Combining satellite data and models to assess vulnerability to climate change and its impact on food security in Morocco

Combining satellite data and models to assess vulnerability to climate change and its impact on food security in Morocco

This journal article analyses satellite and socioeconomic data to explore the relationship between food and wood demand and supply, expressed in terms of net primary production (NPP), in Morocco. A vulnerability index is defined as the ratio of demand to supply as influenced by population, affluence, technology and climate indicators. The researchers found that the food NPP demand increased by 34.5 per cent, whereas the wood consumption NPP demand decreased by 19.3 per cent between 1995 and 2007. The annual NPP required to support the population’s food and wood appropriation was 29.73 million tons of carbon (MTC) in 2007, while the landscape NPP production for the same year was 60.24 MTC; indicating that the population appropriates about 50 per cent of the total NPP resources. Both scenarios show increases in demand and decreases in supply. The paper argues that an already high vulnerability for food and wood products is likely to be exacerbated with climate changes and population increase.
