“…One study reveals a negative impact of the adoption of modern varieties on farmers' income. This is Coromaldi et al (2015), who found out that in Uganda, adopters of modern varieties of staple crops (mainly maize) lost, on average, 11.2% in crop profits per capita.…”

Crop diversification is one of the most cost‐effective way of reducing uncertainties in farmer's income, especially among poor smallholder farmers. However, poverty is a complex concept, which includes more dimensions than only income. This review investigates the contribution of crop diversification to Sustainable Development Goal 1(SDG1) “No poverty” by also considering other dimensions of poverty, namely gender equality, food security and nutrition, and vulnerability to climate change. It demonstrates that the contribution of crop diversification to food security and nutrition, gender equality, and reduction of poor farmers' vulnerability to climate change has not been properly researched. Several factors across the studies analysed were found to influence the implementation of crop diversification, but these were hardly connected to poverty reduction. New research and policy impact evaluation methods that follow a sustainability approach perspective to poverty need to be undertaken in order to assess the contribution of crop diversification to SDG1.

“…Furthermore, crop rotations with a higher share of cereals show a negative impact on yield stability of winter wheat, especially for wheat monocultures. In contrast, diverse crop rotations with favorable preceding crops (e.g., legumes) affect the yield stability of the main crop winter wheat positively [15][16][17][18][19]. Beyond that, cultivar choice is an effective tool in farming practice, which is used to support yield stable wheat production [3,12,20].…”

Most of the available research studies have focused on the production of high grain yields of wheat and have neglected yield stability. However, yield stability is a relevant factor in agronomic practice and, therefore, is the focus of this comprehensive survey. The aim was to first describe the importance of yield stability as well as currently used practical management strategies that ensure yield stability in wheat production and secondly, to obtain potential research areas supporting yield stability in the complex system of agronomy. The target groups were German farmers with experience in wheat production and advisors with expertise in the field of wheat cultivation or research. A sample size of 615 completed questionnaires formed the data basis of this study. The study itself provides evidence that the yield stability of winter wheat is even more important than the amount of yield for a large proportion of farmers (48%) and advisors (47%). Furthermore, in the view of the majority of the surveyed farmers and advisors, yield stability is gaining importance in climate change. Data analysis showed that site adapted cultivar choice, favorable crop rotations and integrated plant protection are ranked as three of the most important agronomic management practices to achieve high yield stability of wheat. Soil tillage and fertilization occupied a middle position, whereas sowing date and sowing density were estimated with lower importance. However, yield stability is affected by many environmental, genetic and agronomic factors, which subsequently makes it a complex matter. Hence, yield stability in farming practice must be analyzed and improved in a systems approach.

“…Heirlooms are known for their great trait diversity, e.g., for color, shape, size, growth, height, phenology, yield, and flavor. This wide diversity-which is the main feature capturing the attention of consumers seeking unique, nutritious, local food sources-also plays a key role in the risk management strategy of farmers if modern-bred cultivars are unsuitable for the local context [14]. Crop heterogeneity and diversity should therefore be included in a national asset strategy by rural development policy-makers, because such a valuable genetic endowment will be useful for further breeding.…”

The burdens of malnutrition, protein and micronutrient deficiency, and obesity cause enormous costs to society. Crop nutritional quality has been compromised by the emphasis on edible yield and through the loss of biodiversity due to the introduction of high-yielding, uniform cultivars. Heirloom crop cultivars are traditional cultivars that have been grown for a long time (>50 years), and that have a heritage that has been preserved by regional, ethnic, or family groups. Heirlooms are recognized for their unique appearance, names, uses, and historical significance. They are gaining in popularity because of their unique flavors and cultural significance to local cuisine, and their role in sustainable food production for small-scale farmers. As a contrast to modern cultivars, heirlooms may offer a welcome alternative in certain markets. Recently, market channels have emerged for heirloom cultivars in the form of farmer-breeder-chef collaborations and seed-saver organizations. There is therefore an urgent need to know more about the traits available in heirloom cultivars, particularly for productivity, stress tolerance, proximate composition, sensory quality, and flavor. This information is scattered, and the intention of this review is to document some of the unique characteristics of heirloom cultivars that may be channeled into breeding programs for developing locally adapted, high-value cultivars.
