Optimierung unter Unsicherheit mit Hilfe stochastischer Simulation und Genetischer Algorithmen - dargestellt anhand der Optimierung des Produktionsprogramms eines Brandenburger Marktfruchtbetriebes -

Mußhoff, Oliver; Hirschauer, Norbert - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 53 (2004) 7, pp. 264-279

Optimization has been recognized as a powerful tool in teaching and research for a long time. In spite of its well known problem solving capacity, some methodological obstacles have persisted over the years. The main problem is that stochastic variables and their correlations cannot be...

The Risk Reduction Potential of Weather Derivatives in Crop Production: Simple Indices versus Mixed Indices

Pelka, Niels; Mußhoff, Oliver - In: German Journal of Agricultural Economics (GJAE) 62 (2013) 4, pp. 231-243

Weather derivatives are impaired with a basis risk that reduces the risk reduction potential and possibly hinders the … risk is the use of mixed indices composed of several weather variables. The present study compares the risk …-reduction potential of a temperature index-based and a precipitation index-based weather derivative to a derivative based on a mixed index …

Social rate of return to plant breeding research in Germany

von Witzke, Harald; Jechlitschka, Kurt; Kirschke, Dieter; … - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 53 (2004) 5, pp. 206-210

This article focuses on the social rate of return to plant breeding investment in Germany between 1980-2000. Starting point of the analysis is the development of total factor productivity which is decomposed into the effects of factor input and research investment. Information on investment in...

Post-Soviet changes in cropping practices in the irrigated drylands of the Aral Sea basin

Rufin, Philippe; Peña-Guerrero, Mayra Daniela; … - In: Environmental Research Letters 17 (2022) 9

Water withdrawals for irrigated crop production constitute the largest source of freshwater consumption on Earth. Monitoring the dynamics of irrigated crop cultivation is crucial for tracking crop water consumption, particularly in water-scarce areas. We analyzed changes in water-dependent crop...

Field-level land-use data reveal heterogeneous crop sequences with distinct regional differences in Germany

Jänicke, Clemens; Goddard, Adam; Stein, Susanne; … - In: European Journal of Agronomy 141 (2022), pp. 1-12

Crop cultivation intensifies globally, which can jeopardize biodiversity and the resilience of cropping systems. We investigate changes in crop rotations as one intensification metric for half of the croplands in Germany with annual field-level land-use data from 2005 to 2018. We proxy crop...

Nourishing the farms, nourishing the plates: Association of climate‐smart agricultural practices with household dietary diversity and food security in smallholders

Santalucia, Simone; Sibhatu, Kibrom T. - In: Agribusiness 40 (2023) 2, pp. 513-533

Climate-smart agricultural (CSA) practices are increasingly being promoted as nature-based solutions to improve the livelihoods of smallholder farm households amid a sharp increase in climate-change anomalies. However, the extent to which CSA practices contribute to smallholder food security and...

South African food security and climate change: Agriculture futures

Dube, Sikhalazo; Scholes, Robert J.; Nelson, Gerald C.; … - 2013

The projected changes in planted area, yield per area, net exports/imports and priced for five major agricultural crops in South Africa were simulated using the projections of four Global Circulation Models (GCMs) under three socio-economic scenarios. The GCM runs were those undertaken for the...
