Community forests with agroforestry planting systems have an influence on ecological aspects, such as: clean air, controlled erosion, carbon uptake, water management arrangements, ecosystems buffer, guarding ecological stability, and environmental protection. Therefore, in the management of community forests the present and future agroforestry planting systems must be able to pay attention to environmental principles. To realize this, the community forest agroforestry planting patterns must be healthy. This study aims to obtain the status of (current) health of community forests agroforestry planting systems in the area of East Lampung Regency. A case study of forest health analysis were carried out in Forest Health Monitoring (FHM) plots of community forests agroforestry planting systems in the East Lampung Regency. The number of FHM plots was made in four clusters. Parameters of indicators of community forest health agroforestry planting systems are tree growth, tree damage conditions, canopy conditions, and soil fertility. The stages of this study consisted of making a community forest measuring plot agroforestry planting systems, measuring indicators of community forest health agroforestry planting systems, processing and analysis, and assessing the health of community forests agroforestry planting systems. The results showed that the value of the status of public forest health conditions of agroforestry planting systems in the area of East Lampung Regency on average in good categories. This shows that community forests with agroforestry planting systems will produce healthy community forest health levels. Thus, community forests development in East Lampung Regency of Lampung Province is directed to agroforestry planting systems.

<strong>English</strong><br />Rural communities in Gunung Ciremai National Park (GCNP) are generally low income farmers. Farms that have long been adopted agroforestry farming systems through inter generation legacy. The existing agroforestry technology applied by the farmers remains the simple traditional technology, so that the crops yields and income are low. Understanding the determinants of farmers’ income is useful in formulating the appropriate policy for increasing farmers’ income. This study was aimed to analyze the level and determinants of the agroforestry farmers income in GCNP. This research was conducted in Kuningan and Majalengka Regency, West Java Province, in July to October 2017. The data was collected by interviewing 310 agroforestry farmers which were selected using the cluster random sampling technique with clusters consisted of the locations of farmer groups from agroforestry in the GCNP buffer zone. The data was analized using descriptive statistics and regression inferential statistics. The results show that the income of agroforestry farmers was low because of low agroforestry farmers’ capacity, weak extension support and weak leadership role of informal leaders. Supports of the forestry extension service and informal leaders' leadership roles are needed for enhancing the agroforestry farmers’ capacity in increasing their income.<br /><br /><br /><strong>Indonesian</strong><br />Masyarakat perdesaan di lingkungan Taman Nasional Gunung Ciremai (TNGC) umumnya adalah petani kurang sejahtera yang telah lama menekuni agroforestri turun-temurun. Penerapan teknologi pada sistem usaha tani agroforestri masih sederhana sehingga produktivitas tanaman masih rendah yang berdampak pada rendahnya pendapatan. Berbagai faktor dapat memengaruhi tingkat pendapatan petani agroforestri, sehingga perlu diungkap faktor-faktor yang dapat meningkatkan atau menurunkan pendapatan petani. Penelitian ini bertujuan untuk menganalisis besaran dan determinan pendapatan petani agroforestri di lingkungan TNGC. Penelitian ini dilakukan di Kabupaten Kuningan dan Majalengka, Provinsi Jawa Barat pada bulan Juli sampai Oktober 2017. Data diperoleh dari 310 orang petani yang dipilih berdasarkan cluster random sampling dengan klaster lokasi kelompok tani agroforestri di desa penyangga kawasan TNGC. Data dianalisis menggunakan metode statistik deskriptif dan statistik inferensial regresi. Hasil penelitian menunjukkan bahwa pendapatan petani agroforestri di lingkungan TNGC rendah karena rendahnya kapasitas petani agroforestri, lemahnya dukungan penyuluhan kehutanan, dan lemahnya peran kepemimpinan tokoh informal. Dukungan penyuluhan kehutanan dan peran kepemimpinan tokoh informal perlu ditingkatkan agar petani agroforestri memiliki kapasitas yang memadai dalam meningkatkan pendapatan mereka.

"Mountain Farming Systems’ Exposure and Sensitivity to Climate Change and Variability: Agroforestry and Conventional Agriculture Systems Compared in Ecuador’s Indigenous Territory of Kayambi People". Sustainability 11, n. 9 (7 maggio 2019): 2623. http://dx.doi.org/10.3390/su11092623.
Testo completoAbstract (sommario):
Smallholder farming is considered one of the most vulnerable sectors to the impacts of climate change, variability, and extremes, especially in the developing world. This high vulnerability is due to the socioeconomic limitations and high environmental sensitivity which affect the biophysical and socioeconomic components of their farming systems. Therefore, systems’ functionality and farmers’ livelihoods will also be affected, with significant implications for global food security, land-use/land-cover change processes and agrobiodiversity conservation. Thus, less vulnerable and more resilient smallholder farming systems constitute an important requisite for sustainable land management and to safeguard the livelihoods of millions of rural and urban households. This study compares a comprehensive socioeconomic and environmental dataset collected in 2015–2016 based on household interviews of 30 farmers of highland agroforestry systems and 30 farmers of conventional agriculture systems, to determine which system provides better opportunities to reduce exposure and sensitivity. A modified Climate Change Questionnaire Version 2 of the World Overview of Conservation Approaches and Technologies (WOCAT) was applied to collect the data. The interview data are based on the perceptions of Kayambi indigenous farmers about the levels of exposure and sensitivity of their farming systems during the last decade. Descriptive statistics were applied to analyze the data from the 60 farms. Results indicate that both agroforesters and conventional farmers clearly perceived increases in temperature and reductions in precipitation for the last decade, and expected this trend to continue in the next decade. Furthermore, conventional farmers perceived greater exposure to droughts (20%), solar radiation (43%), and pests, weeds and disease outbreaks (40%) than agroforesters. Additionally, results emphasize the better ability of agroforestry systems to reduce exposure and sensitivity to climate change and variability. These findings support the well-known assumptions about the key role played by agroforestry systems for climate change adaptation and mitigation, especially in developing countries.

<div><p>ABSTRAK</p><p>Keterbatasan lahan pertanian mendorong masyarakat/ petani membuka lahan baru di kawasan hutan, dengan cara menebang dan membongkar tanaman hutan serta membakar sisa-sisa tanaman dan semak belukar, akibatnya lahan menjadi kritis. Salah satu upaya untuk mengatasi masalah tersebut adalah melalui penerapan sistem agroforestri berbasis kopi. Agroforestri berbasis kopi yang sudah dikembangkan petani berperan dalam : (1) Konservasi lahan, air dan keanekaragaman hayati, (2) Penambahan unsur hara lahan, (3) Pengendalian iklim mikro, (4) Penambahan cadangan karbon (5) Menekan serangan hama dan penyakit dan (6) Peningkatan pendapatan petani. Agroforestri berbasis kopi telah dipraktekkan oleh petani pada berbagai wilayah di Indonesia, diantaranya di Lampung Barat (pola hutan kemasyarakatan dan hutan desa), Jawa Barat dan Jawa Tengah (pola pengelolaan hutan bersama masyarakat). Tantangan/masalah yang dijumpai pada agroforestri berbasis kopi diantaranya (1) Tingkat pengetahun petani tentang budidaya agroforestri berbasis kopi yang masih rendah, (2) Terbatasnya modal usaha dan (3) Ketidakpastian status lahan usaha. Upaya untuk mengatasi masalah tersebut dapat dilalukan melalui pelatihan dan pendampingan teknologi budidaya, bantuan modal usaha dan kepastian hukum status lahan. Pengembangan agroforesti berbasis kopi diarahkan pada dikawasan hutan milik Perum Perhutani, hutan kemasyarakan (HKm) dan hutan desa (HD) yang luasnya masing-masing 2.250.172; 2.500.000 dan 500.000 ha.

Modifikasi pemanfaatan lahan memiliki dampak baik ekonomi maupun ekologi. Perlindungan terhadap keanekaragaman hayati menjadi pusat perhatian dari sisi ekologi sementara pemanfaatan lahan demi produktivitas dianggap sebagai solusi ketahanan pangan. Serangga berada di dua isu tersebut yaitu konservasi dan ketahanan pangan. Penelitian ini bertujuan untuk mengetahui struktur komunitas serangga berdasarkan pada peran mereka dalam tingkatan trofik pada tiga tingkat perkembangan agroforestri (AF) jati yang berbeda (awal, tengah, lanjut). Pengambilan data dilakukan di Nglanggeran, Gunungkidul, Yogyakarta sepanjang musim kemarau (April, Mei, dan Juni 2016). Metode koleksi serangga yang digunakan adalah sweep net, pitfall dan sticky trap yang ditempatkan pada petak ukur (PU) 20 x 20 m2. Petak ukur dibuat dan diletakkan secara purposive pada masing-masing tingkatan AF. Total terdapat 8 PU yang terdiri dari 3 PU untuk tingkatan AF awal dan tengah, serta 2 PU untuk AF lanjut. Serangga yang tertangkap bervariasi berdasar pada tingkat perkembangan agroforestri dan bulan pengamatan. Terdapat perbedaan keragaman serangga (jumlah dan jenis) berdasarkan perbedaan tingkatan agroforestri (awal, tengah, dan lanjut) pada lahan lahan agroforestri berbasis jati di Desa Nglanggeran, Zona Batur Agung, Gunungkidul. Agroforestri awal dan tengah menunjukkan kemelimpahan serangga (ordo) terbanyak dengan proporsi tertinggi serangga yang berperan sebagai hama berasal dari ordo Lepidoptera, Diptera, Blattaria, Hymenoptera, Orthoptera, Coleoptera, Isoptera, dan Dermaptera. Tingkatan AF berpengaruh terhadap kehadiran serangga dari ordo Hymenoptera dan Diptera, lebih lanjut keragaman vegetasi pada agroforestri (awal dan tengah) dapat meningkatkan keragaman serangga baik yang berperan sebagai hama (trofik 2) maupun musuh alami (trofik 3).Kata kunci: agroforestri; hama; jati; serangga; trofik Insect Abundance and Its Structure Trophic Level on Different Level of Teak-Based Agroforestry Development at Nglanggeran Village, Gunungkidul District, YogyakartaAbstractModifications of land use have the economic and ecological implications. Protection upon biodiversity has been the center of concern on ecological side, while productivity of the land use has been considered a solution for food security. Insects are between these two major issues, namely conservation and food security.This study was aimed at tracing the structure of insect community based on its role on the trophic level on three different phases of teak-based agroforestry systems (early, middle, and advanced). The data was obtained in the area of Nglanggeran, Gunungkidul Regency of Yogyakarta during the dry season (April, May, and June 2016). Further, method of insect sample inventory utilized sweep net, pitfall trap, and sticky trap placed on measured area of 20 x 20 m2. The plots were placed purposively on each of agroforestry land, with the total of 8 plots, consisting of 3 areas of early and middle levels of agroforestry land, and 2 for late phase. Catched insects varied according to agroforestry growth and observation time. This research suggests that insect’s variety (abundance and morphospecies) is found based on agroforestry levels (early phase, middle phase and late phase) on observed teak agroforestry land in Nglanggeran Village of Batur Agung Zone, Gunungkidul. Early and middle agroforestry showed an abundance of insects (order), in which the largest proportion of them is categorized as pest (Lepidoptera, Diptera, Blattaria, Hymenoptera, Orthoptera, Coleoptera, Isoptera, and Dermaptera). The growth level of agroforestry has a direct impact on the presence of insects of Hymenoptera and Diptera orders. Furthermore, the variety of vegetation in early and middle agroforestry could increase the variety of insects functioning as either pest (trophic 2) or natural predators (trophic 3).

Farmer often undergo of constraint in determining optimal price so that the farmer often undergo of loss, it is because the price of the commodity sold is less than the cost of production in the management of agroforestry systems. Determination Optimalization price of commodity agroforestry expected able to improve income of farmer agroforestry maximally. Objectives of this Research is to analyze the optimization of agrocommodity prices to increase farmers' income. This research used Rudihilmanto Pricing method. Result of this research points out proportion plants: coffee (98.30%), clove (0.45%), melinjo (0.23%), and petai (1.02%) in farmers' fields have optimal price ≥ real price so that this condition has risks and disadvantages for farmers now, but if the proportion is changed as coffee (31.77%), clove (28.79%), melinjo (19.06%), petai (20.37%), therefore optimal price is lower than the real price and it is possible to provide the maximum gain to the farmers of Rp.122,056,970.00 per annum in one hectare. Petani sering mengalami kendala dalam menentukan harga optimal sehingga petani sering mengalami kerugian, hal ini karena harga komoditi yang dipasarkan lebih kecil daripada biaya produksi dalam pengelolaan sistem agroforestri. Penentuan optimalisasi harga pada komoditi agroforestri diharapkan mampu meningkatkan pendapatan petani pengelola agroforestri secara maksimal. Tujuan penelitian ini adalah untuk menganalisis optimalisasi harga komoditi agroforestri untuk meningkatkan pendapatan petani. Penelitian ini menggunakan metode Harga Rudihilmanto. Hasil penelitian menunjukkan proporsi tanaman kopi (98,30%), cengkeh (0,45%), melinjo (0,23%), dan petai (1,02%) di lahan petani memiliki harga optimal ≥ harga riil sehingga kondisi ini memiliki risiko dan kerugian bagi petani, tetapi apabila proporsi diubah menjadi tanaman kopi (31,77%), cengkeh (28,79%), melinjo (19,06%), petai (20,37%) maka harga optimal ≤ harga riil dan dimungkinkan mampu memberikan keuntungan yang maksimal bagi petani sebesar Rp.122.056.970,00 tiap tahun dalam satu hektar.

Coffee agroforestry systems have great potential in optimizing the dual function of carbon and biodiversity conservation, especially in areas with high land use pressure. However, although coffee agroforestry has been widely practiced in Indonesia, the specific relationship pattern between carbon stocks and vegetation biodiversity is still not well understood. This study aimed to evaluate (1) the role of coffee agroforestry in maintaining vegetation diversity and carbon sequestration compared to disturbed forests (HT) and (2) the relationship between carbon stocks and biodiversity at various plant growth stages. Three land use systems were selected such as HT and complex (AFM) and simple (AFS) coffee-based agroforestry systems. The number of trees, species richness (R), Shannon-wiener index (H’), species evenness (E), and carbon stocks were measured in 12 plots (100 m x 20 m) for each vegetation growth stages (seedlings, saplings, poles, and trees). The results showed that the H index in coffee agroforestry was generally low to moderate (0.57-2.05), with the highest diversity in the tree category. The diversity level of AFM could mimic HT. In terms of carbon stock, HT had the highest stock (82±19 Mg ha-1), while total carbon stock showed a positive relationship with H index in all vegetation stages (R2=0,13-0,57). In contrast, the relationship between soil carbon stock and H index tended to be weak (R2=0,10). This study emphasizes the importance of maintaining total carbon stock through diverse vegetation in agroforestri systems to support climate change mitigation and biodiversity conservation.

Les systèmes agroforestiers contribuent comme les forêts à la conservation physique et chimique du sol, à la régulation thermique et à la conservation de la biodiversité. Cette étude visait à caractériser la communauté des espèces ligneuses alimentaires dans quatre systèmes agroforestiers périphériques au noyau central de la Forêt Classée de la Lama. Au total, 770 placeaux carrés (30 m x 30 m) ont été installés de façon aléatoire dans les champs, plantations privées, jardins de case et jachères. Dans chaque placeau, des mesures dendrométriques (diamètre) ont été effectuées sur les individus de diamètre ≥ 5 cm à 1,30 m du sol. L’indice de similarité de Jaccard et le diagramme de Venn ont permis d’évaluer la similarité entre les systèmes agroforestiers. La valeur la plus élevée de l’indice de Shannon a été enregistrée dans les jachères. La structure en diamètre des ligneux présentait une prédominance des sujets de petit diamètre [5-25 cm [. Les jardins de case étaient les seuls regroupant des individus de petites tailles. Une faible variation floristique a été observée entre les systèmes. Il devient impérieux d’intervenir afin d’assurer la conservation de ces espèces.
English title: Diversity and conservation status of woody food species at the periphery of the Lama forest reserve (Benin)
Agroforestry systems, like forests, contribute to the physical and chemical conservation of the soil, to thermal regulation and to the biodiversity conservation. The study aimed to characterize the community of edible woody species in four agroforestry surrounding the central core of the Lama Forest Reserve. A total of 770 square plots (30m x 30m) were randomly installed in fields, private plantations, home gardens and fallows. In each plot, dendrometric measurements (diameter) were taken on individuals with a diameter ≥ 5 cm at 1.30 m from the ground. Jaccard similarity index and Venn diagram were used to assess the similarity between agroforestry systems. Species density varied significantly from fields to home gardens. The diameter structure of the woody plants showed a predominance of small diameter individuals [5-35 cm [. The home gardens were the only ones gathering individuals of small sizes. A low floristic variation was observed between the systems. It becomes imperative to intervene to ensure the conservation of these species.

Shott) under three species stands using agroforestry system in community forest siteAbstractTaro (Colocasia esculenta L. Shott ) is a functional food plant. Based on Permenhut P.35/2007 with regard to Non Wood Forest Product, taro is categorized as a starch plant. According to the knowledge of local people, the agroforestry of taro has been applied on dry land of private forest. The objective of this research was to evaluate the growth and productivity of taro under three tree species of the private forest using agroforestry system. Survey and field observation were conducted in this research. Agroforestry systems were observed on sengon+taro, jabon+taro, manglid+taro, and monoculture of taro as a control. Growth and production of taro plants were measured, including height growth, number of leaves, wet and dry weight of leaves and stems. Wet and dry weight of tuber were recorded to calculate the taro production. Tree species showed significant effects on growth and production of taro plant in agroforestry system. The highest biomass of taro (366.57 g/plant) was found under jabon species, followed by sengon (266.15 g/plant), manglid (175.64 g/plant), and taro monoculture (182.98 g/plant), respectively. The light intensity under jabon tree in agroforestry system was 41.17%. The highest production of wet and dry weight of taro tuber were 2,333.0 g/plant and 884.3 g/plant, which was resulted under jabon stands, followed by under sengon stands (1,597.0 g/plant and 535.7 g/plant), under manglid stands (607.6 g/plant and 213.6 g/plant) and monoculture (739.4 g/plant and 256.3 g/plant), respectively.

Climate-Smart Agriculture (CSA) is increasingly being promoted by the international community to help farmers adapt to climate change and lift them out of poverty. An essential technique that is promoted under the climate- mitigating smart agriculture policy package to reduce forest loss is agroforestry—the planting of woody plants or trees into farming systems. Integrating agroforesty into cocoa landscapes, it is argued, create forest-like habitats which serves as faunal refuges, sequester carbon and therefore contribute to increasing agricultural productivity, resilience (adaptation) and removal of greenhouse gas emissions. This article uses a qualitative data collected from 100 households in seven communities around the Kakum National Park in the Twifo Hemang Lower Denkyira District in Ghana, where a climate-smart agriculture programme is being piloted. The study analysed the extent of willingness of farmers to participate in interventions that promote increased adoption of agroforestry in cocoa landscapes. The result shows that though farmers have favourable perception about the role of agroforestry on cocoa systems, and are willing to adopt the practice, this does not automatically translate into their willingness to participate in agroforestry program that was asking them to extend the number of trees currently maintained on their cocoa landscapes. The study further reveals that size of farms, the age and height of cocoa trees, extension support and the general ecology of the cocoa varieties as some of the reasons influencing whether the agroforestry practices promoted could be adopted or not.

Agroforestry as active area of multi-, inter-, and transdisciplinary research aims to bridge several artificial divides that have respectable historical roots but hinder progress toward sustainable development goals. These include: (1) The segregation of “forestry trees” and “agricultural crops”, ignoring the continuity in functional properties and functions; the farm-scale “Agroforestry-1” concept seeks to reconnect perennial and annual, woody and nonwoody plants across the forest–agriculture divide to markets for inputs and outputs. (2) The identification of agriculture with provisioning services and the assumed monopoly of forests on other ecosystem services (including hydrology, carbon storage, biodiversity conservation) in the landscape, challenged by the opportunity of “integrated” solutions at landscape scale as the “Agroforestry-2” concept explores. (3) The gaps among local knowledge of farmers/agroforesters as landscape managers, the contributions of social and ecological sciences, the path-dependency of forestry, environmental or agricultural institutions, and emerging policy responses to “issue attention cycles” in the public debate, as is the focus of the “Agroforestry-3” concept. Progress in understanding social–ecological–economic systems at the practitioners–science–policy interface requires that both instrumental and relational values of nature are appreciated, as they complement critical steps in progressing issue cycles at the three scales. A set of hypotheses can guide further research.

AbstractFour land use options—annual cropping, agroforestry, agrihorticulture, and agrosilviculture—were tried on a Land Capability Class IVs Alfisol under rainfed conditions to find a farming system that would be profitable and sustainable. The agrihorticultural system required more cash input but gave a value/cost ratio of 2.16 compared with 1.95 with annual cropping, 1.69 with agroforestry and 1.52 with agrosilviculture. Runoff was 4.9% in the agrihorticultural system, and 10.6% with agroforesty. Economic and soil health considerations led to the conclusion that the agrihorticultural system would be a sustainable land use option for the semi-arid Alfisol However, other options also are profitable, with value/cost ratios of more than 1.50. Therefore, land users can choose among several systems, depending on their desired production level and their investment capacity.

The agroforestry system is a technique of use and land management developed through the development of science and technology. One of the agroforestry systems that is implementing in the province of South Kalimantan is in the Paramasan Bawah Village, Banjar Resident. The combination of agroforestry patterns implemented in the Paramasan Bawah Village is forestry with agricultural plants of Sengon and sacred PB rice. The red rice PB was the superior rice in Paramasan Bawah Village because it has a history of the village’s customs. The challenges facing society have been unable to develop widely because of inadequate human resource capability factors and a lack of regular market share. One of the efforts to developing sacred red rice PB collaborates with government agencies and village institutions that form. The data SWOT analysis shows it to quadrant 1, which means that research is in good condition because it supports a power factor to seize a profitable opportunity. The PB sacred red rice strategy through agroforestry patterns can minimize weaknesses to solve problems that would pose a threat to development.Sistem agroforestri merupakan teknik pemanfaatan dan pengelolaan lahan yang di kembangkan melalui perkembangan ilmu dan teknologi. Salah satu sistem agroforestri yang di terapkan di Provinsi Kalimantan Selatan berada di Desa Paramasan Bawah Kabupaten Banjar. Kombinasi pola agrofestri yang di terapkan di Desa Paramasan Bawah adalah tanaman kehutanan dengan tanaman pertanian berupa tanaman sengon dan beras merah “Keramat PB”. Beras merah “Keramat PB” merupakan beras unggulan di Desa Paramasan Bawah karena memiliki sejarah dari adat desa tersebut. Kendala yang di hadapi selama ini masyarakat tidak dapat mengembangkan secara luas karena faktor kemampuan Sumber Daya Manusia (SDM) yang kurang memadai dan belum adanya pangsa pasar yang tetap. Salah satu upaya untuk mengembangkan beras merah “Keramat PB” bekerjasama dengan instansi pemerintah dan lembaga desa yang terbentuk, berdasarkan data hasil analisis SWOT menunjukkan pada kuadran I yang berarti bahwa hasil penelitian termasuk pada situasi yang sangat baik karena didukung dari faktor kekuatan untuk meraih peluang yang akan menguntungkan. Strategi Pengembangan Beras Merah “Keramat PB” melalui pola agroforestri dapat meminimalisir kelemahan untuk mengatasi berbagai masalah yang akan menjadi ancaman pengembangan.

Aonla based multistoried agroforestry with vegetables is a promising solution to mitigate the devastating effects of climate change by offering multidimensional benefits. Disappointedly, Bangladeshi farmers are less equipped about the cultivation techniques, economics, and yields of multistory agroforestry production systems. Consequently, the goal of the current study was to evaluate the profitability and yield potentiality of aonla-based multistoried broccoli production system during the period of November 22 to March 23. Three separate multistory agroforestry systems were covered by the three treatments, while an open field served as the control treatment. to keep track of the system's expansion and economic success; soil analysis, photosynthetically active radiation, plant height, number of leaves, head length, head width, head weight, total yield, BCR, and LER were calculated following different established methods. While compared to sole cropping, the agroforestry approach drastically reduced the production of broccoli by 89%. Soil organic matter, nitrogen, phosphorous, potassium, and sulfur were higher in agroforestry system than that of control plot. In fact, the agroforestry system had some negative effects on the rate of crop growth in understored conditions. Despite, net return and BCR from aonla-based multistoried agroforestry system were 4-11 lakh and 2.24-3.98, which was 69-87 and 41- 67 %, respectively higher than sole cropping systems. The LER of aonla based multistoried agroforestry system was 3.20. The major conclusions show that aonla orchards can be converted to agroforestry systems to increase productivity, generate money, and protect the environment, however due to poor performance, broccoli cannot be grown in multistory systems.

Of late, the importance of agroforestry is increasingly being realized from all corners owing to its multifaceted role in sustainable production, soil health, biodiversity conservation, employment generation, drought proofing, natural resource conservation and ecosystem services. Agroforestry is a unified land-use system involving all dis- ciplines. Though the basic principles of agronomy remain the same, the agronomic practices, are slightly modified owing to presence of perennial component in agroforestry. This paper provides a brief review of all aspects of ag- ronomic practices under agroforestry, so as to give some insights to researchers, teachers, students, farmers and planners. The issues like agroforestry situation in India; selection of agroforestry components and their establish- ment; management of water, nutrients, weeds and insect-pests and diseases; environmental services and natural resource conservation are highlighted here.

Testo completoAbstract (sommario):
Agroforestry can provide ecosystem services and benefits such as soil erosion control, microclimate modification for yield enhancement, economic diversification, livestock production and well-being, and water quality protection. Through increased structural and functional diversity in agricultural landscapes, agroforestry practices can also affect ecosystem services provided by insect pollinators. A literature review was conducted to synthesize information on how temperate agroforestry systems influence insect pollinators and their pollination services with particular focus on the role of trees and shrubs. Our review indicates that agroforestry practices can provide three overarching benefits for pollinators: (1) providing habitat including foraging resources and nesting or egg-laying sites, (2) enhancing site and landscape connectivity, and (3) mitigating pesticide exposure. In some cases, agroforestry practices may contribute to unintended consequences such as becoming a sink for pollinators, where they may have increased exposure to pesticide residue that can accumulate in agroforestry practices. Although there is some scientific evidence suggesting that agroforestry practices can enhance crop pollination and yield, more research needs to be conducted on a variety of crops to verify this ecosystem service. Through a more comprehensive understanding of the effects of agroforestry practices on pollinators and their key services, we can better design agroforestry systems to provide these benefits in addition to other desired ecosystem services.

Abstract Agroforestry has long been touted as a management approach with potential for gaining synergies between agricultural and forest production. A staple approach in developing-country situations, agroforestry systems are increasingly being considered in developed-country settings. However, socioeconomic analyses of agroforestry systems have long lagged behind natural science contributions. This volume, the second in the series “Advances in Agroforestry,” makes a significant step in promoting the social science importance of agroforestry. The editors have assembled a nice collection of studies regarding the valuation of agroforestry systems around the world, encompassing developing and developed country settings. The approaches used arise largely from an economics disciplinary background, but there is much in here of interest to a broader, multidisciplinary audience.

Objectif : L’agroforesterie avec l’anacardier prend de l’importance dans les systèmes de productions agricoles au Burkina Faso. Afin de formuler des recommandations aux producteurs pour accroitre la productivité de ces systèmes, l’effet de l’application de quelques bonnes pratiques de production sur le rendement des anacardiers de différents âges a été évalué. Méthodologie et résultats : La répartition des différents âges des anacardiers, les bonnes pratiques de productions appliquées et le rendement de l’anacardier sont les données collectées à travers des focus group avec les coopératives de producteurs d’anacarde et des entretiens individuels avec des producteurs dans quatre (04) communes de la région des hauts bassins. Les anacardiers en agroforesterie sont vieillissants mais leurs rendements semblent être maintenus grâce à l’application des bonnes pratiques de production incluant l’application des pratiques sylvicoles, l’utilisation de la fumure organique et l’utilisation des plants produits en pépinière ou des semences de qualité. Les anacardiers en agroforesterie les plus âgés (plus de 25 ans) ont eu les rendements les plus importants du fait d’une meilleure application de ces bonnes pratiques de production. Conclusion et application des résultats : Un des facteurs importants qui semble influencer la production de l’anacardier est une bonne application des bonnes pratiques de production et non l’âge des anacardiers. Il est donc important de renforcer les capacités des producteurs sur ces bonnes pratiques de production et de les recommander une application accrue de celles-ci. Des expérimentations de terrain pour évaluer les effets de l’application de quelques bonnes pratiques sylvicoles et de l’utilisation de la fumure organique sur différents âges des anacardiers de même provenance en agroforesterie sont requises et permettront d’avoir des informations complémentaires aux résultats de cette recherche. Mots clés : revenus, anacardier, hauts bassins, rendement Effects of good production practices on different âges of Anacardium occidentale L. based agroforestry in Burkina Faso (West Africa) ABSTRACT Objective : Cashew-based agroforestry is taking importance in Burkina Faso agricultural production systems. In order to formulate recommendations to farmers for increasing cashew trees productivity in these systems, this research evaluated the effects of applying some good production practices on cashew trees yields of different âges. Methodology and results : Data related to the distribution of different cashew trees âges, the good production practices applied and the cashew trees yields were collected through focus group discussion with the cooperatives of farmers and individual interviews with farmers in four (04) communes at the hauts bassins region. Cashew trees in agroforestry are becoming old but their yields seem to be maintained through the application of good production practices including the application of sylvicultural practices, the use of organic manure and the use of plants produced in nursery or seeds of quality. The oldest cashew trees (more than 25 years old) in agroforestry had the highest yields due to a better application of these good production practices. Conclusion and application of results : One of the major factors which seem to influence cashew production is the better application of good production practices and not the âge of cashew trees. It is therefore important to strengthen farmers capacities on good production practices such as the sylvicultural practices, the use of organic manure and the use of plants produced in nursery or seeds of quality and to recommend farmers their further application. Fields experiments to test the effects of applying some sylvicultural practices and the application of organic manure on cashew trees of different âges from the same provenance are required to have additionnal informations to the results of this research.

Agroforestry systems and practices are perceived to improve livelihood and sustainable management of natural resources. However, factors influencing their adoption in various regions require further investigation as they differ in biophysical conditions and societal characteristics. This study was conducted in Kilombero district to investigate factors influencing the adoption of different agroforestry systems and practices in agro-ecosystems and farming systems. Household surveys, key informant interviews and focus group discussions were used in data collection. Descriptive statistics and Multinomial Regression Analysis in SPSS were used for data analysis. Results show that Agrosilvopasture and Agrosilviculture systems were the dominant agroforestry systems while the home garden and Mixed Intercropping were the dominant agroforestry practice. There is a potential in agroforestry systems and practices in terms of product diversification and biodiversity conservation though their adoption differed given the influence of different factors. Different factors were statistically significant as predictors of the adoption of agroforestry systems and practices. Residence period, availability of extension education/services, residence type and gender were the dominant factors influencing the adoption of agroforestry systems and practices. Farmers' oriented factors were critical in the adoption of agroforestry systems and practices. The study concludes that the practice of agroforestry will be more successful if the local priorities including socio-economic characteristics of the society are considered in designing systems and practices. Socio-economic characteristics of the communities that factor in conservation priorities should be addressed in the process of expanding the adoption of agroforestry systems and practices. Study recommends that productive systems and practices that contribute to household food and income are better adopted.

This paper explores the status of agroforestry systems and practices in the Terai and hill regions of Nepal. Field survey, semi-structured interview and focus group discussions with the local farmers and stakeholders were conducted to explore the status of the agroforestry system and practices. The study covers forty-three districts, and represents agroforestry systems and practices in the Terai and hill regions of Nepal. Altogether, twelve agroforestry systems and forty-three agroforestry practices were documented in the Terai and hills of Nepal- ten systems in the Terai and seven systems in the hills. Agrisilviculture, agrisilvihorticulture, agrosilvopastoral, agrohortosilvopastoral, homegarden, hortiagriculture, silvofishery, agrosilvifishery, hortisilviculture and apiculture were the major agroforestry systems adopted in the Terai whereas those adopted in the hills included hortiagriculture, agrisilviculture, agrisilvihorticulture, agrosilvopastoral, homegarden, hortosilvipastoral and silvopastoral. The study revealed a gradual emerging scenario of commercial agroforestry systems in these regions although the continuation of traditional agroforestry systems was observed in most of the Terai and hill regions. Insufficient labour availability, fragmentation of land, market price fluctuation, lack of technical knowledge, and wild animal disturbances were some of the major challenges observed in the Terai and hills of Nepal.

Man and ecosystems are highly threatened by the abusive application of chemical fertilizers in a bid to enhance soil fertility and improve crop productivity. These chemical fertilizers pose serious health risks to farmers and the population at large and contribute to short and long-term soil degradation. Thus, this study was initiated to examine how agroforestry can contribute towards phasing out chemical fertilizers application in smallholder farms in the south west region of Cameroon. Data collection was done from secondary and primary sources and analyzed using inferential and descriptive statistics. Microsoft Excel 2013 and SPSS version 17 were used to run the descriptive and inferential statistics. It was found that silvopastoral, agrosilvopastoral and agrosilvicultural systems were the most dominant agroforestry systems, with different agroforestry practices like coffee-based agroforestry plantations, cut and carry fodder, home gardens, trees/shrubs on farmlands, cocoa-based agroforestry plantations, live fences, improved fallows and home gardens with livestock characterizing these three agroforestry systems. These agroforestry systems provided different ecosystem services to agroforestry practitioners with the most common being food, fuelwood, finance/income, and climate moderation. Besides food and soil fertility enhancement, very limited or no chemical fertilizer was used to obtain the other ecosystem services. There was an inverse relationship (p<0.05) between ecosystem services of agroforestry systems and chemical fertilizer application, demonstrating that chemical fertilizers are not needed to enhance the ecosystem services of agroforestry systems. There was equally an inverse relationship (p<0.05) between agroforestry systems and chemical fertilizer application, indicating that farmers’ practice of agroforestry reduces chemical fertilizer application on farms. Agroforestry is therefore recommended as a sustainable pathway to limit and/or eradicate farmers’ application of chemical fertilizers.

Agroforestry systems may show low CO2 efflux, and CO2 efflux contributes to sustainability. This work aimed to evaluate the soil CO2 efflux in coffee plantations cultivated in agroforestry and full-sun systems during the winter in high-altitude tropical climate regions. The work was carried out at three family farms (RO, GI, and PA) in Minas Gerais, Brazil. Two treatments were established: coffee with and without trees, and 20 sampling spots for soil and gases. The air and soil temperatures in the agroforestry systems were lower than in the full-sun systems. The soil moisture content in agroforestry systems was higher than full-sun only on the GI. Except for the agroforestry systems in PA, all the other systems showed an increase in CO2 efflux with increasing soil moisture. This increase was more pronounced in agroforestry systems (RO), followed by full sun (RO). On the GI farm, this correlation was lower in the agroforestry system. Soil CO2 efflux was positively correlated with soil temperature and negatively correlated with total nitrogen, labile carbon and total organic carbon. Therefore, despite the microclimate stability promoted by the agroforestry systems in the winter, no decrease in the soil CO2 efflux was observed when compared to full sun systems.

Abstract Agroforestry consists of various land covers that produce litter, which results in the addition of organic matter to the soil and improves soil quality. This study aims to determine the status of soil quality in various agroforestry systems by calculating the soil quality index in various agroforestry systems. This research was conducted in Banyurip Village, Jenar District, Sragen Regency, Indonesia. This research was conducted on various agroforestry systems, namely teak agroforestry, teak-sacha inchi agroforestry, and sacha inchi monoculture, as well as land that does not apply agroforestry systems. A total of nine indicators were used, and then the indicators were tested with principal component analysis using Minitab 18 to select the minimum data set. The indicators were chosen as soil humidity, bulk density, porosity, CEC, soil total N, soil organic C, and microbial biomass C. The highest soil quality indexes in teak agroforestry and teak-sacha inchi agroforestry were 0.22. The highest soil quality index in teak agroforestry and teak-sacha inchi agroforestry each was 0.22, and the soil quality index in sacha inchi monocultur was 0.20. The soil quality of the three types of agroforestry is low because the soil quality index ranges from 0.2-0.39.

Agroforestry systems have multifunctional roles in enhancing agronomic productivity, co-production of diversity of food and non-food products and provision of ecosystem services. The knowledge of the performance of agroforestry systems compared with monoculture is scarce and scattered. Hence, the objective of the study was to analyze the agronomic productivity and economic viability of diverse agroforestry systems in Europe. A network of five agroforestry systems integrating arable crops, livestock and biomass trees was investigated to assess the range of agricultural products in each agroforestry system. Land Equivalent Ratio (LER) was used to measure the agronomic productivity, whereas gross margin was used as an indicator for economic viability assessment. LER values ranged from 1.36–2.00, indicating that agroforestry systems were more productive by 36–100% compared to monocultures. Agroforestry gross margin was lower in Denmark (€112 ha−1 year−1) compared to United Kingdom (€5083 ha−1 year−1) and the crop component yielded higher returns compared to negative returns from the tree component in agroforestry. Hence, the study provided robust field-based evidence on agronomic productivity and economic viability assessment of agroforestry systems in diverse contexts for informed decision making by land managers, advisory services, farmers and policymakers.

The control plots (without lemon plant) for each of the five lemon-based agroforestry systems were also selected. In order to calculate the economic profitability of respective agroforestry systems as well as sole cropping performance, data related to incurred cost, total yield and income from lemon and crop components were collected through practical observation, key informant interview and focus group discussion. The benefit-cost ratio (BCR) and land equivalent ratio (LER) for each of the selected agroforestry systems were also determined. From the study, it has been found that all of the lemon-based agroforestry systems were profitable than their sole cropping in respect of income, BCR, and LER. The net profit (460032 Tk/ha) indicated that the Lemon-Litchi-Papaya-Banana based agroforestry systems were financially more profitable followed by Lemon-Pineapple-Papaya-Banana-Aroid, Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth based agroforestry systems. But the BCR and LER (3.515 and 1.73) revealed that Lemon-Pineapple-Papaya-Banana-Aroid based agroforestry system was more productive followed by Lemon-Litchi-Papaya-Banana, Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth based agroforestry systems. Prior to considering the obtained results from the study, it can be concluded that lemon-based agroforestry systems are more profitable than the cultivation of sole cropping.

Agroforestry systems can be considered as sustainability concept. They are able to provide ecological, economical and sociological benefit. In order to help policy makers and stakeholder decide what action should be taken to make agroforestry sustainable, the identification of the sustainability status is needed. This study aimed to evaluate the sustainability status of agroforestry systems in Timor Island, one of the islands in Nusa Tenggara Timur Province, eastern Indonesia. The data was collected through combination of field observation and interviews with 38 respondents with purposively selected in three dominant agroforestry systems, namely: mixed-garden, mamar, traditional agroforestry and silvopasture. Multidimensional Scaling approach was used to analyse the sustainability status of agroforestry systems based on five dimensions (ecology, economy, social, institutional and technology) as well as 26 attributes. The attribute valuation was in ordinal scale based on sustainable criteria of each dimension. The criteria were ranked from 0 (the lowest) to 3 (the highest). The assessment of sustainability status was classified into: not sustainable (0-25%), less sustainable (25-50%), moderate sustainable (50-75%) and good sustainable (75-100%). The result revealed that the sustainability of all agroforestry systems were in moderate sustainable. This study found that, only 15 out of 26 attributes were categorized as sensitive attributes. Such data and information are important for the agroforestry farmer or other related stakeholder for improving appropriate strategies or action in sustainable agroforestry management.

The study was carried out in the Madhupur Sal forest of Bangladesh to perform the productivity analysis of mango-based agroforestry systems. In order to achieve the objective, three different mango-based agroforestry systems along with three control plots having three replications were randomly selected in three sites of the study area. The size of individual study plot was 33 decimals. The selected three mango-based agroforestry systems were viz. i) mango + pineapple+ ginger + papaya + banana + turmeric, ii) mango + pineapple + ginger + papaya + banana, and iii) mango + turmeric+ papaya + aroid based agroforestry systems. In order to calculate the productivity of respective mango-based agroforestry systems as well as sole cropping performance, data related to incurred cost, total yield and income from tree and crop components, soil samples for soil chemical properties changes were collected from each plot that produced BCR and LER. The results revealed that the total calculated cost of production (tk/ha) and total yield (tk/ha) from selected mango-based agroforestry systems were Tk. 202421, 186373 and 163631 along with Tk. 1076344, 956095 and 816520 respectively. The BCR and LER of the selected above mango-based agroforestry systems were 5.32, 5.13, 4.99 and 3.27, 2.76, 2.32 respectively. Therefore, mango-based agroforestry systems are more profitable than sole cropping system.

Many field crop lands are being transformed to fruit orchards in different locations of Bangladesh. There is an ample scope to cultivate intercrops in the orchards following scientific manner and proper technology including suitable varieties. In this study, mango and orange orchards were transformed to agroforestry system in Kotchandpur upazila under Jhenaidah district to investigate the performances of selected vegetable varieties (bottle gourd, stem amaranth, papaya, cauliflower, and country bean) developed by the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU). Randomized complete block design was used to compare agroforestry (mango and orange orchards) and non-agroforestry (open field) treatments for identifying suitable tree-vegetable combinations. The results indicated that yields of the tested vegetables were higher in the non-agroforestry system (crop field without trees) compared to the agroforestry system. Yields of bottle gourd stem amaranth, cauliflower, and country bean in agroforestry systems decreased by 21, 7, 18, and 19%, respectively, compared to non-agroforestry system. On the contrary, yield reductions were 7.9, 15.7, 3.9 and 4.6% in mango-based agroforestry than orange-based agroforestry for bottle gourd, stem amaranth, cauliflower, and country bean, respectively. The findings suggested that although all the tested vegetables can be grown in agroforestry, but creeping type vegetables are less suitable. Despite the observed reduction in yields, the fruit tree-based agroforestry system demonstrated its potential as a viable alternative, offering to reduce crop failure risk to the farmers and optimizing land utilization. The order of the suitability of the tested vegetables are stem amaranth > cauliflower > country bean > bottle gourd in agroforestry systems. Ann. Bangladesh Agric. 27(2):191-199

Chhattisgarh state has very diverse forest ecosystem and long history of traditional agroforestry. An agroforestry practice is location specific and depends on nature of agro-climatic zone. In Chhattisgarh, farmers are doing this farming practices based on fulfilling their diverse need and improvement of socioeconomic condition but stilldata is insufficient to explore more agroforestry practices in the state. In this context, assessment of different agroforestry models gives not only sufficient data but also open a door for conservation of biological diversity.. Different models like’s Boundary plantations, Agri-silviculture system, Horti-silvicuture, Silvi-pasture, Kitchen garden and Block plantation are used by farmers in Dhamtari. All models are dependent on location characteristic, land use type, soil type, climate and market requirement. This paper highlights the different models of Agroforestry, specific model for the specific sites, lacuna in models faced by farmers and role of agroforestry models in socioeconomic upliftment.

The farming systems in Konaweha watershed are mostly mixed garden that are partly managed intensively as wellas traditionally. The objectives of this research were to identify and classify agroforestry systems that were practicedby farmers, to study the effect of the agroforestry systems on soil properties, hydrological indicators, and erosion,as well as to analyze farm management feasibility of agroforestry systems to establish sustainable agriculturesystem. The study was carried out in Konaweha watershed, Southeast Sulawesi. The results indicated thatagroforestry systems in this area were devided into four types i.e. sylvopastoral-perennial crops with pasture,agrosylvicultural-perennial crops, agrosylvicultural-multystrata systems, and sylvopastoral-multystrata systems.The four types of agroforestry systems significantly increased the soil aggregate stability, soil porosity at 30 cm indepth, organic matter, soil organic carbon, and microorganisms population. In addition, the agroforestry haddecreased runoff and erosion significantly. Therefore, the erosion rate from the four types of agroforestry systemwas below the value of tolerated soil loss (TSL), except that of agrosylvicultural-perennial crops with an elevationof > 30%. The best quality of soil and environment was found at sylvopastoral-multystrata systems.Keywords: Agroforestry; erosion; soil properties; sustainable agriculture[How to Cite: Marwah S. 2012.

Purpose. The study aims to (i) discover the various trees and shrubs appropriate for building agroforestry systems in Bulgaria’s temperate climate and their possible use in various economic activities, (ii) identify the contribution of Bulgarians’ agroforestry systems to the three dimensions of sustainable development.
Results. The contributions of Bulgarians’ agroforestry systems to three pillars of sustainability were pointed out. Regarding the social dimension of sustainability, the respondents highlighted the social benefits of agroforestry (e.g., raising the standard of living and the social status of the population; providing jobs and access to renewable energy; overcoming social inequality in individual regions; providing recreation opportunities for the population; give social, educational, scientific, landscape and recreational benefits to society; generate firewood for society). The contribution of agroforestry in the environmental dimension is unquestionable. Moreover, 46 trees and 15 shrubs have been presented. The use of their products in various economic activities and industries has been discussed. These trees and shrubs are appropriate for the construction of various agroforestry systems such as forest-farming, alley-cropping, and forest-pasture agroforestry systems.
Scientific novelty. A few scientific researches focus on tree species suitable for agroforestry systems in particular counties with different climates. However, there is limited research on various trees and shrubs suitable for constructing agroforestry systems in a temperate climate, especially in Bulgaria. Moreover, the use of the products of these trees and shrubs in various economic sectors and activities, which can bring additional economic value for agroforestry farmers in temperate climates, is not discussed in one paper.
Practical value. The current findings will provide farmers with additional knowledge about trees and shrubs suitable for the construction of agroforestry systems in temperate climates and the possible implementation of their products in various economic activities and industries. This will encourage them to create ecoefficient agroforestry systems using some of the 46 trees and 15 shrubs, based on their regional location and local conditions, to support sustainable development and the environment. What is more, if these tree species are promoted by decision-makers and professional/farmer associations, and adopted by the farmers can support and reinforce agroforestry in Bulgaria and regions with temperate climates.

Agroforestry systems have been used from a long time ago. The traditional agroforestry concept and knowledge of integration of the trees in the farm have been passed from one generation to another, especially in the South Asian countries. The study is aimed at collecting information on agroforestry practices prevailing in SAARC countries. Information related to prevailing practices of agroforestry was collected from reviewing literature for each country differently. In Afghanistan, the Government has given the seedlings of trees to grow along with the agricultural land. Multistoried agroforestry system with integration of other plants in different spatial designs is mostly used in Bangladesh. Shifting cultivation is the traditional system, integration of crop production, grazing animals, and forest areas in Bhutan is practiced. Being the first and second country to formulate the Agroforestry policy, both India and Nepal respectively follows a traditional system along with some research-based agroforestry system. Pakistan mostly used the farm-based agroforestry system while in Maldives and Srilanka, Coconut based agroforestry system is used mostly. The communities of the SAARC countries have improved livelihood through the generation of the multi-product through the introduction of the new agroforestry systems. The different systems applied in the SAARC countries should be explored and the issues need to be resolved by the formulation of the policies, conduct research, extensions, and training related to the advancement of the Agroforestry. The knowledge and concept of the different agroforestry systems should be disseminated and other systems should be developed from the consultation with the farmers.

Background Tree-based intercropping (agroforestry) has been advocated to reduce adverse environmental impacts of conventional arable cropping. Modern agroforestry systems in the temperate zone are alley-cropping systems that combine rows of fast-growing trees with rows of arable crops. Soil microbial communities in these systems have been investigated intensively; however, molecular studies with high taxonomical resolution are scarce. Methods Here, we assessed the effect of temperate agroforestry on the abundance, diversity and composition of soil bacterial communities at three paired poplar-based alley cropping and conventional monoculture cropland systems using real-time PCR and Illumina sequencing of bacterial 16S rRNA genes. Two of the three systems grew summer barley (Hordeum vulgare); one system grew maize (Zea mays) in the sampling year. To capture the spatial heterogeneity induced by the tree rows, soil samples in the agroforestry systems were collected along transects spanning from the centre of the tree rows to the centre of the agroforestry crop rows. Results Tree rows of temperate agroforestry systems increased the abundance of soil bacteria while their alpha diversity remained largely unaffected. The composition of the bacterial communities in tree rows differed from those in arable land (crop rows of the agroforestry systems and conventional monoculture croplands). Several bacterial groups in soil showed strong association with either tree rows or arable land, revealing that the introduction of trees into arable land through agroforestry is accompanied by the introduction of a tree row-associated microbiome. Conclusion The presence of tree row-associated bacteria in agroforestry increases the overall microbial diversity of the system. We speculate that the increase in biodiversity is accompanied by functional diversification. Differences in plant-derived nutrients (root exudates and tree litter) and management practices (fertilization and tillage) likely account for the differences between bacterial communities of tree rows and arable land in agroforestry systems.

Agroforestry integrates woody perennials with arable crops, livestock, or fodder in the same piece of land, promoting the more efficient utilization of resources as compared to monocropping via the structural and functional diversification of components. This integration of trees provides various soil-related ecological services such as fertility enhancements and improvements in soil physical, biological, and chemical properties, along with food, wood, and fodder. By providing a particular habitat, refugia for epigenic organisms, microclimate heterogeneity, buffering action, soil moisture, and humidity, agroforestry can enhance biodiversity more than monocropping. Various studies confirmed the internal restoration potential of agroforestry. Agroforestry reduces runoff, intercepts rainfall, and binds soil particles together, helping in erosion control. This trade-off between various non-cash ecological services and crop production is not a serious constraint in the integration of trees on the farmland and also provides other important co-benefits for practitioners. Tree-based systems increase livelihoods, yields, and resilience in agriculture, thereby ensuring nutrition and food security. Agroforestry can be a cost-effective and climate-smart farming practice, which will help to cope with the climate-related extremities of dryland areas cultivated by smallholders through diversifying food, improving and protecting soil, and reducing wind erosion. This review highlighted the role of agroforestry in soil improvements, microclimate amelioration, and improvements in productivity through agroforestry, particularly in semi-arid and degraded areas under careful consideration of management practices.

Agroforestry, the integration of trees, crops, and livestock on the same land, offers a sustainable approach to enhancing agricultural productivity while mitigating environmental challenges. This review highlights the important role agroforestry systems play in promoting resilient and productive landscapes, particularly in the face of climate change, land degradation, and biodiversity loss. Agroforestry systems, including alley cropping, silvopasture, and home gardens, provide significant ecological benefits such as carbon sequestration, reduced greenhouse gas emissions, improved soil health, water conservation, and enhanced biodiversity. These systems not only stabilize microclimates and reduce soil erosion but also improve soil fertility and water infiltration, making them vital for climate adaptation. Socio-economically, agroforestry diversifies income sources for smallholder farmers by generating products like timber, fruits, and fodder, while contributing to food security through year-round crop availability and improved nutrition. Despite these benefits, the adoption of agroforestry faces substantial barriers, including socio-cultural resistance, knowledge gaps, inadequate policy support, and limited access to markets and credit. High initial costs, perceived risks, and competition for resources between trees and crops further impede its widespread implementation. Addressing these challenges requires enhancing extension services, policy reforms, financial incentives, and market access to support smallholder farmers. Future directions emphasize integrating agroforestry into national agricultural policies and climate action plans, supported by research on optimizing species selection, pest management, and sustainable resource use. By the synergies between agroforestry, regenerative agriculture, and Sustainable Development Goals, agroforestry presents a viable pathway for transforming agricultural systems into more resilient, productive, and sustainable models. Scaling up agroforestry can help restore degraded lands, sequester carbon, and enhance the livelihoods of rural communities, contributing to global efforts to combat climate change and promote sustainable development.

AbstractAlternating degradation and restoration phases of soil quality, as is common in crop-fallow systems, can be avoided if the restorative elements of trees and forests can be integrated into productive agroforestry systems. However, evidence for the hypothesis of ‘internal restoration’ in agroforestry is patchy and the effectiveness may depend on local context. We investigated to what extent cocoa (Theobroma cacao, L.) agroforestry can recover soil structure and infiltration in comparison to monoculture systems across the Konaweha Watershed, Southeast Sulawesi. We compared soil organic carbon, fine root length and weight, soil aggregate stability, macroporosity and infiltration from three soil layers at five land use systems: i.e. degraded forests, 9–14 years old of complex-cocoa agroforestry, simple-cocoa agroforestry, monoculture cocoa and 1–4 years old annual food crops, all with three replications. In general, roots were concentrated in the upper 40 cm of soil depth, contained of 70% and 86% of total fine root length and weight. Compared to simple agroforestry and cocoa monoculture, complex agroforestry had greater root length and weight in the topsoil, even though it attained only half the values found in degraded forests. Higher root density was positively correlated to soil organic carbon. In upper soil layers, complex agroforestry had slightly higher soil aggregate stability compared to other agricultural systems. However, no significant difference was found in deeper layers. Complex agroforestry had higher soil macroporosity than other agricultural systems, but not sufficient to mimic forests. Degraded forests had two times faster steady-state soil infiltration than agricultural systems tested (13.2 cm h−1 and 6 cm h−1, respectively), relevant during peak rainfall events. Compared to other agricultural systems, complex agroforestry improves soil structure of degraded soil resulting from forest conversion. However, a considerable gap remains with forest soil conditions.

RESUMO Considerada uma das principais doenças do eucalipto, a ferrugem (Austropuccinia psidii) pode ocasionar sérios danos à cultura caso estratégias adequadas de manejo não sejam implantadas. De modo geral tem-se monocultura de eucalipto, com implicações epidemiológicas importantes. O objetivo desse estudo foi comparar o progresso da ferrugem do eucalipto consorciado com diferentes espécies em sistema agroflorestal, sob condições naturais de infecção. O experimento foi composto por três tratamentos (consórcios), dispostos de forma completamente aleatorizada no espaço. Em cada tratamento o eucalipto foi plantado com duas espécies diferentes, a saber: T1 - Cedro Australiano (Toona ciliata) + Eucalipto (Eucalyptus urograndis) + Banana (Musa acuminata); T2 - consórcio Amora (Morus celtidifolia) + Eucalipto + Pupunha (Bactris gasipaes), e T3 - Mogno Africano (Khaya ivorensis) + Eucalipto + Banana. Cada tratamento foi composto por seis repetições, totalizando 18 parcelas de 9m2 cada (2m x 4,5m), dispostos em linhas/aleia. Foram avaliadas altura, diâmetro da planta, incidência e severidade da doença, quinzenalmente. Os dados foram coletados em dois momentos distintos: pré-poda, compreendido de 17/08/2018 à 09/01/2019, e pós-poda, realizado de 17/04/2019 à 13/08/2019. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey (p<0,05). Verificou-se que o eucalipto apresentou maior desenvolvimento (altura e diâmetro) e menor intensidade da doença (incidência e severidade) no tratamento T2. Com base nos resultados, conclui-se que o plantio de eucalipto em consórcio com as espécies Amora + Eucalipto + Pupunha proporcionou menor intensidade da ferrugem e maior desenvolvimento das plantas.
