Using a Systematic Approach to Select Flagship Species for Bird Conservation

Conservation marketing campaigns that focus on flagship species play a vital role in biological diversity conservation because they raise funds and change people's behavior. However, most flagship species are selected without considering the target audience of the campaign, which can hamper the campaign's effectiveness. To address this problem, we used a systematic and stakeholder‐driven approach to select flagship species for a conservation campaign in the Serra do Urubu in northeastern Brazil. We based our techniques on environmental economic and marketing methods. We used choice experiments to examine the species attributes that drive preference and latent‐class models to segment respondents into groups by preferences and socioeconomic characteristics. We used respondent preferences and information on bird species inhabiting the Serra do Urubu to calculate a flagship species suitability score. We also asked respondents to indicate their favorite species from a set list to enable comparison between methods. The species’ traits that drove audience preference were geographic distribution, population size, visibility, attractiveness, and survival in captivity. However, the importance of these factors differed among groups and groups differed in their views on whether species with small populations and the ability to survive in captivity should be prioritized. The popularity rankings of species differed between approaches, a result that was probably related to the different ways in which the 2 methods measured preference. Our new approach is a transparent and evidence‐based method that can be used to refine the way stakeholders are engaged in the design of conservation marketing campaigns.     

WSSD 2002, Latin America and Brazil: Biodiversity and Indigenous People

Latin America comprehends notable variations in terms of natural environment, availability of natural resources, living standards, and demographic patterns. Latin America is a mosaic of cultures, post- and pre-Columbian. The rich variety of life forms discovered and described by chroniclers and traveling naturalists in the Neotropics contributed to the proposal, in mid-XVIIIth century, of a new system of classification and a scientific code of nomenclature for all organisms. Biodiversity was, for many centuries, a source of resources to be exploited in natura. In scientific circles, its inventory became the domain of taxonomists. But modern technology showed how important the miriad of life forms really are as sources of chemical molecules to be engineered as drugs and reassembled as novel manufactured products. We are on the brink of a new agricultural and medical revolution, thanks to the techniques of genetic engineering, which will lead eventually to the elimination of hunger and malnutrition.In this essay, the Brazilian environmental and social heterogeneity will serve as an example to illustrate some key points, which have influenced sustainability policies. The Amazon deforestation and indigenous knowledge (IK), subjects often associated with areas of high biodiversity, are usually the focus of environmental debates. The importance of IK in integrating development, reducing poverty and sustainability are considered together with the intellectual property rights of native populations.In the World Summit on Sustainable Development (WSSD) Implementation Plan, a few paragraphs were dedicated to Latin America, because of the pre-existing Action Platform on the Road to Johannesburg 2002, approved in Rio de Janeiro in October 2001. This paper calls attention to the need to draw up specific environmental policies for a region which shows an extremely high cultural and biological diversity, associated with a high availability of forests and water, among other resources.     

Improving Access to Water Resources through Rainwater Harvesting as A Mitigation Measure: The Case of the Brazilian Semi-Arid Region

This paper focuses on the importance of rainwater harvesting to mitigate the scarcity of water in the semi-arid region of Brazil. It is a case study about the Million Cisterns Project, an initiative developed by NGOs with the support of Brazilian Federal Government Institutions and international funding organizations. The project is innovative in a series of ways when compared to mitigation measures previously implemented by the government. Instead of focussing on short-term, top-down, palliative measures based on the construction of dams and wells, it focuses on low cost, bottom-up, long-term measures and, most importantly, it involves an educational component. Thus, the provision of water is closely related to the empowerment of the most destitute population and this leads to the sustainability of the actions. The case study serves to illustrate the relevance of the partnership between grassroots organizations and governmental institutions in the context of mitigation.     

Anthropogenic influence on the water quality in Guanabara Bay, Rio de Janeiro, Brazil

Guanabara Bay is a 384-km² coastal bay with 70% of the population of the metropolitan area of Rio de Janeiro located within its drainage basin. The water quality of the Bay is impacted by domestic and industrial runoff, of which only 15% has been adequately treated. However, based on a 14-year monitoring program, the water quality for most of Guanabara Bay remains acceptable because of intense tidal flushing, and we failed to find a worsening of conditions during the 14-year study. The inner shallow regions of the Bay, the western and northwestern parts, receive most of the drainage from metropolitan Rio de Janeiro. It is here that the water quality is alarmingly poor, characterized by hypertrophic conditions and occasional hypoxic events. Fecal coliform counts in these inner reaches of the Bay are 4–100 times higher than the maximum acceptable count for recreational waters. Hypertrophic conditions prevail in Guanabara Bay, which is characterized by low dissolved oxygen, high biochemical oxygen demand, peaks in fecal coliform, and extremely high chlorophyll-a concentrations, which reflect high quantities of nutrients entering the system. These anthropogenic pressures are a threat to planktonic and benthic communities and are reminiscent of San Francisco Bay 30 years ago. The Guanabara Bay water quality could be returned to pre-1950 conditions, but it would require sufficient political will and economic investment to ensure that at least 80–90% of the domestic and industrial sewage were treated adequately.

Unexplored Diversity and Conservation Potential of Neotropical Hot Caves

The term hot cave is used to describe some subterranean chambers in the Neotropics that are characterized by constantly high ambient temperatures generated by the body heat of high densities of certain bat species. Many of these species have limited geographic ranges, and some occur only in the hot‐cave environment. In addition to the bats, the stable microclimate and abundant bat guano provides refuge and food for a high diversity of invertebrates. Hot caves have so far been described in the Caribbean and in a few isolated locations from Mexico to Brazil, although there is some evidence that similar caves may be present throughout the tropics. The existing literature suggests these poorly known ecosystems, with their unique combination of geomorphology and bat‐generated microclimate, are particularly sensitive to disturbance and face multiple threats from urbanization, agricultural development, mining, and tourism.

Extracted and farmed shrimp fisheries in Brazil: economic, environmental and social consequences of exploitation

This paper analyses shrimp caught from the wild and farmed shrimp in Brazil, focusing on production, amounts exported and earnings, with comparisons drawn to all of South America and the world in general. We show that wild caught shrimp still comprises the majority of what is produced and exported in Brazil, although aquaculture has been taking a relevant role in the internal and external scenario, reaching similar levels of extraction in recent years. Despite some fluctuations in the amount of extracted shrimp, Brazil increased its production from 15,000 tons in 1950 to 80,000 in 2004. The money earned with shrimp product exportation, which includes farmed shrimp as well, followed a similar tendency. Shrimp aquaculture began late in Brazil, in 1974, and grew slowly until 1995, initiating an accelerated growing process; current estimates assume 50,000 people are employed in this activity, producing about 76,000 tons of shrimp every year. Although still incipient in relation to the world shrimp farmed production, Brazil has been assuming a relevant role in South America, yielding 44% of its total production, in 2004. Despite the importance of shrimp to the country, no studies have been conducted to explore the interrelations between the environmental and social consequences of such unplanned aquaculture growth or uncontrolled wild shrimp fishing. Based on previous observations, conflicts exist between different fishing scales. However, the consequences of shrimp farming on society (displacement from their lands, changes in the life quality, etc.) have not yet been explored. Both activities, shrimp exploitation and aquaculture, deserve better control and structure toward sustainable shrimp fishing and farming.

Government and voluntary policymaking for sustainability in mining towns: A longitudinal analysis of Itabira,Brazil

The socio‐economic fabric of single‐company mining towns needs to be carefully considered by both Government and companies in sustainability policymaking. Policy design and effectiveness in such towns are significantly impacted by the city's economic dependence on a single company. This paper explores the perceived effectiveness of government and voluntary private sector mining policies for pursuing sustainability in the historic mining town of Itabira, Brazil over a period of 20 years. Itabira serves as a worthwhile case study because it allows for an in‐depth and longitudinal analysis that can reveal valuable lessons to policymakers of different sectors and jurisdictions located elsewhere. Based on extensive face‐to‐face interviews and literature reviews, study results indicate that changes to the state environmental licensing policies in the 1990s led to significant socio‐environmental improvements in the area. The globalization of the mining company also contributed to an increase in the quantity and quality of voluntary industry policies. Recent technological improvements in the beneficiation processes of the mining company promises to extend the life of the mine to 2050. Although there are significant incremental socio‐environmental policies and programmes, sustainability remains an elusive vision in Itabira, with no clear objectives or monitoring and accountability mechanisms. The paper concludes by recommending a more formal integrated policymaking framework.     

Framing frontier governance through territorial processes in the Brazilian Amazon

The policy intervention to enforce property rights and control deforestation frontiers is often undermined in the Brazilian Amazon, and this intervention problem is considered to be stemming from weak frontier governance. However, little has been understood how this governance can be strengthened in the context of social change. Drawing on a literature review of the Amazon development and sociological studies of space, this article argues that frontier governance is characterised by the co-generation of two territorial processes: the official settlement implementation (physical spacing) and the spontaneous settlers' shaping of the vernacular community (production of place). The co-generation process opens new deliberative space where both state and non-state actors claim authority over the intervention. Therefore, strengthening frontier governance involves empowering this emerging authority to be able to promote public engagement with sustainable development on the frontier. The article uses the regional history and ethnographic material collected in the southeast of Pará to illustrate the discussion.     

Environmental Impacts of Brazil's Tucuruí Dam: Unlearned Lessons for Hydroelectric Development in Amazonia

Brazil's Tucuruí Dam provides valuable lessons for improving decision-making on major public works in Amazonia and elsewhere. Together with social impacts, which were reviewed in a companion paper, the project's environmental costs are substantial. Monetary costs include costs of construction and maintenance and opportunity costs of natural resources (such as timber) and of the money invested by the Brazilian government. Environmental costs include forest loss, leading to both loss of natural ecosystems and to greenhouse gas emissions. Aquatic ecosystems are heavily affected by the blockage of fish migration and by creation of anoxic environments. Decay of vegetation left in the reservoir creates anoxic water that can corrode turbines, as well as producing methane and providing conditions for methylation of mercury. Defoliants were considered for removing forest in the submergence area but plans were aborted amid a public controversy. Another controversy surrounded impacts of defoliants used to prevent regrowth along the transmission line. Mitigation measures included archaeological and faunal salvage and creation of a “gene bank” on an island in the reservoir. Decision-making in the case of Tucuruí was virtually uninfluenced by environmental studies, which were done concurrently with construction. The dam predates Brazil's 1986 requirement of an Environmental Impact Assessment. Despite limitations, research results provide valuable information for future dams. Extensive public-relations use of the research effort and of mitigation measures such as faunal salvage were evident. Decision-making was closely linked to the influence of construction firms, the military, and foreign financial interests in both the construction project and the use of the resulting electrical power (most of which is used for aluminum smelting). Social and environmental costs received virtually no consideration when decisions were made, an outcome facilitated by a curtain of secrecy surrounding many aspects of the project. Despite improvements in Brazil's system of environmental impact assessment since the Tucuruí reservoir was filled in 1984, many essential features of the decision-making system remain unchanged.     

Prospects for the co‐management of mangrove ecosystems on the North Brazilian coast: Whose rights,whose duties and whose priorities?

This article describes the co‐management approach in situations of open access to and of increasing pressure on resources, using a mangrove coastal zone in North Brazil as an example. Co‐management clearly has the potential to turn nonviable, de facto open access to mangroves into effective common property management. Alliances of different political and ideological groups have been formed under the RESEX (reservas extrativistas — natural resource user reserve) model of coastal co‐management. Local economic interests have been mobilized as client constituencies. The RESEX system of co‐management assigns additional duties to both co‐managing parties, i.e., the state administration and the local users, in exchange for new rights. The authors argue that local support for the RESEX model has been gained on partially distorted premises. As the public authority passes on responsibility for management to local users under the RESEX model, this entails a number of duties for the local users. Thus local users assume the duty to implement and monitor resource management; they also appear to gain the right to take local decisions, such as excluding outsiders from resource access, and designing local resource management rules. However, as this article shows with two examples, some important new rights for local users under the RESEX co‐management concept are contrary to environmental legislation in force. This conflict is at present unresolved. It is argued that increased transparency about their precise rights for local resource co‐managers will considerably improve the prospects of coastal co‐management in Brazil.
