Abstract This article explores how researchers can apply social science methods and theoretical frames to capture how place-based communities are perceiving and responding to the immediate effects of global climate change. The study focuses on research with Viliui Sakha—native horse and cattle breeders of northeastern Siberia, Russia, who are increasingly challenged by one of global climate change’s most prevalent effects: altered water regimes. By applying the theoretical framework of political ecology, the article shows how researchers can better understand how affected peoples have, in this case, “water in mind” via their histories, cosmologies, and management practices of water. Such awareness can inform research activities and findings, facilitate effective adaptation, and, ultimately, affect policy. Given the widespread emphasis on adaptation, including the urgent need for, increasing interest in, and funding support for transdisciplinary research projects on adaptation, and the facilitative role researchers and policymakers can play in adaptation, this move to understanding and integrating a population’s shifting perceptions—in this case, of water in mind—into research is fundamental.

<p>Understanding the impacts of global climate change on the spatiotemporal pattern of hydrologic cycle and water resources is of major importance in highly developed watersheds all over the world. These impacts are strongly dependent on related changes in intensity and frequency of extreme climate events. Implementation of Best Management Practices (BMPs) and policy approaches at watershed and regional scales is essential for mitigating their negative impacts on soil and water conservation, and sustainable economic development. However, the uncertainty of BMP effectiveness including increasing variability of future water supply and changing magnitudes of nonpoint source pollution has to be accounted for in watershed planning and management. This paper provides a review and discussion on the impacts of global climate change on BMP’s hydrologic performance, the current progress on hydrologic assessment of BMPs, as well as the existing problems and countermeasures. Research challenges and opportunities in the field of hydrologic assessment of BMPs under global climate change are also discussed in this paper.</p>

Globalization notion is encountered not only economically, but also politically, culturally, technologically and ecologically. Environmental problems seen national at first glance can cause regional and subsequently global problems. Climate changes create regional, social and economic problems in terms of effects thereof. Many factors such as continuation of rapid population growth, proliferation of water problems, increase of global warming and irrevocable habits of countries can lead to world pollution and impairment of environment. Industrialization, population growth and excessive consumption tendency on the one hand and need for balanced use of natural sources such that energy can meet needs of future generations on the other hand has rendered “environment” and “development” subjects substitute for each other. While increase of welfare and happiness of people are aimed with economic development, socio-economical costs caused by global climate change threaten this welfare cycle. A variety of sources extinct due to global warming and some of them cannot be effectively used in a desirable level. This situation prevents economic productivity. Global climate change problem should be reevaluated with not only conventional sustainable development approach but also in a global plane containing new political ecology notions such as “environmental justice” and “climate justice”. For this purpose, each of us has a role to play and also, novel law and policies are required that will lead global-scale solutions. In this study, relationship between global climate change and sustainable development approach will be handled within the scope of a new tendency.

Characterizing the response of ecosystems to global climate change requires that multiple aspects of environmental change be considered simultaneously, however, it can be difficult to describe the relative importance of environmental metrics given their collinearity. Here, we present a novel framework for disentangling the complex ecological effects of environmental variability by documenting the emergent properties of eelgrass (Zostera marina) ecosystems across ∼225 km of the Atlantic Coast of Nova Scotia, Canada, representing gradients in temperature, light, sediment properties, and water motion, and evaluate the relative importance of different metrics characterizing these environmental conditions (e.g., means, extremes, variability on different time scales) for eelgrass bioindicators using lasso regression and commonality analysis. We found that eelgrass beds in areas that were warmer, shallower, and had low water motion had lower productivity and resilience relative to beds in deeper, cooler areas that were well flushed, and that higher temperatures lowered eelgrass tolerance to low-light conditions. There was significant variation in the importance of various metrics of temperature, light, and water motion across biological responses, demonstrating that different aspects of environmental change uniquely impact the cellular, physiological, and ecological processes underlying eelgrass productivity and resilience, and contribute synergistically to the observed ecosystem response. In particular, we identified the magnitude of temperature variability over daily and tidal cycles as an important determinant of eelgrass productivity. These results indicate that ecosystem responses are not fully resolved by analyses that only consider changes in mean conditions, and that the removal of collinear variables prior to analyses relating environmental metrics to biological change reduces the potential to detect important environmental effects. The framework we present can help to identify the conditions that promote high ecosystem function and resilience, which is necessary to inform nearshore conservation and management practices under global climate change.
