Rethinking the contribution of indigenous management in small-scale water provision among selected rural communities in Cameroon

This paper describes the pro-active role of rural communities in negotiating livelihood and sustenance through the improvement of some of their local water sources. It discusses the strategies put in place to ensure the availability of water, one of the world’s scarcest natural resources. Despite some external assistance, local communities are increasingly shouldering the responsibility of ensuring the availability of water through self-reliant efforts. These attempts are being undermined by a high incidence of waterborne and water-related diseases, which are impacting on health, and hygiene and other health care delivery systems. The management of potable water is proving to be a herculean task for most communities after the departure of funding partners. To guarantee the proper maintenance of pipe borne water schemes, communities are rethinking their strategies as they grapple with difficulties to put in place viable techniques for sustainability of water supply schemes.     

Experiences with restoration of inland freshwater wetlands in the Netherlands: lessons for science and policy-making

The past decade has seen important changes in the approach to water management issues in the Netherlands. Urban development, recreational demands, agriculture, nature conservation and other space demanding functions compete with water management objectives in their claims for space. An analysis of some recent water management projects illustrates that the implementation of the new water management approach is not always easy. Catchment-based multifunctional projects encounter major constraints. These constraints are: 1) national goals versus local constraints; 2) limited sense of urgency; 3) lack of institutional coordination in the water management community; 4) unclear views over nature conservation, and; 5) limited understanding of wetland functioning in relation to flood risk management. We promote platforms for collaborative planning as a way to improve stakeholder participation in early stages of decision-making. Negotiation and mediation support tools can enable stakeholders and mediators to formulate the problems that need to be addressed more effectively. Early involvement of stakeholders in the planning process is almost a condition for successful implementation; however, it is no guarantee of success, and not all conflicts can be solved. Therefore assessment of the costs and benefits of different parties is important for compensation schemes to gain broad social acceptance.     

Building climate change resilience through local cooperation: a Peruvian Andes case study

Many of the problems faced by international projects intending to create adaptive social–ecological systems for climate change stem from lack of stakeholder engagement, limited understanding of local political, economic, and environmental complexities, and restricted time. Local organizations focused on conservation and development might have an advantage in creating adaptive social–ecological systems because they understand local processes and are involved with communities for extended periods of time. A local non-governmental organization, Asociación Ecosistemas Andinos (ECOAN), works in twenty-one communities in the Andean highlands outside of Cusco to conserve the endangered Polylepis forests. As part of the conservation project, ECOAN supports community-led development projects such as building greenhouses. Data for this project were gathered through interviews (with community members in three different communities, ECOAN staff, and donors) and participant observation. This paper shows that ECOAN’s extensive use of participation has led to community ownership of the conservation and development projects. The communities’ close connections to the Polylepis project contribute to resilience through creating networks, extending the local environmental ethic to the Polylepis trees, supporting projects that diversify and strengthen community sustenance, and contributing to the growth of economic activities. This case study provides a positive example of the potential for local organizations and people to take charge of their own resiliency efforts where international projects and protocols may otherwise prove ineffective.     

From poverty trap to ecosystem service curse

In spite of broad and positive expectations, payments for ecosystem services (PES) can bring about unexpected and negative consequences, especially in terms of their impacts on the well-being of local communities dependent on ecosystems. Based on numerous observations of recurring problems with PES, we put forward an ecosystem service curse hypothesis (Kronenberg and Hubacek in Ecol Soc 18:art.10. doi: 10.5751/ES-05240-180110, 2013), that points to counterintuitive negative development outcomes for countries and regions rich in ecosystem services. The social and economic problems that we have been able to depict in many PES schemes reflect the persistence of maladaptive states in pursuit of sustainability. Instead of providing an opportunity to break out of poverty, these problems reflect entrapment, which is most often related to poor quality of institutions. Here we highlight the linkages between the ecosystem service curse hypothesis and the dynamic system stability landscapes discussed in this special issue. Our article consists of three parts in which we: (1) present the original ecosystem service curse hypothesis; (2) link this hypothesis to the broader discussions relevant to sustainability science; and (3) highlight the context of traps on which this special feature focuses.     

Correction to: Allocation of risk and benefits—distributional justices in mountain hazard management

As financing protection against mountain hazards becomes increasingly challenging and therefore investments have to be prioritized, dilemmas of justice emerge: some local governments and individuals benefit from natural hazard protection schemes, whereas others loose. Decisions on whom to protect often caused contradicting concepts of political understanding, which differ in interpretations of fair resource allocation and distribution. This paper analyses the impact of different philosophical schools of social justice on mountain hazard management in Austria. We used data from a spatially explicit, object-based assessment of elements at risk and compared potential distributional effects of three political jurisdictions. We found that—depending on the respective political direction—various local governments gain and others loose within the actual distributional system of mitigation strategies. The implementation of a utilitarian policy approach would cause that high income communities in hazard-prone areas would mainly benefit. Consequently, this policy direction would encourage the public administration to ignore their own failure in the past natural hazards management and prevention. On the other hand, following a Rawlsians approach mainly peripheral communities would gain from new policy direction who often show besides natural hazards problem mainly large socio-economic challenges. Finally, the most radical change would include the implementation of a liberalism policy, whereabouts the state only provides hazard information, but no further mitigation measures. These findings highlight the distributional consequences of future mountain hazard management strategies and point to the crucial selection of policy direction in navigating the selection of various adaptation schemes.

     

Perceptions of using low-quality irrigation water in vegetable production in Morogoro,Tanzania

This study was conducted to examine perceptions of the farmers and key informants on the use of low-quality irrigation water for vegetable production in urban and peri-urban areas in Morogoro, Tanzania. The methods used to collect data were farmer surveys (n = 60), focus group discussions (n = 4) and key informants interviews (n = 15). The results showed that the respondents had a positive perception on using low-quality irrigation water for vegetable production. The reported benefits include availability of water throughout the year, highest soil and crop nutrients in irrigation water, less costs of buying commercial fertilizers, vegetable production all year round, sustainable income generation from selling vegetables and also jobs creation in the community among farmers and vegetable sellers. Findings from Mann–Whitney U test and Kruskal–Wallis test score on farmers perception scales indicate an association between the source of low-quality water used and the respondents’ sex. Accordingly, female farmers had higher positive perception on the benefits of low-quality water compared to male farmers. Higher perception score was also observed among farmers who used polluted river water in irrigation vegetable production compared to farmers who used wastewater. Since low-quality irrigation water is a good strategy of coping with scarcity of freshwater for communities which have no alternative source of irrigation water, the study recommends multi-sectorial agencies across the country to be involved in formulating policies and creating health promotion awareness for safe use of low-quality water for benefit maximization and health risk reduction.     

Local vulnerability as an advantage: mangrove forest management in Pará state,north Brazil,under conditions of illegality

When ecosystems are threatened or scientific knowledge of the effects of human action is uncertain, legislative prohibition is often adopted. This paper examines how the criminalization of mangrove tree use affects ecosystem management outcomes. We explore the biological, economic and social sustainability effects of the legal ban on mangrove use on the coast of Bragança, Pará, north Brazil. There are two main categories of mangrove users in this area: firstly, local subsistence users who also derive some financial incomes from mangrove sale. Their mangrove use is intertwined with household livelihood strategies and they display self-initiated planning and action towards sustainable management; secondly, more mobile, purely commercial users who are responsible for most commercial mangrove exploitation and who employ regionally sequential, predatory resource exploitation strategies. These users are typically based at some distance from the exploited areas and share neither local livelihood strategies nor sustainability agendas. The current outright ban on any utilization of mangrove flora seems to undermine biological sustainability, is economically inefficient and generates normative insecurity, conflict and social polarization. The ineffectiveness of the outright legal prohibition of mangrove tree use in terms of sustainable coastal management leads us to investigate alternative management options. We suggest that the legalization of local mangrove utilization and the strengthening of local users rights and responsibilities to control outsiders in a co-management framework, as proposed in the Brazilian extractive reserves (RESEX) approach, is most likely to advance ecologically, economically and socially sustainable mangrove management. It is demonstrated that a legal recognition of local entitlements to mangrove trees would reduce social vulnerability and therefore move forest management outcomes into more desirable directions.

Influence of community-based natural resource management strategies in the resilience of social-ecological systems

Different social-ecological systems around the world are managed under community-based natural resource management (CBNRM) strategies. This paper analyses how CBNRM strategies influence the resilience of social-ecological systems to the disturbances they face, drawing upon the experience of three Latin American cases (two in Mexico and one in Colombia). The cases differ in their CBNRM approach and in the time these governance systems have been in place. By using a mixed-method approach, we review the socio-ecological history and describe each CBNRM characteristics. We then assess their resilience to socioeconomic and environmental disturbances through a set of indicators. We found that CBNRM strategies influence positively and negatively resilience and that internal decisions might address important threats. On the positive side, the social-ecological systems with longer tradition of CBNRM and more local buy-in of commonly agreed objectives appear to be more resilient to environmental challenges. But, internal governance factors such as power imbalances, poor income distribution, and gender inequities linked to CBNRM undermine resilience and foster out migration. Finally, communities appear to have limited capacities to cope with external disturbances such as global drivers of change or national policies that negatively affect their social-ecological resilience.

     

Rural women and agrotourism in the context of sustainable rural development: A case study from Turkey

As in many developing countries also in Turkey, agriculture is on the center of rural development and rural women are on the center of agriculture. Although they are main part as a major labor force at every stage of agricultural activity and undertake responsibilities such as domestic task and childcare, women do not profit from social and economic benefits proportionate to the responsibilities they have undertaken.Agrotourism is an alternative activity in the rural development process, which combines agriculture and tourism, improves natural resources, contributes the rural area socially and economically.The aim of this study is to examine the participation conditions of rural women to the agrotourism activities, which is considered as an option in the context of sustainable rural development, and to identify the possible social and economic implications of agrotourism on the rural womens life, after determining the situation and importance of rural women in the agricultural activity. This research was carried out in three villages of Kalecik district of Ankara and data gathered from group meetings and surveys.Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.     

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.

Adaptation to climate change and other stressors among commercial and small-scale South African farmers

Commercial and small-scale farmers in South Africa are exposed to many challenges. Interviews with 44 farmers in the upper Thukela basin, KwaZulu-Natal, were conducted to identify common and specific challenges for the two groups and adaptive strategies for dealing with the effects of climate and other stressors. This work was conducted as part of a larger participatory project with local stakeholders to develop a local adaptation plan for coping with climate variability and change. Although many challenges related to exposure to climate variability and change, weak agricultural policies, limited governmental support, and theft were common to both farming communities, their adaptive capacities were vastly different. Small-scale farmers were more vulnerable due to difficulties to finance the high input costs of improved seed varieties and implements, limited access to knowledge and agricultural techniques for water and soil conservation and limited customs of long-term planning. In addition to temperature and drought-related challenges, small-scale farmers were concerned about soil erosion, water logging and livestock diseases, challenges for which the commercial farmers already had efficient adaptation strategies in place. The major obstacle hindering commercial farmers with future planning was the lack of clear directives from the government, for example, with regard to issuing of water licences and land reform. Enabling agricultural communities to procure sustainable livelihoods requires implementation of strategies that address the common and specific challenges and strengthen the adaptive capacity of both commercial and small-scale farmers. Identified ways forward include knowledge transfer within and across farming communities, clear governmental directives and targeted locally adapted finance programmes.     

Farmer typology, future scenarios and the implications for ecosystem service provision: a case study from south-eastern Spain

Farming communities are increasingly expected to manage their agricultural activities in ways that ensure sustainable flows of a wide range of ecosystem services for society. The land use and management choices that farmers make are dependent upon their socio-economic characteristics and background, and in turn have important implications for the landscape and associated ecosystem services. Thus, a better understanding about the linkages between the characteristics of farmers, farm management and land use is important for managing multifunctional agro-ecosystems. In this paper, we first develop a typology of farmers for Torrealvilla catchment in Murcia, Spain, according to the characteristics of their households and farm management (e.g. the farmer’s age, household income, water access, land tenure and farm labour). This analysis distinguishes six types of farmers. Secondly, we analyse the link between farmer typology and the farmers’ responses to a number of scenarios. The scenarios describe different likely changes to agriculture in the catchment in terms of environmental constraints (irrigation water availability and rainfall pattern) and environmental policy regulation (water taxation and subsidies). This exercise enables us to explore the range of future land use changes that are likely to occur in the study area. The results indicate that: rain-fed agriculture is expected to experience gradual but extensive abandonment; vegetable/fruit farming and pig/animal rearing are likely to stagnate or even decline; and growing of grapes is likely to expand. Thirdly, we qualitatively evaluate how future land use changes are likely to affect key ecosystem services in the study area including future agricultural production and associated local income generation, erosion control, maintenance of the groundwater table and various cultural services associated with a heterogeneous agro-ecosystem. Particular changes such as expansion of grape production will increase food production and local income at the cost of further depletion of the aquifer and increased risk of salinisation. The outcomes of the study highlight that, to be effective, the design of agri-environmental schemes and other government interventions (e.g. specific compulsory regulations on farming practices and associated water use) should carefully take into account the characteristics of the farmers within the area of interest, their land uses and the possible diversity of responses to policy and environmental drivers. Opportunities exist for future studies quantifying the extent of the impacts of ecosystem service provision through formal models combining farmers’ land use decision-making and spatially explicit modelling of landscape processes.     

Development,local livelihoods,and vulnerabilities to global environmental change in the South American Dry Andes

Climate change will increasingly impact large areas of South America, affecting important natural resources and people’s livelihoods. These impacts will make rural people disproportionately more vulnerable, given their dependency on ecosystem services and their exposure to other stressors, such as new rules imposed by agribusiness and trends toward the commodification of natural resources. This paper focuses on the vulnerability of rural communities in Andean drylands of Argentina, Bolivia, and Chile, showing how different economic and political pathways lead to different levels of vulnerability. The paper begins with a brief discussion of the methodological and theoretical concept of vulnerability, which framed the research. Starting from the premise that global environmental change impacts are strongly linked to styles of development, the discussion explores the diverse institutional capital and governance schemes as well as different development styles in the case studies and their role in increasing or reducing local vulnerability to climate and water scarcity. Using a comparative perspective, the exposures and adaptive capacities of rural actors in three river basins are discussed, emphasizing situations that speak for the ways in which development styles counteract or magnify conditions of vulnerability. The analysis considers irrigated and non-irrigated agriculture, water property interests, different productive structures (viticulture, horticulture, etc.), producer typologies (large/small, export, etc.), and geographical location. Finally, the paper offers some insights about development style and adaptive capacities of rural people to overcome those vulnerabilities.     

Re-emphasizing sustainable development — The concept of ‘Evolutionability’ On living chances, equity, and good heritage

The principle of sustainable development is now 15-year-old. There are a lot of definitions and models for its explanation — ranging from triangles and prisms to eggs — but still its sense is diffuse. Moreover, important aspects like equity are not sufficiently taken into account.The following article takes a critical look on sustainable development. It shows logical, systemic, philosophic and ethic reasons for the re-development of substantial parts of the principle of sustainability. Based on the proposed Principle of Good Heritage it provides a rough outline of a future Concept of Evolutionability, comprising a first tentative for a definition of evolutionable development, aiming at achieving a more appropriate and more workable mainstream view of sustainability.Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.     

Formation of Rodent Communities in Arable Lands of Northern Eurasia

Rodent communities of crop fields have been demonstrated to fundamentally differ from rodent communities of natural biotopes. Communities dominated by Microtus arvaliss. lato, Mus musculus, and Apodemus agrariusoccupy the largest areas of arable fields in northern Eurasia. These are typical agrophiles. They usually rapidly colonize various crop fields, inhabit them seasonally or throughout the year, and successfully reproduce there, losing their connections with natural biotopes. Agriculture helps a few agrophilic species to flourish but reduces the general diversity of rodents.     

Culture as trigger for sustainability transition in the water domain: the case of the Spanish water policy and the Ebro river basin

There is a mounting body of literature dealing generally with the dynamics of transitions of human systems towards sustainability and specifically with the different stages and processes of transitions. However, the question of why transition processes occur in the first place remains largely unexplained. This paper explores the concept of transition triggers, such as culture or material resource scarcity, and provides a theoretical framework to explain the emergence of a transition and its relation to recent developments in Spanish water policy. We adapt the general framework provided by current transition theory and gather empirical evidence and insights from processes occurring within the Spanish policy context and the Ebro river basin in particular. Our results show that the sole existence of biophysical limits to water use or development cannot explain the start of a possible sustainability transition in this domain in Spain. Changes in the existing water policies in the direction of sustainability were not ignited by people directly affected by water scarcities but by a coalition of sensitive agents, mostly from academia, NGOs and local constituencies, who managed to articulate new identities, integrate multiple sources of policy relevant knowledge, and develop new values under the umbrella of the new water culture movement.

Ten years of international scientific cooperation in fisheries,aquaculture and coastal zones: some preliminary lessons

The paper examines preliminary experiences with international scientific cooperation in fisheries, aquaculture and coastal zone issues through 90 projects in successive European Research Framework Programmes (FP4–FP6: 1994–2006). FPs had increasingly ambitious objectives in response to international commitments, such as the Convention on Biological Diversity, the Millennium Development Goals, the Johannesburg Plan of Implementation and dialogue with partner regions. Sustainable aquatic food production in the context of respect for ecosystems was a central concern. Engagement with different social actors and attention to investment in education, people and institutions enabled uptake of research results in education, innovation and some impact. The emphasis in several recent projects on more integrated analyses and knowledge products in the public domain is an encouraging response to the growing crisis of aquatic resource systems. It is suggested that significant up-scaling will be required. This might be done through institutional internalisation and better translation of research results into policy developments supportive of transitions towards sustainable production systems and ecosystem rehabilitation. Capacity building to use research in novel ways and other enabling mechanisms need to be put in place to increase societal and environmental benefits of the research.

Climate change and natural disasters: macroeconomic performance and distributional impacts

Commonly occurring natural events become natural disasters when they affect the population through death and injury, and/or through the destruction of natural and physical capital on which people rely for their livelihood and quality of life. Climate change plays a role in that it tends to increase the frequency and intensity of weather-related natural disasters. Additionally, climate change may put people at risk by influencing access to water, coastal flooding, disease and hunger, and leaving them with a more degraded environment, leading, in turn, to increased vulnerability. The purpose of this paper is to present a review and synthesis of the literature and case studies addressing differential impacts of climate change-related natural disasters on a society and its economy. Developed and developing countries show different vulnerabilities to natural disasters. Even within countries, impacts vary significantly across population and economic sectors. When losses from natural disasters are large, their cumulative effect can have notable macroeconomic impacts, which feed back to further pronounce existing income inequalities and lower income levels. Impacts tend to be most pronounced for women, the young and elderly, and people of ethnic or racial minorities.

Urbanisation Without Development: Environmental and Health Implications in African Cities

Sustainable development advocates for a balance between socio-economic development and the environment in the pursuit of human advancement. In Africa, high population growth and inadequate infrastructure in urban areas exert pressure on the environment and this threatens the health and wellbeing of urban residents. The population of the African continent until the 1960s was predominantly rural. This scenario has taken a swift turn and some of the major shifts in the global urbanisation process are taking place on the continent. Factors including natural increase in the population, rural–urban migration, strife and hunger leading to the internal displacement of populations have exacerbated the urbanisation process in Africa. The situation has been worsened by the imposition of Western development policies, including structural adjustment programmes on African nations, which has eroded the subsistence base of rural agricultural communities and further ignited rural urban migration. The failure of industry to absorb the increasing labour force has created massive unemployment and deepening poverty crisis in urban centres. Inadequate provision of infrastructure and services to meet the growth in urban populations has resulted in inefficient spatial development of urban centres, the proliferation of squatter settlements, inadequate basic amenities including potable water, sanitation and waste disposal. Poor environmental sanitation has resulted in the upsurge of infectious diseases and deteriorating urban health. Urban populations in Africa are also the worst affected by newly emerging diseases, particularly HIV/AIDS. The poor bear a disproportionately large share of the problems due to their particular vulnerability to environmental and health risks.
