Aims: Along with different initiatives in public and private sectors Chittagong city dwellers are also contributing to increasing urban greenery. This study was aimed to find their perception and contribution to urban greenery development. Place and Duration of Study: The study was carried out in the Chittagong city of Bangladesh in four different residential areas between May 2019 and June 2019. Methodology: We have surveyed 100 respondent families who were selected through purposive random sampling. After sorting we have used MS excel 2010 to analyze the data. Results: The study revealed that household people covered 13.04% of the total household area by greener infrastructure which is about 179.07sq.ft per household. In this study it is found that 49.99% of the respondents practice indoor plantation, 62.44% have roof-top gardening where only 17.61% have gardens in their premises. 128 species have been in their household area of which 36 flowerings, 33 fruits 36 vegetables, 12 medicinal additionally 11 are ornamental plant species. It has also revealed in the study that 14% house-hold directly uses the roof where 86% use containers for their rooftop garden. They use compost manure, inorganic fertilizer, and food waste as manure. Where 6% prefer composting, 73% is food waste and 21% use inorganic fertilizer. According to 27% of people, the environmental benefits derived from the household greenery are the main reason for developing their garden where 26% claimed it for recreation, 24% for aesthetic and 13% for the religious benefit and only 10% do it for monetary benefit. Conclusion: Household people can be an important catalyst for “Urban green infrastructure development.” Hope this study will be an expedient caseworker on the way of planning for sustainable Chittagong city development which will embed the Environment and Urbanism in a frame of ‘Sustainable Urban Development’.

Value Model

Urban green infrastructure has become an important concept for sustainable urban development. Regarding the joining up of green spaces into green networks, it can have major positive impacts on the environment, societies and economies, and ecology. This study proposes a value model for investing in urban green infrastructure, with impact factors including land use value, energy conservation value, carbon reduction, and disaster prevention value. It establishes that through the interaction between all four of these factors, urban green infrastructure investment increases net operating income. Additionally, as disaster prevention value increases, urban disaster risk declines, and this has an important positive effect on overall value. Our modeling also indicates that in the face of climatic extremes, the construction of urban green infrastructure is increasingly important, particularly in terms of energy value and disaster prevention value. Specific incentives and catalysts for promoting investment in urban green infrastructure are proposed.

Urban green infrastructure plays an increasingly significant role in sustainable urban development planning as it provides important regulating and cultural ecosystem services. Monitoring of such dynamic and complex systems requires technological solutions which provide easy data collection, processing, and utilization at affordable costs. To meet these challenges a pilot study was conducted using a network of wireless, low cost, and multiparameter monitoring devices, which operate using Internet of Things (IoT) technology, to provide real-time monitoring of regulatory ecosystem services in the form of meaningful indicators for both human health and environmental policies. The pilot study was set in a green area situated in the center of Moscow, which is exposed to the heat island effect as well as high levels of anthropogenic pressure. Sixteen IoT devices were installed on individual trees to monitor their ecophysiological parameters from 1 July to 31 November 2019 with a time resolution of 1.5 h. These parameters were used as input variables to quantify indicators of ecosystem services related to climate, air quality, and water regulation. Our results showed that the average tree in the study area during the investigated period reduced extreme heat by 2 °C via shading, cooled the surrounding area by transferring 2167 ± 181 KWh of incoming solar energy into latent heat, transpired 137 ± 49 mm of water, sequestered 8.61 ± 1.25 kg of atmospheric carbon, and removed 5.3 ± 0.8 kg of particulate matter (PM10). The values of the monitored processes varied spatially and temporally when considering different tree species (up to five to ten times), local environmental conditions, and seasonal weather. Thus, it is important to use real-time monitoring data to deepen understandings of the processes of urban forests. There is a new opportunity of applying IoT technology not only to measure trees functionality through fluxes of water and carbon, but also to establish a smart urban green infrastructure operational system for management.

Lack of sustainable strategic approaches has led to non-functional, unsafe, inaccessible, and fragmented urban green infrastructure within cities. In sub-Saharan African cities, the development and management of urban green infrastructure are not realized in many instances due to a lack of priorities and resources. The objective of the study is to develop strategic approaches that help to overcome the challenges of urban green infrastructure and promote a sustainable development and management system in Ethiopia with special references to the emerging towns of Oromia special zone that surrounds Finfinne. To design sustainable strategic approaches for an urban green infrastructure development and management system, the study collected data using key informant interviews, focus group discussion and document reviews. Findings identify seven potential strategic approaches that are needed to create a sustainable urban green infrastructure development and management system. Hence, improving the quantitative, qualitative, and accessibility standards on the provision of urban green infrastructure is needed for sustained development. Moreover, advanced development in budget allocation, capacity building, legal and institutional framework, awareness creation, and stakeholder’s involvement are also needed to promote a sustainable development and management system of urban green infrastructure in the urban centers of Ethiopia in general and emerging towns in particular.

Urban green infrastructure (UGI) provides multiple functions that combine ecological and social benefits. UGI is being increasingly promoted and implemented in the Global North. In other parts of the world, such as in the Global South, infrastructures for UGI implementation and promotion are sparse. The state of infrastructure development and informal settlements in the Global South present different constraints and demands that should be explicitly addressed. This study presents an approach to addressing the specific conditions and physical limitations of UGI development in urban areas of the Global South. A four-step methodology was developed to assess the implementation potential for retrofitted and multifunctional urban green infrastructure in public areas. This methodology consists of (1) an initial site analysis, (2) defining design criteria and general strategies, (3) exploring the different dimensions of multifunctionality as the basis for deriving spatial typologies, and (4) assessing spatial suitability for potential placements for UGI elements. The methodology was applied to a study area in the metropolitan region of San José, Costa Rica. The results indicate the potential to improve the hydrological (up to 34% of surface runoff reduction), ecological (an increase of green space by 2.2%, creation of 1500 m length of roadside greenery and two new habitat types), and social conditions (2200 m of road type upgrading) of the site through UGIs. This assessment of different multifunctionality dimensions can serve as a guide for future UGI promotion and implementation in urban areas of the Global South.

Though the development of green infrastructure in parks in Samut Sakhon province has been continuously implemented, there are still no research studies that have explicitly demonstrated the parks’ potential, nor any public opinions toward the development of urban green infrastructure in the parks that would be productive for the planning to efficiently improve and provide urban green infrastructure. As a result, this study had the following objectives: 1) To analyze the potential and networks of urban green infrastructure in parks in Samut Sakhon province, 2) To analyze the satisfaction of using the services and requirements of the urban green infrastructure development in the parks in Samut Sakhon province, and 3) To propose development guidelines in urban green infrastructure for the parks of Samut Sakhon province. The research instruments comprised a questionnaire, and the data were analyzed by using a scalogram. The results found that high-potential parks were not large in size, but they had all the complete components, as well as green infrastructure featured in the attributes of patch, matrix, and mosaic. Nevertheless, the green infrastructure development featured in the attribute of the corridor had disappeared in several sites of the green infrastructure in the parks. Likewise, the green networks of the parks, specifically those in the high-potential category, were not successive by walking. For this reason, the people were mostly satisfied with the convenient accessibility of the parks, but there were the requirements of paving the footpath, improving the landscape, and adding a variety of activities in the parks. Therefore, the development guidelines of urban green infrastructure in the parks should formulate more areas in the attribute of the corridor at the riverside and on the streets, conserve and increase the park areas by allowing public participation in the management, as well as apply urban planning measures to obtain the park area. In addition, a footpath and bike lane should be safely constructed in the high-potential parks. Simultaneously, the landscape should be adjusted in the low- and moderate-potential parks by launching pilot projects in the parks of the governmental agencies.

Policy monitoring and evaluation are important elements of the policy cycle, this help to initiate policy-makers to assess the proper implementation and adjust it as appropriate. This paper aims to evaluate the existing policy, strategies, and institutional arrangement on the development of urban green infrastructure in the three study areas; namely Hawassa, Wolayita Sodo, and Bodity town. Analyzing policy documents, key informant interview, and questionnaire survey were used to collect the required data. Descriptive statistics and policy analysis were also used to analyze the collected data from different sources. The study revealed that different strategies and standards were developed by the federal government, but it is not practically exercised at the regional and local level. The majority of government officials and experts agreed that existing policies and strategies related to UGI is not properly implemented. On the other hand, lack of policy and strategies are the major limitation in the development and management of UGI. Almost majority of the respondents confirmed that weak institutional arrangement has contributed to the poor implementation of UGI development. Lack of attention and awareness, the weak institutional arrangement is the main responsible factors for the absence of proper policy and poor implementation of strategies concerning UGI. Thus, actions needed for all the development of proper policies and strategies to improve UGI development.
