Agriculture production in Nigerien rural areas mainly depends on weather variability. Weather forecasts produced by national or international bodies have very limited dissemination in rural areas and even if broadcast by local radio, they remain generic and limited to short-term information. According to several experiences in West Africa, weather and climate services (WCSs) have great potential to support farmers’ decision making. The challenge is to reach local communities with tailored information about the future weather to support strategic and tactical crop management decisions. WCSs, in West Africa, are mainly based on short-range weather forecasts and seasonal climate forecasts, while medium-range weather forecasts, even if potentially very useful for crop management, are rarely produced. This paper presents the results of a pilot initiative in Niger to reach farming communities with 10-day forecasts from the National Oceanic and Atmospheric Administration—Global Forecast System (NOAA-GFS) produced by the National Centers for Environmental Prediction (NCEP). After the implementation of the download and treatment chain, the Niger National Meteorological Directorate can provide 10-day agrometeorological forecasts to the agricultural extension services in eight rural municipalities. Exploiting the users’ evaluation of the forecasts, an analysis of usability and overall performance of the service is described. The results demonstrate that, even in rural and remote areas, agrometeorological forecasts are valued as powerful and useful information for decision-making processes. The service can be implemented at low cost with effective technologies making it affordable and sustainable even in developing countries. Nonetheless, the service’s effectiveness depends on several aspects mainly related to the way information is communicated to the public.

Electrification development in rural areas is essential in order to meet electricity needs at bearable cost, for rural areas population development. This work presents optimization of hybrid electric power plant composed of solar photovoltaic and biogas generators, without electrical energy storage, for low-cost electrification of rural and peri-urban areas, at four sites in Sahel region of Burkina Faso. Simulation results give electricity kilowatt-hour cost about 0.0616 dollar at Gorom-Gorom site, 0.0611 dollar at Dori site, 0.0616 dollar at Djibo site and 0.0616 dollar at Sebba site. Compared to kilowatt-hour cost charged by the national electricity distribution company, who is from 0.1345 dollar, produced electricity cost at these sites is very competitive and accessible for this region population. Use of biogas in addition to solar as an energy source for electrical hybrid power plant has made it possible to reduce significantly polluting and greenhouse gas emissions.

The Impact

Wind power plants are an increasingly common source of electricity located in rural areas. As a result of the high variability of wind power, and thus the generated power, these sources should be classified as unstable sources. In this paper, the authors attempted to determine the impact of wind turbine operation on the parameters of electricity supplied to farms located near the source. As a result of the conducted field tests, variability courses of the basic parameters describing the supply voltage were obtained. The influence of power plant variability on the values of voltage, frequency, and voltage distortion factor was determined. To estimate the capacity of the transmission lines, the reactive power produced in the power plant and its effect on the value of the power factor were determined. The conducted research and analysis showed that the wind power plant significantly influences voltage fluctuations in its immediate vicinity (the maximum value registered was close to 2%, while the value required by law was 2.5%). Although all the recorded values are within limits specified by the current regulations (e.g., the THD value is four times lower than the required value), wind turbines may cause incorrect operation of loads connected nearby. This applies mainly to cases where consumers sensitive to voltage fluctuations are installed in the direct vicinity of the power plant.

Aims: The aim of the Green Communication Infrastructure ‎‎(GCI) project is to understand the idea of a self ‎‎"sustainably" controlled correspondence foundation ‎fitting for smart city application fields. ‎ Background: This paper shows the endeavors to understand the idea of a ‎self "sustainably" energized communication foundation ‎fitting for smart city application fields. The recommended ‎Green Communication Infrastructure (CGI) comprises ‎different kinds of remote settled (or even versatile) hubs ‎performing diverse activities as per the application ‎requests. An imperative class of these hubs is the Wireless ‎Solar Router (WSR). Objective: The work in this venture was begun in 2009 with the aim ‎of demonstrating the essential advances that must be taken to ‎accomplish such framework and to proclaim the value of ‎embracing natural vitality assets in building mission ‎basic frameworks. Alternate destinations of this venture ‎are introducing a sensibly cost, solid, verified, and simple ‎to introduce correspondence foundation.‎ Method: The arrangement to actualize the GCI was accomplished ‎subsequent to passing two structure levels: device level and ‎system level. Result: The suggested system is highly applicable and serves a wide ‎range of smart city application fields and hence many ‎people and organizations can utilize this system. ‎ Conclusion: The presence of a reliable, secured, low cost, easy to install ‎and self-powered communication infrastructure is ‎mandatory in our nowadays. The communities in ‎developing countries or in rural areas need such a system ‎highly in order to communicate with other people in the ‎world which will affect positively their social and ‎economic situation.

Congo Brazzaville

Housing as a place where household members spend about half (12 hours) of their daily time, including six to eight hours in sleep, is one of the essential conditions in the fight against poverty and precariousness.  The current Congolese urban environment is facing serious problems: small plots of land, lack of suitable housing in relation to the size and composition of households, overcrowding, and water and electricity supplies. This situation is becoming critical with the appearance of deviant behavior among children aged between 10 and 30. The government and its development partners have demonstrated their powerlessness face to this situation, leaving thousands of children on the streets without education or family warmth to form real criminal gangs. These street children have created the phenomena of "kuluna" and "black babies". It has been shown that these one act in this way for their survival, claiming their rights. In this study, we find innovative proposals to provide households sheltering adulterine and adoptive children with low-cost social housing, in order to restore the image of the head of the household and provide the children with a pleasant space for their physical, economic, cultural and spiritual development. This will undoubtedly help to find solutions to the problems facing children and indeed Congolese society as a whole today. The study revealed that if the government does not take practical measures in response to the phenomena created by wayward children, especially "black babies" and "kuluna", there will be a massive adherence of other children, especially the adulterine and adoptive ones. There will be a risk of the phenomena will to be exported to rural areas. The study recommends a "State - Household" partnership in the manufacture of new types of urban housing for households housing children likely to integrate or create gangs, jeopardizing social order and public security.

Utilization Of Wastes

Various ecological waste treatment and utilization systems (EWTUS) available in urban and rural areas in China are described, among which are land treatment and utilization systems (LTUS), eco-pond systems mainly consisting of macrohydrophytes-growing ponds, fish ponds and duck/geese ponds, and comprehensive circulation eco–systems for the treatment and utilization of wastes in rural areas, such as semi–closed eco–system in fish ponds, “rice–fish” and “rice–azolla–fish” symbiotic systems, recycling eco–systems with methane-generating digesters as central link, and comprehensive recycling eco–systems with digesters and eco–ponds as central link. In the various EWTUS, the sewage and wastewaters and other wastes are utilized and converted into various forms of recoverable resources and/or energy, while they are being purified to good quality effluents, meeting their respective discharge standards, and hence acceptable to receiving waters.
