Water level dynamics of Wetlands are influenced by both climate change and human activities. Understanding the influence characteristics is important for the management of wetland water resources and ecology. Based on the water level dynamic and precipitation of the Baiyangdian Wetland, and the NPI index, the paper analyzes the response characteristics of the water level dynamic to the precipitation, and the teleconnections between the water level dynamic and the NPI by adopting method of wavelet analysis. Results show that climate change plays an important role on the response of the water level dynamic to the precipitation and also to the NPI, and human activities can significantly change the response characteristics. The response time lags of the water level dynamics to the NPI is longer than that of the water level dynamics to the precipitations, which indicates that the wetland precipitation might be partially influenced by the NPI. The knowledge of the response characteristics obtained in the paper is beneficial for water conservancy and control of the wetland, and is favorable for the sustainable development of its eco-environment.

AbstractThis research quantitatively and qualitatively analyzes the factors responsible for the water level variations in Lake Toba, North Sumatra Province, Indonesia. According to several studies carried out from 1993 to 2020, changes in the water level were associated with climate variability, climate change, and human activities. Furthermore, these studies stated that reduced rainfall during the rainy season due to the El Niño Southern Oscillation (ENSO) and the continuous increase in the maximum and average temperatures were some of the effects of climate change in the Lake Toba catchment area. Additionally, human interventions such as industrial activities, population growth, and damage to the surrounding environment of the Lake Toba watershed had significant impacts in terms of decreasing the water level. However, these studies were unable to determine the factor that had the most significant effect, although studies on other lakes worldwide have shown these factors are the main causes of fluctuations or decreases in water levels. A simulation study of Lake Toba's water balance showed the possibility of having a water surplus until the mid-twenty-first century. The input discharge was predicted to be greater than the output; therefore, Lake Toba could be optimized without affecting the future water level. However, the climate projections depicted a different situation, with scenarios predicting the possibility of extreme climate anomalies, demonstrating drier climatic conditions in the future. This review concludes that it is necessary to conduct an in-depth, comprehensive, and systematic study to identify the most dominant factor among the three that is causing the decrease in the Lake Toba water level and to describe the future projected water level.

In recent years, the influence of climate change and human activity on the global environment have become a concern. It is essential to better understand the hydrologic environment to evaluate water availability and related issues. In this study, we perform a trend and breakpoint analysis on streamflow time series in the Lanyang, Keelung, Dahan, Fengshan, Youluo and Shangping River Basins in northern Taiwan. Furthermore, we apply the Budyko–Fu equation and the Budyko–Mezentsev–Choudhury–Yang equation to evaluate the elasticity of streamflow with respect to climate factors and the catchment characteristics parameter. We discuss the sensitivity of streamflow to climate factors (precipitation and potential evapotranspiration), as well as sensitivity to human activities such as land use changes. We detected breakpoints in the streamflow time series for the Lanyang and Keelung rivers in in 1993 and 1990, respectively. The streamflow of Lanyang River increased by 32.50% during the variation period (1993–2017), with 109.00% of the variation caused by non-climate factors. The Keelung River’s streamflow was reduced by 18.11% during the variation period (1990–2017), and the dominant factor was climate change, accounting for 71.53% of the reduction. Sensitivity analysis showed that precipitation changes were the most sensitive factor of streamflow variation. For every 1% increase in precipitation, the streamflow would increase by 1.05% to 1.37%. These results could serve as a reference for the sustainable development of water resources and territorial policies in northern Taiwan.

The Impact

Climate change and human activities cause lake water level (WL) fluctuations to exceed natural thresholds, with implications for the available water resources. Studies that explore WL change trends and the main driving forces that affect water level changes are essential for future lake water resource planning. This study uses the Mann–Kendall trend test method to explore the WL fluctuations trend and WL mutation in Erhai Lake (EL) during 1990–2019 and explore the main driving factors affecting water level changes, such as characteristic WL adjustments. We also use the principal component analysis to quantify the contribution of compound influencing factors to the water level change in different periods. The results showed that the WL rose at a rate of 47 mm/a during 1990–2019 but was influenced by the characteristic WL adjustment of EL in 2004 and the WL mutation in 2005. In 1990–2004, the WL showed a downtrend caused by the increase in water resource development and utilization intensity, and in 2005–2019, the WL showed an uptrend caused by the combined decrease in evaporation, outflow, and the increase in water supply for water conservancy projects. Additionally, the largest contributions of outflow to WL change were 19.34% and 21.61% in 1990–2019 and 1990–2004, respectively, while the largest contribution of cultivated area to WL change was 20.48% in 2005–2019, and it is worth noting that the largest contribution of climate change to WL change was 40.35% in 2013–2019. In the future, under the increase in outflow and evaporation and the interception of inflow, the WL will decline (Hurst exponent = 0.048). Therefore, planning for the protection and management of lakes should consider the impact of human activities, while also paying attention to the influence of climate change.

For this reasons, a robust controller that allows dealing with large variation in operating conditions is proposed to control the water level of a multi-pool open irrigation canal prototype. The main objective of this study is to regulate the downstream level of each canal's pool at a constant value even with inflow disturbances.  The robust controller is designed and tested in simulation for different operating conditions.

“We regard the recent science –based consensual reports that climate change is, to a large extend, caused by human activities that emit green houses as tenable, Such activities range from air traffic, with a global reach over industrial belts and urban conglomerations to local small, scale energy use for heating homes and mowing lawns. This means that effective climate strategies inevitably also require action all the way from global to local levels. Since the majority of those activities originate at the local level and involve individual action, however, climate strategies must literally begin at home to hit home.”

This chapter explores the relationship between international development and global health. Contrary to the view that development implies ‘good change’, this chapter argues that the discourse of development masks the destructive and exploitative practices of wealthy countries at the expense of poorer ones. These practices, and the unregulated capitalist economic system that they are part of, have created massive inequalities between and within countries, and potentially catastrophic climate change. Both of these outcomes are detrimental to global health and the millennium development goals and sustainable development goals do not challenge these dynamics. While the Sustainable Development Goals acknowledge that inequality and climate change are serious threats to the future of humanity, they fail to address the economic system that created them. Notwithstanding, it is possible that the enormity and proximity of the threat posed by inequality and global warming will energise a counter movement to create what Kate Raworth terms ‘an ecologically safe and socially just space’ for the global population while there is still time.

The Impact

Abstract This workshop is dedicated on SDGs in the focus of environmental and health issues, as very important and actual topic. One of the characteristics of today's societies is the significant availability of modern technologies. Over 5 billion (about 67%) people have a cellphone today. More than 4.5 billion people worldwide use the Internet, close to 60% of the total population. At the same time, one third of the people in the world does not have access to safe drinking water and half of the population does not have access to safe sanitation. The WHO at UN warns of severe inequalities in access to water and hygiene. Air, essential to life, is a leading risk due to ubiquitous pollution and contributes to the global disease burden (7 million deaths per year). Air pollution is a consequence of traffic and industry, but also of demographic trends and other human activities. Food availability reflects global inequality, famine eradication being one of the SDGs. The WHO warns of the urgency. As technology progresses, social inequality grows, the gap widens, and the environment continues to suffer. Furthermore, the social environment in societies is “ruffled” and does not appear to be beneficial toward well-being. New inequalities are emerging in the availability of technology, climate change, education. The achievement reports on the Sustainable Development Goals (SDGs), also point out to the need of reviewing individual indicators. According to the Sustainable Development Agenda, one of the goals is to reduce inequalities, and environmental health is faced by several specific goals. The Global Burden of Disease is the most comprehensive effort to date to measure epidemiological levels and trends worldwide. It is the product of a global research collaborative and quantifies the impact of hundreds of diseases, injuries, and risk factors in countries around the world. This workshop will also discuss Urban Health as a Complex System in the light of SDGs. Climate Change, Public Health impacts and the role of the new digital technologies is also important topic which is contributing to SDG3, improving health, to SDG4, allowing to provide distance health education at relatively low cost and to SDG 13, by reducing the CO2 footprint. Community Engagement can both empower vulnerable populations (so reducing inequalities) and identify the prior environmental issues to be addressed. The aim was to search for public health programs using Community Engagement tools in healthy environment building towards achievement of SDGs. Key messages Health professionals are involved in the overall process of transformation necessary to achieve the SDGs. Health professionals should be proactive and contribute to the transformation leading to better health for the environment, and thus for the human population.
