BIOCHAR: HOPE FOR A BRIGHTER TOMORROW IN THE BATTLE AGAINST GLOBAL WARMING

If you could continually turn a lot of organic material into biochar, you could, over time, reverse the history of the last two hundred years...We can, literally, start sucking some of the carbon that our predecessors have poured into the atmosphere down through our weeds and stalks and stick it back in the ground. 
We can run the movie backward.  We can unmine some of the coal, undrill some of the oil. 
We can take at least pieces of the Earth and – this is something we haven’t done for quite a while – leave them Better Than We Found Them.” Bill McKibben, author, climate activist and founder of 350.org

CARBON SEQUESTRATION: TURNING BACK THE CLOCK ON GREEN HOUSE GASES

How Can Biochar Be Carbon-Negative?Fossil fuels are carbon-positive -- they add more carbon to the air. Ordinary biomass fuels are carbon neutral -- the carbon captured in the biomass by photosynthesis would have eventually returned to the atmosphere through natural processes -- burning plants for energy just speeds it up. Sustainable biochar systems can be carbon negative because they hold a substantial portion of the carbon in soil. The result is a net reduction of carbon dioxide in the atmosphere, as illustrated below. Biochar can hold carbon in the soil for hundreds and even thousands of years. Biochar also improves soil fertility, stimulating plant growth, which then consumes more CO2 in a feedback effect. And the energy generated as part of biochar production can displace carbonpositive energy from fossil fuels. Additional effects from adding biochar to soil can further reduce greenhouse gas emissions and enhance carbon storage in soil. These include: Biochar reduces the need for …

FOCUS ON SUSTAINABILITY: BIOCHAR

Biochar Is a Valuable Soil AmendmentBiochar is a 2,000 year-old practice that converts agricultural waste into a soil enhancer that can hold carbon, boost food security and discourage deforestation. The process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water. Biochar is found in soils around the world as a result of vegetation fires and historic soil management practices. Intensive study of biochar-rich dark earths in the Amazon (terra preta), has led to a wider appreciation of biochar’s unique properties as a soil enhancer. Biochar can be an important tool to increase food security and cropland diversity in areas with severely depleted soils, scarce organic resources, and inadequate water and chemical fertilizer supplies.

EL NMB PUBLICA MANUAL DE MEJORES PRACTICAS POST COSECHA

El ofrecer una sobresaliente calidad de mangos en el mercado para que los consumidores quieran comprar una y otra vez, requieren de un compromiso de producción con calidad por parte de cada uno de los productores y comercializadores involucrados en la producción y manejo del mango. 
El proyecto de calidad del mango ha identificado practicas de cosecha y postcosecha que pueden ser mejoradas, como son: una mejor determinación de la correcta madurez de cosecha, adecuado manejo de la temperatura – previo al tratamiento con agua caliente, posterior al tratamiento con agua caliente, previo a la exportación y durante la misma, así como en los centros de distribución en los Estados Unidos de Norteamérica – mejora en la clasificación y en el grado de los frutos, así como en el empaque y la paletización de los mangos, al igual que un mejor manejo en la exposición de los mangos en la tiendas de ventas al detalle.

USAID REPORT: ATAULFO MANGO IN CHIAPAS (2008)

EXECUTIVE SUMMARY 


This report examines the Ataulfo mango value chain in Chiapas, scanning across the chain and its various 
actors and market linkages to put observed dynamics in context and identify opportunities. 


The report pays particular attention to financial flows through the chain which inform other non-financial dynamics and highlight conditions and opportunities where financial services might help address challenges or 
allow for upgrading. 


The authors address financial issues within the broader analysis, rather than as a 
separate issue, or as an input at one level of the chain. 


Global mango consumption has grown steadily in recent years, both in producing and importing 
countries. 


Mexico has been one of the main producers and consumers of mango, and a leading exporter 
worldwide. 


Within an increasingly commoditized environment, the gold-colored Ataulfo mango from 
Chiapas (unlike the more common red or Florida varieties) has sustained a differentiated identity and a 
price premium…

ANALYSIS DE IRRADIACION UV-C SOBRE NIVELES ORAC EN TOMMY ATKINS

Se evaluó el efecto del tiempo de irradiación UV-C sobre los niveles de fenoles y flavonoides totales, β-caroteno, ácido ascórbico y capacidad antioxidante (ORAC) de mango ‘Tommy Atkins’ fresco cortado. 
El mango cortado se irradió por 0, 1, 3, 5, y 10 min previo almacenamiento a 5°C. 
Los frutos tratados por 10 min presentaron los mayores niveles de fenoles y flavonoides totales en comparación con el control (0 min) y el resto de los tratamientos.

EL USO DE LA PODA EN EL MANGO ATAULFO

La poda es una práctica indispensable para mantener la productividad en huertos de mango; sin embargo, esta labor es poco usual en Nayarit, México, y hasta el momento se desconoce cual es la intensidad más adecuada que permita controlar el tamaño del árbol y obtener rendimientos más altos.
 El objetivo de este estudio fue evaluar el efecto de la intensidad de poda sobre el vigor del árbol, producción y peso del fruto del mango ‘Ataulfo’.
 Se estudiaron las intensidades de poda de 50, 75 y 100 cm, más un testigo sin podar. El diseño experimental utilizado fue completamente al azar con 10 repeticiones.

CAMBIOS CLIMATICOS Y LOS EFECTOS EN LA FRUTICULTURA

En lo que va de 2011 la naturaleza ha dejado su huella con inundaciones, ciclones, sequías y fuertes lluvias. El 2010 fue uno de los que registró las más altas temperaturas. ¿Cómo han afectado o afectarán estas variaciones climáticas a la agricultura en las zonas al sur de la Línea del Ecuador? Expertos en el tema conversaron con Portal Frutícola. De acuerdo a Fernando Santibañez, profesor de Agroclimatología de la Universidad de Chile, los eventos climáticos que estamos experimentando en la actualidad son fenómenos graduales, en donde los cambios se irán observando lentamente, por lo tanto no es fácil identificar un impacto inmediato. A pesar de ello, indicó que en general se puede señalar que la variabilidad del clima ha aumentado, algo que ha quedado de manifiesto en el mundo ya que “variabilidad del clima en las últimas dos décadas es mucho más amplia que en las décadas anteriores”, lo que significa que “nos estamos enfrentando a eventos extremos con mucha mayor frecuencia”.  El prof…

It's a funny old world we live in - and not all that logical either.


 Just three months ago Presidents Mubarak, Ben Ali and Gadaffi were the toast of the town. Free world leaders wined, dined and holidayed with them. Pop stars serenaded them. 


International banks, hedge funds and property brokers waived money laundering regulations so their ill-gotten gains would be safely invested. Arms dealers from the democratic, freedom-loving West beat a trail to their bunkers flogging weapons of protesting mass destruction. Soccer clubs and prestigious universities snapped up their largesse.
