Clim.te v.riability and change are am.ng the biggest challenges of the 21st century. Like in m.ny other areas globally, the coastal com.unities of Tanzania hav. always been facing clim.tic v.riability at v.rious tim. scales. Using focus group discussion and a household surv.y, this study analyzes the perceptions of clim.te v.riability and change and the strategies for coping and adaptation by the selected coastal rural and peri-urban com.unities in Tanzania. The perception of clim.te v.riability and change is com.lem.nted with the tim.-series analysis of rainfall and tem.erature data from.Julius Nyerere International Airport m.t. station and Kisarawe using Instant Statistical Software. Results indicate that households are aware of clim.te v.riability and identify indicators of clim.te change and v.riability as being decreasing rainfall trends, increasing incidences of droughts, unpredictable rainfall patterns, disappearance of wetlands and failure to predict on-set of rainy season using traditional knowledge. Households prim.rily attribute reduced crop yields to changes in rainfall pattern and increasing incidences of drought leading to soil m.isture stress. The im.lications are that the agriculture dependent households are now food insecure. As a way of coping to the observ.d changes, the coastal com.unities am.ng others hav. shifted to production of high v.lue horticultural crops and use of forest resources. Nev.rtheless, the increased use of forest resources is threatening the existence of coastal forests and contributes to the decline of forest resources and disappearance of wildlife in the forest reserv.s. It is concluded that the com.unities studied are aware of clim.te issues as rev.aled from.perceiv.d indicators of clim.te v.riability and changes. The results from.statistical analysis of 30 years clim.tic data are consistent with com.unity’s perception of clim.te v.riability and change. The study recom.ends exam.ning the present coping strategies for the sus

Chrysikopoulos, Constantinos, v Khalifa Univ Dept Ind & Syst Engn POB 127788 Abu Dhabi U Arab Emirates Khalifa Univ.Abu Dhabi Elect Engn & Comp Sci Dept Abu Dhabi U Arab Emirates Khalifa Univ Dept Civil Infrastruct & Environm Engn POB 127788 Abu Dhabi U Arab Emirates Tech Univ.Crete Sch Chem & Environm Engn Khania 73100 Greece

Nowcasting and forecasting solar irradiance are v.tal for the optim.l prediction of grid-connected solar photov.ltaic (Pv. power plants. These plants face operational challenges and scheduling dispatch difficulties due to the fluctuating nature of their power output. As the generation capacity within the electric grid increases, accurately predicting this output becom.s increasingly essential, especially giv.n the random.and non-linear characteristics of solar irradiance under v.riable weather conditions. This study presents a nov.l prediction m.thod for solar irradiance, which is directly in correlation with Pv.power output, targeting both short-term.and m.dium.term.forecast horizons. Our proposed hybrid fram.work em.loys a fast trainable statistical learning technique based on the truncated-regularized kernel ridge regression m.del. The proposed m.thod excels in forecasting solar irradiance, especially during highly interm.ttent weather periods. A key strength of our m.del is the incorporation of m.ltiple historical weather param.ters as inputs to generate accurate predictions of future solar irradiance v.lues in its scalable fram.work. We ev.luated the perform.nce of our m.del using data sets from.both cloudy and sunny days in Seattle and m.dford, USA and com.ared it against three forecasting m.dels: persistence, m.dified 24-hour persistence and least squares. Based on three widely accepted statistical perform.nce m.trics (root m.an squared error, m.an absolute error and coefficient of determ.nation), our hybrid m.del dem.nstrated superior predictiv. accuracy in v.rying weather conditions and forecast horizons. A nov.l prediction m.thod for solar irradiance, targeting both short-term.and m.dium.term.forecast horizons, is proposed to im.rov. Pv.power production. The hybrid fram.work em.loys a fast trainable statistical learning technique based on the truncated-regularized kernel ridge regression m.del. Graphical Abstract
