  • Impact of Water Mangement Activities on Rural Poverty Alleviation with Reference to Gash Scheme

Poverty alleviation is an essential issue for development process, and it is considered as one of UN millennium development goals (MDGs), there is worldwide agreement on the role of poverty alleviation as target of development policies and strategies particularly for country like Sudan, which has high poverty incidences in rural and urban areas. This research aimed at investigating the contribution of agricultural water management activities on rural poverty alleviation in Sudan: with reference to Gezira and Kassala states. The research depended on primary data collected by means of a questionnaire distributed to a sample contained 520 respondents in the study areas divided  into two categories members of water user associations and non members.  Also it measured the level of  water poverty  and predict the households who can escape poverty line according certain characteristics in both states. The results showed that, the level of water poverty in Kassala state is greater than Gezira state, which were estimated at 33 and 52, respectively. The results confirmed that in both study areas the farmers who are  members of water user associations have a better chance to escape poverty line than non members, the households headed by literate persons have a better chance to escape poverty than the households headed by illiterate persons. The households who have the main basic services like electricity and toilet have a better chance to escape poverty than those who have no services.

  • Factors Affecting Natural Regeneration and Distribution of trees Species in El-Nour Natural Forest Reserve

The present study was conducted in El-
Nour Natural Forest Reserve to assess the effects of
lightning, winds, illicit cutting and overgrazing as
unfavorable factors affecting the natural regeneration
in addition to tree species diversity in El-Nour Natural
Forest Reserve. For data collection and depending on
species and soil types more than 200 samples (205) were
taken covering the whole forest area. In each sample
plot, diameters at breast height over bark (dbh) were
measured for all mature trees by using tree caliper and
diameter tape for large trees (more than 95cm), and
total tree height (h) for the largest four trees by using
Suunto Clinometer. Damages by man, wind, lightening,
domestic animals, insects and diseases were also
monitored, counted and recorded in each sample plot.
The collected data were analyzed using Computer
Packages SPSS 16, past program and Microsoft Excel of
Office 2013. Average of diameter at breast height (dbh),
height (h), basal area (b) and volume (V) were
calculated as well as relative frequency (RF), relative
abundance (RA) and relative dominance (RD) for each
species. Scattered plots and trend graphs were fitted to
examine the effect of different selected agents on the
natural regeneration and distribution of tree species in
this forest. The occurrence of species within a sampled
area shown a considerable variation where relative
frequency change in descending order for the following
species, Acacia seyal var seyal, Combretum
hartmannianum, Terminalia laxiflora, Terminalia
brownii, Sterculia setigera, Anogeissus leiocarpus,
Sterculia africana and Acacia seyal var fistula
respectively. Man represents the most damaging agent
for most trees particularly those used for charcoal
production as it represent a source of income
generation. Lightening and winds damaged mainly
Combretum hartmannianum, Anogeissus leiocarpus,
Sterculia africana and Sterculia setigera as tallest trees
in the forest. The severity of damages caused by animal
and insects were less than that of former agent,
however, it alter the new regeneration in the forest
floor. One of the important new finding of the study
was the crown damage (new shoot removal) of Sterculia
setigera and Sterculia africana as fodder for domestic
animals. This new deviation may referred to the obvious
increase in domestic animals around the forest as well
as, the considerable numbers of nomads that passing
through the forest and sometime camping inside the
forest for many days and damaged it stock. The study
recommends that, intensive awareness program for
local people around the forest is necessary to reduce this
increasable pressure on the forest, as well the
participation of local people in forest activities. Also
some damaged compartments in the forest should be
fenced against domestic animals to facilitate the natural
regeneration.
