Synopsis (short abstract) 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.

No-Tillage Farming for Sustainable Land Management: Lessons from the 2000 Brazil Study Tour

In November 2000, the World Bank (WB) and the Brazilian Federation for Direct Planting into Crop Residue (FEBRAPDP) organized the third Study Tour on “Producer-Led Rural Organizations for Sustainable Land Management” (PRO-SLM), with particular emphasis on notillage systems (NT).1 The Study Tour followed a 10-day itinerary of over 1,000 km through Southern Brazil, covering Paraná and Santa Catarina States, two states which received WB support through land and micro-watershed management projects.< /p> This Paper presents the salient features of NT development in Southern Brazil and discusses the lessons learned with special reference to the scope for adapting and developing such production systems to Africa, in line with the Better Land Husbandry approach advocated through the Soil Fertility Initiative (SFI) in several African countries.In the context of this Paper, the term No-Tillage (NT) is used to describe the farming system studied in Brazil. NT has been an integral part of the ( micro)watershed management approach developed in the Southern Brazilian states of Paraná and Santa Catarina. NT was developed in response to continuously declining land productivity under “conventional” systems based on soil tillage. The underlying land management principles that led to the development of NT systems were to protect the soil surface from sealing by rainfall, to achieve and maintain an open internal soil structure, and to develop the means for safe disposal of any surface runoff t hat would nevertheless still occur. Consequently, the NT technical strategy was based on three essential farm practices, namely: (i) not tilling the soil; (ii) maintaining soil cover at all times; and (iii) using suitable crop rotations. All three practices must be followed if improved results are to be obtained in a sustainable fashion.

Assessing the Adoptability of Improved Crop Production Technologies by Small Farmers: the Case of Lesotho
Occasional Paper N. 6 - September 1996
1996

Also 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.
