“…Does household livestock production respond to access to markets and weather conditions? Despite several studies showing that crop production responds to weather conditions (e.g., Rosenzweig and Binswanger 1993;Dercon 1996;Jalan and Ravallion 2001;Howden et al 2007;Mitter et al 2015;Amare et al 2018;Jagnani et al 2018) 1 and access to markets (e.g., de Janvry et al 1991;Fafchamps 1992: Zeller et al 1998Van Dusen and Taylor 2005), there exists scant empirical evidence on whether and how households' livestock production decisions respond to varying weather risk and access to markets. Understanding these responses and adjustments in livestock production and marketing decisions is crucial for prioritizing livestock-related investments and designing risk mitigating strategies for those relying on livestock, e.g., livestock insurance programs.…”

Despite several studies showing the effect of access to markets and weather conditions on crop production, we know quite little on whether and how livestock production systems respond to variation in weather risk and access to markets. In this paper, we study whether and how livestock production responds to access to markets and varying weather risk. We also explore whether such responses vary across livelihood zones and livestock production systems. We study these research questions using information on the livestock production, ownership, and marketing decisions of households in Ethiopia. We find that households living close to markets are more likely to engage in market-oriented livestock production and use modern livestock inputs. We also find that households exposed to more unpredictable weather are less likely to engage in livestock production for markets. Rather, they are more likely to engage in livestock production for precautionary savings and insurance. Furthermore, greater rainfall uncertainty influences livestock portfolio allocation towards those types of livestock which can be easily liquidated, while also discouraging investment in modern livestock inputs. However, these responses and patterns vary across livelihood zones and production systems-most of these stylized responses and impacts are more pronounced in the arid and semi-arid lands of Ethiopia, where livestock herding remains a dominant source of livelihood. Those households relying only on livestock production seem more sensitive and responsive to weather risk and weather shocks. The heterogeneity in responses to and impacts of weather risk among farming systems and livelihoods highlights the need for more tailored livestock sector policies and interventions.

“…These results are in accordance with current research findings. For example, according to Mitter et al (2015) who applied a portfolio optimization model for Austria, crop production portfolios include higher shares of intensive crop management practices, increasing average crop yields by 2-15% and gross margins by 3-18% under changing climate. According to them solution might be the threefold increase in agri-environmental premiums which would reduce nitrogen inputs by 23-33%.…”

“…Farmers are expected to adapt to climate change-induced developments such as longer vegetation periods in the long term (past 2040) (Olesen et al 2011;Mitter et al 2015) and changed weed systems by using different plant varieties (climate change adaptation) (Table 5). Developing plant varieties in terms of their pathogen tolerance and their defense mechanisms below ground is a research topic that may also become more practically relevant in the future once research has advanced (Johnson et al 2016;Rasmann et al 2017) (Table 5).…”

Global trends in demand for biomass-based food, feed, energy, and fiber call for a sustainable intensification of agricultural production. From the perspective of sustaining soil functions, this implies the integration of soil productivity with the other soil functions and services, namely carbon sequestration, water purification and retention, and nutrient and matter cycling as well as biodiversity. Soil management is the key to this integration. The proper anticipation of future opportunities and challenges for sustainable soil management requires an analysis of drivers and trends affecting soil management. Here, we review drivers and trends of soil management and their relevance for soil functions taking Germany as an example of industrialized agricultural systems with low yield gaps. We analyzed socio-economic, biophysical and technological drivers and identified two types of future management changes: (1) Quantitative changes, i.e., more or less of the same input factors, such as fertilizers, as part of a moderate intensification. (2) Qualitative changes: There, we found the strongest signals for the following practices: higher precision and lightweight machines triggered by information and communication technology (ICT) and robotics; diversification of crop rotations, including the integration of lignocellulosic crops; inoculation with biota; and new crop varieties. Positive practices may be reinforced by a behavioral trend towards sustainable soil management, driven by increasing awareness, knowledge, and consumer demand. They offer opportunities for relieving mechanical pressures from weight and contact stress, chemical pressures from pesticides and fertilizers and promoting soil biodiversity without compromising the soil's production function. We also found threats, such as increased removal of organic residues and potentially harmful organisms. This foresight study is the first to delineate opportunities and challenges for sustainable soil management and intensification. It informs researchers who intend to improve the knowledge base for reinforcement of positive and mitigation of negative trends of soil management.
