Investigating Water Crisis in Iran

Jaberizadeh, Homa January 2020 (has links)
Though some have the opportunity to access water conveniently, getting a small amount of water may be tough and exhausting for others. In this paper, I will discuss on the right to water, which is explicitly expressed by a UN resolution as a human right. Sever water crisis, or drought, has been far beyond a lack of precipitation, but a phenomenon, occurring through a set of human activities, and interferences. My initial aim is to find out how and in what ways some human activities in Iran, interfered environment in a way that affected precipitation level and led to water crisis. And the second, is to show how unethical these activities may be, as they have been simply avoidable. Therefore, the Iranian governmental organizations (like municipalities) are ethically responsible to provide the required water, since the right to water is called a basic human right by UN. These facts obliges them to hinder these activities to secure this basic need. On this way, I make use of Nussbaum's capability approach to show, depriving the citizens from one of their basic rights (the right to water), through influencing climatic order (in a way that decreases precipitation level or depletes water resources), is considered a moral issue, therefore, it is binding for the state to take measures responsively to stop and control it in the future.

Impacts des variations de la crue sur les communautés rurales du delta intérieur du bassin versant du fleuve Niger / Impacts of water high level variation on rural communities in the internal delta of Niger river bassin

Illou, Mahamadou 09 December 2010 (has links)
Cette étude intervient dans un contexte de baisse de crue dans le delta intérieur du bassin versant du fleuve Niger. Cette baisse de crue mise en évidence par les chercheurs, a été constatée par les populations. Les principales activités des populations du delta intérieur à savoir l’agriculture, l’élevage et la pêche font vivre des milliers de personnes particulièrement dépendantes de l’évolution de la crue. Lorsque la crue baisse, on assiste à des pertes de superficies irrigables, à des variations du niveau et du temps d’inondation des terres lesquelles agissent sur le calendrier cultural. Ces impacts concernent également divers niveaux dans les secteurs de la pêche et de l’élevage en raison des liens étroits qui existent entre l’inondation et ces activités. Les conséquences de la baisse de la crue sur l’agriculture se font particulièrement ressentir non seulement sur les rendements et les superficies inondables, mais aussi sur la productivité des terres. S’agissant de l’élevage, les impacts se traduisent par la réduction des aires pastorales et la diminution des troupeaux, mais surtout par des mutations sociales. Par ailleurs, dans le domaine de la pêche, s’opère la diminution progressive des captures et des espèces. Tous ces évènements agissent négativement sur la vie socio-économique des populations, avec une réduction significative des capacités endogènes de prises en charge des ménages. Aussi, les populations tentent-elles de s’adapter à leurs nouvelles conditions de vie, en apportant diverses réponses, dont entre autres, la reconversion à d’autres activités, l’exercice d’activités complémentaires, l’amélioration des pratiques culturales. Mais la stratégie la plus fréquente concerne la migration avec comme conséquence la déstructuration du tissu social, situation qui rend inefficace les mesures d’adaptation prises par les populations pour faire face à la baisse de la crue. Malgré les multiples efforts fournis par les populations, les ONG et l’Etat, beaucoup reste à faire. Les perspectives qui s’offrent au delta sont mitigées : d’une part la construction des barrages en amont et en aval du delta suscite des espoirs dans la perspective d’intensification des activités agricoles et donc l’amélioration des rendements et d’autre part la perte de superficies inondables liées à la régulation du fleuve prévue par le projet de construction de ces barrages. / The present study is carried out within a context of the low level of water in the interior delta Niger River. The water shortage is first noticed by eminent readers and observed by the local population itself. The main activities are agriculture, breeding and fishing which provide the needs of thousands of people in the area depend on the evolution of water. Once there is water shortage, we do observe the lost of cultural areas, variations in the level of water and that of inundation which influence the agricultural calendar. Definitely the phenomenon has implications on fishing and breeding giving the fact that there is a link between inundation and other activities. The consequences of the water shortage on agriculture are more visible on the outcome and the areas watered and more importantly on the fertile soil but also on the soils productivity. With regard to breeding, the impacts manifest themselves in the reduction of breeding areas, the herd and on social changes. On the other hand, in the fishing sector we do notice the decrease in fishing and the types of fishes. All these influence negatively on the socio economic life style of the local populations as well as significant decrease in its ability to sustain itself. Equally, the populations is getting use to a new life style by initiating several responses among which the revert to other activities, the practice of complementary activities, the improvement in agricultural practices. But, the most developed strategy is that of migration which immediate consequence is the destruction of social fabric, a situation that may yield to inefficient strategies initiated by the populations in order to challenge the decrease of water. In spite of efforts made by the populations, NGOs and public authorities, a lot needs to be done. The perspectives are not much : on one hand, the building of dams in the Delta creates hope in view of the intensification of agricultural activities and hence in improving the productivity, on the other hand, the lost of inundable areas linked to the above project.
