“…Indeed, out of the selected documents, only 6 deal with animal production (Aziza et al, 2009;Dhraief et al, 2019;Dolinska, 2017;Hamad et al, 2020;Le Gal et al, 2010;Stilt, 2018), and one with fisheries (Fouad et al, 2018). As for crop production, the addressed crops include citrus (Ben Rejeb et al, 2020), date palms (Bouissil et al, 2020;Khaled and Segni, 2016;Souli et al, 2020), wheat (Bouzid et al, 2020;Jovanovic et al, 2020), potato (Bouzid et al, 2020;Jovanovic et al, 2020), and tomato (Badaoui et al, 2019;Codron et al, 2007;Dolinska et al, 2020). In general, the focus is on cash, export crops rather than staple ones.…”

“…Callieris et al (2016) are among the few scholars that focus on consumption and analyze Tunisian consumer behaviors towards organic agri-food products. Interestingly, some articles deal with agri-food waste management (Badaoui et al, 2019;Khaled and Segni, 2016;Lin et al, 2013;Souli et al, 2020).…”

“…Examples include precision agriculture (Singh, 2018), agro-ecology (Ameur et al, 2020), Saharan agriculture (Daoudi and Lejars, 2016;Naouri et al, 2015), conservation agriculture (King, 2008;Labbaci et al, 2015;Singh, 2018) or mixed animal-crop farming (King, 2008;Le Gal et al, 2010). Process innovations also include methods for the conversion and consequent use of different types of waste, such as anaerobic digestion (Souli et al, 2020), drying in solar greenhouses (Badaoui et al, 2019), fermentation for the production of bioethanol (Khaled and Segni, 2016). These innovative processes generally refer to the second generation waste valorization and re-use strategies for the production of high-value products (e.g.…”
