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.

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 km3/a in 2000, 17.2 km3/a in 2005, and 15 km3/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.
