In agriculture, balancing water use and retention is an issue dealt with in most regions and for many crops. In this study, we suggest agricultural water equilibrium (AWE) as a new concept that can facilitate a spatially explicit management of agricultural water. This concept is based on the principle of supply and demand of agricultural water, where the virtual water content of crops (VWC) can be defined as the demand, and cropland water budget (CWB) as the supply. For assessing the AWE of the Korean Peninsula, we quantified the CWB based on the hydrological cycle and the VWC of rice, a key crop in the Peninsula. Five factors, namely crop yield, growing season evapotranspiration, annual evapotranspiration, runoff, and annual precipitation, were used to assess the AWE, of which the first four were estimated using the spatially explicit large-scale crop model, Geographical Information System (GIS)-based Environmental Policy Integrated Climate (GEPIC). The CWB and VWC were calculated for a period of three decades, and the AWE was computed by deducting the VWC from the CWB. Our results show a latitudinal difference across the Korean Peninsula. On analyzing the AWE of the major river basins, we found most basins in North Korea showed very low values inferring unsustainable overconsumption of water. The latitudinal difference in AWE is a reflectance of the latitudinal changes in the VWC and CWB. This can be explained by decoupling the demand and supply of agricultural water. Although the AWE values presented in this study were not absolute, the values were sufficient to explain the latitudinal change, and the demand and supply of agricultural water, and establish the usefulness of the indicator.

Increasing anthropogenic activities have significantly altered ecosystems in arid oasis regions. Estimating the impact on a wide range of ecosystem services is important for decision making and the sustainable development of these regions. This study analyzed time-series Landsat data to determine the influences of oasis land-use changes on the ecosystem services in the Kashgar region in Northwest China. The following results were found. The total value of the ecosystem services in the Kashgar region were approximately $10,845.3, $11,218.6, $10,291.7, and $10,127.3 million in 1986, 1996, 2005, and 2015, respectively. The water supply, waste treatment, biodiversity protection, and recreation and cultural services were the four ecosystem services with the highest service value, contributing 77.05% of the total ecosystem services. The combined contribution rate of food production and raw material value was only about 4.02%, relatively small. The sensitivity analysis indicated that the estimated total ecosystem service value (ESV) for this study area was relatively inelastic with respect to the value coefficients. The findings of this study will be crucial for maintaining the stability and sustainable development of the oasis region, where socio-economic development and the integrity of the natural ecosystem complement each other. Furthermore, the results provide a scientific basis for decision makers in land use management, and provide a reference for researchers in the Northwest China. Full article

Private standards, including ecolabels, have been posed as a governance solution for the global fisheries crisis. The conventional logic is that ecolabels meet consumer demand for certified “sustainable” seafood, with “good” players rewarded with price premiums or market share and “bad” players punished by reduced sales. Empirically, however, in the markets where ecolabeling has taken hold, retailers and brands—rather than consumers—are demanding sustainable sourcing, to build and protect their reputation. The aim of this paper is to devise a more accurate logic for understanding the sustainable seafood movement, using a qualitative literature review and reflection on our previous research. We find that replacing the consumer-driven logic with a retailer/brand-driven logic does not go far enough in making research into the sustainable seafood movement more useful. Governance is a “concert” and cannot be adequately explained through individual actor groups. We propose a new logic going beyond consumer- or retailer/brand-driven models, and call on researchers to build on the partial pictures given by studies on prices and willingness-to-pay, investigating more fully the motivations of actors in the sustainable seafood movement, and considering audience beyond the direct consumption of the product in question.

Integrated approaches to natural resource management are often undermined by fundamental governance weaknesses. We studied governance of a forest landscape in East Lombok, Indonesia. Forest Management Units (Kesatuan Pengelolaan Hutan or KPH) are an institutional mechanism used in Indonesia for coordinating the management of competing sectors in forest landscapes, balancing the interests of government, business, and civil society. Previous reviews of KPHs indicate they are not delivering their potential benefits due to an uncertain legal mandate and inadequate resources. We utilized participatory methods with a broad range of stakeholders in East Lombok to examine how KPHs might improve institutional arrangements to better meet forest landscape goals. We find that KPHs are primarily limited by insufficient integration with other actors in the landscape. Thus, strengthened engagement with other institutions, as well as civil society, is required. Although new governance arrangements that allow for institutional collaboration and community engagement are needed in the long term, there are steps that the East Lombok KPH can take now. Coordinating institutional commitments and engaging civil society to reconcile power asymmetries and build consensus can help promote sustainable outcomes. Our study concludes that improved multi-level, polycentric governance arrangements between government, NGOs, the private sector, and civil society are required to achieve sustainable landscapes in Lombok. The lessons from Lombok can inform forest landscape governance improvements throughout Indonesia and the tropics. Full article

The purpose of the present research was to analyze the available data on river restoration projects in Europe. As the framework of our study, we conducted a structured international survey. We asked selected entities and experts from among those responsible for river restoration in European countries about the details and costs of European Union river restoration projects. We examined 119 river restoration projects that were implemented in Europe between 1989 and 2016; during the collection of data, some of the projects were still ongoing. Based upon the collected data we observed that the number of river restoration projects has been increasing since 1989, which expresses society’s growing interest in improving the quality of aquatic environments. We revealed that 56% of these European river restoration projects have been implemented by dedicated entities and stakeholders, not as part of any structured, larger-scale river restoration policy. This indicates that most European countries do not have integrated plans for river restoration. Our analysis showed that 52% of the projects analyzed have been designed and implemented without the participation of local stakeholders. It also showed that the budgets for river restoration projects did not differ significantly across various time horizons from 1989 to 2016. In our study, the average cost of restoring 1 ha of an European river was 310,000 euros (EUR). Considering these projects’ permanent assets and including their amortization, we calculated the average unit price of a river restoration’s value in terms of ecosystem meta-service to be 7757 EUR·ha−1·year−1.

The emissions of carbon dioxide generated by urban traffic is generally reflected by urban size. In order to discuss the traffic volume generated in developed buildings and road crossings in a single urban block, with the metropolitan area in Taichung, Taiwan as an example, this study calculates the mutual relationship between the carbon dioxide generated by the traffic volume and building development scale, in order to research energy consumption and relevance. In this research, the entire-day traffic volume of an important road crossing is subject to statistical analysis to obtain the prediction formula of total passenger car units in the main road crossing within 24 h. Then, the total CO2 emissions generated by the traffic volume in the entire year is calculated according to the investigation data of peak traffic hours within 16 blocks and the influential factors of the development scale of 95 buildings are counted. Finally, this research found that there is a passenger car unit of 4.72 generated in each square meter of land in the urban block every day, 0.99 in each square meter of floor area in the building and the average annual total CO2 emissions of each passenger car unit is 41.4 kgCO2/yr. In addition, the basic information of an integrated road system and traffic volume is used to present a readable urban traffic hot map, which can calculate a distribution map of passenger car units within one day in Taichung. This research unit can be used to forecast the development scale of various buildings in future urban blocks, in order to provide an effective approach to estimate the carbon dioxide generated by the traffic volume.
