Preparations for the Rio+20 United Nations conference on sustainable development have begun, but the first round of preparatory meetings did not address important issues such as sustainable resource use, production and consumption.

Pollination of insect pollinated crops has been found to be correlated to pollinator abundance and diversity. Since organic farming has the potential to mitigate negative effects of agricultural intensification on biodiversity, it may also benefit crop pollination, but direct evidence of this is scant. We evaluated the effect of organic farming on pollination of strawberry plants focusing on if pollination success was higher on organic farms compared to conventional farms, and if there was a time lag from conversion to organic farming until an effect was manifested.

Wetlands play a big role as the important recreational destinations which contribute to the increase in tourism industry. This paper evaluates the recreational value of Lake Victoria in Musoma Municipality. Primary data were gathered by administering the questionnaire to a sample of 120 recreationists. The socio-economic data were analysed using Statistical Package for Social Sciences. Quantification of wetland benefits was done by using Microsoft Excel. The travel cost method was mainly used to determine the recreational value of the Lake Victoria.

Wetlands are among the most productive and economically valuable ecosystems in the world. However, because of human activities, over half of the wetland ecosystems existing in North America, Europe, Australia, and China in the early 20th century have been lost. Ecological restoration to recover critical ecosystem services has been widely attempted, but the degree of actual recovery of ecosystem functioning and structure from these efforts remains uncertain.
