Food security in a world of natural resource scarcity: the role of agricultural technologies

Posted by on 2021-12-23

The world’s population is expected to reach 9 billion by 2050. Climate change, population, and income growth will drive food demand in the coming decades. Baseline scenarios show food prices for maize, rice, and wheat would significantly increase between 2005 and 2050, and the number of people at risk of…

Forest futures: Linking global paths to local conditions

Posted by on 2021-12-23

The chapter establishes links between elements of long-term global scenarios and the prerequisite conditions of sustainable forest management (SFM), as discussed in Parts I and III. It uses a component from a new global scenario exercise: the shared socio-economic pathways (SSPs), which are narratives that cover a spectrum of climate…

Integrating livestock feeds and production systems into agricultural multi-market models: The example of IMPACT

Posted by on 2021-12-23

The various ways in which livestock production systems can be incorporated into economic, partial-equilibrium, multi-market models are presented, and the challenges outlined. A particular focus and illustrative case is livestock feed. Foremost among the challenges is the reconciliation of scientific understanding of livestock feed requirements and production characteristics with the…

Mapping the economic benefits to livestock keepers from intervening against bovine trypanosomosis in Eastern Africa

Posted by on 2021-12-23

Endemic animal diseases such as tsetse-transmitted trypanosomosis are a constant drain on the financial resources of African livestock keepers and on the productivity of their livestock. Knowing where the potential benefits of removing animal trypanosomosis are distributed geographically would provide crucial evidence for prioritising and targeting cost-effective interventions as well…

Climate change mitigation through livestock system transitions

Posted by on 2021-12-23

Livestock are responsible for 12% of anthropogenic greenhouse gas emissions. Sustainable intensification of livestock production systems might become a key climate mitigation technology. However, livestock production systems vary substantially, making the implementation of climate mitigation policies a formidable challenge. Here, we provide results from an economic model using a detailed…

African Livestock Futures: Realizing the potential of livestock for food security, poverty reduction and the environment in Sub-Saharan Africa Report

Posted by on 2021-12-23

The study builds on the IPCC’s Shared Socioeconomic Pathways (SSP) scenarios and examines three variants: a sustainable intensification scenario with high economic growth, high GDP growth, changing diets and a high degree of technological change (SSP1); a continuation of current trends (SSP2); and a degradation scenario with…
