La ecotecnología la podemos encontrar tanto en dispositivos como en métodos y procesos que promueven el aprovechamiento sustentable de recursos naturales, al tiempo que propician beneficios sociales y económicos en contextos específicos. Con esta premisa se creó el Laboratorio Nacional de Innovación Ecotecnológica para la Sustentabilidad.

Despite alleged advantages of organic over conventional farming, management effects on biodiversity are still little known. We related the diversity of herbs and flower visitors to management indicators in avocado orchards and hypothesized that inputs, practices, and context influence diversity of herbs and flower visitors. Using basic classification units, matrix correlation, and multivariate analysis of variance, we found that low-toxicity insecticides, infrequent herb cutting, and presence of forest areas were related to high biodiversity. Intensification of agricultural management reduced biodiversity both in organic and conventional management type. Our results advocate for an improved, integrative, management classification considering intensification and ecological context, besides input-type criteria.

Resumen en español

En México y en el mundo, la incorporación de la comunidad científica (entre ellos los ecólogos) a la generación de conocimientos que coadyuven a solucionar los graves problemas ambientales, y avanzar hacia la sustentabilidad, requiere de una visión diferente en la investigación. Más aún, se requiere de herramientas novedosas para acoplar el trabajo de la comunidad científica con el resto de la sociedad. Los ecólogos tienen el reto devolverse innovadores y creadores de nuevos modelos, procesos de colaboración, métodos y herramientas de investigación, básica y aplicada, entemas como la agricultura, la forestería, la ganadería y el uso de los recursos naturales. Para enfrentar este reto, los ecólogos en México necesitan amalgamar su quehacer con el de otros actores académicos y no académicos para impulsar en conjunto procesos de mejoramiento ambiental con beneficios sociales. En esta contribución se revisan retos y perspectivas que se tienen en México en el campo de innovación ecotecnológica. Se propone fomentar el trabajo de investigación en laboratorios sin muros, en los cuales grupos flexibles de actores diseñen, prueben y evalúen innovaciones tecnológicas que respondan a problemáticas ambientales y socioecológicas locales y regionales específicas.

Resumen en inglés

In Mexico and in the world, the incorporation of the scientific community (among them ecologists) to the generation of knowledge that contributes to solving the serious environmental problems, and advancing towards the sustainability, requires a different research vision. Moreover, innovative tools are needed to couple the work of the scientific community with the rest of the society. Ecologists are challenged to become innovators and creators of new models, collaborative processes, methods and research tools, basic and applied, in topics such as agriculture, forestry, livestock andthe use of natural resources. To meet this challenge, ecologists in Mexico need to amalgamate their work with other academic and non-academic actors to jointly promote environmental improvement processes with social benefits. This contribution examines challenges and perspectives of ecotechnological innovation in Mexico. We suggest to foster the research work in this field in laboratories without walls, in which flexible groups of actors design, test, and evaluate ecotechnological innovations that respond to specific local and regional socio-ecological and environmental problems.

Plantations are frequently established on abandoned pasture lands to speed forest recovery. This strategy requires matching a tree species mix with the prevailing microenvironmental conditions. In four degraded pastures of the Mexican Lacandon rainforest, we planted 2,400 trees of 6 species (Guazuma ulmifolia, Inga vera, Ochroma pyramidale, Trichospermum mexicanum, Bursera simaruba, and Spondias mombin) to (1) test survival, initial growth, and establishment costs; (2) evaluate whether vegetative cuttings outperform direct seeding or transplants of nursery-raised seedlings; (3) determine tree response to herbaceous dominance and soil compaction; and (4) scrutinize the results' consistency across sites and sampling scales of tree–microenvironment interactions (individual tree vs. averaged plot responses). After 2 years, overall survival and growth rates were high for 2 of 3 nursery-raised species. Contrary to expectations, all seedlings outperformed the cuttings while direct seeding resulted in a cost-effective option of intermediate efficacy. The impact of soil resistance to root penetration on tree biomass accumulation was species dependent while bulk density was not relevant. Soil-covering, herbaceous vegetation accelerated growth in 3 of 4 tested species during the dry season. At this initial stage of forest restoration in abandoned pastures, Guazuma and Trichospermum were the most restoration-effective species. Costs can be reduced by using direct-seeding Inga and avoiding weeding during the dry season. Finally, our results demonstrate how species selection trials can be misleading due to site variations in tree response and to sampling scales that fail to account for small-scale environmental heterogeneity. We recommend ways to improve the design of restoration trials.
