Sustainable practices have gained significant popularity, to the extent that it's challenging to envision a sourcing company that doesn't prioritize, aim for, or at the very least, pledge to implement sustainable practices when procuring raw agricultural products. Among these products, coffee beans stand out prominently. What are the key sustainable practices currently under debate? Let's delve into the realm of conservation coffee.
When discussing sustainable practices within the coffee industry, we often consider alliances and associations dedicated to promoting them, such as the Rainforest Alliance, Global Coffee Platform, and Fair Trade International. These organizations not only prioritize environmental practices but also focus on broader aspects like social responsibility and economic viability. However, conservation coffee farming places a specific emphasis on environmental impact, particularly on environmental conservation and biodiversity preservation within farming practices. Conservation coffee prioritizes biodiversity-friendly farming techniques, sourcing coffee in a manner that preserves forestry, and cultivating coffee under shade to promote a healthier ecosystem. The intrigue arises when we delve into the latter aspect.
Coffee cultivation offers two contrasting methods: shade-grown and sun-grown, each sparking discussions regarding their environmental impact. Advocates for shade-grown coffee argue that it preserves natural biodiversity and forestry, providing a lush canopy above the coffee plants. This natural setting enriches the soil with essential nutrients. In contrast, sun-grown coffee requires clearing vast expanses of land, disrupting natural habitats. Additionally, these plants often demand more water and fertilizers to thrive. Despite their slower growth, shade-grown beans have nuanced and indulgent flavors. However, their lower yield makes them costlier and less efficient to produce, contrasting with the faster growth of sun-grown beans, which meet the escalating demand for coffee but may come at a greater environmental cost. The instant coffee we commonly consume is predominantly made from sun-grown Robusta beans, which makes it more affordable.
An opinion exists, however, that shadow-grown coffee, while offering benefits, can also present challenges. Despite its high prices, smallholder organic coffee growers struggle to maintain yields due to compost needs, disease control limitations, and challenges in shaded environments (H. Van Der Vossen). While some advocate for organic farming sustainability, others propose achieving economic and agronomic sustainability through conventional practices and post-harvest methods. Furthermore, some studies indicate that coffee yield isn't solely determined by the presence or absence of shade. Rather, it's the particular species of coffee plant that has a notable impact, as demonstrated in research conducted on coffee farming in Ethiopia's forests (Aerts et al., 2011). This may suggest that growing coffee beans in full sun doesn't automatically result in lower quality taste. However, more research is needed to fully understand the implications.
Nevertheless, an increasing number of countries have begun to embrace conservation coffee practices, particularly through the shadow-grown method of coffee cultivation. This trend is evident in countries like Indonesia, Ethiopia, Brazil, Mexico, and others. Additionally, the topic of conservation coffee, as well as the debate between shadow versus sun-grown coffee beans, is gaining more attention and discussion, helping us gain a deeper understanding of the world of coffee beans.
