Organic food systems meeting the needs of Southern Africa.

Book cover for Organic food systems meeting the needs of Southern Africa.

Description

This book reports on long-term comparative organic farming systems' research trials carried out over the last 5 years in the Southern Cape of South Africa, as well as research into the successes and failures of the organic sector and the technical tools required for sustainable development in South Africa, Zambia, Uganda and Tanzania. It includes 24 chapters organized into 4 parts. Part 1 (Chapter...

The likely impact of the 2015-2018 drought in South Africa: lessons from the 2008 food price crisis and future implications.

Although still controversial, several reviews of research show that organic foods are more nutritious and contain fewer poisons than conventional foods. Poor food choices lead to low dietary diversity, and refined foods have many nutrients removed; low nutrient density and high sugars, salts and hydrogenated fats lead to the consumption of 'empty calories', and thence to obesity. Access to urban food gardens and to agriculture in rural areas increases dietary diversity scores, but weather shocks lead to price shocks which often decrease availability of food. Climate change will increase the severity of fires, and has contributed (through the 2015-2018 drought) to food prices increasing by 16.1% over this period. Even where child grants and pensions cushioned these shocks, stunting has not decreased. Dietary diversity is poor, often leading to the consumption of empty calories, but urban vegetable gardens can improve dietary diversity scores, as well as community solidarity, though impacts on local ecology only occur when gardens are linked to river health and school activism. A 1% increase in food prices leads to a 2.5% decrease in the number of food items purchased. Although child grants have decreased the experience of hunger, in particular child hunger (in 2011, hunger was less than half of 2001 levels), the percentage of stunted children has not changed much over the past 20 years, with about 27% of children under 5 stunted (10% severely stunted). Food in security is largely related to poverty (cited as the main cause by 86% of respondents). Refining cereals removes a large proportion of protein and protective vitamins, and the situation is aggravated by declining nutrient density in industrial grain and vegetables.
