Culture Strategies

In Bangladesh, aquaculture is critically important in terms of providing food and nutrition, sustainable livelihoods, income, and export earnings. Nevertheless, aquaculture in Bangladesh has faced recent concerns due to climate change. Aquaculture is vulnerable to a combination of climatic factors, such as global warming, rainfall variation, flood, drought, temperature fluctuation, and salinity change. Considering the vulnerability of fish production to the impacts of climate change, tilapia farming is one of the possible strategies for adaptation to climate change. The positive culture attributes of tilapia are their tolerance to low water levels and poor water quality with rainfall variation, temperature fluctuation, and salinity change. In fact, tilapia farming is possible in a wide range of water environments, including freshwater, brackish water, and saltwater conditions. We suggest that appropriate tilapia culture strategies with institutional support and collaboration with key stakeholders are needed for adaptation to environmental change.

Lake level is a sensitive integral indicator of climate change on regional scales, especially in enclosed endorheic basins. Eurasia contains the largest endorheic zone with several large terminal lakes, whose water levels recently underwent remarkable variations. To address the patterns of these variations and their links to the climate change, we investigated the variability of levels in 15 lakes of three neighboring endorheic regions—Central Asia, Tibetan Plateau, and Mongolian Plateau. Satellite altimetry revealed a heterogeneous pattern among the regions during 1992–2018: lake levels increased significantly in Central Asia and the Tibetan Plateau but decreased on the Mongolian Plateau. The shifts to the increasing trend were detected since 1997 in Central Asia, since 1998 in the southern part of the Tibetan Plateau, and since 2005 in its northern part. The shift in air temperatures around 1997 and the precipitation shifts around 1998 and 2004 contributed to the trend’s turning points, with precipitation being the major contributor to the heterogeneous pattern of lake levels. Our findings reveal the linkage of the heterogeneous pattern of lake levels to climatic factors in the endorheic basins, providing a further understanding of the hydrological regime in the Eurasian endorheic zone and its sensitivity to climate change.

AbstractClimate change will have a profound effect on vine growing worldwide. Wine quality will also be affected, which will raise economic issues. Possible adaptations may result from changes in plant material, viticultural techniques, and the wine-making process. Relocation of vineyards to cooler areas and increased irrigation are other options, but they may result in potential conflicts for land and water use. Grapes are currently grown in many regions around the world, and growers have adapted their practices to the wide range of climatic conditions that can be found among or inside these areas. This knowledge is precious for identifying potential adaptations to climate change. Because climate change affects all activities linked to wine production (grape growing, wine making, wine economics, and environmental issues), multidisciplinary research is needed to guide growers to continue to produce high-quality wines in an economical and environmentally sustainable way. An example of such an interdisciplinary study is the French LACCAVE (long-term adaptation to climate change in viticulture and enology) project, in which researchers from 23 institutes work together on all issues related to the impact of climate change on wine production.

Bioclimatic Envelope

Potential impacts of projected climate change on biodiversity are often assessed using single-species bioclimatic ‘envelope’models. Such models are a special case of species distribution models in which the current geographical distribution of species is related to climatic variables so to enable projections of distributions under future climate change scenarios. This work reviews a number of critical methodological issues that may lead to uncertainty in predictions from bioclimatic modelling. Particular attention is paid to recent developments of bioclimatic modelling that address some of these issues as well as to the topics where more progress needs to be made. Developing and applying bioclimatic models in a informative way requires good understanding of a wide range of methodologies, including the choice of modelling technique, model validation, collinearity, autocorrelation, biased sampling of explanatory variables, scaling and impacts of non-climatic factors. A key challenge for future research is integrating factors such as land cover, direct CO2 effects, biotic interactions and dispersal mechanisms into species-climate models. We conclude that, although bioclimatic envelope models have a number of important advantages, they need to be applied only when users of models have a thorough understanding of their limitations and uncertainties.

The Impact

The climate of Sri Lanka has been fluctuating at an alarming rate during the recent past. These changes are reported to have pronounced impacts on the livelihoods of the people in the country. Water is central to the sustainable functioning of ecosystems and wellbeing of mankind. It is evident that pronounced variations in the climate will negatively impact the availability and the quality of water resources. The ecosystem-based adaptation (EbA) approach has proved to be an effective strategy to address the impact of climate change on water resources in many parts of the world. The key aim of this paper is to elaborate the wide range of benefits received through implementation of EbAs in field level, watershed scale, and urban and coastal environments in the context of Sri Lanka. In addition, this paper discusses the benefits of utilizing EbA solutions over grey infrastructure-based solutions to address the issues related to water management. The wide range of benefits received through implementation of EbAs can be broadly classified into three categories: water supply regulation, water quality regulation, and moderation of extreme events. This paper recommends the utilization of EbAs over grey infrastructure-based solutions in adaptation to climate change in the water management sector for the developing region due its cost effectiveness, ecofriendliness, and multiple benefits received on long-term scales. The findings of this study will unequivocally contribute to filling existing knowledge and research gaps in the context of EbAs to future climate change in Sri Lanka. The suggestions and opinions of this study can be taken into account by decision makers and water resources planning agencies for future planning of actions related to climate change adaptation in Sri Lanka.

AbstractGiven that climate change is a complex, systemic risk, addressing it requires new knowledge. One way of generating such new knowledge is through co-production, or collaborative development by a range of stakeholders with diverse backgrounds embedded in trans-disciplinary processes. This chapter reflects on emerging experiences of co-producing decision-relevant climate information to enable climate-resilient planning and adaptation to climate change in Africa. It outlines principles that have emerged and evolved through experiential learning from a wide range of co-production processes in Africa. It also uses case study experience from various contexts to highlight some of the more contextual challenges to co-production such as trust, power and knowledge systems and institutional factors (mandates, roles and incentives) and illustrates ways that trans-disciplinary co-production has addressed these challenges to mainstream a response to the climate challenge.

Climate change is projected to lead to a major reorganization of our forests. For example, higher annual mean temperatures, longer growth seasons and drier summers are predicted for many parts of central and southern Europe, and in North America. In order to understand the genetic adaptation to climate change we need a better understanding of the genetic regulation of key traits involved in tolerance of water and temperature stress. Oaks (Quercus spp.) are excellent model species to study the adaptation of forest trees to changing environments. They show a wide geographic distribution in Europe and in North America as dominant tree species in many forests growing under a wide range of climatic and edaphic conditions. With the availability of a growing amount of functional and expressional candidate genes we are now able to test the functional importance of genes by associating nucleotide variation in these genes with phenotypic variation in adaptive traits in segregating or natural populations. Studies trying to associate genetic variation with phenotypic variation in adaptive traits can be performed in full-sib families derived from controlled crosses (Quantitative Trait Loci [QTL] mapping) or in natural populations (association mapping). For several important adaptive traits QTL were mapped, the underlying genes have to be tested in natural populations. A future objective is to test whether genes that underlie phenotypic variation in adaptive traits are involved in local genetic adaptation and viability selection at the seedling stage, linked to reciprocal transplant experiments in order to assess the performance over climatic gradients.

Purpose – The purpose of this paper is to analyze the effects on urban flood from rapidly growing land and housing development projects in flood zones and water bodies in and around Dhaka. The paper further extends the analysis to generate an insight into Dhaka’s urban flood due to possible climate change effects on top of land and housing development projects effects. Design/methodology/approach – A mixed method was applied for this research comprising qualitative techniques for analyzing the date gathered from reviewing the policies including the Dhaka Metropolitan Development Plan reports, interviews, discussions and maps, whereas quantitative analysis was used to interpret the data gathered from the global positioning system (GPS) survey and questionnaire survey among the resident of the selected housing projects. Findings – Findings show that a large number of the projects have encroached flood-flow zones and ditches and drainage channels through massive land filling, which resulted in quick changes of land use with wide range of impacts on environment and habitat quality. This study highlighted that the potential climate change impact involves increasing rainfall and subsequent increase flooding. Besides, vast area will be submerged under water and increased warming in the city from high speed built-up area by unauthorized land development. Originality/value – The results of the research can be taken into consideration when making political decisions concerning adaptation to climate change.

Impacts Of Climate Change

AbstractEstimating the potential impacts of climate change requires understanding the ability of agents to adapt to changes in their climate. This paper uses panel data from India spanning from 1956 to 1999 to investigate the ability of farmers to adapt. To identify adaptation, the author exploits persistent, multidecadal monsoon regimes during which droughts or floods are more common. These regimes generate medium-run variation in average rainfall, and there is spatial variation in the timing of the regimes. Using a fixed-effects strategy, she tests whether farmers have adapted to the medium-run rainfall variation induced by the monsoon regimes. The author finds evidence that farmers adjust their irrigation investments and their crop portfolios in response to the medium-run rainfall variation. However, adaptation only recovers a small fraction of the profits farmers have lost due to adverse climate variation.

Abstract Background: Climate change is one of the major environmental challenge particularly affecting crop producers who depend on climate sensitive rainfed system. The contextual nature of farmers’ adaptation and coping strategies to climate change continues to arouse the interest of several researchers. This study contributed to this growing area of research by examining factors and processes explaining the choice of crop producers’ adaptation to dynamic climate change risks. Method and material: Data were collected through household survey and interview. Multistage sampling was employed for selecting 340 household heads for interview. Descriptive statistics and multinomial logistic models were employed to analysis data collected. Result and discussion: Results indicate that despite perceived increase in current and future climate change risks, farmers are testing and implementing a range of strategies by adjusting sowing date, using late or early maturing varieties, diversifying crop production using legumes and migrating to nearby cities in search of additional jobs as an income source during dry seasons. Contexts-specific factors significantly influencing the choice of adaptation strategies include gender of the household, access to extension services, level of awareness and perceptions, timely access to climate and weather information and size of landholding per household. Conclusion: Based on the results of the study, it was concluded that the choice of adaptation to climate change is driven by much detailed socio-economic and institutional factors in addition to dynamic climatic factors. The study recommended that continuous financial, policy and technical support in terms of research, extension, innovation and awareness creation on improving behavioural and socio-economic aspects that influence adaptation choice should be provided.
