Rain
associations
The Uganda Rainwater Harvesting Association (URWA) is a
national-level network to promote rainwater harvesting (RWH) to alleviate water and food
insecurity. Presently, it has about 104 members from various non-governmental
organisations, community-based organisations, research institutions, private companies,
government departments, funding agencies and individuals of Uganda. Similar associations
also exist in Ethiopia, Kenya and Tanzania - together constituting the Greater Horn of
Africa Rainwater Partnership.
URWA supports its members efforts to do RWH by focusing on
aspects like, the local institutional building and technical skill upgradation. Under
awareness creation, regular training programs are conducted in tank construction, crop
production and home economics. The association is also compiling a directory of all local
rainwater harvesters.
URWA has been able to establish a dialogue with state to
include RWH in the agenda. This breakthrough is the outcome of their persisting efforts.
With RELMA's financial assistance, URWA is moving ahead towards sustainable water
management practices.

Saving lives
Katsukunye about 170 kilometre (km) away from
Harare, Zimbabwe was well known for perennial water shortage. As the functioning of the
local school and clinic also started getting adversely affected, the Ministry of Health
and Child Welfare was on the verge of closing these down. However, the community's
endeavour to harness rainwater and evolve rules for its sustainable management is saving
several lives, everyday. About 120 people in the clinic and 700 students are its main
beneficiaries.
Earlier, absence of rainwater harvesting (RWH) system and adverse hydrogeological
features like rocky terrain and saline groundwater had intensified the crisis. Pregnant
women were the most affected, as the potable drinking water source was almost three km
away.
While searching for a solution, the local leadership approached Rainwater Harvesting
Association of Zimbabwe (RHAZ) for aid, which turned to one of its members Mvuramanzi
Trust. The Trust already operational in the region decided to take it up. A feasibility
study suggested the use of granite rocks for the construction of 192 square meters
catchment with 15 cubic meter storage tank. A smooth rock surface near the school was
selected as the viable site.
All this work was accomplished with community participation. About 300 households and
460 students provided labour. Interestingly, daytime meals were provided and shared by the
households, collectively. Katsukunye's local leaders supervised and mobilised resources,
while providing construction material. The project concluded in 2001 with significant
economic and environmental gains. A marked improvement has also been noted in the
childrens school performance. Cases of diarrhoea and unhygienic child delivery have
reduced considerably. The women now have more time to invest in productive ventures.
Adequate gully control measures has helped to control environmental degradation around the
granite rocks.

Diferent
pipes managing the growing demand |
The community has gone a step ahead. To avoid future
conflicts for the limited amount of water, water users committees have been formed. It
includes members from village, school and clinic. A demand management protocol was also
formulated to allocate water as per their requirement. RWH has proved to be a reliable
option in areas with serious shortages.

Drip
Irrigation: Options for smallholder farmers in eastern and southern AfricaIsaya
V Sijali
Sida's Regional Land Management Unit, Nairobi, 2001
It is a workable technical knowledge bank on small-scale drip irrigation systems.
Eloquently written, it gives a guideline for installing as well as managing drip in
sub-Saharan Africa. The layouts describing each technique are well marked. Information was
primarily collected by the agricultural extension workers. This 60-page manual is divided
into four well-structured chapters. It begins with a general review of the irrigation
potential of Africa. The effectiveness of the three most popular irrigation methods viz:
surface, sprinkler and localised (including drip, porous clay pots, porous clay pipes and
perforated plastic sheets) systems has been critically analysed. Chapter 2 explains the
environmental factors governing crop production and water requirements. Chapter 3
describes drip at a conceptual level.The last section focuses on three variations of
drip.The climatic, soil and water requirements of the selected crops have been calculated.
It concludes by providing the contacts of the drip system suppliers. |
