New vegetation type map of India prepared using satellite remotesensing: Comparison with global vegetation maps and utilities
A seamless vegetation type map of India (scale 1: 50,000) prepared using medium-resolution IRS LISS-IIIimages is presented. The map was created using an on-screen visual interpretation technique and has anaccuracy of 90%, ...
Overcoming constraints of scaling: Critical and empirical perspectives on agricultural innovation scaling
Scaling is a ubiquitous concept in agricultural research in the global south as donors require
their research grantees to prove that their results can be scaled to impact upon the livelihoods
of a large number of beneficiaries. ...
What induced farmers to protect and manage on-farm tree natural regeneration in Nigerien Dryland?
During the second half of the 20th century the Sahel experienced one of the most striking shifts in climate known globally since instrumental records began to be kept-from anomalously abundant rains in the 1950's and 1960's ...
Understanding farm trajectories and development pathways Two decades of change in southern Mali
Institutional support for smallholders has been themotor for the expanding cotton production sector in southern
Mali since the 1970s. Smallholder farms exhibit diverse resource endowments and little is known on how ...
IMPROVING SEED GERMINATION OF FOUR SAVANNAWOODLAND SPECIES: EFFECTS OF FIRE-RELATED CUES AND PROLONGED SOAKING IN SULPHURIC ACID
A study was carried out to
investigate the effects of fire related cues (heat and smoke) and sulphuric acid treatments on the germination
of four woody savanna species, namely, Terminalia avicennioides, Piliostigma thonningii, ...
Ecosystem management can mitigate vegetation shifts induced byclimate change in West Africa
tThe welfare of people in the tropics and sub-tropics strongly depends on goods and services that savannaecosystems supply, such as food and livestock production, fuel wood, and climate regulation. Flows ofthese services ...
Comparison of aboveground vegetation and soil seed bank composition at sites of different grazing intensity around a savanna-woodland watering point in West Africa
Grazing removes a plant’s aboveground vegetative and reproductive tissues and can modify the soil seed bank, potentially impacting the restoration of preferred species. Knowledge about aboveground vegetation and species ...
Taking Profit from the Growing Use of Mobile Phone in Benin: A Contingent Valuation Approach for Market and Quality Information Access
An information systems-adapted Contingent Valuation survey was used to assess smallholder
farmers’ perceptions and the premium they are willing to pay (WTP) to get mobile phonebased
information on market prices and product ...
Gender in Agroforestry: Implications for Action-Research
Women in sub-Saharan Africa are major contributors
to the agricultural economy, but their lower access
than men to productive resources and opportunities,
limits them from achieving optimal production. This
paper gives a ...
Relationships between soil seed banks and above-ground vegetation along a disturbance gradient in the W National Park trans-boundary biosphere reserve, West Africa
Aims
Vegetation succession depends on the availability of suitable propagules
in the soils, thus knowledge of soil seed banks is essential
for formulating effective strategies for restoring the vegetation of
degraded sites. ...
