Book (stand-alone)Soil loss atlas of Malawi 2019
Also available in:
No results found.With over three-quarters of the country’s soils at risk, soil loss in Malawi represents a major threat to food security and nutrition, agricultural growth, the provision of ecosystem services and the achievement of the Sustainable Development Goals (SDGs). Since the Malawian economy is highly dependent on agriculture, soil loss is a significant hindrance to the overall economic development of the country. The Soil Loss Atlas of Malawi is part of an effort of the Government of Malawi (GoM) and its development partners to determine the major contributing factors to soil loss in Malawi and the most effective approaches to control it. This publication addresses the urgent need for updated data and information on soil loss rates in Malawi, which have not been reviewed since 1992. Furthermore, since soil loss is one of the monitoring indicators in the Agricultural Sector Wide Approach Program (ASWAp) adopted by the GoM and its development partners, there is also a need to develop a baseline soil loss rate to help with program indicator monitoring. Soil erosion is a natural or human-driven process where the top layers of soil are removed from their original location. In the context of agriculture, soil loss occurs when natural soil erosion is accelerated so that the soil is blown or washed away by agents such as water, wind and tillage. Soil loss is fuelled by agents of erosion (such as wind, runoff, gravity, etc.) and further influenced by factors such as unsustainable soil management, land use/cover management, topography, and soil type. Some of these factors are often (in)directly modified by human activities in ways that can increase or slow down the rate of soil loss process. The Soil Loss Atlas of Malawi builds a comprehensive picture of soils in the country by examining different types of soil loss and their drivers across the 27 districts of Malawi. The publication captures information on soil types, land cover and land use types, topography, mean annual rainfall, soil loss rates and soil nutrient loss rates. All of this data is mapped by district through photographic evidence, graphs and maps which effectively illustrate the scale and range of soil loss across the country. The Atlas also provides an overview of the topsoil loss trends between 2000 and 2014. The overall approach used for the development of this Atlas was the combination of modelling using the Soil Loss Estimation Model for Southern Africa (SLEMSA) model and validation by field measurements. The model provides a dynamic approach for estimating national topsoil loss using secondary data, development of a footprint history of topsoil loss rates in the past ten years, identification of potential drivers of soil loss in the country and capacity development of local staff to implement future soil loss assessment activities. The Soil Loss Atlas of Malawi is a useful resource for a variety of stakeholders including researchers, scientists, decision-makers, land managers, students and the general public. The publication provides a baseline for future monitoring of soil loss rates and trends in the country. It delivers key data and evidence which can inform targeted decision-making to tackle the issue of soil loss in Malawi. -
DocumentPineapple as alternate cropping to control soil erosion in Nepal 2011
Also available in:
No results found.Pineapple cultivation for household consumption is a traditional practice in the hills of Bengri in Nepal. However, the concept of cultivating pineapple in degraded land as a means of erosion control and alternative income source was itself a new practice adopted by local farmers. Cultivation of pineapple is appropriate in sloppy land, prone to erosion and even degraded lands. Before adopting the practice, maize was cultivated for household consumption. However, land management practices such as tillage were not properly adopted for maize cultivation and thus resulted in severe soil erosion. Due to unpredictable rain and longer droughts even during rainy season, maize cultivation is more risky. The objective of pineapple cultivation is to minimize soil erosion and promote the rehabilitation of degraded sloppy lands for additional income through pineapple cultivation. -
