According to a press release by UNV in October 2001, lawmakers in France, Germany, Spain and the UK passed pro-volunteer legislation in 2001, and new laws were proposed in Argentina, Colombia, Ecuador, Madagascar, Mozambique, Nepal, Senegal and Tanzania. Also for the year, UNV and the Independent Sector released "Measuring Volunteering: A Practical Toolkit," a survey guide to measure the economic contribution of volunteering. The press release says the toolkit was adapted for use in Botswana, China, Lao PDR, Kazakhstan and Mongolia, and that research on volunteering had begun in Cambodia, Madagascar, Namibia, Sri Lanka and Tanzania.[21]
