Abstract Darma Dam is located in the upstream of Cisanggarung River, Kuningan Regency, West Java Province. Darma Dam construction dated from about 1922. Indonesian government continued the construction and began operating in 1962. With effective storage of about 40 million m3, Darma Dam provides water for about 22 thousand irrigation areas and bulk water for several cities and regencies. Several problems encountered in Darma Dam operation and water management are 1) increasing water demand from domestic and industrial sectors, and 2) high inflow variation during the dry and wet season, resulting in a large amount of water spill from the dam spillway. This paper addressed the impact of climate change on the inflow variation of Darma Dam in the dry and wet seasons. Further analysis shows average water spills from the spillway during the wet season may increase from about 12 million m3/year in the present condition to about 20 million m3/year in 2020-2050, while the average water volume during the dry season may reduce from 22.5 million m3 in the present condition to about 20.7 million m3 in 2020-2050. This study suggests that dam operation need adjustment in the future as part of adaptation to climate change.

Impacts Of Climate Change

The effects of climate change projected for 2050 to 2079 relative to the 1968–2014 reference period were evaluated using 39 CMIP5 models under the RCP8.5 emissions scenario in the Guayas River basin. The monthly normalized precipitation index (SPI) was used in this study to assess the impact of climate change for wet events and droughts from a meteorological perspective. The GR2M model was used to project changes in the streamflow of the Daule River. The climate projection was based on the four rigorously selected models to represent the climate of the study area. On average, an increase in temperature (~2 °C) and precipitation (~6%) is expected. A 7% increase in precipitation would result in a 10% increase in streamflow for flood periods, while an 8% decrease in precipitation could result in approximately a 60% reduction in flow for dry periods. The analysis of droughts shows that they will be more frequent and prolonged in the highlands (Andes) and the middle part of the basin. In the future, wet periods will be less frequent but of greater duration and intensity on the Ecuadorian coast. These results point to future problems such as water deficit in the dry season but also increased streamflow for floods during the wet season. This information should be taken into account in designing strategies for adaptation to climate change.

The Impact

This study aims to determine the impact of climate change on market garden production in the extreme south of Mali through the perception and adaptation of market gardeners to climatic phenomena. The study used two models, namely the probit selection and Heckman results models and multinomial logistic regression, based on data collected from producers. A total of 194 producers were surveyed. The results of Heckman's probit model indicate that experience in agriculture and the educational level of the producers are the two main determinants of producers' perception and simultaneous adaptation to climate change. Among these variables agricultural experience is both positively and negatively correlated with perception.

<p>Nature-Based Solutions (NBS) appear as some relevant alternatives to mitigate the consequences of climate change. For this reason, they are promoted for the implementation of the national plan for adaptation to climate change (PNACC) in France, in line with the Paris Agreement, the strategy of the European Union for adaptation to climate change and the French national strategy for biodiversity.</p><p>Nevertheless, this ambitious goal of democratizing NBS poses some institutional and technical challenges because many obstacles remain to their implementation. Overcoming these shortcomings is the objective of the LIFE integrated project called ARTISAN (Achieving Resiliency by Triggering Implementation of nature-based Solutions for climate Adaptation at a National scale). Coordinated by the French Biodiversity Office (OFB), its consortium regroups several local authorities, technical, research and education institutes.</p><p>For this purpose, ARTISAN is creating a framework promoting the implementation of NBS by improving scientific and technical knowledge about them, then by developing and disseminating relevant tools for project leaders (for the design, sizing, implementation and evaluation of ecosystem performance).</p><p>To demonstrate that NBS can respond to a diversity of climatic, ecological and institutional contexts, 10 pilot sites will be monitored in metropolitan and overseas France. The concerned issues are for example the reduction of urban heat island by the de-waterproofing of the public space, the limitation of the impact of cyclonic episodes on the urbanized coastline overseas by promoting the restoration of the mangrove, and the decrease of agricultural water stress during the low flow period by the hydromorphological restoration of wetlands. These pilot sites will serve to develop, improve and validate operational tools, methods and trainings devoted to practitioners.</p>

The Impact

AbstractMajor global crops in high-yielding, temperate cropping regions are facing increasing threats from the impact of climate change, particularly from drought and heat at critical developmental timepoints during the crop lifecycle. Research to address this concern is frequently focused on attempts to identify exotic genetic diversity showing pronounced stress tolerance or avoidance, to elucidate and introgress the responsible genetic factors or to discover underlying genes as a basis for targeted genetic modification. Although such approaches are occasionally successful in imparting a positive effect on performance in specific stress environments, for example through modulation of root depth, major-gene modifications of plant architecture or function tend to be highly context-dependent. In contrast, long-term genetic gain through conventional breeding has incrementally increased yields of modern crops through accumulation of beneficial, small-effect variants which also confer yield stability via stress adaptation. Here we reflect on retrospective breeding progress in major crops and the impact of long-term, conventional breeding on climate adaptation and yield stability under abiotic stress constraints. Looking forward, we outline how new approaches might complement conventional breeding to maintain and accelerate breeding progress, despite the challenges of climate change, as a prerequisite to sustainable future crop productivity.

Purpose This study aims to analyze the media coverage of the impact of extreme weather events (EWE) and related risk management activities in Brazil. Design/methodology/approach Using a documentary analysis, the authors examined the media coverage of droughts and floods from 2003 to 2013 with concomitant official reports. Findings The results indicate that although media coverage conveys the direct impact of floods and droughts on society, it underemphasizes the importance of risk management activities. Moreover, the private sector rarely engages in risk management and mitigation activities, despite the documented supply chain disruptions. Research limitations/implications This study focuses solely on media coverage as provided by wide-circulation newspaper in Brazil and would benefit by being extended to all media platforms. Practical implications The results highlight the need for private sector involvement in risk management activities to facilitate the adaptation to climate change. Social implications The study reveals the deficiency of existing reports and lack of awareness regarding EWE. Originality/value The study contributes by focusing on climate awareness and how society can adapt to climate change, as well as how businesses can improve supply chain operations to facilitate smoother risk management.

The Impact

In an earlier paper (Kirby et al. 2014a), we showed that climate change and a new policy which reallocates water to the environment will impact both the flow of water and the income derived from irrigation in the Murray–Darling Basin. Here, we extend the analysis to consider irrigator and environmental water management strategies to adapt to these new circumstances. Using an integrated hydrology-economics model, we examine a range of strategies and their impact on flows and the gross income of irrigation. We show that the adaptation strategies provide a range of flow and economic outcomes in the Basin. Several strategies offer significant scope to enhance flows without large adverse impacts on the gross income of irrigation overall. Some environmental water management strategies enhance flows in the Murray part of the basin even under the drying influence of a projected median climate change. Irrigator strategies that include carryover of water in storage from one year to the next provide for lesser year to year variability in gross income and may be regarded as more advantageous in providing security against droughts. Flows and the gross income of low value irrigation industries strategies are sensitive to climate change, irrespective of adaptation strategy. Should a projected dry extreme climate change be realized, no strategy can prevent a large reduction in flows and also in gross income, particularly of low value irrigation industries. Nevertheless, environmental water management strategies mitigate the impact on flows, and in some cases may also help mitigate the impacts on gross income. High value irrigation industries are less affected (in terms of gross income, though net income will reduce because of rising water prices) by projected climate change, consistent with observation in the recent long term drought.

Abstract Considering the ongoing violence taking place in the Middle East and North Africa (MENA) region, especially within Syria and Iraq, it is essential to provide an accurate explanation of causes in order to develop an adaptation model. In addition to discussing the climate-related concerns associated with the emergence of violence, this paper considers how tackling the environmental crisis in MENA will improve living standards and lead toward sustainable development. As a supplement to a range of secondary data, a small selection of individuals who have escaped the recent conflicts have been interviewed. Because this potential sample pool is small, and the ongoing violence precludes fieldwork in the MENA region, this study provides only a preliminary exploration of the topic. A more detailed study is desirable, if and when it is feasible to conduct such research. As a potential adaptation to climate change in the region, permaculture is presented through illustrations of its capabilities for redressing some of the underlying causes of violence in the MENA region.

The Impact

Bhumibol Dam is the largest dam in the central region of Thailand and it serves as an important water resource. The dam’s operation relies on reservoir operating rules that were developed on the basis of the relationships among rainfall-inflow, water balance, and downstream water demand. However, due to climate change, changing rainfall variability is expected to render the reliability of the rule curves insecure. Therefore, this study investigated the impact of climate change on the reliability of the current reservoir operation rules of Bhumibol Dam. The future scenarios from 2000 to 2099 are based on EC-EARTH under RCP4.5 and RCP8.5 scenarios downscaled by RegCM4. MIKE11 HD was developed for the inflow simulation. The model generates the inflow well (R2=0.70). Generally, the trend of increasing inflow amounts is expected to continue in the dry seasons from 2000-2099, while large fluctuations of inflow are expected to be found in the wet seasons, reflecting high uncertainties. In the case of standard deviations, a larger deviation is predicted under the RCP8.5 scenario. For the reservoir’s operation in a climate change study, standard operating procedures were applied using historical release records to estimate daily reservoir release needed to serve downstream water demand in the future. It can be concluded that there is high risk of current reservoir operating rules towards the operation reliability under RCP4.5 (80% reliability), but the risk is lower under RCP8.5 (87% reliability) due to increased inflow amounts. The unmanageability occurs in the wet season, cautioning the need to redesign the rules.

Buildings play a vital economic and social role in society and are vulnerable to climate change. This paper suggests a strategic approach for existing buildings to withstand climate change. It emphasises the most likely climate impacts, including the change in mean year values as well as the extent of maximum and minimum extremes, which are pointed out and set against a background of national and international agreements. Assumptions that form the basis for the scenarios are outlined and evaluated in a Danish context and similar evaluations can be drawn for other countries. As climate change progresses, the uncertainty of the scenarios leaves major challenges that will grow far more serious, if not addressed and taken into account in building design and into a strategy for the adaptation of existing buildings. An outline of the actions needed for developing a broad strategic approach to the adaptation to climate change for buildings is given. The actions include four stages: a survey of the performance, the impact of climate change, the vulnerability of the existing building stock and climate adaptation needs. This leads to the identification of a risk-based strategic framework for adaptation to climate change based on the results of a vulnerability analysis. In addition, this paper describes some issues that must be addressed in case a strategic approach is not developed, as the building sector is continuously investing in measures to adapt to climate change.
