In many developing countries, smartphone and internet usage has become a revolution for the population and has opened up many possibilities to use new services for communication purposes. For researchers and development organizations, it is now possible to engage more directly with beneficiaries during the implementation phase of a project. However, many regions still face the problem of a non-existent or unreliable internet connection, which is why mobile applications have to be able to work offline as well as online.

This research was undertaken as a Ph.D. dissertation (Stanford University) in conjunction with the ILCA programme in Niamey, Niger. The objective of the research was similar to that of the World Bank studies: to test how land tenure affects land-improving investment, agricultural productivity and resource management. The standard hypothesis is that land tenure that is non-exclusive insecure or non-transferable will lead to under-investment and depressed factor mobility.

In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

An analysis of the effects of climate change on 22 critical agricultural commodities and three important natural resources in the developing world reveals a number of cross-cutting themes: The world’s agricultural systems face an uphill struggle in feeding a projected nine to ten billion people by 2050. Climate change introduces a significant hurdle in this struggle.
- Securing and maintaining necessary levels of calories, protein and nutrients for populations around the world will be an exceptional challenge.

Reducing emissions from deforestation and degradation (REDD ) should focus on places where such emissions occur. Protected Areas (PAs) are, in theory, protected and hence, should have no emissions associated with land use/land cover change. In practice rotection is incomplete. Can PAs be included in REDD schemes? Can 'paper parks' be included that exist on paper rather than in reality? How concrete should threats be before we call carbon (C) protection 'additional'? The dilemma may be more manageable if protected areas are included in a broader landscape approach to REDD.

Recycling and reuse of treated wastewater are an important part of the sanitation cycle and critical in an environment such as urban India with decreasing freshwater availability and increasing costs for delivering acceptable quality water, often from far distance. This report has been developed as a possible guidance document for the Indian government and gives substantial focus to the financial and economic benefits of wastewater recycling from the perspective of public spending.

A large number of governance interventions are being developed in order to reduce deforestation and enhance the sustainability of commodity

supply chains across the tropics. The extent to which individual agricultural commodity supply chain interventions can achieve scale, and

environmental or social objectives, depends in part on the ways in which those interventions interact with other interventions. We use a casestudy

of the new Sustainable Agriculture Network (SAN) cattle certification program in Brazil to explore the different ways in which governance
