Linking participatory approach and rapid appraisal methods to select potential innovations in collective irrigation systems Agric. Water Manag. (IF 5.9) Pub Date : 2024-05-24 Maria do Rosário Cameira, Isabel Rodrigo, Andreia Garção, Manuela Neves, Antónia Ferreira, Paula Paredes
This paper presents a novel approach that integrates participatory methods and a rapid appraisal process to identify constraints and select potentially innovative solutions aimed at improving water and energy use efficiency at different levels in collective irrigation systems. First, a set of quantitative performance indicators is calculated, allowing the identification of the main problems. The study

Meteorological and biophysical controls of evapotranspiration in tropical grazed pasture under rainfed conditions Agric. Water Manag. (IF 5.9) Pub Date : 2024-05-24 Israel W.H. da Silva, Thiago V. Marques, Stela A. Urbano, Keila R. Mendes, Ane Caroline C.F. Oliveira, Fábio da S. Nascimento, Leonardo Fiusa de Morais, Waldeir dos S. Pereira, Pedro R. Mutti, João Virgínio Emerenciano Neto, José Romualdo de S. Lima, Pablo E.S. Oliveira, Gabriel B. Costa, Cláudio M. Santos e Silva, Bergson G. Bezerra
Evapotranspiration (ET) is the main driver of the energy balance partitioning and influences hydrological and carbon cycles at global, regional and local scales. Furthermore, it is the main requirement for developing strategies to improve water use in agriculture. It is known that there is a close relationship between ET and rainfall, especially in tropical environments. Thus, the main goal of this

Effects of biodegradable film types and drip irrigation amounts on maize growth and field carbon sequestration in arid northwest China Agric. Water Manag. (IF 5.9) Pub Date : 2024-05-23 Yonghui Liang, Yue Wen, Yu Meng, Haiqiang Li, Libing Song, Jinzhu Zhang, Zhanli Ma, Yue Han, Zhenhua Wang
Biodegradable film (BF), as a superior substitute for traditional polyethylene film (PF), has experienced a consistent increase in China. However, a significant research gap persists regarding the utilization of BF in assessing farmland carbon balance. This experiment examined the responses of maize growth, yield, irrigation water productivity (IWP), CO emissions, and field net carbon sequestration

Water conservation and saving technologies for irrigation. A structured literature review of econometric studies on the determinants of adoption Agric. Water Manag. (IF 5.9) Pub Date : 2024-05-23 Andrea Pronti, Sabrina Auci, Julio Berbel
Water Conservation and Saving Technologies (WCSTs) can contribute to reduce the pressure on water resources from agricultural activities. A significant strand of literature on agricultural and innovation economics has explored the main drivers behind the adoption of WCSTs in agriculture, but due to the shortage of data most studies are based on survey analyses focusing on a specific case study. Therefore

Supplemental irrigation mitigates yield loss of maize through reducing canopy temperature under heat stress Agric. Water Manag. (IF 5.9) Pub Date : 2024-05-23 Huajian Jian, Zhen Gao, Yingying Guo, Xinyan Xu, Xiaoyu Li, Meijia Yu, Guangzhou Liu, Dahong Bian, Yanhong Cui, Xiong Du
Due to global warming, high temperature stress severely impacts maize growth and development, especially during the early filling stage. Supplemental irrigation is an effective measure to mitigate high temperature stress in maize. However, the underlying mechanism for alleviating transient high temperature stress during the early grain-filling stage is still unclear. A two-year field experiment involving
