Abstract

Purpose

In this paper, the authors show that ecological restoration potential through natural regeneration of degraded tropical rainforest is possible. This is significant because at present most of the tropical forest of the world, including of Bangladesh, are degraded.

Design/methodology/approach

Regeneration status of Chunati Wildlife Sanctuary (CWS) was assessed through stratified random sampling method using sample plots of 5 × 5 m in size covering 269 sample plots.

Findings

A total of 3,256 regenerating seedlings/saplings of 105 species belonging to 35 families were recorded from CWS. From regenerating tree species, maximum (37.83) family importance value (FIV) index was found for Euphorbiaceae followed by Myrtaceae (18.03). Maximum importance value index (IVI) was found for Aporosa wallichii (21.62) followed by Grewia nervosa (16.41). Distribution of seedlings into different height classes of regenerating tree species was also calculated.

Practical implications

Forest scientists are working to find out the best nature-based solution for ecological restoration of tropical rainforests to attain climate resilient ecosystem in a sustainable way. Tropical rain forest has huge plant diversity, and we find that ecological restoration is possible through natural regeneration from its rich soil seed bank. Natural regeneration is the best nature-based solution for sustainable management of the forest.

Social implications

The authors believe that the findings presented in our paper will appeal to the forest and environmental scientists. The findings will allow readers to understand degraded tropical hill forest ecosystem and its management strategy.

Originality/value

The authors believe that this manuscript will give a clear picture about degraded tropical hill forest ecosystem and its genetic composition, diversity and soil seed bank status to apply appropriate management strategy.

Abstract

Purpose

This paper aims to define and theoretically analyse the performance of modern methods investigated to speed up the recultivation process of degraded areas, and apply it into the mining basin, open pit mines, tailings and all other areas, which need environmental quality improvement.

Design/methodology/approach

This paper presents methods of conservation and substitution of natural resources for the purpose of faster land recultivation (reclamation) in degraded coal mine areas. Two types of methods have been developed: forest slope recultivation and agricultural recultivation of flat landfills. Indicators of positive changes include: changes in chemical properties of tailings, increase in biogenic properties and changes in biodiversity.

Findings

The research results show that the application of these methods, along with the holistic approach and adequate investment, can significantly contribute to the length of recovery process and accelerate it.

Research limitations/implications

Mining basin Kostolac is used as a model test. The results can be applied on all mining basin, open pits and any degraded area.

Originality/value

All results and conclusions were drawn, based on the original measurements and experiments. Stake holders, wanting to manage environmental quality after exploitation in mining basin, applying those methods, can find the value of this paper.

Abstract

Purpose

The purpose of this paper is to identify the importance of floodplains in preserving biodiversity, and call attention to alternative ways of managing floodplains in relation to probable scenarios of climate change.

Design/methodology/approach

In total, 20 water bodies on the floodplain at Flisa along the River Glomma (Hedmark County, Eastern Norway) were investigated with regards to crustacean zooplankton and water beetle species richness.

Findings

Both on a national and regional scale, the species diversity in the investigated water bodies was high. A total of 57 crustacean plankton and 77 water beetle species were recorded. Of these, ten and eight were new records of zooplankton and water beetle species in Hedmark County, respectively. Seven recorded water beetle species were specified in the 2010 Norwegian Red List of Species. Further, the localities on the Flisa floodplain are relatively unique with regard to the composition of species compared to other investigated localities in Hedmark County.

Social implications

Floodplains are intensively used and are considered as among the most threatened ecosystems in the world. More frequent and less predictable floods can be expected in the future due to climate change's influence. In some settings more frequent larger floods may work to re‐establish the connectivity, but larger floods might also result in demand for construction of more extensive flood mitigation measures.

Originality/value

The results from this case study underpin the high biodiversity of floodplains, an ecosystem infrequently examined in Norway. The results of this study are of importance regarding management and maintenance of ecosystem services (e.g. biodiversity and water retention) from floodplains.

Abstract

Purpose

Urban landscapes play a significant role in supporting municipal, ecological and social systems. Besides, valuable environmental services and urban green spaces provide social and psychological services, very important for the liveability of modern cities and the well-being of urban residents. It is clear that the area of green space in a city, the method of designing urban landscape and access to urban green space potentially affect the health, happiness, comfort, safety and security of urban dwellers. Urban landscape plays a significant role in providing habitats for wildlife, and an important vegetation type in doing this is species-rich herbaceous vegetation that provides pollen and nectar plus physical habitat for native fauna. Any factor that makes an impression on the urban landscape (such as climate change) will affect people’s lives directly or indirectly. There is a universal consensus that the temperature has increased in most of the world over the past century the investigation of climate change impacts on the urban landscape is the purpose of this study.

Findings

Understanding the process of climate change adaptation is necessary to design plant communities for use in public landscapes. Increased CO2 and air temperature in conjunction with the changing rainfall conditions, as the three important factors of climate change, potentially alter almost all world ecosystems. Climate change provides new opportunities, and in some cases, an obligate need to use non-native plant species in conjunction with native plant species, not only to reduce the side effects of climate change but also to increase the species diversity and aesthetic value in meadow-like naturalistic planting design.

Originality/value

The authors confirm that this work is original and has not been published elsewhere. In this paper, the authors report on the effects of climate change on urban landscape and suggest different kind of solutions to reduce the effects. The paper should be of interest to readers in the areas of landscape architecture, landscape ecologist, landscape planner, landscape managers and environmental designer.

Abstract

Purpose

This paper aims to present a general analysis and overview of forest biodiversity, emphasising the three main components (structure, composition, function) related to biodiversity. Following this theoretical consideration of forest biodiversity the current proposal of the European Environment Agency for biodiversity indicators is presented as a table with the application to forests identified and the direct/indirect nature of the indicator also indicated.

Design/methodology/approach

The biodiversity of forests is determined by a number of overall large‐scale factors that intimately affect the individual components of biodiversity. A more specific and direct measurement of forest biodiversity is presented with data assessed by the Fungib programme to provide a set of biodiversity indices that can be used to: create biodiversity baselines; compare sites; and follow biodiversity changes through time, all with the possibility of determining significance of change statistically. An example of data derived from a macrofungal survey is presented as an example of how this methodology can be adapted to many groups of organisms. Finally, a further example of using biodiversity quality data to understand changes in biodiversity is presented comparing butterfly biodiversity quality with nitrogen deposition.

Findings

This paper shows how an example of function (nitrogen deposition) has affected an element of composition (butterfly biodiversity). This has been made possible by the use of a rational sampling methodology (TRIM) used over a number of years. This metadata analysis of butterfly survey data shows clearly that changes in the butterfly biodiversity quality would have been missed if the normal approach of equating biodiversity with species richness had been adopted. In this example nitrogen‐sensitive species loss was compensated by nitrophilic species gain.

Originality/value

Such a methodology, therefore, has much to recommend it and it has been shown to be applicable to a wide range of organisms from bryophytes to beetles. For forest biodiversity monitoring the adoption of this kind of rationale will hopefully yield far greater information to the scientific community and policy makers for little extra effort.

Abstract

Purpose

The purpose of this paper is to give a general description and analysis of the key factors important for forest biodiversity, and to show the development of a strategy for choosing an indicator methodology for assessment of forest biodiversity. Different biodiversity indicator schemes (methodologies) have been developed recently and all should be capable of being adapted to the specific objectives of biodiversity assessment and to the forest types concerned.

Design/methodology/approach

A forest ecosystem comprises three main components: structure (e.g. physical characteristics); composition (e.g. number and population of species); and function (e.g. evapo‐transpiration) and it is upon these characteristics that forest biodiversity is based and determined. Forest ecosystems can therefore be characterised by key factors (parameters) which are important for the development of indicators and evaluation of biodiversity.

Findings

The key factors can be grouped or classified according to major ecosystem components and also according to spatial scale (national, regional, landscape and stand level). Selected indicators are the tools that can be used to assess the size/or level and quality of forest biodiversity.

Originality/value

Biodiversity key factors and indicators are crucial for studying and monitoring forest biodiversity.

Abstract

Purpose

The purpose of this paper is to show how corporate responsibility (CR) could be utilized to manage and develop individual, cultural, and biodiversity and turn them into business strategies.

Design/methodology/approach

Case studies of two multinational forest companies are used to demonstrate present and possible corporate values, words, and actions of diversity.

Findings

Forest companies tend to react on external pressure in diversity issues. They often take a confrontational or minimum legal compliance approach. Biodiversity, cultural diversity, and individual diversity form an intertwined hot topic all over the world.

Practical implications

For future prospects, forest companies should take initiative in diversity enhancement and become entrepreneurial, particularly as pulp and paper production is a declining industry and new business visions are needed. In cooperation with indigenous peoples, environmental organizations, governments, and other stakeholders forest companies could replace monocultural tree plantations with multicultural forest gardens, which provide many ecosystem services, natural products, and employment, and participate in large‐scale forest leasing for conservation. Multinational forest companies could also make better use of their diverse individual and cultural resources.

Originality/value

This is the first attempt to build a CR/diversity framework by studying different kinds of diversity issues through CR and by analyzing corporate values, words, and actions. Integrating diversity into CR helps companies to turn it into a business strategy.

Abstract

Purpose

The purpose of this paper is to develop a novel tenant mix model for shopping malls based on an analogy from ecological theories.

Design/methodology/approach

This study empirically investigates the tenant species‐area relationship and tenant species‐abundance distribution in shopping malls. In this study, the tests on species‐area relationship and species‐abundance distribution in shopping malls are derived from ecological theories. Empirical tests by a sample of 18 shopping malls for the species‐area relationship and of five malls for the species‐abundance distribution are carried out in Hong Kong

Findings

It shows that, in line with the findings of biogeography, the tenant species‐area relationship follows a power law of exponent of about 0.20. Furthermore, the species‐abundance distributions of the five large‐scale malls are found to be closely in track with a geometric distribution as commonly found in ecology. These results imply that tenant mix strategies are governed by two principles: the number of tenant species is related to the mall size; and the shop area allocation follows a geometric distribution.

Research limitations/implications

The study provides the first quantitative tenant mix model on the number of tenant species in a particular mall size, and on the tenant species abundance distribution pattern. These results provide far‐reaching implications for research and practice, including a quantitative benchmarking of tenant mix strategy and an optimal design of shopping malls.

Practical implications

The model is the first tenant mix model for practitioners to formulate quantitative tenant mix strategy, and evaluate the effects of tenant mix on the performance of a shopping mall.

Originality/value

It is the first quantitative model for tenant mix, and would open up a novel agenda for research on tenant mix strategies.

Abstract

Purpose

This paper aims to respond to recent calls by Jones (2014) and Jones and Solomon (Accounting, Auditing & Accountability Journal, 2013) for more studies on biodiversity accounting and reporting. In particular, this paper explores biodiversity reporting of the Murray-Darling Basin Authority (MDBA), an Australian public sector enterprise.

Design/methodology/approach

The paper uses content analysis of MDBA’s published annual reports over the period of 15 years (1998-2012). Archival data (from different government departments) are also used to prepare natural inventory model.

Findings

The paper finds that although specific species, such as flora and fauna, and habitats-related disclosures have increased over the time, such information still allows only a partial construction of an inventory of natural assets, using Jones’ (1996, 2003) model. However, unlike prior studies that find lack of data availability to be the main impediment for operationalising biodiversity accounting, the abundance of biodiversity data in Australia makes it comparatively easier to produce such a statement.

Research limitations/implications

Informed by the environmental stewardship framework, the results of this paper suggest that the disclosures made by MDBA are constrained potentially due to its use of traditional accounting mechanisms of reporting that only allow tradable items to be reported to stakeholders. An alternative reporting format would be more relevant to stakeholder groups who are more interested in information regarding quality and availability of water, and loss of biodiversity in the basin area rather than the financial performance of the MDBA.

Originality/value

Although there are a growing number of studies exploring biodiversity reporting in Australia, this paper is one of the earlier attempts to operationalise biodiversity (particularly habitats, flora and fauna) within the context of an Australian public sector enterprise.

Abstract

Purpose

The purpose of this paper is to present an approach aimed at facilitating nature conservation that builds on the ecological and social synergies that exist in traditionally managed landscapes in and around protected areas and integrates conservation and social goals to achieve a reduction in the levels of marginalization of indigenous and local communities while preventing ecosystem degradation and biodiversity loss.

Design/methodology/approach

Drawing on literature research and insights from political and historical ecology and systems theory, a framework was developed to aid the understanding of human‐environment interactions taking place in traditionally managed ecosystems and landscapes and to monitor the role that these interactions play in the maintenance of such systems.

Findings

Virtually all ecosystems and landscapes must be seen as coupled social‐ecological systems whose ability to respond to stresses and change derives from ecological and social characteristics, as well as from the link between these natural and human components. A variety of mechanisms by which indigenous and rural communities help anchor biodiversity and contribute to social‐ecological resilience were identified.

Originality/value

This paper challenges the rationale behind exclusionary approaches to nature conservation. Indicators are developed to facilitate a shift towards the widespread adoption of “human‐centered” conservation practices, in which nature conservation benefits from the inclusion and empowerment of human communities instead of their exclusion and marginalization.
