Place: burkina-faso, Africa
Sustainable management of natural resources Sustainable management of natural resources
Total Budget: € 1.650.000,00 | Period: From February 2003 To


The objective of the project is the regeneration of degraded, marginal land in collaboration with the local populations. Up to now 10500ha have been restored. The soils are worked with the special plough Delfino of the Vallerani System. Delfino creates micro basins in which the rain and runoff are collected and penetrate in depth boosting the development of roots, seeds of herbaceous species and the growth of healthy and vigorous trees. Biodiversity and the agro-forestry-pastoral production increase significantly ensuring long lasting food security and economic revenues to the population. These participate actively in the planning and implementation of the activities thus acquiring new knowledge and environmental responsibilities.
People’s and plant’s resilience increases concretely. Populations once again gain dignity and trust into the future, poverty and emigration reduce.
The project gives an important contribution to the fulfillment of the 3 UN Conventions and the Millennium Goals.

Centre for Development and Environment (CDE) / World Overview of Conservation Approaches and Technologies (WOCAT) - Switzerland

Initiative partner

WOCAT, the World Overview of Conservation Approaches and Technologies, was initiated in 1992 by a concerned group of soil and water conservation specialists who identified the need to counter prevailing pessimistic views of land degradation and to promote the documentation, assessment, and dissemination of land conservation and restoration practices. Recently, WOCAT has promoted an initiative for enhancing knowledge management and decision support for scaling up sustainable land management (SLM). WOCAT provides tools and methods that enable SLM specialists to identify priority areas and enable them to share their valuable resource-management knowledge. WOCAT helps its Members identify appropriate SLM technologies and approaches and support them in making decisions in the field, in various levels of planning, and in scaling up best practices. The method also helps to identify knowledge gaps and initiate research like cost-benefit, on-site and off-site impact and carbon benefit analysis

Improving and sustaining agro-sylvo-pastoral systems in dryland. These guarantee food security to the population diversifying and enhancing household income opportunities, thus contributing to the overall socio-economic development of the concerned populations particularly for the poorest and most vulnerable groups: women and children. It applies the Vallerani System (VS), the mechanization of a traditional water harvesting technology to create, using the special plow Delfino, micro-catchment systems allowing direct seeding of native plants (trees, shrubs, crops and herbs) in desertified, abandoned land in collaboration with the local population. Fast ploughing speed allows to regenerate big surfaces, thus concretely reducing desertification processes in the area. Food and fodder raise in quantity and quality with a continuous improvement of biodiversity and soil fertility. The VS and it's technology has already been tested and utilized on more than 120,000 ha in 13 countries.

Technology: the plow Delfino conceived by Dr Vallerani. By means of a wave motion creates crescent-shaped micro basins 5-6 meters long, 40-50 cm wide and deep. It digs 10-20 micro basins per minute. These are joined together by the trace of a ripper 2-3 m long, 50-60 cm deep. Breaking the soil compaction facilitates the growth of roots and penetration in depth of rainwater. Each micro basin collects even with very low rainfall (200-500mm) up to 1000 liters of water thus reducing water erosion. Water available to crops, pastures and plants increases 2 to 4 times compared to untilled soil. The micro basins also collect organic matter, seeds and fine soil carried by wind and water, which increase fertility, biodiversity and production. Tractor speed allows to process 1.5-2 ha/hour. The technology has been validated in researches and projects of FAO, ICARDA, CILSS, UNIDO, WOCAT, CIRAD, Cooperation of many European countries, Chinese government, Universities, ONG’s and private sector.

Delfino ready to start ploughing The ripper cracks and buffers the soil, easing and protecting the penetration of the ploughshare. This enters and exit the soil with a wave movement, obtained through a hydraulic system. Depth and length of the micro basin are adjustable. Due to wear this Delfino has been welded several times on site. The plow is complex but designed as easy as possible to use. A specific training for tractor drivers is part of the project.
Fast intervention with Delfino plough. A tractor with Delfino plow at work. The speed of work and the special shape and features of the plough cause the soil to split and crack allowing best water collection and infiltration in depth as well as facilitating roots growth. The speed of work allows to recover about 2 ha per hour. The field to be ploughed has been chosen among the hard and marginal ones, impossible to be worked with traditional tools and by man force alone.
Waiting for seeds and rain Degraded soil has been ploughed with the Delfino plow as far as the eye. The micro basins and the ripper furrows are well shaped, ready to receive the seeds. Since only 10 to 20% of the soil is tilled, in the rainy season the rain will fall directly, or flow from the hard soil between the lines (run off), filling the micro basins. This reduces erosion and evaporation, increases water infiltration in depth, allows the growth of seeds, plants and the development of healthy root systems.
Delfino3 special plough The Delfino3, the newest plough developed by Dr Venanzio Vallerani and produced by Nardi SpA, has special technical characteristics to maximize water harvesting, storage and penetration in depth into the soil. These are explained in a simple way in the video which also shows some of the application possibilities and results obtained with the Vallerani System in its whole.
Plowing the desert Delfino at work in the project The hard, arid soil cracks and buffers, getting ready to receive the rain and sustain the roots growth. Through a wave motion the Delfino plough creates each minute 10 to 20 micro basins connected by the trace of a ripper. Each one can collect up to 1000 l water. The fast speed of work allows to work 15-20 hectare per day, up to 3000ha per year.

../file-system/small/pdf ../file-system/small/pdf Technical sheet of Delfino3 plough The document itemizes the basic technical characteristics of the Delfino3 plough and it’s main differences to a standard plough. It explains with a simple language the characteristics and activities carried out by each individual part which make up the plough.

The project is implemented in the north east of Sahel region, Burkina Faso. A cartography of the vegetation cover shows that bare, lateritic, eroded soil is over 26%. Constant increase of human and animal pressure, delay or lack of rain, inadequacy of traditional agriculture systems and tools, woodcut, overgrazing, inhibit the regeneration of natural resources, triggering erosion and desertification processes. Economic insecurity is rampant, families depend on a single harvest, which must ensure the nutritional intake for an entire year. Animal breeding, the main activity, is deeply affected by the scarce quantity and quality of pasture. Emigration and seasonal migration, while causing the breakup of society’s structure, are often the only chance to survive. The general scarcity of pasture (and water) and the practice of seasonal transhumance also from Niger and Mali, can lead to social tensions.

Flock by Konsy prior to the start of the project, 2003 Soil degradation and desertification around the village of Konsy do not reduce the need of fodder for flocks and herds: the only “wealth and surviving warranty” for the local population. People will search pasture far from home or migrate. The amount of manure shows that the herds are numerous and at the same time that fertilize is not enough to reverse the ongoing degradation processes.
Forced seasonal or definitive abandon of their land During the dry season often man or entire families are forced to leave their home by the lack of food and fodder. This also affects the possibility for young’s to regularly attend school. The extensive recovery of degraded land for food production, pasture improvement and reforestation is vital to enhance and diversify productive activities, stabilize the society and enable an appropriate education to the younger generation.
Sahel view from Gorom hill The dry season has just begun. From the hill around Gorom Gorom in the north of Burkina Faso, the eye spaces on a bare, lateritic, degraded land with spare vegetation cover. Desertification processes are palpable and it becomes understandable how they affect the daily lives of the local population which are mainly shepherds and farmers. This is part of the project’s area.
The hut is closed due to the migration of the owner Emigration and seasonal migration, while causing the breakup of society’s structure, are often the only chance to survive. They are one of the reasons why children and young people cannot regularly attend school. The bare land in the background of the hut shows the main problem of the region: soil degradation and desertification. The door of the hut is protected especially from the entry of animals with thorns and logs.
Women pulling water from the hole In the Sahel water availability is very limited. The water supply is in the responsibility of girls and women. Depending on the season i.e. on its availability closer or farer away from home, every day they have to devote several hours to this task.

From an ecological point of view, the obtained average results, compared to the adjoining untilled soil and/or to traditional working methods, are: 350-500 resilient trees/ha; 2-4 times water availability; 5-30 times increase of quality and quantity of biomass production (pasture); 2-4 times increase of agricultural production; increase in  biodiversity; strong ground water recharging; great CO2 storage; wild animals recurrence; reduced water and wind soil erosion; recover of the physical and chemical properties of the soil. All leads to a general soil restoration and reversion of the ongoing degradation and desertification processes. From a social point of view this bears to reduced hunger, poverty, migration and social tensions. Disadvantaged people are trained, gain an environmental awareness, regain their dignity and confidence in the future leading to more individual initiative and activity. Children attend school regularly. All this also has its positive economic aspect.

Now fodder is assured 6 years after labour and sowing a dense, rich forest grows. The regeneration process is advancing and biodiversity (vegetal and animal) is highly increasing. Fodder is now assured also during the dry season.
Open air lesson Ehiha Ag Rali explains the project to the students, what we are doing and why, the importance of the fight agains desertification, the different seeds of the sown tree species, how to sow, how to treat and he recommends that they tell and transmit this knowledge also to their parents.
The big difference Short-term results: a few months after the rainy season the grass is still abundant in the part of the field worked with theVallerani System while very little is left on the unploughed soil. The choice of the fields to be ploughed is made together with the heads of the villages. The results management is entrusted to them.
field GPS survey Each field tilled with Delfino plough is defined with GPS. This enables to keep an objective and long-lasting track of each individual field. It also allows to carry out monitoring and scientific research with the satellite system, now highly expanding. The picture shows the map of the fields of the Deserto Verde project up to 2011.

In each named field (A,B,…Z) 3 plots (around 1ha each) of 10x10 micro basins have been monitored giving following results (right): 63% of the micro basin have at leas 1 tree with an average of 3 trees. 12079 plants have been counted on 20 hectares giving an average of 604/ha. In the yellow box the monitored tree species.

The direct beneficiaries are the poorest and most vulnerable families in the villages. The project involved about 18.000 agro-herders, of which at least 40% women (indirect beneficiaries estimated around 200.000). Due to environmental degradation over the past 50 years, agriculture is reduced and breeding has intensified. In recent decades, the herds have severely weakened and the number of animals is halved. The drop of milk production increases acute malnutrition, especially in children. Livestock are an important guarantee for food security as they can be sold when there is no more food nor cash
The specific needs on which we focus in the project are:
increase and restoration of the available land for agriculture and livestock
protection and enhancment of biodiversity
increase of quality and quantity of pasture, trees and water availability
resilience strengthening at local and regional level
dissemination of good practices of SLM involving local communities (up to now about 60)

Getting ready for the meeting People gathering in front of the municipality of Konsy for the meeting with the volunteers of Deserto Verde (DV). Konsy is the first village that asked DV to be part of their project. During the meeting theyl discuss together about the kind of intervention, choose the fields, talk about the different steps that have to be done and decide who does what. In the background: Konsy village.

2 social promoter of Reach Italia are mostly on the field involving the inhabitants of the villages, the biggest human resource. 6 tractor drivers and their assistants make the interventions on the soil. 1 driver, secretary, accountant and assistant accountant complete the operational team in Gorom. These are coordinated by a local coordinator and, from the headquarters in Ouagadougou, from the expatriate head of the Africa office and an accountant. They interact also with the other partners. The project team in Italy brings together consultants with different backgrounds, areas of expertise and levels of experience. The contribution of the inventor of VS Venanzio Vallerani and the technical consultant and trainer Alessandro Vallerani were crucial. Deserto Verde is mainly composed of forestry experts who have offered their expertise and generosity. The coordination of the work is managed by professionally trained personnel in the field of international cooperation.

All DV volunteers of 2007 From 2003 till 2014, the volunteers of the swiss association Deserto Verde (mostly forest experrts) have gone every year to Burkina Faso to follow up the project. Besides meeting with the operators of all levels of Reach Italia, they always met the people from the villages, discussed the interventions and sew with them the tilled fields, took trees and vegetation cover mesurements, GIS data, and controlled the results. Amadou is helping with translation and sharing of experiences and knowledge.
Everybody is coming for sowing The sowing day is a big event in every village and, from child to old, everybody (in 2012, 600 men and 360 women) comes to partecipate. They know that the results of the intervention are for them and that these can change their lives. That's why they have already prepared everything well. They have been collecting seeds and manure, carefully stored them, now they sow. After the rainy season they will observe how the plants grow close to their village day by day.
The REACH Italia staff on a field visit On the occasion of the inauguration of the new REACH Center of Gorom Gorom in 2013 the whole staff, locals and from the italian office, meets and makes a field visit to where the Delfino plough is just working.
Tractor drivers on the field The tractor drivers and their assistants have followed several technical trainings with the technical consultant and trainer Alessandro Vallerani. They learned how to operate with the tecnology, its maintainance, security aspects and all the basic knowledge to apply the VS to the best.
Lesson on desertification directly on the field The promoter Ehiha Ag Rali speaks about desertification with joung students by the field that have just been plough with Delfino.
Today is sowing day, Amadou teaches students how to sow. The promoter from Reach, Amadou Boureima explains to the pupils of the local school of Gagara how to sow the tree seeds in the furrows of Delfino plough. 3 seed for each micro basin, as the mill. The students listen careffully before starting sowing the field. French language.

The main difficulty is related with the technological aspect. The tractor and the Delfino plough are complex and their correct use is essential to obtain long lasting results and to prevent mechanical breakdowns. Over the years, a special training for tractor drivers has been done several times as the acquisition of all the skills and knowledge takes time.
At the start people were wary and only few villages wanted the intervention. A respectful and friendly relationship, local, good trained promoters, speaking on the obtained results and exchange visits have greatly augmented the request and the active participation in all phases.
The sowing was done with a special tube. Constant results control demonstrate that it could be done by hand so it became faster and  doable for everyone.
About the seed quality: some stock were punctured by insects or musty. The village people get now clear instructions on how to keep the seeds and the purchase is made by a competent person.

Discussing technical problem The scarce use to heavy equipment and to the observation of each technical detail can cause serious problems. Due to the difficulty of repairing conditions and of obtaining spare parts, these can compromise an entire campaign. An adeguate training and a careful maintenance of the technical unit are essential.
Everybody is getting ready for sowing The sowing day is a great celebration in which everyone participate with joy. We use local seeds and goat manure containing seeds. These recieved the nutrients, are protected from pests and predators and, being passed through the digestion process of the animals, will germinate at the best. The partecipation of the local people from the early stages of the project, makes them more involved and aware of their environnement and the rigenaration process of the land around their village.
Not correct micro basin The proper performance of the micro basins in relation to the characteristics of the soil is crucial. This tillage is not well done, the cam (the part of the plough giving the wave motion) is not working well and the result is a nearly strait and shallow line. This leads to scarce water retention, soil erosion, fast filling up of the basin and finally to scarce results.
Puntured seeds can’t germinate It is not easy to keep the insects away from the seeds! So it occurred that those collected by the local population or bought in the markets were punctured or musty. This compromised the germinability and so the possibility to obtain good results. Now special attention is given to this aspect by the promoters while speaking with the locals. Another good possibility is given by the collection of goats manure containing seeds.
The sowing technique At the beginning of the project a special tube was used for sowing. Sowing took a long time and some seeds such as Balanites were too big to pass through it. The seeds were bought in a tree nursery by Ouagadougou. Since 2007, as a result of various experiments we do hand sowing of local seeds and goat manure containing seeds. This requires much less time, can be done by everyone including children and costs are reduced.
Joung girl sowing A girl is concentrated in sowing the seeds she keeps in her shirt. She knows that her work is precious for her, for her village and for their surviving. So she is doing it at her best. French language.

The project applies direct sowing of seeds of native plants, i.e. already adapted to the local climate and environment. This allows each plant to grow following its own natural laws. The root system is deep and healthy boosting the restoration of the herbaceous and arboreal biodiversity (enriched 3 to 30 times both in quantity and quality) as well as the physical and chemical structure of the soil. Livestock graze and manure on the fields throughout the year contributing to continuous improvement of soil fertility. The VS allows to quickly regenerate big surfaces at a low cost, thus concretelly reducing desertification processes in the whole area.
“The animal biodiversity is largely enriched and we can also see the return of animals that we thought had disappeared forever like jackals, hyenas, wild guinea, hares, hedgehogs, squirrels, birds, reptiles, insects” (Konsy village chief, 2013). Hunting and sowing seeds of especially nutricious plants concur now to a healthier diet.

Detailed seeds list of DV At the beginning of the projects many seeds were bought by the nursery in Ouagadougou. In 2007 begun the collection of manure containing seeds which gives growing rates in up to 95% of the micro basins. Since 2012 all seeds are collected or bought around the projects area. Direct sowing of seeds of many species of local plants that are already adapted to the local climate and environment allows each plant to grow following its own natural laws and enhances biodiversity.
Faidherbia albida This well growing tree is the only local species that grows large enough to allow to make the mortars in which women crush the millet. It has become very rare because of the environmental degradation but is now growing again in the field of the project.
From the seed to a colourful mat The seeds collected and sown by the women grew well producing the raw material that skilled hands transform into beautiful mats. These will array the houses or can be sold at the market to secure an income.
Going to the market with the hay Grass is now abundant and someone starts cutting the hay and bringing it to the market. Its sale can be an important source of additional income. But the hay cut can be harmful to the young trees hidden by the grass: environmental survey and awareness, sharing old and new knowledge and training are part of the project.
Seed mix each one brings the seeds he collected. All seeds are mixed together and directly sown in the micro basins by the people of the villages. Most seeds are collected on place but to guarantee a reach biodiversity also where the degradation process is already severe and biodiversity poor, the seeds of some species are bought at the market or at the tree nursery. Some attention must be paid to their quality and germination rate
When plant dying is a good new Calatropis, a land degradation indicator dies. The death of this Calatropis plant indicates that the chemical and physical structure of the soil as well as vegetal biodiversity are restored and too reach for it to live. Villagers are now using its wood for cooking. Around it an Acacia Raddiana and rich herbaceous biodiversity. This triggers a virtuous circle whereby the animal biodiversity also increased considerably.
the natural root system The rainy season usually allow the seed to sprout. Once it is over, the seedling will grow up in a hostile environment, subjected to the high heat of the sun and with the humidity dropping quickly in depth. In order to survive in these conditions, in the first period of growth, many species develop a deep root system in relation to a reduced aerial part.

Among all the projects carried out with the VS the one described here has been the only desired and promoted by the civil society and also the most durable. This allowed a continuous improvement of all its aspects such as: the agronomic and forestry technique; the training of the technical staff and the social workers; the participatory approach; the relations with the authorities. The excellent experience and results achieved on all fronts as well as the constancy and commitment in their dissemination, have started a virtuous circle that has brought new donors to support the project itself but also the spread of the VS in new projects such as: Syno-Italian Cooperation project Afforestation in Inner Mongolia, China; FAO's Acacia project in 6 Sahel countries, an IFAD-UNIDO project in Marocco, an ICARDA project in Syria and Jordan; the ONG AGED starting a new project in Burkina Faso in 2013
