Poverty Prevalence and Agro-Ecology: Investigations

Interplay between agro-ecology and poverty prevalence amongst rural households

Mapping the global extent of soil constraints to crop growth plays an important role in developing strategies for agricultural production, environmental protection, and sustainable development at regional and global scales. The most widely used dataset is the Soil Fertility Capability Classification System (FCC) developed by Center for International Earth Science Information Network (CIESIN) and the Tropical Agriculture Program of the Earth Institute at Columbia University.

Yield Gap: Rainfed Maize

As a quick demonstration to estimate crop yield levels at regional-scale with various management assumptions, this post describes how crop systems models can be used to assess yield gap of rainfed maize due to the limited supply of soil nitrogen. This methodology can help researchers to find what is the most critical factor that limits crop yield productivity in a given environment condition and how to address the constraint.

Visualizing Soil Quality

As an appendix to the Harmonized World Soil Database (HWSD) v1.1, seven soil indicators have been published globally, at 5 arc-minute (10 km) resolution.

Effects of Soil Degradation

By modeling the decomposition of soil organic matter dynamics, crop systems models can simulate the effects of soil nutrient depletion under low-input extractive field management practices, as well as soil carbon sequestration under regenerative management practices.
