Abstract:

Botswana is a landlocked country situated in central southern Africa (approximately 20 -28° E and 18 - 26° S). It is a water-stressed country. Mean Annual Rainfall (MAR) ranges from under 140 mm to just under 600 mm. The average number of rain days receiving 5mm or more ranges from 18 to 26 days per year [1]. This means the average number of rainless days ranges from 339 to 357 days per year (Figure 1).

Abstract:

Abstract Biocrust sustainability relies on dew and rain availability. A study of dew and rain resources in amplitude and frequency and their evolution is presented from year 2001 to 2020 in southern Africa (Namibia, Botswana, South Africa) where many biocrust sites have been identified. The evaluation of dew is made from a classical energy balance model using meteorological data collected in 18 stations, where are also collected rain data. One observes a strong correlation between the frequency of dew and rain and the corresponding amplitudes. There is a general tendency to see a decrease in d

Abstract:

Abstract Smallholder farmers are particularly vulnerable to the effects of climate change and variability in semiarid contexts. Despite the limited adaptation options often used and the largely subsistence agriculture practiced, studies have shown that smallholders have accumulated local knowledge about changes in climatic conditions. Farmers with field experience and an extensive stay in three sites in Palapye, eastern Botswana, were interviewed. This study related farmers’ perceptions of changes in climate with results from analysis of climate data. Major changes perceived are a reduction in

Abstract:

This paper presents perception of farmers in terms of adaptation and mitigation to climate change in Kgalagadi-North District. The study used qualitative survey method and results are derived from purposively selected interviews using semi-structured questionnaire. The research focused on participants who were aged 50 years and above. Data were summarized and analysed qualitatively using descriptive statistics. Farmers’ perceptions showed that frequent wildfire was major cause of climate change. Farmers further mentioned that they were affected by irregular rainfall, increased temperature and

Abstract:

Eight microwave links operating at frequencies ranging from 6 to 8 GHz and with path lengths ranging from 5.7 to 37.4 km traversing the city of Seoul, Korea are used to detect rainfall and estimate path-averaged rainfall rates. Rainfall detection using rain-induced attenuation (dB) was validated by rain detectors installed at automatic weather stations, and the results confirmed that microwave links can be used to detect rainfall with an accuracy ≥80%. The power-law R-k relationships between rain-induced specific attenuation, k (dB km−1), and the rainfall rate, R (mm h−1), were established and

Abstract:

The interannual variability of traditional, rainfed agricultural production of Botswana, a country with a typical semi-arid climate, is almost completely accounted for by the quality of the rainy season. It appears that the variability of the national cattle death ratio, total planted area and crop yield are, for more than 95% accounted for by rainy season conditions. As a result, also the nutritional state of the population highly correlates with rainfall. Despite the severe droughts of 1978/79and1985/86, farmers were not discouraged to practice agriculture: in fact, crop production shows a s

Abstract:

South Jakarta has the highest rainfall concentration and the most flood location in Jakarta. Therefore, an urban drainage system is needed to control surface water so flood can be prevented. This research aims to support the urban drainage system planning by determining rainfall intensity based on three methods, those are Van Breen, Bell Tanimoto, and Hasper der Weduwen. The most suitable method will be selected by comparing the value of rainfall intensity with Talbot, Sherman, and Ishiguro approach. This research reveals that the most suitable method is the Van Breen Method with the Talbot eq

Abstract:

Abstract The Tropical Rainfall Measuring Mission–based National Aeronautics and Space Administration Goddard Multisatellite Precipitation Analysis (MPA) product is used to quantify the rainfall distribution in tropical cyclones that made landfall in the United States during 1998–2004. A total of 37 tropical cyclones (TC) are examined, including 2680 three-hourly MPA precipitation observations. Rainfall distributions for overland and overocean observations are compared. It is found that the TC rainfall over ocean bears a strong relationship with the TC maximum wind, whereas the relationship for

Abstract:

AbstractTRMM satellite 3B42 rainfall estimates for 133 landfalling tropical cyclones (TCs) over China during 2001–15 are used to examine the relationship between TC intensity and rainfall distribution. The rain rate of each TC is decomposed into axisymmetric and asymmetric components. The results reveal that, on average, axisymmetric rainfall is closely related to TC intensity. Stronger TCs have higher averaged peak axisymmetric rain rates, more averaged total rain, larger averaged rain areas, higher averaged rain rates, higher averaged amplitudes of the axisymmetric rainfall, and lower amplit
