The significance of biodiversity in the survival of human beings and enhancing the urban quality of life is evident from the empirical measurements and qualitative studies carried out across the globe. Despite its importance and value, burgeoning population and growing urbanization are posing a serious threat to biodiversity leading to biodiversity homogenization and ecosystem fragmentation. Moreover, studies reveal that management practices of biodiversity hardly take into account perception, needs, and knowledge of urban residents regarding biodiversity. Urban green spaces have a major role to play in the conservation of urban biodiversity. However, the triangular relationship between biodiversity, urban green spaces, and public perception is still unexplored. With this aim, the paper attempts to compile, analyze, and synthesize the empirical findings to understand the state-of-the-art knowledge regarding public perception of biodiversity in urban green spaces. The search strategy acquired for the selection of papers resulted in 43 papers from 22 different countries of the world. The paper focuses upon an inclusive definition of urban green spaces, thus encompasses a wide variety of urban and peri-urban green spaces, parks, gardens, and waterfront urban spaces. The analysis of literature pattern reveals a recent increase in studies related to biodiversity perception over the last 10 years. It indicates a strong geographic bias in publications as well. Studies of animals including birds, insects, and reptiles are found scarce compared to plant species. The study could identify potential variables affecting human biodiversity perception which include species literacy, visitation rate, preferences, recreational, health, and restorative benefits, vegetation characteristics, nature connectedness, and conservation support. The paper also proposes a framework for understanding biodiversity perception in urban green spaces that can assist in improving our understanding of the relationship between human interactions and natural environments and framing strategies for urban development, landscape planning, and community health promotions.

The wisdom of developmental activities that propose voluminous increase in the built infrastructure is questionable. These can seriously undermine the ability of quintessential small cities to retain the sociocultural and people centric character leading to a saner lifestyle in comparison to the burgeoning metros. This study is based in Nagpur, a Grade II city of central India. It presents a comparative analysis of three unique housing neighbourhoods developed in distinct temporal periods: historic, pre-globalisation, and post-globalisation. It focuses upon seminal parameters that are intrinsic to emotional well-being of residents and encourage positive behavioural responses. The methodology follows a qualitative approach through a study of morphological maps, non-participatory observation, and photo documentation. An argument is developed for a comprehensive urban development process, based upon respect for intrinsic socio-cultural values. It emphasises the need to celebrate and rejuvenate the thread of continuum for betterment of small cities. This enquiry resolves that to make a city smart and sustainable, efforts at people centricity are imperative along with ICT and other smart technologies of the future.

Aloe vera has been used for centuries and is presently widely exploited as a nutraceutical. It is available in the form of various health drinks and formulations such as capsules/ tablets or externally in the form of gels & creams. Being a potent immunomodulator, it can be used in various ailments as a single drug or in a combination therapy. The area of formulation research is lacking in understanding the correlation of unique active therapeutic agent acemannan - a glucomannan present in aloe vera and its dose, due to numerous physical, microbiological and biochemical factors interfering in the extraction/ processing of aloe vera juice. Studies are limited and generally becoming complicated because of not having ability to discriminate between different species, since a very few species have a therapeutic effectiveness amongst about 400 species of aloe vera found worldwide. Being sensitive to heat, enzymes and shock, it is a good subject for formulation researchers as there is a concern about aloe products having a little or no aloe in them. The current article is about chemistry of aloe vera in exploring its potential as a mainstay of chronic drug therapy.
