can only recycle nutrients from soil depths. All trees can sequester carbon, but some trees grown for<br />

wood will be cut; others may be regularly pruned for livestock feeds and never reach a significant size.<br />

Recent literature includes guidelines for the use of sustainable land management (SLM) practices<br />

for agriculture and other land uses, such as integrated soil fertility management, soil conservation<br />

methods, conservation agriculture, rainwater harvesting and irrigation management and integrated<br />

crop-livestock management. The following are two key publications:<br />

• Sustainable Land Management Sourcebook (World Bank 2008)<br />

• Using Sustainable Land Management Practices to Adapt to and Mitigate Climate Change in<br />

Sub-Saharan Africa (Woodfine 2009)<br />

There is also a Web portal that contains practical examples of SLM from around the world: the World<br />

Overview of Conservation Approaches and Technologies (WOCAT) at http://www.wocat.net.<br />

In this section, we touch briefly on two practices: sustainable rangeland and forest management.<br />

Pastoralism and Rangeland Management<br />

Many important practices can improve productivity and reinforce environmental stability for livestock<br />

and rangeland management. These include sustainable grazing management, which focuses on<br />

recovery periods for grasses and other vegetation; reduced use of rangeland fires to prevent loss<br />

of soil carbon; and silvopastoral management, which involves balancing vegetation and biomass<br />

to meet a variety of needs (Woodfine 2009). Most management techniques are designed around<br />

regenerating resources to facilitate fresh grass and shrub biomass growth. In more intensive systems<br />

or in strategically placed sites, purposeful planting of grasses and shrubs can also be undertaken,<br />

benefiting from research on improved species and establishment methods. Although overstocking<br />

is often cited as a culprit behind apparent rangeland degradation, the holistic approach to grazing<br />

management emphasizes the importance of rotations and recovery periods for the resource; if these<br />

are done properly, they can greatly improve productivity and carrying capacity.<br />

Sustainable Forest Management<br />

Conversion of forest lands into cultivated mosaics has had adverse effects on water flows, has greatly<br />

reduced plant and animal biodiversity, and has been a chief emitter of greenhouse gases. While<br />

some forests need to be conserved and protected, many new examples of integrated management<br />

involve sustainable use of forests and forest products. According to FAO (2010a), sustainable forest<br />

management aims to ensure that the goods and services derived from the forest meet current<br />

needs while securing their continued availability and contribution to long-term development. Certain<br />

silvicultural practices guide governments and other managers on sustainable harvesting and offtake<br />

for various species. New management models include some form of local ownership or rights,<br />

through which local communities have vested interests in the long-term health of the forest. The<br />

rights can vary from home consumption of forest products (e.g., fuelwood) to marketing specified<br />

products (e.g., fruits) to establishment of eco-tourism businesses.<br />
