Changes in Allocation of Land Holdings, Production and Farm Size in the Rwandan Smallholder Sector Over the Period 1984/1990 to 2002
There have been major shifts/changes in land use patterns in Rwanda over the past twelve years. A few striking observations include: As a percentage of total farmland, cultivated land increased. The increase in cultivated land occurred at the expense of pasture and fallow and woodlot. The share of pasture and fallow decreased from 22% in 1990 to 14% in 2002 and woodlot decreased from 11% in 1990 to 7% in 2002. This trend of increasing cultivated land is apparent from the mid-eighties to today. These observations imply that land is being farmed much more intensively without much time to fallow and allow the soil to rejuvenate. Pasture and woodlot are also being cut down at the expense of cultivation. This has important potential implications for productivity as well as for the environment. Average calorie production per person per day in Rwanda is believed to have dropped significantly during the war period, and then has increased on average in 2002 to levels near those measured in 1984. The rural population dependent on the land has increased some 27% since 1984.food security, food policy, allocation of land, farm size, Rwanda, Land Economics/Use, Q18,
Farm-level Perspectives in Rwanda's Coffee Supply Chain Coordination Challenge
This synthesis shows the need to update and improve household-level information on Rwanda’s coffee sector, so that appropriate policies may be put into place to increase the level and diversity of smallholder and rural business income.food security, food policy, Rwanda, coffee, Agribusiness, Q18,
Commentaires sur les forces motrices des changements dans l'agriculture paysanne rwandaise 1990-2001: Agriculture et Elevage
The purpose of this policy synthesis is to document major shifts in output and provide hypotheses about the reasons behind the changes. The paper also documents troubling trends in the traditional agriculture sector, underscoring the need for improved agricultural input and output systems.food security, food policy, Rwanda, crops and livestock, Crop Production/Industries, Livestock Production/Industries, Q18,

Mitigation of poultry manure pollution in the Fraser Valley
Intensive poultry production in the lower Fraser Valley of British Columbia has
resulted in large quantities of poultry manure being spread on limited land space. This
manure is spread on land situated above the Abbotsford aquifer. Due to the high amount
of nitrogen and phosphorus present in poultry manure, there is a danger of these nutrients
leaching into the groundwater of the aquifer as nitrates. High levels of nitrates in drinking
water have been linked to various health hazards such as Methemoglobinaemia, stomach
cancer, and gastric cancer. The leaching problem is further compounded by the fact that
the region has porous soils, a high water table, and very high annual rainfall.
This problem was addressed by analyzing several dietary treatments having varying
levels of crude protein from a high of 25% CP (crude protein) to a low of 18% CP and
supplemented with the commercial amino acids L-LYS , DL-MET , L-THR, and L-TRY . A
linear programming model was used to determine the least cost diet from the various
dietary treatments. The most efficient dietary treatment was then identified by Manure
disposal options such as storage, land application, and transportation were also considered
along with their associated costs. Linear programming was used to identify the least cost
manure disposal strategy complying with British Columbia environmental regulations by
using a combination of the three options. The results from the two models above were
then combined to identify the optimum manure management strategy for a poultry farm in
the Fraser valley complying with environmental regulations.
The results indicate that diets containing lower levels of crude protein and
supplemented with amino acids costs less than those containing higher levels of crude protein. These diets perform better because the nitrogen in the protein is utilized more
efficiently thereby resulting in less nitrogen excretion in the manure. Manure that contains
low amounts of nitrogen costs less to dispose than that having high amounts of nitrogen.
Use of diets containing low levels of crude protein and supplementing them with
commercial amino acids can lower the costs of poultry farmers significantly while
complying with environmental regulations.Land and Food Systems, Faculty ofGraduat
