Hutan rakyat dengan pola tanam agroforestri memiliki pengaruh terhadap aspek ekologi, seperti: udara bersih, erosi terkendali, serapan karbon, pengaturan tata air, penyangga ekosistem, penjaga stabilitas ekologi, dan perlindungan lingkungan. Oleh karena itu, dalam pengelolaan hutan rakyat pola tanam agroforestri masa kini dan masa depan harus dapat memperhatikan kaidah-kaidah lingkungan. Untuk mewujudkan hal tersebut, maka hutan rakyat pola tanam agroforestri harus sehat. Penelitian ini bertujuan untuk mendapatkan nilai status (saat ini) kesehatan hutan rakyat pola tanam agroforestri di wilayah Kabupaten Lampung Timur. Studi kasus analisis kesehatan hutan dilakukan pada klaster-plot Forest Health Monitoring (FHM) hutan rakyat pola tanam agroforestri di Wilayah Kabupaten Lampung Timur. Jumlah klaster-plot FHM yang dibuat sebanyak empat klaster-plot. Parameter indikator kesehatan hutan rakyat pola tanam agroforestri adalah pertumbuhan pohon, kondisi kerusakan pohon, kondisi tajuk, dan kesuburan tanah. Tahapan dari penelitian ini terdiri dari pembuatan plot ukur hutan rakyat pola tanam agroforestri, pengukuran parameter indikator kesehatan hutan rakyat pola tanam agroforestri, pengolahan dan analisis, dan penilaian kesehatan hutan rakyat pola tanam agroforestri. Hasil penelitian menunjukkan bahwa nilai status kondisi kesehatan hutan rakyat pola tanam agroforestri di wilayah Kabupaten Lampung Timur rata-rata dalam kategori bagus. Hal tersebut menunjukkan bahwa hutan rakyat dengan pola tanam agroforestri akan menghasilkan tingkat kesehatan hutan rakyat yang sehat. Dengan demikian, pembangunan hutan rakyat di wilayah Kabupaten Lampung Timur Provinsi Lampung diarahkan dengan pola tanam agroforestri.
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.

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.

One effort to over come the problem is through the implementation of a coffee-based agroforestry systems. Role-based on agroforestry coffee farmers that have been developed, by farmers involve on (1) Conserve land, water and biodiversity, (2) Add of nutrients lands, (3) Control of microclimate, (4) Add of carbon stocks (5) Suppress pests and diseases, and (6) Enhancement to the income of farmers. Coffee-based agroforestry has been practiced by farmers in various regions in Indonesia, including in West Lampung (patterns of community forestry and forest villages), West Java and Central Java (forest management with communities). Challenge/problems encountered in the coffee-based agroforestry include (1) The level of knowledge of farmers on the cultivation of coffee-based agroforestry still low, (2) Lack of venture capital and (3) The uncertainty of the status of business land. Efforts to overcome these problems can through training and mentoring cultivation technology, venture capital assistance and legal certainty of land status. Development direction of coffee-based agroforestry can be done conduct of region-owned Perum Perhutani, community forestry (CF) and village forest (VF) which covers each 2.250.172; 2.500.000 and 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.

Le changement climatique et la variabilité ont des répercussions graves dans le secteur agricole des régions tropicales. Le secteur du café est sensible au changement climatique car il nécessite une température relativement froide et une plus grande durée des pluies. L'adaptation au changement climatique dans l'agroforesterie du café est donc importante pour traiter les impacts, mais il existe des obstacles et des limites. Le but de cette thèse était d'analyser les stratégies d'adaptation au changement climatique au centre du Kenya. Nous avons étudié différentes étapes de l'adaptation qui incluent (1) les connaissances sur le changement climatique et l'adaptation, la motivation à l'adaptation, (2) le choix actuel des stratégies d'adaptation et leurs déterminants, (3) les rôles du système d'innovation et du contexte institutionnel. Cette étude repose sur quatre sources d'information: - (1) groupes de discussion sur des questionnaires pré-définis, (2) enquêtes auprès des ménages, (3) entrevues auprès des intervenants et (4) données climatiques historiques sur le contexte de quatre types de systèmes de productions dans l’agriculture : les cultures vivrières, le café spécialisé, les systèmes diversifiés café-laiterie et les systèmes laitiers spécialisés, dans les zones caféières et vivrières. L'analyse des tendances de Mann-Kendal et l'estimateur de la pente de Sen ont été utilisées pour comparer les connaissances des agriculteurs sur les changements climatiques et l’historique des données climatiques, tandis que le modèle de Heckman a été utilisé pour analyser les stratégies d'adaptation et leurs déterminants. Les résultats soulignent des cohérences entre les connaissances des agriculteurs et l'analyse historique des données pour la température mais des incohérences avec le changement des précipitations. L'analyse de la perception par les agriculteurs révèle que les précipitations diminuent radicalement au fil du temps, alors qu'aucun élément de preuve concernant les précipitations ne permet d'appuyer la perception des agriculteurs. L'incohérence est donc corroborée par l'analyse des modèles. Les agriculteurs du secteur du café et des cultures vivrières se sont adaptés différemment aux changements climatiques. Les agriculteurs qui sont conscients des changements sont plus disposés à explorer les stratégies d'adaptation. Une partie des agriculteurs qui ne perçoivent pas le changement climatique adoptent des stratégies d’adaptation à des facteurs autres. L'adaptation au changement climatique est également déterminée par la performance institutionnelle et les différences de systèmes sectoriels d'innovation. La comparaison entre les secteurs du café et des produits laitiers révèle ainsi que les stratégies des acteurs du café sont limitées. En ce qui concerne l’élaboration des politiques, cette thèse contribue aux politiques d’accompagnement de l’adaptation au niveau des ménages, aux politiques de recherche agronomique et de négociation des accords internationaux. Les recommandations politiques au niveau des ménages se différentient selon trois scénarios. En premier lieu de l’intensification dans le café par l’innovation technologique. Les deux autres options politiques sont dans la diversification sectorielle dans la production laitière qui dépend de leur niveau de rentabilité. Les résultats de cette étude sont issus d’enquêtes sur l’analyse des systèmes d’innovation. D’autres options politiques sont proposées dans le développement de nouvelles infrastructures, des subventions pour accroitre les potentiels d’adaptation. Nous recommandons enfin de nouveaux sujets de recherche pour le futurClimate change and variability is the most widespread anthropogenic challenge affecting agricultural production and productivity particularly in the tropics. Coffee sector is sensitive to climate change as it requires relatively cold temperature and higher rainfall duration. Adaptation to climate change in the coffee agroforestry is, therefore, important to address the impacts, but there are barriers, and limits. The aim of this Thesis was to analyze the adaptation strategies to climate change in Central Kenya. We studied the steps in adaptation, which includes (1) the knowledge on climate change and adaptation, the motivation towards adaptation, (2) current choices of households’ adaptation strategies, and their determinants, (3) the roles of innovation system and institutional context to support adaptation. This study was based on four sources of information: - (1) Focus Group Discussions to predefine the questionnaires, (2) household surveys, (3) stakeholders interview, and, (4) historical climate data. The data collection considered four farming typologies; - food crops, specialized coffee, diversified coffee-dairy and specialized dairy farming systems in the coffee and food crops zones. Mann-Kendal trend analysis and Sen’s slope estimator were used to compare the farmers’ knowledge of climate change with the historical climate data, while Heckman model was used to analyze adaptation strategies and their determinants. The findings explore consistent results between farmers’ knowledge and historical data analysis for temperature, while inconsistency is observed in rainfall change. Analysis of farmers’ perception revealed rainfall is radically declining over time, while no evidence in rainfall record is found to support the farmers’ perception. The inconsistency is therefore, substantiated with analysis of patterns. Coffee and food crop farmers are found to adapt to climate change differently. Farmers who are aware of the changes are found more willing to explore adaptation strategies although some of the farmers who do not perceive the climate is changing are also adopting strategies for factors other than perception. The comparison between coffee and dairy sectors found that actors in the coffee are limited, the system is highly centralized with limited options for farmers to process and market their products, while the dairy sector is informally controlled by demand based business and comparatively, numerous actors. We conclude in this study that the patterns in rainfall affects the farming activities of the study area higher than the annual changes. Consequently, farmers adopt a series of adaptation strategies in response to their perception of changes in climate and economic pressure in the farm. This adaptation to climate change also depends on the nature of actors’ interaction and institutional context. In relation to policy development, this Thesis contributes to household level adaptation policies, research policies and international agreements and negotiations. The household level policy recommendations consists of three scenarios. Farmers’ intensification in coffee applying the right technological innovations. The second and third policy options are the diversification to dairy and complete sectoral transformation to dairy depending on the profitability and adaptation level of the sectors. The results in this study are derived from surveys and analysis of innovation systems. Other strategies such as new infrastructural development and institutional subsidies could be potential for adaptation. We therefore, recommend, these could be potential future research topics

The potential of agroforestry in the British uplands depends largely on the ability of system components to efficiently use resources for which they compete. A typical system would comprise conifers planted at wide spacing, with sheep grazing pasture beneath. Computer models were developed to investigate the growth of trees and pasture in a British upland agroforest system, assuming that growth is primarily a function of light intercepted. Some of the implications of growing trees at wide spacing compared to conventional spacings, and the impact of trees on the spatial and annual production of pasture, were examined. Competition for environmental resources between trees and pasture was assumed to be exclusively for light: below-ground interactions were ignored. Empirical methods were used to try and predict timber production in agroforest stands based on data for conventional forest stands, and data for widely-spaced radiata pine grown in South Africa. These methods attempted to relate stem volume increment to stand density, age, and derived competition measures. Inadequacy of the data base prevented successful extrapolation of growth trends of British stands, although direct extrapolation of the South African data did permit predictions to be made. A mechanistic individual-tree growth model was developed, both to investigate the mechanisms of tree growth at wide spacings, and to provide an interface for a pasture model to examine pasture growth under the shading conditions imposed by a tree canopy. The process of light interception as influenced by radiation geometry and stand architecture was treated in detail. Other features given detailed consideration include carbon partitioning, respiration, the dynamics of foliage and crown dimensions, and wood density within tree stems. The predictive ability of the model was considered poor, resulting from inadequate knowledge and data on various aspects of tree growth. The model highlighted the need for further research into the dynamics of crown dimensions, foliage dynamics, carbon partitioning patterns and wood density within stems, and how these are affected by wide spacing. A pasture model was developed to investigate growth beneath the heterogeneous light environment created by an agroforest tree canopy. Pasture growth was closely related to light impinging on the crop, with temperature having only a minor effect. The model highlighted the fact that significant physiological adaptation (increased specific leaf area, decreased carbon partitioned below-ground and changes in the nitrogen cycle) is likely to occur in pasture shaded by a tree canopy.

While the light regimes of closed forest strands and open pasture have been quantitatively described and modelled, agroforestry involves greater complexity and spatial variability. This research involved intensive measurement of quantum flux density (QFD) above and below re-spaced tree strands of Sitka spruce (Picea sitchensis [Bong.] Carr.) and hybrid larch (Larix x eurolepis Henry) in conjunction with measurement of tree growth. QFD was also measured above and below pasture growing in boxes in imported soil sunk to ground level beneath the trees. The Monteith hypothesis that crop growth in unstressed conditions is linearly related to the amount of QFD intercepted by its canopy was found to hold for above ground growth of trees at agroforestry spacings. The overall dry matter: QFD quotient (e) for Picea sitchensis across the range of tree frequencies was 0.32 g mol-1 which is lower than typical values reported for agricultural crops, young container grown trees of Salix viminalis and Populus trichocarpa and closed-canopy Picea sitchensis, but comparable with previous estimates for a range of mature tree stands. e was unaffected by tree spacing, but was significantly higher for the tall tree stand which had been pruned. The mean annual QFD transmitted to the understorey varied from 39% to 96% of that in the open across the agroforestry treatments. The mean transmittance was similar but spatial variability of QFD was significantly higher in tree stands with crown to ground level when compared with stands having similar crown dimensions but which had been pruned to approximately 1.3 m height. More than 90% of seasonal pasture growth could be explained by a regression of growth on incident QFD.

Air pollution can lead to environmental impacts. Over the past decades there have been some success stories reducing pollutant emission, namely sulphur dioxide (SO2). However, impacts on ecosystems from atmospheric nitrogen (N) pollution are still seen as a major threat for European biodiversity. Across Europe over 70% of Natura 2000 sites are at risk for eutrophication with over 70% of the Natura 2000 area in Europe (EU28( exceeding critical loads for nutrient nitrogen deposition. Agricultural ammonia is a key contributor to the threat to these sites due to the close proximity of agricultural activities and protected sites. Source attribution modelling using an atmospheric transport model showed that agricultural livestock production in the UK is the dominant nitrogen source for N disposition across the UK Natura 2000 network. Nearly 90% of all sites had livestock as their dominant source, contributing 32% of the total nitrogen deposition across the whole network. 76% of all Special Areas of Conservation (SAC) sites exceeded their critical load for nutrient nitrogen, representing 74% of the entire SAC area. The extent of exceedance is also notable with many sites experiencing depositions of >50 kg N/ha/yr over the critical load. the situation for acidity critical load exceedance is less sever, by 51% of sites are still exeeded. Legislation to regulate pollutant emissions to air and protect biodiversity are often not integrated, and there has been no common European approach for determining the impacts of nitrogen deposition on individual Natura sites, or on conservation status. Off-site sources of air pollution present difficulties in assessing and attributing impacts, because deposition can result from local sources (1-2 km), or very far away sources (>1000 kms). Managing nitrogen losses on the farm and improving the efficient use of nitrogen are key components for overall reduction in NH3 emissions. Many nitrogen management options are available to abate ammonia from agricultural activities. On the one hand, technical and management measures include controlling emissions from manure storage and spreading, livestock feeding strategies, and improving housing systems. Trees, on the other hand, are effective scavengers of both gaseous and particulate pollutants from the atmosphere, making tree belts potentially effective landscape features to support ammonia abatement strategies. Using a coupled deposition and turbulence model the recapture efficiency of tree planting around ammonia sources was estimated. Using different canopy structure scenarios, tree depths and differing leaf area density (LAD) and leaf are index (LAI) were adjusted for a main canopy and a backstop canopy. Recapture efficiency for ammonia ranged from 27% (trees planted around housing systems), up to 60% (under-story livestock silvopastoral systems). Practical recapture potential was set at 20% and 40% for housing and silvopastoral systems respectively. Model results from scaling up to national level suggest that tree planting in hot spot areas of ammonia emissions would lead to reduced N deposition on nearby sensitive habitats. Scenarios for on-farm emission control through tree planting showed national reductions in nitrogen deposition to semi-natural areas of 0.14% (0.2 kt N-NHx) to 2.2% (3.15 kt N-NHx). Scenarios mitigating emissions from cattle and pig housing yielded the highest reductions. The afforestation strategy showed national-scale emission reductions of 6% (8.4 kt N-NHx) to 11% (15.7 kt N-NHx) for 25% and 50% afforestation scenarios respectively. Increased capture by the planted trees also generated an added benefit of reducing long-range transport effects, including a decrease in wet deposition of up to 3.7 kt N-NHx (4.6%) and a decrease in export from the UK of up to 8.3 kt N-NHx (6.8%). Agroforestry measures for ammonia abatement were shown to be cost-effective for both planting downwind of housing and in silvopastoral systems, when costs to society were taken into account. Planting trees was also cost-effective from a climate change perspective. Comparing the cost per kg of NH3 abated showed that planting trees is a method of ammonia emission mitigation comparable with other (technical) measures. The costs for planting trees downwind of housing were calculated at €2.6-7.3/kg NH3. Agroforestry for ammonia abatement offers multiple benefits for the farmer and synergistic effects for society as a whole including i) carbon sequestration. ii) visibility screening around housing units, iii) imporved animal welfare for silvopastoral systems, iv) reducing critical load exceedance on protected sites, v) price advantage of 'woodland chick' productions, vi) supporting the Industrial Emission Directive (IED) requirements for emission reduction, vii) supporting national afforestation policies. The results of this work support the notion that in the emerging discussion about the values of ecosystem services and the role of nature-based solution to tackle persistent environmental challenges, tree planting has a large potential in rural and urban environments.

L’ajout de diversité végétale est présenté comme un moyen d’améliorer la durabilité des agrosystèmes. Cependant, il y a encore des manques importants de connaissances sur l’effet de la diversité végétale sur les processus à la base de l’élaboration des rendements. Les systèmes agroforestiers tropicaux couvrent une large gamme de diversité végétale ; ce sont donc de bons modèles pour étudier la relation entre diversité et productivité. Les systèmes agroforestiers de la région de Talamanca au Costa Rica sont particulièrement intéressants car au sein de communautés végétales complexes, ils comprennent des bananiers et des cacaoyers qui sont des cultures de rente importantes et dont la production peut facilement être quantifiée et analysée. Une autre spécificité de ces systèmes est qu’ils présentent des organisations spatiales particulièrement diverses. Analyser comment la diversité des plantes et son organisation influe sur les performances de ces systèmes est particulièrement complexe et nécessite le développement de nouvelles approches. Les objectifs de cette thèse étaient d’étudier : i) quels facteurs affectent la relation entre diversité végétale et productivité ? ii) Comment la diversité végétale influence la productivité globale des systèmes agroforestiers ? et iii) Comment la structure spatiales des communautés de plantes cultivées influence leurs rendements ?Tout d’abord, une méta-analyse a été menée afin d’étudier la relation entre diversité végétale et production dans une très large gamme de systèmes naturels et cultivés. Cette analyse a notamment traité du rôle de la latitude, du climat et de la structure de la canopée sur cette relation. Elle a montré que le gain lié à la diversité végétal tend à diminuer avec la magnitude de cette diversité. Nos résultats montrent également que la réponse de la productivité à la richesse spécifique en plantes dépend énormément du type de communauté considéré, notamment si la communauté comprend des arbres.Ensuite, un réseau de 180 placettes situées dans 20 parcelles d’agriculteurs a été étudié dans la région de Talamanca. Pendant un an, la production de chaque plante a été évaluée. Cette production a ensuite été convertie en revenus en accord avec les prix du marché local. Alors qu’un effet positif de la diversité végétale cultivée a été observé sur le revenu globale (de chaque placette), cet effet était très contrasté si on le considérait séparément pour les différents groupes fonctionnels. Cet effet était positif pour les plantes des groupes appartenant aux strates hautes et négatif pour les plantes des groupes appartenant aux strates basses. Ces résultats suggèrent que la complémentarité entre plantes était plus forte pour les plantes des strates hautes et qu’inversement la compétition était plus forte dans les strates plus basses.La seconde phase de l’analyse des données de ce réseau de parcelles a visé à étudier l’effet du voisinage de chaque bananier ou cacaoyer sur leur production. Une approche d’analyse individu-centrée a été développée afin de déterminer si le nombre de voisins d’un groupe donné dans un rayon donné était un bon prédicteur de la croissance ou du rendement de chaque bananier ou cacaoyer. Les résultats montrent que la distance à laquelle la production d’un bananier ou d’un cacaoyer est affectée par ses voisins dépend de la taille de ces. De manière surprenante, les grands arbres ont eu un effet plus faible que les arbres plus petits. Cela suggère que des densités modérées de grands arbres pourraient être compatibles avec une production de bananiers et de cacaoyer avec un haut niveau de rendement. Ces résultats ont été discutés en termes de complémentarité et compétition pour la lumière. Des pistes d’organisation sont proposées et discutées au regard de la maximisation des rendements des cultures de rente et des autres cultures mais aussi dans la provision de services écosystémiques au sens largeAdding plant diversity is increasingly presented as a mean to improve the sustainability of agrosystems. However, there is still a lack of knowledge on how plant functional diversity alters processes that support production. Because they cover a broad range of plant diversity, agroforestry systems in the tropics are a good case study to better understand the diversity-production relation. Agroforestry systems in the Talamanca region in Costa Rica are particularly interesting because among the cultivated plants they encompass, banana and cacao are two cash crops of major importance and for which production can easily be quantified and analyzed. Another specificity of these systems is that their vertical and horizontal organization is particularly diverse. Understanding how plant diversity and its organization alter the performances of these complex systems is particularly challenging and requires developing new approaches. The objectives of this thesis were to address the following questions: i) Which factors affect the relationship between plant diversity and productivity? ii) How plant diversity influences the global productivity of agroforestry systems? and iii) How the spatial structure of the plant community affects yields?First, a meta-analysis was carried out to address the diversity-production issue among a very broad range of systems world-wide. This analysis focused on how latitude, climate, and canopy structure modify the effect of plant richness on productivity of agricultural and natural ecosystems. It showed that the gain per unit of diversity added decreased as plant richness increased. Our findings also showed that the response of productivity to plant richness largely depends on the type of plants in the community, especially if the community includes trees.Then, we extensively studied the diversity and the productivity of 180 plots located within 20 fields in the Talamanca region. A global evaluation of the productivity of these systems was possible with the estimation of the production of each plant during 1 year. This production was converted into income according to local market prices. While we observed a global positive effect of plant diversity on global income, this effect was contrasted according to the functional group considered (banana, cacao, other fruits, timber, firewood. When considering the functional group separately, there was a positive effect of plant diversity for higher strata groups and a negative effect for lower strata groups. This suggested that complementarity between plants was stronger than competition for those plants occupying the higher strata of the canopy but that competition was stronger than complementarity for plants occupying the lower strata of the canopy.The second part of the analysis of the Talamanca fields dataset focused on the effect of neighbouring plants on the production of banana and cacao plants. An individual-based analysis was developed to determine whether the number of neighbouring plants of a given functional groups explained the potential yield of each banana or cacao plant. We found that the distance at which other plants alters the yield of banana or cacao plants was greater for larger functional groups (fruit or wood trees) than for smaller ones (cacao trees or banana plants). Interestingly, higher strata trees had a smaller effect than lower strata trees, suggesting that moderate densities of tall trees could be compatible with high banana and cacao production. These findings were discussed in terms of complementary and competition with respect to the availability of light at higher and lower strata of the canopy. On an applied perspective, our results suggest that productivity could be maximized by a reasonably number of plant species, and then we proposed new direction to organize fields in order to maximize the production of cash crops while providing supplementary income for farmers and ecosystem services

Le débat sur d’autres façons de faire de l’agriculture est nécessaire et urgent. Les crisesqui ravagent la société mettent de plus en plus en évidence l’importance d’adapter lespratiques, les techniques et les outils pour produire dans les territoires rurauxd’Amazonie. L'agriculture familiale, y a pendant des siècles été fondée sur une pratiqueconsistant à couper et brûler la forêt, liée à l'agriculture itinérante. Des facteurs récentstels que la croissance démographique et la demande alimentaire ont intensifié les zonesde production pour répondre à la demande du marché. Cela met en danger desressources naturelles telles que l’eau, le sol et l’air. Repenser les modes de production etles systèmes de production est un point clé pour parvenir à une agriculture familialecapable de répondre aux aspects fondamentaux de la durabilité. En ce sens, les systèmesagroforestiers (SAF) sont une alternative adoptée par des agriculteurs familiauxd'Amazonie, car ils sont bien adaptés aux diverses réalités de la région, mais cessystèmes se répandent lentement. Ainsi, la présente recherche vise à identifier lesaspects liés aux barrières qui empêchent l'adoption et/ou la diffusion des SAF enagriculture familiale et les stratégies possibles à adopter qui peuvent contribuer à lessurmonter dans les territoires ruraux de l'Amazonie. La recherche a été menée dans leszones de plaine inondable d'Igarapé-Miri et sur les terres fermes de Tomé-Açu, dansl'est de l'Amazonie, en adoptant une approche de recherche qualitative-quantitative, àdes fins exploratoires et descriptives. À la fin de la recherche, comme principauxrésultats, nous avons identifié que la recherche sur les SAF s'est concentrée sur un débatplus socio-environnemental, tandis que les principales barrières identifiées tant auniveau de la propriété qu'aux multiniveaux spatiaux Local/Territorial etRégional/Fédéral, les facteurs limitant l’adoption des SAF sont liés à des facteurs socioéconomiques.Un autre résultat est de considérer à la fois les spécificités del'environnement biophysique pour structurer ces systèmes et les techniques à utiliserpour les mettre en oeuvre, en considérant divers aspects des exploitations tels que ladisponibilité de la main d'oeuvre, les ressources financières, le temps, le matériel, lesintrants, entre autres. Enfin, un autre résultat extrêmement important que nous avonsidentifié est lié aux relations de coopération et à la création de réseaux sur le territoire:ils s'avérent être des éléments stratégiques et fondamentaux pour surmonter les barrièresrencontrées et ainsi accompagner les agriculteurs familiaux dans la transitionagroécologiqueThe debate on other ways of farming is necessary and urgent. The crises that areravaging society increasingly highlight the importance of adapting practices, techniquesand tools to produce in rural areas of the Amazon. For centuries, family farming hasbeen based on a practice that consists of cutting and burning the forest, linked toitinerant agriculture. Recent factors, such as population growth and the demand forfood, have increased the production areas to meet market demand. This endangersnatural resources such as water, soil and air. Rethinking production methods andsystems is a key point to achieve family farming capable of meeting the fundamentalaspects of sustainability. In this sense, agroforestry systems (AFS) are an alternativeadopted by family farmers in the Amazon, as they are well adapted to the diverserealities of the region, but these systems are spreading slowly. Thus, the presentresearch aims to identify the aspects related to the barriers that prevent the adoptionand/or diffusion of AFS in family farming and the possible adoption strategies that cancontribute to overcoming them in rural areas of the Amazon. The research wasconducted in the floodplain areas of Igarapé-Miri and on the mainland of Tomé-Açu,Eastern Amazon, adopting a qualitative-quantitative research approach, withexploratory and descriptive purposes. At the end of the research, as main results, weidentified that research on SAF has focused on a more socio-environmental debate,while the main barriers identified both at the property level and at the multi-level spatiallevels Local/Territorial and Regional/Federal, the factors that limit the adoption of SAFare linked to socioeconomic factors. Another result is to consider both the specificitiesof the biophysical environment to structure these systems and the techniques used toimplement them, considering various aspects of the farms such as availability of labor,financial resources, time, materials, inputs, among others. Finally, another extremelyimportant result that we identified is linked to cooperation relationships and the creationof networks in the territory: they reveal strategic and fundamental elements to overcomethe barriers encountered and thus support family farmers in the agroecologicaltransition
O debate sobre outras formas de fazer agricultura é necessário e urgente. As crises queassolam a sociedade destacam cada vez mais a importância da adaptação de práticas,técnicas e ferramentas para produzir nos territórios rurais da Amazônia. A agriculturafamiliar baseou-se durante séculos numa prática que consiste no corte e queima dafloresta, ligada à agricultura itinerante. Fatores recentes, como o crescimentopopulacional e a procura de alimentos, intensificaram as áreas de produção parasatisfazer a procura do mercado. Isto põe em perigo recursos naturais como a água, osolo e o ar. Repensar os métodos e sistemas de produção é um ponto chave paraalcançar uma agricultura familiar capaz de atender aos aspectos fundamentais dasustentabilidade. Nesse sentido, os sistemas agroflorestais (SAFs) são uma alternativaadotada pelos agricultores familiares na Amazônia, pois estão bem adaptados àsdiversas realidades da região, mas esses sistemas estão se espalhando lentamente.Assim, a presente pesquisa tem como objetivo identificar os aspectos relacionados àsbarreiras que impedem a adoção e/ou difusão do SAF na agricultura familiar e aspossíveis estratégias de adoção que possam contribuir para superá-las nos territóriosrurais da Amazônia. A pesquisa foi realizada nas áreas de várzea do Igarapé-Miri e nocontinente de Tomé-Açu, Amazônia Oriental, adotando uma abordagem de pesquisaquali-quantitativa, com fins exploratórios e descritivos. Ao final da pesquisa, comoprincipais resultados, identificamos que a pesquisa sobre SAF tem se concentrado emum debate mais socioambiental, enquanto as principais barreiras identificadas tanto nonível da propriedade quanto nos multiníveis espaciais Local/Territorial eRegional/Federal, o os factores que limitam a adopção do SAF estão ligados a factoressocioeconómicos. Outro resultado é considerar tanto as especificidades do ambientebiofísico para estruturar esses sistemas quanto as técnicas utilizadas para implementálos,considerando diversos aspectos das fazendas como disponibilidade de mão de obra,recursos financeiros, tempo, materiais, insumos, entre outros. Por fim, outro resultadoextremamente importante que identificamos está ligado às relações de cooperação e àcriação de redes no território: revelam-se elementos estratégicos e fundamentais parasuperar as barreiras encontradas e assim apoiar os agricultores familiares na transiçãoagroecológica

Face aux besoins croissants pour une production agricole durable, les systems de culture évoluent vers des systèmes qui accomplissent des objectifs environnementaux et agricoles multiples. La recherche en conception de systèmes de cultures (CSC) s'intéresse à l'effet des pratiques et de l'environnement sur les systèmes de culture et leur performance. L'interaction entre production et services ecosystémiques, et la quantification de ces relations, sont un aspect clé de ce domaine de recherche. Une variété d'approches ont été théorisées, tels que l'utilisation de modèles et la mobilisation de connaissances expertes. Les modèles permettent de tester rapidement et à faible coût l'effet de pratiques agricoles dans une variété de conditions, mais l'application de conclusions théoriques à la parcelle peut être limitée par des contraintes locales ainsi que des obstacles à la communication chercheur-agriculteur. Mobiliser les agriculteurs et autres acteurs pertinents pour la CSC peut aider à surmonter ces obstacles ; cependant, cela limite l'innovation au cadre des connaissances expertes.L'objectif de cette thèse est de combiner la modélisation et des méthodes participatives pour une méthode de CSC qui exploite le potentiel de la modélisation numérique tout en s'assurant que les solutions proposées prennent en compte les contraintes environnementales et socioéconomiques. Après avoir revu l'état d'avancement de la recherche en prototypage et en CSC, nous proposons un cadre méthodologique divisé en quatre parties ; a) combiner une typologie des pratiques et un modèle conceptuel pour évaluer la diversité des pratiques, contraintes et trade-offs dans une zone de production ; b) acquérir des données de terrain pour quantifier les trade-offs pertinents entre production et services écosystémiques ; c) sélectionner et préparer un modèle numérique approprié pour simuler les effets des pratiques sur la production et l'apport de services ; et d) évaluer si l'interaction d'agriculteurs avec le modèle numérique peut générer des systèmes de culture potentiels qui répondraient aux objectifs agro-environnementaux posées (apport d'un service écosystémique) ainsi qu'être acceptables pour les agriculteurs qui les adapteraient à l'expérimentation dans leurs parcelles.The systèmes agroforestiers à base de café (cafés/arbres d'ombrage) du Costa Rica central ont étés le système de culture choisi pour répondre à ces questions. Les systèmes agroforestiers offrent de nombreuses occasions d'étudier et évaluer les services écosystémiques apportés, en plus de la production principale. L'association de deux cultures pérennes place l'évaluation de la performance à long terme et de la durabilité des systèmes au centre de la question. La culture du café au Costa Rica fait vivre une part importante de la population, et est aussi basée sur la gestion intensive d'une culture à haute valeur d'exportation, vulnérable aux fluctuations des prix sur le marché mondial ainsi qu'au changements climatiques. Des pentes raides et une saison des pluies importante créent des problèmes d'érosion significatifs ; cependant, certaines pratiques de contrôle de l'érosion (utilisation d'arbres d'ombrage et d'adventices) impactent la production de café. La réconciliation de ces deux aspects nous offrent l'occasion de tester notre cadre méthodologique dans une situation où une solide argumentation technique serait nécessaire pour encourager les expérimentations dans les parcelles. Enfin, le dernier chapitre porte une réflexion d'ensemble sur l'importance de choisir et préparer correctement un modèle agronomomique adéquat, les application potentielles de cette méthodologie, ainsi que les recommandations que nous avons pu effectuer en termes de pratiques de contrôle de l'érosion dans la zone d'étudeIn the face of increasing concerns about sustainability of agricultural production, cropping systemsare evolving towards systems that fulfill multiple agronomic and environmental objectives. Researchin cropping systems design (CSD) is concerned with studying the effect of farming practices oncropping systems and their performance. The interaction between production and ecosystemservices, and quantification of trade-offs between the two, is a key aspect of this research. A varietyof approaches have been theorized, such as use of models and mobilization of expert knowledge.Models allows fast and low-cost testing of the effect of farming practices under a variety ofconditions, but the application of theoretical outcomes to on-farm changes can be limited by localconstraints and researcher-farmer communication. Mobilizing farmers and other relevantstakeholders for CSD can help overcome these obstacles; however this limits innovation to the scopeof expert knowledge.The objective of this thesis is to combine modeling and participatory methods for a CSD frameworkthat harnesses the potential of numerical modeling while ensuring the proposed solutions take intoaccount socioeconomic and environmental constraints. After an overview of current advances inprototyping and CSD, we propose an methodological framework divided into four parts; a) combininga typology of farming practices and a conceptual model to appraise the diversity of farming practices,constraints and trade-offs at the plot scale in a defined production area; b) collection of field data forquantifying relevant trade-offs between production and ecosystem services; c) selecting andpreparing an appropriate numerical model for simulating the effects of farming practices onproduction and provision of ecosystem services; and d) evaluating whether the interaction of farmerswith a numerical model can generate candidate cropping systems that fulfill our agro-environmentalobjectives (provision of ecosystem service) as well as being suitable for the farmers who will adaptthem for on-farm experimentation.The coffee-based agroforestry systems (coffee/shade trees) of central Costa Rica were the chosenproduction system for answering these questions. Agroforestry systems offer plentiful opportunitiesfor valuing ecosystem services in addition to crop production; the combination of two perennialcrops brings long-term performance assessment and sustainability of the system to the heart of thequestion. Coffee cultivation in central Costa Rica concerns a large amount of livelihoods, but is alsobased on intensive management of a highly valued cash crop vulnerable to price fluctuations on theglobal market as well as climate change. Steep slopes and heavy rainfall also cause high levels of soilerosion; yet certain indirect erosion control practices (such as the use of shade trees of weeds) alsohave an impact on coffee production. The reconciliation of these two aspects offers the opportunityto test our methodological framework in situations where precise discussions onproduction/environment trade-offs are needed.Finally, in the last chapter we reflect on the importance of correctly choosing and preparing the rightmodel for the job, potential application of this methodology, as well as the recommendations wereable to make in terms of erosion control practices in the study area

Natural resources are in a constant state of depletion. The main reason being over exploitation of these resources and not contributing to their replenishment. To deal with these challenges, ecologists, leaders and experts have recommended the adoption of an agroforestry agriculture system. Agroforestry is more sustainable agricultural method that provides a long term vision to combat food insecurity. In spite of agroforestry being very useful, still individuals can not foresee it’s advantages. Serious games can motivate people in agroforestry scenarios and involve users in high interaction. GIS is a tool that can help in decision of proper location for agroforestry depending upon past data or information available. This paper defines a conceptual study for serious game to dynamically create 3D real-world agro-forestry environments. The serious games aim to provide visualization, intuitive management, and analysis of geospatial, hydrological and economic data to help participants for the decision support in agroforestry systems.

The current weather patterns, in the form of more frequent occurrences of hydrological extremes, are increasingly being felt in the Czech Republic. In this context, the paper focuses on the issue of the current management of the landscape, which loses its quality due to these adverse climatic conditions and the influence of man. The aim is to compare selected physical properties and obtained soil moisture data for different uses and cultivation. For sample collections, a site in the Czech Republic in the South Moravian Region in the district of Hodonin in the cadastral territory of Sardice was selected, where land improvements took place in the form of agroforestry systems. Broken and intact samples were taken from sampling sites (a grassy belt with trees and arable land), which were subsequently subjected to the necessary experiments in the laboratory. The data obtained were then evaluated on the basis of individual criteria and compared with each other. Furthermore, humidity and temperature are continuously measured using TOMST moisture sensors, these data are subsequently processed in the form of graphs. The results showed that the way the land is used and cultivated has an impact on the characteristics (quality) of the soil. So, we can influence them both negatively and positively.

This article discusses the benefits of using geographic information systems (GIS) for the assessment and management of agroforestry belts, which play an important role in sustainable agriculture. GIS technologies allow efficient collection and analysis of spatial data, which facilitates inventory and monitoring of agroforestry belts, as well as modeling of their environmental impact. Particular attention is paid to the use of GIS to integrate soil, climate and water data, providing an integrated approach to planning and management. Examples of successful implementation of the technologies in different regions demonstrate their potential to increase biodiversity, reduce soil erosion and increase crop yields. In conclusion, the need for further development of GIS technologies and training for optimal use of agroforestry belts within the framework of sustainable development is emphasized.

The aim of this study was to assess the ability of several distinct forestry systems in Bangladesh's northern region to sequester carbon. Three different agro-ecological zones (AEZs) were covered by the experiments: AEZ 1 (Old Himalayan piedmont plain), AEZ 3 (Tista meander flood plain), and AEZ 25 (Level barind tract). Experimental plots with three replications were randomly selected from each AEZ using a randomized complete block design (RCBD). Factor A, which represented five forestry models (Shal forest, social forest, eucalyptus cropland-based agroforestry, and mango and litchi orchard-based agroforestry systems), and Factor B, which represented the three aforementioned AEZs. To determine the total biomass accumulation, undergrowth vegetation (including herbs, shrubs, and crops) and tree growth parameters, like height and diameter at breast height (DBH), were studied. In terms of parameters like tree height, DBH, tree density, understory vegetation, and carbon sequestration in both trees and soil, the results showed significant differences across forestry systems. Notably, the Litchi orchard-based agroforestry system sequestered the least carbon, at 67.82 t/ha, whereas the Shal forest system did so at a rate of 2310.04 t/ha. Regarding the AEZs, AEZ 25 had the highest potential for sequestering carbon, measuring 644.98 t/ha, while AEZ 1 had the lowest potential, measuring 503.21 t/ha. Variability in carbon sequestration was also revealed by the interaction between AEZs and forestry systems. The Shal forest system and AEZ 3 were found to have the highest capacity at 2661.09 t/ha, while AEZ 1 and the Litchi orchards-based agroforestry system had the lowest capacity at 66.09 t/ha. In conclusion, the Shal forestry system demonstrated the highest capacity for conserving carbon and is, therefore, a promising strategy for reducing atmospheric carbon in the area. AEZ 25 demonstrated the best capacity for carbon sequestration of all the AEZs examined. Additionally, at $115,502/ha, the Shal forestry system provided the highest economic return on carbon sequestration. These findings suggest that the Shal forestry system should be given importance in Bangladesh's northern region for ecological reasons. Additionally, to balance carbon sequestration capacities between the zones, strategic tree planting programs should be implemented in AEZs 1 and 3.

This study demonstrates that the economic activity of the Amazon's natural forest has great potential yet to be developed when considering Non-Timber Forest Products (NTFPs) and those coming from agro-ecosystems (SAFs). Preliminary financial analyzes, in systems that are still incipient, point to a great potential for profitability of these alternative systems compared to traditional activities such as soybean and livestock farming, with the advantage of being conducted without degradation and deforestation, allowing the continuation with the support of the Amazonian ecological system. More research is needed to scale successful cases and more “dialogue” between the models of modern agriculture and the traditional knowledge to reach an integrated natural forest management system.

Case study from male and female Arabica coffee farmers in Vietnam. World Agroforestry, 2021. http://dx.doi.org/10.5716/wp21025.pdf.
Der volle Inhalt der QuelleAnnotation:
Estimates of carbon sequestration for timber trees is well documented, while fruit trees are understudied. The few existing estimates indicate that fruit trees and fertiliser management on them, can substantially sequester carbon in coffee monocultures, albeit unlikely to the same extent as timber trees. A carbon investor may thus favour timber. In this light, as programs for planting billions and trillion trees are launched “to save the climate”, a wide range of gender, social, justice and environmental concerns are voiced. To challenge the mitigation perspective, we contrasted two hypothetical tree planting strategies: a mitigation (carbon finance) perspective and a livelihoods-centred (local) perspective and explored what a rapid, gender and social inclusion-oriented livelihoods perspective could bring to the process of tree selection. The survey documents indigenous knowledge of trees’ potential (dis)benefits in coffee agroforestry systems among 106 female and male arabica-growers in northwest Vietnam. The results display many similarities between women and men in term of perceived benefits from trees. Women and men prioritized trees based on their economic benefits, impacts on coffee production and improved soil fertility. However, in determining the preferred species, women considered more factors, including consequences for pest and disease (on host tree or coffee), microclimate regulation and shade provision. These findings resemble those by others from the same region and demonstrate that consulting both women and men can result in a more diverse shortlist of potential trees for agroforestry/afforestation that reflect both genders’ economic and labour contributions to the household. Furthermore, tree planting projects would benefit from seeking collaboration for bundled ecosystem services, rather than merely from carbon finance. Conversely, carbon investors can rely on farmers’ preferences and rest assured that they also contribute to sequestering carbon.
