“…For each crop, the ET and NIR estimates obtained using meteorological data across weather stations were not significantly different between the two 24-year periods. Taking into account the predictions for increased temperature and decreased precipitation in the region (Xoplaki et al 2004;Mizyed 2009;Milano et al 2012) and in Cyprus in particular (Price et al 1999;Pashiardis & Michaelides 2008;Giannakopoulos et al 2010), as well as the increased evaporation and ET predicted by a number of regional climate models (Giorgi & Lionello 2008;Lovelli et al 2010;Tanasijevic et al 2014), the present results could significantly assist decisions on future water management measures.

SUMMARYDiminishing irrigation water availability and increased crop evapotranspiration (ET) have already been shown to pose threats to agricultural productivity. The aim of the current study was to estimate the values and trends of both ET and net irrigation requirements (NIR) of those crops consuming most water due to the size of their cultivated area (citrus and potatoes) in a water-scarce region with typical Mediterranean climate, such as Cyprus, analyse possible spatial and temporal variations of these parameters, and discuss implications of this analysis on agricultural water conservation. A linear regression analysis of ET and NIR values of potatoes and citrus during recent decades in their four main cultivated areas uncovered both increasing and decreasing trends for these parameters. Overall, however, the results did not show any change in irrigation water demands for these crops during recent years. In accordance with this outcome, average ET and NIR values of the majority of cultivated crops on the island showed no statistically significant differences between the periods 1976–2000 and 1990–2014. Conversely, this was not the case when data were analysed within each weather station across crops. It is suggested, therefore, that agricultural water resource management schemes should not be focused merely on a regional analysis of changes but that emphasis should be given to site-specific values and trends of ET and NIR estimations, ultimately serving the conservation of agricultural water.

“…The climate data restrictions result in local-scale studies which are limited to the use of point-data series. More studies can be found in the literature for the western part of our study region (Kostopoulou and Jones, 2005;Giannakopoulos et al, 2010;Kuglitsch et al, 2010;Hadjinicolaou et al, 2011). For instance, Kostopoulou and Jones (2005) studied possible changes in temperatureand precipitation-related climate extremes over the eastern Mediterranean region for the period 1958-2000.…”

Abstract. Recent and future changes in temperature and precipitation climate extremes are estimated using the Hadley Centre PRECIS ("Providing REgional Climates for Impacts Studies") climate model for the eastern Mediterranean and Middle East region. The area of interest is considered vulnerable to extreme climate events as there is evidence for a temperature rise while precipitation tends to decline, suggesting likely effects on vital socioeconomic sectors in the region. Observations have been obtained for the recent period ) and used to evaluate the model output. The spatial distribution of recent temporal trends in temperature indicates strong increasing in minimum temperature over the eastern Balkan Peninsula, Turkey and the Arabian Peninsula. The rate of warming reaches 0.4-0.5 • C decade −1 in a large part of the domain, while warming is expected to be strongest in summer (0.6-0.7 • C decade −1 ) in the eastern Balkans and western Turkey. The trends in annual and summer maximum temperature are estimated at approximately 0.5 and 0.6 • C decade −1 respectively. Recent estimates do not indicate statistically significant trends in precipitation except for individual sub-regions. Results indicate a future warming trend for the study area over the last 30 years of the 21st century. Trends are estimated to be positive and statistically significant in nearly the entire region. The annual trend patterns for both minimum and maximum temperature show warming rates of approximately 0.4-0.6 • C decade −1 , with pronounced warming over the Middle Eastern countries. Summer temperatures reveal a gradual warming (0.5-0.9 • C decade −1 ) over much of the region. The model projects drying trends by 5-30 % in annual precipitation towards the end of the 21st century, with the number of wet days decreasing at the rate of 10-30 days year −1 , while heavy precipitation is likely to decrease in the high-elevation areas by 15 days year −1 .

As a result of rapid urbanization worldwide, the vegetation areas, grasslands, and forests were replaced with construction and buildings. It is known that roads, pavements, concrete surfaces and walls all absorb sunlight during daytime and reflect heat as heat waves at night. It is clear that green areas have a significant role in urban life. Most of the research conducted in this field has shown that green areas mitigate the urban heat island, improve air quality, decrease noise and manage stormwater within the cities. Green spaces, green roofs, green walls, street trees, and water sources all have a positive impact on urban temperatures. Unfortunately, due to the rapid expansion in urbanization activities in Kyrenia, northern Cyprus, urban green spaces are decreasing at an alarming rate. Therefore, two different experimental works have been applied within the region; the first of these studies has been conducted on Ziya Rızkı Avenue. In this first study, temperature differences of shading with and without trees were measured. Additionally, the second study focused on the temperature differences between urban and rural areas. In the second research, urban and rural spaces were measured concurrently over a period of one month. It was proved by both studies that green spaces mitigate urban temperatures. Therefore, research results should be taken into consideration and architects, urban designers and planners should pay attention to green areas, street trees, parks, green roofs, and vertical green system establishments.
