“…It has been argued that, with respect to land pressures arising from pine and eucalyptus tree planting, the agricultural intensity may increase or decrease with land pressure. Thus, induced intensification explains changes in agricultural intensity and by implication, changes in the technology and management of cultivation (Hirwa et al, 2022). It employs an understanding that the behaviour of smallholder farmers changes to any induced pressure on land (Zheng et al, 2022).…”

The study documents the trends and magnitude of tree plantation growth in the Kigezi Sub-region of South Western Uganda. In most developing countries, national governments have been promoting and supporting rural communities with tree-planting programs in the region. A trend analysis was used to determine the escalating tree plantation growth in the sub-region. Landsat (TM/ETM+) satellite images were used to capture the trends, and a survey was also used to obtain information on the distribution patterns of established tree plantations. A randomly selected sample of 389 tree plantation growers was surveyed. The research approaches adopted were to supplement and strengthen the findings and also to provide an opportunity for the researcher to understand in-depth how tree plantations grow in the rural livelihood economy. Recommendations from this study emphasise the strengthening of the existing policy reforms. Also, interventions to harness sustainable forestry management should be used to provide integrated benefits to all, ranging from safeguarding local livelihoods to protecting the biodiversity and ecosystems provided by forests and reducing rural poverty in the Kigezi sub-region

Over the last decade, flood events in the northern and western urban areas of Rwanda have increased due to anthropogenic activities and the effects of climate change. This study aims to use the Analytic Hierarchy Process (AHP) geospatial multi-criteria technique to identify flood susceptibility areas and exposed assets in Musanze City. Seven factors were considered such as Topographic Wetness Index (TWI), Rainfall, Land Use Land Cover (LULC), Slope, Soil Texture, River, and Digital Elevation Model (DEM) to create a flood susceptibility map with 5 classes (from very low to very high). To validate the final map, 26 GPS points were collected from areas with a history of flooding, and the susceptibility classes were compared. Results showed that 33% of the area (~2367 ha) was classified as high to very high risk, 23% (~1645 ha) was classified as moderate, and 44% (~3113 ha) was classified as low and very low susceptibility. The study also identified physical infrastructure and land use exposed in high and very high flooding areas, including 24 schools, 2 markets, and 1 health facility, 18668 km of roads, and 3400 buildings that are highly exposed to flooding. The applied methods in this study are useful for urban planners and government officials in developing flood mitigation policies, strategies, and plans.

“…Global warming and unsustainable management have influenced agricultural production in the dry land, leading to food insecurity and loss of biodiversity (Ahmed et al 2022;Hirwa et al 2022). The negative impact of climate change, particularly in the semi-arid regions of the world, is due to the rapid melting of glaciers and prolonged droughts, leading to significant declines in agricultural development (Ullah et al 2021).…”

Climate change is shifting rainfall patterns, air temperature, river flows, and sea levels globally, resulting in changes in ground and surface water quality due to salinization, especially in arid and semiarid regions. During dry periods, the main water quality issue is a high quantity of salt in the water. Whilst water with fewer than 3,000 mg/L total salts is beneficial to all livestock species, tolerances vary greatly based on conditions and circumstances. Understanding the normal salt tolerance of animals without harming their production and health is important for sustainable livestock production, especially in dry areas. Understanding the normal salt tolerance of animals without harming their production and health is important for sustainable livestock production, especially in dry areas. Thus, this review examined the physiological, behavioral, hematological, and biochemical responses of sheep and goats in dryland areas under climate change scenarios. Despite changes in physiological, blood, biochemical, feed and water intake, sheep and goats adapt to salinity levels to drinking water in arid environments. Adaptable and native breeds are known to be more tolerant of saline water than selected exotic breeds. Small ruminants experience a decrease in food intake and weight, a decrease in breathing rate, and an increase in blood metabolite concentration when the salt in their drinking water increases. The concept that native and adapted small ruminant breeds can withstand high water salinity is gaining popularity in scientific research worldwide. More research is needed to investigate the water tolerance capabilities of adapted breeds, especially in dry and water-saline regions affected by climate change.
