Hydrological impacts of urbanization of two catchments in Harare, Zimbabwe

Journal Articles & Books
Dezembro, 2014
Zimbabwe

By increased rural-urban migration in many African countries, the assessment of changes in catchment hydrologic responses due to urbanization is critical for water resource planning and management. This paper assesses hydrological impacts of urbanization on two medium-sized Zimbabwean catchments (Mukuvisi and Marimba) for which changes in land cover by urbanization were determined through Landsat Thematic Mapper (TM) images for the years 1986, 1994 and 2008. Impact assessments were done through hydrological modeling by a topographically driven rainfall-runoff model (TOPMODEL).

If we halt deforestation, will the world starve?

Journal Articles & Books
Dezembro, 2013

Making sure that we will continue to have enough to eat is at the heart of our shared ambitions to mitigate climate change. The United Nations Framework Convention on Climate Change (UNFCCC), the convention that has guided us through the highs and lows of 18 rounds of annual negotiations, states upfront that the reasons to stabilise emissions are threefold: to allow ecosystems to adapt naturally , to enable economic development to proceed in a sustainable manner and to ensure that food production is not threatened .

Impact of human activities and livestock on the African environment: An attempt to partition the pressure

Conference Papers & Reports
Dezembro, 1995

The impact of human endeavours on the environment in the struggle to eke out a living through crop and animal agriculture is examined in a holistic context. Analyses focus on all the sources of pressure that modify the vegetation cover of rural Africa, including the effects of fires and burning of biomass, fuel wood extraction and deforestation and land clearing.

Impact potentiel sur l'environnement

Journal Articles & Books
Dezembro, 1992

As the problems of impact assessement are rather intractable, a fairly simple dual approach is proposed. First the major components of environmental impact of current agricultural production systems in Africa (i.e. impact of cropping, livestock keeping, fuelwood and timber extraction and burning) are summarised. Second, "danger zones" in which current and future environmental impacts will be most severe and on which ILCA has focused its problem solving-research is identified.

Incentives +: how can REDD improve well-being in forest communities?

Policy Papers & Briefs
Dezembro, 2009

REDD initiatives are more likely to succeed if they build on the interests of forest communities and indigenous people. More attention is needed to the balance of incentives, benefits, rights and political participation across levels of decision making, interest groups and administration. Incentives can include payments or other benefits for good practices, developing alternative livelihoods, formalising land tenure and local resource rights and intensifying productivity on nonforest lands.
