“…Point causes of pollution of water in urban areas include industrial and sewage discharges, which are very important and are often managed intensively. Based on this review of scientific literatures, it is stated clearly that eutrophication is a predominant problem in water sources brought about by over enrichment with phosphorus and nitrogen (Wu & Xie, 2011).…”

“…In areas with expanding population, agricultural production, construction and urbanization as well as human activities soil erosion is a major problem (Ding, Chen, Cheng, & Wang, 2015;Leh, Bajwa, & Chaubey, 2011;Wu & Xie, 2011). Among the factors that cause soil erosion is poor land management which causes damage to the soil and results in water runoff across landscape instead of adequate infiltration (Liu, 2016;Montgomery, Huang, & Huang, 2014;Nadeu, Berhe, de Vente, & Boix-Fayos, 2012;Niu et al, 2015).…”

Severe soil erosion challenges exist in China as a result of long-term human related activities and its erosion-prone land forms and climate. Anthropogenic forces that alter the physical landscape cause substantial soil erosion which have adverse impact on surface water bodies and therefore necessitating sediment control as important aspects of catchment management planning. In this review we focused principally on the erosion factors and how to prevent and/or mitigate them. The application of soil erosion models such as the universal soil loss equation, its modification and others were also studied. The results established by various researchers showed a relationship between impact of soil erosion and degradation on water quality indicating the source of pollutant as anthropogenic and industrial activities. These are the sources of particles and deleterious material that contribute to the surface water deterioration including the East Lake. The review revealed that erosion causes both on-site and off-site effects on land and also on water bodies thereby affecting its quality.

Drying Urban lakes: A consequence of climate change, urbanization or other anthropogenic causes? An insight from northern India

Urban lakes in many places around the world are rapidly becoming vulnerable because of such factors as urbanization, climate change, anthropogenic pollutant inputs, etc. The influence of such forcing factors on lakes hydrology must be correctly recognized and addressed in order to protect them over the long term. Facing similar challenges, Sukhna Lake, an urban lake in northern India, has apparently dried up frequently in the recent past. Numerous hypotheses were subsequently proposed to isolate the possible factors affecting the lake and its water budget, including the potential impacts of land use changes, climate change, anthropogenic activities and other natural processes. Using meteorological data, lake‐catchment information and a hydrologic model, these hypotheses were comprehensively analysed. Relevant data on rainfall, wind, temperature, lake inflows, groundwater, lake physical characteristics, catchment land uses, soil texture, etc., were gathered for the analysis. A temporal trend analysis of factors relevant to these hypotheses was undertaken to identify critical drivers of hydrological changes. A sensitivity analysis also was performed, using the lake water budget, to determine and prioritize the predominant factors affecting the lake, leading to the creation of an annual lake water budget for the period from 1971 to 2013, highlighting the lake inflows and outflows. The lake annual inflow (catchment run‐off) was computed by adopting a rainfall–run‐off model based on the SCS‐curve number. Lacking any anthropogenic water withdrawals, the outflow was quantified by estimating the evaporation loss (using the FAO‐based Penman–Monteith Equation). The results of the present study indicate that the process of siltation and the construction of check dams in the catchment, rather than urbanization and climate change, were the dominating reasons contributing to changes in the lake hydrology, and affecting the lake most in recent years.

“…Wuhan, as a city that has over 100 lakes, is rich in water resources (Figure 1). According to the Wuhan City Lake Protection Regulations issued by the Wuhan Water Administration, there are 166 lakes in the Wuhan Lake area [1], of which 40 are located in the central city of Wuhan. However, with the rapid development of industrialization, the water pollution in some lakes is serious due to such factors as reclamation of farmland, urban construction and the imperfect construction of the legal system of lakes and the inadequate implementation of the lake protection responsibility mechanism, the lake area is also shrinking [2], especially in Liangzi Lake, one of…”

The protection and management of lakes is closely related to people's quality of life and the rapid development of urban economy, and it is also an important aspect of realizing ecological sustainability. Hubei Province has over 1000 lakes, so the importance of the protection and governance of lakes is self-evident. Since the Lake Protection Regulations of Hubei Province came into being, Hubei Province has achieved the gradual extension and improvement of the system of responsibility for the protection of the lake. In order to understand the development of the system of responsibility for the protection of the lake and to explore the shortcomings in the implementation of the lake management system, this paper takes Wuhan city, capital of Hubei Province, as an example, as the object of research and evaluates the implementation effect of the lake protection mechanism and system after the promulgation of Hubei Province Lake Protection Regulations. According to the evaluation results, since the implementation of the regulations, the formal protection of lakes in Wuhan city has been promoted step by step, and the effect of lake management has also been remarkable. The government attaches great importance to lake protection, and the enthusiasm of government staff participating in this is increasing. However, the evaluation results also reveal some weaknesses of the current system of lake protection and governance, including the protection of lake quality, the perfection of the annual appraisal system and the administrative responsibility system, and the optimization of the lake garbage disposal system. On the basis of the results, this paper puts forward countermeasures and ideas to perfect the mechanism and system of lake protection and management in Wuhan city, in order to provide reference for the lake protection and management in other areas.
