Biomimicry as a Valuable Design Tool for Climate Change Adaptation

As built environment professionals face more pressing and difficult issues related to climate change mitigation and adaptation, it can be useful to look at examples of how other living organisms or ecosystems have solved the same problems. This paper examines global climate change impacts on society and ecosystems, primarily caused by human activities and built environments. It explores how buildings can mitigate climate change drivers while adapting to ongoing challenges. Through interdisciplinary perspectives and case studies, it presents strategies for climate-resilient building design. Looking at plants or animals that are highly adaptable or survive extreme climates or climate change can provide insight into how buildings could or should work. Exploring the properties of ecosystems that enable their adaptability and resilience can also offer potential opportunities. Therefore, this chapter explores whether bio mimicry, where organisms or ecosystems are imitated in human design, can be an effective means of mitigating the causes of climate change for which the built environment is responsible, or adapting to the effects on climate change. Different bio mimicry designs are discussed and categorized, a case study and examples illustrate the advantages and disadvantages of each approach. In light of the findings of the study, it is argued that an ecosystem-mimicking model that exploits synergies between climate change mitigation and adaptation strategies can be useful for the long-term biomimetic response of the built environment to climate to change there are also presented theoretical justifications that support it. Key Words: Biomimicry, Climate Change, Adaptation.

Canadian climate data portals: A comparative analysis from a user perspective

Climate data portals are essential tools for climate change adaptation. This study analyses differences between two Canadian portals providing bias-adjusted CMIP6 simulations: Climate Data Canada and Portraits Climatiques. The study evaluates three core variables (daily maximum temperature, daily minimum temperature and precipitation) as well as assesses five case studies, taken from the agriculture, transport and health sectors, that relied on climate indicators available through the portals. The underlying datasets vary in multiple ways (bias-adjustment methodology, climate of reference, ensemble composition, emissions scenarios) and, in general, the climatology of variables and indicators tends to be statistically different between portals towards the end of the century. Differences are significantly reduced when comparing projected changes with respect to present climate conditions, highlighting the important role played by the dataset used as a reference for the bias-adjustment procedure. When considered from the point of view of practical applications, the discrepancies between the portals are generally, although not always, sufficiently small that they do not impact the resulting decisions. Finally, indicators based on a fixed threshold were found to be strongly influenced by the reference used for the bias adjustment.

A Systematic Literature Review on Climate Change Adaptation Planning for Archaeological Site Management and the Prevalence of Stakeholder Engagement

AbstractThis article presents a systematic literature review of publications from 2014 to 2021 using “archaeological site” and “climate change” as keywords, in addition to several terms representing forms of stakeholder engagement. Articles were thematically coded to explore trends at the intersection of climate change, archaeology, and local and Traditional stakeholders. Results show that nearly half of the selected publications did not include local and Traditional stakeholder engagement in studies related to climate adaptation planning for archaeological sites. Synthesis of the results with insights gained from other literature on decolonizing archaeology showed that potential reasons for this gap include (1) the academic publishing culture, (2) archaeology as a predominantly Western discipline, and (3) increasingly available tools for climate change adaptation planning for archaeological sites. This article calls on the academic community to consider holistic stewardship using a landscape approach and to use climate change adaptation planning to elevate local and Traditional stakeholder input and values.

The Acadian Forest of New Brunswick in the 21st century: what shifting heat and water balance imply for future stand dynamics and management

Climate change is altering the dynamics of New Brunswick’s forests. To mitigate the effects of climate change, it is crucial to account for future uncertainties in climate projections and natural disturbance trajectories when designing forestry practices. This paper presents the projected changes in key climatic drivers for New Brunswick’s forests, examines the impacts of climate change on forest stand dynamics, and reviews adaptive silviculture tools for climate change adaptation. By 2071–2100, a projected 4–6 °C increase in mean annual temperature will lead to a 39%–77% rise in growing degree-days and a reduction in summer atmospheric water balance by 48–79 mm across New Brunswick. Foresters should anticipate a doubling of annual area burned, the northward migration of spruce budworm ( Choristoneura fumiferana (Clemens)), and the introduction of novel insects and diseases. Forest simulation models project a severe decline in boreal tree species abundance, including a 50% decline in balsam fir ( Abies balsamea (L.) Mill) and black spruce ( Picea mariana (Mill.) Britton et al.), offset by an increase in temperate species, notably red maple ( Acer rubrum L.; +200%) and American beech ( Fagus grandifolia Ehrh; +135%). Forests in the highlands and lowlands ecoregions, with 40%–50% and 15%–30% spruce and balsam fir composition, respectively, are particularly vulnerable. To limit climate change effects on forest values, foresters must prioritize climate resiliency in their management plans. Strategies should ensure the steady provision of forest goods and services under changing climatic conditions. Forest thinning enhances stand productivity and resilience, while shelterwood and two-age harvest balances timber production with diversity. Clearcutting, despite drawbacks, establishes younger, more vigorous forests with higher carbon sequestration potential. Assisted migration offers promise in helping threatened tree species adapt. Climate change will have a significant impact on New Brunswick’s forests, leading to changes in key climatic drivers, increased risks of disturbances, and a shift toward more temperate tree species. However, there are existing adaptation strategies available. It is crucial to consider future uncertainties when designing and evaluating forestry practices, as this is essential for mitigating the effects of climate change on forest values and ensuring the continued provision of forest goods and services over time.

Review on mangrove restoration: Re-greening the sea coast

Mangroves are important coastal resources that can provide exceptional ecosystem benefits. Several of its ecosystem functions, including sediment buildup, carbon sequestration, and storm surge protection, are being recognized as practical tools for climate change adaptation and mitigation. Its unique capacity to endure extreme environmental circumstances makes them; in particular, the only viable option for ecosystem-based adaptation in exposed coastal locations. Mangroves are among the most severely damaged tropical ecosystems, and they are continuing to disappear as a result of increased human activity. Especially in the Asia-Pacific region, where they exist in the form of complex socio-ecological systems, mangroves remain heavily threatened due to numerous anthropogenic activities. Mangroves are under grave danger; hence it is imperative that prompt steps be taken to methodically conserve and restore their ecosystems. The Asia-Pacific region is the location of nearly half of the existing mangroves, scattered over some of the poorest and post-conflict states. Dependence on traditional sources of income and the recent trend of coastal development have had a negative impact on the region's mangrove sustainability. Lacks of supportive policies and mangrove conversion to non-forest uses has been further fueled by insufficient institutional intervention. Nevertheless, in recent years, participatory, multi stake holder-based approaches for mangrove conservation and/or restoration have gained immense popularity in the region of Asia pacific. Participatory management which exemplifies an ameliorative approach can also support sustainable development, community empowerment, and social inclusion. Despite its asserted superiority, a number of new sustainability challenges need to be carefully examined and reconciled due to conflicting results of earlier experiences.

Climate Change and Sustainable Rural Livelihoods: Constraints and Adaptation Strategies

In today’s era, one of the most important threat to existence of human in climate change. Climate change is damaging people’s lives today. The impacts of climate change on health are core consideration of both the UN Framework Convention on Climate Change (UNFCCC) and reports by the Intergovernmental Panel on Climate Change (IPCC). Climate change has created havoc for the sustainable rural livelihoods in developing countries. Rural households are most vulnerable to climate change because of dependency on climate related resources like agriculture, livestock, forests etc. resulting in less diversification of livelihoods which further increase their vulnerability. Although various sustainable livelihood practices are being used by rural households but due to various constraints, they are not fully effective. Adaptation to climate change requires adjustments at all levels. The communities which are suffering from the climate change have to increase their resilience towards climate change by adopting appropriate technologies while make proper use of their traditional knowledge. Indigenous knowledge is increasingly being used as a tool for climate change adaptation. Vulnerable communities have used indigenous practices to plan adaptation and disaster risk reduction activities. Furthermore, government is focussing for sustainable development and climate change adaptation by finding and administering alternative methods to deal with issues of poverty and environmental degradation in context of linkage between livelihood and the immediate environment of the people. Finally, there is great potential for current policies to be implemented strategically towards building true adaptive capacity for the rural communities. At last, adaptation to climate change requires adjustments and implementations at each level- be it community, national or international.

Constraints to Agricultural Productivity in South East Nigeria: Evidence from Small-Scale Farmers in Abakaliki Metropolis

Being a key component of Ebonyi State economy, revenue from its agricultural sector has been on the decline. Literature search show that issues of constraints to agricultural productivity in the State have not been sufficiently classified. This study fills this gap by ascertaining the impact of economic, social and environmental factors on agricultural productivity in Abakaliki metropolis. Based on structural change theory, primary data were generated with the aid of a well-structured questionnaire. Simple random sampling technique was used to select 20 villages while purposive sampling technique was applied in selecting 10 farmers making it a total of 200 participants. Three null hypotheses were tested using F-test from analysis of variance (ANOVA) and Welch tests. We found that economic, social and environmental factors significantly constrained agricultural productivity in Abakaliki Metropolis. We also found evidences that high cost of mechanised farming relative to manual labour and inadequate capital; land constraint and low level of education of farmers; as well as problem of pest and diseases and climatic changes were, respectively, two major economic, socio-economic and environmental constraints to agricultural productivity. This study therefore recommends government intervention in the area of irrigation, drought-resistant technologies, and floods controls as necessary tools for climate change adaptation as well as improved farm tools, pest control, and access to farm lands.

Ecosystem Services in the Context of Agroforestry—Results of a Survey among Agricultural Land Users in the Czech Republic

Agroforestry, the use of trees at the interface between agricultural and forestry systems, is a key component of the multifunctional European landscape, where it provides a whole range of ecosystem services. Its main potential lies in the provision of services including increasing economic yield in agriculture and providing anti-erosion measures. The main objective of this research is to assess the perception of the providing ecosystem services of woody plants growing in agroforestry by farmers as key land users in the Czech Republic. Different aspects influencing farmers’ subjective perceptions were identified, especially depending on conventional versus organic farming methods. Respondents’ views were mapped using a structured questionnaire, which allowed for independently assessing the importance of windbreaks. Respondents considered regulatory ecosystem services the most important ones, in particular reducing soil erosion and flood risk, or increasing the resilience of the landscape to drought. Respondents perceived the physical obstruction of trees during mechanical tillage and the tenancy relationship with the land as the most significant problem with the introduction of agroforestry systems. The aim of this study is to promote innovative approaches in the national agricultural strategy in agroforestry as one of the tools for climate change adaptation towards sustainable agricultural production.

Precommercial thinning increased diameter growth while maintaining mixedwood stands composition, 15 years after treatment

Precommercial thinning could be a valuable tool for climate change adaptation, as it can promote stand diversity while increasing productivity. Softwood and hardwood stands are usually thinned following different methods, and we lack recommendations for application in mixedwood stands. We evaluated the effects of precommercial thinning on the growth and composition of balsam fir ( Abies balsameaL.)–birch stands dominated by paper and yellow birch ( Betula papyrifera Marsh. and Betula alleghaniensis Britt.), comparing methods and production objectives (systematic release-softwood, systematic release-mixedwood, crop-tree release-mixedwood, and crop-tree release-hardwood) in Québec (Canada). Precommercial thinning increased tree-level and stand-level growth, especially for both birches. Compared to the non-thinned control, thinning increased tree diameter at breast height annual increments by 60%–107%, with similar results among modalities. Thinning changed initial stand composition, but mixedwood production plots composition was similar to that of the control 15 years after treatment. Promoting diversity is often perceived to be made at the expense of wood production. Our results suggest that we can obtain both increased growth and maintain diversity. Precommercial thinning is currently suggested as an adaptation tool that can foster drought resistance. Based on our study, we suggest it could serve another purpose in climate-adapted forest management, that is, maintaining diversity and thus increasing resilience to disturbances.

Becoming a ‘good producer’ in the agri-environmental project economy

Agri-environmental projects have been portrayed as tools for climate change adaptation and mitigation and to overcome processes of deforestation, soil erosion, issues of water availability, and biodiversity loss. This paper is concerned with the social organisation of knowledge around agri-environmental projects offered to farmers in the department of Caquetá in Colombia. Using Institutional Ethnography (IE), we start with the experiences and work practices of small farmers or campesinos to explore how these are coordinated with the work of other people also involved in the organisation of agri-environmental projects. We identified the ideological code of the ‘good producer’ and argue agri-environmental projects are part of the wider ‘project economy’; an institution that shapes campesinos’ practices. Our data shows that what is portrayed as solutions to achieve sustainable livestock, poverty reduction, and the halting of deforestation, end up eroding the trust and willingness to cooperate of those whose work is crucial to achieve the conservation goals these projects claim to promote. Our research contributes to the growing body of social studies about agrienvironmental systems and explains how such interventions reinforce neoliberal agendas that risk replicating modernising logics of productivity, accountability, and efficiency.

A trait-based typification of urban forests as nature-based solutions

Urban forests as nature-based solutions (UF-NBS) are important tools for climate change adaptation and sustainable development. However, achieving both effective and sustainable UF-NBS solutions requires diverse knowledge. This includes knowledge on UF-NBS implementation, on the assessment of their environmental impacts in diverse spatial contexts, and on their management for the long-term safeguarding of delivered benefits. A successful integration of such bodies of knowledge demands a systematic understanding of UF-NBS. To achieve such an understanding, this paper presents a conceptual UF-NBS model obtained through a semantic, trait-based modelling approach. This conceptual model is subsequently implemented as an extendible, re-usable and interoperable ontology. In so doing, a formal, trait-based vocabulary on UF-NBS is created, that allows expressing spatial, morphological, physical, functional, and institutional UF-NBS properties for their typification and a subsequent integration of further knowledge and data. Thereby, ways forward are opened for a more systematic UF-NBS impact assessment, management, and decision-making.

The Recharge Channels of the Sierra Nevada Range (Spain) and the Peruvian Andes as Ancient Nature-Based Solutions for the Ecological Transition

Nature-Based Solutions for Integrated Water Resources Management (NbS-IWRM) involve natural, or nature-mimicking, processes used to improve water availability in quantity and quality sustainably, reduce the risks of water-related disasters, enhance adaptation to climate change and increase both biodiversity and the social-ecological system’s resilience. United Nations and the European Commission promote their research as a cornerstone in the changeover to the Ecological Transition. In the Sierra Nevada range (Spain) and the Andean Cordillera, there is a paradigmatic and ancestral example of NbS-IWRM known as “careo channels” and “amunas”, respectively. They recharge slope aquifers in mountain areas and consist of an extensive network of channels that infiltrate the runoff water generated during the snow-thawing and rainy season into the upper parts of the slopes. The passage of water through the aquifers in the slope is used to regulate the water resources of the mountain areas and thus ensure the duration of water availability for the downstream local population and generate multiple ecosystem services. This form of water management is known as Water Sowing and Harvesting (WS&H). As shown in this work, it is a living example of a resilience and climate change adaptation tool that can be qualified as a nature-based solution.

Stakeholders’ Perceptions of Nature-Based Solutions for Hurricane Risk Reduction Policies in the Mexican Caribbean

Nature-based solutions (NbSs) have long recognized the value of coastal and marine ecosystem management and associated ecosystem services as useful tools for climate change mitigation (e.g., blue carbon) and adaptation (e.g., coastal protection against flooding and storm surges). However, NbSs remain poorly acknowledged and mostly absent from coastal planning for disaster risk reduction policies in the Caribbean, as well as from ex-post disaster reconstruction funds. With the increasing frequency and intensity of hurricanes in the region, NbSs are now more needed than ever. Taking Mexico as a representative case study for the wider Caribbean, we here seek to identify and analyze the barriers and opportunities perceived by relevant stakeholders for mainstreaming coastal-marine NbSs into coastal management and disaster risk reduction policies (e.g., mangroves as green infrastructure) to protect coastal societies and national economies against hurricanes. We conduct semi-structured, in-depth interviews with twenty stakeholders covering academic, governmental, tourism, NGO, coastal planning, and financial domains. Among the twenty-three identified barriers, governance, institutional, financial, and human-capacity aspects are the most dominant perceptions behind the current lack of NbS implementation. Future action for the policy integration of NbSs requires widespread political will and better quantification of both the provision of ecosystem services and their economic benefits under conventional markets.

Development of models for sustainable green mussel cultivation under climate change events

This research developed a green mussel cultivation model to assist sustainable production for farmers under climate change events. The model consists of 4 sub-models: mussel growth, phytoplankton population, the effect of seawater quality on mussel density, and the influence of atmospheric parameters on seawater quality. The integrated model was constructed by STELLA software and was calibrated with field observation data. The model was employed to simulate the impact of climate change on mussels based on the Intergovernmental Panel on Climate Change: The Fifth Assessment Report (IPCC AR5) projection. Results demonstrated that mussel production varied due to differences in the available phytoplankton, the initial mussel weight, the cultivation period, the air temperature, and the rainfall pattern. The model simulations showed that under the greater radiative forcing scenario (Representative Concentration Pathways: RCPs), higher rainfall and air temperatures resulted in salinity reduction and thermal stress on green mussels. Consequently, mussel production was forecasted to decline over time. The simulations also revealed that during extreme weather events, low mussel density, high aeration, and being far from freshwater discharge could avoid mass mussel mortality. Using the results of the developed model, an appropriate cultivation period can be forecasted. However, it depends on the site-specific climate pattern in each cultivation area. Results can be employed as a climate change adaptation tool for mussel farmers. Finally, the information can assist other researchers interested in sustainable mussel cultivation under extreme events.

Are climate finance subsidies equitably distributed among farmers? Assessing socio-demographics of solar irrigation in Nepal

Solar-powered irrigation pumps are a vital tool for both climate change adaptation and mitigation. Since most developing countries cannot fully utilize large-scale global funds for climate finance due to limited institutional capacities, small-scale solar irrigation pumps (SIPs) can provide a climate-resilient technological solution. We study the case of a subsidized SIP program in Nepal to understand who likely benefits from a small-scale climate finance program in a developing country setting. We analyze government data on profiles of farmers applying for SIPs and in-depth interviews with different actors along the SIP service chain. We find that vulnerable farmers (women, ethnic minorities, and poor farmers) were less likely than wealthier and non-minority farmers to have access to climate finance subsidies. Even though the government agency gave preference to women and ethnic minority farmers during beneficiary selection, an unrepresentative pool of applicants resulting from social and institutional barriers that prevented them from applying to the program led to an inequitable distribution of subsidized SIPs. The lack of a clear policy framework for allocating climate finance subsidies was a significant constraint. Lack of periodic updating of SIP prices and poor provision of after-sale services were also responsible for the inequitable distribution of subsidized SIPs. We recommend the involvement of local governments in soliciting applications from a wider pool of farmers, periodic revision of SIP prices to reflect market price, replacement of the current fixed subsidy scheme with a variable subsidy scheme, and mandatory provisions of after-sales services.

An Integrated Extreme Rainfall Modeling Tool (SDExtreme) for Climate Change Impacts and Adaptation

The estimation of the Intensity–Duration–Frequency (IDF) relation is often necessary for the planning and design of various hydraulic structures and design storms. It has been an increasingly greater challenge due to climate change conditions. This paper therefore proposes an integrated extreme rainfall modeling software package (SDExtreme) for constructing the IDF relations at a local site in the context of climate change. The proposed tool is based on a temporal downscaling method to describe the relationships between daily and sub-daily extreme precipitation using the scale-invariance General Extreme Value (GEV) distribution. In addition, SDExtreme provides a modified bootstrap technique to determine confidence intervals (CIs) of the estimated IDF curves for current and the future climate conditions. The feasibility and accuracy of SDExtreme were assessed using rainfall data available from the selected rain gauge stations in Quebec and Ontario provinces (Canada) and climate simulations under three different climate change scenarios provided by the Canadian Earth System Model (CanESM2) and the Canadian Regional Climate Model (CanRCM4).

Home gardening in sub‐Saharan Africa: A scoping review on practices and nutrition outcomes in rural Burkina Faso and Kenya

AbstractHome gardening is promoted as an adaptation strategy to ameliorate the increasing food insecurity from climate change impacts among subsistence farming families in rural sub‐Saharan Africa. Yet, the geographic distribution of home gardens, their setup, management, and the effects on nutrition outcomes have not been fully described. This scoping review aimed to map and synthesize recent evidence on home gardening for two exemplar countries: Burkina Faso and Kenya. Between June and August 2020, we searched, screened, and extracted evidence about home garden projects in both countries, following the PRISMA guidelines for scoping reviews. Peer‐reviewed scientific publications, and gray literature in English and French that reported about subsistence horticulture in rural settings of Burkina Faso or Kenya were included. The characteristics of the documents and the data pertaining to our research objectives were extracted into predefined spreadsheets. The data were synthesized in the form of a narrative review. Our search yielded 949 documents, of which 20 documents were included in the synthesis (Burkina Faso: 8, Kenya: 12). While the gardens varied in composition and size, the majority provided green leafy vegetables and indigenous horticultural crops. The challenges for successful home garden implementation comprised unfavorable climatic conditions, access to and affordability of inputs, water and land, and lack of know‐how. We identified trends for improved food security, diet quality, and nutritional status among the target populations. This scoping review found that there is limited evidence on home garden practices in rural Burkina Faso and Kenya. To enhance the sustainability of home gardens, research and resources should be invested in codesigning context‐specific home gardening projects. Pending rigorous impact evaluation, home gardens appear to be a promising tool for climate change adaptation while simultaneously improving food security and the nutritional situation among women and young children in these two exemplar countries of sub‐Saharan Africa.

Using PhenoCams to track crop phenology and explain the effects of different cropping systems on yield

CONTEXTCrop phenology integrates information of how environmental drivers and management practices affect plant performance and crop yield. However, little is known about the impact of cropping systems (CS) on crop phenology and how this relates to differences in yield. OBJECTIVESWe assessed the applicability of PhenoCams to track crop phenology, how four CS, i.e., organic vs. conventional farming with either intensive or conservation (no/reduced) tillage affect the phenology of a pea-barley mixture and winter wheat, how crop phenology is related to harvest characteristics, e.g., grain yield and total N uptake, and explains CS effects on these characteristics. METHODSWe used time-lapse cameras (PhenoCams) to track vegetation changes in the two crops and extracted the green chromatic coordinate (GCC) to estimate different phenological metrics, i.e., dates with major changes in GCC (PhenoTimePoints), the duration between those (PhenoPhases), and the rate of increasing or decreasing GCC (PhenoSlopes). We assessed how phenological metrics were affected by different CS, and related phenological metrics to harvest characteristics. RESULTS AND CONCLUSIONSCS significantly affected phenological metrics of both crops, with less pronounced effects in the unfertilized pea-barley mixture compared to the fertilized winter wheat, and stronger effects for early-season than for late-season PhenoTimePoints. For winter wheat, organic compared to conventional farming caused an initial growth lag (up to 7 days) and a shorter duration (approximately 10 days) of the period of stable GCC. Winter wheat in reduced/no-tillage systems showed a tendency of delayed phenology (up to 5 days) compared to intensive tillage. While phenological metrics explained harvest characteristics of winter wheat well, they were almost unrelated to those of pea-barley, most likely because pea-barley yields were similar among CS. For winter wheat, effects of CS on harvest characteristics could be well explained by phenological metrics (max. R2 = 0.9). Thus, we demonstrated that delayed phenology acted as an important factor causing lower yield in organic compared to conventional farming. SIGNIFICANCEPhenoCams are valuable tool for high-resolution temporal monitoring of crop phenology. As different CS have been proposed as a tool for climate change adaptation, we suggest that the effects of CS on crop phenology need to be considered as they may impact yield via changes in crop phenology, particularly in organic agriculture.
