Synopsis (short abstract) This policy brief is based on a recent technical report on the microeconomic and macroeconomic impact of nutrient and soil loss in Malawi. Econometric estimates were used to evaluate the impacts, differentiated by segments of the national population and geographical areas. In the same manner, the demonstration of mitigation effects by specific agricultural practices offers valuable information for the design of policy recommendations aimed at maximizing the farmers’ profit when facing increasing phenomena of land degradation.

    Soil and nutrients loss in Malawi: an economic assessment 2018

    Soil loss is a major threat to agricultural development in Malawi, and the size of the agricultural sector in the Malawian economy renders it a major limitation to the overall economic development of the country. Soil loss reduces cultivable soil depth, but also takes away fertile soils from farmlands. The net effect is a loss of agricultural productivity, increased expenditure on fertilizers, and a general decline in profitability of crop production. The aim of the project is to analyse the economic impact of both soil and nutrient loss in Malawi with new country-representative data on soil loss and nutrient indicators collected through field surveys, merged with detailed climatic data and socio-economic information. It translates soil loss/nutrient loss into yield loss and estimates the economic impact of loss on agricultural production as a result of soil degradation and then, it identifies best practices to mitigate the soil loss phenomenon.

    Soil loss is a major threat to agricultural development in Malawi, and the size of the agricultural sector in the Malawian economy renders it a major limitation to the overall economic development of the country. Soil loss reduces cultivable soil depth, but also takes away fertile soils from farmlands. The net effect is a loss of agricultural productivity, increased expenditure on fertilizers, and a general decline in profitability of crop production. The study aimed to assess soil nutrient dynamics in Malawi for informing economic assessment of soil loss in the country. In order to assess changes in soil nutrient levels, the study reviewed past and present literature as well as soil data, and compared their results with those that were generated during the study.

    Economic evaluation of nutrient soil loss in Malawi - GLO/17/001//01/99 2019

    The economy of Malawi is highly driven by its agricultural sector. However, soil and nutrient loss are among the major impediments to sustained agricultural development in the country. Soil loss has previously been assessed at national level, and is considered a fundamental problem to be addressed in order to boost agriculture; while soil nutrient depletion is another type of soil degradation that requires special attention. Although it is important to assess these soil degradation types and understand their drivers and potential solutions, a key aspect for the Government of Malawi constitutes the understanding of the inherent costs of soil degradation to the national economy, especially from an agricultural perspective. Against this background, the project aimed to assess soil nutrient loss and perform an economic analysis of both soil loss and nutrient depletion in terms of its effects on the country’s Gross Domestic Product (GDP).
