Special Issue Information

Dear Colleagues,

The rapid expansion of tropical plantation crops (e.g., oil palm, rubber, sugarcane, timber, cocoa, coffee, etc.) has led to the emergence of agricultural commodities of strategic global importance, which have profoundly transformed landscapes and livelihoods in the tropical world.

The coexistence of such booming cash crops with the last global biodiversity hotspots poses recurring questions regarding the sustainability of farming practices. Cropping systems have changed little since the industrialization of plantation crops one century ago, and plantation management now needs to meet the dual challenge of conserving biodiversity and engaging in sustainable agricultural development through the adoption of agroecological practices.

Research in social sciences has also questioned the inclusion of major stakeholders, such as smallholding farmers. The certification of sustainable practices and the modes of governance that are capable—at the local and national levels—of guaranteeing a credible sustainability of agricultural practices are also key research topics.

With genomic resources becoming increasingly available for most of the plantation crops (high-throughput sequencing and genotyping, chips development), the exploration of the genetic basis of complex traits, such as yield, tolerance to diseases, or resilience to climate change, is now under way. Consequently, the availability, treatment, and sharing of large amounts of data are currently reshaping breeding strategies.

The evolution of cocoa farming was quickly confronted with the development of pests and diseases. These sanitary constraints have shaped the geographical distribution of production over the centuries. Current climate change adds an additional constraint to the plant health constraints, making the future of cocoa farming more uncertain. Climate change is not only affecting the areas where cocoa is grown for physiological reasons, particularly in relation to changes in water regimes, but also affects the distribution of pests and diseases affecting this crop. These different points are discussed in the light of the trajectories observed in the different cocoa-growing areas. The breeding programs of cocoa trees for sustainable resistance to plant health constraints and climate change are therefore particularly important challenges for cocoa farming, with the other management practices of plantations.

Physicochemical, Nutraceutical and Sensory Traits of Six Papaya (Carica papaya L.) Cultivars Grown in Greenhouse Conditions in the Mediterranean Climate

Six papaya (Carica papaya L.) cultivars, grown in a Mediterranean climate under greenhouse conditions, were screened for physicochemical properties, antioxidant capacity, nutritional and sensory characteristics. The fruits, harvested with more than 50% of yellow surface (between 60% and 77%) were tested for carotenoids content, phenolic content, reducing activity (ABTS) and cellular antioxidant activity (CAA50). The physicochemical traits were measured in terms of the titratable acidity and soluble content whereas proximal composition along with moisture, fats, total sugar, ash, vitamin A, C and E content. Moreover, the sensory profile was analyzed by a semi-trained panel. Although the six analyzed cultivars reached qualitative characteristics to satisfy market needs, significant differences among them were found in a genotype-dependent manner. In particular, Cartagena and Maradol cultivars evidenced the highest values of minerals and vitamins, carotenoids, polyphenols, ABTS and CAA50 and reached the best commercial requisites (size, total soluble solids content/titratable acidity ratio). As for sensory analysis, we observed significate differences only for sweetness, juiciness, odor and flavor of peach and exotic fruits whereas descriptors related to unpleasant defects or sensations always have very low scores in all the observed cultivars. These results highlight the possibility of obtaining quality papaya fruits in a Mediterranean climate using greenhouse growing. Full article

Sugarcane is an important industrial crop because it is the major source of white sugar. It is also one of the crops for the alcohol and biofuel industries. Disease-causing organisms can significantly decrease the productivity of sugarcane plants and sugar quality. Among the disease-causing organisms, Colletotrichum falcatum Went causes the most significant economic loss (5–50%) in the sugarcane production due to red rot disease. This loss results in only 31% sugar recovery. It is reported that C. falcatum can kill sugarcane plants. Currently, there is no sustainable way of preventing red rot disease from spreading in sugarcane plantations. Many popular sugarcane varieties are no longer used in sugarcane cultivation because of their susceptibility to C. falcatum. The objectives of this manuscript were to: (i) summarize existing approaches for the early detection of red rot disease and controlling techniques of red rot disease in the field and laboratory and (ii) assess red rot disease control effectiveness so as to propose better methods for mitigating the spread C. falcatum. If our proposition is adopted or practiced, it could significantly contribute to the mitigation of C. falcatum infection in the sugarcane industry. This could enable achieving sustainable cultivation of sugarcanes to guarantee the sustainability of the sugar industry in the tropics and the subtropics. Full article
