Summary
Sustainable agricultural practices (SAPs) adoption in Nigeria is influenced by climate variability and socioeconomic factors. Inorganic fertilizer use positively impacts crop productivity, highlighting the need for targeted agricultural policies and infrastructure development.
Area of Science:
- Agricultural Economics
- Sustainable Agriculture
- Climate Change Adaptation
Background:
- Increasing agricultural productivity is key to poverty reduction and sustainable development in rural areas.
- Adoption of sustainable agricultural practices (SAPs) is crucial for enhancing crop yields in a changing climate.
- This study investigates factors influencing the adoption of multiple SAPs and their productivity impacts in Nigeria.
Purpose of the Study:
- To examine the determinants of adoption and intensity of use for multiple SAPs (improved seeds, organic/inorganic fertilizers, legume intercropping).
- To assess the impact of SAP adoption on crop productivity.
- To understand the role of climate variability in SAP adoption decisions.
Main Methods:
- Utilized nationally representative, geo-referenced plot-level data from a Nigerian household survey.
- Employed multivariate and ordered probit models for adoption and intensity analysis.
- Applied instrumental variables approach to determine the impact of SAPs on productivity.
Main Results:
- Evidence of interdependences between different SAPs, with distinct factors influencing initial adoption versus intensity of use.
- Climate risks (temperature and rainfall variability) significantly affect SAP adoption and intensity.
- Access to extension services, education, off-farm activities, and wealth influence improved seed and inorganic fertilizer adoption; livestock and soil quality impact organic fertilizer use.
Conclusions:
- Results inform rural development policies to encourage multiple SAP adoption and boost crop production.
- Recommendations include strengthening extension services, promoting livelihood diversification, and developing climate-resilient crop varieties.
- Improved infrastructure for market and credit access is essential for farmers to adopt innovations.

01:25Multiple Regression
3.1K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

01:16What is Climate?
18.7K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

01:57Adaptations that Reduce Water Loss
25.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

01:24Factors Affecting Workability
97
The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...
