Climate Change Impacts on Water and Agriculture Sectors in Southern Africa: Threats and Opportunities for Sustainable Development (2020, background): “Empirical evidence indicates that agriculture food systems and communities vulnerable to extreme weather changes are expected to be more vulnerable in future climate change shocks [8,15,19,43].”
The role of knowledge and power in climate change adaptation governance: a systematic literature review (2013, background): “2 (Challinor et al. 2007) National Theoretical Organized power (institutions) and organized knowledge (climate models, crop yield models) are diagnosed and show an un-preferable picture in combination with a changing climate.”
Biological Diversity in Agriculture and Global Change (2010, background): “Many inhabitants of tropical and subtropical regions of developing countries tend to be the most exposed and vulnerable to the combined social-environmental dynamics of global change (4, 5, 100, 102, 121, 123, 124, 126, 127).”
Climate change impacts on crop productivity in Africa and South Asia (2012, background): “Others cite the lack of site specific parametrization of the crop management options and cultivars (Müller et al 2011), and the risk of model overtuning (Challinor et al 2007).”
Rainfall intensity and groundwater recharge: empirical evidence from the Upper Nile Basin (2009, background): “The former will exacerbate intra-annual freshwater shortages and the risk of flooding whereas the latter threatens food security through reduced crop yields [4].”
A spatially explicit assessment of current and future hotspots of hunger in Sub-Saharan Africa in the context of global change (2008, background): “Direct comparison of the impact of climate change on crop production between this study and other studies is difficult because they encompass a range of different periods, regions and crops, and the uncertainty ranges can come from several sources such as spatial variability inyield, uncertainty in ”
Adaptation to climate change through the choice of cropping system and sowing date in sub-Saharan Africa (2013, positive): “The degree of climate change impacts on agricultural production differs between crops (Challinor et al., 2007; Liu et al., 2008; Schlenker and Lobell, 2010; Thornton et al., 2011) and agricultural systems (Thornton et al., 2010).”
Making seed systems more resilient to stress (2013, background): “Existing literature on key components for resilient seed systems is limited, focusing mainly on supply channels in formal or farmer systems (e.g. Bellon et al., 2011; Challinor et al., 2007).”
Mapping South African farming sector vulnerability to climate change and variability: A subnational assessment (2009, background): “It is impossible to directly predict crop yields under potential future climates on a decadal timescale (Challinor et al. 2007).”
Climate change and the growth of the livestock sector in developing countries (2010, background): “Overall, crop yields in Africa may fall by 10–30% to 2050 and beyond, because of warming and shifts in rainfall amounts and patterns ( Challinor et al. 2007 ), but there are places where yield losses may be much more severe, as well as areas (particularly in the tropical highlands) where crop yields”
Linking agricultural adaptation strategies, food security and vulnerability: evidence from West Africa (2016, positive): “…are stronger for market-oriented households, which supports the ﬁndings of other authors that proximity to markets, information sources and rural advisory services are important to trigger and facilitate successful adaptation at the household level (Challinor et al. 2007; Silvestri et al. 2012).”
A food systems approach to researching food security and its interactions with global environmental change (2011, background): “Methods for estimating regional production–and especially how it will change in future–are still relatively weak, with analyses mainly relying on statistical approaches or extrapolation from mechanistic point models, although mechanistic modelling approaches also exist (e.g. Parry et al. 2005; Chall”
Crops and climate change: progress, trends, and challenges in simulating impacts and informing adaptation. (2009, methodology): “They are faced with a difficult task, since each of the individual studies tends to use only one method for one region, and for a limited number of crops (see above and Challinor et al., 2007).”
