Introduction
Avocado plantations in Mexico cover nearly 180,000 hectares. A large proportion of these had replaced the native forests. The hydrological impacts of this are unknown. We use the water budget approach, and register weather conditions with automated stations, rainfall partition components, soil water content in different locations and depths by means of TDR, FDR, and resistivity sensors, water consumption of forest plant species, and avocado trees by means of sap-flow TDP method.

Commercial fruit orchards are embedded in a landscape of native forest and diverse kinds of agroecosystems. The landscape structure of these systems is a major driver of biodiversity response. Generally, it is assumed that high levels of biodiversity occur in perennial systems largely due to their high structural complexity. However, little is know...

The genus Microcystis has been a worldwide attention factor for its ability to generate toxic algal blooms, by microcystins production. The main toxic risk derives from its tumor promoting activity, and its genotoxic capacity, as well as hepatic, gastroenteric, respiratory, dermal and inflammatory conditions. In Zirahuén lake the genus has develope...

In comparison to other forest types, tropical montane cloud forests (TMCF) are known to produce higher water yields. Even when TMCF hydrological functioning knowledge has increased in the last decade, there is a general lack of knowledge regarding the effects of land use change on infiltration and hydraulic properties for this type of forest. Here...

Montane cloud forests are a strategic forest type because of their water yield, nonetheless the soil water fluxes and hydrological behavior is largely unknown in these systems. Macropores can work as preferential flow pathways, but the conductivity of ma-cropores depends on 3D macropore system complexity and structure, which are strongly influenced...

Infiltration is the process in which water flows from the surface of a porous medium into its interior. Studying this process from a direct measurement perspective is highly demanding in terms of time and economic resources, because data recording must be done in time intervals of one to five minutes within lapses ranging from 0.5 to 4 hours. In th...

Characterizing hydraulic properties of different types of soils is of great importance for agricultural and geological studies. In situ measurement of soil hydraulic conductivity is a time-consuming task since data has to be recorded at fixed time intervals over a period of minutes or hours depending on the type of soil. Moreover, it is still neces...

I need to check the original Gardner 1958 Soil science paper. I used to have a hard copy (photocopy of the original paper), but, I can't find it any more.
I had not been able to find a PDF file for the paper yet. Any hint will be welcome.

La cuenca del lago de Zirahuén ha sufrido cambios en su condición natural a lo largo de los últimas tres décadas. La problemática de la cuenca del lago de Zirahuén es diversa y compleja. Por un lado, el incremento de la población y las descargas de aguas vertidas que esta genera, por otro, la modificación en los sistemas de producción agrícola y la intensificación de uso del suelo, además del cambio de uso del suelo y cobertura vegetal impactan la calidad del agua y la condición del vaso lacustre que tiene un volumen de 157 Mill m3, con una fluctuación anual de 12 Mill m3. Las descargas de aguas residuales de la cabecera municipal; Santa Clara y las poblaciones vecinas conectadas a la red de drenaje público no son tratadas en forma, ni cantidad suficiente con la infraestructura existente (planta de tratamiento de aguas residuales), esto, junto con los cambios en el escurrimiento superficial relacionados al cambio de uso del suelo favorecen la llegada de cargas elevadas de nutrimentos al lago de Zirahuén. Esta carga de nutrimentos ha llevado al lago a una condición mesotrófica. Así mismo, la elevada carga de nutrimentos, aunada al incremento de la temperatura, ha dado origen a florecimientos algales nocivos (cianofíceas), donde destacan organismos del género Microcystis spp. Estos florecimientos presentan un riesgo tóxico para la población ya que los organismos de este género producen toxinas (microcistinas) con capacidades neurotóxicas y hepatotóxicas. Las localidades mas vulnerables son aquellas que emplean el agua del lago para uso doméstico. Si bien las concentraciones de microcistina libre en el agua del lago detectadas fueron mínimas y para 2019 no presentaron un riesgo de toxicidad por ingesta o contacto directo. Estas toxinas son liberadas al morir las algas, esto último ocurre cuando el agua del lago es almacenada. En estos casos la concentración puede llegar hasta 3.9 g/L, muy por encima de lo recomendado por la organización mundial de la salud (OMS) en el agua de uso potable 1.0 g/L. De continuar el aprovechamiento directo del agua del lago para uso doméstico, y sin tratamiento adecuado para la potabilización y remoción de la microcistinas se espera un incremento en incidencias de afectaciones entéricas, otitis, así como hepatitis y posiblemente cáncer de hígado en la población expuesta, generando un grave problema de salud ambiental. De continuar con la tendencia actual, esto es, presencia de una elevada carga de nutrimentos en el lago asociada a: a) cambio de uso del suelo (deforestación), b) intensificación de uso del suelo (agricultura de frutales comerciales), c) tratamiento inadecuado e insuficiente de las aguas residuales, d) incremento de temperaturas por cambio climático, se esperan afectaciones directas en la salud de la población, así como afectaciones en el ecosistema y las especies acuáticas, por ejemplo en episodios de elevada mortandad de fauna acuática (peces). Esto podría afectar las actividades de pesca y turismo en la cuenca. Para revertir esta tendencia y reducir los impactos se proponen acciones en 8 ejes temáticos; uso y cobertura del suelo, agua, cambio climático, pesca, urbano y rural, educación, turismo e industria artesanal y aplicación de la leyes ambientales y normatividad. Dentro de estos ejes temáticos, acciones específicas que se consideran prioritarias son; a) Difusión de información verídica y científicamente sustentada para la población, b) programas de educación ambiental activa e integral basada en las condiciones específicas de la cuenca del lago de Zirahuén y los procesos que en esta ocurren, c) rehabilitación y mejora de la planta de tratamiento de aguas residuales existente, d) implementación de humedales para la remoción de nutrimentos, en especial fósforo y nitrógeno que llegan al lago, e) iniciativa de ley para limitar y restringir el uso de detergentes ricos en fosfatos en la cuenca del lago de Zirahuén y en el estado de Michoacán, f) implementación de un programa de recaudación efectiva que permita destinar recursos al funcionamiento e infraestructura para tratamiento de agua, g)programa efectivo de restauración de las condiciones ambientales de la cuenca, combatiendo la tala ilegal y el cambio de uso del suelo, h) estructuración e implementación de programas de monitoreo de calidad del agua y condiciones climáticas para detectar la ocurrencia de riesgos ambientales por florecimientos algales nocivos, i) actualización e implementación de los planes de desarrollo urbano municipal (Pátzcuaro y Salvador Escalante), j) actualización e implementación de los ordenamientos territoriales municipales.

Avocado is one of the fastest expanding cultures worldwide due to the high demand of the international markets. Mexico contributes with nearly one third to the global avocado market volume. In Mexico, this culture covers nearly 160,000 hectares, most of it in the central highlands. The ecohydrological impact of the replacement of native forests by avocado plantations is still unknown. The objective of this project is to provide sound information about avocado culture and native pine-oak and pine forest ecohydrology functioning and assess possible impacts of avocado culture expansion over the central Mexico highlands.
