HMG appointed local consultants to undertake feasibility studies. However due to the insufficient working experience of the local consultants, the project feasibility studies need international supports to design the project with international best practice and innovation. 2. A project preparatory team (TRTA team) has been recruited by ADB for project preparation in December 2018, which has insufficient budget and expertise to undertake supplementary studies. The Concept Paper for the project was approved in Oct 2018 and is attached to this ToR. The composition of TRTA team is described in the concept paper for further reference. 3. The purpose of CDIA intervention is to provide additional project preparation resources and to support the innovative designs in the project, in the fields of watershed water quality modeling, storm water best management practice for urban first flush runoff management, information and communication technologies for urban environmental monitoring and big data analysis, climate change adaptation and mitigation in urban sewerage system upgrade and urban river flood control, and environmental monitoring and emergency response systems for industrial parks. 4. CDIA specialists are to introduce innovative technology and international best practice to support project design and feasibility studies. The final deliverables will be prepared in the form of knowledge products which will have both project specific recommendations and can be used as guidelines for further project design during implementation and for other projects in PRC as well. 5. A CDIA team project coordinator will be provided to offer logistics and coordination support to the CDIA individual specialists (including this position) and will also support liaison with the ADB team, PMO, FSR team, etc., to ensure smooth workflow. 1.2 OBJECTIVE AND PURPOSE OF THE ASSIGNMENT 6. A proposed loan of $100 million from the Asian Development Bank for Anhui Huangshan Xin'an River Ecological Protection and Green Development Project (HXEPGDP) has been included in the 2020 investment pipeline agreed upon between the Government of PRC and ADB. A project preparatory technical assistance (PPTA) for Preparing the HXEPGDP has been proposed to design the project and enhance project readiness. 7. The proposed project impact will sustain economic growth in the Yangtze River Economic Belt (YREB) as envisaged for the YREB Development Plan. The economic and environmental conditions in the upstream of Xin'an River will be improved consequently. The Project has four outputs: (i) Urban and rural point source pollution management will be installed; (ii) Non-point source pollution control will be enhanced; (iii) Green finance mechanism will be piloted; and (iv) Capacity for ecological system and project management will be strengthened. 1 8. Xin'an River is the main drinking water source for 10 million urban and rural residents in downstream areas in Zhejiang Province, and Huangshan city is situated in the upstream region of the Xin'an River Basin. Rapid economic development, urbanization, intensive agriculture production, and the growth of tourism in the area have increased both environmental and ecological pressures across the Xin'an River Basin. Both point sources (urban and rural sewage) and non-point sources (agriculture-based and run-off) have impaired the water safety in Xin'an River. To improve/maintain the level of water quality in the upstream reaches of Xin'an River, Huangshan city is in an urgent need of strengthened water management and sustainable green development. 9. The project area covers the overall Huangshan City including 3 districts (Huangshan District, Tunxi District and Huizhou District) and 4 counties (She County, Yi County, Qimen County and Xiuning County). The Project will upgrade and rehabilitate approximately 660 km of storm water sewers to serve over 400,000 urban population and significantly reducing storm water runoff directly discharged into Xin'an River with approximately 3,000 ton per year COD and 400 ton per year ammonia. The environmental monitoring systems will significantly improve the water and air quality controls, and industrial pollution over the whole urban areas of Huangshan City. The project will improve environmental and health conditions for urban residents, especially for poor households which are about 20% of the urban population. 10. Stormwater discharged from urban areas, especially the first flush from separate storm sewers and overflows from combined sewers, can contribute large pollution loadings to the upstream of Xin'an River. Urban sewerage modeling for planning and incorporating low impact development (LID) measures is essential for urban stormwater management to reduce

International Federation Appeal history: • Launched on 30 July 2007 for CHF 9,462,000 for 12 months to assist 400,000 beneficiaries. • Disaster Relief Emergency Funds (DREF): CHF 240,000 (USD 199,465 or EUR 146,468) was initially allocated from the Federation’s DREF to support the national society to respond. Summary: In late May, 2007, torrential rains and swelling rivers devastated more than 980 countries in 24 provinces, autonomous regions and municipalities of China, affecting an estimated 200 million people and resulting in more than 1,000 deaths. In the areas where the International Federation supported the flood operations, at least 243,000 houses were reported totally collapsed in five provinces: Henan, Hubei, Anhui, Sichuan and Chongqing municipality. It was reported to be the worst flooding seen in more than 50-80 years for some hard hit areas of the country. The Red Cross Society of China (RCSC) was able to respond rapidly and effectively to the needs of thousands of people affected by the floods.

In the current optimization of urban stock, it is faced with problems such as the decline of regional culture and the homogeneity of spatial form. By combing the historical evolution and value characteristics of Tunxi Old Street, introducing the concept of micro- regeneration, exploring the strategy of micro-regeneration of historical and cultural districts, this paper realizes the sustainable development of district from three dimensions of urban venation restoration, node space activation and building characteristics shaping, which can provide reference for the regeneration of other historical and cultural districts. 1 Introduction the district. This paper takes the micro-regeneration of Tunxi Old Street as an empirical study, exploring the As the key level of the protection system of famous development and advancement of the current historical cities in China, historical and cultural districts are a and cultural districts from the three dimensions of urban special type of heritage with dynamic characteristics, texture, node space, and architectural characteristics, which belong to the category of typical living heritage.
