The Zhanghe irrigation system (ZIS) is located in the Yangtze River Basin approximately 200 km west of Wuhan in Hubei Province. The reservoir was designed for multiple uses—irrigation, flood control, domestic water supply, industrial use, aquaculture, and hydropower. Over a period of more than 30 years a steadily increasing amount of water has been transferred from irrigation to other uses. Activities on the part of government, irrigation system managers, and farmers made this transfer possible with only modest decline in rice production. Most important factor was the steady increase in rice yields. The water pricing system provided an incentive for ZIS to reduce irrigation releases. With the steady decline in releases, farmers were forced to find ways to save water. Farmers improved existing ponds and built new ones to store water (improved infrastructure). Access to pond water on demand facilitated the adoption of alternate wetting and drying (technology) particularly in dry years. The establishment of volumetric pricing (price policy) and water user associations (institutions) may also have provided incentives for adoption of AWD, but more research is needed to establish their impact. These activities taken together can be seen as potentially complementary measures. Farmers received no direct compensation for the transfer of water, but recently farm taxes have been reduced or altogether abolished. Further reduction in water releases from the ZIS reservoir could adversely affect rice production in normal or dry years.

This study presents an automated method for detecting and measuring the apex head thickness of tomato plants, a critical phenotypic trait associated with plant health, fruit development, and yield forecasting. Due to the apex's sensitivity to physical contact, non-invasive monitoring is essential. This paper addresses the demand for automated, contactless systems among Dutch growers. Our approach integrates deep learning models (YOLO and Faster RCNN) with RGB-D camera imaging to enable accurate, scalable, and non-invasive measurement in greenhouse environments. A dataset of 600 RGB-D images captured in a controlled greenhouse, was fully preprocessed, annotated, and augmented for optimal training. Experimental results show that YOLOv8n achieved superior performance with a precision of 91.2 %, recall of 86.7 %, and an Intersection over Union (IoU) score of 89.4 %. Other models, such as YOLOv9t, YOLOv10n, YOLOv11n, and Faster RCNN, demonstrated lower precision scores of 83.6 %, 74.6 %, 75.4 %, and 78 %, respectively. Their IoU scores were also lower, indicating less reliable detection. This research establishes a robust, real-time method for precision agriculture through automated apex head thickness measurement.

This paper presents the results of an exercise to assess the effects of metaphors on knowledge management. Knowledge is an abstract phenomenon with no direct referent in the real world. To think and talk about knowledge we use conceptual metaphors. The exercise shows that these metaphors greatly influence the problems we identify related to knowledge in organizations and the type of knowledge management solutions we propose. The knowledge as water metaphor used in this exercise – which reflects the dominant way of thinking in Western knowledge management literature – leads to the thingification of knowledge, resulting in a discourse about ways to formalize, manage and control knowledge. This discourse primarily serves the interests of management. In contrast, the knowledge as love metaphor used in this exercise – which reflects more an Asian way of thinking about knowledge – shifts the discourse from the topic of knowledge as a thing to the underlying preconditions for good knowledge work. These conditions include the facilitation of knowledge professionals, the quality of the relationships in the organization, and the quality of the organizational culture. This discourse is aimed at humanizing the organization instead of formalizing it and is more in the interest of employees.

Strengthening sustainability in global supply chains requires producers, buyers, and nonprofit organizations to collaborate in transformative cross-sector partnerships (CSPs). However, the role played by nature in such partnerships has been left largely unattended in literature on CSPs. This article shows how strategizing nature helps CSPs reach their transformative potential. Strategizing nature entails the progressive revealing and reconciling of temporal tensions between “plants, profits, and people.” We show how a CSP took a parallel approach—recognizing the divergent temporalities of plants, people, and profits as interlaced and mutually determined—toward realizing their objective of implementing living wages in a sub-Saharan African country’s the tea industry, simultaneously driven by the revitalization of tea plantations. The promise of better quality tea leaves allowed partners to take a “leap of faith” and to tackle pressing issues before the market would follow. Our findings thus show the potential of CSPs in driving regenerative organizing.

With the increasing global population, urbanization, the current unsustainable and expansive agricultural practices would be expected to further elevate the risk of food and nutritional insecurity of the global population, which is recognized as a global threat for the 21st century. This paper reviews the demographic changes, urbanization, sustainability of the conventional agricultural systems, the environmental and resource implications and presents possible sustainable alternatives.

Refugees and internally displaced people who flee their homes due to environmental threats and far-going degradation which destroys their living conditions are not well-protected under international law. Refugee law focusses on political refugees. Establishing principals similar to the Responsibility to Protect (R2P) regime, (which is limited to genocide, war crimes, crimes against humanity and ethnic cleansing), could offer a solution for the lack of protection of environmental refugees. The obligation to establish this system could be based on the same obligation that forms the basis of the establishment of the R2P regime itself: the international obligation to prevent large scale suffering. This obligation corresponds with changed notions regarding state sovereignty and with the moral and legal obligations emanating from various human rights treaties. In first instance, according to R2P, the primary responsibility to take protective measures lies with the state itself. Secondly, the international community has a responsibility to assist. Lastly, the international community has a responsibility to respond duly and in a decisive manner when a state is unable or unwilling to provide protection for its citizens. The international community is equipped with a broad range of instruments under R2P that can be employed to protect environmental refugees. These instruments allow for custom-made solutions, which are absent in most traditional legal instruments

There has probably never been such an intense debate about the layout of the countryside as the one that is currently raging. There are serious concerns about the landscape, which is being rapidly transformed by urbanization and everything associated with this process, and not only in the Netherlands but also far beyond its borders. Everyone has something to say in this society-wide debate, from local to national governments, from environmental factions to the road-user's lobby, and from those who are professionally involved to concerned private parties. In many cases it is a battle between idealized images and economic models, between agricultural reality and urban park landscapes, between ecological concerns and mobility. This issue of OASE explores the potential significance of architectonic design for transformation processes on the regional scale. Besides considering the instruments that are available to the designer to fulfil this task, the authors also consider how the design can exercise a 'positive' influence on such processes. The various contributions shed light on the potential significance of territory in contemporary design practice and offer critical reflection on the topical discourse that has evolved over recent years.

Biodiversity, including entire habitats and ecosystems, is recognized to be of great social and economic value. Conserving biodiversity has therefore become a task of international NGO’s as well as grass-roots organisations. The ‘classical’ model of conservation has been characterised by creation of designated nature areas to allow biodiversity to recover from the effects of human activities. Typically, such areas prohibit entry other than through commercial ecotourism or necessary monitoring activities, but also often involve commodification nature. This classical conservation model has been criticized for limiting valuation of nature to its commercial worth and for being insensitive to local communities. Simultaneously, ‘new conservation’ approaches have emerged. Propagating openness of conservation approaches, ‘new conservation’ has counteracted the calls for strict measures of biodiversity protection as the only means of protecting biodiversity. In turn, the ’new conservation’ was criticised for being inadequate in protecting those species that are not instrumental for human welfare. The aim of this article is to inquire whether sustainable future for non-humans can be achieved based on commodification of nature and/or upon open approaches to conservation. It is argued that while economic development does not necessarily lead to greater environmental protection, strict regulation combined with economic interests can be effective. Thus, economic approaches by mainstream conservation institutions cannot be easily dismissed. However, ‘new conservation’ can also be useful in opening up alternatives, such as care-based and spiritual approaches to valuation of nature. Complementary to market-based approaches to conservation, alternative ontologies of the human development as empathic beings embedded in intimate ethical relations with non-humans are proposed. https://www.linkedin.com/in/helenkopnina/

This open access book states that the endemic societal faultlines of our times are deeply intertwined and that they confront us with challenges affecting the security and sustainability of our societies. It states that new ways of inhabiting and cultivating our planet are needed to keep it healthy for future generations. This requires a fundamental shift from the current anthropocentric and economic growth-oriented social contract to a more ecocentric and regenerative natural social contract. The author posits that in a natural social contract, society cannot rely on the market or state alone for solutions to grand societal challenges, nor leave them to individual responsibility. Rather, these problems need to be solved through transformative social-ecological innovation (TSEI), which involves systemic changes that affect sustainability, health and justice. The TSEI framework presented in this book helps to diagnose and advance innovation and change across sectors and disciplines, and at different levels of governance. It identifies intervention points and helps formulate sustainable solutions for policymakers, administrators, concerned citizens and professionals in moving towards a more just and equitable society.
