“…An improvement in rice productivity and production through producing and developing improved rice varieties is a vital strategy in addressing this shortfall. This is important in achieving a more comprehensive economic development, food security and poverty reduction in the country (Sheahan & Barrett, 2017; Shiferaw, Kassie, Jaleta, & Yirga, 2014; Wossen, Gatiso, & Kassie, 2019).…”

This study determines the impact of the adoption of improved rice varieties on household food security using farm‐level data from 900 households in Northern Ghana. We employed the doubly robust inverse probability weighted regression adjustment procedure complementary with a propensity score matching approach on two indicators of food security (household dietary diversity score and subjective food security). Across all the various estimation procedures, we observed consistent positive effects of the adoption of improved rice varieties on household food security. Policies that enhance diffusion and adoption of improved rice varieties should be encouraged to improve food security among farm households.

“…Soil conservation practices offer smallholder farmers an opportunity to improve soil fertility and sustainably increase yields while also conserving the environment, i.e., these are considered as climate-smart practices [12][13][14][15]. The adoption of agricultural technologies and management practices is widely recognized in improving the productivity and welfare of farmers, as exemplified in the Asian green revolution [16][17][18][19]. Despite the importance of agricultural technologies, particularly conservation practices, such as animal manure, crop residue retention, intercropping, and crop rotation for soil fertility management and climate-smart agriculture, farmers adoption decisions have not been adequately understood.…”

Understanding the Interdependence and Temporal Dynamics of Smallholders’ Adoption of Soil Conservation Practices: Evidence from Nigeria

et al. 2020

The adoption of soil conservation practices is widely recognized as essential in improving soil fertility and promoting climate-smart agriculture in general. Yet, smallholders’ adoption of soil conservation practices in Sub-Saharan Africa has not been adequately documented, especially in relation to the interdependence and temporal dynamics of adoption decisions. In this paper, we analyze the interdependence and temporal dynamics of smallholders’ adoption of soil conservation practices, such as animal manure, crop residue retention, intercropping, and crop rotation in northern Nigeria. We use data from two rounds of a farm-household panel survey among maize-based farming households and estimate econometric models, including pooled multivariate probit and random effects ordered probit. We found that there is a significant positive correlation between the soil conservation practices, suggesting that adoption decisions for these practices are interrelated and the practices are considered complements by the farmers. We found evidence of inter-temporal variability in the adoption of soil conservation practices, which suggests that some farmers do switch in and out of these practices and may likely explain the often-reported variability in maize yields. Also, we found that the farmers’ decisions to adopt soil conservation practices and the intensity of adoption are influenced by several factors, including farmer-, household-, farm-, institutional-, and biophysical-level factors. Yet, the factors that significantly influence the likelihood of adoption differ slightly from those that influence the intensity of adoption. Policy interventions to enhance the adoption intensity of conservation practices should strongly leverage important factors, such as contract farming, crop–livestock integration, and off-farm income diversification.

“…Many studies have shown that crop yield per N fertilizer use is relatively low in African countries [45,56,61,74,75]. Therefore, as has been realized in developed countries (Figure 9), developing countries need to increase the use of organic fertilizer, as this is the best alternative to offset the economic and environmental costs of using inorganic fertilizers [43,44,46,120]. Organic fertilizer (from animal and plant residues) is currently the most sustainable means of improving soil fertility and increasing food supply.…”

“…Many recent studies have reported that organic fertilizer significantly increased the soil pH and the concentrations of nitrogen, phosphorus, potassium, calcium, and magnesium when compared with inorganic fertilizer (46,72). On the contrary, some authors advise against the total eradication of inorganic fertilizer, especially in regions that have poor soils, including Africa, and recommend that organic fertilizer be supplemented with a minimal amount of inorganic fertilizer in order to achieve optimal production [44,46]. This has been supported by other scholars, who reported that the best proportion of fertilizer application for the African Savannah soils, for instance, is 1 organic to 3 inorganic fertilizers [49,50].…”

“…It is known that any method adopted to improve food security, including increasing yields, will have to consider resource limitations and ecosystem sensitivity to changes, especially those related to essential nutrients [42,43]. Therefore, sustainable approaches, such as rapidly increasing the use of organic fertilizer and decreasing the use of inorganic fertilizer, must be well developed [44][45][46]. The integration of organic manure and inorganic fertilizer will enhance crop production and environmental sustainability [47][48][49].…”

Subsidy as An Economic Instrument for Environmental Protection: A Case of Global Fertilizer Use

et al. 2021

Fertilizer subsidies may constitute a key economic tool with which to provide food for the growing population. Therefore, this work aimed to (i) assess the effectiveness of subsidized chemical (NPK) fertilizer use in food production by comparing the crop output between developed and developing regions and (ii) examine the benefits of organic fertilizer and the need for its use in developing regions such as Africa. Secondary data from 2000 to 2019 on global subsidized fertilizer use, crop production, income, and other agro-environmental parameters, such as climate and soil, were collected from the international databases of the World Bank, Food and Agriculture Organization (FAO), Forest Resources Assessment (FRA), National Aeronautics and Space Administration (NASA), and World Income Inequalities Database (WID), as well as countries’ national statistics. Data were analyzed using qualitative, quantitative, and geospatial software and techniques, such as SPSS, averages, multivariate analysis, and spatial analytical Geographic Information System (GIS) tools. The results reveal that the total global fertilizer use continuously increased from 79 million tonnes in 2000 to 125 million tonnes in 2019. Subsidized fertilizer use and crop production increased with countries’ economic status. For example, countries or regions with more economic resources tended to have higher fertilizer subsidies. More than 95% of North American and European countries recorded the highest total chemical fertilizer use, ranging from 855,160 to 18,224,035 kgha−1. In terms of organic fertilizer production, the percentage contribution in Africa relative to global production was only 2%, which was about 932,538 million tonnes below the production yield in North America. More organic fertilizer and less inorganic fertilizer should be encouraged instead of the total eradication of chemical fertilizers. This is especially applicable to developing countries, where food production is low due to poor soil and high food demand owing to a harsh environment and rapid population growth.
