Climate change is already talking its toll on biodiversity and the path humanity has taken of extensive mono crop  production with no regard to biodiversity has put  enormous strain in ecosystems around the globe, 
Plants are key players in any healthy biota. Atmospheric carbon  is transformed in to and organic carbon that is then incorporated to the food web. Humanity's  food security ,dependent on mono crops like soya, corn,wheat and rice is threatened by climate change and the availability of water sources for irrigation.  The crops mention above follow a C3 and C4 photosynthetic pathway which needs regular water availability. The norm with climate change are irregular rain patterns and an increase of global temperatures. We need to plan ahead.

Crassulacean Acid Metabolism plants  follow a different photosynthetic pathway one that evolved to be successful in the type of environment we are facing. Their stomata, tiny openings that allow the exchange of gases open an night when the temperatures are cooler, sequester the atmospheric carbon and store it as  malic acid, during the day when temperatures rise, they close the stomata minimizing water lose through perspiration and complete their photosynthetic cycle.
Mexico holds the most diverse concentration on cam-plants in the planet and humans here for millennia have been successful in incorporating them as food sources and in many other useful applications that need to be shared .

Permaculture design that incorporates the holistic management of grassland and cam-plants can help restore food security in conflict ridden arid regions around the globe. Same regions that are now triggering mass migrations to northern latitudes caused by the underlying consequence of loss of livelihood. 

The agave and cactus is are an important part of the xeric grasslands and scrublands ecosystems, they give nourishment and shelter to a myriad of organisms, help water retention and can be used as anchors to slow erosion, help soil formation and sequester carbon in environments that by nature have slow carbon cycles.

Governing sectors, nonprofits in hand with international agencies can coordinate affords to propagate and educate local farmers to incorporatee indigenous species of cam plants that con be used for sustainable fodder and human consumption in times of drought.

At the Federal and State level, Mexico has implemented programs to propagate cam-plants with a varied rate of success and the experience can be used as a precursor template to implement propagation programs around the globe, in fact many useful species of cam-plants can readily be micro-propagated at relatively low cost.

Below we added some links that can be useful to illustrate some State sponsored efforts to propagate agaves in Mexico. is an effort from the civil to bring awareness and incorporate Crassulacean Acid Metabolism plants to our food cycles to face our global warming paradigm. Link academics, farmers and the general public to generate effective propagation strategies.
