Soil is an organic matter

From an early age my father taught my brothers and I to appreciate good soil. I can hear his instruction now as we cupped soil samples from our organic gardens and orchard in our hands, “feel the texture of it, can you smell the living organisms in the soil?” Good soil takes effort, and the rewards are far greater than production and turnover rate, good soil is the heart of our environment.

soil, climate change, and farmer's field experience

I visited a Himba village in Northern Namibia in 2018, and as a soil aware person I was struck with how degraded the landscape was from overgrazing. I asked our local guide about the state of the landscape. He explained that the land was typically like this at the end of their dry period except that the normal rain systems were not arriving as they had in the past. I pressed him about possible solutions, he shrugged his shoulders.

I thought about this experience as I read my ecological systems assigned readings this week. One author briefly mentioned the possibility of making topsoil. The first step to reclaiming soil is testing and evaluation. I discovered that there is a group of European scientists who are working with Namibian farmers on soil degradation problems similar to I had seen (Prudat, et al., 2018). They recognize that previous reclamation efforts had not included local farmer’s field experience. The renewed approach includes creating a soil testing system that is relevant to the regional farmers by incorporating their local soil classification system and by recognizing all of the actors involved in the farming activities. Finally, a bottom-up approach to developing a soil testing system that could lead to a long-term soil management policy in which all stakeholders are invested in.
