    Content: Global climatic change will most likely affect natural resources and human living conditions in semiarid regions. This volume presents disciplinary as well as integrative methods to assess these impacts considering the interactions between climate variability and change, water availability, land-use systems, and quality of life. Taking the semiarid northeastern area of Brazil as an example, a wide range of expertise and knowledge (from integrated water analyses to transregional migration) is necessary to understand the complex relationship between natural and socio-economic systems. Tools to integrate this knowledge and make it available for the strategic planning of sustainable development are described. This book is a summary of the main research results and the presentations given at the final conference of the WAVES Program on June 25-26 2001 in Fortaleza (Brazil). From the reviews: "This book focuses on results from a joint German-Brazilian program (Water Availability and Vulnerability of Ecosystems and Society, or WAVES) to assess the socioeconomic impacts that global change will have on northeast Brazil. This book, divided into eight parts, describes the many factors that should be included in developing scenarios for future planning purposes. The book provides useful information concerning the complex multidisciplinary task of developing scenarios that can aid decision makers in formulating plans for sustainable development in an area that is highly vulnerable to climate variability and change. For someone who is unfamiliar with the semiarid northeast Brazil region, the book provides considerable useful background information." (Vernon E. Kousky, BULLETIN OF THE AMERICAN METEORLOGICAL SOCIETY, December 2004)

    Simulating Root Growth as a Function of Soil Strength and Yield With a Field-Scale Crop Model Coupled With a 3D Architectural Root Model (2022)

    Content: Accurate prediction of root growth and related resource uptake is crucial to accurately simulate crop growth especially under unfavorable environmental conditions. We coupled a 1D field-scale crop-soil model running in the SIMPLACE modeling framework with the 3D architectural root model CRootbox on a daily time step and implemented a stress function to simulate root elongation as a function of soil bulk density and matric potential. The model was tested with field data collected during two growing seasons of spring barley and winter wheat on Haplic Luvisol. In that experiment, mechanical strip-wise subsoil loosening (30–60 cm) (DL treatment) was tested, and effects on root and shoot growth at the melioration strip as well as in a control treatment were evaluated. At most soil depths, strip-wise deep loosening significantly enhanced observed root length densities (RLDs) of both crops as compared to the control. However, the enhanced root growth had a beneficial effect on crop productivity only in the very dry season in 2018 for spring barley where the observed grain yield at the strip was 18% higher as compared to the control. To understand the underlying processes that led to these yield effects, we simulated spring barley and winter wheat root and shoot growth using the described field data and the model. For comparison, we simulated the scenarios with the simpler 1D conceptual root model. The coupled model showed the ability to simulate the main effects of strip-wise subsoil loosening on root and shoot growth. It was able to simulate the adaptive plasticity of roots to local soil conditions (more and thinner roots in case of dry and loose soil). Additional scenario runs with varying weather conditions were simulated to evaluate the impact of deep loosening on yield under different conditions. The scenarios revealed that higher spring barley yields in DL than in the control occurred in about 50% of the growing seasons. This effect was more pronounced for spring barley than for winter wheat. Different virtual root phenotypes were tested to assess the potential of the coupled model to simulate the effect of varying root traits under different conditions.

    Nutrient deficiency effects on root architecture and root-to-shoot ratio in arable crops (2023)

    Content: Plant root traits play a crucial role in resource acquisition and crop performance when soil nutrient availability is low. However, the respective trait responses are complex, particularly at the field scale, and poorly understood due to difficulties in root phenotyping monitoring, inaccurate sampling, and environmental conditions. Here, we conducted a systematic review and meta-analysis of 50 field studies to identify the effects of nitrogen (N), phosphorous (P), or potassium (K) deficiencies on the root systems of common crops. Root length and biomass were generally reduced, while root length per shoot biomass was enhanced under N and P deficiency. Root length decreased by 9% under N deficiency and by 14% under P deficiency, while root biomass was reduced by 7% in N-deficient and by 25% in P-deficient soils. Root length per shoot biomass increased by 33% in N deficient and 51% in P deficient soils. The root-to-shoot ratio was often enhanced (44%) under N-poor conditions, but no consistent response of the root-to-shoot ratio to P-deficiency was found. Only a few K-deficiency studies suited our approach and, in those cases, no differences in morphological traits were reported. We encountered the following drawbacks when performing this analysis: limited number of root traits investigated at field scale, differences in the timing and severity of nutrient deficiencies, missing data (e.g., soil nutrient status and time of stress), and the impact of other conditions in the field. Nevertheless, our analysis indicates that, in general, nutrient deficiencies increased the root-length-to-shoot-biomass ratios of crops, with impacts decreasing in the order deficient P 〉 deficient N 〉 deficient K. Our review resolved inconsistencies that were often found in the individual field experiments, and led to a better understanding of the physiological mechanisms underlying root plasticity in fields with low nutrient availability.
