TLDR
In this article, a scenario for future agrichemical use and attendant environmental problems is drawn through a review of the main climate change-mediated drivers for agrichemicals use, with a focus on land-use changes and changes in pest and disease patterns.Abstract:
Since the implementation of economic reforms in 1986, the Mekong Delta has experienced an extensive transformation process in its agricultural sector. This transformation has been characterized by agricultural intensification, the enhanced use of agrichemicals (fertilizer, pesticides), and emerging concerns for human health and the environment. The predicted impacts of climate change such as sea level rise, greater seasonal variability in precipitation and river flows, and elevated temperature and CO2 concentration will all likely also influence the agricultural landscape and thus agrichemical use. Against the background of the anticipated climate change impacts in the Mekong Delta, this chapter aims to draw a scenario for future agrichemical use and attendant environmental problems. This scenario is achieved through a review of the main climate change-mediated drivers for agrichemical use, with a focus on land-use changes and changes in pest and disease patterns. In addition, the chapter identifies possible adaptation measures that may be implemented by the agricultural sector in the Mekong Delta and explores the potential environmental effects of these adaptation strategies.read more

Pesticide management and their residues in sediments and surface and drinking water in the Mekong Delta, Vietnam.
TL;DR: It is shown that household level pesticide management remains suboptimal in the Mekong Delta and co-occurrence of several pesticides in the samples indicate a considerable chronic exposure of biota and humans to pesticides.

Climate and Environmental Change in River Deltas Globally: Expected Impacts, Resilience, and Adaptation
TL;DR: In this article, the most common environmental impacts of society's economic development expressed via agricultural intensification, increasing urban sprawl, industrial activity, and infrastructure expansion in deltas, as well as the climate change and sea level rise (SLR) related challenges that threaten delta development in many countries.

Use of pesticides and attitude to pest management strategies among rice and rice-fish farmers intheMekong Delta, Vietnam
Håkan Berg,Nguyen Thanh Tam +1 more
TL;DR: A temporal trend for more selective use of pesticides and an increased awareness among non-IPM farmers of the negative side effects of pesticide use is indicated.

Association between climate factors and diarrhoea in a Mekong Delta area.
Dung Phung,Cunrui Huang,Cunrui Huang,Shannon Rutherford,Cordia Chu,Xiaoming Wang,Minh Nguyen,Nga Huy Nguyen,Cuong Do Manh,Trung Hieu Nguyen +9 more
TL;DR: The results indicated that the diarrhoea incidence peaked within the period August–October annually, and climate change will have important implications for residential health in Mekong Delta region.

Pesticides and antibiotics in permanent rice, alternating rice-shrimp and permanent shrimp systems of the coastal Mekong Delta, Vietnam
Gianna Braun,Melanie Braun,Jens Kruse,Wulf Amelung,Fabrice G. Renaud,Chau Minh Khoi,M.V. Duong,Zita Sebesvari +7 more
TL;DR: Overall, farmers were most conscious of agrochemical use in alternating rice-shrimp systems to prevent harm to shrimps, which was reflected in overall lower concentrations of agrachemicals when compared to rice systems.

Climate Change 2001: Impacts, Adaptation, and Vulnerability
TL;DR: In this paper, the authors set the stage for impact, adaptation, and vulnerability assessment of climate change in the context of sustainable development and equity, and developed and applied scenarios in Climate Change Impact, Adaptation, and Vulnerability Assessment.

Climate change 2007 : impacts, adaptation and vulnerability
TL;DR: In this paper, the authors present a cross-chapter case study on climate change and sustainability in natural and managed systems and assess key vulnerabilities and the risk from climate change, and assess adaptation practices, options, constraints and capacity.

Crop losses to pests
TL;DR: Despite a clear increase in pesticide use, crop losses have not significantly decreased during the last 40 years, however, pesticide use has enabled farmers to modify production systems and to increase crop productivity without sustaining the higher losses likely to occur from an increased susceptibility to the damaging effect of pests.

Rice yields decline with higher night temperature from global warming

TL;DR: This report provides a direct evidence of decreased rice yields from increased nighttime temperature associated with global warming and a close linkage between rice grain yield and mean minimum temperature during the dry cropping season.

Historical Warnings of Future Food Insecurity with Unprecedented Seasonal Heat
TL;DR: Observational data and output from 23 global climate models show a high probability that growing season temperatures in the tropics and subtropics by the end of the 21st century will exceed the most extreme seasonal temperatures recorded from 1900 to 2006.
