ABSTRACT
The threats to human health caused by climate change have become a global public health issue. However, at present, most studies regarding the health-related mechanisms of climate change are limited to biological mechanisms, and most of these mechanisms are not totally clear. In this special column: Mechanisms underlying human health effects of climate change, we offered several papers which investigated the effects of different meteorological factors (temperature and rainfall) on various health outcomes (preterm birth, death, diarrhea, infectious diseases, etc.), and also elaborated associated potential biological mechanisms, vulnerability mechanisms, social driving process and transmission dynamics mechanisms. These studies can deepen our understanding of the health effects of climate change, provide references to make targeted adaptative measures, and also provide scientific and technological supports for improving ability to address the health risks of climate change in China.
ABSTRACT
This study assessed the potential impacts of climate change on potato production in the United Kingdom. Climate change actions are becoming a nightmare for growers worldwide, and the British potato industry is not an exception. Extreme weather conditions were experienced in 2006, 2012, and 2018, respectively. Thus, this study identified the future climate risk associated with major potato producing regions in the UK using the recent climate projection weather data (UKCP18) based on RCP 8.5. In total, the study considered seven (7) regions with a minimum average of 3000 hectares of potato planted area in the past five years. Findings showed that drought, high temperatures, and prolonged precipitation caused significant yield and quality loss in the past, with a likelihood of causing a more harmful impact in the future. The analysis revealed a hotter (Tmax ≥ 25°C, Tmin ≥ 15°C) and drier (1-1.5 mm day-1) summer most especially in the EE, EM, SW, WM, and YH as well as a warmer (Tmax& Tmin 6-10°C) and wetter winter (5 mm day-1 on average) in Scotland and North West England respectively. Future climate is predicted to hinder land preparation and harvesting operation in the Northern regions while the EE, EM, SW, WM, and YH would be faced with drought, with irrigation and water demand increasing by 20-30% as evapotranspiration also increases by 20-30% in 2050-2080. Irrigated potatoes are predicted to double its current spatial coverage in the future. The study identified suitable adaptation measures and strategies required to reduce the impacts of climate change on the British potato industry.
ABSTRACT
El presente trabajo parte de una breve fundamentación teórica que soporta una estructura metodológica tendiente al cálculo de cambio climático, el estudio de la variabilidad climática en el territorio de las cuencas de los ríos Zulia y Pamplonita en Norte de Santander y la identificación inicial de medidas potenciales de adaptación al cambio climático y la variabilidad climática. En su desarrollo se identificaron y espacializaron las tendencias de cambio climático y las alteraciones más probables de los fenómenos de variabilidad climática asociados al ciclo ENSO6 para el período 1981-2010 en las cuencas objeto de estudio. Los resultados obtenidos muestran que la temperatura media ha cambiado entre 0,1 y 0,4ºC por década en las cuencas, la precipitación ha aumentado de 0 a 250 mm/década y los ciclos ENSO generan alteraciones en la variabilidad climática de las cuencas de manera diferenciada a nivel estacional e interanual, especialmente en los trimestres Dic-Ene-Feb, Jun-Jul-Ago y Sep-Oct-Nov.
This work is based on a brief theoretical foundation that supports a methodological structure aimed at the calculations of climate change, the study of climate variability in the territory of the basins of the Zulia and Pamplonita rivers in Norte de Santander and the initial identification of potential measures of adaptation to climate change and climate variability..In its development, the climate change trends and the most likely alterations of the climate variability phenomena associated with the ENSO cycle for the period 1981-2010 in the basins of the object of study were identified and spatialized. The results obtained show that the average temperature has changed between 0.1 and 0.4°C per decade in the basins, precipitation has increased from 0 to 250 mm/decade and the ENSO cycles generate alterations in the climate variability of the basins on a differentiated manner on a seasonal and year-on-year level, especially in the Dec-Jan-Feb, Jun-Jul-Aug and Sep-Oct-Nov quarters.
