Abstract

The paper provides new evidence of the effect of temperature and precipitation on crop profit of farmers applying different farming systems across different seasons as well as geographical regions in Vietnam for the period 2004–2016. The result finds that the effect of fluctuation in temperature and rainfall on the crop profit of farmers is not uniform across the three regions (North, Central and South) and also considerable variation across rain‐fed and irrigated farms. For the rain‐fed farming system, (i) rainfall in the dry season has a nonlinearly (⋂) association with the profit, but rainfall in the rainy season has no effect, and (ii) dry season temperature and rainy season temperature have, respectively, ⋂‐shaped and U‐shaped relationship with the profit. For the irrigated farming systems, the temperatures in the dry season and rainy season have a U‐shaped relationship with the profit. The findings show that the irrigated farming systems have been effective in the long term in the face of climate change. Therefore, in preparation for adaptation to climate change, the Vietnamese agricultural sector needs a complete irrigation system at both farm and regional levels.

气候因素对越南雨养和灌溉农户农业收入的影响

本文提供了2004-2016年期间越南不同季节和地理区域采用不同耕作制度的农民的温度和降水对作物利润影响的新证据。结果发现，温度和降雨量的波动对农民作物利润的影响在三个地区(北部、中部和南部)是不均匀的，在雨养和灌溉农场之间也有很大的差异。对于雨养耕作系统，(1)旱季降雨与利润呈非线性()相关，但雨季降雨对利润没有影响;(2)旱季温度和雨季温度与利润分别呈‐形和U‐形关系。对于灌溉农业系统，旱季和雨季的温度与利润呈U型关系。研究结果表明，从长远来看，面对气候变化，灌溉农业系统是有效的。因此，为了准备适应气候变化，越南农业部门需要在农场和地区层面建立一个完整的灌溉系统。

期刊介绍： Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including: -Water and wastewater treatment for agricultural, municipal and industrial applications -Sludge treatment including processing, storage and management -Water recycling -Urban and stormwater management -Integrated water management strategies -Water infrastructure and distribution -Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
