TL;DR: In this paper, the authors examined the nature and sustainability of locally adopted coping and adaptation strategies and examined their prospects for maladaptation in the face of climate change and found that local actors respond to perennial flooding with very diverse strategies with varying degrees of success and sustainability.
Abstract: Purpose – The number of poor and informal urban settlers in the world is rapidly growing, and they are increasingly vulnerable to the impacts of a changing climate. Therefore, understanding the nature and sustainability of locally adopted coping and adaptation strategies are key, yet still under-researched areas. Design/methodology/approach – Based on ethnographic research conducted in two poor, flood-prone municipalities in Pikine/Dakar, this paper identifies such coping and adaptation strategies and examines their prospects for maladaptation. Findings – The paper shows that poor urban dwellers are not mere passive spectators of climate change. With the very limited resources they have at their disposal, it is found that local actors respond to perennial flooding with very diverse strategies, which have varying degrees of success and sustainability. A key finding is that local coping and adaptation strategies are mainly maladaptive because they divert risks and impacts in time and space and have detrimen...

TL;DR: In this article, the authors examined the biophysical and socioeconomic impacts of climate change on maize production and food security in sub-Saharan Africa using adapted improved maize varieties and well-calibrated and validated bioeconomic models.
Abstract: Purpose – The purpose of this study is to examine the biophysical and socioeconomic impacts of climate change on maize production and food security in sub-Saharan Africa (SSA) using adapted improved maize varieties and well-calibrated and validated bioeconomic models. Design/methodology/approach – Using the past climate (1950-2000) as a baseline, the study estimated the biophysical impacts of climate change in 2050 (2040-2069) and 2080 (2070-2099) under the A1B emission scenario and three nitrogen levels, and the socioeconomic impacts in 2050. Findings – Climate change will affect maize yields across SSA in 2050 and 2080, and the extent of the impact at a given period will vary considerably between input levels, regions and maize mega environments (MMEs). Greater relative yield reductions may occur under medium and high-input intensification than under low intensification, in Western and Southern Africa than in Eastern and Central Africa and in lowland and dry mid-altitude than in highland and wet mid-alt...

TL;DR: In this paper, the authors present a critical review of some literature on climate change and migration through conceptualizing and contextualizing the linkages between the two topics and identify major qualitative and quantitative gaps.
Abstract: Purpose – This paper aims to present a critical review of some literature on climate change and migration through conceptualizing and contextualizing the linkages between the two topics. Much literature on links between climate change and migration tends to downplay ambiguities in the terms and the limited empirical evidence. Conceptualizing refers to the knowledge gaps and the need to understand and detail (even if not agreeing on) conceptual issues such as terminology, definitions, linkages, drivers, thresholds, implications, data requirements and methodologies. Contextualizing refers to understanding the climate change and migration debate within wider topical and geographical contexts. Results identify major qualitative and quantitative gaps. Qualitatively, limited material exists on why people react differently to similar environmental stressors and why certain outcomes may arise. Quantitatively, credible and verifiable measures are not always available for assessing the climate change impacts on mig...

TL;DR: Wang et al. as mentioned in this paper examined whether Chinese firms’ signals of green governance, including environmental management, green innovation, and greenhouse gas (GHG) and pollution emission, vary significantly with their ownership structure and aim of being environmentally sensitive.
Abstract: Purpose – This paper aims to examines whether Chinese firms’ signals of green governance, including environmental management, green innovation, and greenhouse gas (GHG) and pollution emission, vary significantly with their ownership structure and aim of being environmentally sensitive. Design/methodology/approach – From corporate social responsibility (CSR)-China website and CNINFO, a total of 781 CSR reports released during 2008-2010 were collected. The collected data were coded and analyzed using content analysis. Findings – In overall disclosure of environmental protection information (TotalEP), no significant difference existed between state-owned enterprises (SOEs) and privately owned enterprises (POEs). Chinese environmentally sensitive industries (ESIs) have a tendency to disclose significantly more information about their actions of environmental protection than their counterparts. Moreover, SOEs and ESIs scored higher than their counterparts on energy saving and carbon reduction and development o...

TL;DR: In this article, the authors investigated the awareness of coastal community towards climate change in Malaysia and explored the factors associated with their awareness toward the climate change, and found that fishermen are less aware toward climate change compared to other groups, such as housewives/retirees and students.
Abstract: Purpose – The present paper attempts to investigate the awareness of coastal community towards climate change in Malaysia and to explore the factors associated with their awareness toward the climate change. Design/methodology/approach – This is a quantitative study where a set of questionnaires was developed based on reviews of literature and series of instrument development meeting. Through a multi-stage cluster sampling, a total of 210 respondents from three coastal villages in Peninsular Malaysia were selected. Findings – The coastal community are shown to record a high mean score on their awareness toward changes relating to the sea, temperatures and the coast. Surprisingly, fishermen are found to be less aware toward climate change compared to other groups, such as housewives/retirees and students. Further analysis confirms that there are significant differences regarding coastal community awareness to changes relating to the sea, temperatures and the coast. Research limitations/implications – This ...

TL;DR: In this article, the authors investigated the long-term equilibrium relationship between carbon dioxide (CO2) emissions and total biomass consumption (BC) in Turkey, which has a rich diversity of ecological conditions prevailing throughout its regions.
Abstract: Purpose – The purpose of this study is to investigate the long-term equilibrium relationship between carbon dioxide (CO2) emissions and total biomass consumption (BC) in Turkey, which has a rich diversity of ecological conditions prevailing throughout its regions. Design/methodology/approach – Bounds tests and conditional error correction models under the autoregressive distributed lag approach have been applied to annual data that cover the 1980-2010 period. Findings – Results suggest that CO2 emissions are in a long-term equilibrium relationship with total BC in Turkey. BC has a negative effect on CO2 emissions; 1 per cent increase in total BC would lead to 0.029 per cent reduction in CO2 emissions. Long-term coefficient of fossil fuel consumption for CO2 emissions is positive and elastic, 1.247. Finally, conditional error correction model of the present study reveals that CO2 emission in Turkey converges to its economic long-term equilibrium very quickly by 93.7 per cent speed of adjustment through the...

TL;DR: The authors examined the perceptions and experiences of climate change by local farmers in the Northern Savannah zone of Ghana, using a questionnaire survey on a sample of 530 farmers, in-depth interviews and focus group discussions.
Abstract: Purpose – This paper aims to examine the perceptions and experiences of climate change by local farmers in the Northern Savannah zone of Ghana. Although recent scholarship shows that local people’s perceptions of climate change is necessary for devising strategies to deal with the problem, only a few researchers have examined local knowledge of climate change in Africa. Design/methodology/approach – Primary data were collected from six rural communities in the Northern Savannah zone of Ghana, using a questionnaire survey on a sample of 530 farmers, in-depth interviews and focus group discussions. Multinomial logistic regression was used to analyse variations in experience and perception of climate change. Findings – A majority of the farmers have noticed rising temperatures and declining rainfall. Their observations largely correspond with the evidence of changes recorded by weather monitoring stations. The perception of climate change is associated with locality of residence, gender and ownership of radi...

TL;DR: In this paper, the authors analyse how fish farmers manage climate-related risks and explore possible ways to strengthen risk management under current and future climate, and find that many risks are season, river and place specific; implying that the risk profiles of individual farms can vary substantially.
Abstract: Purpose – The purpose of this paper is to analyse how fish farmers manage climate-related risks and explore possible ways to strengthen risk management under current and future climate. Design/methodology/approach – In total, 662 fish farmers in sites across Northern Thailand were interviewed about risks to the profitability of their fish farms and ways such risks were managed. Nonlinear canonical correlation analysis was used to relate risk factors to management practices at farm and river levels. In total, 68 in-depth interviews with farmers and other stakeholders provided additional information on climate risk management practices. Findings – Farmers use a combination of adjustments to rearing practices, cropping calendars and financial and social measures to manage those risks, which they perceive as being manageable. Many risks are season, river and place specific; implying that the risk profiles of individual farms can vary substantially. Individual risks are often addressed through multiple practic...

TL;DR: In this article, the authors propose a collaborative approach toward an integrated vulnerability assessment to climate change in Germany that attempts to bridge the gap between scientific output and policy demand, which is similar to the definition of vulnerability as used by the Intergovernmental Panel on Climate Change.
Abstract: Purpose – This paper aims to propose a collaborative approach toward an integrated vulnerability assessment to climate change in Germany that attempts to bridge the gap between scientific output and policy demand. Design/methodology/approach – Conceptually, the approach follows the definition of vulnerability as used by the Intergovernmental Panel on Climate Change, but it has modified this basic concept. It clearly distinguishes between three time slices (presence, near and remote future) not only regarding the change in the climatic conditions but also socio-economic development trends. Findings – The paper concentrates on the selected methodological framework, the collaborative research design and those preliminary results of the nationwide vulnerability assessment that are transferable to other settings. Practical implications – A Vulnerability Network (“Netzwerk Vulnerabilitaet”) emerged from an applied research project commissioned under the Adaptation Action Plan of the German Strategy for Adaptati...

TL;DR: In this paper, the implication of trade on carbon emissions in a panel of eight highly trading Southeast and East Asian countries, namely, China, Indonesia, South Korea, Malaysia, Hong Kong, The Philippines, Singapore and Thailand, is analyzed.
Abstract: Purpose – The purpose of this paper is to analyse the implication of trade on carbon emissions in a panel of eight highly trading Southeast and East Asian countries, namely, China, Indonesia, South Korea, Malaysia, Hong Kong, The Philippines, Singapore and Thailand. Design/methodology/approach – The analysis relies on the standard quadratic environmental Kuznets curve (EKC) extended to include energy consumption and international trade. A battery of panel unit root and co-integration tests is applied to establish the variables’ stochastic properties and their long-run relations. Then, the specified EKC is estimated using the panel dynamic ordinary least square (OLS) estimation technique. Findings – The panel co-integration statistics verifies the validity of the extended EKC for the countries under study. Estimation of the long-run EKC via the dynamic OLS estimation method reveals the environmentally degrading effects of trade in these countries, especially in ASEAN and plus South Korea and Hong Kong. Pra...

TL;DR: In this paper, the authors put forward a methodological framework to provide a comparative assessment of available mitigation and adaptation strategies against climate change, focusing on specific parameters, leading to the most efficient package of alternatives for the area of Greece.
Abstract: Purpose – The purpose of this study is to put forward a methodological framework to provide a comparative assessment of available mitigation and adaptation strategies against climate change. Mitigation options aim at minimizing CO2 and other greenhouse gas emissions, in an effort to reduce the rate of increase in global temperature. On the other hand, adaptation options relate to the ability of the natural or human systems to handle the impact of the climate change and to adjust to its effects, seeking to eliminate the adverse consequences and take advantage of any beneficial outcomes. Design/methodology/approach – The methodology focuses on specific parameters, leading to the most efficient package of alternatives for the area of Greece. The selection of the “optimal” ranking of alternatives in a defined strategy is a sophisticated procedure, and a multi-criteria decision-making process was established. A questionnaire was designed and used as input to the overall framework, based on specific decision cr...
TL;DR: In this article, the authors provide a methodology for constructing farm household-level adaptation metrics for agriculture and water sectors, and investigate different issues associated with micro-level adaption strategies related to agriculture and the water sectors.
Abstract: Purpose – This study aims to provide a methodology for constructing farm household-level adaptation metrics for agriculture and water sectors. The livelihood of farm households is at risk now and in the foreseeable future, as both agriculture and water sectors are vulnerable to climate variability, particularly in developing nations. Adaptation is critical to protect their livelihood. Vulnerable farmers have adopted various adaptation mechanisms to counteract negative impacts of climate variability, though the extent varies temporally and spatially. Design/methodology/approach – It is, therefore, imperative to understand current adaptation practices for successfully implementing them. A few studies have emerged so far in this context, investigating different issues associated with micro-level adaptation strategies related to agriculture and water sectors, e.g. output and cost-effectiveness, and constraints related to farm, household and institutional levels. Findings – While such analysis is critical to e...
TL;DR: In this article, a joint assessment of issues related to the agricultural systems, i.e., agriculture, aquaculture and climate change response strategies, in the coastal districts with a panel of stakeholders is presented.
Abstract: Purpose – This paper aims to facilitate the joint assessment of issues related to the agricultural systems, i.e. agriculture, aquaculture and climate change (CC) response strategies, in the coastal districts with a panel of stakeholders; and to evaluate the level of agreement on the topics under consideration and potentially identify the most promising approaches to assessing CC affecting agricultural systems in the area and identify relevant and adequate response strategies. Design/methodology/approach – Stakeholder Delphi technique – its assessment is an interactive method of qualitative research used to facilitate the interactive participation of varied and conceivably hierarchical and antagonistic stakeholder groups. Findings – The most important result for the province is that the impact of climate change on agro-ecological landscapes (poverty and near river areas) is the duration of cold weather, more frequent and extreme. Moreover, Kendall’s W test gave a score of 0.547, which indicates a “strong” ...
TL;DR: In this paper, the authors used discriminant analysis to assess the relative importance of the discriminating characteristics (socioeconomic characteristics) through the utilization of the weights of the discriminant function and found that age, education, literacy level, farm type, location and gender were important predictors of how farmers perceive climate change and drought phenomena.
Abstract: Purpose – The purpose of this paper was to determine if there is an association between farmers’ socio-economic profile and their perception of climate change and related events (drought). Understanding of farmers’ perceptions of drought and climate change may assist in informing policy decisions and development of appropriate intervention strategies. Design/methodology/approach – Discriminant analysis was used to assess the relative importance of the discriminating characteristics (socio-economic characteristics) through the utilization of the weights of the discriminant function. Findings – Age, education, literacy level, farm type, location and gender were important predictors of how farmers perceive climate change and drought phenomena. Originality/value – Most of the studies carried out in the study area were largely descriptive and did not find the association between farmer socio-economic profiles and how they perceive climate change and drought events. This paper also uses discriminant analysis wh...
TL;DR: In this article, the authors investigate climate change perceptions and adaptation strategies in the communities of Morogoro region of Tanzania using quantitative interviews, surveys and focussed discussion groups to collect data capturing past and present trends in the catchment.
Abstract: Purpose – The purpose of this paper is to investigate climate change perceptions and adaptation strategies in the communities of Morogoro region of Tanzania. Climate change is a vital issue of global concern. Design/methodology/approach – Rain fall data trends collected from different meteorological stations in the region were useful in assessment of climate variability and change trends from the historical perspective. In addition, quantitative interviews, surveys and focussed discussion groups were used to collect data capturing past and present trends in the catchment, and reasons provided by 199 respondents from a total of six villages. The data were collected with the aid of trained research assistants and trained graduates selected from each of the randomly select villages. Findings – Significant differences in rainfall intensities have been recorded by use of feedback results from analysis of variance tests conducted. Major indicators of climate variability and change include: increased dry spells ...
TL;DR: In this article, a case study using Grande Riviere, Trinidad, was used to determine levels of climate change knowledge and awareness in the community and to highlight action needed for messages to be widely communicated.
Abstract: Purpose – This study aims to, using Grande Riviere, Trinidad, as a case study, determine levels of climate change knowledge and awareness in the community. Second, it seeks to provide new knowledge on appropriate techniques for developing climate change literacy. Third, it attempts to highlight action needed for messages to be widely communicated and policy implications for government agencies, non-governmental organisations, communication specialists and educators. Design/methodology/approach – A face-to-face questionnaire was administered to all households, focus group meetings were held and a training workshop was conducted. Findings – A key finding is that despite vulnerability to climate change, climate change literacy is low and is influenced by multiple variables such as household income, level of educational attainment, access to technology, governance structures and political commitment to communicating climate change. A major finding is that access to modern communication modes is limited and th...
TL;DR: In this paper, the authors examined the consumption behavior and effectiveness of coping mechanisms adopted by households living in disaster-prone regions of rural India to cope with climatic aberrations and extremes using household-level data.
Abstract: Purpose – This paper aims to examine the consumption behaviour and effectiveness of coping mechanisms adopted by households living in disaster-prone regions of rural India to cope with climatic aberrations and extremes using household-level data. In developing countries like India, poor households living in rural regions face risks to their livelihood due to climatic aberrations like deficient monsoon spells and rainfall gaps. Although these risks are covariate, the impact depends on location and the relative capacity of the people to cope with them. Design/methodology/approach – Using household-level data, this paper attempts to examine the consumption behaviour and effectiveness of coping mechanisms adopted by households living in these areas to hedge against the risks. A tobit and a multivariate probit model is used in the process. Findings – Based on the empirical analysis, and subject to the assumptions and the usual limitations of data, the findings suggest that households resort to consumption smoo...
TL;DR: In this article, the consequences of climate change for the future of armed forces and their presentation in national security documents are investigated, and a classification of potential future military roles and functions is derived from relevant literature, resulting in six military futures.
Abstract: Purpose – The paper aims to investigate the consequences of climate change for the future of armed forces and their presentation in national security documents. Design/methodology/approach – A classification of potential future military roles and functions is derived from relevant literature, resulting in six “military futures”. Frames are developed for these whose occurrence is counted in 53 authoritative documents on security policy and defense planning from 38 countries. Results are presented in descriptive statistics. Findings – The paper demonstrates that climate change has become an important issue for military planning. However, the directions in which it takes thinking about the future of armed forces differ widely. Among the six “military futures” identified, those linked to the function of disaster relief are most frequently found. However, the expansion of traditional military roles is also promoted. Rarer are suggestions for armed forces to became “greener” or “leaner”. In general, climate cha...
TL;DR: In this article, the authors explored how temperature and rainfall patterns determined maize and beans production in Hai District in Kilimanjaro Region, Tanzania, and found that maize yields were lower than perennial crops during the years of drought.
Abstract: Purpose – The purpose of this paper is to show how climatic change in Africa is expected to lead to a higher occurrence of severe droughts in semiarid and arid ecosystems. Understanding how crop productions react to such events is, thus, crucial for addressing future challenges for food security and poverty alleviation. Design/methodology/approach – The authors explored how temperature and rainfall patterns determined maize and beans production in Hai District in Kilimanjaro Region, Tanzania. Findings – Annual food crops were particularly sensitive to the drought and maize and beans yields were lower than perennial crops during the years of drought. The authors also report strong and significant association between maize and beans production with temperature and rainfall patterns. Practical implications – This study highlights how severe droughts can dramatically affect yields of annual crops and suggests that extreme climatic events might act as a major factor affecting agriculture production and food se...
TL;DR: Despite a lack of clear focus on climate change, the decentralization provisions and bottom-up practices within Nepal’s development policies and plans could be the entry points for mainstreaming CBA, but experience shows that decentralization alone is insufficient.
Abstract: Purpose – The purpose of this paper is to shed light onto the policy context of mainstreaming community-based adaptation (CBA) in Nepal. Scaling up CBA needs strong policy support. Design/methodology/approach – The content and processes of Nepal’s development policies and climate change policies and programmes were examined. The policy analysis was supported by a literature review, review of policy documents and interviews and discussions undertaken with policy-makers, practitioners and communities. Findings – Findings show that despite a lack of clear focus on climate change, the decentralization provisions and bottom-up practices within Nepal’s development policies and plans could be the entry points for mainstreaming CBA. However, experience shows that decentralization alone is insufficient because it benefits only a few institutions and individuals, while marginalizing the real beneficiaries. One of the policy conditions to mainstreaming CBA in development is to ensure that there are specific provisio...
TL;DR: In this paper, the authors design several methods for enforcing developed countries' responsibilities under the Green Climate Fund (GCF) under the historical responsibility (HR) principle, the ability to pay (AP) principle and the preference score compromises (PSC) approach.
Abstract: Purpose – The purpose of this paper is to design several methods for enforcing developed countries’ responsibilities under the Green Climate Fund (GCF). The GCF has been one of the core subjects of the world climate summits held under the United Nations Framework Convention on Climate Change. However, the development of the GCF has not progressed smoothly, and many concerns remain unresolved. Design/methodology/approach – This paper illustrates three approaches for financing the GCF that vary in terms of the relative weights accorded to environmental responsibility and economic capacity. These three methods include the historical responsibility (HR) principle, the ability to pay (AP) principle and the preference score compromises (PSC) approach (which is a combination of the HR and the AP principles). Findings – The empirical analysis demonstrates that the USA is the largest contributor to the GCF under the HR principle due to the volume of its historical emissions, whereas the European Union bears the gr...
TL;DR: In this article, the impact of climate change on yields and yield variances in major rainfed crops and measure possible changes in yields under projected climate changes in different agro-climatic zones of Tamil Nadu, India.
Abstract: Purpose – This paper aims to explore the impact of climate change on yields and yield variances in major rainfed crops and measure possible changes in yields under projected climate changes in different agro-climatic zones of Tamil Nadu, India. Although many empirical studies report the influence of climate change on crop yield, only few address the effect on yield variances. Even in such cases, the reported yield variances were obtained through simulation studies rather than from actual observations. In this context, the present study analyzes the impact of climate change on crops yield and yield variance using the observed yields. Design/methodology/approach – The Just-Pope yield function (1978) is used to analyze the impact of climate change on mean yield and variance. The estimated coefficient from Just-Pope yield function and the projected climatic data for the year 2030 are incorporated to capture the projected changes in crop yield and variances. Findings – By the year 2030, the yield of pulses is ...
TL;DR: In this article, the authors conducted an empirical analysis of the impact of climate change on maize, banana and durian production and estimated the determinants of adaptation to climate change and its corresponding effect on farm productivity.
Abstract: Purpose – This paper aims to assess the vulnerability of the farmer-respondents in Southern Philippines, specifically Region XI and XII, to climate change. Design/methodology/approach – This study conducted an empirical analysis of the impact of climate change on maize (Zea mays), banana (Musa sapientum) and durian (Durio zibethinus) production. Furthermore, it estimated the determinants of adaptation to climate change and its corresponding effect on farm productivity. The analysis used primary data from 541 farmer-respondents producing maize, banana and durian in the 6 provinces and 18 municipalities of the sample areas. Findings – Based on the probit estimate results, farmers adaptation decisions were influenced by information about future climate change conditions, social capital, access to formal extension and farmer-to-farmer extension. The author found from the stochastic frontier estimation in the production function that climate change adaptations exerted a significant impact on farm productivity....
TL;DR: This paper examined state adoption of climate action plans (CAPs) and investigated the factors driving the adoption of these climate policies in the states Design/methodology/approach, the framework that is formulated to explain the state climate actions involves four dimensions: climate risks, climate politics, climate economic and climate policy diffusions.
Abstract: Purpose – This paper aims to examine state adoption of climate action plans (CAPs) and investigates the factors driving the adoption of these climate policies in the states Design/methodology/approach – The framework that is formulated to explain the state climate actions involves four dimensions: climate risks, climate politics, climate economic and climate policy diffusions These hypotheses are tested with event history analysis on a panel data set on 48 US continental states from 1994 to 2008 Findings – This paper found empirical evidence to support climate politics, economics and policy diffusion explanations It also found that climate risks are not taken into account in states’ climate actions A comparison is conducted to compare the differences in state and local climate policymaking Originality/value – The paper investigates the motivations of state governments in adopting CAPs, and makes comparisons with local climate strategies It contributes to academic understanding of the multilevel gov
TL;DR: The authors report on an in-depth qualitative study that focuses on the convergence of the interpretive activities of knowing, living in and valuing the world in lay reasoning about climate change.
Abstract: Purpose – This paper aims to report on an in-depth qualitative study that focuses on the convergence of the interpretive activities of knowing, living in and valuing the world in lay reasoning about climate change Although awareness is growing that lay people interact with scientific knowledge about climate change in complex ways, relatively little is known about this interaction Much quantitative research on public attitudes to climate change does little to draw out the cognitive and experiential processes by which lay people arrive at understandings of climate change Design/methodology/approach – Through narrative analysis of qualitative interviews, this paper examines lay rationalities of climate change as a process of not only knowing the world (epistemology), but of being oriented towards the world (ontology) and valuing the world (axiology) Findings – The findings emphasise the extent of individual variation in lay interpretations of climate change, and their internal complexity Almost all part
TL;DR: In this paper, the authors address the cost of adaptation for rice using joint probability distribution of rainfall and crop prices, and find that the expected expected cost for not using these technologies has ranged from INR6,976 to 9,172/ha for SRI; INR4,123 7,764/Ha for AWD; and INR10,825 to 17,270/H for WI.
Abstract: Purpose – Researchers and policymakers are figuring out the adaptation technologies to cope with the changing climate. Adaptation strategies for crop production followed by the farmers at selected study locations had ranged from 6-30 per cent only, and this was mainly due to lack of awareness about the actual cost associated with adaptation and non-adaptation of these strategies. Design/methodology/approach – Hence, this study aims to address the cost of adaptation for rice using joint probability distribution of rainfall and crop prices. Findings – Cost of adaptation varied from INR2,389 to 4,395/ha for System of Rice Intensification (SRI); INR646 to 1,121/ha for alternate wetting and drying (AWD) and INR8,144 to 8,677/ha for well irrigation (WI), whereas expected cost for not using these technologies has ranged from INR6,976 to 9,172/ha for SRI; INR4,123 7,764/ha for AWD and INR10,825 to 17,270/ha for WI. Hence, promotion of the adaptation technologies itself will minimize the income losses to the farme...
TL;DR: In this article, a backward chronological linear model of climate change (precipitation and temperature) influence on water consumption was developed using software STATISTICA 10 to predict the impact of various climate change scenarios for domestic water consumption.
Abstract: Purpose – This paper aims to identify the priorities on water sector planning. The priorities are identified by comparing the climate change impact on water consumption and the impact of using domestic water illegally to irrigate the urban agricultural holdings in suburban areas. Design/methodology/approach – Metered water consumption in summer and winter in both urban and suburban areas was studied in Rafah city. A backward chronological linear model of climate change (precipitation and temperature) influence on water consumption was developed using software STATISTICA 10. The developed statistical relation was used to predict the impact of various climate change scenarios for domestic water consumption. Hence, four climate change scenarios were hypothesized – an increase in temperature by 1 and 20°C and a reduction in the rainfall by 10 and 20 per cent, respectively. Findings – The most influential climate change scenario was the increase of temperature by 20°C, which caused an increase of 1.4 per cent ...
TL;DR: In this article, the effects of climate change on harvestability for sugarcane growing regions situated between mountain ranges and the narrow east Australian coastline were investigated for the period of 2046-2065 under low (B1) and high (A2) emissions scenarios.
Abstract: Purpose – This study aims to investigate the effects of climate change on harvestability for sugarcane-growing regions situated between mountain ranges and the narrow east Australian coastline. Design/methodology/approach – Daily rainfall simulations from 11 general circulation models (GCMs) were downscaled for seven Australian sugarcane regions (1961:2000). Unharvestable days were calculated from these 11 GCMs and compared to interpolated observed data. The historical downscaled GCM simulations were then compared to simulations under low (B1) and high (A2) emissions scenarios for the period of 2046-2065. The 25th, 50th and 75th percentiles of paired model differences were assessed using 95 per cent bootstrapped confidence intervals. Findings – A decrease in the number of unharvestable days for the Burdekin (winter/spring) and Bundaberg (winter) regions and an increase for the Herbert region (spring) were plausible under the A2 scenario. Spatial plots identified variability within regions. Northern and so...
TL;DR: In this article, the impacts brought about by climate change to the food security in Saguday, Quirino in the Philippines were investigated and a framework for developing community food security was utilized which identified the need to mitigate and address inherent externalities in a community such as flooding due to climate change as necessary preconditions to attaining a food secure environment.
Abstract: Purpose – The purpose of this paper was to look into the impacts brought about by climate change to the food security in Saguday, Quirino in the Philippines. Design/methodology/approach – A framework for developing community food security was utilized which identified the need to mitigate and address inherent externalities in a community such as flooding due to climate change as necessary preconditions to attaining a food secure environment. The study highlighted Saguday’s risk to externalities using risk assessment and modelling. Findings – Data from literature reviews and agency reports were validated by key informant interviews of local and national officials and focus group discussions with different stakeholder groups. Originality/value – A modification of the Urban Food Security Planning Process developed by Taylor and Carandang (2010, 2011) was utilized to address the local government unit’s need to mitigate and manage the inherent geographical risks that Saguday has in relation to its agricultural...
