About the Cover

Wetlands are among the most important and productive ecosystems in the world. In addition to being rich in biodiversity, they are known to play a vital role in food production, water quality treatment and sustaining rural livelihoods. However, over the years, changes have been observed in wetland surface area. The absence of an effective monitoring system/ tool in Zimbabwe means that these changes have neither been quantified nor analysed. In addition, there is no comprehensive inventory on wetlands. Thus the study makes use of geographic information systems and remote sensing tools to establish and quantify the spatio-temporal changes in wetland area that have occurred over the period from 1984 to 2014 in the Masvingo district of Zimbabwe. Landsat satellite images for the years 1984, 1986, 1995, 2006 and 2014 together with climatic data for Masvingo district were used in the study. Multispectral index, modified normalized difference water index was used to separate wetlands from other features and area that they occupy was then dternined using the histogram function in ILWIS GIS. Furthermore, the spearman’s rank-order correlation analysis was used to test for the nature of relationship between wetland areas with mean annual rainfall and mean maximum temperatures of the years understudy. The results show variability in wetland size over time but generally they show a declining trend.

Spatio-temporal variations of wetlands in Masvingo district of Zimbabwe and influences of climate change and variability

David Chikodzi, Linda Yeukai Mapfaka

Wetlands are among the most important and productive ecosystems in the world. In addition to being rich in biodiversity, they are known to play a vital role in food production, water quality treatment and sustaining rural livelihoods. However, over the years, changes have been observed in wetland surface area.

Climate Change & Water Resources

GIS based approach for the identification of artificial recharge sites in Annavasal Block, Pudhukkottai district, Tamilnadu

Rajesh J, Lakshumanan C

The selection of sites for artificial recharge is a very important task for recharge studies in the over exploited hard rock terrain. Occurrence and movement of groundwater in the hard-rock terrain are controlled by secondary porosities developed through weathering and fracturing

Climate Change & Pollution

Non-point source pollution in China, policies and best management practices: Lessons for Uganda

Natamba Leo, Zhang Weihua, Shiqiang Wei, Jinshong Zhang, Zhao Xiulin

Non-Point Source Pollution (NPSP) is a serious environmental threat for water ecosystems in China. It is created primarily by overuse of agrochemicals. Uganda, which is still far behind in developing its agricultural, industrial and mining sectors, is facing the same problem.
