Financing environmental sustainability for small landowners in Guatemala: the potential of the carbon banking approach
Presented at the 2012 Lincoln University Postgraduate
Conference, 28-29 August, 2012, Lincoln, New ZealandForest carbon is potentially an important income stream for small landowners in Guatemala
that would help to cease deforestation pressures. However, the temporary nature of
sequestered forest carbon, the risk of environmental disturbances releasing it, and the form of
international carbon markets affect the ability of small forest owners to participate in carbon
trading. To overcome these hurdles an annual carbon rental mechanism may be able to be
established through the carbon banking approach. Thus, this study attempts to explore the
potential of the carbon banking to include small forest owners into the carbon trading system
by providing annual payments for retaining forest. This paper reports the results of an
investigation into the stability of carbon pools formed by small forest owners in Guatemala
and the effect this has on requirements for applying carbon banking approach. The study
uses data on area burned annually in three eco-zones in Guatemala to estimate the risk of
loss of forest carbon due to fire. This information is used in Monte Carlo simulation to model
the risk-adjusted area of forest carbon available for leasing. The results show that only
96.35% of the forest carbon under contract from small owners in the wet zone is available for
leasing to the carbon market when adjusted for fire risk. The same adjustment for the
montane zone is 98.87% and for the dry zone is 97.13%. These percentages are used to
calculate the minimum differential between prices paid to small owners and what is charged
to carbon buyers

El aspecto bélico de Chaahk, el dios de la lluvia, en el Periodo Clásico maya
Chaahk, el dios de la lluvia y del rayo, fue uno de los dioses principales del Periodo Clásico maya (250-900 d.C). Dentro de los muchos aspectos que adquiere el dios se encuentra el relacionado con la guerra, que pudo verse impulsado por un dios guerrero de procedencia extranjera, Tlaloc. Desde finales del siglo VII, Chaahk es reconocido iconográficamente en contextos de enfrentamientos bĂ©licos. Tal como se aprecia en estelas, dinteles, pintura mural y cerámica, los gobernantes mayas incorporaron en su atavĂo bĂ©lico diferentes tocados con el rostro de Chaahk. En otras ocasiones se representan personificando al dios ante sus cautivos o en complejas narrativas bĂ©licas, como recogen los murales de Mulchic. El aspecto bĂ©lico de Chaahk permanece durante el Posclásico hasta la llegada de los españoles.The god of rain and thunder, Chaahk, was one of the more important deities of the Classic maya Period (250- 900 d.C). Among his many aspects is one related to war that was perhaps influenced by a foreign god, Tlaloc. From the end of the seven century, Chaahk can be recognized in iconographic contexts pertaining to warfare. Maya rulers depicted on stelas, lintels, ceramics, and in murals painting, incorporated Chaahk’s headdresses in their battle attire. On other occasions, as can be seen in the murals of Mulchic, personifications of the god are associated with captives or included in complex narratives related to war. These connections between Chaahk and armed conflict were maintained trough the Postclassic, and until the arrival of of the Spaniards
Animal behaviour: Shifting attention in order to disperse
New findings in the nematode Caenorhabditis elegans identify neuromodulation of behavioural responses to pheromones as a mechanism for regulating dispersal and foraging strategies
Use of Indicators to Evaluate Sustainability of Animal Production Systems
SUMMARY – Few indicators for sustainability are used in studying animal production systems. Sustainability of
these systems should be evaluated in a dynamic and multidisciplinary manner, and those indicators used should
allow for detecting the systems' most relevant properties, as well as the tendency of those systems to change.
Indicators proposed by FAO provide information regarding all attributes of sustainability, although in a manner
which is overly focused on technical and economic indicators at the expense of social and environmental factors.
In order to use these indicators to evaluate sustainability, it is necessary to: (i) integrate and reduce the number
of indicators, balancing them for all sustainability attributes; (ii) generate indicators which show system
sustainability in relation to the economic, environmental and social context; and (iii) design indicators which show
system evolution and the influence of this process on that system’s sustainability.RESUME – "Utilisation d'indicateurs pour évaluer la durabilité des systèmes de production animale". Les
indicateurs permettant de caractériser la durabilité des systèmes de production animale sont peu développés.
L'évaluation de la durabilité de ces systèmes doit être dynamique et multidisciplinaire et les indicateurs utilisés
doivent permettre de détecter les caractéristiques les plus importantes des systèmes et leur évolution. Les
indicateurs proposés par la FAO servent à informer sur tous les attributs liés à la durabilité, mais d’une façon non
équilibrée et trop centrée sur le système de production. Pour rendre possible l’utilisation des indicateurs FAO en
tant qu'Ă©valuateurs de la durabilitĂ© des systèmes, il conviendra de: (i) rĂ©duire le nombre d'indicateurs obtenus Ă
partir des donnĂ©es de l’exploitation, en cherchant un Ă©quilibre entre le nombre d’indicateurs qui correspondent Ă
chaque attribut de la durabilitĂ© ; (ii) gĂ©nĂ©rer des indicateurs reprĂ©sentatifs de la durabilitĂ© des systèmes liĂ©s Ă
l'environnement, aussi bien physique, économique que social ; et (iii) créer des indicateurs qui renseignent sur
l’évolution du système et de sa durabilité
