Anthropogenic effects

Ebook "SCIAMACHY - Exploring the changing Earth’s atmosphere" is a comprehensive summary describing the entire SCIAMACHY mission – from the very first ideas to the current results. It illustrates how the measurements are performed, how the trace gas concentrations are derived from the measured spectra and how the unique data sets are used to improve our understanding of the changing Earth’s atmosphere.

In ebook "Carbon sequestration in urban ecosystems" Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.

This thesis focuses on four constructs of perceived adverse impacts of climate change, perceived anthropogenic causes of climate change; perceived policy effectiveness, and feasibility to explain Australian public support for mitigation policies. The study draws from major theories in the field such as the Theory of Planned Behaviour, Risk Perception Theory, the Extended Parallel Process Model, and Social Dilemma literature.

Anthropogenic greenhouse gas emission poses as serious threat to our environment and it is therefore of utmost importance that efficient systems are developed to mitigate these issues. SF6, in particular, has attracted more attention in recent years due to its global warming potential which severely exceeds that of CO2.

This effect from climate makes it nearly impossible to segregate ignition points from locations, which were burnt several hours or even several days earlier. An increase in secondary burnt locations makes it difficult for machine learning algorithms to establish causality links with anthropogenic and other groups of variables.

Lagoons are valuable ecosystems providing various services, such as fishing, recreational activities, and land reclamation, as well as hosting high biodiversity. Although lagoons in Turkey cover a coastal area of more than 36,000 ha, few studies of them have been conducted. Therefore, two lagoons (Dalyan and Arapçiftliği) located on the coast of the Sea of Marmara in the Kocaçay Delta, which is under intense anthropogenic pressure, were investigated between November 2013 and March 2015 to examine the effects of environmental factors on taxonomic diversity.

In the era of conservation forestry, protection of floral and faunal diversity is important prerequisite. Due to the effective implementation of conservation strategies in the protected areas, growth of faunal population will be in increasing phase which leads to the expansion of home range and territory. The present investigation was conducted to assess the human influence on the corridor between Mudumalai Tiger Reserve and Mukurthi National Park in Tamil Nadu during the period from August 2014 to July 2015.T

Climate change is a natural and continuous process. But recent relatively rapid change in climate occurs due to anthropogenic activities which makes alarming attention because it contributes largely to global warming by affecting the greenhouse gases (GHGs) and aerosols. GHGs mainly CO2, methane, nitrous oxide CFC11, CFC12, HCFC22and HFC23 with different global warming potential accumulate in atmosphere and increase in concentration over time creating the so called “greenhouse effect”.

Soil represents one of the most diverse habitats for more than a thousand million bacterial species present on the earth. The maintenance of soil quality, fertility and structure is essential for the protection of the biodiversity and integrity of terrestrial ecosystems. Introduction of anthropogenic chemicals into soil may have lasting effects on soil microbial activities and thus soil health. Chlorpyrifos is a broad spectrum organo phosphorus insecticide, displaying insecticidal activity against a wide range of insects and other arthropod pests.

Nitrogen is the key nutrient factor that influences soil fertility and productivity. It is the mineral nutrient that exists in different forms, but nitrate form is the most preferred form by plants. Irrespective of the form in which N is applied to soil, it undergoes transformation viz. mineralization (ammonification, nitrification), denitrification etc. by enzymes produced by micro organisms.

Farmed ruminants form a very large portion of total anthropogenic methane emissions globally. Methanogens present in ruminal flora primarily uses Hydrogen [H] produced during anaerobic carbohydrate fermentation. Ruminal microflora can convert plant fiber unavailable for humans into microbial protein available for absorption for ruminants with biological value 70.

Heavy metals like cadmium, nickel, lead, chromium, mercury etc are important environmental pollutants in areas with anthropogenic pressure. Their presence in the atmosphere, soil and water, even in traces can cause serious problems to all organisms. Heavy metal accumulation in soils is of great concern in agricultural production due to the adverse effects on food quality, crop growth (Ma et al., 1994) and environmental health. Heavy metal bioaccumulation in the food chain can be especially highly dangerous to human health.

Forest ecosystems are among the most complex and heterogeneous terrestrial environments. Such heterogeneity is probably due to limited anthropogenic intervention and the perennial status of the primary producers especially forest trees. Soil microorganisms (e.g., bacteria, fungi and actinomycetes etc.) play a vital role in biogeochemical cycling in forest soils maintaining life on earth, fixing gases and breaking down of dead plant and animal matter into simpler substances that are used at the beginning of the food chain.

Ruminant livestock constitute worldwide the most important source of anthropogenic emissions of methane. There are two main factors influencing global warming change, an increase in greenhouse gas emissions and depletion of the ozone layer. Methane is associated with both factors. Ruminants (dairy, beef, goats, and sheep) are the main contributors to CH4 production. Their CH4 production is a natural and inevitable outcome of rumen fermentation.

Anthropogenic activities have been the main cause of perceived global warming later in the middle of 20th century. Tillage intensive and highly mechanized traditional agriculture production system has been identified responsible for soil erosion hazards, surface and groundwater pollution, and more water consumption. As a result, the agricultural production system is becoming unsustainable.

The study used a semi-structured interview method, the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) tool and general linear models to investigate the influence of natural and human-derived components on the rice provisioning service at six villages. The results showed that along with the importance of applying a fertilizer-based system in the terraced rice ecosystem, topology- and hydrology-based systems have been influencing significantly on water and nutrient supply for irrigation on terraced rice fields.
