Aiding multi-level decision-making processes for climate change mitigation and adaptation

Progress towards climate change aware regional sustainable development is affected by actions at multiple spatial scales and governance levels and equally impacts actions at these scales. Many authors and policy practitioners consider therefore that decisions over policy, mitigation strategies and capacity for adaptation to climate change require construction and coordination over multiple levels of governance to arrive at acceptable local, regional and global management strategies. However, how such processes of coordination and decision-aiding can occur and be maintained and improved over time is a major challenge in need of investigation. We take on this challenge by proposing research-supported methods of aiding multi-level decision-making processes in this context. Four example regionally focussed multi-level case studies from diverse socio-political contexts are outlined—estuarine management in Australia’s Lower Hawkesbury, flood and drought management in Bulgaria’s Upper Iskar Basin, climate policy integration in Spain’s Comunidad Valenciana and food security in Bangladesh’s Faridpur District—from which insights are drawn. Our discussion focuses on exploring these insights including: (1) the possible advantages of informal research-supported processes and specifically those that provide individual arenas of participation for different levels of stakeholders; (2) the complexity of organisation processes required for aiding multi-level decision-making processes; and (3) to what extent progress towards integrated regional policies for climate change aware sustainable development can be achieved through research-supported processes. We finish with a speculative section that provides ideas and directions for future research.

Governance objectives and instruments,ecosystem management and biodiversity conservation: the Chianti case study

The complex relationships between governance processes, ecosystem management and biodiversity conservation are receiving growing attention by the scientific community. The scope of research in this field is generally that of identifying main governance factors leading to success or failure in the sustainable management of ecosystems and biodiversity conservation, so to develop appropriate sectoral and intersectoral policies fostering sustainable use of natural resources. In this paper, a methodological approach is first presented and then applied to analyse the impacts of agriculture and rural policies on agro-ecosystem services and biodiversity conservation in the central hills of Tuscany, the Chianti area. This approach is focusing in particular on governance objectives and instruments used in the management of ecosystem services. A share-farming system based on multifunctional agriculture ruled Chianti until World War II. Then, after the abandonment of rural areas by share-farmers, governance objectives and ecosystem management were oriented towards the production of commodities such as wine and olive oil almost ignoring the provision of public goods such as soil erosion and water run-off control and biodiversity conservation. In order to achieve a more sustainable ecosystems management in Chianti, there is the need to develop a multifaceted governance strategy to reward appropriately the supplying of environmental goods and services by farmers.     

Water use in arid rural systems and the integration of water and agricultural policies in Europe: the case of Andarax river basin

Water is a precious resource in arid rural areas with irrigated agriculture. Nonetheless, water and agricultural policies in Europe show different management scopes and objectives, usually translated in divergent drivers of rural change. This paper has a double aim: to propose a specific method for quantitative biophysical analysis of water use in rural systems with the multi-scale integrated analysis of societal and ecosystem metabolism approach and to show the usefulness of this method for the assessment of the integration of water and agricultural policies. The river basin scale is chosen, since it is the socioecological unit for water management established in the water framework directive 2000/60/CE. A multi-scale water use accounting is provided for a Mediterranean river basin in Andalusia, integrating water cycle, ecosystems and social levels. Particularly focusing on agricultural production, a relevant set of indicators is proposed in order to analyze and compare different metabolic patterns. Finally, the integration of water and agricultural planning is assessed in terms of external (biophysical) and internal (economic, institutional) constraints of the new water-use patterns generated by the scenarios posed in these policies. While on a European level water policy is ambitious in terms of ecological conservation, the lack of integration within the common agricultural policy and the entanglement of multiple scales of political and economic organization of local ruralities blur its priority in a rather slow transition to a new water culture.     

An agent-based model of groundwater over-exploitation in the Upper Guadiana, Spain

Irrigated agriculture is a main user of groundwater. Achieving a sustainable use of groundwater will often require agricultural land-use changes such as shifting to entirely different kinds of crops and/or technologies. Enhanced understanding of land-use change is hence required for developing policies for a sustainable water future. We use an agent-based model to investigate the history of irrigated agriculture in the Upper Guadiana Basin, Spain, in order to learn about the influence of farmers’ characteristics on land-use change and associated groundwater over-use. A shift from vineyards and cereals to horticultural crops would provide a possibility for higher income with less water use. Such a shift cannot be observed historically. The model results suggest that risk aversion and path dependency are insufficient to explain this observation, and the organisational set-up of farms limiting the maximum labour force needs to be considered as additional explanatory factor. Furthermore, it is shown that different types of farms existing in the UGB can be expected to exhibit distinct responses to drivers of land-use change such as agricultural policies. It is concluded that a sound understanding of the social system making use of a resource is required to solve problems of resource over-use. This article demonstrates that agent-based models can be useful tools to enhance such an understanding even in situations of scarce and uncertain data that are often encountered when dealing with resource-use problems.     

Creating a “values” chain for sustainable development in developing nations: where Maslow meets Porter

This paper serves to establish an appropriate framework for prioritizing policy related to sustainable development by combining elements of Maslow’s hierarchy of needs theory with Porter’s value chain theory. An appropriate balance of social sustainability, economic sustainability, and environmental sustainability is defined so that policy makers may be provided some direction in regard to appropriate and socially just resource priorities. The model that forms the basis for this framework is then tested through hierarchal regression analysis using data from 45 developing countries. Using these results, the values chain framework has been refined to consider that self-actualization and sustainable development are one and the same and that the satisfaction of society’s physiological needs through the prioritization of policies related to environmental sustainability is the principle motivator for moving on to the attainment of higher-order needs such as increased levels of sustainable development.     

Sustainable agricultural attitudes and behaviors: a gender analysis of Iranian farmers

The purpose of this paper is to compare the attitudes of male and female rice growers towards environmental sustainability and identify the constructs that will influence their attitudes and behaviors. A survey methodology with systematic sampling techniques was used to select 181 households in four villages’ of Kazeroon, Iran. Results indicated that women farmers’ attitudes were more positive toward sustainability. A model was developed to explain farmers’ attitudes and behavior toward environmental sustainability. Finally, the determinants of sustainable agriculture attitudes and behavior are discussed.

Management of catchments for the protection of water resources: drawing on the New York City watershed experience

Primary purposes for catchment management are to establish a cost-effective allocation and use of its water resources and to most effectively apply measures to protect the quantity and quality of the water produced by the catchment. For the latter purpose, diffuse sources of contamination are the greatest difficulty. Diffuse (or non-point source) water pollution poses challenges for public policy and requires innovative management approaches. Solutions ultimately require behavioural change and a broad societal response, and must be flexible and adaptive to stochastic catchment conditions and to long-term trends. Internationally, new models of governance for difficult land and water resource management problems are developing. This paper reviews the characteristics of ‘wicked’ environmental management problems and the specific policy challenges posed by diffuse water pollution. A framework for action is derived and compared to the activities and outcomes of water protection in the New York City watershed. Successes to date in this case indicate that because land management and diffuse sources of pollution have a local basis, protection of water at source necessitates the fostering of local instruments for an adaptive and twin-track strategy of applied research and stakeholder deliberation, supported by multi-level partnerships and an enabling regulatory environment. Although long running, evidence from this case alone is insufficient to establish whether potential trade-offs between water protection and the economic vitality of catchment communities can be fully resolved.     

Farmers’ perception of sustainable agriculture and its determinants: a case study in Kahramanmaras province of Turkey

The primary purpose of this study was to assess in quantitative terms farmers’ perceptions of sustainable agriculture and to determine how those are influenced by different socio-economic characteristics and information-seeking behavior of the farmers. The study was conducted in Kahramanmaras province of Turkey and comprised a stratified sample of 208 farmers from four districts of the province. The farmers rated each of the 21 selected sustainable agricultural practices for importance on a 5-point scale, and the total of these ratings formed the sustainable agriculture perception index. The index score was calculated for each farmer and was treated as the dependent variable in the stepwise regression analysis procedure. The independent variables were such socio-economic characteristics as the farming system, the total and irrigated area of the farm, membership of a cooperative society and participation in village administration, and age, education, and income of the farmer; components of information-seeking behavior included use of the mass media (newspapers, radio, and television), use of the Internet, travel, and participation in farming events. The results of the study showed that the higher the socio-economic status (more frequent contact with extension services, higher education, ownership of land, etc.) and the greater the access to information, the greater the perceived importance of sustainable agricultural practices. It is concluded that if policy-makers and extension organizations concentrate on these factors, they are more likely to succeed in making farmers more favorably disposed toward sustainable agriculture.     

The ‘New Water Culture’ on the Web: an issue network analysis

In this article, we analyse how the Internet is used to bring visibility to water affairs. We focus on the way different organisations exploit the Web in order to participate in the debates about water policy in Spain and to define the topics concerned. To do this, we have drawn up an issue network articulated around an alternative and sustainable water policy called ‘New Water Culture’. We examine the composition of this web structure, its hyperlinking styles, key nodes and political trajectories. The outcomes indicate that the ‘New Water Culture’ has become a main frame in Spanish environmental policy. Supported both by governmental and non-governmental players, the ‘New Water Culture’ struggles between two opposing trends: its expulsion from the public sphere and efforts to open it up to scrutiny from political outsiders.     

Strategic environmental assessment application for sustainable transport-related air quality policies: a case study in Hanoi City,Vietnam

Recognition has grown among policy-makers that early in the decision-making process, there is a need for an environmental assessment of the effects of the policy, plan, and program (PPP) and their alternatives. Strategic environmental assessment (SEA) is widely recognized as a supporting tool that systematically integrates environmental aspects into strategic decision-making processes, thereby contributing to sustainable development. In this study, SEA was applied for an integrated assessment of environmental, social, and economic impacts of a wide range of scenarios for transport-related air quality policies to help decision-makers in identifying the most sustainable scenario with the purpose of reducing carbon monoxide (CO) concentrations from transport emissions in Hanoi City, Vietnam. In conducting SEA process, the urban air dispersion model MUAIR was used as a quantitative tool in prediction of CO concentrations. To evaluate the predicted impacts of scenarios, the SEA objectives concerning sustainability and the corresponding sustainable indicators were identified. Based on the likely significant predicted impacts on landscape, biodiversity, and health benefits, mitigation measures were proposed. These included planning in infrastructure development and implementation of public education campaign. The results of predicted and evaluated impacts of scenarios as well as proposed mitigation measures were taken into account for supporting sound decision-making that is consistent with the principles of sustainable development. Considering sustainable impacts of the scenarios, the SEA result clearly indicates that a combination of policy for public transport development and policy for installation of oxidation catalytic converter for motorcycles is the most sustainable scenario for reducing CO concentrations from transport emissions.     

Urbanization and sustainability: challenges and strategies for sustainable urban development in Bangladesh

Like other developing countries, urbanization in Bangladesh is a growing phenomenon, which is steady in nature but fretfully affects urban sustainability in the wake of lacking in good governance. Despite urban authorities are concerned about this issue, they often fail to address the problems due to the fact of uncontrollable and unpredictable rural to urban migration, and negligence of urban poor’s sustainable living and access to basic services. Virtually the rural poverty problem has been transposed to urban areas, particularly in Dhaka City, Bangladesh. Inadequacy of infrastructural services, basic amenities and environmental goods; environmental degradation; traffic jam and accidents; violence and socioeconomic insecurity are the major challenges which are created through rapid urbanization. This paper provides a general understanding of urbanization in Bangladesh and tries to embrace related sustainability issues and challenges hindrance to sustainable urban development in Dhaka city. In addition, it presents a brief case study of water supply in Dhaka city which introduces an issue of ‘system hijack’. The paper concludes providing some strategies that might be helpful to the policy makers in formulating development policies for sustainable urban services.     

Groundwater market and its implications on water resources and agriculture in the southern peri-urban interface,Chennai, India

This paper describes the informal groundwater market existing in the urban–peri-urban interface of Chennai. The private water tanker suppliers and packaged water industries utilize the land and water resources of the peri-urban villages. Thus, the groundwater sources in peri-urban areas play a significant role in meeting the growing urban demand. The villages that are experiencing the groundwater market are highly influenced by the urbanization and its related activities, due to their proximity to the city. The transfer of groundwater from the peri-urban villages not only deprives the peri-urban areas of their water rights but also leads to environmental damage. Agriculture declined in the water marketed villages in the range of 20–95 per cent during 1990–2007. The pre-monsoon and post-monsoon groundwater level fluctuation varied from 2–6 m to 0–5 m, respectively, during 1971–2007. The declining trend of the groundwater table and agriculture is highly significant in the water marketing villages. Moreover, the present groundwater quality is also in a susceptible state due to over extraction. Hence, strengthening the legal and institutional framework to ensure an equitable access to water for both urban and peri-urban areas is urgently required. This paper also describes the characteristics of the groundwater transfer, quantification of the marketed water, the role of the existing regulatory framework, and the institutional mechanisms. Many stakeholder’s meeting and focus group discussions have been conducted in the villages under study for understanding the socio-economic implications of the water market. The study ultimately emphasized a sustainable groundwater extraction/market which will safeguard the interests of the peri-urban and urban communities.     

Environmental goods collection and children’s schooling: evidence from Kenya

This paper presents an empirical study of schooling attendance and collection of environmental resources using cross-sectional data from Kiambu District of Kenya. Because the decision to collect environmental resources and attend school is jointly determined, we used a bivariate probit method to model the decisions. In addition, we corrected for the possible endogeneity of resource-collection work in the school attendance equation by using instrumental variable probit estimation. One of the key findings is that being involved in resource collection reduces the likelihood of a child attending school. The result supports the hypothesis of a negative relationship between children working to collect resources and the likelihood that they will attend school. The results further show that a child’s mother’s involvement in resource collection increases school attendance. In addition, although there is no school attendance discrimination against girls, they are overburdened by resource-collection work. The study recommends immediate policy interventions focusing on the provision of public amenities, such as water and fuelwood.     

The challenge of groundwater governance: case studies from Spain and Australia

This paper examines the relevance to groundwater management of Ostrom’s design principles for managing common property resources. Experience in four case studies of groundwater management in the Murray Darling Basin in Australia and the Upper Guadiana Basin in Spain suggests that while Ostrom’s design principles are relevant, sustainable groundwater management depends on the effective collaboration between government authorities and water users. A flexible and adaptive management approach is required, with collaboration between scientists, policy makers, water suppliers, and water users. Key management challenges include agreeing on a sustainable level of extraction, and establishing effective coordination and collaboration, and monitoring and control systems. Further case studies of groundwater management and their synthesis could make a useful contribution to the transition towards sustainable groundwater management regimes.     

Women NGOs and rural women empowerment activities in the Niger Delta, Nigeria

The study attempted to document beneficiaries’ perceptions on the contributions of Women NGOs (WNGOs) to the socio-economic empowerment of rural women in Akwa Ibom State, Nigeria. The specific objectives of the study included: an assessment of WNGOs contributions to improvements’ in beneficiaries’ socio-economic activities and constraints affecting beneficiaries’ participation in WNGOs activities. An attempt was also made to determine the existence of a significant relationship between the pre and post-participation income of WNGOs beneficiaries. A sample size of 240 respondents from 48 Local Women Groups (LWGs), which are affiliated to three active WNGOs in four states of the Niger Delta were utilized for the study. Findings revealed that WNGOs cater for a broad spectrum of rural women. WNGOs were revealed to affect beneficiaries’ socio-economic statuses through increased income generation, health awareness and acquisition of food processing skills. Constraints affecting beneficiaries’ participation in WNGOs activities include: inadequate credit facilities, and poor utilization of credit advances, resulting in poor loan repayment levels. A direct relationship was also revealed to exist between increased beneficiary exposures to WNGOs credit facilities and increased beneficiary income. It is believed that WNGOs are capable of more effective inputs into human and community development activities. Recommendations are proffered in this respect.

Perspectives and limitations of indicators in water management

This paper addresses the issue of indicators for water management by considering why we need them, what the characteristics of a good indicator should be, how they can add value to policy and decision-making, and what are their limitations. There are a vast quantity of data available on water in Europe from which a range of basic trend indicators has been derived. Most of these indicators address "what is happening?"-type questions. Some indicators go further and address "does it matter?" questions by assessing trends against prescribed standards and targets. There have been some interesting developments in indicators which help to understand the demand side of water management and to assess the relative efficiencies of resource usage in different socio-economic sectors. More effort is needed to bring together relevant social, economic and environmental information interactively to define indicators that address questions about the sustainability of water use and the contribution of the water environment to our overall quality of life. The development of indicators to date has concentrated on making the best use of available information. However, we now need to move from a position of "best available information" towards "best needed information". This will require better communication between information users and providers. It will also require a rethinking of exactly what our priority knowledge needs are to support policy-making and environmental management. This is essential if we are to obtain the best value from limited monitoring resources by eliminating the current redundancy in reporting requirements and refocusing programmes to deliver priority information needs.

Agroforestry as a sustainable landuse option in degraded tropical forests: a study from Bangladesh

The tropical deciduous forest in Bangladesh provides a substantial part of country’s forest and where the government has introduced participatory agroforestry landuse. This study examined management issues, financial viability, and environmental as well as social sustainability of this landuse system. The forest department allocated a plot of size 1.0 ha among the selected participants where they were allowed to practice agriculture as well as to plant tree species for 10 years. The financial indicators indicated that the landuse system was profitable and attractive [net present value (NPV) = US$ 17,710 and benefit-cost ratio (BCR) = 4.12]. It was also viable and suitable from the social and environmental stand points. The study concluded that under the present environmental and socio-economic scenario, this production system could be the best management tool that would earn money, stop forest degradation, and finally be a model of sustainable land management in an overpopulated country.     

The use of DPSIR framework to evaluate sustainability in coastal areas. Case study: Guanabara Bay basin,Rio de Janeiro,Brazil

The Guanabara Bay basin, SE Brazil, is shown as an experimental site to evaluate development and sustainability in coastal areas. We developed a Driver–Pressure–State–Impact–Response (DPSIR) framework in a practical context to integrate natural and socio-economic indicators. Sustainability reflects public policies towards the utilization of natural resources. Cost-benefit analysis (CBA) included in DPSIR evaluates losses and benefits resulting from such policies. CBA has some limitations due to the difficulty of valuating environmental goods and services. Instead of valuating them we propose to combine sustainability indicators and defensive expenditures for the implementation of public policies. This approach agrees with the environmental conservation paradigm implicit in sustainable development. It allows an estimation of the physical natural capital depreciation (PNCD), by using it to correct the gross domestic product (GDP) of the study area, and demonstrating the present non-sustainable characteristics of the current policies applied to the area.     

Uncertainty analysis in integrated assessment: the users’ perspective

Integrated Assessment (IA) models aim at providing information- and decision-support to complex problems. This paper argues that uncertainty analysis in IA models should be user-driven in order to strengthen science–policy interaction. We suggest an approach to uncertainty analysis that starts with investigating model users’ demands for uncertainty information. These demands are called “uncertainty information needs”. Identifying model users’ uncertainty information needs allows focusing the analysis on those uncertainties which users consider relevant and meaningful. As an illustrative example, we discuss the case of examining users’ uncertainty information needs in the SEAMLESS Integrated Framework (SEAMLESS-IF), an IA model chain for assessing and comparing alternative agricultural and environmental policy options. The most important user group of SEAMLESS-IF are policy experts at the European and national level. Uncertainty information needs of this user group were examined in an interactive process during the development of SEAMLESS-IF and by using a questionnaire. Results indicate that users’ information requirements differed from the uncertainty categories considered most relevant by model developers. In particular, policy experts called for addressing a broader set of uncertainty sources (e.g. model structure and technical model setup). The findings highlight that investigating users’ uncertainty information needs is an essential step towards creating confidence in an IA model and its outcomes. This alone, however, may not be sufficient for effectively implementing a user-oriented uncertainty analysis in such models. As the case study illustrates, it requires to include uncertainty analysis into user participation from the outset of the IA modelling process.
