The mortality of forest conservationists and soil conservationists in the United States Department of Agriculture (USDA) who died during January 1, 1970-December 31, 1979 (N = 1,411 white males) while actively employed or while receiving a pension was evaluated. The proportionate mortality analysis was used to identify cancers that might be elevated in this occupational group compared to the total U.S. white male population, whereas case-control analyses more rigorously evaluated the disease association with occupation. Controls were selected from employees at USDA who died of any cause of death other than that cause of death represented by the case. In case-control analyses, non-Hodgkin's lymphoma (NHL) and colon cancer demonstrated a statistically significant linear trend (p less than .05) with duration of employment as either a forest or soil conservationist, which suggests an occupational etiology for both diseases. Soil conservationists who were last employed after 1960 experienced significantly elevated risks for NHL (OR = 2.6) and colon cancer (OR = 1.8), whereas those last employed before 1960 were not at an increased risk. Among forest conservationists, the risk for both NHL and colon cancer appeared to be elevated before and after 1960.

Cryptogams as bio-indicators for ecosystem monitoring in Sri Lanka: a comprehensive review and recommendations.
Environ Monit Assess
November 2024
Department of Botany, Faculty of Science, University of Peradeniya, Peradeniya, Kandy, Sri Lanka.
Cryptogams, encompassing algae, fungi, lichens, bryophytes, and pteridophytes play essential roles in soil formation, nutrient cycling, and ecological stability. Sri Lanka faces numerous environmental challenges, including habitat loss, climate change, and pollution and there is an urgent need for effective monitoring programs to assess and mitigate these changes. This comprehensive review compiles existing literature on the importance of cryptogams and their responses to various environmental stressors and highlights the specific characteristics that make cryptogams valuable bio-indicators, such as their sensitivity to pollution, climate change, and land-use changes in habitats such as forests, agricultural lands, and urban areas, as well as their ability to accumulate and retain pollutants over time.

Forest soils serve as the greatest sink of terrestrial carbon (C) and have a significant impact on worldwide or regional C cycling. By reducing emissions and enhancing the C storage in forests, the environmental monitoring function of a forest ecosystem may be ensured. The study focused on measuring the densities of major nutrients in soil to gain insight into the C and nitrogen dynamics of the Himalayan sub-tropical forest ecosystem of India besides supplementing the information about the C storage potential of these forest soils.

Soil erosion is a problematic issue with detrimental effects on agriculture and water resources, particularly in countries like Pakistan that heavily rely on farming. The condition of major reservoirs, such as Tarbela, Mangla, and Warsak, is crucial for ensuring an adequate water supply for agriculture in Pakistan. The Kunhar and Siran rivers flow practically parallel, and the environment surrounding both rivers' basins is nearly identical.

Land desertification poses a significant challenge in the Brazilian semiarid region, encompassing a substantial portion of the country. Within this region, the detrimental effects of human activities, particularly unsuitable anthropic actions, have resulted in diminished vegetation cover and an accelerated rate of soil erosion. Notably, practices such as overgrazing and the conversion of native forests into pasturelands have played a pivotal role in exacerbating the process of land desertification.
