The study established the factors that influence the use of cattle and chicken manure for managing soil fertility by surveying a random sample of 224 farm households in the Midlands of KwaZulu-Natal province, South Africa. The majority (87%) of the respondents are farming on communal land with an average farm size of 2.9 ha. Sixty-three% of the farmers in the sample used manure to manage soil fertility in their fields. Despite the fact that chicken manure was available in large quanties in the area, 54% of manure used was from cattle while chicken manure was used by 39% of the sample.

evil of sluits: A re-assessment of soil erosion in the Karoo of South Africa as portrayed in century-old sources

Deep, linear gullies are a common feature of the present landscape of the Karoo of South Africa, where they were known locally in the early twentieth century as ‘sluits’. Recent research has shown that many of these features are now stable and are no longer significant sediment sources, although they are efficient connectors in the landscape. Because most of the gully networks predate the first aerial photographs, little is known in the scientific literature about the timing of their formation.

Stakeholder and expert-guided scenarios for agriculture and landscape development in a groundwater protection area

Dinamarca

Nitrate and pesticide leaching led to the designation of groundwater protection zones in Denmark. The protective measures in these zones often clash with local interests in agriculture. Scenarios were used to evaluate the development of a groundwater protection zone in a farming area. Stakeholders are accorded strong influence on the scenarios. Scenario inputs comprised land cover, land use and farmers' plans and preferences, as registered in interviews with farmers. Scenarios were evaluated regarding the effect on nitrate leaching, extent of pesticide-free area and farm income.

Assessment of land degradation and its impact on crop production in the Dry Zone of Myanmar

Myanmar

Land degradation in terms of soil degradation is a major environmental issue posing threat to sustainable livelihood in the semi-arid region of Central Myanmar. However, the studies on soil degradation status and its impacts in this region are very scanty. The objective of this study was to determine the impact of land degradation on crop production both in terms of area and yield in the Dry Zone of Myanmar. Remote sensing and geographic information system-based modelling was utilized to assess and map soil erosion rates.

Understanding soil conservation decision of farmers in the gedeb watershed, ethiopia

The aim of this study was to investigate the main factors that influence smallholders' adoption decision of soil conservation measures in the Gedeb watershed. Data from 498 household heads who live in the three districts of the watershed were analysed using the binary logistic regression model. We find that farmers need adequate cash to invest in soil conservation measures. Moreover, farmers would be more encouraged to implement soil conservation measures when they have larger areas of cropland.

Conserving and promoting evenness: organic farming and fire‐based wildland management as case studies

Journal Articles & Books
Dezembro, 2012

Healthy ecosystems include many species (high richness) with similar abundances (high evenness). Thus, both aspects of biodiversity are worthy of conservation. Simultaneously conserving richness and evenness might be difficult, however, if, for example, the restoration of previously absent species to low densities brings a cost in reduced evenness. Using meta‐analysis, we searched for benefits to biodiversity following adoption of two common land‐management schemes: the implementation of organic practices by farmers and of controlled burning by natural‐land managers.

Evaluation of field wetlands for mitigation of diffuse pollution from agriculture: Sediment retention, cost and effectiveness

Journal Articles & Books
Dezembro, 2012

Diffuse pollution, and the contribution from agriculture in particular, has become increasingly important as pollution from point sources has been addressed by wastewater treatment. Land management approaches, such as construction of field wetlands, provide one group of mitigation options available to farmers. Although field wetlands are widely used for diffuse pollution control in temperate environments worldwide, there is a shortage of evidence for the effectiveness and viability of these mitigation options in the UK.

This report exemplifies the short, well-focuses formal survey emphasized in CIMMYT's on-farm research procedures. The survey was done in northern Veracruz, Mexico, where CIMMYT Maize Production Training carries out on-farm experiments. The report summarizes farmers' circumstances, describes management practices in maize, and draws conclusions for research opportunities.

Factors contributing to the marginalization of shifting cultivation in north-east India: micro-scale issues

Índia

Shifting cultivation, locally known as jhum, is the predominant agricultural practice for most communities inhabiting the uplands of north-east India. The negative impacts of the practice on forest and biological resources, soil erosion and land degradation have been a serious concern for several decades now to administrators and planners as well as to the academic community. In the current context, the practice has undergone drastic changes and has become increasingly unviable, gradually leading to the marginalization of farmers practising it.
