The research methods include key informant interview, group discussio...     

Indigenous knowledge on use values of Karvan district plants,Iran

Traditional and indigenous knowledge on plants usage is a valuable source of information from cultural and natural perspectives, reflecting society’s complicated and close relationship with the environment. Communities have a valuable source of traditional knowledge on the utilization of natural resources, and it is worth to be documented and preserved for current and future applications. We conducted this research to collect and identify plant species of Karvan District and document the traditional knowledge on their use and consumption values. Regarding the results, 150 plant species are used by local communities, more than 30 % of which are directly consumed as food, 24 % (37 species) are used as medicinal plants, and 16.3 % are applied for decoration purposes; 58.6 % of the species are consumed in the raw form, and the remaining is processed before consumption. Leaves (35 %), seeds (21 %) and flowers (21 %) are the most frequent parts of the plants that are used. High number of young emigrants to industrialized areas in seek of job opportunities is threatening this precious source of indigenous knowledge. Attempts to preserve this empirical source of information by encouraging trans-generational knowledge transmission would help to maintain it for future applications.     

Practising the past in the present: using Ghanaian indigenous methods for water quality determination in the contemporary era

Surface water sources remain the dominant sources of water supply for a significant proportion of poor communities. These water supply sources tend to have low water quality levels. Application of water quality determination and purification measures could minimize water-related diseases associated with direct consumption of water with poor quality levels. A number of simple measures have been devised and utilized by indigenous communities based on their resource conservation knowledge to improve water quality levels. However, scientific approaches that are more in tune with modern demands for reliability and exactness are the preferred, mainstream approaches for determining water quality. Growing recognition of the relevance of indigenous knowledge has led to renewed interest in the possibility of utilizing it for such tasks. Research conducted in 2007 and 2008 in two indigenous communities in Ghana revealed a diversity of indigenous methods for water quality determination and purification including straining, settling and use of special seeds which could still be useful in this contemporary era. This paper recommends that knowledge co-production and transdisciplinary approaches be employed to enable indigenous communities and experts to collaborate and develop measures that tap both knowledge systems for improving water quality levels for human use.     

Anishnaabe Aki: an indigenous perspective on the global threat of invasive species

Conservation discourses tend to portray invasive species as biological entities temporally connected to colonial timelines, using terms such as “alien”, “colonizing”, “colonial”, and “native”. This focus on a colonial timeline emerges from scientific publications within conservation biology and invasion ecology and is enacted through invasive species management by state and NGO actors. Colonialism is influential for indigenous nations in myriad ways, but in what ways do indigenous understandings of invasive species engage with colonialism? We conducted ethnographic research with indigenous Anishnaabe communities to learn about the ways Anishnaabe people conceptualize invasive species as a phenomenon in the world and were gifted with three primary insights. First, Anishnaabe regard plants, like all beings, as persons that assemble into nations more so than “species”. The arrival of new plant nations is viewed by some Anishnaabe as a natural form of migration. The second insight highlights the importance of actively discovering the purpose of new species, sometimes with the assistance of animal teachers. Lastly, while Anishnaabe describe invasive species as phenomenologically entangled with colonialism, the multiple ways Anishnaabe people think about invasive species provide alternatives to native–non-native binaries that dominate much of the scientific discourse.     

Policy diffusion in arid Basin water management: a Q method approach in the Murray–Darling Basin,Australia

The Murray–Darling Basin is Australia’s national food bowl, home to almost half of the national income from food production, as well as internationally significant wetlands, iconic red gum forests, endangered flora and fauna, and approximately 40 autonomous indigenous nations. Persistent severe drought and extreme flooding episodes have presented new challenges in the region. Chief among these challenges is the establishment of a legitimate framework to sustainably manage water resources that finds common ground between environmental, indigenous and commercial interests. A powerful approach to examine these processes is through the theory of diffusion and adaptation of policy innovations. Here, we describe an approach to place this theory on empirical ground using Q methodology. We elucidate patterns of subjectivity, to explore the perceptions of expert advice, subsidiarity and local knowledge to better understand the interests in play. We find that respect is held for local practitioners (water managers and farmers) and indigenous knowledge, but while policy innovations are being generated, the diffusion of policy is contested. We identify the potential, though limited, for common ground through substantive and respectful consultation.     

Exploring Indigenous Understandings of River Dynamics and River Flows: A Case from New Zealand

Indigenous communities are particularly sensitive to the use and development of freshwaters, as they hold distinct perspectives on water which reflect their identity, and their custodial obligations to manage tribal waters. Within New Zealand, Maori (the indigenous people) have, for generations, voiced their concerns about the continual modification of waterways within their tribal territories. Until about the mid-nineteenth century, water quality was at the forefront of issues concerning human manipulation of rivers and streams. A range of new issues then arose that were increasingly concerned with reduced river flows. Of the many techniques developed to address these issues, many rely heavily on professional expertise and objective, scientific philosophies, which often fail to recognize cultural values, and benefit from cultural knowledge. This essay presents examples of the knowledge of streams and rivers held within Maori communities that could benefit contemporary resource management if it can be determined how cultural knowledge and practices and scientific approaches can be communicated and integrated.     

Do protected areas really work to conserve species? A case study of three vulnerable woody species in the Sudanian zone of Burkina Faso

Natural vegetation and native plant species contribute significantly to the daily needs of local people especially in developing countries. This exerts a high pressure on local species and jeopardizes the conservation of the most vulnerable plants. In Burkina Faso, conservation measures, such as the creation of protected forests, have been taken to safeguard the remaining indigenous vegetation. However, little is known about the effectiveness of these protected areas in conserving biodiversity. This study assessed and compared the population structures and regeneration potential of three vulnerable woody species—Diospyros mespiliformis Hochst., Prosopis africana (Guill. & Perr.) Taub. and Sterculia setigera Del.—in protected and unprotected areas in the Sudanian zone of Burkina Faso. The population structure and regeneration pattern of each species were compared between the North and South Sudanian sectors of Burkina Faso. The populations of all three species were unstable in both protected and unprotected areas. D. mespiliformis and P. africana displayed relatively good regeneration while P. africana lacked regeneration in unprotected areas. Regeneration was poor for S. setigera, regardless of protection status. The results suggest that the populations of the targeted species are unstable, regardless of the protection status of the area considered. This is probably due to the high anthropogenic pressure facing natural resources and raises serious concerns about the effectiveness of the protected areas in conserving biodiversity. Urgent measures are needed to ensure effective and efficient management and conservation of biodiversity in the protected areas of Burkina Faso.     

Social and environmental trade-offs in tree species selection: a methodology for identifying niche incompatibilities in agroforestry

Natural resource degradation in highland regions is of increasing concern to the global community due to its role in aggravating poverty and the loss of environmental services to local and downstream users. The integration of trees into smallholder farming systems has been promoted as a means to enhance rural livelihoods while reversing the degradation of soil, water, biodiversity and related environmental services. Yet in addition to these benefits, negative impacts of trees on certain stakeholders or system components have also accompanied such efforts—suggesting that important trade-offs accompany afforestation. This paper presents a methodology for diagnosing problems stemming from cultivation of certain tree species in specific landscape niches. Data derived from the application of this methodology in two sites in the eastern African highlands are presented. Participatory diagnoses of landscape-level problems suggest that the negative impact of trees on water resource availability and crop yield are of critical concern to smallholder farmers. Ethnoecological data highlight the properties of different tree species that determine their suitability to specific farm and landscape niches. These data point to important opportunities for more socially- and environmentally-optimal integration of indigenous and exotic tree species into agricultural landscapes, and highlight the critical importance of local knowledge in forging solutions appropriate to contemporary realities.     

Ecological, cultural, and economic approaches to managing artisanal fisheries

Approaches towards the management of artisanal fisheries have been enlightening the scientific literature for approximately the last 20 years. Coming from diverse disciplines such as anthropology, biology, economy, and ecology (especially human ecology), these approaches have dealt with common theory, strategies for cooperation, decision-making models, cultural contexts, and local knowledge. Fishery management depends on an understanding of the interactions between humans and aquatic resources, and in case of indigenous or of native populations, forestry resources are also considered for livelihoods. Acquiring an understanding of the local knowledge about fish and other resources, of collective local arrangements and institutions, of market interactions, and of the decision-making processes of fishers is fundamental for the management of artisanal fisheries. This review includes historical and current approaches associated with the management of artisanal fisheries. These approaches include the following: (a) cultural and human ecological approaches, including ecological models such as optimal foraging theory; (b) institutional approaches, including processes of cooperation associated with local knowledge and institutions; and (c) current ecological-economic propositions towards fishery management, such as payments for environmental services. This revision is illustrated through examples, in particular, of data collected among coastal artisanal fisheries of the SE Atlantic Forest in Brazil.     

Using the useful: characteristics of used palms in south-eastern Ecuador

Plant families differ greatly with regard to their usefulness to humans. Within families there are also large differences in the usefulness between species; some are used for many different purposes, while most are used for few or no purposes. Which ones and to what extent species are used often varies between areas and cultural groups. To better understand variation in speciesȁ9 usefulness we studied the use of different palm species (Arecaceae) among two socio-cultural groups (one indigenous and one colonist group of mixed ethnic descent) living in the same area. We used regression and correlation analyses to determine to what degree use is related to ecological and morphological characteristics, to geographical differences in abundance, and to peopleȁ9s perceptions of speciesȁ9 availability. We found that abundance and height were the most important characteristics related to use, possibly due to the effect of height and abundance on salience, search time, and (for height) suitability for different purposes. Abundance was most important for palm heart extraction, probably due to the opportunistic nature of this activity. There was no difference between socio-cultural groups with regard to the relationship between palm abundance and use, but abundance seemed to be more decisive for people who used moderate amounts of palms. Finally, it was seen that peopleȁ9s estimates of palm abundance were not related to our measurements of abundance, which may be due to use of different spatial scales in evaluating abundance and to the subjective nature of terms such as “rare” and “abundant”.     

Intrapopulation spatial segregation in bream (<Emphasis Type="Italic">Abramis brama</Emphasis>) and roach (<Emphasis Type="Italic">Rutilus rutilus</Emphasis>) in the Rybinsk Reservoir

In the course of studies on mass fish species (bream and roach) in water bodies of the Upper Volga basin, intraspecific groups of individuals have been distinguished. Conditions and possible mechanisms of spatial differentiation of these groups are considered. The intrapopulation divergence of individuals by some adaptive characters, primarily behavioral, enables them to utilize alternative resources, which provides for more efficient use of the environment by populations.     

Bushmeat consumption and its implications for wildlife conservation in the semi-arid region of Brazil

Hunting plays an important socioeconomic role in the semi-arid region of Brazil, by supplying meat and other products. Nevertheless, there is a lack of information on which species are most used by the local populations and what are the implications for conservation of exploited animals. This paper explores the bushmeat consumption in the Brazilian Caatinga region, where wild animals comprise an important protein source. A questionnaire was used to gather information from hunters, and the consumption of bushmeat by their families was monitored. Interviews revealed that 58 vertebrate species could potentially be consumed as bushmeat, but the samples provided by the monitored families comprised only 28 species. Birds were the animals most consumed, followed by mammals, although the biomass of both groups was similar. The consumption of bushmeat was not correlated with hunters’ socioeconomic data (income, age or schooling). Hunters recognized that the populations of some game species appeared to be declining, showing that bushmeat consumption, together with the cultural, economic and social aspects of the human populations involved in hunting, should be considered when discussing the conservation of animal resources in the Caatinga region.     

Local ecological knowledge and incremental adaptation to changing flood patterns in the Amazon delta

The need for understanding the factors that trigger human responses to climate change has opened inquiries on the role of indigenous and local ecological knowledge (ILK) in facilitating or constraining social adaptation processes. Answers to the question of how ILK is helping or limiting smallholders to cope with increasing disturbances to the local hydro-climatic regime remain very limited in adaptation and mitigation studies and interventions. Herein, we discuss a case study on ILK as a resource used by expert farmer-fishers (locally known as Caboclos) to cope with the increasing threats on their livelihoods and environments generated by changing flood patterns in the Amazon delta region. While expert farmer-fishers are increasingly exposed to shocks and stresses, their ILK plays a key role in mitigating impacts and in strengthening their adaptive responses that are leading to a process of incremental adaptation (PIA). We argue that ILK is the most valuable resource used by expert farmer-fishers to adapt the spatial configuration and composition of their land-/resource-use systems (agrodiversity) and their produced and managed resources (agrobiodiversity) at landscape, community and household levels. We based our findings on ILK on data recorded for over the last 30 years using detailed ethnographic methodologies and multitemporal landscape mapping. We found that the ILK of expert farmer-fishers and their “tradition of change” have facilitated the PIA to intensify a particular production system to optimize production across a broad range of flood conditions and at the same time to manage or conserve forests to produce resources and services.     

Analysis of Trophic Indices in Gypsy Moth (Lymantria dispar L.) Larvae from Two Geographic Populations

Specific features of larval feeding in two geographic populations of the gypsy moth are considered. It is shown that in larvae reared on an artificial diet, trophic indices depend on several factors, including the age and sex of larvae and the food plant on which the parental generation developed in nature. It is shown that larval micropopulations belonging to the same geographic population but feeding in nature on different plant species differ from each other to a greater extent than those of different geographic populations feeding on the same species.     

Conservation value of an exotic species: the case of coconuts on the Kayapo indigenous lands, south-eastern Amazonia

In a meeting between FUNAI (the Brazilian Indian National Foundation) and the Kayapo in the Kayapo village of Aukre, in October 2005, the Kayapo Indians requested support to increase the culture of coconuts (Cocos nucifera) in their lands. The introduction of exotic species is a cause of biological diversity loss throughout the world. However, this is by no means applicable to all kinds of exotic species. We argue that the culture of coconuts may actually be a useful tool for the conservation of this country’s indigenous lands, despite criticism to the contrary. It may also be useful as source for raw material for the indigenous people who are presently experiencing a population boom. For the Kayapo of south-eastern Amazonia, such a demographic explosion, coupled with their increasing dependence on money to purchase industrialized goods, tend to substantially increase the pressure on their lands, which still contain a substantial amount of well-preserved seasonally-dry Amazonian forests. We investigated the actual economic relevance of coconuts for the Kayapo by measuring human and coconut populations and found that this exotic palm is not important for the subsistence of these Indians, due to coconut scarcity, and that such importance is not forthcoming. In the Amazon, coconuts may be particularly useful for the Indians’ nutrition due to the high energetic value of the solid endosperm of the mature fruit. Therefore, given the importance of indigenous lands for the conservation of the Amazonian forests, the encouragement of subsistence coconut cultures in indigenous lands is defensible as a measure for the conservation of biodiversity.

Involving local farmers in rehabilitation of degraded tropical forests: some lessons from Ghana

The role of community-based plantation development in forest rehabilitation and poverty alleviation is a pressing issue for the government of Ghana. In this paper, we present an analysis of the prospects of a community-based plantation using taungya systems and indigenous trees as means to forest rehabilitation and livelihood improvement in Ghana. The project management strategies, communication process and incentive mechanism and their impact on local participation are discussed with the aim to recommending a mechanism through which local farmers can best be involved in rehabilitation of degraded sites in the future in Ghana. Data were collected through a survey using personal interviews of 431 farming households and ten key informants from ten communities living in scattered hamlets in and around forests reserves. The results show a high rate of local participation in project tree planting activities. Four years after the project’s initiation, about 250 ha of plantations had been established using twelve priority indigenous and one exotic species and farmers had indicated improvement in their farming practices and availability of food and forest products. Restoring forest quality as a timber resource and associated values, getting money, food stuff and timber and non-timber for domestic use, and having access to fertile land for farming were the top three issues prioritised by respondents as motivational factors for engaging in the project activities. Overall, this project demonstrates that reversing tropical forest degradation is possible. For this we need local involvement in tree domestication combined with activities that addresses livelihood needs and environmental concerns. This case also demonstrates the prospects of utilising indigenous tree species, not only exotic species that dominated tree planting in the past, for plantations and landscape rehabilitation in Ghana.

Rapid ethnobotanical diagnosis of the Fulni-? Indigenous lands (NE Brazil): floristic survey and local conservation priorities for medicinal plants

This study was developed as part of the project ??Studies for Environmental and Cultural Sustainability of the Fulni-ô Medical System: Office on handling medicinal plants??. The Fulni-ô people are located in Pernambuco State, Northeastern Brazil. One of the components of this project was an ethnobotanical diagnosis of the indigenous land, where a phytosociological survey was performed in an area of Caatinga vegetation, located at Ouricuri settlement. Based on these ethnobotanical data, we calculated a conservation priority index aiming to rank species that should receive immediate attention from the Fulni-ô people. We identified 44 woody plants, 50% of which have a medicinal use. Among these, six plants were considered highly vulnerable and in need of immediate conservationist attention, in order to ensure the perpetuation of these species and the sustainability of traditional therapeutic practices of the Fulni-ô: Anadenanthera colubrina, Myracrodruon urundeuva, Lippia sp., Spondias tuberosa, Maytenus rigida, and Sideroxylon obtusifolium. We recommend the direct involvement of the Fulni-ô people in the conservation and the management of local resources by implementing a management plan and monitoring strategies for the populations of plants considered most important by the indigenous group.     

Ethnosciences––A step towards the integration of scientific and indigenous forms of knowledge in the management of natural resources for the future

Integration of indigenous knowledge and ethnoscientific approaches into contemporary frameworks for conservation and sustainable management of natural resources will become increasingly important in policies on an international and national level, both in countries that are industrialised and those that have a developing status. We set the scene on how this can be done by exploring the key conditions and dimensions of a dialogue between ȁ8ontologiesȁ9 and the roles, which ethnosciences could play in this process. First, the roles of ethnosciences in the context of sustainable development were analysed, placing emphasis on the implications arising when western sciences aspire to relate to indigenous forms of␣knowledge. Secondly, the contributions of ethnosciences to such an ȁ8inter- ontological dialogueȁ9 were explored, based on an ethnoecological study of the encounter of sciences and indigenous knowledge in the Andes of Bolivia, and reviewed experiences from mangrove systems in Kenya, India and Sri Lanka, and from case-studies in other ecosystems world-wide, incl. Australia, Burkina Faso, Ecuador, Ethiopia, Guatemala, Indonesia, Nepal, Niger, Philippines, Senegal, South-Africa and Tanzania.     

Evaluating Consumer Understanding of the Swedish Meat Guide—A Multi-layered Environmental Information Tool Communicating Trade-offs When Choosing Food

To facilitate the choice of more sustainable animal-based products in the diet, a Swedish meat guide providing complex, multi-layered environmental information to non-experts has been developed. This study evaluated reception of this guide by consumers. In five focus groups, participants (“interested consumers”) carried out a joint environmental and animal welfare ranking assignment to test understanding and use of the guide. The type and detail of indicators (e.g. carbon footprint) in the meat guide suited the audience. The guide stimulated discussion on ethical issues and quality aspects of meat, revealed perceived obstacles to reducing meat consumption and provided an understanding that any food product chosen comes with trade-offs.
