The present study was carried out within the framework of knowing the evolution of the culture of voluble bean in the grouping of Miti. This culture is a leguminous plant which is consumed much by the inhabitants of the countries of the large lakes, where a person consumes per annum a quantity is equivalent to 50kg. However very significant for the inhabitants of the poor countries because its proteins measure with compasses those of origin with difficulty animal shows by the latter. Separately the voluble bean, there exists also the dwarf bean, but since the varieties of voluble bean were introduced, we saw all the agricultural producers embracing these last after they noted his production higher compared to dwarf bean. For testified acceptance to this culture, we saw all the farmers adopting sowings on line according to whether the popularizes theirs recommended, tans disc for the other cultures the majority sows their cultures in bulk, in spite of the councils received by some organizers. With this adoption, one could find almost everywhere this culture in all the fields and that for all the crop years. Curiously, after a time, we attended a regression, so that the culture is quasi non-existent in the medium. After study, we realized that most of the evaluated owners with 85% gave up the culture following the lack of the tutors and only one small number gave up for other reasons.

The grouping of Bugorhe is one of 14 groupings which account cheffery of Kabare, in the east of the Democratic Republic of Congo. Following the war of 1994 which led to the genocide in Rwanda, Hutu were refugee in Bugorhe by setting up there their camps thanks to then undoubtedly High commissionership for Refugees (HCR). About the year 1997, it was it tower of the RDC with a war known as of release which used the soldier’s Tutsi in order to reverse the capacity of Mobutu. With their arrived and their passage, all the camps of the Hutu refugees were destroyed and those last those which were likely to escape are directed in majority towards the National park of Kahuzi- Biega, a park located at the western part of the grouping of Bugorhe. With their arrived in the forest, unfortunately, the latter did not delay to leave the forest by causing acts of vandalisms to their hosts of yesterday who have nourishes them, sheltered them while killing, by raping the girls in the presence of their parents, their brothers, the moms in the presence of their husbands and in front of all the children, the fields cultivated by Congolese in end being collected by these same attackers, the peasants victims of these acts could not support and were obliged to move away in order to seek a place of takes refuge. Here is how the grouping of Bugorhe will be of a blow over-populated bus being crossed by the road Bukavu- Goma, but also sheltering the National Airport of Kavumu/Bukavu; the part being on both sides road is so much is made safe little and Being it much importance attaches to it. This being, the entity received a great number of moved interns, with this situation, waste multiplied as well as an anarchistic construction. After observation curiosity pushed us to make this study in order to account to us for the quantities of waste which produce the households but also the mechanisms of management of the latter in order to cleanse the medium. After study we noted that more than 60% of household more than one kg per week however produces the 100% of our surveyed confirmed that there is no public dustbin in this medium, that enables us to make a confirmation which it is possible to find by-here and by-there waste in small pieces where the peasants and even and especially at public places live. The sensitizing of the population on the management of waste as well as the adoption of a public dustbin as of other strategies would be a response to healthiness in grouping of Bugorhe.

The phenomenon of the famine is a problem that touches the big part of the population of the Democratic Republic of Congo in general and the one of the South-Kivu in particular. The agricultural production being least following multiple reasons as the excessive exploitation of soil without thinking about restoring him elements exported by cultures, the no respect of the cultural techniques succession, the disruption of seasons and other climatic risks; these dive the peasants agriculturist in a misery that makes that of time some have tendency to yet abandon the agricultural sector one of lever of development and survival in farming middle of the R D Congo and the source of the food substances. This being, we led this survey in view to demonstrate comparison that can exist as for the influence of the chemical manure (N P K) and the organic manure (manure of farm) on the dwarf bean so that the producer makes a discriminating choice between the two according to his financial means as well as his faculties to use one or the other. To the term of this experimentation, the manure of farm proved to be more important than the N P K and parcels no fertilized for nearly all observed parameters; bigger biomass, good harvest indication, weight of 100 seeds most elevated... The N P K stood in second position during the experimentation.

A survey has been conducted on the impact of wastes produced in the great establishments of Irhambi-Katana grouping, territory of Kabare, East of the Democratic Republic of the Congo. This study aimed to identify the impact of wastes produced by the great establishments of Irhambi-Katana grouping on human, the surrounding population and the environment. For reaching this objective, we used the method of collection of data by a questionnaire of inquiry and an interview in the great establishments of our study medium. After this inquiry and the analysis of the data collected, we accepted that the wastes in the great establishments of Irhambi-Katana grouping are bad stored according to the results found from our inquiries, the bad storage of the wastes in the great institutions of the Irhambi-Katana grouping sweeps along diseases and the nature pollution (atmospheric, of the water and of the soil) and the sensitization by an environmentalist agent and the creation of dump for wastes are the means for fighting against the consequences of these lasts on the environment and the human health. Thus, we recommended to the government to command respect the law on the wastes management and to the great establishments of Irhambi-Katana grouping to evacuate the wastes that they produce far from themselves for safeguarding the environment, the human and the surrounding population.
