Dynamic changes of land use and climate, as well biological invasions, are the result and at the same time the driving forces of a global change. They can prevent the sustainable use of natural resources and also reduce the stability of ecosystems and their biodiversity. Grasslands – one of the most important reserves of land for agricultural production and one of the most threatened biomes worldwide – are particularly affected.
For that reason, the transdisciplinary research project RuralFutures focuses on land-use changes in native South American grasslands, with a particular focus on Uruguay. While less than 1% of Uruguayan national territory enjoys conservation status, 95% is used for agriculture and forestry. In addition to the agro-industrial cultivation of soybeans for the globalised market, there has also been a rapid increase in afforested land. The area used for forestry is now 30 times bigger than it was 25 years ago. Mainly non-native species (i.e. eucalyptus, pinus) are being used. Although the ecological effects of these afforestation practices on ecosystems is the topic of much debate, there are few scientific studies available.
Objectives and methodology
The aim of the Rural Futures project is to demonstrate the complex environmental impacts on different land-use types and develop multifunctional, biodiverse and sustainable productive land-use concepts. RuralFutures works together with German and Uruguayan research institutes, government and non-governmental organisations, as well with national and transnational forestry and agriculture companies.
With 30 long-term monitoring stations along the climate gradient from the northwest to the southeast of Uruguay, we establish a complex evaluation system based conceptual framework of “Multifunctional and Sustainable Productive Landscapes” (see Wiggering et al. 2003, Holmes 2006, Taylor & Johnston 2009). With this evaluation system, we can collect reliable data on the ecological mechanisms and consequences of landscape change and define, together with local stakeholders, strategies for a multifunctional, sustainable, productive and biodiversity-friendly land use.
The RuralFutures long-term monitoring tasks will be handed over to students of local rural schools during the course of the project and integrated into their educational curriculum. In this way, we not only ensure long-term data collection and its transfer to the database, but also provide for new forms of scientific practice in schools. In this way, the RuralFutures project lays the foundations for critical, emancipatory environmental education for citizens and future scientists.
RuralFutures is funded by the German Federal Ministry for Education and Research (BMBF) and runs from 2014 to 2024 with funding of 2.6 million euro.
