“…However, other variables such as formal education, family dependents, farming experience, household members helping in the farm, size of land area, expenditure and income from land cultivation, and maintenance activities can be categorized as sufficient. Agroforestry cultivation costs were mainly related to labor, including support from family members (Padovan et al 2022). Family labor contributes to reducing production costs in agroforestry systems (Bucheli et al 2021).…”

Proper policy is crucial to support the development of forest areas. Therefore, good planning based on supporting data is crucial. All information considering farmers’ conditions and interests in Talang Mulya Village, situated around Wan Abdul Rachman Forest Park, is urgently needed. So far, policies and programs launched have only been general and inappropriate to implement for the whole farmers. The main objective of this research was to perform fast agroforestry farmers clustering with differences in the main characters to each other using the K-means clustering algorithm and Elbow method based on 10 variables of social and land cultivation conditions. Results showed that agroforestry farmers in Talang Mulya Village could be best divided into 4 clusters with the proportion of 30%, 40%, 23.3%, and 6,67% for clusters 1, 2, 3, and 4, respectively. Agroforestry farmers were dominated by farmers with the specific characteristics of the lowest number of families working on the land and the cultivated main plant species with a sufficient level of formal education, family dependents, farming experience, household members that help in the farm, size of land area, expenditure and income from land cultivation, and maintenance activities. The research results could be used as a consideration for determining specific and targeted activity programs to increase the cultivation capabilities and welfare of farmers in Talang Mulya Village.

“…A aroeira conduzida em plantios comerciais potencializa, aperfeiçoa e amplia a silvicultura. Pode-se incluí-la tanto na linha de Espécies Florestais Não Tradicionais (EFNT), na qual a pimenta-rosa é um produto florestal não madeireiro de exportação, como também ser utilizada com sucesso em Integração Lavoura, Pecuária e Floresta (ILPF) e Sistemas Agroflorestais (SAF), agregando renda para os produtores e restauração florestal com benefícios para o meio ambiente (PADOVAN et al, 2021). No entanto, ainda existe carência de estudos e alternativas de espécies nativas da Mata Atlântica contribuindo nesses sistemas complexos, principalmente em estágios iniciais, nos quais cumprem papel ambiental e ainda ofertem produtos de interesse comercial, sendo prioritário no âmbito do sistema agrícola capixaba, destacando o Espírito anto como maior produtor e exportador da pimenta-rosa do país.…”

The aroeira or Brazilian peppertree (Schinus terebinthifolia) is native to the Atlantic Forest Biome and its fruit, the pink pepper, is a Brazilian export product that, due to its flavoring characteristics and chemopreventive substances, such as flavonoids and other phenolic compounds, stands out in the food, pharmaceutical and cosmetics industries. The state of Espírito Santo, the largest producer and exporter of pink pepper in the country, meets growing demand in the international market and seeks new markets. Since 2016, the Capixaba Institute for Research, Technical Assistance and Rural Extension (Incaper) created the Working Group "GT Aroeira", including researchers and rural extension workers to meet the demands arising from the transition from purely extractive activities to commercial cultivation of aroeira as an agricultural crop. In 2019, the Aroeira Producers Association of Espírito Santo (Nativa) applied to the National Institute of Industrial Property (INPI) for the Geographical Indication (IG) of Espírito Santo pink pepper, in the Indication of Origin (IP) sub-type. This certification represents a major advance for the activity, qualifying the product and valuing the actors who are dedicated to fulfilling all the requirements of good practices in the various links of the production chain. The Nativa must accompany the process ensuring the good use of this register, and avoiding discontinuity of actions and disuse of the IP. In view of the consolidation of the work, Incaper, with the Institute of Innovation and Sustainable Technologies (Inovates) and partner institutions adjusted the route of the IG referrals, subsidizing a new request from Nativa for the delimitation of the geographical area of the Indication of Origin "SÃO MATEUS" for the Pink Pepper in Espírito Santo.

“…Além de benefícios ecológicos, integrar a produção agrícola e florestal à processos de recuperação de áreas degradadas incluem outras vantagens, como: estender o período de gerenciamento da restauração; compensar os custos associados a restauração, pela possibilidade de retorno financeiros a curtos, médios e longos prazos; promover a segurança alimentar de famílias e comunidades e; envolver ativamente os agricultores no processo de restauração, o que resulta em melhores resultados de conservação (GIUDICE BADARI et al, 2020;PADOVAN et al, 2022;PADOVEZI et al, 2018;VIEIRA, HOLL e PENEIREIRO, 2009).…”

“…Esse sistema planejado para restaurar áreas, que contava com 20 espécies de árvores nativas e o cultivo associado de espécies anuais, em uma análise econômica apresentava retorno econômico apenas após 14 anos de implantação. Com base nos resultados obtidos, foi realizada a modelagem de um novo SAF, que com mudanças no arranjo, na seleção de espécies e manejo, o payback passou a ser de apenas 2 anos(PADOVAN et al, 2022).Portanto, para assegurar um manejo sustentável que garanta a consolidação dos processos de restauração ecológica alinhado com a sustentabilidade econômica dos SAFs, a seleção de espécies multifuncionais, com características silviculturais e agronômicas adequadas à estas finalidades, juntamente com um bom planejamento de arranjos e designs que otimizem as interações ecológicas positivas, são de fundamental importância.2.4. ONo Brasil, as primeiras pesquisas de silvicultura orientados para a eucaliptocultura começaram em 1904, no município de Jundiaí/SP, e em 1909 no município de Rio Claro/SP, estudos estes financiados pela Companhia Paulista de Ferrovias e coordenados por Edmundo Navarro de Andrade(GONÇALVES et al, 2013).Os amplos conhecimentos difundidos sobre a espécie, resultado de anos de pesquisa envolvendo diferentes materiais genéticos e a interação desses com o ambiente, juntamente com políticas de incentivos fiscais, e a facilidade na aquisição de mudas, auxiliaram na adoção e expansão do plantio de eucalipto nas propriedades rurais(GONÇALVES et al, 2013; IBÁ, 2020), alcançando no ano de 2020, a marca de 7,47 milhões de hectares plantados no país(IBÁ, 2021).O Brasil, considerado uma referência mundial, apresenta a maior produtividade, medida em volume de madeira produzida por unidade de área ao ano, e a menor rotação do mundo(IBÁ, 2020).…”

The management of the light ambient in multipurpose agroforestry systemsConsidering the great diversity of native tree species and the modest advances of silviculture on these when in productive systems, this study aimed to verify the responses of different native species to the variation of the light environment. For this, the eucalyptus stands were thinned systematically and progressively, providing gradual differences in the canopy cover. The experiment with four non-randomized blocks consisted of five treatments with different levels of forest density, T100 -100% of eucalyptus, T75 -75% of eucalyptus, T50 -50% of eucalyptus, T33 -33% of eucalyptus and T0 -without eucalyptus/full sun, and three sub-treatments, S1 -Pioneer (PIO), S2 -Non-pioneer (NPIO) and S3 -Mixed planting (MIX). For the eucalyptus crop, the average annual increment and the basal area were characterized as results of the differential thinning in each treatment. The T33 treatment, due to the reduction in competition, provided the highest diametric gains, 2.2 cm/year/tree, but presented the lowest basal area given the lower forest density. The monitoring of the eucalyptus canopy was performed using hemispherical photographs. Higher intensities of thinning provided larger spaces for the canopy growth, resulting in more significant gains in the canopy coverage index. With light sensors arranged under different conditions of vegetation cover, the light conditions present in the understory of each treatment were measured. The available light in the treatments ranged from 41.01-to 91.50% of the maximum possible luminosity at the beginning of the experiment and from 35.35% to 83.41% at the end of the observations. The forty species of Brazilian native trees (20 pioneer species and 20 nonpioneer species) implanted in the system, which were submitted to different radiation conditions, were evaluated in a census for mortality, height growth, increase in diameter at root collar, and observation of responses plastic. For mortality, a continuum of responses was observed, with trends of higher mortality in the opposite extreme conditions of radiation found in treatments T0 (full sun) and T100 (more shaded environment). The group of pioneer species showed the highest plasticity for growth in height; the response known as "shadow avoidance syndrome" was driven by treatments T75 and T50. The highest diametric gains for all sub-treatments (PIO, NPIO, MIX) were provided by full sun conditions (T0). The species Schinus terebinthifolius (Aroeira pimenteira) and Peltophorum dubium (Canafístula) were individually analyzed. Due to their different uses and economic potential, which are optimized by different light conditions, it is recommended that S. terebinthifolius be cultivated in full sun and P. dubium in the shade (approximately 45% of available solar radiation).
