“…Theobroma cacao , Theobroma grandiflorum , Manihot sp., and palms such as Euterpe spp. are some of the species that can be associated with peach palm [ 50 , 51 ]. The possibility of culture with other plants, such as Coffea canephora and Coffea arabica , peanut, rice, and sorghum, has also been studied.…”

The extraction and commercialization of palm hearts is the most profitable activity involving the peach palm (Bactris gasipaes), while consumption of its fruits is limited to Amazonian communities. The excessive attention paid to the implementation of germplasm banks contributed to the lack of development of high-performance varieties, limiting the production and consumption of peach palm fruits and by-products. In addition, with the fragmentation of the Amazonian rainforest, wild populations are in danger of extinction. The species domestication, initiated by Native Amazonians, generated a large variety of peach palm populations, as evidenced by the diversity in fruit sizes and quality. Some advances in agronomic traits also took place. However, more research needs to be conducted to understand the implications of climatic changes on plant physiological performance. Indeed, the key point is that the exploitation of the full potential of B. gasipaes has not been completely exploited. Therefore, understanding the state-of-the-art research on the peach palm with a focus on its underutilized resources is essential for expanding plantations and, consequently, promoting the market expansion of the peach palm as a fruit crop.

“…To increase tree cover, farmers should understand plant species as well as planting niche preferences, as well as provide and manage seedlings properly. Moreira et al (2012) also state that plants in the same ecosystem differ in nutritional uptake and nutritional requirements. A strategic specie combination is therefore necessary for the sustainable management of cocoa agro-forest land spaces.…”

“…The tendency of shade trees to compete with cocoa crop trees for soil nutrients is eminent and of great concern. Moreira et al (2012), in their study, has proven that a strategic selection of plant species combination for agroforestry is necessary to maintain efficient utilization of soil nutrient due to different nutrient requirement from different species. Cocoa crops have fine roots which means they mainly utilize the above-ground soil nutrients so any shade tree species or tropical plants that have fine roots will compete with the cocoa crops for soil nutrients, and deep-rooted trees would not compete with the cocoa trees (Niether et al 2019).…”

Agroforestry is a climate-smart strategy adopted in cocoa farms to help cocoa crops adapt to climate change, maintain biodiversity, and improve cocoa yield. Meanwhile, its sustainability is of major concern to farmers. This study brings to the fore the common and persistent factors that pose a threat to the sustainability of cocoa agroforestry, presented through a systematic literature review approach, and further discussed using the United Nations’ Sustainable Development Goals (SDGs) model as the focal point. A number of serious limitations have been identified in the study as limiting the sustainability of cocoa agroforestry, including a lack of technical support for planting trees, an increase in pests and diseases, the intense competition for nutrients between shade trees and cocoa trees, weak land tenure policies, and numerous other factors. The eleven identified limitations were further categorized and analyzed under Environmental, Economic, and Social Limitations, and policy directions were drawn and discussed. Based on the findings of the study, Cocoa Agroforestry must not only support both cocoa production and forest conservation simultaneously but also satisfy all three Sustainable Development Goals. For Cocoa Agroforestry to become an agricultural practice that is sustainable, it must address the environmental limitations, economic limitations, and social limitations simultaneously.

Fertilizer Adoption by Smallholders in the Brazilian Amazon: Farm-level Evidence

Multiple constraints prevent smallholders from adopting fertilizers even with regional supply of agricultural inputs expanding and soils being weared-out. Using comprehensive farm-level data from the eastern Brazilian Amazon, we found that market proximity had a significant positive correlation with fertilizer adoption, even after controlling for liquidity, land tenure, education, experience and access to rural extension services. Nevertheless, few smallholders completely replaced nutrients from vegetation with fertilizers. Instead, we found that a hybrid system that combines nutrients from vegetation and fertilizers was approximately twice as common as exclusive fertilizer use. We suggest that the option for this diversified "nutrient portfolio" may result not only from a lack of capital or knowledge regarding return on fertilizer use, but also from the need to adapt to the economic constraints facing smallholders and minimize risk. Results indicate that a rural extension program aimed at supporting a rapid and complete replacement of ashes from vegetation by fertilizers could prove unsuccessful for Amazonian smallholders
