Waitz was born in Vienna, Austria. After finishing school and traveling the world, he started a farm with his wife in the Leibnitz district in the very south of Styria in 1994. The primary sector of their farm is the mixed forest—a planter forest—based on the theory of near-natural forest management. The second focus of their farm is ecological beekeeping; it has about 70 colonies of the Carniolan honey bee. The third sector on the farm is the animal husbandry: Carniolan stone sheep and Border Collies. The Border Collies are trained as herding dogs. Waitz is also involved in a tiny lumber mill in Slovenia.
Political career
According to Waitz, the Greens are "the only serious political force interested in maintaining small-structured agriculture with all its positive effects on the environment and food quality and which is committed to small and organic farmers". Since he started with the Greens, Waitz has held and still holds a variety of positions: treasurer at the Green Education Workshop Styria, member of the Styrian provincial board, and member of the extended federal board. For more than ten years he has been involved in the green organization Grüne Bäuerinnen und Bauern, and since autumn 2017 he has served as chairman of the GBB Styria and the GBB Austria. Until 2016 he was also the first and only Green Chamber Councilor to sit in the provincial chamber for agriculture and forestry in Styria. In February 2017 Waitz applied for the position of board member of the European Green Party, and was elected in March 2017 at the 2017 Global Greens & European Greens Congress in Liverpool as the only Austrian board member of the European Green Party. In this position he is responsible, among other things, for the cooperation with Green Parties in the Czech Republic, Slovenia, Poland, Hungary and Albania and supports and accompanies the development of possible Green Parties in Croatia, North Macedonia, Montenegro, and Serbia. On 10 November 2017, Waitz took over Ulrike Lunacek's mandate in the European Parliament where he was, among other things, a member of the Committee on Agriculture and Rural Development and involved in negotiations on the new funding guidelines 2021-2027 for the Common Agricultural Policy. He politically focuses on agriculture and the wide range of issues it covers, from food quality, food safety, and animal welfare to combating climate change. Waitz is committed to a common, eco-social economic policy of the EU and uniform social standards within Europe. However, he would also like to see other areas delegated back to the member states, in which the states can make decisions closer to the citizens, and cites as an example what he sees as unnecessary over-regulation for direct marketing by farmers. Waitz attracts a lot of attention with his actionism. For example, in 2016 he laid down tree trunks infested by bark beetles in front of the country house in Graz's Herrengasse street, and in January 2018 he cooperated with the Styrian police to stop illegal animal transporters. Besides environmental and agricultural policy, he is also involved in peace policy-making; in particular he is working for a Europe-wide ban on nuclear weapons. The joint protest action at Tom received particular attention from the members of parliamentTilly Metz from Luxembourg, Molly Scott Cato from Great Britain, and Michèle Rivasi, who supported the unfurling of a banner on the runway of the military airport Kleine Brogel in Belgium, which drew attention to the permanent presence of US nuclear warheads in the middle of Europe. After the 2019 European Parliament election Waitz was unable to take up his mandate directly but had to wait until the British MEPs left in February 2020 due to Brexit. In addition to the Committee on Agriculture and Petitions as deputy, Waitz is a member of Parliament's Foreign Affairs and Security Policy Committee and a delegate to the Association Committees on Albania, Montenegro, Bosnia, and Herzegovina and Kosovo as deputy.
