Impact of fertilizer use on weed management in conservation agriculture - a review

Décembre, 2013

Intensive farming has been adopted to produce large amounts of food grains and cash crops but environment is being deteriorated at alarming rate also. Increased use of fertilizers, pesticides, chemical growth regulators, machinery and poor management practices are accelerating environmental pollution, soil degradation, global warming, climatic change and food deterioration. Conservation agriculture offers a sustainable solution for all these problems most often. This review focuses the use of fertilizers in conservation agriculture and their impact on weed management.

Land accumulation dynamics in developing country agriculture

Décembre, 2013
Paraguay

Understanding land accumulation dynamics is relevant for policymakers interested in the economic effects of land inequality in developing country agriculture. This Working Paper explores and simultaneously tests the leading theories of microlevel land accumulation dynamics using unique panel data from Paraguay. The results suggest that farm growth varies systematically with farm size – a formal rejection of stochastic growth theories (that is, Gibrat's Law) – and that titled land area may have considerable infuence on land accumulation.

Adoption and extent of conservation agriculture practices among smallholder farmers in Malawi

Janvier, 2014
Malawi

Understanding factors affecting farmers’ adoption of improved technologies is critical to success of conservation agriculture (CA) program implementation. This study, which explored the factors that determine adoption and extent of farmers’ use of the three principles of CA (i.e., minimum soil disturbance, permanent soil cover with crop residues, and crop rotations), was conducted in 10 target communities in 8 extension planning areas in Malawi. The primary data was collected using structured questionnaires administered to individual households.

The global food system will experience an unprecedented combination of pressures over the next 40 years. Global population size will increase and competition for land, water and energy will intensify, while the effects of climate change will become increasingly apparent. Over this period, globalisation will continue, exposing the food system to novel economic and political pressures.This final report of the Foresight Global Food and Farming Futures Project argues that decisive action needs to take place now. The report identifies five considerable challenges ahead:

Vulnerability of arid and semi-arid regions to climate change: impacts and adaptive strategies

Décembre, 2008

This perspective document, part of the 16-paper series on water and climate change adaptation, focuses on the impacts and adaptive strategies in arid and semi-arid regions. The series reflect the central topic of the 5th World Water Forum, ‘climate change and adaptation’, where it was presented and discussed. The following risks posed by climate change to the water sector in arid regions are identified.

Livelihood diversification in Borana pastoral communities of Ethiopia - prospects and challenges

Éthiopie
Afrique sub-saharienne

This paper analyses the livelihoods of the Borana pastoral communities of Southern Oromiya in Ethiopia. It aims to inform policy makers, donors, and development practitioners about the best strategies for protecting and promoting sustainable livelihoods in the region. The study is based on survey data from participatory research carried out in three communities, as well as stakeholder consultations at district and regional levels.

The unresolved land reform debate: beyond state-led or market-led models

Décembre, 2005

Sharp inequalities in the distribution of land remains a major cause of extreme poverty in many developing countries. Some instances are the result of ownership patterns inherited from colonial administrations, others are linked to the struggle for economic prosperity in the post-independence era.Landlessness is therefore a significant problem for the rural poor. Most remedies that have been undertaken previously have not yielded positive results, as can be witnessed in Southern Africa today.

Agriculture and poverty in South Africa: can agriculture reduce poverty?

Afrique du Sud
Afrique sub-saharienne

Poverty and income inequality persist in South Africa despite efforts to eliminate them. Poverty is more pervasive in rural areas, particularly in the former homelands: the majority (65 percent) of the poor are found in rural areas and 78 percent of those likely to be chronically poor are also in rural areas.

Technologies for climate change mitigation: agriculture sector

Décembre, 2011

This guidebook by the United Nations Environment Programme (UNEP) Technology Needs Assessment (TNA) project describes crop and livestock management technologies and practices that contribute to climate change mitigation while improving crop productivity and reducing reliance on synthetic fertilizers. It focuses on six broad mitigation measures: cropland management; livestock management; manure/bio-solid management; bioenergy; grazing land management/pasture improvement; and the management of organic soils and restoration of degraded lands.
