La prospectiva como marco de análisis para el aprovechamiento turístico de los hongos comestibles silvestres (HCS) en el centro de México

Los hongos comestibles silvestres (HCS) han sido aprovechados históricamente por las comunidades forestales, pues constituyen un componente fundamental de su cultura alimentaria y un recurso estratégico de subsistencia. Además, representan una oportunidad para la diversificación productiva local a partir del impulso del turismo rural orientado al micoturismo. Por este motivo, se delinea un marco de análisis teórico metodológico desde el enfoque de prospectiva. Como procedimiento metodológico se realizó una revisión de literatura del micoturismo y de los HCS en revistas científicas. Como resultado se identificaron 48 variables que inciden en la conformación del sistema micoturístico y que son una aproximación para generar escenarios futuros del aprovechamiento recreativo de los hongos comestibles silvestres

Caracterización productiva y socioeconómica del sistema de producción ovina, en un área natural protegida de México

Ante el incremento de la presencia humana y sus actividades productivas en áreas naturales protegidas, se planteó el objetivo de caracterizar el sistema de producción ovina, en el Nevado de Toluca, con información agrícola, socioeconómica y uso de los recursos de pastoreo. Un total de 162 productores fueron entrevistados, se analizaron 25 variables con estadística multivariada y univariada. Mediante análisis de componentes principales se obtuvieron seis factores que explican el 71 % de la varianza. El análisis cluster permitió identificar tres grupos de productores: pequeños (28 %), intermedios (35 %) y capitalizados (6 %), diferenciados por el número de animales, superficie cultivada e ingresos (P0.05) y se encontró que los rebaños aportan menos del 30 % del ingreso familiar. El 58 % de los rebaños ingresa al bosque, para realizar pastoreo circulante, pero el 60 % se maneja semi-estabulado. Se concluye que la producción del sistema no depende de la capitalización del productor, pero el rebaño es esencial en la economía familiar, y el manejo de los animales es compatible con los esfuerzos de conservación del área natural protegida

Servicios ecosistémicos de provisión suministrados por agroecosistemas de huertos familiares del Estado de México

Introduction: Provisioning ecosystem services (ES) provided by agroecosystems of family orchards (AEFO) refer to the tangible benefits that people obtain from the ecosystem. Although AEFO have been widely studied, few studies show their approach from an integral perspective, which incorporates biophysical and economic characteristics at the same time. Objective: To carry out an integral analysis of provisioning ecosystem services provided by agroecosystems of family orchards from State of Mexico. Methods: Information about provisioning ecosystem services (identification, uses, destination and income gen- eration) were collected between March to December 2019 from three rural communities by involving 42 families with a family orchard using semi-structured interviews, questionnaires, species inventories, direct observation and field trips. Results: A sum of six provisioning ecosystem services were identified, which were associated to 212 species, distributed in 172 genera and 82 families. The main uses that the owners of the orchards gave to provisioning ES were ornamental (51 %), followed by food (39 %) and medicinal (32 %), where species such as Cymbopogon citratus, Persea americana, Punica granatum, Zea mays e Inga jinicuil, had the highest use values (U. V. = 4). The destination of the production was self-consumption, sale and exchange, being the first the main survival strategy used by households. Sale of edible products in fresh, as well as their derivatives, represented an average gross income of 1 333.47 USD/year for the owners of the family orchards. Conclusions: Provisioning ecosystem services provided by family orchards seen as an important source of resources, which allow the households of rural communities classified in extreme poverty to cover multiple needs

Weed control with small ruminants: Exploratory evaluation on Senecio inaequidens

Objective: Carry out an exploratory evaluation of sheep and goats grazing in a temperate pasture invaded by Senecio inaequidens, as a means of biological control of weeds in small-scale dairy systems (SSDS). Methodology: Crude protein (CP), neutral detergent fibre (NDF), and acid detergent fibre (ADF) were determined on pasture and Senecio samples. The effect of grazing by sheep and goats on the pasture was assessed by means of the height, density and soil cover of Senecio, and also sward height; and the live weight of the animals, daily weight gain and body condition score were recorded. Statistical analysis was by a 2x2 factorial design, with species (sheep or goat) and two grazing intensities at 28.3 or 50.3 m2/animal per day. Results: height, coverage and density of Senecio did not show significant differences (P>0.05), neither did sward height. The chemical composition of the pasture did not show statistically significant differences for the assessed periods either. Animal weight, body condition and daily weight gain did not show significant differences among the evaluated treatments (P>0.05). Implications: This is the first report evaluating sheep and goat grazing to control of Senecio invasion in temperate pasture in central Mexico. In addition, knowing the chemical quality of Senecio will allow decisions to be made for supplementation in grazing systems with sheep or goats. Conclusions: The grazing of sheep and goats reduced the number of Senecio plants in the assessed pasture, which indicates the possibility of controlling this weed by grazing sheep or goats over longer-term grazing.Objective: Carry out an exploratory evaluation of sheep and goats grazing in a temperate pasture invaded by Senecio inaequidens, as a means of biological control of weeds in small-scale dairy systems (SSDS).

Factors influencing the use of cultivated grassland for smallscale dairy production in the Central Highlands of Mexico

This paper identifies the socio-economic and farm variables and cognitive and social factors influencing the use of cultivated pastures by small-scale dairy farmers. A field survey was conducted. The sample was divided in two groups defined as: users (Group 1, n= 55) and non-users of the innovation (Group 2, n= 51). Data were analysed through the Mann Whitney test and the Theory of Planned Behaviour (TPB). Socioeconomic and farm variables influenced the use of cultivated grassland, as observed in Group 1. This group showed a bigger proportion of farmers (60 %) who indicated a positive intention to use cultivated grasslands, in comparison with 36 % of farmers from Group 2. Farmers from both groups perceived similarly the utility and importance of the use of cultivated grassland; however, farmers’ intention of Group 1 showed a significant correlation (P<0.05) with utility and importance. Other factors influencing the use of cultivated grasslands were the positive beliefs, social referents and difficulties perceived of the innovation. It concludes that different factors influenced the use of cultivated grassland in each group

Evaluation of the botanical composition of kikuyu and fescue grasslands associated with white clover during two seasons in the high valleys of Mexico

Objective. To evaluate the botanical composition of grasslands of kikuyu (Cenchrus clandestinus) compared to tall fescue (Lolium arundinaceum cv. Cajun II), each one in association with white clover (Trifolium repens cv. Ladino), in two independent experiments conducted during two seasons, autumn 2018 and winter 2019. Methodology. Two independent experiments under small-scale milk production system (SMPS) were established in the municipality of Aculco, State of Mexico, during autumn 2018 and winter 2019. The botanical composition of grasslands under intensive continuous grazing by breeding cows was evaluated. One grassland planted with tall fescue cv. Cajun II and the other invaded by kikuyu; each grassland was associated with white clover cv. Ladino. The botanical composition of both experiments was analyzed using a complete randomized experimental design. Results. The kikuyu grassland recorded significant differences (p&lt;0.05) with a higher proportion of forage during the winter 2018. Whereas the tall fescue cv. Cajun II grassland recorded a proportion of forage (p&lt;0.05) higher than its proportion of dead tissue during autumn 2019. Study Implications: The study of the botanical composition of mixed grasslands destined for livestock grazing allows to identify, propose and define strategies for forage production facing agroclimatic and management conditions in order to generate a better and higher forage yield. Conclusions: The proportion of kikuyu was higher than that of tall fescue cv. Cajun II during the two seasons and years evaluated. This highlights the adaptability of kikuyu grass under agroecological conditions such as the absence of rains and high temperatures, coupled with the high stocking densities of the milk production systems in the study region

Farm and socio-economic characteristics of smallholder milk producers and their influence on technology adoption in Central Mexico

In order to identify the factors influencing adoption of technologies promoted by government to small-scale dairy farmers in the highlands of central Mexico, a field survey was conducted. A total of 115 farmers were grouped through cluster analysis (CA) and divided into three wealth status categories (high, medium and low) using wealth ranking. Chi-square analysis was used to examine the association of wealth status with technology adoption. Four groups of farms were differentiated in terms of farms’ dimensions, farmers’ education, sources of incomes, wealth status, management of herd, monetary support by government and technological availability. Statistical differences (p < 0.05) were observed in the milk yield per herd per year among groups. Government organizations (GO) participated little in the promotion of the 17 technologies identified, six of which focused on crop or forage production and 11 of which were related to animal husbandry. Relatives and other farmers played an important role in knowledge diffusion and technology adoption. Although wealth status had a significant association (p < 0.05) with adoption, other factors including importance of the technology to farmers, usefulness and productive benefits of innovations together with farmers’ knowledge of them, were important. It is concluded that the analysis of the information per group and wealth status was useful to identify suitable crop or forage related and animal husbandry technologies per group and wealth status of farmers. Therefore the characterizations of farmers could provide a useful starting point for the design and delivery of more appropriate and effective extension
