An exploratory ultrasound survey of the rural population was done in Tamboul, Central Sudan. A total  of 651 subjects (381 female, 270 male) were examined for Cystic Echinococcosis. Subjects aged 5-80 years were selected randomly and examined for cystic echinococcosis  using a portable ultrasound scanner.. Six persons were diagnosed with CE (0.92%). Consecutively, a survey was made at the same location for Echinococcus spp. in  stray dogs during an ongoing rabies control campaign. 50 dogs (33 male, 17 female) were examined for the presence of Echinococcus using sedimentation and counting technique. An infection rate of 76% was reported with infection intensities ranging from 3 to 40,054 worms per dog. We also genotyped Echinococcus 71 isolates  from human (3),  intermediate host ( Camel, 35: cattle, 8) ) and definitive host (dogs, 15,:foxes, 10) using RFLP-PCR and LAMP techniques. All isolates analyzed were found to be the G6 genotype of E. Canadensis . The public-health impact of these finding are discussed in terms of the various species and genotypes of Echinococcus and the role of each in human health.

  • Effect of Compost and Green Manure on Growth and Yeild of Sweet Pepper (Capsicum annuum L.)

 

   Field experiments were conducted at the Experimental Farm of the Faculty of Agricultural Sciences, University of Gezira, Sudan in seasons 2010/2011. The objectives were to investigate effect of compost and green manure on growth and yield of sweet pepper (Capsicum annum L.). At the first experiment, compost was applied at 0, 10 and 20 ton ha-1   in RCBD, while, at the second experiments green manure was applied at 0 or normal green manure. in split plot design with three replicates for both. Data on growth and yield parameters were measured and subjected to analysis of variance. Means were separated by using Duncan’s Multiple Range Test at P ≤ 0.05.  The results showed that, application of compost and green manure improved soil properties and hence growth and yield of sweet pepper. The study showed that application of compost gave better results than application of green manure when sweet pepper growth and yield and some soil properties are considered. This study showed that, application of compost and/or green manure into the Gezira soil improved chemical and physical conditions, thus improving soil fertility and crop productivity. Such cultural practices reduce cost of production of horticultural crops such as sweet pepper and maintain a friendly and an environmentally sound agriculture. The study recommends the use of organic manure such as compost and/or green manure for production of crops grown especially for export such as green pepper.

  • Small Farmers’ Perception on Climate Change Risk at the Blue Nile State, Sudan
Abstract The present study aimed at investigating small farmers’ perception on climate changes impact on natural vegetation and crop production at the Blue Nile state, focusing on two localities (El-Damazine and Al-Tamadon) during the years 2010-2011. Eleven villages (18655 households) were surveyed. About 97% of the respondents suffered from water scarcity, with 51% stating surface water depletion especially during summer when temperatures were high and rainfall was low. They related problems of water scarcity to population growth and concentration of animals around water points. Over 50% of the interviewed households attributed the decrease in grazing areas and animal death to fluctuations in rainfall, whereas 96% related change in vegetation cover to insufficient rainfall, soil fertility and disappearance of water courses and recurrent droughts. Crop failure was related to rainfall and appearance of weeds (96%). It was concluded that most of small scale farmers are fully aware of climate change impact on vegetation cover and crop production attributable to rainfall fluctuation and soil infertility. Deterioration in water availability and plant cover were also attributed to human effect. Keywords:Climate change, natural vegetation, water availability, human effect

  • Impact of climate change on natural resources at ELDamazine and AT -Tamadon localities Blue Nile state
Accepted 04 February 2015 This study was carried out to estimate the effect climatic changes of natural vegetation at the Blue Nile state, focusing on two selected localities El-Damazine and Al-Tamadon during the years 2010 - 2011. Remote sensing techniques were used for detection of changes for the years (from 1972 to 2011). The data analysis adopted the descriptive Statistical Package for Social Science (SPSS, version 16). The results obtained showed that fluctuations in rainfall through the years (from 1972 to 2011) depicted a general declining pattern while that of temperature tended to increase. This was confirmed by secondary data obtained from meteorological authority. Higher fluctuations in areas of vegetation cover could be detected for the years (from 1973 to 2011). However, rock and bare lands showed small changes. The increase in vegetation cover in most recent years was correlated with the appearance and disappearance of some species. Deterioration of tree cover was due to indiscriminate cut wood around the city and due the horizontal expansion of mechanized agriculture It could be concluded that rain fed agriculture is inherently sensitive to climate conditions and is one of the most vulnerable sectors to the risks and impact of climate change mainly determined by rainfall and warming of air temperatures. Impact of climate change showed shift in the ecosystem causing appearance and disappearance of plant species, other land types (bare and rock lands) were not significantly affected
