Climate change and people’s perception on such changes are analysed for the Khudi Watershed in Western Nepal. Climate change trends in the western hilly region of Nepal were investigated focusing on two major climatic indicators: surface air temperature and rainfall. Further, community’s perceptions on climate change impacts were analysed. We found considerable warming in the study area with a mean temperature increase of 0.18°C decade-1. Annual rainfall is varying with prolonged dry periods. During monsoon season short but intense rainfall events were observed. Local denizens have also experienced these changes and think that weather related changes are affecting their livelihood practices with increased weather related disasters, less agricultural yield, and imbalances in socio-economic behavior.  HYDRO Nepal JournalJournal of Water, Energy and EnvironmentIssue: 17, July 2015

Zimbabwe is a semi-arid country reliant on regular rains (November-April). Mean annual rainfall is low, and many rivers in the drier parts of the country are not perennial. In the small-scale horticultural sector, irrigation becomes handy. Rainfall exhibits spatial and temporal variability. This scenario is characterized by shifts in the onset of rains, increases in frequency and intensity of heavy rainfall events, increases in the proportion of low rainfall years, decreases in low-intensity rainfall events, and increases in the frequency and intensity of mid-season dry spells. Drought have increased in frequency and intensity. Agriculture is the main source of income for most smallholder farmers who depend on rain-fed cropping and livestock rearing. Adaptation of agriculture to climate variability and change impacts is vital for livelihood. To develop appropriate strategies and institutional responses to climate change adaptation, a clear understanding of climate change impacts on smallholder farmers at farm-level is vital.

Agriculture and climate change are internally correlated with each other in various aspects, as climate change is the main cause of biotic and abiotic stresses, which have adverse effects on the agriculture of a region. The land and its agriculture are being affected by climate changes in different ways, e.g., variations in annual rainfall, average temperature, heat waves, modifications in weeds, pests or microbes, global change of atmospheric CO2 or ozone level, and fluctuations in sea level. The threat of varying global climate has greatly driven the attention of scientists, as these variations are imparting negative impact on global crop production and compromising food security worldwide. According to some predicted reports, agriculture is considered the most endangered activity adversely affected by climate changes. To date, food security and ecosystem resilience are the most concerning subjects worldwide. Climate-smart agriculture is the only way to lower the negative impact of climate variations on crop adaptation, before it might affect global crop production drastically. In this review paper, we summarize the causes of climate change, stresses produced due to climate change, impacts on crops, modern breeding technologies, and biotechnological strategies to cope with climate change, in order to develop climate resilient crops. Revolutions in genetic engineering techniques can also aid in overcoming food security issues against extreme environmental conditions, by producing transgenic plants.

Climate change is now recognized as one of the most serious challenges facing the world– its people, the environment and its economies. Rural people are more vulnerable to the effects of climate change due to its high dependence on climate-sensitive sectors like glaciers, agriculture and forestry, and its low financial adaptive capacity. This study was carried out with the aim of assessing and documenting vulnerability and adaptation strategies of forest-dependent people to climate change effects in Mid-hills of Nepal. Primary data were collected from household survey, interview with key informants, and focused group discussion. The results showed that the average annual rainfall was decreasing at the rate of 18.02 mm whereas the average annual mean temperature was increasing at the rate of 0.07°c per year. The major climatic hazards, of the study area, identified were long drought and landslide. The chi-square test shows that the poor forest-dependent people are more vulnerable to long drought, landslide and floods as compared to the rich rural people. Indigenous adaptation practices such as cultivation of vegetables and other crops that are less susceptible to droughts, and rearing of hybrid-varieties of livestock are mostly used to cope with climate change impacts. The results indicate that 15% of the respondents have changed their cropping pattern from paddy to off-seasonal vegetables crops because of more income from vegetable farming. Raising awareness and sharing information as well as increasing income from farming among the locals by applying new technologies should be done in order to build their capacity to cope with climate change impact.Banko Janakari, A Journal of Forestry Information for NepalVol. 25, No. 1Page: 55-62

Climate change has impacted all phenomena in the hydrologic cycle, especially extreme events. General circulation models (GCMs) are used to investigate climate change impacts but because of their low resolution, downscaling methods are developed to provide data with high enough resolution for regional studies from GCM outputs. The performance of rainfall downscaling methods is commonly acceptable in preserving average characteristics, but they do not preserve the extreme event characteristics especially rainfall amount and distribution. In this study, a novel downscaling method called synoptic statistical downscaling model is proposed for daily precipitation downscaling with an emphasis on extreme event characteristics preservation. The proposed model is applied to a region located in central Iran. The results show that the developed model can downscale all percentiles of precipitation events with an acceptable performance and there is no assumption about the similarity of future rainfall data with the historical observations. The outputs of CCSM4 GCM for two representative concentration pathways (RCPs) of RCP4.5 and RCP8.5 are used to investigate the climate change impacts in the study region. The results show 40% and 30% increase in the number of extreme rainfall events under RCP4.5 and RCP8.5, respectively.

Potential Climate Change

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.

In this paper the rainfall features at different raingauge stations of Goa state have been studied for the period of 30 years. The statistical parameters such as mean monthly rainfall, Standard Deviation and Coefficient of Variation have been computed for each raingauge station of Goa. Some heavy rainfall events during the period have also been studied. The study shows the significant rising trend of rainfall towards the eastern parts of Goa. Goa experiences an average rainfall of about 330 cm annually and around 90% of annual rainfall occurs during southwest monsoon season i.e. (June to September). Studies revealed that most of heavy rainfall events caused due to active off-shore trough and low pressure systems formed over southeast Arabian Sea. It has also come out from the study that the orography of Goa plays an important role in rainfall distribution. Valpoi receives maximum rainfall due to its orographic effect.

Climate change is a complex and cross-cutting problem that needs an integrated and transformative systems approach to respond to the challenge. Current sectoral approaches to climate change adaptation initiatives often create imbalances and retard sustainable development. Regional and international literature on climate change adaptation opportunities and challenges applicable to southern Africa from a water-energy-food (WEF) nexus perspective was reviewed. Specifically, this review highlights climate change impacts on water, energy, and food resources in southern Africa, while exploring mitigation and adaptation opportunities. The review further recommends strategies to develop cross-sectoral sustainable measures aimed at building resilient communities. Regional WEF nexus related institutions and legal frameworks were also reviewed to relate the WEF nexus to policy. Southern Africa is witnessing an increased frequency and intensity in climate change-associated extreme weather events, causing water, food, and energy insecurity. A projected reduction of 20% in annual rainfall by 2080 in southern Africa will only increase the regional socio-economic challenges. This is exacerbating regional resource scarcities and vulnerabilities. It will also have direct and indirect impacts on nutrition, human well-being, and health. Reduced agricultural production, lack of access to clean water, sanitation, and clean, sustainable energy are the major areas of concern. The region is already experiencing an upsurge of vector borne diseases (malaria and dengue fever), and water and food-borne diseases (cholera and diarrhoea). What is clear is that climate change impacts are cross-sectoral and multidimensional, and therefore require cross-sectoral mitigation and adaptation approaches. In this regard, a well-coordinated and integrated WEF nexus approach offers opportunities to build resilient systems, harmonise interventions, and mitigate trade-offs and hence improve sustainability. This would be achieved through greater resource mobilisation and coordination, policy convergence across sectors, and targeting nexus points in the landscape. The WEF nexus approach has potential to increase the resilience of marginalised communities in southern Africa by contributing towards attaining the Sustainable Development Goals (SDGs 1, 2, 3, 6, 7, and 13).

National Perspective

Climate is a measure of changes in meteorological variables. Sudden changes arise due to increasing deforestation, pollution, population, depletion of natural resources, global warming and industrialization etc. Uneven monsoon and irregular rainfall distribution causes great variations in climatic conditions which cause disasters; drought and flood. During monsoon season, flood occurs in several river basins of U.P and U.K states. According to Indian Meteorological Department, the average annual rainfall in U.P and U.K is more than other states; 100-120 cm and 120-400 cm respectively. Uttarakhand is among one of the highest rainfall states of India. Sharda river; a tributary of river Ganga overflows many times, causes flood in surrounded regions. Sharda-Yamuna link (S-Y) is one of the proposed links of National Perspective Plan to minimize flood in U.P and U.K states and drought in western parts such as Haryana, Rajasthan, and Gujarat of the country. Excess water will be transferred through S-Y link towards the drought regions of India. Approx 11,680 m3 of surplus water is estimated to transfer from river Sharda to river Yamuna to avoid flood in U.P and U.K states. The lining of the link passes through two states Uttarakhand and Uttar Pradesh. The S-Y may also help in maintaining the water balance in its Enrouted and Command regions. This paper highlights the climate change, flood and drought disaster issues and role of proposed Sharda-Yamuna link.
