vaca terneroLo que comen las vacas también influye en la atmósfera

Seguro que pocas veces te has planteado que lo que come una vaca, una oveja o cualquier otro rumiante también puede tener una influencia en las emisiones de ciertos gases a la atmósfera. Un equipo de investigadores de la Universidad Politécnica de Madrid ha analizado hasta qué punto la dieta de los animales influye en las emisiones de nitrógeno y metano que llegan al aire que respiramos y han buscado soluciones prácticas a este problema.

El primer paso para entender por qué la dieta animal puede influir en los gases existentes en el aire es comprender qué pasa cuando comen los rumiantes. “En los procesos digestivos de los rumiantes se genera metano, un gas con un efecto invernadero 23 veces mayor que el del CO2. La mitad de las emisiones antropogénicas de metano en España es producido por los animales de granja, siendo los rumiantes los principales contribuidores”, explica María Dolores Carro, profesora de la  Escuela Técnica Superior de Ingeniería Agronómica, Alimentaria y de Biosistemas de la UPM (España) y una de las autoras del estudio.

silvicultura finlandiaMonday guest: Biocoal a new dimension in forest energy

Summary:
Veli Pohjonen, professor of agriculture and forestry at the University of Helsinki, writes into Kainuun Sanomat about the history of forest energy use in Finland, which started in 1956 when the first Austrian Pöttinger harvester was brought into the country. Wood from thinnings was wanted for heating plants. In 2009, six million cubic metres of woodchip were imported to Finland. That is just over 10% of Finland's harvesting volume. Wood pellets came to Finland in 1979 and now the country has 30 pellet factories.

abeja plantaLos pesticidas y la desnutrición matan a las abejas

La combinación de ambos factores demuestra unos efectos sobre las abejas muy superiores a la suma de cada uno de ellos por separado.Los efectos combinados de los pesticidas y la falta de nutrición forman un golpe mortal para los animales, según ha demostrado una nueva investigación de biólogos de la Universidad de California en San Diego, en Estados Unidos. En un estudio publicado este miércoles en Proceedings of the Royal Society B, Simone Tosi, James Nieh y sus colegas utilizaron abejas debido a su importante papel como polinizadores agrícolas y "bioindicadores" de calidad ambiental.
