“…The decrease in groundwater level is especially alarming near Beijing in Hebei Province, which covers most of the Hai River Basin, one of nine major river basins in China [3]. Over-pumping in this region has resulted in serious environmental consequences such as land subsidence, intrusion of saline water into freshwater aquifers and deterioration of ecosystems [4][5][6]. Increasing water scarcity is particularly challenging to the agricultural sector.…”

This paper examines the impacts of off-farm employment on irrigation water efficiency (IWE) with a set of household level data collected in Hebei Province in North China. A major finding is that households with higher shares of laborers working off-farm locally seem to achieve higher IWEs. The effect of local off-farm employment is greater among those households that have made more efforts to use furrow irrigation. We also find that households with higher shares of elderly laborers and those with larger land holding are associated with lower IWEs. Households with better soil quality and those that pump from deeper wells are associated with higher IWEs.

“…Consequently, deltaic systems have been amply used to document short-term natural-and human-driven processes responsible for coastline changes (e.g., Fan et al, 2006;Xeidakis et al, 2007;El Banna and Frihy, 2009;Sabatier et al, 2009;Simeoni and Corbau, 2009). Among the former, the development of deltaic units may be influenced by short-term climate change inducing precipitation changes, rapid sea-level changes, autocyclical processes such as channel avulsion and delta-lobe switching, and tectonism (Mateo and Siringan, 2007).…”

“…Furthermore, several anthropogenic activities can also significantly impact and control the morphology and evolutionary behavior of the different components of fluvio-deltaic systems (Correggiari et al, 2005). Anthropogenic activities leading to considerable coastline changes include channelization/channel deviation, dredging, damming, and deforestation, among others (Fan et al, 2006;Simeoni and Corbau, 2009). However, the response of deltaic systems to natural or human-induced changes is mainly controlled by changes in the sediment supply reaching the coastal domain (Mateo and Siringan, 2007).…”

“…However, with the sharp decrease in sediment supply in recently decades due to the human activities on the upper and middle reaches of the river, the morphological process of the delta has switched from predominately depositional to predominately erosional with marine hydrodynamic processes (e.g. waves and currents) playing an increasingly important role (Li et al 2000;Chu et al 2006;Fan et al 2006;Shi et al 2007).…”

The subaerial delta of the Yellow River has undergone a notable reshaping process with drastic changes in erosion and accretion patterns both temporally and spatially. These morphological changes not only have significant impact on the long-term evolution of delta but also pose severe threat to the existing infrastructures adjacent to the eroding delta lobe. This paper presents a data-based study of waves, currents, sediments and subaqueous bedforms including the application of Principal Component Analysis (PCA) to the measured coastal profiles in order to understand qualitative and quantitative processes that are responsible for the observed changes. The results demonstrated that the Yellow River Delta has recently been dominated by recession process due to the reduced sediment supply from the Yellow River in the recent decades. A critical threshold of river sediment discharge was formulated and used to explain the observed morphodynamic processes. It was found that the coast of the Yellow River Delta could be broadly divided into three geomorphic zones: the area near abandoned delta, the estuarine area, and Laizhou Bay. At the nearshore zone of the abandoned delta, waves are the main agent for bed erosion and sediments suspension. The tidal current is effective in transporting suspended sediments and exerts the main control on the depths of the erosion-accretion balance zone on the coastal profiles. The area near the present estuary has seen rapid deposition with the progradation rate being governed by the relative intensity of fluvial and marine processes while the coasts in Laizhou Bay are stable and the particular characteristics of the tidal current field prevent the sediments supplied by the Yellow River from reaching this area.
