Abstract. Suryanto P, Sadono R, Yohanifa A, Widyawan MH, Alam T. 2021. Semi-natural regeneration and conservation in agroforestry system models on small-scale farmers. Biodiversitas 22: 858-865. The regeneration capacity can provide an overview of the abundance of species so that it can be used to determine the potential and opportunities for the sustainability of agroforestry systems. The purpose of this study was to determine the capacity of semi-natural regeneration in agroforestry system models for small-scale farmers. The study was carried out in Banaran Sub-district, Playen District, Gunungkidul Regency, Special Province of Yogyakarta, Indonesia. The observation was conducted on plant diversity, floristic composition, and agroforestry contribution. The results showed that the mixed cropping (MC) model had a higher total of individuals and diversity compared to the trees along with border (TAB) model in the sapling and seedling level. The MC model was relatively shorter to the waiting time of harvesting compared to the TAB model. The MC models weakness was the relatively high competition and the lack of opportunities to growing annual crops. The TAB model had an advantage in developing annual crops in an agroforestry system, while longer in waiting time for harvesting perennial crops. This study recommends annual pruning in the MC model for optimal stand growth, while in the TAB model, it is the enrichment planting in sapling and seedling levels.

In recent years, agroforestry has gained increasing attention as an option to simultaneously alleviate poverty, provide ecological benefits, and mitigate climate change. The present study simulates small-scale farmers’ agroforestry adoption decisions to investigate the consequences for livelihoods and the environment over time. To explore the interdependencies between agroforestry adoption, livelihoods, and the environment, an agent-based model adjusted to a case study area in rural Indonesia was implemented. Thereby, the model compares different scenarios, including a climate change scenario. The agroforestry system under investigation consists of an illipe (Shorea stenoptera) rubber (Hevea brasiliensis) mix, which are both locally valued tree species. The simulations reveal that farmers who adopt agroforestry diversify their livelihood portfolio while increasing income. Additionally, the model predicts environmental benefits: enhanced biodiversity and higher carbon sequestration in the landscape. The benefits of agroforestry for livelihoods and nature gain particular importance in the climate change scenario. The results therefore provide policy-makers and practitioners with insights into the dynamic economic and environmental advantages of promoting agroforestry.

Small Scale Farmers

Agroforestry systems, the planting of perennial trees and/or shrubs with annual agronomic crops or pasture, have been proposed as more environmentally benign, alternative systems for agricultural production in both temperate and tropical regions of the world. Agroforestry provides a number of environmental benefits as confirmed by scientific literature. The four major environmental benefits of agroforestry are (1) climate change mitigation through carbon sequestration, (2) biodiversity conservation, (3) soil health enrichment, and (4) air and water quality improvement. In addition to environmental benefits, the economic benefits of multiple crops within agroforestry systems have also generated interest in their adoption by farmers the world over. The major negative impacts come from conversion or degradation of forests following certain traditional practices, which may not fit in the definition of modern agroforestry. Challenges remain for widespread adoption of agroforestry, particularly in the temperate world; however, a new resurgence of interest in this land-use practice among small-scale farmers has shed light on a path toward its possible success. Past evidence clearly indicates that agroforestry, as part of a multifunctional working landscape, can offer not only economic return, but also a number of ecosystem services and environmental benefits for a sustainable society.

Land Condition

Design of agroforestry has the objectives of improving the system which has been existing and providing directives for agribusiness on the basis of physical, economical, and socio-cultural condition. Design of a system is inevitably related with pre-diagnosis and diagnosis activities which are aimed at discovering the existing constraints and problems inside the system, followed by technological intervention for system improvement and determining the best agroforestry system in critical land condition. Method used in this study was identifying the existing agroforestry system, followed by evaluation of land suitability, financial analysis and community social analysis. This study found three agroforestry systems based on the existing components, namely agrisilviculture, silvopasture, and agrisilvopasture. Evaluation of land suitability showed that in general, land suitability ratings for woody crops and perennial crops were categorized as moderately suitable (S2), while those for annual crops / non rice food crops were categorized as marginally suitable (S3). Results of financial analysis showed that all existing agroforestry system are feasible to be practiced, with highest benefit cost ratio 2.7 was found in agrisilvopasture system. On the basis of landscape consideration, species of Non-MPTs were more adapted if they were planted in hill ridge, while that of species of MPTs and perennial crops in slope and valley, and that of annual crops in valley. Key words: agroforestry, land suitability, critical land, design

Homegardens contain agroforestry systems that provide diverse resources for familyconsumption in rural communities. The aim of this study was to perform an ethnobotanical inventory of the tree speciesand their uses in the homegardens of two small-scale rural farming communities situated near the Mata Seca State Park,Minas Gerais, Brazil, and to understand the potential role of these agroecosystems in the conservation of native treespecies. Local knowledge about species used was assessed using free lists with 20 small-scale farmers selected using thesnowball sampling technique in each community. All shrub and tree species with a circumference at the soil level  10 cmwere sampled in each homegarden. We confirmed that most plant species listed provided food (48.3%) and shade (35.6%),showing the importance of fruit trees and evergreens in the homegarden flora in this local semi-arid context. Other specieswere also cited as medicinal and ornamental plants. Besides that, some species listed were used for construction, fuel,fodder, fertilizer and other uses. Amongst the 87 tree species, 44 are Brazilian natives, and 23 can be found in the dryforests of the region. These results showed that homegardens can contribute to conservation and enhancement of localbiodiversity functioning as a reservoir of species with different biogeographic origins, including regionally endemic andnative trees. Furthermore we conclude that homegardens are important sources of plant resources for home consumptionand contribute towards a balanced diet and to the welfare of the people living in the communities of north Minas Gerais’semi-arid region.

A field experiment was conducted from May 2017 to February 2018 at the research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University to evaluate the performance and profitability of three seasonal (Broccoli, Cabbage and Okra) and two annual crops (ginger and turmeric) in lemon-based agroforestry systems. The experiment was laid out in a Randomized Complete Block Design (RCBD) and replicated thrice. For seasonal crops the treatments were sole field (T0), 50 cm distance from tree base (DTB) with ginger (T1), 50 cm DTB with turmeric (T2), 100 cm DTB with ginger (T3) and 100 cm DTB with turmeric (T4). For annual crops (ginger and turmeric) the treatments were sole field (T0) and four distance regimes (50, 100, 150 and 200 cm) from the lemon tree base in agroforestry systems. The results of the study revealed that the yield of seasonal crops decreased and the yield of annual crops and perennial trees increased in agroforestry than respective sole cropping systems. The yield performance of crops component was significantly decreased with the decreasing distance towards tree base in agroforestry systems. The economic analysis showed that the net return, benefit-cost ratio (BCR) and land equivalent ratio (LER) was higher in the lemon-based agroforestry system than sole cropping. Therefore, the cultivation of cabbage, broccoli, okra, ginger and turmeric under lemon-based agroforestry systems are economically profitable.

Speciality crops are great alternative cash crops for small scale farmers. Small scale farmers are constantly searching for viable economic crops to grow. We have been conducting applied research on the production and marketing of culinary herbs, oriental vegetables, colored peppers, and muskmelons to name a few. These crops show excellent potential for southern Ohio. Field demonstration, seminars, and surveys were used to gather and disseminate information on these speciality crops. More than 230 people attended our seminars on alternative cash crops. More than 150 people attended our field days. In addition, we had identified many chefs that are willing to purchase from local speciality crop growers. It will be a win-win situation for both chefs and growers. Growers will be able to maximize their profitability while chefs will receive fresh and unique produce. As a result of our research, we were able to show small scale growers what they can grow successfully and how they can market their crops for most profit. These applied research projects received a combined funding of $10000.00 from OSU Extension-Innovative Grant program. These projects are a great way to establish credibility among clients. We would also like to demonstrate how other extension agents can help their clients. A lecture utilizing slides and overhead transparencies will be the format of the seminar.
