Fish farming and food security in Central Cameroon

World Region
,
Outcomes
, ,

Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha […]

Supporting adaptation by maintaining effective population sizes in agroforestry species

World Region
Outcomes
Interventions

In smallholder’s farms, evidence has suggested that effective population sizes are lower than they are in natural stands as a result of narrow sampling in seed collection, and ongoing reliance upon the same genetic material for future cultivation, as well as low individual densities, which reduces connectivity and associated pollination and seed dispersal. These effects […]

Shifting cultivation and agrobiodiversity in Vanuatu

World Region
Threat
Interventions
, , ,

In Vanuatu, farmers prefer to work numerous small fields in different locations and as a mechanism to cope with hurricane and pest damage. Shifting cultivation, a widespread cultivation system in the tropics, is also practiced and helps to maintain a high diversity of primary and subsidiary crops. 297 fields in 6 villages were measured and […]

On the South Java Coast, individuals switch between rice-farming, tree-crops and fishing to respond to dynamic seasonal and inter-annual variations in fish availability

Evaluating Social and Ecological Vulnerability of Coral Reef Fisheries to Climate Change

World Region

Kenya is at the frontline of climate change, and experienced unprecendented temperatures leading to widespread coral bleaching in the El-Nino events of 1998.  Furthermore, coastal Kenyans are highly dependent upon marine resources for livelihoods, although marine resources are subjected to a wide range of governance mechanisms ranging from community managed fishery enclosures to large govnernment […]

Forest Dependence and Rural Livelihoods in East Kalimantan

Interventions

The changing role of forests in people’s livelihoods in frontier areas is important from the perspective of poverty alleviation and forest conservation. This study explores the link between expanding economic opportunities, forest dependence, and welfare in 73 villages. Village economic options, forest cover, and land suitability for agriculture and forestry are determining factors of people’s […]

The Asian Development Bank and Bioversity’s International Coconut Genetic Resources Network (COGENT) partnered in an endeavour linking PGR conservation and poverty reduction in eight Asia Pacific countries to prove that “coconut farmers need not be poor”.  The project consisted of developing, deploying, testing and promoting promising coconut-based income-generating technologies in poor coconut growing communities to increase income and reduce […]

Product Diversification and Attitudes Toward Risk in Agricultural Production

Threat
Outcomes
Interventions

This study looks at small scale farmers in the Indian Semi-Arid Tropics and measures of farmer specific risk attitudes to estimate the opportunity costs of diversification. Through modeling, they try to estimate which farm production choices were positively correlated with a farmer’s level of risk aversion.    An index was created categorizing individuals into risk-averse classes, […]

In Senegal, the Rodale institute works with farmers groups to build on traditional knowledge to improve soil quality.  Approaches include integrating livestock and crop rotations into mixed farming systems, water harvesting systems like rock wall contour barriers, trees for windbreaks, and trenches to improve water capacity, and composting.  Through improvements to soil quality and water […]

Changing land management practices and vegetation on the Central Plateau of Burkina Faso

Threat
Outcomes
, , ,
Interventions
,

Cultivation of marginal lands, declining rainfall, and disappearing vegetation led to major declines in yield on the Central Plateau of Burkina Faso. Soil and water conservation techniques resulted in increases in millet and sorghum yields, and the restoration of forage on the landscape to manage livestock semi-intensively, and a rise in ground water tables.
