The invasion of Cattail (Typha species) in Hadejia-Nguru Wetlands area, an Appraisal towards Exploring Various Management Techniques and Utilizing its Economic Benefits in The Area

Abstract

The Hadejia-Nguru wetland is an important wetland in the Sahelian region of Northern Nigeria. The wetland is very important to the regional economy by providing fertile alluvial soil for flood recession farming and dry season irrigation farming of vegetables and cereals (rice and wheat). It provides fish resources, fuelwood and other non-timber forest products. In recent years the area is facing a lot of problems and challenges among which are construction of dam at the upstream which distracts the normal flow of water to the downstream, population pressure causing conflicts between herders and farmers. The most serious problem is the proliferation of Typha spp an invasive species which blocks water ways and impedes farming and fishing activities, causing siltation and harbouring pests of grain crops (Red billed quelea), and vectors of malaria (Mosquitoes). The paper highlighted some management options for the Typha including, physical, mechanical, biological and chemical control as plan A. The Paper highlighted the various economic uses of the plant as option B for management including using it for biomass production, bio -coal production, harnessing the medicinal uses of the various plant parts, as a phytoremediation agent, using it as a source of food and incorporating it in the mixture of animal feeds among others.
