DocumentMechanical soil conservation strategies to reduce soil erosion in Dominica 2014
Also available in:
No results found.In Dominica, natural disasters, such as storms and heavy rainfalls, regularly occur and have a direct impact on its agricultural sector. Therefore, mechanical soil conservation strategies are important management practices for crop production. These strategies use methodologies that include the use of bunds, terraces, waterways / drainage channels, and other structures, for example vegetative barriers, or stone / rock lines. Thereby, the structures are so installed as to break the force of winds or decrease the velocity of runoff to reduce soil erosion. Barriers can be constructed with live material, such as plants, dead material, such as rocks, or with a mixture of both materials. For an illustration of different on-farm erosion control strategies see the pictures attached to this practice. -
DocumentEnhancing drought resistance through Guinea grass mulching, Jamaica 2008
Also available in:
No results found.Guinea grass mulching is one of the local drought-mitigation strategies adopted in the low-rainfall areas of Jamaica. After the land preparation dried guinea grass is applied in a matted form over the area to be cultivated. This practice helps crop to survive during the dry season without having to recur to irrigation. Moreover, this technique enhances soil moisture for germinating seeds and allows for a better crop establishment and nutrient uptake. -
DocumentConservation agriculture for smallholder farmers in dryland areas, Kenya 2008
Also available in:
No results found.The Laikipia district, in the Rift Valley of Kenya, is located on the plateau north west of Mount Kenya. Due to its leeward position, the district is significantly dry, with aridity increasing from the slopes of the mountain to the dry lowlands. Inadequate rainfall and periods of drought have caused land degradation and soil erosion, affecting the productivity of agriculture and the livelihoods of smallholder farmers in these arid and semi-arid areas. Two Farmer Field Schools (FFS) established in the district introduced Conservation Agriculture (CA)principles and techniques which mitigated the impact of drought on farm production and on the environment. The goal of conservation agriculture is to maintain and improve crop yields and resilience against drought and other hazards, while at the same time protecting and stimulating the biological function of the soil.
