One of the key challenges of the 21st century is developing ways of producing sufficient amounts of food while protecting both environmental quality and the economic well-being of rural communities. Over the last half century, conventional approaches to crop production have relied heavily on manufactured fertilizers and pesticides to increase yields, but they have also degraded water quality and posed threats to human health and wildlife. Consequently, attention is now being directed toward the development of crop production systems with improved resource use efficiencies and more benign effects on the environment. Less attention has been paid to developing better methods of pest management, especially for weeds. Here we explore the potential benefits of diversifying cropping systems as a means of controlling weed population dynamics while simultaneously enhancing other desirable agroecosystem processes. We focus on crop rotation, an approach to cropping system diversification whereby different species are placed in the same field at different times.
With over 1,150 bat species worldwide – representing about twenty percent of the
biodiversity of all mammalian species – they carry out important ecological and agricultural
functions such pollination and dispersion of seeds. And while many tropical plant species
depend entirely on bats for the distribution of their seeds, it is true that in the tropics bats
can also be carriers of important diseases such as rabies, mokola, duvenhage, hendra or
nipah viruses. These are the ones we know of today, but some 40 years ago, all we knew
was about rabies. Is there more we should be doing?
This manual, “Investigating the role of bats in emerging zoonoses: Balancing ecology,
conservation and public health interests” is an introduction to the complex issues associated
with a One Health approach to understanding the biology and ecological importance of
bats, and the drivers of zoonotic disease emergence from bats to people. As an introduction,
this manual will provide a basis for understanding the need to balance natural resource
management, disease surveillance, prevention and control.
Agricultural extension in Uganda has undergone a number of transformations from regulatory 1920-
1956, advisory 1956-1963, advisory Education 1964-1971, dormancy 1972-1981, recovery 1982-
1999, Educational 1992-1996, participatory education 1997-1998, Decentralized Education 1997-
2001 and now Agricultural services under contract extension systems. Each of those up to 1997-
2001 had strengths to build on and weaknesses to change or improve, but had challenges of the
socio-economic and political environment. In addition there have been marked changes in the
concept of agriculture, which is increasingly seen in terms of commercial or farming for market with
emphasis on modernization of agriculture and use of participatory approaches in the process.
The dilemma is that the majority of the Ugandan farming community is predominately
peasantry/subsistence with a small fraction that can be regarded emergent farmers. Such
population may not respond sustainably to the now farmer owned contract extension system
including changing patterns of donors.
The paper examines a range of issues including training needs, identification of theses needs for
more relevant and responsive curricula, the key role of service provider’s development in creating
learning organizations, developing a strategy for linkages/ learning webs or net works and for more
sustainable donor interventions.
A Food and Agriculture Organization project is working to reduce food losses in the Republic of the Gambia, where two years of crop failures and soaring food prices have left more than half the country's population without enough food. In a world where in 1 in 7 people go hungry, roughly one third of global food production gets lost or wasted. But FAO and partners are working together on the Save Food Global Initiative on Food Loss and Waste Reduction. Because if we are to eradicate hunger, everybody involved in food supply chains -- from producers to consumers -- must change management practices, technologies and behavior.
