In this study, we focus on water quality as a vehicle to illustrate the role that the water, energy, and food (WEF) Nexus perspective may have in promoting ecosystem services in agriculture. The mediation of water quality by terrestrial systems is a key ecosystem service for a range of actors (municipalities, fishers, industries, and energy providers) and is reshaped radically by agricultural activity. To address these impacts, many programs exist to promote improved land-use practices in agriculture; however, where these practices incur a cost or other burden to the farmer, adoption can be low unless some form of incentive is provided (as in a payment for ecosystem services (PES) program). Provision of such incentives can be a challenge to sustain in the long term, if there is not a clear beneficiary or other actor willing to provide them. Successfully closing the loop between impacts and incentives often requires identifying a measurable and valuable service with a clear central beneficiary that is impacted by the summative effects of the diffuse agricultural practices across the landscape. Drawing on cases from our own research, we demonstrate how the WEF Nexus perspective—by integrating non-point-source agricultural problems under well-defined energy issues—can highlight central beneficiaries of improved agricultural practice, where none may have existed otherwise.

Sustainable Development Goals offer an opportunity to improve human well-being while conserving natural resources. Ecosystem services highlight human well-being benefits ecosystems, including agricultural ecosystems, provides. Whereas agricultural systems produce the majority of our food, they drive significant environmental degradation. This tension between development and environmental conservation objectives is not an immutable outcome as agricultural systems are simultaneously dependents, and providers of ecosystem services. Recognizing this duality allows integration of environmental and development objectives and leverages agricultural ecosystem services for achieving sustainability targets. We propose a framework to operationalize ecosystem services and resilience-based interventions in agricultural landscapes and call for renewed efforts to apply resilience-based approaches to landscape management challenges and for refocusing ecosystem service research on human well-being outcomes.

The agricultural water resource carrying capacity (AWRCC) is affected by climate change now as never before. However, it is still unclear how the AWRCC in high latitudes responses to climate change. In this study, spatiotemporal changes in climatic factors and AWRCC during the crop growing season from 1961 to 2014 in the Nenjiang River Basin (NRB), a high-latitude basin in China, were identified via multivariate statistical analysis. Meanwhile, the impact of climatic factors on AWRCC was analyzed by using cross-wavelet approaches and Pearson correlational analysis. The results showed that temperature has followed an increasing trend, especially the lowest temperature during crop growing season, with a trend of 0.57 /10a in the local region. There was no obvious change trend for precipitation, but the interannual change was large. The drought index increased first and then decreased, which was consistent with the trend of the ET0. Different spatial distributions of water resource carrying for all crops in a region were shown with a variation range of 0.22–0.76 kg/m2 in the NRB. It is worth noting that AWRCC showed an increasing trend, especially in the past decade. Precipitation, ET0, and meteorological drought were all key driving factors affecting AWRCC. The correlation was significant between the crop planting proportion and AWRCC under climate change. Moreover, adjusting the planting proportion of wheat, soybean and rice, and increasing that of maize, would be conducive to improving the AWRCC and facilitating the synergistic development of agriculture and wetlands in NRB.

Wetlands are one of the most valuable natural resources on earth and play an important role in preserving biodiversity. However, due to economic development and human disturbances, many wetlands across the world have deteriorated and disappeared over the past several decades. By using remote sensing images and point of interest (POI) data, we proposed a knowledge-based raster mapping (KBRM)-based framework and implemented it in the assessment of wetland ecological conditions in Suzhou, China. Density maps of waterbodies, vegetation covers, imperviousness, roads, and POI values were derived and used as five ecological indicators that can represent the ecological conditions of wetlands. The KBRM approach was used to integrate these indicators into an overall rating and map wetland ecological conditions efficiently. Thus, spatial variations in wetland ecological conditions can be distinguished and represented in detail. Cross validation was conducted with water quality data at 15 field sampling sites. The validation results demonstrated that the overall wetland condition scores generated by our approach and the water quality index (WQI) values calculated from water quality data were strongly correlated. These findings confirm that our framework could be used to effectively map and evaluate spatial variations in wetland ecological conditions and provide more support for policy-making in wetland protection and management

With the continuous growth of the world's social economy and population, problems such as water shortage and water environment deterioration need to be solved urgently. Combining the emergy carrying capacity of water resources and the emergy ecological footprint method, the water security and sustainable development status of the typical city in the karst region (Anshun City) was evaluated, and the internal driving factors and optimization suggestions were discussed. The research results of water security in Anshun City show that: The water resources carrying capacity fluctuates greatly with rainfall and is generally in a low-level surplus state. The ecological pressure index and the sustainable utilization index show a downward trend. The pressure intensity of social and economic systems on water resources is increasing, and the sustainable development of water resources is not optimistic. Water resources security is mainly affected by natural ecological mechanisms centered on mountain systems, geological structures and hydrological systems, as well as social mechanisms centered on changes in population scale, land development and utilization, and urban development. In the future, the sustainable development of water resources can be promoted by changing the mode of economic development, optimizing the allocation of water resources, and protecting the ecological environment.
