In the literature there is a clash of views and opinions concerning water projects and their effects on environment and man. That inducted myself to penetrate these changes, which appears in the zone of influence of water projects. So the subject of this study is one of the most controversial side effects of water projects - spread of water born diseases. Both sides (proponents and opponents of water construction) most often make us of their own statistical data, which are frequently divergent and their mention their own examples. In such circumstances it start to be very interesting for me to investigate influence of water projects built in Africa and Asia on spread of tropical diseases like: schistosomiasis, malaria, filariasis with onchocerciasis. All of this sickness are the most widespread and danger in tropi cal zone. Differentiation’s of environmental and social conditions affect possibilities of water-born prevalence. There are several factors that might modify process and tempo of sick rate. So in order to take into consideration most of this modifying elements I choose to investigate such factors like: - type of hot climate, where water projects are localized; - environmental attributes like, in example chemistry of water, temperature of air and water, etc., which may affects existence of vector of diseases; - hygienic habits and cultural practices (particularly division of labor); - migration In this study are annalist more then 30 water projects in many African and Asian countries (most of them African).

W pracy omówiono zmiany w zachorowalności na choroby pasożytnicze wśród mieszkańcow międzyzwrotnikowych regionow Afryki i Azji. Analizie został poddany wpływ jaki na rozprzestrzenianie się bilharcjozy, malarii i filarioz (w tym ślepoty rzecznej) mogą mieć realizowane na tych terenach inwestycje wodne, takie jak budowa zapór, kanałów nawadniających, wypełnianie zbiorników zaporowych, a w konsekwencji powiększające się obszary rolnictwa nawadnianego.
