Special Issue Information

Dear Colleagues,

Agriculture is pivotal for the policies aimed at fostering sustainability and socioecological resilience, in line with the frame tailored by the Ecosystem Millennium Assessment (EMA, ecosystem services’ concept) and by the Sustainable Development Goals (UN, SDGs). Currently, 70% of the rural activities in the world are covered by farming systems of a small-medium size. Many of these are family farming systems, which are especially seen to provide a consistent amount of food and commodities while ensuring fundamental ecosystem services. Most often, such systems are planned for multifunctional purposes and pay much attention to conservation agriculture, agroforestry and diversification of crops and non-food products. In addition, there is the key component of biodiversity preservation along with the adoption of agroecological practices. Furthermore, given that their features are disposed to the intergenerational viability, family farming systems are likely better enabled to promote local uniqueness, thus producing an indigenous heritage of locally designed solutions, practices, and knowledge sharing. With reference to the interrelated biotic and abiotic crises that humanity faces and is facing (e.g., the impacts of climate change and the COVID-19 epidemic), various studies suggest a higher socioecological resilience for those anthropic systems where the common characteristics are diversity, synergy, efficiency, recycling, co-creation and sharing of knowledge, human and social values, culture and food traditions, responsible governance, circular and solidarity economies. These are certainly the keywords that the FAO adopts in identifying the agroecological approach, although scientific research on the real potentialities of agroecology is lacking and mostly confined to the grey literature and to the empiricism of applied experiences. This lack of information seems particularly true of scales of ecological complexity larger than the ecosystem or the farm, requiring focused scientific efforts on the landscape and regional levels to meet two major aims: 1) increasing our holistic comprehension of socioecological systems; and 2) empowering the communities towards effective, locally-based capacity building processes, in order to implement more resilient, environmentally friendly, and socially fair systems.

In order to accomplish these aims, the present Special Issue aims to highlight the state of the art in our present capability to understand and apply the agroecological approach in real life. Particularly, it seems important to engage scientific contributions covering the full range of basic aspects for a sound handling of the agroecology discipline. Such an effective handling must meet the recognition of the following: the common characteristics of agroecological systems as well their foundational practices and innovation approaches; the context features referring to a unique indigenous blend of environment and culture; the enabling environment made of responsible governance and circular and solidarity economies, elements which are fundamental to any sustainability target. Contributions covering and/or addressing one or more of these themes will be most welcome, and surely, beneficial to human ideals in general.

The production of residual biomass, such as vine pruning, presents environmental problems since its elimination is usually carried out through the uncontrolled burning of the remaining materials and with the emission of greenhouse gases without any counterpart. The use of these residues to produce biochar presents several advantages. In addition to the more common energy recovery, other conversion ways allowing new uses, such as soil amendment and carbon sequestration, can be analyzed as options as well. In the present study, vine pruning biomasses are characterized to evaluate the behavior of the different constituents. Then, the different possible applications are discussed. It is concluded that materials resulting from the pruning of vineyards have excellent characteristics for energy recovery, with an increment of more than 50% in the heating value and almost 60% in the carbon content when carbonized. This recovery procedure contributes to creating new value chains for residual materials to promote sustainable practices in the wine sector. Full article

Seaweed extract biostimulants are among the best modern sustainable biological plant growth promoters. They have been proven to eliminate plant diseases and abiotic stresses, leading to maximizing yields. Additionally, they have been listed as environmentally friendly biofertilizers. The focus of the present research is the use of a commercial seaweed biostimulant as an eco-friendly product (formally named True Algae Max (TAM). During the 2017 and 2018 seasons, five treatments of various NPK:TAM ratios were applied via regular fertigation, namely a conventional treatment of 100% NPK (C0) alongside combinations of 25%, 50%, 75%, and 100% (C25, C50, C75, and C100) of TAM, to evaluate the effectiveness of its bioactive compounds on enhancing growth, yield, and NPK content of cucumber (Cucumis sativus) under greenhouse conditions. TAM is rich in phytochemical compounds, such as milbemycin oxime, rhodopin, nonadecane, and 5-silaspiro [4.4]nona-1,3,6,8-tetraene,3,8-bis(diethylboryl)-2,7-diethyl-1,4,6,9-tetraphenyl-. Promising measured parameter outcomes showed the potentiality of applying TAM with and without mixes of ordinary NPK application. TAM could increase cucumber yield due to improving chemical and physical features related to immunity, productivity, and stress defense. In conclusion, it is better to avoid applying mineral fertilizers, considering also that the organic agricultural and welfare sectors could shortly depend on such biotechnological tools and use them to fulfill global food demands for improved sustainability.

As the extent of secondary forests continues to expand throughout the tropics, there is a growing need to better understand the ecosystem services, including carbon (C) storage provided by these ecosystems. Despite their spatial extent, there are limited data on how the ecosystem services provided by secondary forest may be enhanced through the restoration of both ecological and agroecological functions in these systems. This study quantifies the above- and below-ground C stocks in a non-native secondary forest in Hawaiʻi where a community-based non-profit seeks to restore a multi-strata agroforestry system for cultural and ecological benefits. For soil C, we use the equivalent soil mass method both to estimate stocks and examine spatial heterogeneity at high resolution (eg. sub 5 m) to define a method and sampling design that can be replicated to track changes in C stocks on-site and elsewhere. The assessed total ecosystem C was ~388.5 Mg C/ha. Carbon stock was highest in trees (~192.4 Mg C/ha; ~50% of total C); followed by soil (~136.4 Mg C/ha; ~35% of total C); roots (~52.7 Mg C/ha; ~14% of total C); and was lowest in coarse woody debris (~4.7 Mg C/ha; ~1% of total C) and litter (~2.3 Mg C/ha; <1% of total C). This work provides a baseline carbon assessment prior to agroforest restoration that will help to better quantify the contributions of secondary forest transitions and restoration efforts to state climate policy. In addition to the role of C sequestration in climate mitigation, we also highlight soil C as a critical metric of hybrid, people-centered restoration success given the role of soil organic matter in the production of a suite of on- and off-site ecosystem services closely linked to local sustainable development goals.
