Abstract

Char is any accretion in a river course that extends or establishes new land. A well-planned integrated land-use system combining woody perennials (agroforestry) can ensure sustainable, environmentally friendly climate resilience land-use systems and livelihood options on charland. To date, no systemic investigation of charland land agroforestry has been undertaken. A comprehensive study of the potential of agroforestry systems in charland areas was conducted using qualitative and quantitative methodologies. Two methods were employed: structured questionnaire interviews and botanical surveys. Findings revealed that considerable variation exists in both charland and mainland areas in terms of socio-demographic characteristics. Both tree and agroforestry knowledge of mainland farmers is greater than that of charland farmers. Charland dwellers sell almost all their farm products, while most mainland farmers consume their products. Agroforestry-related communication between extension workers and farmers is limited in both ecosystems. However, farmer interaction with extension workers is far less common in charland areas. Mainland farmers are satisfied with their homestead production systems, whereas cha land farmers face huge problems with the free grazing of cattle and goats. Mainland farmers think quality planting materials and fencing systems are key issues. Leafy short-rotation vegetables and climbing vegetables are more common in charlands. Other common marketable vegetables are tomato, brinjal, carrot, cauliflower, and cabbage. All fruit trees common on charland are more frequently found in the mainland areas. In the case of timber, eucalyptus (Eucalyptus camaldulensis) is more common on charland, whereas mahogany (Swietenia macrophylla) frequency is higher in the mainland. Medicinal trees are uncommon in both ecosystems except for neem (Azadirachta indica). Through proper training and motivation of farmers, there is a vast scope to increase tree and vegetable diversity in charland farms.

Abstract

The degree of soil erosion depends on the erodibility of the soil and the erosive agents. The primary energy source for soil detachment and transport in water erosion processes is rain and runoff. In the northwest region of Somalia, we thoroughly evaluated the aridity and erosivity indices. This study, aridity and erosivity indices and arid periods of Woqoyi Galbeed were assessed. In the CORINE methodology, four parameters are used to evaluate the potential and actual soil erosion risks: Soil erodibility, erosivity, topography (slope), and land cover. Fournier Precipitation Index and Bagnouls-Gaussen Drought Index were calculated using rainfall data that were measured from 2011–2019 in the region and temperature data that were taken from 50 meteorological stations. The study illustrates that most of the study area is under moderate erosion risk. Although a small portion of the Southern parts of the study areas have high erosion risk, these areas have low erosion risk due to the very steep slope. The Erosivity Index quantifies the effect of rainfall impact and also reflects the amount and rate of runoff likely to be associated with precipitation events. Evaluating the result of MFI and BGI overlaid shows that there is low erosivity risk in the northern part of the country. It includes the Bossaso, Aburin, Dararweyne, Burco, Xudun and Iskushuban weather stations. It is covering the area of 204978, 65km2, which represents 32.14% of the study area. This indicates that Northern part of the country, annual rainfall is low, whereas some areas like Erigabo and gebiley are relatively moderate in the MFI.
