iCROPM 2020
Montpellier, 3.-5. February 2020

Crop modellers from around the world met at the iCROPM2020 conference to exchange on advances in crop modelling and identify challenges and new opportunities for future research. iCROPM2020 focused on recent improvements and crop simulation model applications that support agricultural production and food security under global change. Many crop types and cropping systems (arable, grasslands, including intercrops and mixed cropping systems) and climatic regions were considered, including high and low inputs systems with relevance for large agricultural enterprises to smallholder farmers.

From the TROPAGS team, Prof. Reimund Rötter, Dr. Gennady Bracho-Mujica and Dr. William Nelson took part. Abstracts of the papers and presentations that we were involved with are available here for download, and have been published in the Book of Abstracts on the pages 78/79, 181/182, 433/434 and 524/525.

4.11.2019 - PIK Press Release: Early warning: Physicists from Giessen, Potsdam and Tel Aviv forecast "El Niño" for 2020

The serious weather phenomenon "El Niño" could soon occur again in the Pacific region. Researchers at Justus Liebig University Giessen (JLU), the Potsdam Institute for Climate Impact Research (PIK) and Bar-Ilan University in Ramat Gan, Israel, find that there will probably be another "El Niño" by the end of 2020. The prediction models commonly used do not yet see any signs of this.

14.10.2019 - PIK Press Release: PIK and MCC provide detailed assessment of the climate package
The Potsdam Institute for Climate Impact Research (PIK) and the Berlin Climate Research Institute MCC (Mercator Research Institute on Global Commons and Climate Change) presented a detailed assessment of the so-called climate package. It states that the climate protection programme adopted by the federal government last week, which intends to limit greenhouse gas emissions, especially in the major problem areas of traffic and heat, is in all likelihood insufficient to achieve the 2030 climate goals.
Primarily, policymakers have to make four adjustments: First, they need to raise the level of ambition in pricing carbon dioxide emissions; second, they need to improve social equality; third, they need to further arrange the transfer to EU level and, fourth, implement an effective monitoring process.

The detailed assessment of the climate package can be downloaded here.

25.9.2019 - Press Release: Increased risk of simultaneous droughts in wheat-growing areas
Reimund Rötter involved in international study in Science Advances

Wheat_NewsIf global greenhouse gas emissions continue to rise unabated, the risk of extreme droughts simultaneously affecting central wheat-growing areas could increase three to fourfold by the end of the century. This is the conclusion of an international study involving the University of Göttingen. Even with a significant reduction in CO2 and other greenhouse gas emissions, the scientists estimate the risk will double.

18.3.2019 - South African local newspaper reports about SALLnet
Students and academics from the University of Göttingen in Germany visited the Levubu area in February to discuss a new research project, the South African Limpopo Landscapes Network, which will conduct research into the socio-economic and biological impacts of climate change in agricultural landscapes in Limpopo. At a well-attended meeting of the Macadamia Study Group on 21 February, Profs Reimund Roetter (Department of Crop Sciences) and Jan-Henning Feil (Department of Agricultural Economics and Rural Development) from the University of Göttingen outlined the project and enlisted the enthusiastic support of local macadamia farmers to conduct a farm survey in the region to better understand risks to the industry from climate change and other causes.

Plaas Guest House, Louis Trichardt, South Africa

During this half day meeting with macadamia farmers, stakeholders and scientists the results from the first phase of the project (LLL) were presented by Valerie Linden, Sina Weiner and Ingo Grass. Catrin Westphal (Department of Functional Agrobiodiversity) introduced the planned research activities for the second phase of the project (SALLnet). Both the results of the first phase and future research plans were intensively discussed among famers, scientists and stakeholders.

SALLnet will have its first annual meeting at Wits Rural Facility, South Africa, in September 2019
