In this research, the influence of community management of the rural Andean community of San Roque de Huarmitá on the condition of communal lands was analyzed: usufructuated lands (family management) and communal farm (collective management), through an evaluation of the institutional level (design principles) as an indicator of community self-management capacity and analysis of physical-chemical characteristics of soils. Research methods such as: ethnoknowledge and similarity analysis were also used. The results showed that the design principles were well implemented in relation to land use and that the physical-chemical properties differ significantly between the two types of communal lands, showing better fertility results in the usufruct lands. It was concluded that the Andean rural community has a robust level of self-management, that is, it has sustainable community management. Since the usufruct lands provide direct benefits to the families (good soil fertility and pasture production), while the communal farmlands, having extensive management, do not generate direct benefits. In other words, there is a prioritization for the care of the family resources before the community resources.

The rise in population has affected the environmental quality and liveability of urban areas. This brings in new challenges to address the resilience capacity of the cities. The multifunctionality of urban areas are considered to be one of the strategies to build urban resilience. The paper explores the development of multifunctional landscapes from a neighbourhood planning perspective. For this, it considers open spaces within a neighbourhood as an element which can be conserved and transformed to productive spaces where waste generated within a neighbourhood is treated and used for developing green spaces. Besides, the system provides an opportunity to transform such land parcels within the city into productive spaces thereby integrating solid waste management and landscape development sustainably. The proposed concept discusses the social, economic and environmental benefits of implementing such spaces which are inevitable in the pursuit of wellbeing and quality of life of the people in a resilient city. At a broader level, the system proposed contributes in making green spaces in any neighbourhood and in the long run, this concept should find its place in urban planning policies of similar city contexts to ensure that our cities, its system of waste management and their landscapes remain sustainable.

C-doped TiO2 (C-TiO2) was synthesised using a solvothermal method with ethanol/TBT/LDPE medium. Microstructure and elemental composition of C-TiO2 were analysed with TEM and XPS. An anti-bacterial device was utilized for photocatalytic inhibition of gram-positive and gram-negative bacteria. The device to measure bacteriostatic action was placed in a dark room, and the bacterial culture was placed in a holding cup which contained holding box and nanoparticulate C-TiO2. This approach was convenient for addition and removal of C-TiO2. Photocatalytic bacteriostasis by C-TiO2 under visible-light irradiation was quantitively assessed for bacteriostatic properties. Moreover, the qualitative assessment of anti-bacterial activity with C-TiO2 was less significant for gram-positive bacteria in comparison to gram-negative bacteria.

In this article we present the design of effective control strategies (IVE Model), to predict atmospheric pollutants, greenhouse gases and toxins, from mobile sources, made up of 800 motorized vehicles, obtained from the records of the transport office of the Provincial Municipality of Ica. through an inventory of emissions from mobile sources, emission factors, activity and distribution of the vehicle fleet. The results obtained are Carbon Monoxide (CO, 23235.23 t/year), Volatile Organic Compounds (VOC: 12123.55 t / year), Nitrogen Oxides (Nox: 361.76 t/year), Evaporative Volatile Organic Compounds (COVevap: 455.2 t / year), Particulate Material (PM: 361.76 t / year) and Sulfur Oxides (Sox: 50.75 t / year). Where the highest CO emissions are cars and motorcycles, representing 45.72% and 36% of the total CO emissions released in the study area. It is concluded that prevention measures and actions such as transport management, control of vehicular emissions, promotion of the use of clean fuels, as a way of mitigating the atmospheric pollutants that could be generated, be established.

A This study aims to determine the extent of waste management in Bantul Regency with the concept of policy implementation by Edward III, which consists of policy communication, policy coherence, and policy implementation consistency. The government and society are currently trying to manage 3R-based waste (Reduce, Reuse, and Recycle). Researchers used a qualitative descriptive method using secondary data consisting of literature, online media and the internet, and documents from the Bantul district government. The results of the study stated that: Bantul Regency Government is still not optimal in terms of waste management; this can be seen from the level of attention to waste management and management, which is still minimal, thus giving the result that the government has not succeeded in handling waste quickly, precisely and correctly. However, if seen from the amount of waste mass, there was a reduction from 202,910 tons (2019) to 192,021 tons (2020); this is because COVID-19 has stopped mobility and activities so that the amount of waste is not as much as in 2019. However, it should still be noted that waste management must be improved so that waste in the future does not become a new problem.
Experimental and Numerical Investigations into Temperature Distributions and VOC Conversion Rate of RTOLiu, Jingyin; Peng, Zhijun

As regulations for controlling VOCs (Volatile Organic Compounds) emissions have become more and more stringent, RTO (Regenerative Thermal Oxidizer) which involves heat exchange and storage, combustion and reaction processes has to be further optimised for enhancing the VOC treatment efficiency and reducing energy consumption. In this paper, influences of operating temperature distributions and internal flow fields on gas-out VOC concentration have been studied with experimental investigation and CFD numerical simulation. Experimental results shows that combustion temperature (around the combustor) plays more critical role than thermal storage bed temperature for affecting VOC flow-out concentration. By examining the internal flow and temperature distributions, modelling results demonstrate that fast heat transfer takes place in thermal ceramic beds and high temperature areas are formed around the combustor. At about 20 seconds after a bed working for gas-in flow, the heat transfer has demonstrated obvious attenuating. The research suggests that it is very challenging for simultaneously maintaining low gas-out VOC concentration and keeping low fuel consumption and low combustion temperature in RTOs.

Industrial heritage is unique in terms of its patterns, reuse characteristics, economic relevance and social operations. Under the government’s “Industrial Heritage Regeneration Project”, a menu of outcome/performance assessments have been in practice and have evolved. This paper combines expert methods, the Analytic Hierarchy Process, and the Multi-criteria Evaluation Method, along with qualitative and quantitative data, to clarify the hierarchical structure and weight of factors that influence outcome/performances. The research purpose is to establish an integrated multi-criteria performance evaluation model for the reuse of industrial heritage. The findings identify a long list of factors by crossing the four major factors concerning the reuse of industrial heritage, namely regeneration creativity, operational management, implementation effectiveness and sustainable developments. Regeneration creativity is considered as the most important element, and the presentation of thematic plans and characteristics is the most important influencing factor. It is suggested that clarifications should be made concerning the factors that affect different facets in the execution of reuse initiatives. The research findings can serve as a reference for decision-making in reuse and development by reflecting the culture and value for the reuse and implementations of industrial heritage.

Uncertainty is inherent to the decision-making process of flood risk management, and hence uncertainty management has been identified as crucial in the decision-making process. Flood management has been transformed towards flood risk management highlighting the stakeholder integration and adaptation to extreme flood events. Therefore, the development of multifunctional land uses over floodplains considering the multiple objectives of the stakeholders have become a key to manage uncertainty incorporated with flood risk management. Integration of multiple stakeholders in the decision-making process has been a challenging task. Therefore, spatial planning as a collaborative planning tool has become very important to manage flood risk. Operationalization of flood risk management is mainly governed by the characteristics of the planning processes and it is also coined with the governance context of each locality. However, the importance of the role of spatial planning in flood risk management is still hidden. Further, there is no common framework developed for structuring the complexity of the planning process. Therefore, this research attempts to develop a framework for the operationalization of flood risk management. The conceptual framework was developed based on a comprehensive literature review. Analytic Hierarchy Process (AHP) has been used and integrated with the Delphi technique to identify and calibrate the criteria and the sub-criteria of the framework. The developed framework has been validated with a case study. This research has been concluded that sixteen characteristics of the decision-making process contribute to the operationalization of flood risk management.
