L’Évaluation économique de l'investissement dans la conservation des sols: Le cas des aménagements antiérosifs dans le bassin versant du lac Lagdo au Cameroun

Abstract

This article presents an analysis of the economic impact of erosion control facilities on farm operations in the watershed of Lake Lagdo in Cameroon. Over the past several decades, erosion control facilities, which are erosion control techniques, have been introduced in Cameroon. No assessment of the impacts of these on farm operations had yet been made. Drawing on data from a survey carried out in 2007 and 2008 and a switching regression model, the study concentrates on the effectiveness of the production factors of parcels of land with and without erosion control facilities. The comparison of the average crop yields of the operations in our sample that either adopted or did not adopt such facilities shows a significant difference, representing up to 10% of the value of the farm production. Proof of a positive selection bias is also found, indicating that the farms with above‐average crop yields are more likely to adopt erosion control facilities. Such facilities on the parcels of land also provide an advantage in terms of increasing the productivity of inputs. The analytical approach developed and the positive conclusion of the selection bias can be pertinent to assessing other soil conservation technologies promoted in the area.

Factors Affecting Adoption of Improved Crops by Rural Farmers in Niger

“…Moreover, our results suggest that the lack of education is a barrier to the adoption of improved crops. This result is consistent with the literature showing that the lack of education is a barrier to the adoption of agricultural technologies (Yong Ngondjeb et al, 2014;Roussy et al, 2015;Yabi et al, 2016;Issoufou et al, 2017). Public policy that promotes rural females' education can then encourage the adoption of improved crops.…”

“…Yet, recent studies in Africa report that food insecurity predominantly occurs in these countries especially in rural areas where agriculture is nearly the only source of livelihood (Bruno et al, 2013;FAO, 2015). Low agricultural productivity along with insufficient adoption of agricultural technologies such as improved crops continue to be an important barrier to get farmers out of poverty (Asfaw et al, 2011;Yong Ngondjeb et al, 2014;Issoufou et al, 2017).…”

Land tenure security and agricultural production in the rural areas of Burkina Faso

“…As a result, the negative effect on labor optimization may be misleading and influenced by the seed type used in a given crop year. Similar findings have been observed in numerous studies (Foning et al, 2014;Yong et al, 2014). Moreover, the judicious use of chemical inputs, with careful attention to dosage, can mitigate the risk of soil degradation and empower the soil to enhance agricultural production.…”

Effects of the Systematic Cluster Approach (SCA) and Rural Land Plans (RLPs) on Land Tenure Security for Agricultural Household: Insight from Benin (West Africa)

“…Continuous exploitation of the land leads, in the long term, to its degradation, with the corollary decrease in crop productivity. The decline in soil fertility is one of the major constraints on farms in terms of improving productivity in SSA, leading to strong demand for land and natural resources [29][30][31]. This is a source of population migration and land conflicts [32,33].…”
