Investments that reduce food loss and waste can deliver big wins on two pressing issues of our time: food security and environmental sustainability, according to a new World Bank report. But the results are not automatic -- countries need well-targeted solutions.

Influenced by international trends, as well as in response to population, climate, resource and development needs, the standards, norms, mechanisms and incentives in natural resources law at the national level have evolved in recent years. Natural resources laws are influenced by developments in the international arena, either through international treaties that are binding or through ‘soft law’ instruments that are not legally binding but nevertheless have widespread adherence among governments, or that provide principles that guide and shape national legislation.

Unless countries can manage to mobilize millions of land users to invest their scarce resources in protecting regenerating trees, the battle against land degradation cannot be won. These experiences from Niger show that hundreds of thousands of smallholder farm families have substantially increased tree cover on their farm land by investing in the management of on-farm trees. This has improved their production systems and their livelihoods. There is no reason to believe that similar success cannot be achieved in many more countries throughout African drylands and sub-humid area.
