Impacts Of Climate Change

High latitude agriculture is rainfed. Climate change could, however, increase water deficiency and initiate a call for development of irrigation systems as a part of field water management systems. This study aimed to develop a basic understanding about the current state of irrigation potential according to region by monitoring proximity of fields to waterways and characterizing their general conditions. One third of Finnish fields are in direct contact with a shoreline of an inland waterway. This coupled with Finland being water-rich country may improve adaptive capacity to cope with the potentially harmful impacts of climate change in the future. However, there are marked differences between regions in access to water resources. Findings of this survey will serve as background information needed to assess future needs for introduction of irrigation and to evaluate the opportunities to close yield gaps and improve yield stability through irrigation.

The scientific literature of the past decade contains a large number of reports detailing the development of downscaling methods and the use of hydrologic models to assess the potential effects of climate change on a variety of water resource issues. This article reviews the current state of methodologies for simulating hydrological responses to global climate change. Emphasis is given to recent advances in climatic downscaling and the problems related to the practical application of appropriate models in impact studies. Following a discussion of the advantages and deficiencies of the various approaches, challenges for the future study of the hydrological impacts of climate change are identified.

Abstract In the age of climate change, the efficient allocation, distribution and use of water raises complex issues for water management, with far-reaching and often contentious consequences. As water becomes scarcer, water-related tensions are imminent on different scales. It is the interplay of these tensions with a number of socioeconomic, political, environmental and cultural factors that determine the probability of conflict. Lamu found in the coastal part of Kenya, is a unique location in that access to water is already a major challenge. Combined with the negative impacts of climate change, and the on-going large infrastructural development in the region, Lamu is on the verge of a water crisis. As such, there is a need for research into the context specific factors that play a part in heightening the potential for water-related conflict amidst increasing water scarcity. The focus of this study was to identify and evaluate the context-specific factors that will amplify the potential for water-related conflict in Lamu. The findings suggest religion, migration, and poverty are factors that would heighten the potential for water-related conflict in the region amidst increasing water scarcity. The study recommends that these factors need to be addressed urgently and should be part of any water management mechanism in Lamu, in order to avoid water-related conflicts. Additionally, the findings imply that anticipating the stressors for water-related conflict in Lamu, will play a significant role in managing conflict and facilitating negotiations over the region's water resources.

Impacts Of Climate Change

The main goal of this research is to develop a 3D groundwater (GW) model using MODFLOW software to assess the potential effect of increasing pumping discharges on GW level in the Nile Delta Aquifer (NDA). In this study, the current state of the irrigation canals and GW recharge are considered in the GW model. The simulated GW level was compared with the observed GW level for model validation. Three vertical cross sections in western central and eastern areas of the ND are selected to check the impacts of GW pumping on variations of GW level. Ten scenarios of increasing the abstraction rates in all areas of the ND are tested. The results confirmed that increasing the pumping discharges has a substantial effect on decreasing the GW level in central and southern areas of the NDA. In addition, the tenth scenario is considered the last case where the drawdown of GW level reached 1.32, 1.59, and 2.41m in the southern boundaries. The findings of the study should be considered when studying the management of GW resources and the impacts of climate change on the ND.

Impacts Of Climate Change

Climate change is affecting every ecosystem on Earth. Though climate change is global in scope, literature reviews on the biotic impacts of climate change have focused on temperate and polar regions. Tropical species have distinct life histories and physiologies, and ecological communities are assembled differently across latitude. Thus, tropical species and communities may exhibit different responses to climate change compared with those in temperate and polar regions. What are the fingerprints of climate change in the tropics? This review summarizes the current state of knowledge on impacts of climate change in tropical regions and discusses research priorities to better understand the ways in which species and ecological communities are responding to climate change in the most biodiverse places on Earth.

Purpose This paper aims to describe how social capital is mobilized in the mediation of periurban water insecurity induced by urbanization and climate change. Investing in social capital through the process of creating mechanisms for civic engagement is an important means of building resilience of periurban communities. Design/methodology/approach This paper draws on ethnographic and action research. The main sources of data were direct observation of water appropriation and access and semi-structured interviews. Convenience, snowball and theoretical sampling were used. Findings The residents of periurban Gurgaon have lost access to water on account of urbanization and climate change. In this context, they mobilize social relationships to collectively improve their access to water. Norms of cooperation and kinship play an important role in the mediation of water insecurity. Creating social capital by building platforms for civic engagement helped to improve their water security. Originality/value While there has been much interest in issues of periurban water insecurity, the role of social capital in the mediation of water insecurity has received scant attention. At the same time, while scholars have been interested in the role of social capital in adapting to the impacts of climate change, it has scarcely been studied in a periurban context. This paper seeks to bridge this research gap.

Impacts Of Climate Change

Presently the world faces what most likely will be the greatest challenge humanity has ever faced. Climate change is a phenomenon, or rather a set of phenomena, that directly influences the daily lives of human populations all over the planet. However, this influence normally negative also affects ecosystems, with emphasis on agroforestry systems, of which human populations are directly dependent on food and in a large number of primary raw materials. It is with this premise as a starting point that this work makes an analysis on the current state of climate change in Portugal, since, being a country of Mediterranean climate influence, it should be one of the territories where changes will be felt with more intensity and severity. In this work, the current position on energy production in Portugal regarding Green House Gases (GHGs) emissions and the evolution prospects for the near future, namely in the perspective of the impacts caused on forest resources, are discussed.
