No Thumbnail AvailableDocumentAssessing the Adoptability of Improved Crop Production Technologies by Small Farmers: the Case of Lesotho
Occasional Paper N. 6 - September 1996
1996Also available in:
No results found.In Lesotho, some externally financed agricultural development projects have appeared particularly prone to failure. One reason may be that, when designed, projects have not been subjected to sufficiently rigorous analysis, particularly with regard to expected farmers' response to extension messages. The thesis of this paper is that the impact of high inter-annual fluctuations in crop yields (and of crop prices) on farmers' expectations plays an important role in producers' decision-making, and t hat this can be measured with sufficient approximation to assess the prospects for the successful introduction of "improved" cropping technologies in small farmers' communities. Stochastic Efficiency Analysis has been applied to the mountain areas of Lesotho, where natural conditions are particularly harsh, but it has wider applicability in project formulation. The paper is based on information gathered by an FAO Investment Centre mission, which visited the Districts of Thaba T'seka and Qacha's Nek in November 1995 on behalf of the Government of Lesotho and the International Fund for Agricultural Development to identify a Sustainable Mountain Agriculture Programme for possible IFAD financing.

Book (stand-alone)Recarbonizing global soils: A technical manual of recommended sustainable soil management
Volume 3 - Cropland, grassland, integrated systems and farming approaches - Practices overview
2021Also available in:
No results found.During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 3 includes a total of 49 practices that have a direct impact on SOC sequestration and maintenance in cropland, grassland, integrated systems and farming approaches. -
No Thumbnail AvailableDocumentParaguay: Financial and Economic Implications of No-tillage and Crop Rotations Compared to Conventional Cropping Systems
Occasional Paper N. 9 - July 1997
1997Also available in:
No results found.The introduction of soybeans to the southern and eastern parts of Paraguay in the early 1970s, followed by wheat in the mid-1970s, using conventional mechanised soil preparation practices with disc ploughs and harrows, initiated a process of widespread soil degradation and erosion. The technique of no-tillage was first used in Paraguay in the late 1970s. Following a slow start, its adoption by Paraguayan farmers gathered momentum increasing from 20,000 ha in 1991/92 to an impressive 250,000 ha i n 1995/96, accounting for about 19% of the land cultivated mechanically. In 1993, the Ministerio de Agricultura y Ganadeira (MAG) and the Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ) started a project aimed at adapting and further disseminating no-tillage in combination with rotations of both cash and green manure crops in the major grain producing departments of Paraguay. Since very little was known about the economics of these technologies in Paraguay, MAG in association with GTZ, initiated a detailed study which was guided by the FAO Investment Centre. In this paper, the findings of the study are summarised and discussed.
