2.1 Courte description de la Technologie

Définition de la Technologie:

Daily combination of livestock from all households into a single herd to drive to different designated portions of the communal grazing area so that grass may recover to replenish its food reserves before being regrazed some months later.

2.2 Description détaillée de la Technologie

Description:

The technology is currently being applied in communal as well as commercial farms of Namibia. It is particularly effective in areas with no fences and areas with high incidence of stock theft and predator losses. The technology aims to replace continuous grazing with planned grazing which allows recovery of grass plants in the growing season and prepares the soil and grass plants for the upcoming rainy season during the non growing season. In addition fixed carrying capacities are replaced by flexible stocking rates which track availability of forage. Two grazing plans are developed per year, one when perennial grasses are growing and one when they are dormant. The grazing plans may change depending on the season and unanticipated events such as fire. During the growing season a grazing plan is in place that ensures plants are not regrazed before they have recovered their root reserves and that animal performance is good. In the non growing season animal numbers are adjusted to ensure there is sufficient grass to last until rains are reliably expected. Several selections are planned for to ensure animal performance is good.

The grazing plans must take into account all factors that affect the livestock performance as well as the farmer. These factors include first rains, natural pans, animal performance, ensuring good quality forage for cows prior to bulling, poisonous plants, time for vaccinations, where the livestock should be when the farmer is on leave etc. Once the plan has been developed, the animals are herded using low stress handling techniques according to the plan to various parts of the farm or communal grazing area. Moving livestock by herding enables fire breaks to be created by deliberate overtrampling. Each night the livestock are brought back to a kraal where they are kept overnight. Watering of livestock can take place in the kraal at night or in the morning or in the field depending on water availability. This process is repeated day after day.

At the end of each growing season the amount of forage available to the current herd is estimated and animal numbers are adjusted to ‘ensure’ that rains will have been received whilst there is still sufficient forage for the livestock and leaving enough soil cover to feed the soil organisms and protect the soil. Deciding when the forager grown in the last growing season will run out must be done using a method that farmers relate to. Farmers may decide to meet and reach consensus on this based on their knowledge of the effectiveness of rainfall during this season and past experience. If it is decided that there is sufficient food to see the animals through until the next rains can be expected, then farmers have enough forage and may even be able to re-stock if there is a food excess. If however a forage shortage is expected, because too little grass was grown in the last growing season to see them through to the next rains, then de-stocking is needed. The severity of the forage shortage determines how many livestock can be carried on this land during this non-growing season. Again farmers can reach consensus on this. Deciding whose animals to sell and how many is always a thorny issue so farmers will always move excessive animals to other areas if possible or sell unproductive animals first if needed.

3.6 Mesures de GDT constituant la Technologie

Commentaires:

The technology does not involve a change in land use. The grazing plan means that livestock will only be on a particular piece of land twice in any given year (once in the growing season and once in the non growing season). The animal density is however high, leading to increased impact for a very short period.

3.7 Principaux types de dégradation des terres traités par la Technologie

4.1 Dessin technique de la Technologie

4.2 Spécification/ explications techniques du dessin technique

Schematic diagram of planned grazing of a growing season grazing plan. In this diagram grazing started in the bottom left hand camp, marked d1, and the livestock were grazed in this area for this day. The next day the herd of livestock were taken to the area marked d2 and grazed there. This continued until day 41 where the livestock are currently. If deviations from plan occur then the actual grazing map is marked according to what actually happened. This is the map that helps inform next year's grazing plan to avoid using certain camps at the same time of year. The degree of greenness in the diagram indicates the amount of recovery of grass since being grazed. It is lightest in the area just grazed, marked d40. By the time the herd reaches day 120, which has the darkest green indicating readiness to be re-grazed, then the grass in the area marked d1 was planned to have recovered sufficiently to be regrazed. This plan has a built in recovery period of 120 days. It is possible that growth rates are slower than expected and it may be necessary to reduce numbers of cattle in the herd to slow down the movement to ensure the desired recovery period is achieved.

Commentaires:

This is a key issue undergoing lobbying of government and the communal farmers union to establish through a consultative process legislation that enables grazing plans to be enforced from within and from outside. This is lacking at the moment.

6.7 Points forts/ avantages/ possibilités de la Technologie

Points forts/ avantages/ possibilités du point de vue de l'exploitant des terres
It is cost effective, real improvement is seen in grass production while livestock losses to predators are significantly reduced.
For absentee owners they can leave a manager and herders in place to get on with the work and this can be easily evaluated after time since animals wondering around leave evidence.
Livestock are better cared for as they used to be and a sense of community has been restored.

Points forts/ avantages/ possibilités du point de vue du compilateur ou d'une autre personne ressource clé
This is a viable and upscaleable technology for both communal and commercial farmland in Namibia and beyond.
It addresses the root cause of livestock related degradation and at a global scale can have a significant impact on mitigating climate change if all the degraded rangelands of the dry climates of the world are restored by using the principles embodied in this approach – which has been adopted in the National Rangeland Management Policy and Strategy. Moreover it can improve the quality of lives of millions of people who live in areas where livestock is the only viable land use.
This is a true triple bottom line technology that improves the resource base whilst increasing profits and enbables an improved quality of life of residents.

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

Faiblesses/ inconvénients/ risques du point de vue de l’exploitant des terres	Comment peuvent-ils être surmontés?
Herders are difficult to find, train and keep.	National level vocational training of herders is required.
Water infrastructure tends to result in overtrampling of the same routes.	The Directorate of Rural Water Supply should change its water specifications to include the provision of water for livestock – which can be cheap and effective.
Grass poaching takes place by neighbours and the majority will of people in an area is sometimes overrun by a small minority.	Farmers Unions must address these issues and get enforceable mechanisms in place for improved rangeland management.

Faiblesses/ inconvénients/ risques du point de vue du compilateur ou d'une autre personne ressource clé	Comment peuvent-ils être surmontés?
There is insufficient national buy-in from line ministries in terms of implementation to address many of the issues that have been raised.	Line ministries should support implementation to address these problems. Joint implementation, joint review and adaptation by government, unions, farmers and support providers will assist in solving many issues for resource base improvement.
