2.1 Courte description de la Technologie

Définition de la Technologie:

Agave forestry land reclamation system with native agaves, trees, shrubs and grasses planted through participatory action for a sustainable production of mezcal and other products in order to generate high incomes for farmers.

2.2 Description détaillée de la Technologie

Description:

Rehabilitation of degraded land is achieved using native agave (Agave inaequidens), trees and/or fruit trees, shrubs and grasses to create, over the medium-term (7-10 years), sustainable production of a traditional alcoholic drink (mezcal) made from agave and/or cosmetic and medicinal products, and/or fibres and/or fodder for cattle and/or wood. Between the agave plants, native vegetation is managed or planted for use as food, fodder and/or medicinal products. Depending on the slope and the level of land degradation, continuous planted rows of agave provide a ’green’ barrier that controls soil erosion and runoff.

Purpose of the Technology: The main purpose is to achieve sustainable land rehabilitation while generating a high income for the farmer. This allows reducing the amount of livestock and overgrazing, which is the main cause of soil erosion in this region. The production of mezcal gives local farmers high incomes. Trees, shrubs and grasses for medicinal uses, food, and fodder are complements of agave production and are processed mainly by women, while agave harvesting is a male activity. As it is very attractive financially, farmers stay in the communities instead of emigrating to cities or abroad. Biodiversity is preserved and increased using native plants (agaves, trees, shrubs, grasses). These plant associations are effective at controlling plant pests and diseases. Turning eroded into productive soil sequesters carbon and increases water availability as a result of the new soil cover.

Establishment / maintenance activities and inputs: Unlike most agave, Agave inaequidens reproduces from seed, which requires harvesting the seeds from native plants in the fields. One plant generates 80,000 seeds with a 90% success rate of germination, which is enough to cover 25 ha of agave forestry plantations set up to control soil erosion. After harvesting seeds from native agaves, trees and shrubs, seedlings and small plants are raised in a greenhouse and nursery managed by the owners and tenants of the land in the first year. At the beginning of the rainy season, these are planted in plots protected from cattle grazing for at least the first two years after planting. The harvesting activity for trees, shrubs and grasses is done annually, but for the agaves only once every 7 to 12 years depending on the degree of soil degradation. Some months before harvesting, the flower from the stem has to be cut. The leaves are then cut and left in the plot while the 50 kg heart of the agave (“piña”) is removed. Mezcal is produced from the heart and requires an average of three weeks and at least two men to process 25 agave plants (1.5 tonnes), which produces about 300 litres of mezcal.

Natural / human environment: Poverty levels in the area are medium to high and the income from agriculture accounts for only 10 to 20% of the total family budget. People, therefore, do not have time to install soil erosion protection systems in the fields. Cattle graze freely everywhere and the number of animals is increasing annually, which also increases soil erosion. Locals know how to produce mezcal, but they prefer to buy it from other people who take wild plants from their lands to process them. The proximity of the site to the Michoacán of Ocampo state capital and the recognition of the designation of origin for mezcal by the authorities will enhance its value for future production.

Commentaires:

Calculations are for the plantation of 200,000 plants (agaves and trees) which correspond to the numbers of plants for 100 ha in the agave forestry example presented here. The main portion of these plants is planted by the community on the own land; the rest is given or sold to other communities or private people. The lifetime of the greenhouse, nursery and fencing installations are around 10 years.

4.8 Facteurs les plus importants affectant les coûts

Décrivez les facteurs les plus importants affectant les coûts :

The most important factors determining the costs are: 1) the materials to build a greenhouse and the personal to take care of young plants; 2) the difficulties to make holes in the indurated soils, which takes time and efforts; and 3) the distance between the nursery and the field requires time and efforts (truck carrying the plants).

50 land user families have adopted the Technology with external material support

Comments on acceptance with external material support: The program just start in 2010, so it is too early to reduce the experience at few hectares!
As the land users belongs to the same comunity ("ejido"), formally, all the inhabitants are involved in some way by this experience

Comments on spontaneous adoption: As the program just started in 2010, it is impossible to have an exact overview of the results now (end of 2011). As the land users belong to the same community ("ejido"), formally, all the inhabitants are involved in some way

There is a strong trend towards spontaneous adoption of the Technology

Comments on adoption trend: It is too early to identify an adoption trend.

6.7 Points forts/ avantages/ possibilités de la Technologie

Points forts/ avantages/ possibilités du point de vue du compilateur ou d'une autre personne ressource clé
Remediation of degraded land turning it to a sustainable production generating very high incomes in the medium term How can they be sustained / enhanced? life will change drastically and not necessarily for the better. Transparency and communication regarding benefits and land use are necessary.
Project done in a participative way where different kind of stakeholders are involved: administrations, politics, scientists and people. How can they be sustained / enhanced? Maintain workshops dynamic between stakeholders, present results to other authorities and forum
Low-cost project but need to be funded and supported with technical and institutional advice to initiate the first cycle of the project. How can they be sustained / enhanced? Farmers can start to produce their mezcal from the wild agaves to sell them to wholesalers and use this money to pay for the project.
As a result of the economical benefits, young people will stay in the communities. How can they be sustained / enhanced? Involve the young to guarantee the future: develop the marketing, the diversification of the products, the quality of production, etc.
It will hopefully reduce the number of cattle, which are the main cause of soil erosion, as farmers lose interest in cattle raising. How can they be sustained / enhanced? Authorities need to monitor this and inform the farmers about the ecological impact of too much free cattle grazing.

6.8 Faiblesses/ inconvénients/ risques de la Technologie et moyens de les surmonter

Faiblesses/ inconvénients/ risques du point de vue du compilateur ou d'une autre personne ressource clé	Comment peuvent-ils être surmontés?
Obligation to find external funds to pay the first steps of the system (greenhouse, planting, etc.) due to the lack of incomes amongst farmers.	Involve all stakeholders in the project
Be sure that alcohol production will not be consummed in excess in the community	Control of the volume of the production, and the sufficiently high selling price should avoid "losing" the production at local scale
Risk that the benefits will be captured by few people	Transparency and stakeholder communication in accounting for the benefits
Marketing and selling the products	Authorities help the farmers to contact sellers. The formation of communities of producers, leading to products conforming to regulations that maintain good quality and provide certification.
Owing to the high incomes, life will change drastically and not necessarily for the better.
