Use of columnar cacti in the Tehuacán Valley, Mexico: perspectives for sustainable management of non-timber forest products

Sustainable management of non-timber forest products such as palm fruits is crucial for the long-term conservation of intact forest. A major limitation to expanding sustainable management of palms has been the need for precise information about the resources at scales of tens to hundreds of hectares, while typical ground-based surveys only sample small areas. In recent years, small unmanned aerial vehicles (UAVs) have become an important tool for mapping forest areas as they are cheap and easy to transport, and they provide high spatial resolution imagery of remote areas. We developed an object-based classification workflow for RGB UAV imagery which aims to identify and delineate palm tree crowns in the tropical rainforest by combining image processing and GIS functionalities using color and textural information in an integrative way to show one of the potential uses of UAVs in tropical forests. Ten permanent forest plots with 1170 reference palm trees were assessed from October to December 2017. The results indicate that palm tree crowns could be clearly identified and, in some cases, quantified following the workflow. The best results were obtained using the random forest classifier with an 85% overall accuracy and 0.82 kappa index.

Non Timber Forest Products

Non-timber Forest Products (NTFPs) play an important role as traditional source for food, fiber, fodder, and medicine and offer income opportunities for poverty alleviation especially in rural households in Nepal who engage in a widespread trade of NTFPs. Adequate planning for sustainable use of NTFPs is imperative so we explored the inventory of multipurpose trees and herbs that are being used as NTFPs in Chitwan, Nepal. 70 households from Sukranagar and Mangalpur VDCs of Chitwan district were randomly selected and personal interviews were taken with them as well as focus group discussions were done. The community had been utilizing 49 plant species from the nearby community forest. Implementation of the policy of community forestry was found to have a positive impact on the sustainable production of NTFPs. More than 80% of the respondents believed that indigenous knowledge promoted sustainable NTFP production. Kurilo (Asparagus officinalis) was found to be the best NTFP for the study site. Various policy level reforms are proposed that will help in improving the sustainable production of NTFPs. Better utilization of NTFPs as well as their conservation is possible with proper trainings given to community forest users.International Journal of Environment Vol.5(3) 2016, pp.87-103

Over Exploitation

Non-timber forest products (NTFPs) consist of goods of biological origin other than wood, derived from forests, other wooded land and trees outside forests. The importance of NTFPs for sustaining rural livelihoods, fostering rural poverty alleviation, enhancing biodiversity conservation, and facilitating rural economic growth is well known in Nepal. In spite of these facts, NTFPs have not received the sustained and systematic support. With the gradual rise in population, unsustainable harvesting and depletion of resources, sustainable management of NTFPs has become a challenge. Similarly, the increasing global demand of NTFPs leads to over-exploitation of these resources that further leads to dwindling and adversely affecting the biodiversity. In this context, this paper intends to explore and analyze the conservation status, prospects and challenges for efficient and sustainable management of NTFPs in the context of Nepal.

The Upper Bandama fauna and flora reserve, which is part of Côte d'Ivoire's biodiversity conservation strategy, is threatened by the pressure of human activities. The purpose of this article is to make a socio-economic assessment of the exploitation of the natural resources of this protected area. Specifically, it is question of knowing the forms of activities which are developed there, the actors, the strategies of infiltration, and to determine the factors related to this occupation. Based on a data collection work that combines documentary research, semi-structured interviews and direct observation, artisanal gold mining, farming, poaching, fishing and collection of non-timber forest products have been identified as the major forms of degradation of this reserve. These activities involve different profiles of actors who have accessed the reserve under various conditions. They can be explained by the economic dynamism of the peripheral zone, the recomposition of this zone in the face of demographic pressure and land issues, the non-integration of the legal status of the reserve and the invisibility of the key actors. The study ends with perspectives for sustainable management of this reserve.

Traditional zone of Meru Betiri National Park (TNMB) has been enacted as a traditional used-area by community who had high dependency on natural resources for generations. Utilization of Non-Timber Forest Products (NTFP) in TNMB in the form of durian was conducted on the area of 25ha spread over 12 blocks with the total number of at least 925 trees (ϕ of >150 cm). Several problems occurred in NTFP management such as: (a) conflict of interest between durian user group and local people, (b) no legacy of NTFP utilization group in TNMB, (3). Low price of durians and no processing durian products. The objectives of this study were to evaluate the internal and external key factors influenced the management of NTFP and to determine the effective strategies to strengthen the sustainable management. Analysis was performed using SWOT with matrix of internal and external factors. The results of this study showed that there were seven (7) factors of each factors of Strength, Weakness, Opportunity and Treat influenced the NTFP management. In general, the conditions of NTFP management in traditional used- area in TNMB was in the position of internally strong and could be improved by developing potential opportunities and reducing the negative effects of potential threads.

Sensorial Attributes

Abstract Background Fermentation is an ancient technique for preserving and improving the qualities of food and beverages throughout the world. Microbial communities, not seen by the producers of fermented goods, are the actors involved in the fermentation process and are selected upon through different management processes in order to achieve a final product with culturally accepted features. This study documented the preparation of “colonche” which is a type of traditionally fermented beverages made with the fruits from several cactus species in two main producing regions of Mexico, the Altiplano and the Tehuacán Valley. We documented the selection processes of the cactus species used and the practices that could influence microbial community composition, as well as, how the producers reach the desirable sensorial attributes of the beverages. Methods We conducted 53 semi-structured interviews and participatory observations with colonche producers in 7 communities of the Altiplano and the Tehuacán Valley in order to characterize the practices and processes involved in the elaboration of the beverage. Opuntia and columnar cacti species used in colonche production were collected during fieldwork and identified. Selected sensorial attributes of Opuntia colonches were characterized by a ranking table and visualized by principal component analysis in order to distinguish differences of this beverage in the Altiplano localities. Results Thirteen cactus species are used for colonche production in both regions studied. In the Altiplano, the most commonly used fruit is Opuntia streptacantha because it contributes to the preferred attributes of the beverage in this region. Selection of substrates by producers depends on their preference and the availability of fruits of O. streptacantha and other species. Fermentation is mainly conducted in clay pots which is perceived to be the best type of vessel contributing to the preferred sensorial properties of colonche. The two main differences in colonche preparation between the villages are the practice of boiling the fruit juice and the use of pulque (fermented sap of Agave species) as inoculum. The most contrasting sensorial attributes selected between localities are the alcohol content and sweetness, which might be in accordance with the practices used for obtaining the final product. Colonche is produced mainly for direct consumption and secondarily used as a commercialized good to be sold for economic gains contributing to the general subsistence of households. The preparation methods are passed on by close relatives, mainly women. Conclusions Traditional producers of colonche use several techniques in order to reach specific sensorial attributes of the final product. The production of colonche has been upheld for generations but fermentation practices are divided into two categories; (1) the use of an inoculum (either from pulque, or from colonche saved from the previous year), and (2) the use of “spontaneous” fermentation. The differing practices documented reflect the contrasts in the preferred sensorial attributes between regions. Colonche is a beverage that contributes to regional pride, cultural identity and is appreciated because of its gastronomic value. Here, we argue that there is a clear relationship of human knowledge in the management of microbiota composition in order to produce this beverage. In-depth documentation of the microbiota composition and dynamics in colonche will contribute to the preservation of this valuable biocultural heritage.
