Spatio-temporal evolution dynamic, effect and governance policy of construction land use in urban agglomeration: case study of Yangtze River Delta, China

The urban construction land change is the most obvious and complex spatial phenomenon in urban agglomerations which has attracted extensive attention of scholars in different fields. Yangtze River Delta Urban Agglomeration is the most mature urban agglomeration in China, a typical representative in both China and the world. This paper analyzes the evolution dynamic, effect and governance policy of urban construction land in Yangtze River Delta Urban Agglomeration 2011-2020 using a combination of BCG model, decoupling model and GIS tools. The findings are as follows. (1) There are large intercity differences in urban construction land in urban agglomerations, but the spatial heterogeneity is gradually decreasing. (2) The change trends and evolution patterns of urban construction land in urban agglomerations are increasingly diversified, with emergence of a variety of types such as rapid growth, slow growth, inverted U-shape, stars, cows, question and dogs. (3) The population growth, economic development and income improvement corresponding to the change of urban construction land in urban agglomerations have no desirable effect, with most cities in the expansive negative decoupling state. (4) The decoupling types show increasingly complex changes, in evolution, degeneration and unchanged states. Affected by economic transformation and the outbreak of COVID-19, an increasing number of cities are in strong negative decoupling and degeneration states, threatening the sustainable development of urban agglomerations. (5) Based on the division of urban agglomerations into three policy areas of Transformation Leading, Land Dependent, and Land Reduction, the response strategies for each are proposed, and a differentiated land use zoning management system is established.

Stuck between Mother Earth and a mother’s womb? On women, population policy and ecological sustainable development

This article considers how the metaphor of Mother Earth, for women, concerns a dual stance of both belonging and distance. The link between women, nature and Mother Earth is problematised by considering the possible, or contested, link between population growth and climate change, and the South African population policy specifically is considered as an example. Ecofeminism’s challenge to the perceived connection between women, motherhood and Earth, that is the ‘distance’ stance, is considered and a response to that is offered by reflecting on Mercy Oduyoye’s notion of mothering, which represents the ‘belonging’ stance. In this regard, an intercultural approach to the definition of motherhood is implied. It is ultimately indicated that for women to reclaim their own agency regarding a perceived responsibility towards nature, it is necessary to deconstruct and reconstruct ‘motherhood’ to free themselves from being stuck between Mother Earth and a mother’s womb. Contribution: This article makes a contribution to feminist studies at the intersection of gender roles and the climate crisis, as it relates to population growth and an intercultural definition of motherhood. It contributes to UN’s sustainable development agenda as it relates to both SDG 5 (gender equality) and SDG 13 (climate action).

Estimating Preferences for Wood Furniture in Terms of Sustainable Forest Management

The world’s forest area decreased to three point nine billion hectares in 2015, a net annual loss of 3.3 million hectares, and large-scale deforestation is occurring in the tropics. Furthermore, greenhouse gas emissions are increasing as forests are converted to other uses such as agricultural land. Against this backdrop, sustainable forest management is becoming increasingly important. This study attempts to quantify people’s general awareness and values concerning for on-line shopping habits (in this study, for wooden furniture) in terms of sustainable forest management in Japan by estimating the acceptable price premium or willingness of consumers to pay for wood-related products made using wood produced under sustainable forest management as the raw material. The study proceeds to quantify the awareness and values of consumers concerning sustainable forest management and conservation of forest environments. Consumers were found to have a certain willingness to pay for wooden furniture made from wood produced through sustainable forest management. As a consequence of this analysis, it was revealed that consumers place a high value on sustainable forest management and environmental conservation, and that they are willing to act on these values when purchasing wood-related products.

A Review and Categorization of Artificial Intelligence-Based Opportunities in Wildlife, Ocean and Land Conservation

The scholarly literature on the links between Artificial Intelligence and the United Nations’ Sustainable Development Goals is burgeoning as climate change and the biotic crisis leading to mass extinction of species are raising concerns across the globe. With a focus on Sustainable Development Goals 14 (Life below Water) and 15 (Life on Land), this paper explores the opportunities of Artificial Intelligence applications in various domains of wildlife, ocean and land conservation. For this purpose, we develop a conceptual framework on the basis of a comprehensive review of the literature and examples of Artificial Intelligence-based approaches to protect endangered species, monitor and predict animal behavior patterns, and track illegal or unsustainable wildlife trade. Our findings provide scholars, governments, environmental organizations, and entrepreneurs with a much-needed taxonomy and real-life examples of Artificial Intelligence opportunities for tackling the grand challenge of rapidly decreasing biological diversity, which has severe implications for global food security, nature, and humanity.

Assessment on Land-Water Resources Carrying Capacity of Countries in Central Asia from the Perspective of Self-Supplied Agricultural Products

Despite the declining hunger in Central Asia, food insecurity remains an important issue due to the dry climate. Taking Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan as examples, this study assesses their land-water resources carrying capacity in 1999, 2009, and 2018, on the premise that agricultural water and farmland are spatially matched based on the “buckets effect”, using the ecological footprint and water footprint methods. Results show the following: (1) the total farmland area in Central Asia is sufficient to achieve food self-sufficiency;the available farmland area is 2.45 times that of the farmland required for self-sufficiency in 1999, which decreased to 1.71 times in 2009, but slightly increased to 1.92 times in 2018. Specifically, Kazakhstan maintains a surplus of more than 15 × 106 ha in farmland, while the other 4 countries could not achieve self-sufficiency. (2) The water resources pressure rises;the available agricultural water resource (AAWR) in Central Asia is 3.07 times that of the water demand for agricultural irrigation (WDAI), and 3.06 times that of the water demand for irrigation and environmental purification (WDIEP) in 1999, which decreased to 1.69 times of WDAI and to 1.60 times of WDIEP in 2018. Tajikistan has the highest level of water surplus, followed by Kyrgyzstan and Kazakhstan. Turkmenistan and Uzbekistan do not have enough water to sustain agricultural production. (3) The trend of land-water resources carrying capacity declines in Central Asia. In 1999, 2009, and 2018, the land-water resources could support the population’s food demand in this region when only considering farmland matched with WDAI. However, the population carrying capacity deficit would emerge if we considered the matching farmland with WDIEP.

Microbial Biostimulants as Response to Modern Agriculture Needs: Composition, Role and Application of These Innovative Products.

An increasing need for a more sustainable agriculturally-productive system is required in order to preserve soil fertility and reduce soil biodiversity loss. Microbial biostimulants are innovative technologies able to ensure agricultural yield with high nutritional values, overcoming the negative effects derived from environmental changes. The aim of this review was to provide an overview on the research related to plant growth promoting microorganisms (PGPMs) used alone, in consortium, or in combination with organic matrices such as plant biostimulants (PBs). Moreover, the effectiveness and the role of microbial biostimulants as a biological tool to improve fruit quality and limit soil degradation is discussed. Finally, the increased use of these products requires the achievement of an accurate selection of beneficial microorganisms and consortia, and the ability to prepare for future agriculture challenges. Hence, the implementation of the microorganism positive list provided by EU (2019/1009), is desirable.
