Using sustainability science to analyse social–ecological restoration in NE Japan after the great earthquake and tsunami of 2011

In the wake of the catastrophic earthquake and tsunami that devastated part of northeastern Japan in March 2011, proposals for reconstruction and rehabilitation are still subjects of debate. The claim by many climate scientists that large-scale extreme events can be expected in the future, with similar catastrophic effects in coastal areas, suggests the need for long-term planning that aims at building resilience, the ability for socio-ecological systems to withstand and recover quickly from natural disasters, and continue to develop. We hypothesize that ecosystems and socio-economic resilience will provide affected communities with flexible barriers against future disasters and greater protection in the long run than will hard/engineering solutions such as high seawalls aimed at ensuring only physical security. Building social/ecological resilience in the Tohoku region will increase general security and is anticipated also to contribute to an enhanced quality of life now and for generations to come. This paper argues that building resilience in the affected area requires a transformation to sustainable agriculture, forestry and fisheries and we describe how the links between satoyama and satoumi, traditional rural territorial and coastal landscapes in Japan, can contribute to this revitalization and to strengthening the relationship between local residents and the landscape in the affected communities. Decision makers at local, regional and national levels need to take a holistic approach based on sustainability science to understand the inter-relationships between these landscapes and ecosystems to develop a robust rebuilding plan for the affected communities. Moreover, this paper suggests that building resilient communities in Japan that demonstrate the strategic benefits of satoyama and satoumi linkages can be a model for building resilient rural and urban communities throughout the world.

Application of a tri-capital community resilience framework for assessing the social–ecological system sustainability of community-based forest management in the Philippines

This study proposes and empirically tests a framework that integrates the concepts of community resilience and social–ecological system (SES) resilience through community forestry case studies. The framework provides a possible approach for assessing community resilience based on the development and allocation of socio-cultural, economic, and natural capital of individual households within a given forest community. Furthermore, aspects of SES resilience and system dynamics are used to define the potential state thresholds of community resilience. This exploratory attempt to quantify community resilience, using the proposed framework, aims to advance understanding of the conceptual overlaps of SES and community resilience as applied to forestry management. We consider community forestry groups as SES examples in which the community is an important stakeholder in managing natural forest capital. We selected pioneer communities under the community-based forest management (CBFM) Program in the Philippines as our case studies. We found that, on average, CBFM group members demonstrated moderate levels of resilience according to their acquired levels of capital. Although economic capital remained the weakest capital, the CBFM program had a positive effect in increasing the socio-cultural and natural capital of an entire community.     

Evolution and frequency (1970–2007) of combined temperature–precipitation modes in the Spanish mountains and sensitivity of snow cover

Snow cover in Spanish mountains is crucial for ensuring water availability in spring and summer months, for the success of winter tourism or for the maintenance of biodiversity in mountain ecosystems. A changing climate may affect the volume of snow cover even in high mountains, where weather conditions are usually favorable for snow accumulation. In this paper, we aim to investigate the evolution (1970–2007) of combined precipitation–temperature modes in the Spanish mountains, and the sensitivity of the snowpack to their occurrence. The climatic database “Spain02” and snow thickness data for Spanish mountains were used for this purpose. Results showed that the frequency of dry-warm and wet-warm days has increased over time in all mountain ranges, while the frequency of the “cold” modes has decreased. The thickness of the snowpack in the Pyrenees has also decreased and its evolution is negatively correlated with the frequency of dry-warm days, and positively correlated with the frequency of dry-cold and wet-cold days. This work constitutes the first approach that relates the evolution of climatic conditions favorable or unfavorable for snow accumulation and the evolution of the snowpack in Spanish mountains.     

Sustainable place-making for sustainability science: the contested case of agri-food and urban–rural relations

The paper explores the concept of ‘sustainable place-making’ and its necessary relationships and opportunities with the emerging, broader and interdisciplinary field of sustainability science. This implies a reconsideration of the new and emerging interrelationships between economy, community and ecology as a basis for active place-making. The paper then examines the new dynamics of place-making with regard to the contested emergence of the bio-economy and the eco-economy, and the principles and place framings that lie behind these competing paradigms of spatial development. The reference point here is agri-food and urban–rural relations; and it is argued that research in these fields is in need of being contextualised critically and normatively within this dynamic, highly contested and place-making context. The analysis also holds important implications for a more critical and engaging sustainability science.

Marine biodiversity and sustainability of fishing resources in Brazil: a case study of the coast of Paraná state

The subtropical coastal zone of Paraná state in southern Brazil is only 80 km long yet environmentally diverse, with relatively pristine coastal landscapes and high marine and coastal biodiversity supporting important artisanal fishing grounds. However, this region began to change in the early 1970s. The development of industrial harbors, as well as unregulated tourism and urban settlement and pollution caused the loss of natural habitats. In addition, commercial shrimp trawlers began to operate in the adjacent shallow shelf areas. Biodiversity was seriously affected, and local fish stocks have decreased drastically in the last four decades. This article describes a long-term program to protect coastal habitats, recover marine biodiversity and diversify the economic base of fishing communities in order to guarantee fish stocks for future generations, hence preserving the social and cultural identities of these communities. Although it is difficult to change traditional fishing practices, fishing communities may exploit alternate components of the marine biological resources in order to achieve environmental, social and cultural sustainability in the long term.     

Development of an educational model for sustainability science: challenges in the Mind–Skills–Knowledge education at Ibaraki University

Modern society confronts multiple sustainability challenges, including population growth, resources limitations, and a deteriorating environment. As a response, sustainability science education plays a major role in developing human capacity to manage these issues. This paper proposes the concept of “sustainability science education across Mind–Skills–Knowledge” as well as the competencies to be acquired and its pedagogy. This paper evaluates the effectiveness of such an educational system and its method of implementation using the example of the Graduate Program on Sustainability Science (GPSS), which was started at Ibaraki University in 2009.     

Power and politics of social–ecological regime shifts in the Chilika lagoon,India and Tam Giang lagoon,Vietnam

Analyses of ecological regime shifts primarily focus on abrupt, long-term and significant changes that trigger fundamental reorganisation in ecosystem structure and function. There remains limited empirical work on the relationship between regime shifts and social inequities, power imbalances, and social and environmental injustices. Inadequate attention to this social context restricts our ability to predict and avert impending regime shifts, or to effectively navigate where thresholds have been crossed. In this paper, we offer an initial empirical assessment of politics and power in two coastal lagoons in India and Vietnam experiencing abrupt change. We adopt a realist view of power to: (1) assess the social relations structuring human–environment interactions in both lagoons; (2) characterise the dominant framings and narratives that influence if and how regime shifts are understood; (3) consider who wins and loses if and when regime shifts and other forms of rapid environmental change take place; and (4) reflect on the implications of power and politics for the governance of regime shifts in linked human–ocean settings.     

Extractable soil nutrient effects on feed quality traits of crop residues in the semiarid rainfed mixed crop–livestock farming systems of Southern India

In the mixed crop–livestock systems, while general relation among feed quality, productivity and soil nutrient management have been reported, information on the effects of extractable soil nutrients on crop residue (CR) feed quality traits is scarce (e.g. in semiarid regions of Karnataka, India). In view of the increasingly important role of CR as feed components, in these farming systems, generating such information is a relevant research issue for sustainable development. Here, we report the occurrence and strength of relationships among extractable nutrients in soils and CR feed quality traits, and the effects of improved nutrients input on feed availability and feed quality of CR. Soil samples were collected from farmers’ fields in the semiarid zone of Karnataka and analyzed for available phosphorus (P), potassium (K), sulphur (S), zinc (Zn) and boron (B) using standard laboratory methods. Soil test results were clustered as low, medium or high based on the level of nutrient concentration. Four major farming systems involving nine crops and 419 farms were selected for on-farm trials. Under every sample farm, a plot with farmer’s practice (control) and improved fertilizer inputs (combined application of nutrients found deficient by soil testing) were laid. Performance of crops was recorded. Samples were collected for CR feed quality trait analysis using Near Infrared Reflectance Spectroscopy. The result showed that for cereal and oil crops, extractable soil S was significantly negatively associated with anti-feed quality traits such as neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL) (P < 0.01), but significantly positively related to metabolizable energy (ME) and in vitro digestibility (P < 0.01). Extractable B and K levels were associated positively and significantly with NDF, ADF and ADL for oil crops and cereals. Crop level associations, for most crops, showed similar trend. Improved fertilizer inputs affected CR yield much more than it did the quality. It increased ME productivity (ME ha^?1) and thereof the potential milk yield ha^?1 by as high as 40 % over the control. Therefore, balanced nutrient inputs on crop land positively impact productivity of the livestock compartment of mixed crop–livestock farming system, and this knowledge can build on the currently perceived need and benefits of balanced nutrient replenishment in crop–livestock system.     

Community-led reforestation: cultivating the potential of virtuous cycles to confer resilience in disaster disrupted social–ecological systems

Human relationships with trees can result in widespread citizen-led reforestation projects that catalyze social–biological-reinforcing feedback loops and set in motion virtuous cycles that restore perturbed social–ecological systems. These virtuous cycles confer resilience in such systems that counterbalance the tendency for vicious cycles to be triggered by destructive behavior and neglect. Given this argument, we ask: how do we cultivate the potential for virtuous cycles to confer resilience in social–ecological systems? To answer this question, we review feedback mechanisms and identify virtuous cycles catalyzed via ecological restoration to highlight their importance to the resilience of social–ecological systems. We then conceptualize these cycles with a causal map (also known as a causal loop diagram) illustrating an example where restoration activities and civic ecology practices contributed to feedbacks and virtuous cycles. Following from this example, we discuss approaches for recognizing and investing in virtuous cycles that accompany social–ecological systems and outline approaches for managing such cycles.     

Changing patterns of the temperature–mortality association by time and location in the US,and implications for climate change

The shape of the non-linear relationship between temperature and mortality varies among cities with different climatic conditions. There has been little examination of how these curves change over space and time. We evaluated the short-term effects of hot and cold temperatures on daily mortality over six 7-year periods in 211 US cities, comprising over 42 million deaths. Cluster analysis was used to group the cities according to similar temperatures and relative humidity. Temperature–mortality functions were calculated using B-splines to model the heat effect (lag 0) and the cold effect on mortality (moving average lags 1–5). The functions were then combined through meta-smoothing and subsequently analyzed by meta-regression. We identified eight clusters. At lag 0, Cluster 5 (West Coast) had a RR of 1.14 (95% CI: 1.11,1.17) for temperatures of 27 °C vs 15.6 °C, and Cluster 6 (Gulf Coast) has a RR of 1.04 (95% CI: 1.03,1.05), suggesting that people are acclimated to their respective climates. Controlling for cluster effect in the multivariate-meta regression we found that across the US, the excess mortality from a 24-h temperature of 27 °C decreased over time from 10.6% to 0.9%. We found that the overall risk due to the heat effect is significantly affected by summer temperature mean and air condition usage, which could be a potential predictor in building climate-change scenarios.     

Perceptions and patterns of human–elephant conflict at Barjora block of Bankura district in West Bengal, India: insights for mitigation and management

Human–elephant conflict is an issue of great concern regarding the growing competition between people and wildlife for food and shelter throughout Asia and Africa. The situation the Asian elephant faces is much critical. According to IUCN (Big hopes for endangered Asian Elephants, News Release, Gland, 2006), one of the prime factors to the decline of elephant population in India is the increasing trend in human–elephant conflict. Barjora block of Bankura district in West Bengal is one of the severe conflict prone zones in West Bengal, where elephant raid in every year has now become an inevitable phenomenon. As a result, crop damage, infrastructural damages, disturbances of daily activities, occurrence of human death and injuries have no doubt annihilated and frustrated the social fabric of life. This paper is an empirical attempt to address various consequences of human–elephant encounters which have an adverse impact on social, economic as well as the cultural life of the people. Instead of pursuing some traditional mitigation techniques, we argued much on understanding peoples’ perception to explore some sustainable mitigation measures to ensure the interest of both human and elephant and also to safeguard ecological integrity.

The Empirical Analysis of the Impacts of Income Distribution Gap on Consumption Demand: Based on the Statistic Data of Chinese Urban Residents in 2000–2010

Abstract

This paper analyzes the impact of income distribution gap on consumption demand from a theoretical view, and draws the conclusion that there is an inverse relationship between income distribution gap and consumption demand. Then, the paper finds that the existing widening income distribution gap in China has a negative impact on consumption demand, but this is not the key factor for the insufficient consumption demand because of the low level of per capital income. At last, it suggests that governments should improve the income level of entire residents and adjust income distribution structure simultaneously.     

Globalization and natural resources: the expansion of the Spanish agrifood trade and its impact on water consumption, 1965–2010

Beginning in 1960, the Spanish agricultural sector underwent an intensive process of development, resulting in important structural changes, not only in the sector itself, but also in the relationship of the agrarian system to natural resources. These changes were closely related to the growth of per capita income and Spain’s increasing integration into international markets. In the last five decades, the volume of Spanish agricultural trade has increased strongly, with a concomitant increase in the consumption of domestic water resources, requiring the construction of water infrastructure for irrigation. This paper examines the impact on water use in Spain during a period of economic modernization and trade liberalization. More specifically, we are interested in obtaining virtual water trade flow trends and identifying the major drivers responsible for these trajectories, via a decomposition analysis. Our results point to a large increase in virtual water exports and imports, primarily driven by the scale effect, that is, by the growing integration into international markets. The composition effect and changes in water intensity entailed a moderation in water consumption.
