Land cover changes and carbon dynamics in Central India's dry tropical forests: A 25-year assessment and nature-based eco-restoration approaches.

Anthropogenic land use and land cover changes are major drivers of environmental degradation and declining soil health across heterogeneous landscapes in Central India. To examines the land cover changes and spatio-temporal variations in forest carbon stock and soil organic carbon (SOC) over the past 25 years in central India. Geospatial techniques, coupled with ground measurements were employed to detect changes in land cover, carbon stocks in vegetation, and soil carbon in various vegetation types. The results indicate that forested areas have decreased, while agriculture and habitation have expanded between 1997 and 2022. Vegetation C stocks varied significantly (P < 0.05) from 39.42 to 139.95 Mg ha-1 and the SOC varied from 7.02 to 17.98 Mg ha-1 under different soil profiles across vegetation types, which decreased with soil depth, while the pH and bulk density increased. The maximum bulk density in the soil was found at a depth of 40-60 cm (lower profile) in Bamboo Brake, while the minimum was observed under Dense Mixed Forest at a depth of 0-20 cm (top profile). The topsoil profile contributed 33.6%-39%, the middle profile (20-40 cm) was 33.6%-34.4%, and the lower profile was 26.5%-30.8% of soil organic carbon. The study site has experienced rapid carbon losses due to changes in land cover, such as illegal expansion of agriculture, encroachments into forest fringes, and activities like selective logging and overgrazing, which have degraded dense forests. The ecological engineering of degraded ecosystems poses a great challenge and application of complex biological, mechanical and engineering measures is highly cumbersome, expensive, uneconomical and practically not feasible for upscaling. Nevertheless, proposed nature-based solutions mimic natural reparation and processes provide sustainable interventions for the reclamation of ruined landscapes besides improving ecological integrity and rendering many co-benefits to ecosystems and human societies.

An assessment of compliance with the provisions of Cigarettes and Other Tobacco Products Act 2003: Is Shimla a smoke-free city?

Background: . Tobacco consumption in any form is a major contributor to non-communicable diseases, and it is the leading preventable cause of death worldwide. Secondhand smoke is also harmful. To halt the smoking epidemic and protect people from second-hand smoke, the Government of India enacted the Cigarettes and Other Tobacco Products Act (COTPA) in 2003. Methods: . We ascertained compliance with the provisions of COTPA 2003 at 183 public places and 41 transport facilities of Shimla city from August 2017 to July 2018. Results: . Only 48% of public places had good compliance with the provisions of COTPA 2003. On average, a public place was found to be compliant with 7 of 10 key indicators of Section 4. Educational institutes and government offices had a higher rate of compliance compared to other places. Active smoking and signages signalling ban on smoking were observed in 17% and 95.6% of public places, respectively. Smoking aids (e.g. ashtrays) were observed at <10% of places. A designated smoking area was not seen at any public place. Conclusion: . Overall compliance of the Act was low with less than half the places having satisfactory compliance with Section 4. There is a need to raise awareness about the negative effects of smoking on health and environment and ensure strict adherence to the provisions of COTPA 2003.

Creation of a Smoke-free Environment for Children: An Assessment of Compliance to COTPA 2003 Legislation in an Urban Area.

OBJECTIVE: To ascertain the compliance to Cigarette and Other Tobacco Products Act (COTPA) 2003 which ensures the protection of children from the adverse health effects of second hand smoke. METHODS: This cross-sectional study assessed the compliance of 32 educational institutions and 157 points of sale of Shimla city. RESULTS: About 88% of the educational institutions and mere 7.6% points of sale were found having good compliance to the key indicators. No point of sale was found within the premises of educational institutions; however, 26% were found selling tobacco products within 100 metres radius of an educational institution. 7.6% points of sale were found selling a tobacco product to children. CONCLUSIONS: Despite having the status of a smoke-free city, lapses were observed in compliance to the Act. Strict adherence to the provisions of the Act would ultimately lead to a smoke-free environment for our children.

Prevalence of cigarette smoking and its predictors among school going adolescents of North India.

BACKGROUND: Cigarettes smoking is a common mode of consuming tobacco in India. This habit usually starts in adolescence and tracks across the life course. Interventions like building decision making skills and resisting negative influences are effective in reducing the initiation and level of tobacco use. AIMS AND OBJECTIVES: The purpose of this study was to assess the prevalence of adolescent current cigarette smoking behavior and to investigate the individual and social factors, which influence them both to and not to smoke. METHODOLOGY: A cross-sectional study was carried out among school going adolescents in Shimla town of North India. After obtaining their written informed consent, a questionnaire was administered. RESULTS: The overall prevalence of current cigarette smoking was 11.8%. The binary logistic regression model revealed that parents' and peers' smoking behavior influence adolescent smoking behavior. Individual self-harm tendency also significantly predicted cigarette smoking behavior. Parental active participation in keeping a track of their children's free time activities predicted to protect adolescents from taking this habit. CONCLUSION: Our research lends support to the need for intervention on restricting adolescents from taking up this habit and becoming another tobacco industries' addicted customer. Parents who smoke should quit this habit, which will not only restore their own health, but also protect their children. All parents should be counseled to carefully observe their children's free time activities.

Economic impact of interventional study on rational use of antiseptics and disinfectants in Super Speciality Hospital of Nagpur.

OBJECTIVE: To measure the impact of interventions on rational use of antiseptics and disinfectants (A and D) for cost containment in Super Speciality Hospital (SSH) of Government Medical College, Nagpur (GMCN), India. MATERIALS AND METHODS: This study was conducted from October 2003 to March 2007 in SSH of GMCN. In the pre-interventional phase (Phase-I), purchase, stocking and distribution of A and D was studied to find problem areas. Based on this formative data an intervention was planned (Phase-II) during which rationing of the A and D was done. Rational quantities needed for different A and D procedures were calculated based on recommendations of National Aids Control Organization (NACO) with modifications to suit our hospital setup. Detailed information, education, communication and training about rational use of A and D were provided to the hospital staff. In the post-interventional phase (Phase-III), the use of A and D was rationalized at the distribution level and the efficacy of in-use A and D was tested at user sites. Data about medicine expenditure, patient record and A and D usage in various departments was obtained from hospital records. Savings on A and D as against total annual medicine expenditure was calculated taking the cost of A and D in the post-intervention period. RESULTS: The expenditure on A and D as a result of intervention decreased by 20.7%. Out of the total medicine expenditure, the expenditure on A and D which accounted for 6.2% before intervention, decreased to 1.95% after the intervention. CONCLUSION: The information, education and communication (IEC) interventions attempted by us resulted in significant decrease in the use and expenditure of A and D.
