While the declining rate of urban security and its potential effects have been globally acknowledged, the ways urban neighborhood security shapes real estate markets in African cities remain largely unexplained. The purpose of this paper therefore is to present the findings from a study of the nexus between urban neighborhood security and home rental prices in Lagos, Nigeria.

This paper is based on the hedonic price theory, an objectively derived urban neighborhood security index (UNSI) and property rental price data in Ojo, Lagos, Nigeria. This is a quantitative cross-sectional study that employs multistage sampling survey procedure. Data are analyzed using descriptive statistics, nonparametric correlation and hedonic price function with ordinary least squares (OLS).

Results show that nearly 50% of the study area is prone to insecurity and average rental values in Ojo, Lagos range from N151329.41 ($302.66) to N167333.33 ($334.67) per annum. Correlation analysis shows that home rental prices have high, positive and significant correlations (rs = 0.725 and p < 0) with UNSI. After controlling for neighborhood and structural factors, it is found that urban neighborhood security positively influences home rental values as a unit improvement in security leads to N81000.00 ($162.00) increase in rental value per annum.

Urban neighborhood security risk threatens residential property values, creates unintended residential mobility and destabilizes families. Findings from this study point to the facts that security is a key component of urban housing values and developers, and real estate investors must ensure that this component is well factored into property design, construction and valuation.

This is perhaps the first study that uses an objectively derived UNSI to study home rental price dynamics in Nigeria. The study extends knowledge on urban housing price determinants and contributes to literature on the crucial place of security in property management.

The study attempted to assess the food security status of urban agriculture households in Ghana and India. Also, the extent of urban agriculture participation and its effect on food security in Ghana and India were examined.

A total of 650 urban agriculture farmers were interviewed for this study in Ghana and India. Food security status of urban households was assessed by the use of the Household Food Insecurity Access Scale, whereas the determinants of the extent of urban agriculture and its effect on food security were analysed by the use of the heteroskedastic linear regression and the Seemingly Unrelated Regression models, respectively.

From the study on average, households in Ghana were mildly food insecure, but that of India was moderately food insecure. The results further revealed that various demographic, economic, institutional and health and nutrition factors differently influenced urban food security and urban agriculture. Also, the extent of urban agriculture participation positively influenced food security.

Several studies in Asia (India) and Africa (Ghana) on urban food security have been geographically limited to New Delhi, Mumbai and Greater Accra, with few studies in the Middle Belt of Ghana, and Bihar in India. Besides, there is a limited, rigorous, empirical study on the effect of the extent of UA on food security in Asia (India) and Africa (Ghana) individually and together. Moreover, we extend the frontiers of the methodological approach by applying the Seemingly Unrelated Regression (SUR) model to understand if the factors that affect food-security accessibility based on two food security accessibility tools are correlated.

Access to food through retail supply chain distribution can vary significantly among the urban poor and leads to household food insecurity. The paper explores this sustainable supply chain phenomenon through a field study among South Africa's urban poor.

Urban metabolic flows is the theoretical basis in the context of supply chain management (SCM). The field study comprised 59 semi-structured interviews in one South African township. Data were recorded, transcribed and translated, and coded using NVivo 12 to provide an inventory of eight themes categorized and patterned from the analysis.

Findings indicate societal factors play a significant role affecting food distribution, access and security from a spatial perspective of retail outlet locations and a nutritional standpoint regarding quality and quantity of food.

The study is exploratory in one township, and while rigorously conducted, the generalizability of findings is limited to this context.

The study practically contributes by providing guidance for food retailers and policymakers to include nutritional guidelines in their distribution planning, as well as the dynamics of diverse neighbourhoods that exist in modern urban contexts.

New forms of retail food distribution can provide better security and access to food for the urban poor, contributing to Sustainable Development Goals (SDGs) 2 Zero Hunger and 11 Liveable Cities.

The study is interdisciplinary and contributes by linking UN SDGs and SCM through urban metabolic flows from development studies as an overarching framework to enable analysis of relationships between physical, social and economic factors in the urban environment.

The paper is a synthesis of the 2017 Global Food Policy Report, and the purpose of this paper is to put into perspective the major food policy issues, developments, and decisions of 2016 and highlights challenges and opportunities for 2017.

The paper presents an overview of recent changes in the global context for food security and nutrition, and synthesizes research findings on major issues that arise in an urbanizing world. Based on its findings, the authors present policy recommendations and areas for future research for food security and nutrition.

Urbanization is linked with dietary changes to more energy-dense diets, and, the triple burden of malnutrition is increasing, particularly in rapidly urbanizing developing countries. Rural-urban linkages are key to improving food security and nutrition in both rural and urban areas, and traditional agricultural value chains linking farms to cities are undergoing a “quiet revolution.” Governance to enhance food security in the context of rapid urbanization faces various challenges in the institutional, administrative, and political realms, especially for the informal economy in developing countries. To address the unique challenges of urbanization, policies will need to create enabling environments, promote efficient and inclusive value chains, improve governance, and promote tailored programs. Research gaps that need to be filled include better, updated, and disaggregated data on food security and nutrition, as well as an enhanced understanding of enabling environments.

The paper highlights the increasingly relevant issue of rapid urbanization, especially in developing countries, for food security and nutrition, and synthesizes recent research in this area.

This paper explores the challenges of food security from source to consumption of agri-food value chain by considering urban–rural linkages in city region food systems (CRFSs) and proposes a strategic framework for CRFS identifying strategies to promote urban–rural linkages among multiple stakeholders.

A qualitative case study approach to a fruit and vegetable value chain from rural source to consumption in the Colombo City region identifies the challenges of food security. A snowballing sampling method was used to gather information from retailers, wholesalers, commission agent, farmers and consumers. The data were collected through face-to-face interviews, observations and secondary data sources. The data were analysed using thematic analysis.

Challenges in food security in the value chain related to five areas: input and production, infrastructure, public institutional support and policy, finance, and food market. Colombo city is heavily dependent on food sourced from other cities due to limited land and lack of locally situated commercially oriented farmers.

This research is limited to a selected number of fruits and vegetables in the Colombo city region and leaves out other food items.

This study contributes to informing policy and decision-making processes to promote a more balanced rural to city food value chain in Colombo City that could benefit all stakeholders from rural small-scale producers to urban consumers.

Today, the presence of unwanted activities threatening the safety of the field, which has negative effects on daily life and social psychology, is increasing day by day. There is no doubt that it is inevitable to avoid these threats, but it is possible to take some measures to reduce the destructive power of these threats. Nowadays, increasing terrorist attacks increase the importance of field safety design in urban areas. There is a loss of life in attacks around the world. The subject of this study is to investigate the design criteria related to the built environment and the measures to be taken in the case of bomb attacks in the built environment. In this study, a checklist will designed to measure the security design process around the building. The checklist titles are taken mainly from the “Safety design and Landscape Architecture” series of the Landscape Architecture Technical Information Series/LATIS publications by the American Society of Landscape Architects (ASLA) and the Risk Management Series of the Federal Emergency Management Agency/FEMA (FEMA, 2003, 2007; LATIS, 2016) and others. The checklist created as a result of literature review will be tested in Istanbul Sultanahmet Square. As a result of the study, it was determined that improvements should be made in the areas of vehicular and pedestrian access, parking lots, lighting and trash receptacle designs around Sultanahmet Square.

This paper aims to understand the delivery of crime prevention through environmental design (CPTED) across Europe – from European-wide procedures through national schemes to effective local strategies.

The findings come from a review of published literature and reports, case studies and site visits conducted primarily during COST Action TU1203 (2013-2016).

Innovative approaches and methods to integrate crime prevention into urban design, planning and management have been generated by multi-agency partnerships and collaborations at European, national and city levels. Methods and procedures developed by the European Committee for Standardization (CEN) Working Group on “Crime Prevention through Urban Planning and Building Design” are pioneering. However, findings show that implementation is best achieved at a local level using methods and procedures tailored to the specific context.

In-depth research is required to appreciate subtle differences between local approaches and conceptual models developed to better understand approaches and methods.

Practitioners and academics working to prevent crime benefit from participation in focused, multi-agency collaborations that, importantly, facilitate visits to urban developments, discussions with local stakeholders responsible for delivery “on the ground” and structured and sustained exploration of innovations and challenges.

The authors hope that this paper will contribute to developing a new direction for CPTED practice and research that builds on significant progress in creating safer environments over previous decades.

The purpose of this study is to evaluate the efficiency of the relative performances of Mother’s canteen across the regions of Tamil Nadu and find out the determinants of inefficiencies in the scheme.

An untargeted food security scheme called Amma (Mother's) canteen was started in Tamil Nadu, India, with an aim to provide the urban poor with hygienic and healthy food at an affordable price. Along with secondary data, interviews were conducted to understand the operational details of Mother's canteen. Data envelopment analysis (DEA) was used to find the relative efficiency of the scheme operated by nine corporations.

Based on the daily expenditure, number of meals served and revenue, seven of nine corporations were found to be inefficient. Further, sensitivity analyses found that among six procurement variables, procurement (quantity and price) of black gram and cooking oil were determinants of inefficiency.

As an untargeted scheme, the cost of delivering service-based evaluation was used for performance evaluation. Policymakers could use centralized procurement instead of open market procurement at the corporation level and standardized ingredients' usage (quantity) to further reduce the cost of the food security scheme.

The proposed DEA model may be used by policymakers to empirically evaluate the food security scheme's delivery effectiveness across various corporations in a region. Inefficient branches are identified here with empirical support for further performance improvement changes.

There are limited number of studies evaluating untargeted schemes. This paper presents the challenges of evaluating an untargeted scheme which allows self-selection of beneficiaries. The outcome of this study will help in identifying inefficient corporations, and further, improve the performance and cost of delivering untargeted food security scheme.

To review the development of the security zone concept and introduce an approach for transforming these spaces into more effective public places.

The literature review was conducted by examining major books and journal articles in the urban planning, urban design, and landscape architecture literature (1970‐2004).

The review found that an effective response to security zones is to initiate a strategic planning process utilizing local knowledge and design expertise.

Security zones have numerous negative socio‐cultural and aesthetic impacts on their neighborhoods. The findings of the literature review and the new approach introduced can be a good way to strike a delicate balance between providing for necessary security and mitigating against those negative impacts.

This paper fulfills a need in the property management community to understand and manage the openness/security dilemma.

This paper aims to examine the effect of China’s unique household registration system (hukou) on stock market participation.

In an effort to estimate the effect of hukou on households' financial behavior, we draw on data from China Family Panel Studies (CFPS) and use probit model and tobit model to test the effect of hukou on households stock market participation.

The results are with strong interpretative power over the limited participation of stock market in China-investors living in urban areas with urban hukou are more likely to participate in stock markets and allocate a larger fraction of financial assets to stocks and remarkably robust to a battery of robustness checks. The dual structure of social security caused by the household registration system could explain this result. Furthermore, marriage plays such a role of integrating social resources attached to hukou that only the marriage of individuals with urban hukou could significantly promote households' participation in the stock market. For married families, a household in which both husband and wife have urban hukou has a greater possibility to invest in stocks relative to those with rural hukou.

This paper contributes to the literature in two ways. First, much literature focuses on the stock market limited participation puzzle and gives explanations from the perspectives of individual heterogeneity and financial markets. This paper examines the effect of hukou. Such an idea is instructive to some developing countries where residents are treated differently because of the institutional reason. Second, the effects we find are economically meaningful. Our estimates indicate that medical insurance attached to hukou can explain almost 58% of the impact of hukou, which suggests that the key to reforming China's current household registration system is to make welfare separate from hukou. Moreover, homogamy based on hukou widens the gap of households' risky assets, which provides a new view to understand the income gap in the cities of China and the heterogeneous effect of marriage on stock market participation.
