Comentários:

Degradation of natural resources is taken into account in the management of water resources for pastoral land, and in the social approach prior to the development of the technology. For example, the locations of new sites for water supply structures should correspond to the capacity of the grazing land in terms of the period of access, the quantity of available resources and the integration of the area into a larger coherent landscape (especially the complementary relationship between the agropastoral zones in the south and the pastoral zones in the north). Several impact assessments and preliminary analyses have been carried out, including diagnoses of the pastoralist system with regard to the logistics of the movements of the herds, the social organisation related to the management of the areas, diagnoses of the grasslands, geophysical analyses, etc.

2.1 Descrição curta da tecnologia

Definição da tecnologia:

Securing the mobility of pastoralism through access to water sources (open wells and ponds in pastoral areas) and marking the livestock routes for transhumance: the case of the project Almy Al Afia in Chad and its consultative approach.

2.2 Descrição detalhada da tecnologia

Descrição:

Livestock keeping is one of the main economic resources in Chad (in support of 40% of the population and 18% of the GDP, Ministry of Livestock, General census). Pastoralism in the country is based on the mobility of herds in a context of irregular precipitation and variable forage resources in time and space, and benefits from complementary relationships between the different ecological zones. In Chad, herds are taken in regular movements with the seasons between the Sahelian and the Sudanese grazing areas. The former are nutritious but limited in quantity, while the latter are more abundant but of lower quality, and not accessible until the fields are cleared after the harvest (meta-evaluation of projects on pastoral water sources, IIED, 2013). Thus, pastoral livestock keeping is founded on mobility and rangeland management, and on building complementary relationships and trade around farming systems and cultivated areas. The pastoralist systems are economically competitive (limited use of food inputs), and occur in marginal land which is characterized by conflicts, riots and a high level of insecurity (Conference of N'Djamena: 'Pastoral livestock keeping: a sustainable contribution to development and security in Saharan and Sahelian regions'). In the pastoral zone of Chad, where access to water is limited, the management and control of water sources by a social group in practice also leads to the monitoring and control of the use of grazing land which becomes available when water is present.

The project Almy Al Afia (2004-2016), developed by a partnership between the AFD and the Ministry of Water of Chad, operated in two regions of central Chad. The project Almy Al Afia was based on an entry 'development', concurrently with a process to consult and involve joint agencies. The project has improved approaches of preceding initiatives: concerted action and identification of water sources derived from the dialogue between users and authorities, and development of the local management of infrastructures and rangeland. The latter counteracts an exclusively private management or, instead, an ineffective public management which promotes free access to water sources and grazing land.

The project has enabled to address the following points:
1. Support mobility in pastoralism by enhancing the access to water (rehabilitation and construction of 160 wells; digging of 31 ponds for pastoral use);
2. Maintain or build processes of consultation and restoring security (joint committees for consultation and prevention of conflicts during transhumance);
3. Promote the proper use of water supply structures, in time and space (rehabilitated and new wells, excavated ponds) by context-specific management (strengthening of traditional management systems) and encourage the maintenance of infrastructure.
The pastoral ponds should be constructed in locations of existing water sources (natural ponds in suitable places, i.e. with a clayey soil capable to retain water). The existing water source is enlarged and improved by rural engineering (enlargement of the surface, deepening).
The wells are rehabilitated. Most wells were constructed several decades ago and are severely damaged. The water supply structures all have different and complementary functions. The deep wells in the pastoral zone are generally used throughout the year, and are overexploited. The way in which these structures are managed is strongly anchored in the region. The District officer delegates the management to 'Heads of Wells'. These old wells, which are used day and night, are often in a poor condition. Rehabilitating degraded wells is given priority over digging new wells because of the substantial potential for conflict. The water supply structures in areas of dry forest are less old and smaller in number. These wells are less frequently used and function as an alternative water source when the traditional ponds, water reservoirs and wells have dried up. They allow to delay the movement of the herds towards grazing areas in the Sahelian zone.
The strip between these two zones is used for agropastoralism. Herds cannot remain there. Therefore the project has facilitated the movement of the herds to the zones further south. The pastoral ponds close to the livestock routes for the transhumance were created in a way to be easily used by the herders, but also to encourage short stays.
The approach was combined with consultation through joint committees for the prevention of conflicts, and at a later stage by marking of sections of the livestock routes for the transhumance. Many meetings were held with the users of the land management structures and policy makers, with the aim to identify and negotiate the target sites and to anticipate methods for the management and maintenance of the structures. This has enabled to maintain an atmosphere of social stability conducive to cooperation. Along almost 550 km of the livestock routes for the transhumance, sections were marked ('mourhals' in Chadian Arabic). The demarcation was not intended to enclose the herds in the livestock corridors (from which they can move freely outside the growing seasons for agricultural crops), but rather to implement the results of the consultations on the land use on the ground. The committees for the prevention of conflicts, which were supported by the project, also played a major role.

Comentários (tipos de projeto, etc.):

Projects on pastoral water resources like the project Almy Al Afia primarily focus on the development of water sources for pastoralism. The phases preceding the implementation are extremely important, because they are based on consultation and on the appreciation of local management systems. These phases include registration, selection of construction sites and the development of guidelines.

Comentários:

The context of pastoralism has taken the project approach to not ask compensation from users: if the users are never the same, then who should be charged? Who will collect the payments and manage the collected funds? In addition, most of the water supply structures are far from financial institutions, which causes problems in securing these funds. Therefore the users contribute in terms of day-to-day maintenance of structures, by mobilizing labour in particular.

Comentários:

The amount of financial support varied with the type of structure (more support for management and maintenance is needed for new structures than for rehabilitated structures) and with their location or specific problem (in the case of structures located in the agropastoral zones). Financial support to the markings of the livestock corridors was indirectly provided through the committees for the prevention and management of conflicts.

4.7 Fatores mais importantes que afetam os custos

Descreva os fatores mais determinantes que afetam os custos:

The costs of the constructions are highly dependent on their location (costs for the supply and disposal of equipment and materials), on the price of inputs (cement, etc.), and especially on the type of structure (depth of the wells, geological environment). The costs of the supply and disposal of equipment and materials include costs for the installation of the structures (water, cement, labour, machinery) on the construction sites (which are often far away from routes and towns), and costs for the disposal of the equipment after the construction is completed. The costs of supply and disposal can be significant with respect to the costs of the structure itself.

6.2 Impactos externos mostrados pela tecnologia

Especificar a avaliação dos impactos fora do local (medidas):

As explained above, in these zones with low rainfall and scarce natural water sources of temporary character (ponds), it is essential to combine the use of surface water with the use of water from deep permanent groundwater bodies. When they have the choice, herders almost exclusively choose sources with surface water (avoiding effort to extract the water). But when these sources run dry, they fall back on using wells (and deep groundwater). The rehabilitation of old wells and the construction of new wells in zones without wells contributes to increasing the availability of water.

6.4 Análise do custo-benefício

Como os benefícios se comparam aos custos de implantação (do ponto de vista dos usuários da terra)?

Como os benefícios se comparam aos custos recorrentes/de manutenção(do ponto de vista dos usuários da terra)?

Comentários:

The profitability is considered in relation to the number of animals/herds involved. The costs of construction and rehabilitation are certainly significant, but the water supply structures are used for thousands of animals (in case of the most heavily used wells); most animals drink every two days. Therefore the costs per head of livestock are limited. The wells are long lasting, and therefore the returns are positive in the short and the long term.

6.5 Adoção da tecnologia

• > 50%

Se disponível, determine a quantidade (número de unidades familiares e/ou área abordada):

The technology responds to a substantial need, but also corresponds to the capacity of land users to use and maintain the structures. The energy supply is provided by animal traction, and does not require external energy sources.

De todos aqueles que adotaram a Tecnologia, quantos o fizeram espontaneamente, ou seja, sem receber nenhum incentivo/ pagamento material?

• 91-100%

Comentários:

Access to water is such a large problem that it requires all the land users who enter the zone to be informed when a water supply structure is rehabilitated or constructed. The involvement of traditional leaders in the management of the structures, and the system of representatives of the traditional leadership in the various other zones (Khalifas) contributes to the spontaneous dissemination of the information.
