| 1 | Water quality in forest and village ponds in Burkina Faso(western Africa)显示文摘Forest ecosystems help conserve the quality of water resources in aquatic habitats.The conservation of biological diversity in aquatic and terrestrial ecosystems remains a communal concern.Aquatic ecosystems and resources are vulnerable but can be preserved and protected by forests.In sub-Saharan regions of Africa,water from ecosystems such as ponds still play important role in the livelihood of local populations.Water from temporary ponds is used by local populations for multiple needs;however,in this part of the world,the population is increasing,thus increasing human needs and activities and land use in the region.Land-use changes lead to deforestation,land degradation and the decline in freshwater,affecting human health and well-being.Forest degradation leads to the decline in ecosystem goods and services,particularly those related to watersheds.This study conducted in eastern Burkina Faso aimed to assess water quality of temporary ponds in protected forest areas(reserves) and surrounding villages.It was conducted in 61 temporary ponds where physical,chemical and biological variables were measured,such as water surface area,depth,transparency,macrophyte cover,p H,dissolved O_2,conductivity,nutrient concentrations and algae biomass.The results showed that at p<5%,water surface area(p = 0.02),depth(p = 0.00),nutrient content(p = 0.00),and algae biomass(p = 0.04) were significantly higher outside reserves than inside reserves.In contrast,macrophyte cover(mean cover percentages 53 vs.44.5%) and water transparency(p = 0.02) were higher inside reserves.The variations in conductivity and p H were not significant.All trends showed the influences of human activities on water characteristics and the role forests and land cover had in preventing negative human impacts and disturbance of temporary ponds.Forests and land cover are important to water quality conservation and algae biomass regulation in temporary ponds.Protecting and managing forests is therefore an essential part of future strategies for limiting algal blooms and their negative consequences,maintaining water quality and providing clean water to citizens. | Bilass Zongo Frdric Zongo Aboubacar Toguyeni Joseph I.Boussim | 2017 | Journal of Forestry Research2017，28，5： | 0 |
