Abstract:The Ili River is a transboundary river shared by China, upstream, and Kazakhstan, downstream. The Ili is the main water supplier to Lake Balkhash, the largest lake in Central Asia after desiccation of the Aral Sea. Agreements over water allocation have not been concluded between China and Kazakhstan. This paper investigated water consumption of agriculture and riparian ecosystems in the Ili river basin, to provide information for further debate on water allocation, through the Simplified Surface Energy Balance Index (S-SEBI) approach using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images. The overall water consumption in the Ili river basin was 14.3 km 3 /a in 2000, 17.2 km 3 /a in 2005, and 15 km 3 /a in 2014. In 2000, China and Kazakhstan consumed 38% and 62% of the water, respectively. By 2014, the relative share of China's water consumption increased to 43%. In China, 80% of the water consumption is due to agriculture. High runoff during the past 10 years enabled increasing water consumption in China and sufficient water supply to agriculture and riparian ecosystems in Kazakhstan. When runoff of the Ili River decreases, as expected for most rivers in Central Asia, then irrigation efficiency has to be further increased in China, and irrigation systems in Kazakhstan have to be restored and modernized in order to reduce water consumption and protect Lake Balkhash and the riparian ecosystems.

Since 1992 the provision of agri-environmental schemes (AESs) has been obligatory for member states of the European Union. However, decisions concerning the actual design of schemes and measures are left to member states who have to integrate this policy within their administrative structures and to comply with the general rules laid down in the EU rural development regulations. Over time, the respective council regulations have increasingly encouraged member states to design agri-environmental policy in a sub-national, decentralised and participatory way. However, the response to these opportunities has been quite diverse amongst the member states. This paper presents the results of a unique expert survey in nine different member states, focusing on decentralisation and participation. The results show that the way in which decisions are made affects the environmental effectiveness of AES. In particular, the involvement of actors at a local level and the participation of environmental NGOs have a positive effect on the environmental effectiveness of AES. Therefore, it is not surprising that most actors involved in decision making surrounding AESs are in favour of further decentralisation and participation in order to tackle agri-environmental problems. However, actors from the agricultural administration and agricultural associations, which are the most influential groups in terms of the design of AESs, oppose extending participation to the local level and to environmental associations.agri-environmental policy, decentralisation, participation, levels of decision, interest groups, European Union, EU member states, political economy, public transaction costs,

Assessing an adaptive cycle in a social system under external pressure to change: the importance of intergroup relations in recreational fisheries governance.

Complex social-ecological systems (SES), especially systems with common pool resources, often exhibit system dynamics characterized by emergence, where system properties cannot be fully explained by input variables. This causes challenges when it comes to explaining resource use problems because problem dynamics can differ from case to case despite similar input variables. Archetype analysis with its focus on identifying building blocks of nature-society relations might provide a means to tackle emergence and complexity in the analysis of resource use problems in SES. Using data from inter-and transdisciplinary research investigating comparative case studies on common village pasture management in the Caucasus region, we use the archetype approach with a focus on system archetypes that place particular emphasis on recognizing recurrent structures and internal dynamics. We apply three system archetypes, the Tragedy of the Commons, Shifting the Burden, and Success to the Successful, to different aspects of interlinked management problems that occur repeatedly in the case study data. Using SES variables characterizing the cases, we discuss variable combinations that may trigger specific dynamics. Moreover, we explore interlinkages between archetypical problems and discuss possible solutions based on self-governance. We find that the archetype approach with a focus on system archetypes resulted in consistent explanations of problem dynamics leading to important additional insights into root causes and internal archetypical dynamics compared with existing knowledge. Regarding problem solutions and policy recommendations, we show that viewing archetypical problems as interlinked in their actual case-study context leads to different recommendations than when each archetype is viewed on its own.
