“…In contrast with previous studies (Abdoulaye and Sanders, ; Kassie et al ., ; Marenya and Barrett, ), the ownership of more livestock appears to have no impact on manure use, whose adoption was assumed to be facilitated by greater livestock assets. These findings support the idea that holding large livestock assets is not sufficient to promote the application of manure on crops (Kpadonou et al ., ). The ability to collect and transport animal manure is crucial, but the owners of large herds in the Sahel often undertake a long‐distance transhumance in the search for better grazing and water sources.…”

“…A very large body of this research was primarily focused on modern technologies, with much emphasis on the linkages between modern seeds and inorganic fertilizers. With increased interest in sustainable agricultural intensification, the most recent of these studies took a step forward by examining, in addition to the assessment of the adoption of a single modern technology, possible complementarities between the adoption of multiple agricultural technologies including water harvesting and conservation practices, soil fertilityenhancing technologies and agroforestry measures (Abay et al, 2017;Holden and Lunduka, 2012;Kassie et al, 2015;Kpadonou et al, 2017;Teklewold et al, 2013). Complementarity is defined as a positive linkage between pairs of activities, practices or technologies (van Biesebroeck, 2007).…”

Using a stepwise approach that combines several econometric methods, we assessed whether or not the adoption of modern seeds and the use of manure in cereal‐based systems are linked and, if so, what are the driving forces of the linkages between these two agricultural technologies under dry‐climate conditions in West Africa. We found complementary and substitutability linkages arising from jointness and endogeneity between the two technologies. Specifically, our findings reveal positive joint determination along with negative endogeneity between the two technologies indicating that, controlling for observable variables, both technologies are positively linked, but unobserved factors that affect one adoption decision are negatively correlated with the other. After controlling for jointness and endogeneity, we found significant complementarity linkages showing a significant positive effect of manure use on the adoption of modern seeds, which is also significantly and positively affected by the number of cash crops grown and remittances. The two technologies are reversely affected by schooling and the incidence of soil fertility problems within the farm, whereas the amount of healthy land has a positive effect on both. The study suggests that organic fertilizer can serve as an enabling factor for greater adoption of modern seeds, especially in less favourable climate areas, and strongly supports the argument behind the need to breed seeds suitable for the use of organic fertilizers. These findings provide avenues for re‐orientation of policies that promote the use of modern seeds in dryland areas in sub‐Saharan Africa, with a possibility of breeding and promoting them in packages with organic fertilizers to upscale their adoption.

“…Furthermore, the FGDs indicated that compared to other SLM practices, planting pits are one of the best and effective techniques in land rehabilitation. Previous scholarly empirical studies have concluded that planting pits can rehabilitate land within three to five years, while improved fallow will require seven to 10 years to achieve the same results (Schuler et al ., ; Kpadonou et al ., ).…”

Farmers in the Sahel have been acknowledged for reclaiming degraded lands and improving food security by ingeniously modifying traditional agroforestry, water, and soil management practices. Despite the advantages offered by this range of farming techniques, their adoption rate is influenced by several factors. Using multivariate probit models and a correlation coefficient, this article examines the factors influencing the adoption of five land management practices based on 220 household and 40 farm surveys in four adjacent rural communities in southern Burkina Faso. The model results indicate that household labor force, education of household head, land tenure security, livestock holding, and membership in farmers’ groups influence the adoption of zaï practice, composting, improved fallow, stone bunds, and live hedges. However, two of the surveyed factors ‐ number of farms and visit by agricultural extension staff during the 12 months prior to the survey ‐ were not significant. Furthermore, a significant correlation was found between different land management practices, e.g., the decision to practice zaï is significantly linked to that of live hedges and composting. Zaï practice and stone bunds are considered labor intensive, which explains their significant correlations with household labor force at the 1% and 5% levels of significance, respectively.

“…These techniques have largely restored the physical, organic and chemical properties of these degraded soils, thus improving crop yields by a factor of 8 to 16 [11], restoring the efficiency of degraded soils [12] and mainly increasing household incomes [13,14]. More than 70% of farmers have adopted these agricultural techniques [15,16,10]. It is in this context that the present study is initiated in the Tougou experimental site and aims at establishing a relationship between the soil water content available for the root zone and yields.…”

I S S N 2 3 4 7 -3487 V o l u m e 1 3 N u m b e r 1 0 J o u r n a l o f A d v a n c e s i n P h y s i c s | ABSTRACTThis study aims at assessing the relationship between soil water stock and the yield of agricultural practices in Tougou catchment located in northern Burkina Faso. It is a region that has experienced a significant and continuous degradation of its natural resources, especially soils, due to the climate variability and the rapid increase of the population. Areas allocated to subsistence agriculture are increasing at the expense of pastoral land. This degradation causes a change in processes and mechanisms that control ecological systems. In order to provide solutions to this issue, some agricultural practices have been implemented to improve crop yield. This is particularly the case of traditional techniques:"zaï", "stony line" and "half-moon", which can significantly improve the soil infiltration capacity and yield. Daily monitoring of soil moisture and pressure in experimental plots based on these agricultural practices show that half-moon and Zaï provided good yield with 2180kg / ha and 1070 kg / ha respectively compared to that of the control plot with about 480 kg/ha. These important yields are due in large part to the improvement of the retention capacity of these soils, thus giving to crops the necessary water need for their development even in drought periods Indexing terms/Keywordswater content, yield, agricultural practices, crop, sahelian climate, Tougou, Burkina Faso INTRODUCTIONFor several decades, the increasing of population pressure in arid zones located in the north and south of the Sahara has led to profound changes in the management and use of natural resources and agricultural land [1,2,3] These anthropogenic disturbances result in scarcity of natural vegetation, soil degradation (water and wind erosion), deterioration of the soil water regime, and a decrease in water efficiency for crop production. This has negatively affected agricultural activities in several Sahelian countries. Agricultural yields decline very significantly in this region as a result of climatic hazards and anthropogenic actions [4]. Indeed, according to the fourth report of the Intergovernmental Panel on Climate Change [5], rainfed crop yields could fall by 50% by 2020 in most of these countries. This is unfortunately the case for Burkina Faso where the situation is very pronounced in its Sahelian part. Indeed, according to the assessment provided in 1994 by the Institute for Environment and Agricultural Research of Burkina Faso (INERA) [6], about 90% of arable land in Burkina Faso Sahel is severely degraded, leading to a reduction in useful agricultural land per capita and marginal land use. In addition, the decline in annual rainfall in this region (more than 20%) since the end of the 1960s [7] has resulted in yield reduction of cereal production of about 16-20% [8]. In this region, the degradation of soil productivity results from the unbalance of organic and mineral matter induced by repeated fires, o...
