Rwanda

STUDY SITE INFORMATION RWANDA

Study area Rwanda:

  • Rwanda is located in East Africa at the co-ordinates 2°00′S 30°0′E, bordering DR Congo, Tanzania, Uganda and Burundi.
  • Rwanda covers an area of 26,338 square kilometers, and it is ranked the world’s 149th-largest country.
  • Mean annual temperature for Rwanda is 19.1℃, with average monthly temperatures ranging between 19.5°C (September) and 18.5℃ (July).
  • Annual precipitation is 1,170.2 mm. Rainfall is experienced throughout the year in Rwanda, with most significant rainfall occurring from September to May.

Biogeography of Rwanda:

  • The country’s topography is mainly hilly giving it the name “Land of A Thousand Hills”
  • The highest point is Mount Karisimbi 4507 metres above sea level and the lowest point is the Rusizi River at 950 metres above sea level.
  • The country’s longest river is the Nyabarongo, which rises in the south-west, flows north, east, and southeast before merging with the Akanyaru to form the Kagera; the Kagera then flows due north along the eastern border with Tanzania. The Nyabarongo-Kagera eventually drains into Lake Victoria’
  • The country is divided into 5 provinces, namely, Eastern, Western, Northern, Southern provinces, and Kigali city
  • Rwanda’s administrative boundaries are divided into 30 districts

Agriculture in Rwanda:

  • Agriculture is a major economic sector for the people of Rwanda, employing about 70% of the total population.
  • 75% of Rwanda’s agricultural production comes from smallholder farmers.
  • Rwanda’s principal crops include coffee, pyrethrum, tea, flowers, beans, cassava banana, Irish potatoes, rice, wheat, and sugarcane, etc.
  • About 61% of Rwandan soil is suitable for agriculture as the soils are fertile.
  • Two planting seasons, Season A (short rain season), February to July, and Season B (long rain season), September to January.

Study region-Gatsibo district

  • The UPSCALE project is conducted in Eastern Province, Gastibo district, Nyagihanga sector

Population dynamics in Gatsibo district

  • Gatsibo District has a population density of 270 persons per square kilometer.
  • The total population increased from 283,456 in 2002 to 433,997 according to the 2012 National Census provisional results

Agriculture in Gatsibo district.

  • Gatsibo district is one of the Sustainable Agriculture Intensification and Food Security Project (SAIP) intervention sites across Rwanda.
  • Agriculture production and livestock is the principal economic activity in Gatsibo District.
  • 75.2% of the land is cultivated, fallow (4.7%), and pasture and non-agricultural land represent only 20.1%.
  • Main crop produced are cereals (maize and rice) representing 29.5% of cultivated land, followed by legumes and pulse at 28.5%, and bananas on 23.14%.
  • Livestock keeping is also an important source of income and food for agricultural households.
  • 69.7% of Households in the Gatsibo district own livestock mainly cows

General overview of demographics, and agriculture in the Nyagihanga sector

  • Area of 71.93 km²
  • Population of 28,812 inhabitants (2022 census)00.6/km² Population Density [2022] 1.8%
  • 6129, farming households
  • The average field size is 0.5 Ha
  • Main crops are maize, beans, bananas, coffee, sorghum, vegetables, soybeans, groundnuts,
  • Main Cropping practices in the area are mixed maize and beans, rotation of sorghum and beans, mixed beans and bananas, and rotation of maize and Irish potatoes.
  • Farmers keep livestock such as goats, pigs, and a few modern cows producing < 10 litres of milk and chickens. Very few traditional cows.

Key challenges facing the farmers in Nyagihanga (pests, erosion, water, land tenure, farm sizes)

  • Poor soil infiltration especially after heavy rain that happens in the months of March and April.
  • Pests; Stem borers, fall armyworm in cereal crops
  • Drought, resulting in livestock eating all grasses including desmodium and brachiria during the dry season.
  • Bad road to transport the harvest to the markets.
  • Many households are remote thus far from the marketplaces.
  • The landscape is highly mountainous, leading to frequent soil erosions, and mudslides.
  • Inadequate access to water especially for households living and cultivating up the mountains.
  • Limited farming areas, most of the farmers possess < ½ ha of land, thus limiting crop diversification, in turn restricting the household’s access to a balanced diet

Since when was push-pull introduced, how many farmers have been using/ trialling it, and what key challenges does it involve?

  • Push-pull was introduced towards the end of 2017 with ICIPE in collaboration with the Food for the Hungry organization and the Rwanda Agricultural Board.
  • In 2018, about 47 lead farmers were trained and became Trainers of Trainers (T.o.T)
  • The farmers embraced the technology in response to fighting stem borers and fall armyworm pests.
  • Desmodium and Brachiaria became popular amongst livestock farmers as well due to their highly nutritious components as farmers witnessed an increase in the quantity of milk from their cows
  • Currently, 750 farmers practicing push-pull technology in Nyagihanga as per the previous planting season in 2023.

Key challenges in push-pull technology

  • Some species of desmodium dry up quickly during the dry season,
  • The high cost of desmodium and brachiaria seeds became a barrier to the participants to scale the technology.
  • Travelling long to the big city to get desmodium and brachiaria seeds because they are not easily found in the local input stores; or agro-dealers.
  • Less number of livestock to help farmers get organic manure.
  • Crop rotation, forcing farmers to uproot the desmodium to plant edible intercrop
