Qualifying irrigation system sustainability by means of stakeholder perceptions and concerns: lessons from the Segarra‐Garrigues Canal,Spain

When planning interventions, water and land resource managers increasingly need to take the opinions of stakeholders into account. In the present study, stakeholders’ concerns in a multifunctional water system are assessed, with a focus on the debate about the sustainability of irrigation projects in stressed and competing water contexts. The selected case study pertains to the Segarra‐Garrigues irrigation canal (Spain), the promotion of which has generated social debate and mobilization, as well as pronouncements from European authorities for ensuring its environmental sustainability. Data was collected through semi‐structured interviews and analysed by means of a new codification system for identifying the affinities and conflicts arising from existing water demands. Results show that sustainability concepts are more present in civil society than in public administration and private services or the rural community. However, social sustainability and environmental sustainability are a priority for most stakeholders, while the economic perspective of sustainable development has been conditioned by the first two. These results can be used by relevant authorities as a first step in customizing their interventions, as they provide a clear initial idea of what stakeholder priorities are in the framework of sustainable development.     

Rural Income and Forest Reliance in Highland Guatemala

This paper estimates rural household-level forest reliance in the western highlands of Guatemala using quantitative methods. Data were generated by the way of an in-depth household income survey, repeated quarterly between November 2005 and November 2006, in 11 villages (n = 149 randomly selected households). The main sources of income proved to be small-scale agriculture (53 % of total household income), wages (19 %) and environmental resources (14 %). The latter came primarily from forests (11 % on average). In the poorest quintile the forest income share was as high as 28 %. All households harvest and consume environmental products. In absolute terms, environmental income in the top quintile was 24 times higher than in the lowest. Timber and poles, seeds, firewood and leaf litter were the most important forest products. Households can be described as ‘regular subsistence users’: the share of subsistence income is high, with correspondingly weak integration into regional markets. Agricultural systems furthermore use important inputs from surrounding forests, although forests and agricultural uses compete in household specialization strategies. We find the main household determinants of forest income to be household size, education and asset values, as well as closeness to markets and agricultural productivity. Understanding these common but spatially differentiated patterns of environmental reliance may inform policies aimed at improving livelihoods and conserving forests.     

Measuring forest ecosystem sustainability: A resource accounting approach

A new environmental paradigm has emerged, reflecting a change in the public's understanding of resource sustainability. Forest policy makers need to be better informed about such changes to achieve economic, social, and environmental objectives in a manner that balances human needs and aspirations with ecosystem constraints. As an aid to this task, a forest resource accounting system based on the key concept of natural capital could help reshape forest policies to provide an even wider spectrum of benefits for both present and future generations by maintaining and enhancing the productive capacity of forest capital. Such a resource accounting system would provide a tool for integrating multidimensional information requirements in measuring the health of both forest ecosystems and economic systems. This paper outlines some of the features of this accounting system and proposes and framework that would integrate economic and ecological characteristics of natural resources. Forest resource accounting is urgently needed to achieve the sustainability goals of ecosystem management.     

Resolving the Conflict Between Ecosystem Protection and Land Use in Protected Areas of the Sierra Madre de Chiapas,Mexico

Livelihoods of people living in many protected areas (PAs) around the world are in conflict with biodiversity conservation. In Mexico, the decrees of creation of biosphere reserves state that rural communities with the right to use buffer zones must avoid deforestation and their land uses must become sustainable, a task which is not easily accomplished. The objectives of this paper are: (a) to analyze the conflict between people’s livelihoods and ecosystem protection in the PAs of the Sierra Madre de Chiapas (SMC), paying special attention to the rates and causes of deforestation and (b) to review policy options to ensure forest and ecosystem conservation in these PAs, including the existing payments for environmental services system and improvements thereof as well as options for sustainable land management. We found that the three largest PAs in the SMC are still largely forested, and deforestation rates have decreased since 2000. Cases of forest conversion are located in specific zones and are related to agrarian and political conflicts as well as growing economic inequality and population numbers. These problems could cause an increase in forest loss in the near future. Payments for environmental services and access to carbon markets are identified as options to ensure forest permanence but still face problems. Challenges for the future are to integrate these incentive mechanisms with sustainable land management and a stronger involvement of land holders in conservation.     

The miombo woodlands at the cross roads: Potential threats, sustainable livelihoods, policy gaps and challenges

The Miombo, the most extensive tropical woodland formation of Africa directly supports the livelihoods of over 100 million people through the provision of many tree products and ecosystem services essential to both the rural and urban communities. While the destruction of the Miombo has often been blamed on the rural communities dwelling near the forest resources, many urban dwellers depend heavily on the various products derived from the woodlands. This paper highlights the importance of the Miombo in the livelihoods of rural people, the potential threats to this ecosystem and opportunities for its sustainable management. About 70% of energy consumed in southern Africa is in the form of fuelwood or charcoal. The economic importance of the Miombo especially from non-timber forest products (NTFPs) is usually understated due to their perceived non-economic value yet they play an important role in sustaining livelihoods of forest dependent people in the miombo ecoregion. The Miombo also contributes to health services through the use of medicinal plant and products, in some cases, contributing up to 80% to rural health, including helping in coping with effects of HIV/AIDS, malaria and several diseases. The possibility of developing payment for environmental services schemes through public–private partnerships, and community-based sustainable management models are proposed. Through conservation and commercialization of some of the products and services, there is a potential to provide income and improve the livelihood of people involved in the trade along the value chain.     

Environmental Subsidiarity as a Guiding Principle for Forestry Governance: Application to Payment for Ecosystem Services and REDD+ Architecture

This article describes and proposes the “environmental subsidiarity principle” as a guiding ethical value in forestry governance. Different trends in environmental management such as local participation, decentralization or global governance have emerged in the last two decades at the global, national and local level. This article suggests that the conscious or unconscious application of subsidiarity has been the ruling principle that has allocated the level at which tasks have been assigned to different agents. Based on this hypothesis this paper describes the principle of subsidiarity and its application to environmental policies within forest governance and proposes the “environmental subsidiarity” principle as a critical conceptual tool for sustainable resource management. The paper explains as an example how “environmental subsidiarity” is the key principle that can link payment for ecosystem services (PES) with environmental public policies and applies this principle with all its political consequences to reducing emissions from deforestation and forest degradation, and enhancing forest carbon stocks in developing countries (REDD+) architecture. It concludes by showing how the adoption of “environmental subsidiarity” as a ethical principle could help to maximize benefits to all stakeholders involved in PES schemes such as REDD+.     

On measuring wealth: a case study on the state of Queensland

In order for policy makers to plan effectively for sustainable development, there is a need for measures of welfare that consider changes in the natural capital stock. Current measures based on conventional national accounting are flawed because they are based solely on flow measures and do not account for environmental effects. In this paper, we use an expanded measure of wealth to estimate the value of natural capital for Queensland. The state's stock of natural capital is valued at A dollar 355.6 billion, of which non-timber forest resources account for 45.3%, ecosystem services 20.0%, and mineral resources 17.6%. This figure is a conservative estimate of the true value since some significant components such as the ecological and life-support functions of the environment are excluded. The estimates highlight the relative importance of different forms of natural capital and can be used to draw the attention of policymakers to the need to give adequate weight to the value of such services in decision-making processes.     

A disclosure of social and environmental results/economy resulting from the implementation of reverse logistics and final disposal of the post‐consumption product: The case of computer peripherals industry

This research was conducted with the objective of determining and evidencing the social and environmental/economic results from the implementation of a reverse logistics program providing for the recycling, reuse, and, when necessary, final, environmentally correct disposal of post‐consumption products and product wastes by a multinational manufacturer of computer peripherals with an operation based in the city of São Paulo, Brazil. The reverse logistics process (logisticareversa, or, in this paper, LR) was intended to meet the objectives and principles of the regulatory framework defined in the National Solid Waste Policy (PNRS) in Brazil. A single case study was carried out. The results showed that after the adoption of the solid waste management policy, the study company no longer disposed of 1,413,552 kilograms (kg) of materials classified as mixed iron, polystyrene, cardboard, toner powder, and plastic in landfills. The LR process made a profit in two companies: the company surveyed made, in Brazilian reais (R), R$ 9,188,185.51, and the company contracted to carry out the process made, R$ 411,325.97. This latter profit is called by us the “social profit.” The measurement of the environmental/economic, social, and financial results by internalizing the expenses of the LR program into the costs of production shows that reuse and recycling better meets the needs of society and the company than landfilling these post‐consumption materials. Furthermore, the use of cost accounting allows the verification of other goals not indicated in the current model, such as the generation of employment, income, mitigation of environmental problems, and the profit earned by the company contracted to implement the LR process. We also conclude that cost accounting makes it possible to obtain necessary information for decision makers, who are seeking to neutralize environmental impacts and promote sustainable development, thus harmonizing the economic, social, and environmental aspects, to understand the impacts of the LR process.     

Economic Valuation of the Non-use Attributes of a Wetland: A Case-study for Lake Kerkini

Wetlands are an environmental feature which deliver a variety of market and non-market goods and services. Established environmental economic theory separates the value of these goods and services into direct-use values, indirect-use values and non-use values. Given appreciation of all three, measurements can be derived to demonstrate the amount of public money that it may be feasible to allocate to the sustainable management of wetlands. However, in many cases, non-use values are ignored and the total economic value of wetlands can be severely undervalued. As a result, inadequate resources are fed into their management and environmental degradation occurs due to inappropriate commercial exploitation of the natural resource. Lake Kerkini, in northern Greece, is one such wetland area threatened by undervaluation and overexploitation for commercial purposes, and a resource whose management would benefit from the realization of non-use values. This study therefore uses the contingent valuation method to place a value on the non-use attributes of Lake Kerkini. It also examines the relationship between the revealed non-use values and the distance people live from the lake, highlights the personal characteristics which appear important in determining total willingness to pay and breaks total non-use value down into its component parts to suggest the most important non-use elements. The paper concludes that sustainable management of the lake is justified and provides evidence that substantial public monies are potentially available to protect and enhance the environmental value of the resource.     

Transhumance in Central Anatolia: A Resilient Interdependence Between Biological and Cultural Diversity

Transhumance is a resource efficient means of livestock production by seasonally moving grazing animals to utilize pastures between varying ecological zones. This article investigated the interrelationship between the environmental services the transhumant provides whilst maintaining its cultural heritage and theorized what the cultural and environmental impacts would be if the practice of transhumance were to vanish. The authors interviewed 45 transhumant families during their 2015 seasonal migration through the Taurus Mountains and in their settled tent sites in Central Anatolia. The interview topics related to geography of the region, migration routes, natural resource constraints and opportunities, animal husbandry, grazing strategies and their income sources. By practicing agro-ecological principles over millennia, the research showed that the transhumant has helped shape a complex mosaic of habitats in one of Mediterranean’s most interesting ecosystems. The mobile pastoralist with conservation and natural resource management skills over a long period has reduced erosion control, improved soil quality and deterred the likelihood of forest fires, whilst weaving a resilient social web. The survey also indicated a clear link between social and ecological resilience emphasizing that sustainable development relies on the interconnectedness between biological and cultural diversity. The study recommends special provisions be made by the Turkish government for the educational needs for the children of the transhumant, provide initiatives for improved trading of their produce, introduce law enforcement for oppressive behavior against them and finally support the pastoralists to attain world heritage listing as a unique and an irreplaceable culture for the future welfare of humankind.     

绿色消费的社会治理体系研究

Water resources and development of women in arid regions in northern China

The total land area in China affected by desertification has grown over time due mainly to rapid population growth and environmental degradation. Arid and semi-arid regions now comprise approximately one-third of the country's land area. Women in arid areas suffer from the harsh environment as well as from discriminatory attitudes tied to the general expectations of women's role in society. Discrimination against women, high rates of illiteracy, poor health care, society's failure to recognize women's work, and insufficient social services result in illness, poverty, and low social status among women. The material poverty and lack of knowledge and education among women living in arid areas are discussed, as well as what women can do to alleviate poverty and improve the environment in arid areas. With regard to policies which could lead to sustainable development, the author discusses improving women's education in arid regions, public policies designed to improve women's conditions, ways to involve women in environmental protection, encouraging migration to reduce environmental degradation, and improving childbearing conditions.     

Carbon accounting rules and guidelines for the United States forest sector

The United States Climate Change Initiative includes improvements to the U.S. Department of Energy's Voluntary Greenhouse Gas Reporting Program. The program includes specific accounting rules and guidelines for reporting and registering forestry activities that reduce atmospheric CO2 by increasing carbon sequestration or reducing emissions. In the forestry sector, there is potential for the economic value of emissions credits to provide increased income for landowners, to support rural development, to facilitate the practice of sustainable forest management, and to support restoration of ecosystems. Forestry activities with potential for achieving substantial reductions include, but are not limited to: afforestation, mine land reclamation, forest restoration, agroforestry, forest management, short-rotation biomass energy plantations, forest protection, wood production, and urban forestry. To be eligible for registration, the reported reductions must use methods and meet standards contained in the guidelines. Forestry presents some unique challenges and opportunities because of the diversity of activities, the variety of practices that can affect greenhouse gases, year-to-year variability in emissions and sequestration, the effects of activities on different forest carbon pools, and accounting for the effects of natural disturbance.

Evidence of the impacts of the national housing programme on the accessibility of the low‐income population in Rio de Janeiro

The Brazilian shift from a primarily rural to a more urban society has created major challenges that public policies must address. One of the most relevant challenges is deep social exclusion in urban areas, especially in terms of adequate housing and access to urban opportunities (e.g., jobs, housing, and services). In this context, land use and transport planning play a critical role in the sustainable development agenda. The work presented here analyses the accessibility of low‐income dwellings licenced under the Brazilian housing programme to the low‐income population. To evaluate the accessibility of the programme's target population, a case study was conducted in the city of Rio de Janeiro, where 58,000 homes licensed under the programme were analysed using GIS tools in terms of the present public transport network and the location of the homes. The amount of time it takes to access public transport on foot and the homes’ locations in relation to major urban opportunities were also analysed. Finally, the same analysis was performed for the future transport network, and the results of the two analyses were compared to identify the scope of the legacy generated by investments in preparation for the 2016 network.     

Sustainable forestry management in developing countries

The central message of this paper is that natural forests have multiple uses and multiple users. The paper describes the crisis in Asian forestry and four failures which lie behind the crisis. The first failure is related to economic policy which has consistently underpriced timber, not accounting for the true cost of replacing the felled trees or the value of non-timber goods and services (including environmental services). The second failure stems from the lack of community involvement in managing forests. The third failure is that of forestry institutions which have not been able to adapt to changes required to meet new challenges — away from timber extraction towards environmental services and social forestry. The fourth failure arises from technological constraints, including difficulties in carrying out long-term research (to cover the 20–40 year time horizon in the forestry sector) and ineffective application of research results. A number of specific suggestions for moving toward sustained yield management in Asia are presented. The sustainable management of forests in Asia is crucial not only for indigenous peoples, the environment and economies of the countries of Asia, but also for the biodiversity and health of the global environment.     

China’s Classification-Based Forest Management: Procedures,Problems, and Prospects

China’s new Classification-Based Forest Management (CFM) is a two-class system, including Commodity Forest (CoF) and Ecological Welfare Forest (EWF) lands, so named according to differences in their distinct functions and services. The purposes of CFM are to improve forestry economic systems, strengthen resource management in a market economy, ease the conflicts between wood demands and public welfare, and meet the diversified needs for forest services in China. The formative process of China’s CFM has involved a series of trials and revisions. China’s central government accelerated the reform of CFM in the year 2000 and completed the final version in 2003. CFM was implemented at the provincial level with the aid of subsidies from the central government. About a quarter of the forestland in China was approved as National EWF lands by the State Forestry Administration in 2006 and 2007. Logging is prohibited on National EWF lands, and their landowners or managers receive subsidies of about 70 RMB (US$10) per hectare from the central government. CFM represents a new forestry strategy in China and its implementation inevitably faces challenges in promoting the understanding of forest ecological services, generalizing nationwide criteria for identifying EWF and CoF lands, setting up forest-specific compensation mechanisms for ecological benefits, enhancing the knowledge of administrators and the general public about CFM, and sustaining EWF lands under China’s current forestland tenure system. CFM does, however, offer a viable pathway toward sustainable forest management in China.     

Livelihood Sustainability and Community Based Co-Management of Forest Resources in China: Changes and Improvement

Community-based co-management (CBCM) has been applied in some communities near natural reserves in China. This paper uses Gansu Baishuijiang National Natural Reserve in China as a case study for livelihood improvements under CBCM projects. We demonstrate change from 2006 to 2010 in five classes of livelihood capital (social, human, natural, physical and financial capitals), illustrating the effectiveness of CBCM projects. Specifically, there are increases in mean family income and improvements in forest conservation. However, some problems in the design and implementation of CBCM projects remain, including the complicated social and political relationship between government and community, social exclusion and uneven application of benefits within communities, and the lack of integration of indigenous cultures and traditional beliefs. Attention for special groups in community and improving the design of CBCM Projects. Study shows that under the cooperation of government, CBCM projects and local community residents, the harmonious development of sustainable livelihood improvement and forest resources conservation will be an important trend in the future.     

Toward energy and livelihoods security in Africa: Smallholder production and processing of bioenergy as a strategy

The past few years have seen a phenomenal rise in the production and consumption of biofuels and biodiesel at the global level. This development is of special significance to Africa, where about 550 million people (75% of the total population in Sub‐Saharan Africa) depend on traditional biomass (wood, charcoal, cow dung, etc.) and lack access to electricity or any kind of modern energy service. Derived from plants and agricultural crops, biofuels and biodiesel represent modern forms of bioenergy and more efficient use of biomass energy. Beyond efficiency, modern bioenergy offers tremendous opportunities to meet growing household energy demands, increase income, reduce poverty, and mitigate environmental degradation. In the African setting, energy and livelihoods security are indeed inseparable. This paper argues economic, social, and environmental benefits of modern bioenergy can be realized through a strategy that centres on smallholder production and processing schemes and pursuit of a livelihood approach to energy development. Such a scheme opens up new domestic markets, generates new cash incomes, improves social wellbeing, enhances new technology adoption, and lays the ground for rural economic transformation and sustainable land use. The paper concludes by underlining the vital importance of considering sound property rights and strategic planning of sustainable development as tools for sustainable energy and livelihoods security.
