This study aimed to characterize the consumption, budget and food security of nine cocoa-growing households in two villages on the northern outskirts of the Odzala-Kokoua National Park (OKNP) in Congo. An inventory of the mammalian communities present in the village agroforests was carried out. These are home to at least 14 species of mammal, particularly small mammals such as rodents. As a result, the agroforests are defaunated. Households consume more fish than bushmeat. Household consumption can be explained by the greater availability of fish compared with bushmeat. Similarly, household preferences and the lower cost of fish compared with bushmeat explain the higher consumption of fish. The majority of animal protein consumed by households was purchased. All households derived a large part of their income from plantain sales. In some cases, income from plantain sales exceeded that from cocoa. Cocoa contributed more than 20 % of income for only four households. Households' main expenditure is on labor, followed by food. The contribution of bushmeat to income is low, with the exception of the household that did not harvest cocoa during the study. Labor costs for cocoa harvesting are four times higher than for the harvesting of food crops.NTFPs are not an important source of household income. . However, self-consumption of Gnetum spp, palm nuts in the form of mouambe and chilli pepper (Capsicum sp) is very important for households. The Household Dietary Diversity Score (HDDS) showed that a third of households were food-secure, while the others experienced periods of stress. According to the proportion of the household budget spent on food, all households are food-secure.The state of food security was independent of household wealth.

The negative impacts of global warming and global environmental pollution due to fossil fuels mean that the main challenge of modern society is finding alternatives to conventional fuels. In this scenario, biofuels derived from renewable biomass represent the most promising renewable energy sources. Depending on the biomass used by the fermentation technologies, it is possible to obtain first-generation biofuels produced from food crops, second-generation biofuels produced from non-food feedstock, mainly starting from renewable lignocellulosic biomasses, and third-generation biofuels, represented by algae or food waste biomass.Although biofuels appear to be the closest alternative to fossil fuels, it is necessary for them to be produced in competitive quantities and costs, requiring both improvements to production technologies and the diversification of feedstock. This Special Issue is focused on technological innovations, including the utilization of different feedstocks, with a particular focus on biethanol production from food waste; different biomass pretreatments; fermentation strategies, such as simultaneous saccharification and fermentation (SSF) or separate hydrolysis and fermentation (SHF); different applied microorganisms used as a monoculture or co-culture; and different setups for biofuel fermentation processes.The manuscripts collected represent a great opportunity for adding new knowledge to the scientific community as well as industry.

As a dynamic interface between agriculture and forestry, agroforestry has only recently been formally recognized as a relevant part of land use with ‘trees outside forest’ in important parts of the world—but not everywhere yet. The Sustainable Development Goals have called attention to the need for the multifunctionality of landscapes that simultaneously contribute to multiple goals. In the UN decade of landscape restoration, as well as in response to the climate change urgency and biodiversity extinction crisis, an increase in global tree cover is widely seen as desirable, but its management by farmers or forest managers remains contested. Agroforestry research relates tree–soil–crop–livestock interactions at the plot level with landscape-level analysis of social-ecological systems and efforts to transcend the historical dichotomy between forest and agriculture as separate policy domains. An ‘ecosystem services’ perspective quantifies land productivity, flows of water, net greenhouse gas emissions, and biodiversity conservation, and combines an ‘actor’ perspective (farmer, landscape manager) with that of ‘downstream’ stakeholders (in the same watershed, ecologically conscious consumers elsewhere, global citizens) and higher-level regulators designing land-use policies and spatial zoning.
