Abstract This study aimed to evaluate household's willingness to pay (WTOP) for irrigation water use (IWU) per timad (0.25 ha) of the irrigable land per year and to analyze determinants of WTOP for IWU at individual households based on the contingent valuation method (CVM).

Abstract The focus on irrigation infrastructure development in countries like India, including a significant allocation of the government's budget, highlights the importance of achieving a high benefit–cost ratio for these projects. However, past reviews have revealed instances where irrigation projects yielded low benefits.

Geospatial data and web based tools for managing irrigation infrastructure expansion projects
Abstract Improving irrigation infrastructure is important for sustaining food security in developing countries like India. The irrigation potential of a system is estimated at the planning phase using conventional approaches. A mismatch in the irrigation potential planned to be created and the land suitable for cultivation can lead to a gap in the ...

SE‐Former: Incorporating sentence embeddings into Transformer for low‐resource NMT
To leverage SimCSE for low‐resource NMT, in this work incorporating sentence embeddings from SimCSE into the Transformer network is explored and SE‐Former model is proposed. In this model an embed‐fusion module is designed to utilize the output of SimCSE for NMT.

Hydro‐Insurgency: Weaponization of Water Resources and Infrastructure in Northeast Syria
ABSTRACT This article examines the strategic weaponization of water resources by Turkey‐backed armed groups in Northeast Syria (NES) within the broader context of the Syrian civil war. As the conflict evolved, water infrastructure—dams, rivers, and irrigation systems—became central to warfare, governance, and foreign agendas. The article introduces the

ABSTRACT Groundwater governance is complex due to several externalities associated with groundwater being an invisible natural resource tied to the land with millions of extractors and limited means of exclusion. The paper traces the evolution of groundwater irrigation in India and the corresponding change in groundwater laws and policies to address ...

以水稻、高粱和玉米为研究对象,考察了微囊藻毒素对受试作物的毒性差异,研究了不同浓度MC对萌发及萌发初期生长发育的影响,不同灌溉时期对受试作物生长发育的影响,检测指标包括发芽率、株高、鲜重、叶绿素、根系活力等。结果表明,受试作物对微囊藻毒素毒性并不一致,水稻发芽率受到明显抑制,高粱发芽率基本不受影响,玉米出现了低浓度促进、高浓度抑制的现象;MC对水滔、高粱和玉米的光合作用、株高和鲜重没有抑制作用,反而有一定的促进效果;不同灌溉时间条件下的研究结果表明,萌发前对高粱和玉米染毒会明显抑制植株根系活力 ...

通过室内土柱模拟试验的方法,研究了再生水灌溉对土壤理化性质的影响。结果表明:再生水灌溉对土壤扩散率和饱和导水率的影响与连续灌溉再生水的次数有关,短时间灌溉有降低的作用,但随着灌溉次数的增加,土壤扩散率和饱和导水率有增加的趋势;同时,随着灌溉次数的增加,土壤pH值降低,土壤有机质和全盐量增加;土壤溶液中各离子浓度有显著变化。灌溉5次之后,除0~10cm土层全盐量为0.107%外,其他各层均低于0.1%的限度;0~10,10~20,30~40cm土层的ESP均在5%~10%范围之内,20 ...

明清时期跨区域农学知识传播方式的个案研究——以畿辅地区的水稻推广为例 [PDF]
由于交通不便与地理空间的隔阂,古代跨区域农学知识的传播方式很难被观察到,而明清时期畿辅地区水稻种植的推广由于保存了大量的原始文献,可视为考察长时段跨区域农业知识传播的一个经典案例。本文详细分析了明清畿辅地区水稻推广中的技术传播主体及传播方式 ...
