Agriculture is likely to bear the brunt of the impacts of climate change. The extent to which these impacts are felt depends in large part on the extent of adaptation in response to climate change. The overall aim of this paper is to attempt to identify farmers’ knowledge, perceptions and risk responses towards climate change (or potential change). In order to achieve this goal, several specific objectives are pursued. First, the paper investigates whether or not farmers have perceived the long-term climate change and extreme weather events. Second, the paper describes how farmers respond to climate change and tries to assess the determinants of their adaptation. Based on data collected from a survey among farm households in three provinces in rural China, the findings demonstrate that farmers are aware of climate variability and identify the rising temperature, decreasing precipitation and the increasing frequency of drought. Only about 25% of farmers are willing to adjust their farming structures as a risk reaction. Household size, wealth, farm size, and the number of plots are found to be important factors that influence farmer adaptive capacity. Implications for policymaking on agriculture and adaptation to climate change will be to focus on providing farmers with information about the climate in time and facilitating enhancement of their adaptive capacity.

Extensive industrial development is a major challenge to ecological civilization construction. Industrial energy consumption and environmental pollution reduction are desperately needed. The Dongting Lake district, located in Wuhan and the Changsha-Zhuzhou-Xiangtan (CZT) pilot zone, bears the responsibility to ensure national food security and watershed ecological security, and it is an urgent need for the Dongting Lake district to accept the ecological transition of industries. On the analysis of the industrial development status and problems of the Dongting Lake district, some proposals based on the characteristics and reality of the district are pointed out, such as industrial cooperation, proper space layout, ecological innovation, industrial structure upgrading, building of ecological parks, clean production, elimination of backward production capacity, heavy metals governance and so on, as to develop the industrial ecology of the Dongting Lake district.

Engineering is a production activity aimed at increasing people’s utility; however, serious crises are frequently reported to be caused by engineering constructions, both for nature and human beings. Based on engineering theories of philosophy, systems and ecology, this paper analyzed the prevailing defects of traditional project management approaches, explored the importance of harmony in engineering and engineering management, and discussed the developmental inevitability, concept connotation and system structure of harmonious management for engineering.

The Mode of Urban Renewal Base on the Smart City Theory under the Background of New Urbanization
Yi-hua Mao,Hong-yu Li,Qin-rui Xu
Front. Eng. 2015, 2 (3): 261-265.

The Smart City, coordinated development of economy, ecology and society, is the future of cities. Urban renewal is an important way to build the Smart City. Based on the Smart City theory, the authors propose the “12345” model of urban renewal, which means developing a tailored proposal of the city and citizen, and building “one city management system, two supporting safeguard measures, three information infrastructure platforms, four urban management modes, and five application service systems.” The city will gain the ability of self-adjustment and self-improvement. Smart urban renewal model not only solves the problems of the city at this stage, but also promotes the all-round development of the city, and access to sustainable development.

The Supply Chain Contract Design under Cap-and-Trade Mechanism with Free Riding
Fu-qiang Wang,Jun Liu
Front. Eng. 2015, 2 (3): 277-286.
https://doi.org/10.15302/J-FEM-2015049
This paper studies the influence of free riding on enterprise product pricing and carbon emissions reduction investment, as well as the contract design to achieve supply chain coordination under the carbon trading mechanism. First, we discuss the situation where carbon emissions reduction investment affects the product price and income. It demonstrates that the optimal investment of the upstream manufacturer increases with the degree of the free riding of the downstream manufacturer. The upstream manufacturer can improve their carbon reduction investment and the whole supply chain achieves Pareto improvement when the investment cost sharing contract is introduced. Nevertheless, under the cost-sharing contract the optimal investment of the decentralized supply chain is still lower than that of the centralized supply chain, and only in some particular cases can the two types of supply chain achieve equal total profits. Then, we preliminarily explore the situation where the product price and income is influenced by carbon emissions reduction investment. The consequences indicate that the optimal investment of the upstream manufacturers in this situation is less than the former one’s, and the transfer payment mechanism is able to improve the level of the supply chain overall carbon emissions-reduction. Moreover, compared to the former situation, the effects of free riding of the downstream manufacturer are even more serious. The conclusions can provide some intellectual support for manufacturing enterprises to make reasonable emissions reduction strategies and coordinate the supply chain existing in free riding.

Dynamic Coordinated Management Model of Programme in Large-Scale Construction Company
Feng Guo,Yi-qi Chen,Yi-qing Cai
Front. Eng. 2015, 2 (3): 287-292.
https://doi.org/10.15302/J-FEM-2015041
Large-scale construction companies develop rapidly when facing more and more opportunities and challenges of programme contracting. However, project management technology, not meeting the requirements of firm growth, still stands proud, while relevant programme management methods have not been well studied. Therefore, this paper commences innovative application of coordinated management theory to programme management according to the need of changing the existing management mode in large-scale construction companies, then puts forward the dynamic coordinated management model composed of the dynamic coordination of function module, interface module, support module and evaluation module. Besides, coordination degree was introduced to make auxiliary analysis, so that companies can utilize internal and external resources more effectively to realize the goals of programme management as well as enterprise strategy.
