  • Critical review of salinity intrusion in rivers and estuaries
    • Authors: Ruqayah Mohammed; Miklas Scholz
      Pages: 1 - 16
      Abstract: There is scientific evidence of accelerated sea level rise and saline intrusion. Some impacts, such as stratification and estuarine circulation, are subtle; others are dramatic including shifts in salt-sensitive habitats and limited water availability of suitable quality for industrial and municipal uses. These results have become a remarkable reality resulting in a set of integrated surface water organisation issues. Tremendous population increases overwhelming many coastal areas have expanded the problem. These challenges have been studied from many perspectives using various objectives and methodologies, and then arriving at different findings. However, all research assured that significant rises in sea level have influenced estuaries and tidally affected rivers, and these observations are expected to become rapidly worse in the future. This study introduces, categorises, critically investigates, and synthesises the most related studies regarding accelerated sea level rise and challenges of the development associated with the resources of surface water in estuaries and tidally-affected rivers. This critical review reveals that there is a need for research that focuses on the development of sustainable surface water resources.

  • Adaptation and mitigation of climate change in vegetable cultivation: a
    • Authors: A. V. V. Koundinya; P. Pradeep Kumar, R. K. Ashadevi, Vivek Hegde, P. Arun Kumar
      Pages: 17 - 36
      Abstract: Climate change is an unavoidable phenomenon of natural and anthropogenic origin against which mitigation and adaptation are required to reduce the magnitude of impact and vulnerability, to avoid risk in vegetable farming and to ensure sustainable livelihoods of the agricultural community. Genetic improvement of vegetable crops is an appropriate adaptation strategy to cope with climate change adversities. A combination study of genomics and phenomics provides a clear understanding of the environment's effect on the transformation of a genotype into phenotype. Grafting of a susceptible scion cultivar onto a resistant rootstock is another way of utilising plant biodiversity against climate change. Agronomic practices such as resource conservation technologies, mulching, organic farming, carbon sequestration by cropping systems and agroforestry provide a suite of possible strategies for addressing the impacts of climate change on vegetable production. Protected cultivation and post-harvest technology can be significant practices in facing the challenges of climate change. Weather forecasting models and growth simulation models can be used to predict the possible impact of climate change on vegetable crop production and they also help in framing necessary adaptation measures.

  • Decrease of the water recharge and identification of water recharge zones
           in the Alto Atoyac sub-basin, Oaxaca, as a result of climate change
    • Authors: Edwin Antonio Oȷeda Olivares; Salvador Isidro Belmonte Jimenez, Tim K. Takaro, Jose Oscar Campos Enriquez, Maria Ladron de Guevara Torres
      Pages: 37 - 57
      Abstract: This study analyzes effects of climate change (CCh) and of the increase of impervious surfaces on the groundwater recharge in the Alto Atoyac sub-basin (Oaxaca, southern Mexico). Water recharge was modeled based on HELP 3.95D; temperature and precipitation were derived, for a near (2015–2039) and a far distant future scenario, from GFDL-CM3 global circulation model (GCM), which describes the climate of Mexico under the RCP8.5 scenario. Potential recharge loss zones for the period of 1979–2013 were estimated through a remote sensing analysis. The actual estimated mean annual recharge of 169 million cubic metres could be reduced by 17.97% and 65.09% according to the analyzed CCh scenarios, and the loss of 135 km2 of permeable soil would represent additionally 2.65 × 106 m3 of non-infiltrated water. This study indicates three sites, with high recharge potential, and it can be used to propose local adaptations to guarantee the availability of the water resource in the studied sub-basin.

  • Comparison of annual maximum rainfall events of modern rain gauge data
           (1961-2010) and Chukwooki data (1777-1910) in Seoul, Korea
    • Authors: Chulsang Yoo; Minkyu Park, Hyeon Jun Kim, Changhyun Jun
      Pages: 58 - 73
      Abstract: In this study, the annual maximum rainfall event series were constructed and compared for both the modern flip-bucket type rainfall data, collected since 1961 (the modern data), and the old Chukwooki rainfall data, collected from 1777 to 1910 (the Chukwooki data). First, independent rainfall events were derived, by applying the same rainfall threshold of 2 mm and data collection time interval of 2 hours, to both the Chukwooki and the modern data. Annual maximum rainfall event series were then constructed, by applying Freund's bivariate exponential distribution annually. Finally, bivariate frequency analysis was done for the annual maximum rainfall event series constructed, by applying the bivariate logistic model to evaluate and quantify their characteristics. The results are in summary: (1) characteristics of the Chukwooki rainfall events and modern rainfall events are very similar to each other; (2) the annual maximum rainfall events of modern data are slightly larger than those of the Chukwooki data. The total rainfall depth per rainfall event for any given return period is thus estimated to be a little higher for the modern data than that of the Chukwooki data. However, based on the findings in this study, it could not be concluded that the rainfall characteristics have significantly changed during the last 200 years.

  • Impacts of regional climate and teleconnection on hydrological change in
           the Bosten Lake Basin, arid region of northwestern China
    • Authors: Huaijun Wang; Yingping Pan, Yaning Chen
      Pages: 74 - 88
      Abstract: This investigation examined effects of climate change, measured as annual, seasonal, and monthly air temperature and precipitation from 1958 to 2010, on water resources (i.e., runoff) in the Bosten Lake Basin. Additionally, teleconnections of hydrological changes to large-scale circulation indices including El Nino Southern Oscillation (ENSO), Arctic Oscillation (AO), North Atlantic Oscillation (NAO), Tibetan High (XZH), westerly circulation index (WI), and northern hemisphere polar vortex area index (VPA) were analyzed in our study. The results showed the following. (1) Annual and seasonal air temperature increased significantly in the Bosten Lake Basin. Precipitation exhibited an increasing trend, while the significance was less than that of temperature. Abrupt changes were observed in 1996 in mountain temperature and in 1985 in plain temperature. (2) Runoff varied in three stages, decreasing before 1986, increasing from 1987 to 2003, and decreasing after 2003. (3) Precipitation and air temperature have significant impacts on runoff. The hydrological processes in the Bosten Lake Basin were (statistically) significantly affected by the northern hemisphere polar vortex area index (VPA) and the Tibetan High (XZH). The results of this study are good indicators of local climate change, which can enhance human mitigation of climate warming in the Bosten Lake Basin.

  • Summertime runoff variations and their connections with Asian summer
           monsoons in the Yangtze River basin
    • Authors: Jian Tang; Qingyun Li, Jin Chen
      Pages: 89 - 100
      Abstract: Research on the summertime runoff variations and their connections with Asian summer monsoons can give insights for explanation of the hydrological processes and climate change in the Yangtze River basin. Currently, regional studies are focused on the relationships between Asian summer monsoons and meteorological elements. However, research on the runoff variations and their connections to Asian summer monsoons is still scarce. With the help of continuous wavelet transform, cross-wavelet, and wavelet coherence analysis methods, this research explored multiscale summertime runoff variations and their connections with Asian summer monsoons during 1957–2012 in the Yangtze River basin. The results indicate that periodical characteristics of summertime runoff along the mainstream of the Yangtze River basin have distinct differences. Upstream flow is characterized by interannual (1- to 3-year), and downstream by decadal (7- to 10-year) oscillations over certain time periods. In the source region, summertime runoff is primarily influenced by the South Asian summer monsoons (SASM), and mainly in-phase relationships are detected between the summertime runoff and SASM indices. In the midstream and downstream regions, summertime runoff is primarily influenced by the East Asian summer monsoons (EASM), and mainly anti-phase relationships are detected between the summertime runoff and EASM indices.

  • Comparison of evaporation rate on open water bodies: energy balance
           estimate versus measured pan
    • Authors: Yohannes Yihdego; John A. Webb
      Pages: 101 - 111
      Abstract: Much attention has been paid to establish accurately open water evaporation since the lake itself is the largest consumer of water. The aim of this study is to assess the discrepancy in the measured (pan evaporation) and estimated (Penman) evaporation rate, seasonally, based on the results from a 37-year energy budget analysis of Lake Burrumbeet, Australia. The detailed analysis of meteorological data showed that evaporation is fully radiation driven and that the effect of wind is minimal. Sensitivity analysis shows that evaporation estimation is more sensitive to shortwave radiation followed by relative humidity. An increase or decrease of estimated shortwave radiation by 10% could result in an increase or decrease of estimated evaporation up to 18%. The Penman combination method is relatively the least sensitive to wind speed but could bring a significant effect on the lake level fluctuation since a 10% increase of wind speed increases the estimated evaporation by 2.3%. The current analysis highlights the relative roles of radiation, temperature, humidity, and wind speed in modulating the rate of evaporation from the lake surface, by employing an inter-monthly seasonal adjustment factor to the estimated evaporation in the lake water budget analysis, with implications for the inter-monthly variability and short-term trends assessment of water resource through various meteorological parameters.

  • Measuring climate change adaptation in Pacific small island states:
           nissology and success
    • Authors: Michael B. Schwebel
      Pages: 112 - 123
      Abstract: Pacific small island states (PSIS) currently experience harsh impacts of a changing climate: sea level rise, saltwater intrusion, internal migration and displacement. Are adaptation strategies based upon island-centric principles more successful than those originating from a more continental point of view' This research examined the principles of island-centric thinking using an island-centric lens by which to determine ‘successful’ climate adaptation planning. The findings illustrate a statistically significant relationship between PSIS that have higher nissological (island-centric) levels displayed within their climate change action plans (CCAPs) and CCAPs that were found to be more successful. In other words, highly nissological states are forecasted to be more successful in planning for the current and future impacts of climate change than those with lower nissological scores. In total, nissology explains approximately 28.37% of a PSIS's success. The policy relevance is rooted in the unique cultural, geographical, and social aspects of islands. Findings are applicable to other islands as well countries that share islander-based qualities. The methodological and quantitative-based areas of the study assist in forming policy-relevant determinations for island societies based on the climate-related parameters and metrics tested and evaluated herein.

  • Observed and simulated climate and climate change in the lower Neretva
           river basin
    • Authors: Marȷana Gaȷić–Čapka; Ivan Guttler, Kseniȷa Cindrić, Čedo Branković
      Pages: 124 - 136
      Abstract: The lower Neretva river basin includes a fertile valley at the estuary into the Adriatic Sea, where intense agricultural production occurs, and the higher terrain where drinking water resources exist. To provide input for the further assessment of crop-yield production and hydrological risks, climate and climate change were analysed using the Opuzen station air temperature and total precipitation data for the 1961–2015 period. Both historical and future climates (2021–2050) were assessed based on simulations of three regional climate models (RCMs). The RCMs were forced by the observed concentrations of greenhouse gases (GHGs) from 1951 to 2000, and the IPCC A1B scenario of the GHG emissions was applied from 2001 onwards. The models were compared with the observations, and two bias adjustment methods were evaluated. The results generally showed a significant increase in the mean annual and seasonal temperature and a weak decreasing trend in annual and seasonal precipitation. Projections revealed a predominant increase in the mean temperature by the mid-21st century for all three RCMs (between 0.5 and 3.5 °C). The precipitation changed by between −60 and +60% throughout the year for the different models, although the changes generally were not statistically significant.

  • Evaluation of the impacts of future hydrological changes on the
           sustainable water resources management of the Richmond River catchment
    • Authors: Hashim Isam Jameel Al-Safi; P. Ranjan Sarukkalige
      Pages: 137 - 155
      Abstract: The conceptual rainfall–runoff (HBV model) is applied to evaluate impacts of future climate changes on the hydrological system of the Richmond River catchment, Australia. Daily observed rainfall, temperature and discharge and long-term monthly mean potential evapotranspiration from the hydro-meteorological stations within the catchment over the period 1972–2014 were used to run, calibrate and validate the HBV model before the simulation. Future climate signals were extracted from a multi-model ensemble of eight global climate models (GCMs) of the CMIP5 under three scenarios (RCP2.6, RCP4.5 and RCP8.5). The calibrated HBV model was forced with the downscaled rainfall and temperature to simulate future streamflow at catchment outlet for the near-future (2016–2035), mid (2046–2065) and late (2080–2099) 21st century. A baseline run, with baseline climate period 1971–2010, was used to represent current climate status. Almost all GCMs’ scenarios predict slight increase in annual mean rainfall during the beginning of the century and decrease towards the mid and late century. Modelling results also show positive trends in annual mean streamflow during the near-future (13–23%), and negative trends in the mid (2–6%) and late century (6–16%), under all scenarios compared to the baseline-run. Findings could assist in managing future water resources in the catchment.

  • Modeling impacts of climate change and human activities on groundwater
           resources using MODFLOW
    • Authors: Hossein Malekinezhad; Fatemeh Barzegai Banadkooki
      Pages: 156 - 177
      Abstract: This paper analyzes the impacts of climate change and human pressures on Yazd-Ardakan aquifer using the Hadley Centre Coupled Model, version 3 (HADCM3) circulation Model and A2 emission scenario. Water levels in the study aquifer were simulated using three-dimensional finite-difference groundwater model (MODFLOW 2000) with GMS 8.3 as pre- and postprocessing software. Input for groundwater recharge time series under the climate change scenarios were derived using a regression equation based on the cumulative deviation from mean rainfall using MATLAB. Human pressures on the aquifer were modeled through climate change impacts on water requirements of cultivated areas. Three scenarios were simulated to represent the effects of climate change and human pressures on aquifer storage and hydraulic head. Climate change and human pressures (scenario 1) will reduce aquifer storage and result in decreasing hydraulic head by −0.56 m year−1. Reduction in pumping water under scenario 2 (irrigation system modification) and scenario 3 (irrigation system modification and cropping patterns) will result in groundwater level fluctuation of about −0.32 and 0.08 m year−1, respectively. Scenario 3 is capable of restoring and protecting the groundwater resources in Yazd-Ardakan aquifer. The results of this study are useful to obtain sustainable groundwater management in Yazd-Ardakan aquifer.

  • Changes in climate zones across Turkey
    • Authors: Bulent Selek; I. Kaan Tuncok, Zeliha Selek
      Pages: 178 - 195
      Abstract: Turkey lies in a critical region that is projected to be one of the most vulnerable to the impacts of climate change in the Mediterranean region. In this study, climatic zones of Turkey were classified with respect to their climatic and meteorological characteristics. The Thornthwaite precipitation efficiency index was used to identify aridity and humidity characteristics. The index values were mapped to determine climate zones and associated climate classes and to evaluate change in time and space. Two distinct periods (1950–1980 and 1981–2010) were used to assess climatic conditions and evaluate historical changes. The Thornthwaite index indicated significant spatial variations of climate parameters across Turkey with varying degrees of vulnerability. The results indicate that during the 60-year time frame, no arid zones had been experienced in Turkey. On the other hand, an increase of semi-dry and dry humid zones and a decrease of semi-dry–less humid, semi-humid and humid zones had been experienced. In this context, it is important to note that semi-arid zones have increased substantially (approximately 14%) between the two 30-year periods.

  • Finding land cover change impacts on low flow regimes
    • Authors: Chandramouli V. Chandramouli; Sivakumar Buddaraju, Nicholas Kaoukis
      Pages: 196 - 206
      Abstract: Climate changes, as well as land cover changes, affect the flow regimes in streams. Understanding the contributions of climate variables and land cover changes on low flows will help planners and decision makers to improve water resources management. An approach which uses data driven artificial neural networks (ANNs) is proposed in this study. Land cover, rainfall, snow and temperature were used as inputs to the ANN model. In this approach, an index called relative strength effect was used to assess the contribution of each input used in ANN. The proposed approach was experimented in three contrasting watersheds in northwest Indiana, USA. The study indicates that the changes in low flow regime for a less urbanized watershed were explained by land cover changes up to 30% while the remaining 70% variations were explained by meteorological inputs. In the watershed with a more developed area, the low flow variations were influenced up to 80% by meteorological inputs.

  • Evaluation of the impacts of climate variability on rainfed maize
           production over the Wami-Ruvu basin of Tanzania
    • Authors: Philbert Luhunga
      Pages: 207 - 222
      Abstract: In this study, the impact of inter-seasonal climate variability on rainfed maize (Zea mays) production over the Wami-Ruvu basin of Tanzania is evaluated. Daily high-resolution climate simulations from the Coordinated Regional Climate Downscaling Experiment_Regional Climate Models (CORDEX_RCMs) are used to drive the Decision Support System for Agro-technological Transfer (DSSAT) to simulate maize yields. Climate simulations for the base period of 35 years (1971–2005) are used to drive DSSAT to simulate maize yields during the historical climate. On the other hand, climate projections for the period 2010–2039 (current), 2040–2069 (mid), and 2070–2099 centuries for two Representative Concentration Pathway (RCP45 and 85) emission scenarios are used to drive DSSAT to simulate maize yields in respective centuries. Statistical approaches based on Pearson correlation coefficient and the coefficients of determination are used in the analysis. Results show that rainfall, maximum temperature, and solar radiation are the most important climate variables that determine variation in rainfed maize yields over the Wami-Ruvu basin of Tanzania. They explain the variability in maize yields in historical climate condition (1971–2005), present century under RCP 4.5, and mid and end centuries under both RCP 4.5 and RCP 8.5.

  • Prospects of pond ecosystems as resource base towards community based
           adaptation (CBA) to climate change in coastal region of Bangladesh
    • Authors: Md. Golam Rabbani; Syed Hafizur Rahman, Sirazoom Munira
      Pages: 223 - 238
      Abstract: Climate-induced hazards are adversely affecting the pond ecosystems in Bangladesh. Most of the poor communities collect water from isolated ponds for drinking and other domestic needs. This paper explores how the small pond ecosystems and associated livelihoods of the coastal communities are vulnerable and argues that the pond ecosystem can be a potential resource base for community based adaptation in the coastal regions of Bangladesh. A set of quantitative and qualitative tools were applied to 309 households across five villages. The study showed that 96% of the respondents are dependent on pond water for drinking. More than 50% households expressed that temperature, rainfall variations and salinity intrusion, directly and indirectly, affect the pond water. Physical parameter values of temperature, pH and salinity from the ponds showed changes across different seasons. Drinking water scarcity during pre-monsoon (March–May), winter (Dec–Feb), disaster and immediate post-disaster period among the communities is high. Salinity intrusion and surface runoff caused by excessive rainfall in short periods also cause deterioration in the quality of pond water. However, successful examples of pond water usage emerged through the discussions, especially during a post-disaster crisis, which strengthens the idea that ponds could be a resource base for community-based adaptation in the coast of Bangladesh.
