Baiyangdian Wetland

River system network (RSN) connectivity is important to maintain the environmental and ecological functions of wetlands. Quantitative evaluation of connectivity can provide crucial support for efforts to improve wetland connectivity and to restore and protect wetland ecosystems. Most existing evaluation methods uniformly generalise RSN to form an undifferentiated RSN of edges and nodes that is taken as a whole to evaluate the connectivity. However, actual RSNs comprise rivers, canals, ditches, lakes, and ponds, which differ substantially in their structures, morphologies, and attributes. The mix of RSN elements therefore defines grades that give RSNs distinctive characteristics. Moreover, RSNs with different grades perform different ranges of environmental and ecological functions. The existing evaluation methods, which have some limitations, do not account for these characteristics. To account for these differences, we examined the grade characteristics and their impact on environmental and ecological functions. We established a grading system of RSN elements and a grading method of RSN, and constructed the structural connectivity evaluation indicator system for RSNs at different grades. On this basis, we propose a method for grading evaluation of RSN connectivity. We used China’s Baiyangdian Wetland to demonstrate the use of the system and validate the results. The proposed method provided an objective and accurate evaluation of RSN connectivity and clarified the differences in connectivity among RSNs with different grades, thereby providing improved guidance for the development and maintenance of the environmental and ecological functions of RSNs.

AbstractRecreation demand studies have traditionally utilized a two-step valuation method, estimating conditional recreation participation probabilities and then intensity of use decisions. These two steps of analysis are combined to estimate the use value of natural resource recreation sites. The purpose of this paper is to provide a method by which use value can be estimated solely from the participation decision. The one-step resource valuation method allows estimation of use values from coefficients of the logistic regression recreation participation equation. The benefits of the method are the reduced data and effort required to value natural resource areas.

The present investigation was undertaken to work out the economic performance and optimum cropping pattern based on alternative price scenarios in Arid-Western Plain Zone of Rajasthan state. In the present study, the unit-level cost of cultivation data of various crops for the triennium ending year 2013-14 which were collected from “Comprehensive Scheme to Study the Cost of Cultivation of Principal Crops in Rajasthan state. The performance of different crops was assessed by calculating net returns under three alternative price scenarios i.e. (i) Market prices (MP) (ii) Economic prices (EP) and (iii) Net income based on natural resource valuation technique (NRV). This study has considered subsidy as a cost to society. Similarly green house gas emissions from the crops have been taken as cost to the society and nitrogen fixation by leguminous crops have been taken as gain to the society. Results from the study shows that groundnut-barley combination of crop sequence was found the most remunerative in economic return generated over the year of `59418 per hectare followed by groundnut-vegetables (`53930/ha) and groundnut-gram (`52879/ha) combinations. Net gain to the farmers based on the alternative price scenarios viz. market, economic and natural resource valuation prices were estimated as `114.38 lakh, `114.45 lakh and `138.82 lakh, respectively. The overall gain to society has increased at economic prices by `49.39 lakh whereas it was decreased by `93.24 lakh at natural resource valuation due to the lack of cultivation of legume crops. The optimal plan is suggested that more area under cultivation of legume crops like groundnut, clusterbean and gram because of they are less water intensive and more environment friendly and thus have a positive impact on natural resource valuation with the existing water availability.

Baiyangdian Wetland

<p>Hydrological connectivity is a critical determinant of wetland functions and ecosystems by controlling the movement of biogeochemical elements within wetlands and the flow of water between their hydrological units. Hydrological barriers exist when this connectivity is impaired, either by man-made infrastructure, agriculture developments, or naturally restricted by soil and ground composition. Determining hydrological barriers in wetlands is challenging due to the costs of high-resolution and large-scale monitoring, but radar observations can become a useful tool for such task. We here use an Interferometric Synthetic Aperture Radar (InSAR) to identify hydrological barriers in several iconic wetlands worldwide, with particular focus on the Baiyangdian wetland system in Northern China. For the first, we use Sentinel 1A and 1B data covering the period 2016-2019, while for the rest we rely on ALOS PALSAR data. We calculated profiles of water level change across hydrological transects showing high coherence and visualized them in maps. For instance, in the case of the Baiyangdian wetland, we find that of the 70 transects studied, 11% of all transects are permanently disconnected by hydrological barriers across all interferograms and 58% of the transects are conditionally disconnected. The occurrence of hydrological barriers varies between wetlands, with permanent barriers more related to ditches, infrastructure and the specific wetland landscape, and conditional barriers more to low water levels during dry seasons. This study highlights the potential of the application of wetland InSAR to determine hydrological barriers for wetland management and restoration.</p>
