Water, energy, and food (WEF) related sectors are important to support people’s life in a region. Resource evaluation is one of the stages in resource management to ensure that the existence of those sectors is provided sustainably. The assessment of the agglomeration level and growth of each sector in economic development can give better insights for local stakeholders either government bodies or private firms to improve sustainable management of these sectors. The objectives of this paper are to portray the agglomeration level and recent growth of WEF related sectors in local regions in Indonesia, and to determine possible sustainable development strategies. The location quotient (LQ) and competitive position (CP) analysis methods are employed in this regard. By analysing Gross Regional Domestic Product (GRDP) between 2000 and 2015, basic and non-basic sectors have been determined. Results show that the general characteristics of WEF related sectors in this region can be distinguished clearly based on its main economic development focus. Results show recent growth in WEF sectors locally, from which possible strategies for future sustainable development are formulated that could be considered in the evaluation and planning process. This approach can be expected to assist local government and stakeholders in undertaking preliminary evaluation, in particular the availability of WEF resources, ensuring that development meets local and national sustainable development targets.

The Songhua River is the largest river in northeastern China; the river’s water quality is one of the most important factors that influence regional ecological health and food safety in northeastern China and even the downstream of the Heilong River in Russia. In recent years, the Chinese government implemented several water resource protection policies to improve the river’s water quality. In order to evaluate the influence of the new policies on the water quality in the Songhua River, water quality data from 2006 to 2015 were collected monthly from the nine sites along the mainstream of the Songhua River. Results show that the water quality in the Songhua River could be divided into two groups during the last 10 years. Before 2010, water quality in the Songhua River was primarily influenced by regional human activities. Industries were the major pollutant sources in the upstream of the Songhua River. After several new policies were implemented by the local government in 2010, water quality in the Songhua River improved. As a result, the biodiversity of fish and ecological health in the Songhua River improved.

Christian Stein, Claudia Pahl-Wostl, Jennie Barron, 'Towards a relational understanding of the water-energy-food nexus: an analysis of embeddedness and governance in the Upper Blue Nile region of Ethiopia', Environmental Science & Policy, vol. 90, pp.173-182, Elsevier BV, 2018 | Given the need for transformative changes towards more sustainable, integrated management of water, energy and food systems, the water-energy-food nexus concept seems highly relevant. However, while intuitively compelling, the nexus has also been criticized for abstracting and thereby dis-embedding the collaboration processes through which further integration could be achieved. There is a lack of empirical analysis and contextsensitive understanding, of the opportunities and constraints of, collaboration and cross-sector coordination, as faced by actors governing interconnected water, energy and food systems. In this paper we analyse how actors involved in the governance of water, energy and food systems are embedded in social networks, and discuss how that embeddedness shapes collaboration and coordination processes that are relevant for addressing interconnected sustainability challenges. Drawing on the notion of problemsheds, we delineate an analytical space that captures the interactions between water, energy and food systems and the actors influencing them in the Upper Blue Nile of Ethiopia. Our empirical data suggest that the claim that actors from different sectors are disconnected from each other is overly simplistic. The ways in which actors are embedded in hierarchical structures may help to explain why coordination challenges persist, despite the presence of cross-sectoral linkages among them
