Homegarden agroforestry systems in achievement of Sustainable Development Goals. A review

Homegarden, a type of agroforestry system, is one of the earliest thriving traditional food systems reported. Studying the contribution of homegardens in the context of Sustainable Development Goals (SDGs) is crucial when the COVID-19 pandemic has hindered the achievement of many of the crucial SDGs. In this review, we focused on 94 peer-reviewed papers on homegardens from 2010 to 2021 to interrelate them with the corresponding targets and indicators of each SDG. The SDGs were classified into five categories, each focusing on a specific aspect: Category 1 (SDGs 1-5, poverty dimension), Category 2 (SDGs 6-9, development infrastructures), Category 3 (SDGs 10-12, sustainable production and consumption), Category 4 (SDGs 13-15, green infrastructures), and Category 5 (SDGs 16-17, green institutions). The distribution of the 94 papers analyzed was 92%, 23%, 33%, 51%, and 50% in each of the SDG categories, respectively. Category 1 and SDG 2 were found to be most realized in the homegarden literature. Important observations were found that highlight homegardens' probable use in providing food security, nutritional needs, health and wellness, preservation of agrobiodiversity, and enduring sustainability. Homegardens appear to be an important strategy for attaining the SDGs and can be accomplished with proper planning, in addition to taking into consideration how the traditional societies have sustained it for long.
