The urban metabolism model shows clearly that human settlements are the quality outputs of the transformation of inputs by an urban area through a metabolic process. This study seeks to bring to focus the drivers of human settlement dynamics in Bamenda 3, the manifestation of the dynamics and the functional evolution. The study made used of secondary data and information from published and unpublished sources. Landsat images of 1989, 1999 and 2015 were used to analyze dynamics in human settlement.

  • Developing Integrated and Sustainable Human Settlements
    developing integrated and sustainable human settlements 39 developing integrated and sustainable human settlements developing integrated and sustainable human settlements 1. Strategic objective The PGWC’s vision of an open opportunity society for all includes the development of integrated and sustainable human settlements with access to social and economic opportunities for all the province’s citizens. The PGWC aims to accelerate the provision of housing opportunities, including prioritising the on-site upgrading of informal settlements and the provision of serviced sites, in order to assist greater numbers of people and help more of those who are most in need – with limited or no access to basic services. Both government and citizens play a crucial role in an opportunity society. If the human settlements we build are to be sustainable, then housing benefi ciaries must take personal responsibility for their role. A key objective of the PGWC is to promote a sense of ownership among housing benefi ciaries and to increase awareness and acceptance of their rights and responsibilities. The PGWC faces a number of constraints in the provision of housing opportunities. These include limited fi nance and a shortage of well- located land. This means that the selection of housing benefi ciaries must not only be fair, but also seen to be fair, and, that we must make optimal use of the available resources to maximise the value we extract from every rand spent and every hectare developed. We also have a responsibility to use our natural resources as effi ciently as possible by building sustainably. This means mitigating both our impact on climate change and the effect of extreme weather conditions (e.g.

  • The Application of the Fuzzy Analytic Hierarchy Process in the Assessment and Improvement of the Human Settlement Environment
    sustainability Article The Application of the Fuzzy Analytic Hierarchy Process in the Assessment and Improvement of the Human Settlement Environment Yangli Zhang 1,* and Qiang Fan 2 1 College of Marxism, Sichuan University, Chengdu 610065, China 2 State Key Laboratory of Hydraulics and Mountain River Engineering, Sichuan University, Chengdu 610065, China; [email protected] * Correspondence: [email protected]; Tel.: +86-028-8599-6691 Received: 15 January 2020; Accepted: 19 February 2020; Published: 19 February 2020 Abstract: With the development of urbanization in developing countries, some large cities have experienced rapid population growth and industrial expansion in a short period of time. In order to reasonably expand the scale of the city and guide the orderly outward movement of population and industries, it is urgent to improve the human settlement environment (THSE) in the surrounding areas of large cities. In the case of limited financial funds, different areas around the city need to be improved one by one according to the order of improvement grades. Since THSE is a comprehensive system involving multiple levels and indexes, it is difficult to assess it in a simple way. The previous assessment of THSE mainly focused on qualitative and semi-quantitative aspects, with poor accuracy. In this paper, the author takes JianYang County under the jurisdiction of Chengdu City in Southwest China as an example and uses the Fuzzy Analytic Hierarchy Process (FAHP) to quantitatively calculate the improvement grade of THSE in 55 townships of JianYang County. The author carried out an investigation for more than one year. According to the actual situation of JianYang County, five primary indexes and 22 secondary indexes were selected to establish a comprehensive evaluation index system.

  • The Challenges of Implementing New Human Settlement in the 21 Century
    The challenges of implementing new human settlement in the 21st Century. Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Master in Philosophy by Moiad Almadani Date: February 2017 i Abstract There are many challenges for town and regional planning in the 21st century, due to the rise in the world’s population. It is forecast to be approximately two billion by 2050. In 2014, half of the world’s population lives in urban areas. (United Nations, 2014, p. 7). The big task for this century is to create new human settlements to meet the challenges of this population growth and increasing migration to towns and cities. Governments need to implement policies to improve the quality of life in both urban and rural areas. There are significant challenges, with an expected increase in demand for residential units, infrastructure and transport as well as the need to create more jobs (Hall, 2011; United Nations, 2014). The overall Aim of this thesis is to analyse the concept of the new human settlement and establish a framework that can be used for implementation of the new human settlement concept. The concept of new human settlements requires the integration of sustainability principles into the planning of new settlements. It seeks to further the wider agenda of sustainable development in urban and regional planning which aims at the management of urbanisation and urban growth to achieve a balance between economy, society and the environment in any development process, while ensuring the availability of resources and choices for future generations.

  • Evaluation of Heavy Metal Adsorption Onto Microplastics Abstract 1
    Evaluation of Heavy Metal Adsorption onto Microplastics Jasmine Anne Quiambao1, Jorge Gonzalez Estrella2, Kerry Howe3 [email protected] [email protected] Department of Civil Engineering University of New Mexico, Albuquerque, New Mexico [email protected] Civil & Environmental Engineering Oklahoma State University Abstract 1 This project evaluates the association of microplastics and heavy metals in freshwater systems. Microplastics are ubiquitous across aquatic environments. However, the studies on occurrences of microplastics in marine ecosystems are well-established compared to freshwater. Microplastics are defined as synthetic polymers with a diameter of <5mm. Microplastics with a diameter of <150 μm are of particular concern given their small size and their potential to be ingested. Microplastics could enter freshwater systems by recreational activities, solid waste dumping, wastewater treatment effluents, or other sources. The interaction of microplastics with other contaminants could enhance toxicity and threaten human health and the environment. Freshwater systems in New Mexico near abandoned mine sites have concentrations of heavy metals above the EPA maximum contaminant levels. This project aims to assess the adsorption of heavy metals onto microplastics in contaminated freshwater systems. This research is divided into two main tasks: (1) detection and characterization of microplastics in freshwater systems containing elevated concentrations of heavy metals; and (2) evaluation of heavy metal adsorption onto microplastics in laboratory experiments. Water samples from Tingley Beach, the Rio Grande, and Laguna Pueblo, NM were collected and analyzed for this research. This project provides information about the occurrence of microplastics in freshwater systems in New Mexico and the potential adsorption of heavy metals onto them. The accumulation of heavy metals and microplastics in aquatic ecosystems may increase the potential toxicity to various living organisms.
