Forests play a critical role in combating climate change and promoting sustainable development. They are often referred to as the "lungs of the Earth" because they absorb carbon dioxide and release oxygen, making them vital for regulating the planet's climate and supporting life. Forests act as carbon sinks, absorbing and storing significant amounts of carbon dioxide from the atmosphere. Trees, through the process of photosynthesis, convert carbon dioxide into organic matter, which is stored in their biomass and in the soil. This process helps reduce the concentration of greenhouse gases, mitigating climate change. Forests are home to a vast array of plant and animal species. Biodiversity is essential for the stability and resilience of ecosystems. Maintaining healthy and diverse forests helps ensure that ecosystems can adapt to changing environmental conditions and continue to provide ecosystem services that support sustainable development. Forests contribute to climate regulation by influencing temperature, precipitation, and weather patterns. They release water vapor into the atmosphere through a process known as transpiration, which can lead to increased cloud cover and precipitation, thus affecting local and regional climates. Forests play a crucial role in protecting watersheds and maintaining the quality and availability of freshwater resources. Tree roots stabilize soil, reducing erosion and maintaining water quality. Forested areas often act as natural filters, removing pollutants and sediments from runoff. Forests provide livelihoods for millions of people worldwide, especially in rural areas. Sustainable forest management practices can ensure a steady supply of timber, non-timber forest products, and ecosystem services, contributing to the economic well-being of local communities. Forests offer various ecosystem services, including regulating services (climate regulation, water purification, erosion control), provisioning services (timber, fuelwood, non-timber forest products), cultural services (recreation, spiritual value), and supporting services (nutrient cycling, pollination). Adopting sustainable forest management practices is crucial to maintaining the benefits provided by forests. Sustainable logging, afforestation, and reforestation efforts can help maintain and even enhance the carbon sequestration capacity of forests. Recognizing and respecting the rights of indigenous peoples in forest management is essential. Indigenous communities often have valuable traditional knowledge of sustainable forest practices and can play a key role in conservation and sustainable development efforts. Efforts to restore degraded forests and establish new forested areas (reforestation and afforestation) can contribute to climate change mitigation and the protection of biodiversity. Global agreements such as the Paris Agreement and the United Nations Sustainable Development Goals (SDGs) acknowledge the importance of forests in climate action and sustainable development, providing a framework for global cooperation. In conclusion, forests are integral to addressing climate change and promoting sustainable development. Efforts to conserve and sustainably manage forests are essential to achieving environmental, social, and economic goals at both local and global levels. Recognizing the multifaceted benefits of forests and integrating them into climate and development strategies is crucial for a more sustainable and resilient future.

The perishable nature of flowers urge for their appropriate post harvest management especially storage and packaging that keep the quality and potential vase life for better value. Gladiolus, commonly called as Sword lily, is a commercially important cut flower crop with elegant spikes, bright florets and good keeping quality. In the present study, we investigated the physiological and biochemical attributes affecting post harvest life of gladiolus spikes after packaging and storage. The spikes of four gladiolus cvs. Punjab Glance, Punjab Glad-1, Punjab Glad-2 and Punjab Pink Elegance were harvested at tight bud stage and packed in PP sleeves (25 ?m) and stored vertically at 4-5°C for 6, 9 and 12 days. After storage, the post harvest quality of both packed and unpacked spikes declined with more adverse effect on unpacked spikes. Among different storage durations, the spikes stored for 9 days showed good keeping quality parameters viz., vase life, per cent flower opened, floret size, days to opening of basal floret, maximum number of florets open at one time and water absorbed per spike which were at par with spikes stored for 6 days. The spikes stored for 12 days were found to be unacceptable in comparison to freshly harvested spikes and spikes stored for 6 and 9 days. The improved quality of spikes stored in sleeves could be accounted due to higher membrane stability index, relative water content, catalase and peroxidase activity as compared to unpacked spikes. Thus, loss in quality of spikes as compared to fresh during storage up to 9 days in PP sleeves is better than the complete loss of produce during transportation and gluts. Hence, the spikes of gladiolus could be stored dry at 4±0.5°C in PP sleeves for 9 days without much influence on its post harvest quality.

Abstract The effect of different modified atmosphere packaging regimes on the behavior of Salmonella spp. on minced meat was studied. Minced meat was experimentally contaminated with a Salmonella spp. cocktail (S. Enteritidis, S. Typhimurium, S. Infantis and S. Arizonae), packaged under vacuum or modified atmosphere with initial headspaces containing 20%O2/50%CO2/30%N2 and 20%O2/30%CO2/50%N2) and stored at 3 ± 1 °C for 12 days. Samples were analyzed for Salmonella spp., viable and lactic acid bacteria count every third day. Salmonella spp. counts decreased during storage in all packaging types, with reductions of about 1.5 log CFU/g. A significant difference (p < 0.01) was noted between Salmonella spp. counts in meat packaged in vacuum and modified atmospheres, although there was no significant difference in Salmonella spp. count between meat packaged in 50%CO2, and meat packaged in 30%CO2. At the end of the study, there were significant differences (p < 0.01; p < 0.05) in total viable and lactic acid bacterial counts between meat packaged in vacuum and modified atmosphere, and the lowest counts were noted in meat packaged in modified atmosphere with 50%CO2.

Many studies have shown that climatic and pollutant variables are directly related to the increase of hospitalizations due to respiratory diseases, mainly asthma. The aim of this study was to estimate the association between exposure to climate variables, pollutants, aerosols and hospitalizations due to asthma. This ecological study used time series with daily asthma hospitalization indicators, and concentrations of pollutants, climate data and aerosols, between January 2013 and December 2013. A generalized additive model using Poisson regression was used to estimate the relative risk with a two-day lag after exposure; the unipollutant model was adjusted by the apparent temperature, a measure defined from the temperature and relative humidity of the air, and a variable was added to control the seasonality and the day of the week. As a result, the values of relative risks (RR) for hospitalizations due to asthma were: for minimum temperature RR= 0.8985; maximum humidity RR= 0.9819; wind speed RR= 0.9419; rain RR= 0.9834; ozone RR= 0.9735; aerosols (AOT) RR= 1.0078; clearness index (Kt) RR= 0.0492 and carbon monoxide RR= 1.0865 for a two-day lag. After considering the aforementioned factors, we found the values of B coefficients. Exposure to climatic variables, pollutants, aerosols and clearness index was associated with hospitalizations due to asthma, and provided subsidies for the implementation of preventive measures to decrease these outcomes

Objective To analyze the onset time rule of spontaneous pneumothorax ,and investigate the influence of climatic factors such as atmo-spheric pressure,wind speed,etc. on the onset of spontaneous pneumothorax. Methods Five hundred and ninety-three patients of spontaneous pneumothorax in Cenral Hospital Affiliated to Shenyang Medical College were enrolled for this study between January 1,2011 and December 31, 2015. The data of the average daily atmosphere pressure and wind speed in five years were recorded. The relationship between the onset of sponta-neous pneumothorax and the change of the atmosphere pressure and wind speed was analyzed. Results The incidence of spontaneous pneumotho-rax in Shenyang area was obvious seasonal. Primary spontaneous pneumothorax episodes were observed mostly in spring and in March and April;Second spontaneous pneumothorax episodes were observed mostly in winter and in November and December. The difference in mean atmospheric pressure was 0.6 hPa lower than on days in which no spontaneous pneumothorax occurred. This difference was statistically significant(P=0.015). We observed significantly higher average wind speed on days with SP versus days without(9.46±6.33 m/s vs 7.11±5.47 m/s,P<0.001). Conclu-sion Spontaneous pneumothorax has obvious aggregation of onset time. A sharp drop in atmospheric pressure and increases in wind speed has im-portant influence on the incidence of spontaneous pneumothorax.
