Climate change impacts have gained great attention to be studied in various fields. In this paper, an investigation of rainfall pattern change is performed using three statistical methods, i.e., simple linear regression, t-test, and Mann-Kendall’s test. The analysis is performed at 10- and 20-year time scales of daily, monthly, and annual rainfall in Flores Island, a dry region in Indonesia. In general, an increasing monthly rainfall trend is detected in the rainy season (October – April) at a 20-year period, using all three methods. Specifically, a significant increasing trend in March 1989 – 2008 is observed, and it contributes to the significant increasing trend of annual rainfall.  The findings presented in this paper should be an alert for potential climate change impacts in the region. The positive consideration of having more rainfall in a dry region might turn into a negative reality when adaptation measures are not well-prepared.

Bhadar is one of the major rivers of Kathaiwar (Saurashtra) peninsula in Gujarat, India. It originates near Vaddi (Aniali Village) about 26 km north – west of Jasdan in Rajkot district of the state of Gujarat, India at an elevation of 261 m above mean sea level. Impact assessment of climate change over Bhadar river basin is carried out using two statistical methods of Trend Analysis i.e. linear Regression, and Innovative Trend method. Effect of climate change on annual rainfall and monthly rainfall are studied. Results show that there is an overall increase in annual rainfall trend in Bhadar river basin/catchment area at all stations except one station. The results for monthly rainfall show that the rainfall in the month of July and September shows increasing trend at all stations. The results obtained using Linear Regression and Innovative Trend method are found to be consistent.

AbstractUnderstanding how potential climate change will affect availability of water resources for citrus production globally is needed. The main goal of this study is to investigate impacts of potential future climate change on citrus irrigation requirements (IRR) in major global citrus producing regions, e.g., Africa, Asia, Australia, Mediterranean, Americas. The Irrigation Management System (IManSys) model was used to calculate optimum IRR for the baseline period (1986–2005) and two future periods (2055s and 2090s) subject to combination of five and seven temperature and precipitation levels, respectively. Predicted IRR show significant spatio-temporal variations across study regions. Future annual IRR are predicted to globally decrease; however, future monthly IRR showed mixed results. Future evapotranspiration and IRR are projected to decrease by up to 12 and 37%, respectively, in response to increases in CO2 concentration. Future citrus canopy interception and drainage below citrus rootzones are expected to slightly increase. Annual rainfall changes are negatively correlated with changes in IRR. These projections should help the citrus industry better understand potential climate change impacts on citrus IRR and major components of the water budget. Further studies are needed to investigate how these potential changes in CO2 concentration, temperature, evapotranspiration, rainfall, and IRR will affect citrus yield and its economic impact on the citrus industry.

Abstract. A probabilistic assessment of climate change and related impacts should consider a large range of potential future climate scenarios. State-of-the-art climate models, especially coupled atmosphere-ocean general circulation models and Regional Climate Models (RCMs) cannot, however, be used to simulate such a large number of scenarios. This paper presents a methodology for obtaining future climate scenarios through a simple scaling methodology. The projections of several key meteorological variables obtained from a few regional climate model runs are scaled, based on different global-mean warming projections drawn in a probability distribution of future global-mean warming. The resulting climate change scenarios are used to drive a hydrological and a water management model to analyse the potential climate change impacts on a water resources system. This methodology enables a joint quantification of the climate change impact uncertainty induced by the global-mean warming scenarios and the regional climate response. It is applied to a case study in Switzerland, a water resources system formed by three interconnected lakes located in the Jura Mountains. The system behaviour is simulated for a control period (1961–1990) and a future period (2070–2099). The potential climate change impacts are assessed through a set of impact indices related to different fields of interest (hydrology, agriculture and ecology). The results obtained show that future climate conditions will have a significant influence on the performance of the system and that the uncertainty induced by the inter-RCM variability will contribute to much of the uncertainty of the prediction of the total impact. These CSRs cover the area considered in the 2001–2004 EU funded project SWURVE.

This study is based on a farm house hold survey (818 households) collected from 4 districts of drought prone region of central India and examines that how farmers perceive the climate change and adaptation strategies adopted over the past few decades. Nearly, 80.9%, 93.6% and 95.2% farmers’ perceived that the average temperature has increased, rainfall has decreased and occurrence of drought is more frequent, respectively during last 25–30 years. A significant decreasing trend was observed in annual rainfall at all the studied locations with a rate of 2.1 to 5.8 mm year–1. In most of the locations both maximum and minimum temperature showed an increasing trend during winter season (July-October) in the range of 0.8 to 1.2 and 0.4–1.5ºC per 100 year, respectively. However, only two locations viz., Jhansi and Banda district showed increasing trend in maximum temperature in the range of 0.8 to 2.3oC per hundred years during rainy season. This study revealed that the perceptions of rural farmers on climate change and variability are consistent with the climate trend analysis. Econometric model suggested a positive influence of age, agriculture experience, educational qualification, size of land holding, adequate access to credit facility and crop insurance, intermittent dry spell and adequate extension services on climate change perceptions and adaptation. The results further revealed that 69.8% respondent have implemented adaptation measures in response to dry spell. Furthermore, analysis showed that agriculture experience, educational qualification and intermittent dry spell and access to extension services are the key factors for adoption of various adaptation strategies particularly, irrigations scheduling, use of high yielding improved varieties, pesticides and change of planting date. Inadequate availability of irrigation resources and frequent drought as well as intermittent dry spells were considered as the most critical barriers for adaptation measures to climate change by farmers.

As users of forest products and guardians of traditional knowledge, women have always been involved in forestry. Nevertheless, their access to forest resources and benefits and participation in forest management is limited compared to mens despite the fact that trees are more important to women, who depend on them for their families food security, income generation and cooking fuel. This guide aims to facilitate the incorporation of a gender lens in climate change mitigation and adaptation operations in forests, with special attention to those framed in REDD. This guide addresses four themes value chains, environmental payment schemes, firewood and biodiversity that relate directly to 1) how climate change impacts affect women in the forest and 2) how mitigation and adaptation measures affect womens access to resources and benefits distribution.

Climate change is already being felt in Europe, unequivocally affecting the regions’ geo-structures. Concern over this is rising, as reflected in the increasing number of studies on the subject. However, the majority of these studies focused only on slopes and on a limited geographical scope. In this paper, we attempted to provide a broader picture of potential climate change impacts on the geo-structures in Europe by gathering the collective view of geo-engineers and geo-scientists in several countries, and by considering different geo-structure types. We also investigated how geo-structural concerns are being addressed in national adaptation plans. We found that specific provisions for geo-structural adaptation are generally lacking and mainly come in the form of strategies for specific problems. In this regard, two common strategies are hazard/risk assessment and monitoring, which are mainly implemented in relation to slope stability. We recommend that in future steps, other geo-structures are likewise given attention, particularly those assessed as also potentially significantly affected by climate change. Countries considered in this study are mainly the member countries of the European Large Geotechnical Institutes Platform (ELGIP).

Abstract Mitigation of climate change and adaptation to its effects manifested in increasingly extreme meteorological phenomena are one of the most important contemporary global challenges. In the face of new hazards, numerous measures are taken to adapt environmental components and ventures to climate change, such as the reclamation of degraded areas – recognized as a key adaptation and mitigation action. The success and the property of selecting these measures, including reclamation, requires a detailed recognition of the risk of occurrence of various hazards and of the severity of their consequences in a given area. The study assessed the risk of the climate change impacts on the post-mining area and based on its results an optimal method of reclamation of the “Brzeziny” gravel pit was proposed, aimed at the maximum adaptation of the area to the occurrence of potential climate events. The risk analysis was based on elements of the common risk assessment methodology (CRAM) and enriched with elements of the analytic hierarchy process method (AHP). Moreover, the event tree analysis (ETA) logic technique was used to assess the proposed adaptation measures at the reclamation stage.

Este artigo descreve a experiência da coalizão Adapta Sertão na experimentação e disseminação de sistemas produtivos que possam tornar o agricultor familiar do Semiárido mais resiliente aos impactos da variação climática atual e da mudança do clima no futuro. Durante as experimentações, a coalizão teve que enfrentar várias barreiras ligadas à falta de integração entre políticas públicas existentes e projetos pilotos em comunidades locais. Hoje, a adaptação à mudança do clima não está sendo considerada na implementação de obras hídricas de pequeno e médio porte, que são de grande importância porque, geralmente, conseguem beneficiar as faixas de população mais pobres e mais suscetíveis aos impactos climáticos. As experiências mostram que é preciso desenvolver, com urgência, políticas públicas inovadoras que consigam integrar o acesso à água com a disseminação de tecnologias de adaptação e de sistemas produtivos mais resilientes à seca.  Palavras - chave: medidas de adaptação, agricultura familiar, semiárido, tecnologia.  The experience of the Adapta Sertão Coalition in Disseminating Climate Change Adaptation Technologies and Strategies for Family Farmers in Semi Arid Brazil  ABSTRACTThis paper describes the experience of the Adapta Sertão coalition in testing and experimenting production systems that have the potential to make small farmers of semi-arid Brazil more resilient to current and future climate change impacts. During the different testing, the coalition had to overcome several barriers linked to a lack of integration between current public policies. For example, today climate change is not considered in the design and implementation of small and medium hydraulic infrastructures. This limits the benefits to the target groups (small farmers) that are more likely to be affected by climate change. The experiences show that it is urgent and necessary to develop public policies to better integrate access to water, dissemination of climate resilient technologies and implementation of production systems more adequate to the semi arid conditions.  Keywords: adaptation measures, family farming, semi-arid, technology.

Impacts Of Climate Change

Abstract. The overall agricultural system in the Nile Delta region is considered as one of the highest intensive and complicated agriculture systems in the world. According to the recent studies, the Nile Delta region is one of the highly vulnerable regions in the world to climate change. Sea level rise, soil and water degradation, undiversified crop-pattern, yield reduction, pests and disease severity, and irrigation and drainage management were the main key factors that increased vulnerability of the agriculture sector in that region. The main objective of this study is to conduct a community-based multi-criteria adaptation assessment in the Nile Delta using a preset questionnaire. A list of possible adaptation measures for agriculture sector was evaluated. The results indicated that the Nile Delta growers have strong perceptions to act positively to reduce the impacts of climate change. They reflected the need to improve the their adaptive capacity based on clear scientific message with adequate governmental support to coop with the negative impacts of climate change.
