The methodical fight against the water hyacinth or Eichhornia crassipes (Mart.) Solms Laub., prolific and invasive aquatic Pontederiaceae began in Burkina Faso in the years 97/98. Following the invasion of the plant in Burkina and following a better understanding of the phenomenon, an integrated control strategy was adopted in 1997, combining physical, chemical and biological control. After a few years of work combining the three methods, the results obtained in the field present very interesting aspects, but still reveal new constraints. During the year 2003, the integrated control method had allowed a total eradication of the biomass of the plant at the level of dam n°2.
The rainy season of 2004 saw a massive germination
of seeds produced in previous years and uae telegram data requires further research to determine the reasons. It was necessary to develop intense activity with the three recommended methods to keep the level of proliferation of the plant under control.KEYWORDS: Water hyacinth, integrated control, climate aaptation, Burkina Faso.
Water is essentially this non-substitutable natural resource, essential to life, and necessary for the various development sectors, hence the popular adage “water is life”, which reflects the full force of the multidimensional symbolism that water carries, particularly in a country in the Sahelian zone like Burkina Faso (PNE, 2015). The massive inputs of nutrients linked to the multiple human activities carried out v why does your company need a blog? around dam No. 2, constitute a pressure in the sense that they deteriorate the structures and pollute the water (Pelmont, 2005). According to J. Rutabagaya, (2017), in the rainy season the hyacinth covers almost the entirety of the Ouagadougou dam No. 2. Freshwater hyacinth grows on surface water and has quantitative v line data and qualitative impacts on water (J. Rutabagaya, 2017). Indeed, the spectacle of water hyacinth on dams is becoming more and more worrying. According to H. Karambiri (1998), it promotes flooding, sedimentation and the drying up of dams. This is why this study aims to analyze the contribution of communication in the fight against the hyacinth plant in dam No. 2 of Ouagadougou.
Geographical framework
Ouagadougou is the largest urban commune in Burkina Faso and the capital of the Kadiogo province. The commune of Ouagadougou is located in the heart of the said province between 12°15′ and 12°30′ north latitude and 1°24′ and 1°40′ west longitude, itself located in the center of Burkina Faso. It benefits from the influence of the North Sudanese climate due to its latitudinal location. This urban commune has, according to the new division, 12 districts, 55 sectors (INSD, 2022). The average annual rainfall is 755 mm (Gueye, 2004). It varies from more than 1,000 mm for the Comoé basin to around 600 mm for the Niger basin.
The methodology is based on the collection of qualitative and quantitative data. The literature review, the collection of primary and secondary data, the processing
and analysis of the information collected. Field work through interviews with users of the Ouagadougou dam No. 2 and finally field observations. The tools used are the interview guides which allowed the collection of qualitative information in the field, from the
technical services of the environment, from INERA of ONEA, and also from the press as a whole. The archives of RTB Burkina on a documentary on aquatic plants which took a large contribution from key players in
the field were used. A dictaphone was used to record the various interviews. The processing of this different information mobilized the QGIS
3.32 software, for the processing of geographic and spatial information for the production of maps, and the Word software for writing the article.
