We provide a rationale for the technique of revaluating the natural-resource potential which is built upon the natural crop
yield of Ukrainian lands obtained, with the observance of rotation cropping and by implementing the complex of mechanical
tillage operations without fertilizer application. An assessment is made of Ukraine’s natural-resource potential within the
context of three physical-geographical countries, four zones, three subzones, and 14 krais. 相似文献

The construction of a comprehensive observation platform for natural-resource elements would provide data support for studies of dynamic changes in various natural resources, and could serve the needs of natural-resource management and the construction of ecological civilization during a period of global change. As the second-largest inland river basin in NW China, the Heihe River Basin (HRB) lies in the central part of the Silk Road Economic Belt, consequently, pilot studies of resource management in the basin are urgently needed. This paper describes the construction of a comprehensive natural-resource elements observation network in the HRB to meet requirements for natural-resource management, based on natural-resource and Earth-system science. Based on current observations and research, thirteen observation stations were established in different river basins through integration with existing stations, reconstruction and upgrading, and new construction. The main types of land-surface resources in the HRB (grassland, forests, rivers, lakes, deserts, wetlands, and farmland) were included in the observation network constructed for the monitoring of natural-resource elements. Long-term, continuous, and stable observation can yield key data concerning coupling processes, trends of change, and rates of change in natural resources. This is of great significance in improving cognitive ability, scientific management, and strategic decision-making regarding natural resources in the HRB, and can provide a reference paradigm for the observation of and research into natural resources in other basins. 相似文献

Although 97% of U.S. farms are “family-owned,” little research examines how gender and sexual relationships – inherent in familial dynamics – influence farmers’ practices and livelihoods. Gender and sexual dynamics – shaped by race and class – affect who is considered a farmer, land management decisions, and access to resources like land, subsidies, and knowledge. We use feminist and queer lenses to illuminate how today’s agricultural gender and sexual relations are not “natural,” but when left uninterrogated are constructed in ways that harm women and queer farmers while limiting potential to develop sustainable practices. Women and queer farmers also resist, “re-orienting” gender and sexual relations in ways that expand possibilities for achieving food justice and ecological sustainability. We offer “relational agriculture” as a tool for making visible and re-orienting gender and sexual relations on farms. Relational agriculture brings sexuality into food justice and demonstrates the centrality of gender and sexuality to agricultural sustainability. 相似文献

The specific natural-geographical system of the Upper and Middle Amur basin, including the right-bank area (PRC) is investigated. The system is characterized by a single-type landscape and geological structure, and by mineral resources similar in composition. An analysis is made of the natural-resource potential, and the strategic directions of its economic utilization with due regard for the trans-boundary factor are predicted. 相似文献

黄河三角洲芦苇湿地生态修复效果评价研究 总被引：1，自引：0，他引：1
基于黄河三角洲芦苇湿地退化现状及所实施的生态修复工程,以正负参照系选取了4块不同修复年限的样地,从湿地生态系统的环境质量、结构与功能的角度构建了湿地修复效果评价指标体系,利用层次分析法确定各指标权重,利用模糊综合评价法对黄河三角洲盐渍化芦苇湿地的修复效果进行定量评价。结果表明:黄河三角洲芦苇湿地4年修复期的样地评价得分为4.01,2年修复期的样地评价得分为3.16,对应评价结果分别为"优"和"良"的等级。相比负向对照,修复区的水体指标和土壤指标参数显著改善,而植被生物量和密度与自然样地还有较大差距,说明生物群落的建立需要更长的时间;同时,湿地水资源管理是该区芦苇湿地生态修复工程的关键,应根据芦苇不同生长期的需水量,制定合理的抽灌制度,达到洗碱脱盐和植被建群的双重目的。 相似文献

Drawing on ethnographic case studies from Madagascar, this research shows that multiple marine conservation projects have institutionalized inequitable access to marine recourses along gendered lines. Despite discursive and institutional shifts toward more “collaborative” and “community-based” conservation programing, there is a deficiency of women’s nominal as well as effective participation in community management organizations. This research shows that conservation organizations’ focus on proximate drivers of marine resource use, or a politics of picking the “low-hanging fruit,” over ultimate drivers such as global commodity chains, places disproportionate emphasis on marine spatial enclosures and restricting specific, and gendered, harvest methods. To address gender bias concerning access to and control over natural resources, we must go beyond the rhetoric of “community involvement” to address gendered inequalities in conservation decision making, and whose interests are served by conservation projects. 相似文献

在“一带一路”倡议下,中国与土库曼斯坦的投资合作成为“中国—中亚—西亚经济走廊”建设的重要内容。土库曼斯坦油气资源丰富,已成为各国投资商的重要关注点。不过,该国较为封闭,相关数据资料相对匮乏。在此背景下,本文基于土库曼斯坦自然资源、经济、社会文化和投资管理等条件,借助熵权法对土库曼斯坦各州和直辖市的投资环境进行了综合评价。研究表明,自然资源是各州和直辖市投资环境演变的核心推动力量,同时投资管理特征和经济发展也发挥重要作用,社会文化特征的影响则不显著。因此,由于资源在空间上分布不均衡,土库曼斯坦各地区的投资环境也存在较大差异,从而导致油气资源不足的地区对投资管理形成较大依赖。总体来看,巴尔坎州和莱巴普州投资环境较好,而马雷、达沙古兹等地区仍有待提高。 相似文献

Spatial Heterogeneity of Russia in the Light of the Concept of a Green Economy: The Social Context 总被引：1，自引：0，他引：1
This paper presents the results of a comparative spatial analysis of the regions of the Russian Federation in the context of the concept of a green economy with the use of two quantitative factors that characterize the well-being of the population: the payroll fund and the total wage fund and own revenues of the regional budgets per capita. The key environmental and economic indicators used in this study are the indicators of eco-intensity for regional economic systems. They show the particular negative impact on the environment “produced” by the regional economy per unit of economic result. The following characteristics of the region’s socio-ecological system are considered: the volume of atmospheric pollutant emissions in terms of 1000 rubles of the regional payroll fund and in terms of 1000 rubles of own income to regional budgets. The study revealed a high degree of heterogeneity of Russia’s regions in socio-environmental characteristics. It is shown that not only does the population of many natural resource and industrial regions live in conditions of increased anthropogenic pressure (both total and specific), but it also is not provided with additional resources of “collective well-being” through its own budget income, in spite of the unfavorable ecological and natural conditions. It is concluded that carbon regulation aimed at developing a low-carbon economy should not focus on identical quantitative indicators for the whole country. 相似文献

CIVIL SOCIETY PARTICIPATION IN THE DECENTRALISATION OF BRAZIL'S WATER RESOURCES: ASSESSING PARTICIPATION IN THREE STATES 总被引：1，自引：0，他引：1

Decentralisation, the transfer of powers to a lower level of government, is thought to encourage more efficient and equitable management of natural resources. Participation of civil society organisations (CSOs) is considered critical to create positive outcomes of decentralisation. Here we examine aspects of civil society participation in decentralised management using the case of Brazil's water resources management. Several Brazilian states have enacted reforms mandating watershed committees in which the participation of civil society is either encouraged or required. However, actual participation of civil society is not yet well understood. To assess participation, we collected qualitative data on watershed districts in three Brazilian states (Bahia, Paraná and São Paulo). Our findings reaffirm the importance of the state in establishing a transparent legal framework to encourage participation and in defining “civil society”. The ability of civil society leaders to obtain and deploy local environmental knowledge, which frames environmental issues in new geographical scales, is useful to achieve the efficiency and efficacy objectives of decentralisation. However, by “upscaling” political activities beyond decentralisation's new territories, CSOs could make decentralisation irrelevant to local environmental issues. 相似文献

Abstract Fire, either natural or man-caused, has influenced the pattern of vegetation in numerous areas over the earth. Factors that contribute to potential damage to either the vegetation and/or environment are examined. Since the extent of damage varies, a fire can be destructive or useful. The use of “prescribed” fire in land management accomplishes several desired objectives, one of which is the perpetuation of certain fire-climax vegetation types, such as pines and some grasses. In those pine-forested areas where fire is regularly used in management, a related benefit is the reduction of hazardous natural fuels, which results in fewer catastrophic wildfires. Air pollution due to forest burning is also considered. 相似文献

The dynamics of social vulnerability are of key interest to many government agencies and departments. Identifying the geographic distribution of vulnerability within regions, and analysing how localised areas of social need change over time, is a key information requirement for decision-making, and the resultant allocation of resources. Typically, the delineation of areas for the determination of social vulnerability occurs using a combination of political and census boundaries. In many instances, the boundaries of these areas align to natural geographic features such as rivers or lakes. In other cases, a boundary is aligned to a man-made structure such as a road. The boundary may also be arbitrarily positioned based on some measure of distance and not align to any physical feature. In this research, we identify the various boundary types present in a political region. Using two measures of social vulnerability, we assess these boundaries as barriers to the continuity of social vulnerability. From our results, we identify motorways/highways and watercourses as potential barriers. We find no significant effects with lesser road structures suggesting there is no “wrong side of the street”. These results have implications for decision-makers and emphasise the need to recognise the “softness” of boundaries, and consider the relationships between areas, when allocating resources. 相似文献

边缘型旅游地的开发建设是中国旅游业转型升级时代面临的重要命题。随着区域经济一体化的推进和消费者消费理念的转变,一些边缘型旅游地开始逐渐成长为区域旅游发展的"潜力区",研究空间与研究意义日益凸显。以具有典型边缘性特征的宣城市为实证,从区位空间、旅游资源、旅游形象、旅游交通和旅游经济等角度剖析其多重边缘化特征,探讨边缘化形成的主要机制。地处省际交界区、地域特征典型性不足是边缘化形成的自然诱因,周边核心旅游地遮蔽效应显著是边缘化形成的空间致因,经济支撑能力薄弱是边缘化形成的经济制因,政策惠及偏少是边缘化形成的人为促因。边缘型旅游地应实施多元比附、突出个性差异、完善要素建设的发展路径。 相似文献

I argue that scientific disciplines are esteemed, supported, and patronized largely to the degree to which they are perceived as providing a “return” on invested societal resources. This “return” takes the form of scholarly products that help answer deep human questions or otherwise materially benefit members of the society whose resources they are. Such a view implies that disciplines exist in a “market” in which members compete for these limited resources by delivering products seen as valuable. In such a market, disciplinary relevance and survival are ultimately tied to decisions individual scholars practicing within the disciplines make about which research they pursue, the greater the perceived “return” the better for the long‐term health of the discipline. 相似文献
