Residents’ Attitudes Towards Tourism in a Globally Important Agricultural Heritage Systems Pilot Site: a Case Study in China

Abstract

Globally Important Agricultural Heritage Systems (GIAHS) is a wide program to promote the conservation and adaptive management of such systems and their associated landscapes, biodiversity, knowledge systems and cultures. Rice-Fish Systems (RFS) in Longxian village of China, as a traditional agricultural system, was selected as one of the five pilot sites of GIAHS in 2005. Researchers have paid more attention to the dynamic conservation and adaptive management of RFS because it is under severe threats from global development challenges. Tourism is suggested to be brought into the RFS conservation program as an alternative industry. This paper presents a comparative study of residents in three types of farm household in Longxian, seeking attitudes to the RFS conservation and tourism development and ways in which such information may guide future strategies. Results show residents, belonging to the household type in which most family members are abroad, have the most positive attitudes to RFS conservation and tourism development; while residents, as other household type in which less than 50% of family members are abroad, are the least sensitive group in these three household types, due to the motivation of moving abroad weakening their enthusiasm to participate in the local activities. Implications are discussed in the context of how resident attitudes will affect the future management of GIAHS conservation and tourism development, and then measures are put forward to foster tourism cooperation and multistakeholders process establishment.

Impacts of climate change in rapidly urbanizing region – a case study in Hangzhou (China)

Climate change is expected to be a major driving force of landscape in the coming decades. It will have a multitude of potential impacts that vary in intensity and effect according to region and sector. In the context of global warming, the climate of China has changed significantly in the recent 100 years. The reason for climate change in China is mainly due to irrational land use caused by human activities, which chiefly results in the rapid industrialization and urbanization process. Based on an assessment model, this research represents a picture of the impacts of climate change in six districts of Hangzhou region. The aim of this paper is to conclude, on the one hand, some of Hangzhou sensitivities in relation to the primary effects of climate change. On the other hand, a reflection is made on a methodology to formulate preconditions on a scientific basis for further research by design of integrated adaptation options for the future spatial developments in function to upgrade Hangzhou resilience in relation to climate change challenges.     

Evaluating farmers’ likely participation in a payment programme for water quality protection in the UK uplands

Maintaining drinking water quality is essential to water companies and their customers, and agricultural non-point source pollution is a major cause of water quality degradation. In this paper, we examine the potential use of payments financed by a water company as incentives for farmers to adjust their agricultural land management practices in order to protect water quality. We use a choice experiment (CE) to measure farmers’ minimum willingness to accept (WTA) requirements to adjust agricultural land management practices in Nidderdale and the Washburn valley (Yorkshire, UK) under a potential local payment for ecosystem services (PES) programme. Latent class analysis of farmers’ CE responses was used to quantify the size and spread of farmers’ preferences and minimum WTA values for compensation payments, and to investigate potential drivers of preference variation. Analysis suggested that the emphasis on sheep or cattle/dairy production within mixed farming businesses in this area provides a partial explanation for the considerable observed heterogeneity in preferences and minimum WTA requirements for participation in a potential PES programme.     

Sustainable development in a natural resource rich economy: the case of Chile in 1985–2004

Searching for practical means to assessing economic growth’s sustainability, we extend a standard theoretical model to calculate “true” income measures for Chile, during the 1985–2004 period, and use estimates of natural capital depreciation to obtain genuine national saving measures. We found that, for the period, Chile’s economic growth was sustainable, even when approximately 2.5% of the income recorded by national accounts corresponded to depreciation of natural resources plus costs of atmospheric pollution. This performance can be partially explained by policies implemented to force fiscal responsibility and to assure wise public investment and expending during a natural resource driven growth. This evidence reinforces recent findings contradicting the natural resource curse, and the indirect negative effect of resource abundance over growth that would operate through the quality of institutions.     

Conservation agriculture in Ecuador’s highlands: a discrete choice experiment

Conservation agriculture has successfully spread in a number of developing country contexts, resulting in both positive production and environmental impacts. However, there are ongoing questions about the appropriateness of conservation agriculture for small-scale farming as poor farmers tend to be risk averse, typically lack access to credit, and may have planning horizons associated with heavily discounted future benefits. This study investigates farmer attitudes toward how a hypothetical set of conservation agriculture production practices will affect yield, labor use, erosion, and cost in two communities of Bolivar province, Ecuador, through the implementation of a discrete choice experiment. Results show producers are most concerned with future yields, planting labor, and overall costs. While off-farm erosion impacts are of concern, producers only placed small values on these impacts. Results provide support for conservation agriculture outreach to highlight practices that increase long-run production and reduce the time and technical skills associated with planting.     

Rice–wheat cropping cycle in Punjab: a comparative analysis of sustainability status in different irrigation systems

There is a general contention among scholars that first, wheat–paddy cropping pattern is largely responsible for declining ground water table in Punjab and secondly, that the wheat–paddy cropping system is becoming unsustainable over time as the yield levels of these two major crops are stagnating. However, the existing evidences do not throw adequate insight into the stage of groundwater depletion during which the wheat–paddy cycle becomes unsustainable. The paper strengthens the existing empirical base of sustainability status of this cropping cycle in Punjab. A comparison of irrigation systems in terms of both trends in yield and stability for wheat and paddy has been attempted to arrive at a holistic appraisal of sustainability aspects of crop specialization in Punjab. It is observed that the canal dependent irrigation system has performed better as compared to the overexploited groundwater irrigation system in terms of most of the parameters used in the study.

Krypton-85 in the atmosphere 1950–1977: a data review

For over 20 years the radioactive noble gas ⁸⁵Kr, the product of nuclear industry, has been released to the environment mainly from nuclear fuel reprocessing plants. Owing to its relatively long half-life $\text{T(}\text{1}\text{2}\text{= 10.76}\text{y}\text{)}$ and the absence of other appreciable sinks, a cumulative buildup of ⁸⁵Kr in the atmosphere is observed. The mean ⁸⁵Kr surface air activity in the northern hemisphere has increased from about 20 dpm/mmol Kr in 1950 to about 750 dpm/mmol Kr in 1977. In recent years, a substantial slow-down of the ⁸⁵Kr emission rate to the atmosphere has been observed. The published data indicate rather good mixing of ⁸⁵Kr in the northern hemisphere, but a gradient is observed in the southern hemisphere due to the fact that all nuclear fuel reprocessing plants are situated in the northern hemisphere and due to poor mixing of the atmosphere in the meridional direction.This paper summarizes nearly all of the data on ⁸⁵Kr activity in the atmosphere published up to the middle of 1978. The spatio-temporal distribution of ⁸⁵Kr atmospheric activity is discussed. Some forecasts of future ⁸⁵Kr concentration in the atmosphere and its possible ecological consequences are also presented.     

Enchytraeus albidus (Enchytraeidae): a test organism in a standardised avoidance test? Effects of different chemical substances

Enchytraeids (Enchytraeus albidus) directly improve the pore structure of the soil and are indirectly involved in regulating the degradation of organic matter. Due to their behavior they are able to avoid unfavorable environmental conditions. Avoidance tests allow a first assessment of toxicity of a contaminated or spiked soil within 48 h, by using the reaction of the enchytraeids as measurement endpoint. In this period, the organisms can choose between the control soil and the test soil. In the tests reported here, enchytraeids were exposed to LUFA 2.2 soil spiked with the following set of toxic substances: copper chloride, zinc chloride, cadmium chloride, phenmedipham, benomyl, carbendazim, dimethoate, atrazine, pentachlorophenol, chlorpyriphos, lindane, TBTO, Linear Alkylbenzene Sulfonates (LAS) and boric acid. Different chemical concentrations were tested. EC50s ranged from 8 mg/kg (Carbendazim) to >1000 mg/kg (e.g. LAS). While the tested heavy metals showed clear dose-response relationships, the effect pattern differed considerably in the tests with organic chemicals, e.g. no avoidance behaviour was observed in LAS, even at very high doses. Here we proposed to standardize the Enchytraeid avoidance test in a way similar to what is currently done for the earthworm and collembolan avoidance tests by the International Standardisation Organisation (ISO).     

Interprovincial migration in China, 1985–2005: a gravity modeling approach

This paper tries to identify the characters that might affect interprovincial migrants’ decisions and examine how and why the influence of these characters changed over time individually and synthetically in China during 1985–2005. We have investigated six types of factors, namely, distance, population density, income, employment structure, house price, and migration stock. In addition, we apply the identified factors with a multiple stepwise regression model to a longitudinal dataset, which consists of interprovincial migration flows over the last two decades in China. It is found that different factors have disparate impacts on migration in China, and they can be decomposed into push force in origin area and pull force in destination area. Factors shaping China’s interprovincial migration have shifted from traditional factors such as distance to economic factors such as income and employment structure. This paper suggests that more attention should be paid to obtain detailed migration data with spatial information and develop applicable models for migration processes. Our analysis provides references for development planners and policymakers to develop sound population policies to achieve regional sustainable development in China.     

Is there a density compensation effect in plant communities of anthropogenic habitats?

The occurrence of density compensation effect (DCE) has been estimated in areas occupied by synanthropic communities in the Western Caucasus. The density of dominant plant species has been estimated from their coverage, and that of subordinate species, from their frequency in 0.5-m² squares within 15 (16)-m² plots, using natural and seminatural communities as a reference standard. The factual material has been analyzed by the method of numerical experiments. The results show that the transformation of natural habitats into anthropogenic ones has led to a decrease in the species diversity of plant communities, but without causing a widespread occurrence of DCE. It is hypothesized that relatively high average values of species frequency in low-diversity synanthropic communities are more likely accounted for by random rather than compensatory processes.     

Who is in the Lower Reaches, Who Suffers Disasters？ Take Minqin County, a Disappearing Oasis as a Case

Minqin Oasis is located in the lower reaches of the Shiyanghe River Basin, northeast of the Heixi Corridor, at the middle of the Silk Road. Because of the its existence, Badain Jaran Desert and Tengger Desert cannot converge and develop in the south. It has always been an important green barrier to guarantee the eco-security of Hexi Corridor and the Silk Road for thousands of years. But in recent decades, Minqin Oasis is becoming smaller and the desert is becoming larger. Many people, especially the governmental officials in the lower reaches think that the upper and middle reaches have robbed the lower reaches of water resources, and caused insufficient water usage and the deteriorated eco-environment, in the lower reaches, However, the governmental officials in the upper and middle reaches claim that the whole river basin should take the upper and middle reaches as the key regions to develop economy. To address the above argument, we analyze the reasons why Minqin Oasis is disappearing, and find that there are two main factors. One is the quick development of population and economy in the upper and middle reaches; the other is the rapid development of population and economy in the lower reaches. The two factors both have great effect on the water utilization for eco-environment in the lower reaches. So Minqin Oasis is disappearing not only because of the upper and middle reaches but also because of the growth of population and economy itself. The lower reaches should not completely blame the upper and middle reaches. The upper and middle reaches should also pay more attention to the eco-environment in the lower reaches. The whole river basin should develop a harmonious and sustainable relationship among the upper, middle and lower reaches.     

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

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

Training future experts in “biodiversity and ecosystem services”: a progress report

Biodiversity is essential for multiple aspects of human life and well-being, but many current assessments of the functioning of biodiversity and ecosystems, understanding of risks posed by environmental change and the best practice of their management of ecosystems are lacking a unified scientific and conceptual basis. Methods such as scenario analysis, and terms such as ecosystem services, are widely used, but their meaning is understood in many different ways depending on context, user needs and experience of researchers. In order to advance the conceptual basis for ecosystem analysis and management in a rapidly changing world, as well as the ability of young scientists to reflect upon these concepts, we have organised five 2-week-long summer schools in Peyresq, a remote village in the Southern French Alps. In total 173 participants have worked intensively with 69 experienced researchers and a team of conveners and tutors in order to discuss a broad range of views on topics on ecosystem analysis and functioning. Topics ranged from conditions of and threats to various ecosystems due to environmental change, models and scenarios for assessment, stakeholder perceptions and needs for information, to the social and economic contexts for biodiversity. We report our experience from these schools, present the training concept which has emerged from them and suggest lines of further development.

Chloride - a precursor in the formation of volatile organochlorines by forest plants?

Two plants, a fern (Athyrium filix-femina) and a moss (Polytrichum commune Hedw.), both commonly occurring in Northern Temperate forests, were exposed in a laboratory study to a solution of (36)Cl-chloride. The uptake of (36)Cl-chloride by the plants was investigated and the emission of volatile chlorine 36 by the plants was determined. Furthermore, speciation of the emitted volatile organochlorine compounds (VOCls) was investigated. For the fern and the moss a rapid uptake of (36)Cl-chloride was observed within a 1-h exposure period. The uptake rates for the fern and the moss, respectively, were 16 mug (36)Cl-chloride g(-1) fresh weight (FW) h(-1) and 3.0 mug (36)Cl-chloride g(-1) FW h(-1), respectively. The study also suggested that after uptake by the plants (36)Cl-chloride is incorporated into VOCls, which were emitted by the plants into the atmosphere. Speciation analysis of the VOCls revealed the emission of chloroform, tetrachloromethane and 1,1,1-trichloroethane.     

Rural change and multidimensional analysis of farm’s vulnerability: a case study in a protected area of semi-arid northern Nicaragua

This paper presents an empirical research in a protected area of northern Nicaragua, aimed at: (a) classifying predominant narratives surrounding present and future pathways of the local rural system, drivers of change, features of livelihoods’ vulnerability; (b) understanding current functioning of local metabolic patterns of rural systems by developing a typology of farms and (c) comparing types’ vulnerability to current drivers of change. To achieve these objectives, we integrated qualitative and quantitative analytical approaches. The different visions of rural spaces, which emerge from the analysis of the narratives, and the five types of farms, characterized by specific land-time budget and energy and monetary flows, suggest two emerging dynamics of local restructuration in protected areas: (1) a dominant land re-concentration process which is generating increasing inequality in access to resources and a progressive marginalization of the self-sufficient economy of landless and subsistence households; (2) an emergence of a paradigm of ‘environmentalization’ of rural spaces together with a valorization of small and medium-scale diversified economies. Moreover, the vulnerability assessment focuses on multidimensional features of types’ sensitivity to crisis, i.e. risk unacceptability, production instability, economic inefficiency, food and exosomatic energy dependency, as well as capacity to buffer and adapt to change, i.e. access to assets, including labour for men and women, social safety nets and degrees of economic diversification. The discussion highlights the occurrence of trade-off between the solutions adopted by farms within different development paths, suggesting the relevance of the proposed framework of analysis at the interface between science and policy.
