“…Yet, depending on the prevailing biophysical conditions, negative interactions between the trees and the inter-tree crops (e.g. competition for limited resources, or the formation of adverse microclimatic conditions) may decrease crop yields and quality, necessitating the careful planning and designing of such systems (Yang et al, 2021). Yet, when judiciously designed, the planted trees may provide a range of regulating services, such as improved microclimate, soil erosion control, and C sequestration in addition to the provisioning (services) of logs, construction materials, and fuelwood (Lu et al, 2018; Santoro et al, 2020).…”

Land degradation and desertification are widespread across the world’s drylands. These processes are substantially affected by climatic change, with long-term and severe droughts on the one hand, and high intensity rainstorms and devastating floods on the other hand. Simultaneously, land-use change and mismanagement practices have led to processes of accelerated soil erosion, depletion of soil organic carbon pools, and the degradation of extensive drylands. Forestry has been accepted as an effective means for restoring degraded drylands, and for attaining a range of regulating, provisioning, supporting, and cultural ecosystem services. Specifically, forestry is widely perceived as an effective means for soil erosion control, organic carbon sequestration, microclimate improvement, and climate change mitigation. However, forestry in drylands often proves to generate substantial environmental challenges, resulting in deterioration of ecosystem functions and health. The objective of this essay is to review the challenges and opportunities induced by dryland afforestation and reforestation, and highlight the need to attain climate-smart strategies for establishing and managing these land-uses. Particularly, tree species invasion and allelopathy, which are common in dryland forestry projects, jeopardize species richness and diversity of native vegetation communities. Further, the challenges linked with tree invasiveness necessitate predicting the distribution of potentially invasive species and foreseeing their impacts on the recipient ecosystems under projected climate change scenarios. The effect of allelopathy is significant under limited water availability conditions and is expected to be determined by the expanding drylands and intensifying aridity worldwide. Therefore, judicious selection of tree species should not only focus on ones with high water-use efficiency, low flammability, high pest resistance, and fast growth, but also on low invasiveness and allelopathic capacities. Insights of this essay may be used by land managers, stakeholders, and policy makers involved in environmental development of drylands.

“…After the age of 3 years, the teak stands are dense enough, so that it is no longer possible to plant crops that are not shaded tolerant. The complementarity of resources capture by trees and crops in agroforestry systems is a major factor that improves productivity [10,11], because the competition for resources is a major factor that limits the productivity of and revenue from agroforestry systems, the competition for resources between trees and crops has attracted the attention of researchers [11][12][13]. This competition between crops and trees includes competition between aboveground and belowground parts in an agroforestry system [14].…”

“…The reduced yield of understory crops in agroforestry systems is usually caused by the shading of trees; the photosynthetic characteristics of understory crops are adversely affected by intercropping with trees, and this effect is greater when understory crops are nearer to trees [15,16]. Intercropping with trees usually inhibits the growth of crop roots in dryland agroforestry systems [11].…”

Forests are expected to provide social and economic benefits to the community, in addition to the ecological benefits. The production forest in Gunungkidul which is managed by the Yogyakarta Forest Management Unit (FMU) is dominated by teak (Tectona grandis) and cajuput (Melaleuca cajuput) as the main crop. Gunungkidul is dominated by marginal land with low nutrients, low pH, and low organic matter. Agroforestry is known as a promising option in land use systems considering multi-strata canopy combinations and multi-products. This study aimed to compare two types of agroforestry with two main crops; teak and cajuput tree concerning cultivation, economy, and social benefits. The method used was in-depth interviews with the forest community and FMU Yogyakarta. The number of respondents was 60 forest farmers, from which 30 farmers each for the two agroforestry patterns, and the staff of FMU Yogyakarta consisted of 2 people from the management staff and 2 people from the field staff. The main data were forest farmer activities in state forests, including income and expenses during cultivation. In addition, the data includes perceptions and data regarding the advantages of the community forests (CF) program from the aspects of the economy, social (preference), and cultivation. The results showed that economically, cajuput tree-based agroforestry activities contributed more income than teak-based agroforestry. In the cultivation aspect, farmers prefer cajuput stands because they have wider open land. Likewise, FMU considers cajuput tree cultivation easier and the risk of theft (i.e. illegal cutting) smaller. However, teak agroforestry is more environmentally friendly than cajuput, for example, teak litter can be a source of natural organic fertilizer. Therefore, it is necessary to find a technical solution to deal with this difference of interests to secure the success of agroforestry implementation such as suitable spacing, the combination of cropping patterns, and intensive cultivation.

“…However, their use is still not generalized in the Mediterranean region, and more incentives are needed to encourage farmers to adopt this practice. In this sense, alley cropping could be a suitable strategy to achieve environmental benefits but also increasing land profitability by production of complementary commodities (Swieter et al, 2021;Yang et al, 2021). Alley cropping is the agronomic strategy of growing annual or perennial crops in the alleys of tree orchards to increase farmer revenues, while increasing the land productivity by producing several commodities in the same space during the same year (Tsonkova et al, 2012;.…”
