summary The author presents a personal view of the role and functions of both the Australian Heritage Commission and the Australian Register of the National Estate. Operational problems are highlighted, and a critique of the Commission and difficulties encountered in working within both national and federal political confines, are outlined. In a decade, the Commission has achieved much towards the preservation of the Australian environment: important in the Commission's current activity is the task of explaining to the lay public precisely what heritage conservation entails and why it is an essential activity.Professor Bruce Davis has been, in the past, Chairman of the Australian Heritage Commission and the contents of this paper are based upon his delivery of an address at the inaugural conference of the Environment Institute of Australia, in Sydney, during November 1987. The views expressed are the personal opinion of the author and should not be construed as necessarily representing the policy of views of any institution with which the author may be connected.
