Slow Science in Development: Ensuring principled ecological auditing for the Smart Earth era in Hong Kong's Northern Metropolis

By HUI Chun Sing

• Presented at HKU Landscape's Public Review 2022.

Abstract: The HKSAR Government announced The Northern Metropolis Development Strategy in the 2021 Policy Address, increasing already significant pressures on and around wetland habitats of international importance. To enable faster, more efficient development, the Policy Address suggested undertaking a comprehensive review of the Environmental Impact Assessment (EIA) process. Under that mandate in February 2022, the Environmental Protection Department (EPD) proposed a Centralized Environmental Database (CED) that would significantly alter Hong Kong’s EIA process, especially its Ecological Impact Assessment (EcoIA). Such a database must take into account significant ecological and institutional challenges or else risk following dangerous and unsustainable trends in Smart City (or “Smart Earth”) development. This thesis: Identifies strategic points of intervention in the EcoIA process that will enhance development decision-making; Proposes a new framework of ecological auditing following scientific principles for optimising the EIA process; and Outlines the required time and expertise to conduct EcoIA and surveys its challenges, especially regarding the current/future deployment of Smart City (or “Smart Earth”) technologies. To do this, this thesis uses a comprehensive Gantt chart to organize a review of scientific ecological studies and past development projects in Hong Kong that predate the Northern Metropolis but are nonetheless central to its development and future sustainability. The HKSAR Government’s four main proposals for “optimizing” the EIA process include: (1) introducing a Centralised Environmental Database (CED); (2) optimising the EIA process completion time to around 18 months for typical projects and around 24 months for major or complicated projects; (3) standardising the requirements of ecological baseline surveys, covering the methods, frequencies, and durations required for conducting the surveys for different types of ecological systems; and (4) conducting EIA studies in parallel with the detailed design of development projects. The Government’s four proposals will directly impact the effectiveness and quality of EcoIA due to the inherent complexity and uncertainty of ecological knowledge handled in the existing deliberative process. This thesis supports a new ecological auditing framework (i.e., a principled systematic follow-up process) that builds trust among stakeholders, recognises the importance of transparency as a process (especially when threatened by increasing technological innovation), and ensures EIA is not reduced to a pro forma process chasing to secure development permits. The ecological auditing process can be a key tool for enhancing the scientific merit, accountability and comprehensiveness of the EIA process and directing the Northern Metropolis Strategy towards more sustainable means and ends.

Producing peatland: Landscape strategies for reorienting the capital and habitus of peatland's scientific production in the United Kingdom

By LO Wai Ching

• Presented at HKU Landscape's Public Review 2021.

Abstract: Peatland benefits society and nature in diverse ways, including serving as ecologically important habitat, productive farmland, and an immense carbon sink. Global policy trends promoting carbon markets risk peatland management being reduced to a commercial practice, marginalizing both the current emphasis on ecological benefits and the authority of existing peatland management groups. This thesis in landscape architecture proposes a socio-technical system explicitly targeting reductive practices that have led to poor land management and significant environmental degradation. Using a hypothetical pilot site in East Anglia, United Kingdom, its design strategies produce peatland focusing on (a) ecological, (b) hydrological, and/or (c) alternative financial benefits while strategically organizing these approaches' varying implementation complexity, time investment, and uncertainty. Importantly, although natural forces shape peatland over geological timescales, the scope, function, and meaning of peatland is socially constructed. Technical peatland management practices and their entwined social networks and knowledge domains are also highly context-specific, as demonstrated by comparing UK management regimes with those in Europe, Russia, North America, and Indonesia. This thesis asserts that peatland production must be simultaneously socially plural and steered by rigorous ecological science, especially given broader trends neoliberalizing the production of science in applied ecology. The design strategies explicitly preference techniques promoting the authority of disadvantaged stakeholder groups in the decision-making, implementation and technologically diverse monitoring and maintenance processes of peatland production. Landscape architects, with unique capacity to leverage the social and political economy producing these landscapes, can help bridge the ecological science of peatland management with our mainstream planning institutions.

Scientists out of their habitat: Coordinating knowledge production and action for complex landscapes in China's Ecological Redline Policy

By YAU Hoi Ying Ariel

Abstract: Ecological conservation redlines (“redlines”) are a set of recent policy initiatives under China’s Eco-Civilisation development approach that employs the concept of ecosystem services (ES) to delineate conservation priorities. Through studying a networked group of landscape ecologists’ approaches to redline delineation across China and mainland Southeast Asia, this thesis applies human geography and landscape architecture design methods to propose interventions in China’s current process of redline delineation that foreground the importance of collaboration between scientists and communities. In 2018, a group of landscape ecologists from Xishuangbanna Tropical Botanical Garden (XTBG), a top-tier research institution under the Chinese Academy of Sciences, developed a standardised framework of ecosystem assessments to inform land-use planning using predictive software, such as InVEST and MaxEnt, to delineate redlines for Shanghai municipality. These scientists later applied their framework for urban Shanghai to the entire mainland Southeast Asia, comprising both urban and sensitive rural ecologies. While not without differences, these landscape ecologists generally argued that redlines must be supplemented by additional planning measures to reflect broader biodiversity priorities. However, the delineation process they followed in Shanghai yielded a significantly reduced area of ES due to planners leading the stakeholder negotiation process. Indeed, academics in political ecology have criticised redlines as rendering conservation a primarily technical process that may further marginalise rural populations. Landscape architecture, with its focus on human-nature relationships, has the greatest capacity from within the design and planning disciplines to mediate between natural science and planning and to champion landscape ecologists’ recommendations on supplementing the redlines with sensitivity to social and environmental heterogeneity. To better equip landscape architects for coordinating the necessary expertise, this thesis applies social geographers Barnaud and Antona’s 2014 framework on the social construction of ES to China’s redline policy and process (1) to decipher why landscape ecologists and political ecologists diverge in their conservation priorities and approaches and (2) to explore what knowledge production processes may yield more appropriate conservation actions. Ten papers by landscape ecologists and political ecologists from or in collaboration with XTBG were analysed both qualitatively and spatially in GIS to identify divergences in these geographers’ and scientists’ preanalytic assumptions regarding ES. Scenario-building was then used as a tool to construct and reveal important interdependencies across scientists’ and communities’ conceptions of ES as necessary steps toward collective actions. Practical and redistributable tools such as interview questions and data collection sheets were designed as learning platforms. Ultimately, this thesis illustrates how narrow understandings of ES from landscape ecology reduce local actors’ capacities to supplement the redlines. Rural village planning must happen on a smaller but supplementary scale to China’s nationwide redline delineation process. The findings in this thesis serve as a primer for landscape architects who desire both to improve the institution of rural planning and to promote conservation with a more nuanced conception of ecosystem services in China and similar landscapes across Southeast Asia.

Green belt, grey belt? Non-zoned approaches to landscape evaluation and management in Hong Kong

By LI Man Hei Bernice

• Student Award, Hong Kong Institute of Landscape Architects (2018).
• Presented at HKU Landscape's Public Review 2017.

Abstract: Hong Kong's existing Country Parks, “green belts”, and a multitude of conservation-related zones conserve the territory's natural landscapes and resources. However, these designations are often weakly defined and susceptible to ever-increasing development pressures. By examining six sample sites representative of the Hong Kong's diverse threats to conservation, the work challenges zone-based planning and evaluation systems and suggests new methods of land categorization to increase the resiliency and manageability of Hong Kong's valuable natural areas. Using contested development plans for North Lantau Island as design test site, a more flexible yet less ambiguous approach is proposed to evaluate ecologically sensitive landscapes. This thesis extends landscape ecology's large-scale landscape gradient model, as an alternative to zone- or patch-based models, to small-scale sites by incorporating four aphysical value metrics: Conservation value; ecological value; redevelopment susceptibility; and manageability of the site. Two landscape management programs are proposed: 1) A productive landscape which encourages social and economic growth that is mutually benefiting the environment and villagers; and 2) a conservation landscape which conserves and restores the ecological legacies and its intactness. Both programs view rural landscapes as dynamic systems. Such a gradient approach can allow or facilitate the negotiation of social and ecological values across urban and natural areas.

An Environmental rationale: Strategies to reconcile the graduated sovereignty of northern China's eco-modernization programs

By AU YOUNG Chung Yan Samantha

• Presented at HKU Landscape's Public Review 2018.

Abstract: From 1980 to 2010, the Chinese government introduced a series of large-scale environmental programs across northwestern China, including Three-North Shelterbelt Program, Suspended Village Migration, 1236 Yellow River Irrigation Program, Natural Forest Protection Program, Sloping Land Conversion Program, and Converting Pastures to Grasslands Program. Focusing on the Ningxia Hui Autonomous Region, this thesis uses Emily Yeh's (2009) deployment of Ong's (2000) concept of “graduated sovereignty”, which theorizes the different modes of governing segments of the population, how these groups relate to global markets, and the different mixes of legal compromises and controls tailored to the requirements of special environmental zones. Overlapping histories and complex interactions amongst these eco-modernization programs have yielded diverse spaces of environmental governance. This thesis constructs a series of scenarios for the millions of refugees from these programs, tracing the overlaps and frictions of often coexisting programs that were defined as primarily either conservation- or economically oriented. Only through recognizing the heterogeneity of outcomes across these diverse landscapes can we find better ways to “green” northwestern China.

Catalyzing uncertainty and ecological risk: An Environmental archive for readying Hong Kong's plural ontologies

By Francisco CEVALLOS BARRAGAN

• Presented at HKU Landscape's Public Review 2020.

Abstract: Today, with a global environmental emergency alongside political battles for democracy and human rights, new strategies are needed to articulate trust and promote democratic environmentalist values, especially in contested regions. Contemporary society presents extreme discontents underpinned by ecological risk and an environment threatened by increasingly unchallenged dominant voices. Hong Kong’s environmental decision-making occurs within a laissez-faire economic system best described as neoliberalism with Chinese characteristics. Critical analysis of Hong Kong’s environmental governance system shows high relevance of advocacy groups, a lack of public participation, corporate pressure, weak institutions necessary for articulating various knowledges, and inadequate evaluation of the cumulative effects of environmental contamination. Following arguments across Hong Kong’s legal, health, information technology, and environmental sectors for the implementation of an archives law, this thesis proposes creating an Independent Environmental Archives Agency (IEAA) capable of collecting and representing evidence of cumulative impact, supporting process-oriented environmental governance, and “salvaging” (Choy, “Ecologies of Comparison”, 2011) scientific uncertainty for more sustainable development. Through a requirement of including the ontological perspectives of eight stakeholder groups with distinct yet closely aligned sustainability practices, this agency both effectively guarantees inclusion of diverse perspectives while also filtering knowledge and facilitating dialogue that privilege environmental uncertainty, longer-term objectives, and intergenerational equity. Examples of stakeholders include a director of corporate sustainability, an indigenous community leader, a Special Rapporteur to Hong Kong, a civil servant, an environmental activist, an environmental manager, and a developer-employed architect. Each stakeholder poses to the IEAA questions formed from distinct socio-political and disciplinary backgrounds (e.g., training in environmental law or corporate sustainability, degrees in social sciences or ecology, certificates in sustainable community governance), along with those backgrounds’ attendant biases and assumptions. A species-based approach helps further focus the selection of evidence and design of monitoring programs. The IEAA’s capacity for collecting, filtering and returning “data” from the archive on cumulative impact is improved as projects, assessments, and, most importantly, stakeholder queries are entered into and help strengthen its archive.

Making an environmental authority: Development, negotiation and the technical production of agricultural land under Hong Kong New Agriculture Policy

By CHONG Yan Suen Ceas

• Selected for HKU Landscape's Public Review 2019.

Abstract: The Hong Kong government unveiled the New Agriculture Policy in its 2016 Policy Address to promote the modernization and sustainable development of local agriculture. While questionable land deals and land-banking are prevalent at agriculture and wetland sites across Hong Kong's New Territories, the construction of the Agricultural Park (Agri-Park), proposed on active agricultural land at Tsiu Keng near Sheung Shui and Fanling, and its supporting infrastructure is controversial among various stakeholders for its technocratic planning and poor transparency. Using the complex developmental and ecological legacies of Hong Kong, this thesis designs a series of scenarios for the future of the Agri-Park that question our definitions of productivity and efficiency, biodiversity, land use categorisation and conversion, technical expertise and technology transfer, and legal implications of ownership versus stewardship. Rather than purely deconstructing the land development process, this work negotiates futures that recognise the productive tensions in the government's conservation mandates that allow it to make principled decisions in the face of powerful financial and development interests. The design proposes alternative ways to articulate the Agri-Park's objectives and wields existing ecological and developments metrics, such as risk and efficiency, to shift the development debate from physical planning to a broader, negotiated space for all stakeholders.
