Ethiopia

The potential of feed-food double-cropping was evaluated at Ginchi, Ethiopia, for two years with the objective of evaluating herbage yields of fodder crops and the subsequent effects on grain yields of chickpea and grass pea. Early maturing oat (79Ab382 (TX) (80SA95); 79CP84 (Coker SR. res) 80SA130; SRCP X 80Ab2806; C7512/SRCP X 80Ab 2252 and CO X SRCP X 80Ab2291) and common vetch (Acc. No. 2490; Acc. No. 2742) were selected and planted on lands reserved for chickpea/grass pea at the start of the main rainy season.

Land-use/land-cover (LULC) change and socioeconomic conditions of local community in the central highlands of Ethiopia

Ethiopia

This paper presents a case study of land-use/land-cover (LULC) changes from 1975 to 2014 in the central highlands of Ethiopia and traces out its impact on socioeconomic conditions of the local community in the study area. We used four time series Landsat satellite images, that is, Landsat MSS (1975), Landsat Thematic Mapper (1986), Enhanced Thematic Mapper (2000), and Landsat 8 OLI scenes (2014), to investigate the changes in LULC.

Using Changes in Agricultural Utility to Quantify Future Climate‐Induced Risk to Conservation

Journal Articles & Books
december, 2014

Much of the biodiversity‐related climate change impacts research has focused on the direct effects to species and ecosystems. Far less attention has been paid to the potential ecological consequences of human efforts to address the effects of climate change, which may equal or exceed the direct effects of climate change on biodiversity. One of the most significant human responses is likely to be mediated through changes in the agricultural utility of land.

Adoption of milk cooling technology among smallholder dairy farmers in Kenya

Kenya

Factors influencing adoption of milk cooling technology were studied with data for 90 smallholder dairy farmers who were randomly selected from seven dairy cooperative societies in Kiambu County, Kenya. Logistic regression identified the age of the household head, daily household milk consumption, freehold land ownership, fodder production area, number of female calves, cooperative membership and cooperative services as significant factors influencing farmers’ willingness to invest in milk cooling technology.

political ecology of territoriality: territorialities in farmer–herder relationships in Northern Ghana

Journal Articles & Books
december, 2014
Ghana

Fulani herder and farmer relationships in West Africa have always been troublesome as a result of farmers’ fundamental rejection of the herders’ inroads into their areas and also because of increased competition for available resources. In countries such as Ghana, local and even national campaigns have been launched to expel the herders but they persist.

Game changers for irrigated agriculture—do the right incentives exist?

Africa

Game changers to achieve sustainable intensification of agriculture are possible in the irrigation sector and they focus mainly on getting more with less. There is, however, still a long way to go to replicate, adapt and develop approaches to take such ideas to scale and increase productivity within existing agricultural water management contexts.

economic analysis of reforestation with a native tree species: the case of Vietnamese farmers

Journal Articles & Books

Vietnam

The area of degraded forests in Vietnam is substantial, currently about 3.1 million ha of which about 1.7 million ha (55� %) were granted to individual farms for reforestation. However, the result of farmers’ reforestation efforts is limited. We aimed to examine the financial return, technical efficiency, and factors determining reforestation with a native tree species (Canarium album) by farms. Our results showed that reforestation with C. album is less financially profitable than that with an exotic tree species (Acacia mangium) as the alternative land use option.

Farmers' (local and colonists) perceptions of environmental changes in the forest frontier of the upper Amazon, Peru

Journal Articles & Books

Peru

Amazon ecosystem degradation profoundly impacts life supporting processes of global importance such as climate regulation, as well as local conditions for livelihoods. In Peru's highland jungle, an expanding deforestation front of forest conversion to agriculture has vastly transformed the landscape. Small–scale farming, the main driver of forest degradation, and consequently household natural resource management affect ecosystem functionality. To investigate farmers' attitudes and priorities to services provided by the ecosystems (ES) we interviewed 51 farmers, both local and colonists.

Farmers’ perceptions of climate variability and barriers to adaptation: lessons learned from an exploratory study in Vietnam

Journal Articles & Books
december, 2014
Vietnam

Southeast Asian countries are confronting climate variability, challenging agricultural sustainability and rural livelihoods. However, little research effort has been devoted to exploring how farmers in those countries perceive climate variability and how the perceptions link to adaptive responses. This paper deploys information from three focus group discussions with 30 male farmers; and six in-depth interviews with one female and five male agricultural officers in the Mekong Delta, Vietnam.

Adoption and Frequency of Precision Soil Testing in Cotton Production

Journal Articles & Books
december, 2014

A 2009 survey of cotton farmers in twelve states collected information about the use of georeferenced precision soil testing (PST). Adoption of PST technology and the interval until retesting were examined with a Poisson hurdle regression. Survey data were calibrated using a post-stratification weighting protocol. Farming experience, farm size, land ownership, variable rate fertilizer management plans, and the use of soil electrical conductivity devices were correlated the with period until PST adopters retested soil.

Optimisation of the traditional land-use system in the Angolan highlands using linear programming

Journal Articles & Books
december, 2014

This study used linear programming (LP) to analyse land-use alternatives in the traditional Umbundu farming system in the Angolan central highlands. Farmers of the region have traditionally produced maize and pulses for subsistence and vegetables and timber as cash crops. Different pasture and forest fallow rotations are used along catena production sites. The system is labour-intensive and uses animal traction. LP problems were formulated and solved for a baseline land-use alternative, improved diet alternative and maximal timber production alternative.

Farmers' rights and food sovereignty: critical insights from India

Journal Articles & Books
december, 2014
India

Farmers' access to and rights over seeds are the very pillars of agriculture, and thus represent an essential component of food sovereignty. Three decades after the term farmers' rights was first coined, there now exists a broad consensus that this new category of rights is historically grounded and imperative in the current context of the expansion of intellectual property rights (IPRs) over plant varieties.
