The prime need of this world is that the simplest agriculture which decides the event of each country because the survival of the individual is completely obsessed with farming and its best production. Climate changes are in response to changes within the hydrosphere, biosphere, and other atmospheric and interacting factors. Human activities driven by demographic, economic, technological, and social changes have a big impact on activity. The climate influences the incidence further as the temporal and spatial distribution of plant diseases. the foremost factors that control the growth and development of diseases are temperature, light, and water. Climate affects all life stages of the pathogen and host and poses a challenge to many pathosystems. The environmental change, especially when combined with the pathogen and host introductions, may cause unprecedented effects.

Climate change will have a significant effect on crop water requirement (ETc). The spatial and temporal variations of water requirement of maize under climate change are essential elements when conducting a global water security assessment. In this paper, annual reference crop evapotranspiration (ET0) and the crop water requirement of maize were calculated by the single crop coefficient method. The crop water surplus deficit index (CWSDI) and coupling degree of ETc and effective precipitation (Pe) were calculated to analyze the relationship between ETc, ET0, and Pe. The result shows that maize average annual ET0, ETc, and precipitation were 552.97, 383.05, and 264.97 mm, respectively. Moreover, ET0, ETc, and Pe decreased by 3.28, 2.56, and 6.25 mm every decade from 1960 to 2015. The ETc decreased less than Pe did, which led to the decreasing of both CWSDI and the coupling degree of ETc and Pe. The tendency of ET0, ETc decreased first and then increased, while Pe and CWSDI increased first and then decreased, from west to east of the Heilongjiang Province. In addition, the highest ET0, ETc, and lowest CWSDI and Pe were found in the western part of Heilongjiang Province. This study indicated that even though the water deficit in the western region was alleviated and the water deficit in the eastern region grew gradually serious from 1960 to 2015, the drought situation in western Heilongjiang Province should still be taken seriously.

The TRUST project is funded by the European Commission’s by the Life+ Programme. The aim of the TRUST project is the identification of the adaption and mitigation measures to counteract the impacts of climate change on the groundwater of the Upper Plain in the Veneto and Friuli region in North-Eastern Italy. The TRUST project aims at implementing a water balance modelling tool to support institutions in formulating sustainable water management planning policies and best practices. This paper reviews the development and application of the tools for the groundwater balance model that simulate the groundwater deficit. Projections on the water deficit as a function of Climate Change have used future precipitation and evapotranspiration patterns derived from climate simulations (SRES-IPCC scenarios A1B and A2) of the Mediterranean region for the 20th and 21st centuries. Model outputs showed that a significant part of future water deficit might be recovered with Managed Aquifer Recharge that will permit the groundwater management preventing the climate change effect.

Climate is one of the major factors that govern the distribution of tree species. Climate change has already affected the growth, structure and distribution of trees and woodlands. Global climate change projections are wetter winters, drier summers and significance changes in temperature regimes in the next few decades. The main objective of this study was to experimentally demonstrate the effects of decline in summer rainfall, as predicted by UKCP09/IPCC, on height and diameter growth in two co-occurring silver birch (Betula pendula Roth) and downy birch (Betula pubescens Ehrh) and provide further understanding of the changes in growth and development in response to a decrease in water availability. One-year-old seedlings were grown in a temperature-controlled greenhouse for eight weeks in a split-plot experimental design. Their height and diameter were measured and analyzed. Result showed that plant height and diameter was significantly reduced with increased water stress. B. pendula showed higher physiological traits indicating that this species can perform better than B. pubescensin water-deficit conditions.

Effects Of Temperature

The temperature size rule (TSR) is the tendency for ectotherms to develop faster but mature at smaller body sizes at higher temperatures. It can be explained by a simple model in which the rate of growth or biomass accumulation and the rate of development have different temperature dependence. The model accounts for both TSR and the less frequently observed reverse-TSR, predicts the fraction of energy allocated to maintenance and synthesis over the course of development, and also predicts that less total energy is expended when developing at warmer temperatures for TSR and vice versa for reverse-TSR. It has important implications for effects of climate change on ectothermic animals.

The Impact

<p><em>Climate change has been influencing rainfall pattern so that it would be necessary to see the impact of that changed on tea plantation. The experimental area coverage lowland (600 m asl), midland (800-1000m asl) and highland (&gt;1.000 m asl) tea plantation and each altituted represented by three tea estate in West Java. The rainfall data collected since 2005 up to 2014 from each estate and water deficit has been count through the method develop by Wijaya (1996). The results showed that the rainfall pattern has been changed by La-Nina and El-Nino during 2005-2014 in tea estate either in lowland, midland or highland in the last decade. The climate change caused  rainfall decreasing and increasing on dry month (the rainfall &lt; 100 mm). Eventhough on 2009 there is an significantly increasing of the rainfall but after 2009 until 2014, the rainfall tend to decrease. After El-Nino on late 2009 and early 2010, lowland tea estate on Subang Regency facing water deficit until 5 months with R (defisit water index) far below 1 even there is no El Nino. The tea plantation at midland area (Cianjur Regency) facing 5 months water deficit per year, but the R index close to 1. While in highland tea plantation (Bandung Regency), the water deficit only happend on certain month on certain year although there is a month with zero rainfall. Water deficit could be happend because of runoff on soil surface stimulate by low ability of soil to keep the water.</em></p>

AbstractSpoljar A., Kisic I., Peremin Volf, T., Kamenjak D., Kaucic D.: Influence of climate change on soil water regime in Koprivnica-Krizevci County. Ekológia (Bratislava), Vol. 33, No. 2, p. 178-187, 2014.The influence of climate change on soil water regime was investigated in the area of Koprivnica- -Krizevci County (Republic of Croatia). Water balance calculations were done for three climatic stations using Thornthwaite and Palmer water balance methods. In the 18-year period (from 1991 to 2008), compared with the previously observed 30-year period (from 1961 to 1990), the increase in average mean annual temperature was 1°C. Regarding the global warming, there was an increase in plant water potential during the investigated period. Compared with the previous period and according to Thornthwaite and Palmer methods, there was an increase in water deficit. Negative linear trend in precipitation was detected for all climate stations in the investigated area (p > 0.05) as well as positive linear trend in mean annual temperature (p < 0.05). The calculation of linear trend in water deficit in soil, according to Thornthwaite method, shows that by the year 2020 there could be an increase in water deficit by an average of 13 mm (p > 0.05), whereas according to the Palmer method there could be an increase by an average of 9 mm (p < 0.05 only for the climate station in Krizevci).

Mobile phone ownership has seen a steady increase in Kenya in the last five years and currently stands at 28.08 million mobile phone subscribers spread throughout the country. With poor road infrastructure, the mobile phone has become invaluable in reaching many people and can be useful in broadcasting information such as in education, health, agriculture and many other sectors. Previous survey and analysis indicates that implementation of technology is one of the key effectors of turnaround of rural economies. The main challenge that lies ahead is one of strengthening the innovation capabilities of African in order to be able to successfully address negative impacts caused by climate change and achieve broader economic growth and development.
