Impacts Of Climate Change

<p>Climate change represents a key challenge to the sustainability of global ecosystems and human prosperity in the twenty-first century. The impacts of climate change combined with natural climate variability are predominantly adverse, and often exacerbate other environmental challenges such as degradation of ecosystems, loss of biodiversity, and air, water and land pollution. Besides, rapid industrialization and increasing adaption of agrochemical based crop production practices since green revolution have considerably increased the heavy metal contaminations in the environment.</p><p>Assessing the impacts of climate change on our planet and addressing risks and opportunities is essential for taking decisions that will remain robust under future conditions, when many climate change impacts are expected to become more significant.</p><p>Here, we established a review survey to assess the impact of biochar amendment and agroforstry system on CO<sub>2</sub> sequestration and methaloid remediation.</p><p>Our data base showed that Agroforestry-based solutions for carbon dioxide capture and sequestration for climate change mitigation and adaptation in long-term is more practical and realistic options for a sustainable ecosystem and decreasing negative effect of climate change. This was more supported in arid and semi-arid regions as well as area with saline and alkaline soil (20%).</p><p>From a soil remediation standpoint, the general trend has been shifting from reduction of the total concentration to reduction of the physic-chemically and/or biologically available fractions of metals. This regulatory shift represents a tremendous saving in remediation cost. While metals are not degradable, their speciation and binding with soil through biochar amending reduced their solubility, mobility, and bioavailability. While agroforestry showed high efficiency in C sequestration (32%), biochar amendment raveled significant mitigation in heavymetals bioavailability (42%). However, studies which coupled both approaches are limited. Thus, we conclude that combined Agroforestry and biochar amendment regulates C sequestration and metalloids remediation more efficiently.</p>

Purpose – The purpose of this study is to put forward a methodological framework to provide a comparative assessment of available mitigation and adaptation strategies against climate change. Mitigation options aim at minimizing CO2 and other greenhouse gas emissions, in an effort to reduce the rate of increase in global temperature. On the other hand, adaptation options relate to the ability of the natural or human systems to handle the impact of the climate change and to adjust to its effects, seeking to eliminate the adverse consequences and take advantage of any beneficial outcomes. Design/methodology/approach – The methodology focuses on specific parameters, leading to the most efficient package of alternatives for the area of Greece. The selection of the “optimal” ranking of alternatives in a defined strategy is a sophisticated procedure, and a multi-criteria decision-making process was established. A questionnaire was designed and used as input to the overall framework, based on specific decision criteria. Climate change experts gave their feedback via a face-to-face interview. ELECTRE III multi-criteria decision analysis was adopted for the comparative evaluation, as it fits best to complex environmental problems. An “optimal” sequence of mitigation and adaptation strategies was provided for Greece. Findings – The use of renewable energy sources, increase of energy efficiency and improved forest management – tree planting and rational water management – are among the most promising options to strategically plan climate change mitigation and adaptation for Greece. Originality/value – The presented study provides an insight into alternative mitigation and adaptation strategies against climate change. The use of the multi-criteria analysis is an innovative approach to outline the optimal bundle of strategies. The methodology focuses on specific parameters, leading to the most efficient package of measures for the area of Greece. Such an approach is implemented for the first time in Greece, at least up to the authors’ knowledge, and provides a basis for strategic governance and policy modeling for the area under consideration.

Mountainous Country

Nepal is a mountainous country located in South Asia. Climate change is one of the challenging phenomena and various symptoms of climate change are already seen in Nepal. This paper is made by analyzing the impacts of climate change in different sectors of Nepal like on water, health, forestry, agriculture, biodiversity, temperature and so on. It has also highlighted the impacts from global to country level. This paper has discussed adaptation strategies applied in lee ward side that is Mustang district of Nepal. This study suggested that Nepal should promote eco-friendly as well as traditional practices in order to enhance climate change mitigation and adaptation strategies. The study further recommended to heighten developmental activities by considering sustainability of the availed resources and betterment of mountainous peoples’ lives in Nepal.

Change Mitigation

As users of forest products and guardians of traditional knowledge, women have always been involved in forestry. Nevertheless, their access to forest resources and benefits and participation in forest management is limited compared to mens despite the fact that trees are more important to women, who depend on them for their families food security, income generation and cooking fuel. This guide aims to facilitate the incorporation of a gender lens in climate change mitigation and adaptation operations in forests, with special attention to those framed in REDD. This guide addresses four themes value chains, environmental payment schemes, firewood and biodiversity that relate directly to 1) how climate change impacts affect women in the forest and 2) how mitigation and adaptation measures affect womens access to resources and benefits distribution.
