Soil fertility decline is a major constraint to crop productivity on smallholder farms in Africa.
Faced with an overabundant elephant population amid the difficult context of the land reform programme in Zimbabwe, SavÃ© Valley Conservancy (SVC) applied for an annual management quota of 60 animals in 2008 with the objectives of controlling an increasing population, attracting goodwill from the surrounding rural communities by providing a protein source and reducing the illegal bushmeat trade
Agriculture is one of the biggest sources of greenhouse gases. Rice production has been identified as one of the major sources of greenhouse gases, especially methane. However, data on the contributions of rice towards greenhouse gas emissions in tropical Africa are limited.
Multipurpose mosaic (“ecoagriculture”) landscapes can serve the purpose of land sharing to combine objectives of agricultural production and biodiversity conservation. Rewarding the people who shape and maintain those landscapes could act as a mechanism to generate added-value representing an indirect payment for ecosystem services.
Adequate operation and maintenance (O&M) of irrigation infrastructure sustains irrigation scheme facilities, reduces repair costs, helps the system last longer, and keeps irrigation efficiency at design levels.
The constitution was drafted by a Parliamentary Select Committee and approved by Parliament before being signed by President Mugabe.
The knowledge of runoff discharged by a catchment at its outlet is important for water accounting and water allocation to competing uses. Runoff generated by a catchment is important in determining the catchment water balance, estimating pollutant loads, and quantifying sediment yield and delivery ratio.
An evaluation of available opportunities to revive irrigation on a long abandoned irrigation scheme in a dry region of Zimbabwe is presented by assessing water availability at catchment level.
A preoccupation with the idea of land as a productive asset continues to dominate donor policy prescriptions imposed on poor nations of the world. The presumption is that a view of land as a productive asset implies security which then induces investment and improvements in agricultural productivity.
