Rayalaseema region (rain-shadow zone) in Andhra Pradesh state is a hot and dry region experiencing frequent meteorological droughts. This region has only about 30% of the cropped area irrigated, and rest of it is dependent on rain-fed cultivation, which is susceptible to the vagaries of monsoon. The region is socio-economically relatively backward and has poor water security.

This study evaluates the benefits and costs of three interventions affecting household air pollution caused by the use of solid fuels for cooking. The interventions studied are Promotion of improved biomass cookstoves, Free provision of LPG connection to poor households and A 50% reduction of subsidies to LPG fuel. Benefits and costs are presented as a ratio of annualized benefits and annualized costs (benefit-cost ratios) over the expected useful life of each intervention.

Expansion of irrigation in the desert region of western Rajasthan through lifting canal water into diggies (small pond to store the canal water supply that addresses the reliability issue) and using it for irrigation through sprinkler system and selection of crops that are less water-intensive enables farmers to take up crop production even in undulating land, having saline groundwater, thereby reducing irrigation water application requirements.

When it comes to cooking indoors over open fires, the harmful health effects can be equal to smoking two packs of cigarettes a day. This indoor air pollution plagues nearly nine out of every 10 Bangladeshi households, which use wood and other biofuels to cook inside.

The last two decades have seen a large body of evidence of substantial health effects for long term exposure to air pollution – especially fine particulate matter – be it in the form of outdoor ambient air pollution (AAP) or household air pollution (HAP) from the use of solid fuels. There are compelling arguments that air pollution should feature in a new set of post-2015 development goals.

As realization has grown of the impact of air pollution, so too has it become clear that the effects of individual pollutants (particles, SO2, NOx, NH3 and volatile organics) are linked and that they should not be considered in isolation. Health has become the prime driver of air pollution policies in North America and Europe since the mid-1990s, following new analysis that found detectable effects at levels previously considered ‘safe’ and no evidence for an exposure threshold for fine particulates.

The post 2015 agenda seeks to replace the MDGs with new goals that “move beyond meeting basic human needs and promote dynamic, inclusive and sustainable development”. There has been an active debate on what precisely these goals should be and what indicators should be used to track them. The Zero Draft of proposed goals and targets from the UN Open Working Group includes under Goal 14 ten targets focused on marine resources, while Goal 15 has 12 targets dealing with terrestrial natural resource issues.

This perspectives paper explores in greater depth part of the cost-benefit analysis undertaken by Markandya, particularly for Sustainable Development Goal 15.2: By 2020, promote the implementation of sustainable management of all type of forests, halt deforestation, restore degraded forests, and increase afforestation and reforestation by x% globally.

This perspective paper makes a proposal for improved methodologies for conducting large scale assessments of the costs and benefits of meeting targets for biodiversity and ecosystem change. This is driven by the recognition that currently applied approaches, such as those used by Markandya in the challenge paper, do not produce sufficiently accurate information for use in cost-benefit analysis. For example, the enormous span of results for the wetland program implies that we cannot estimate even the order of magnitude of benefits.

The biggest environmental problem in the world is, perhaps surprisingly, air pollution. Perhaps even more surprisingly, it has been declining for past 110 years. This is because most air pollution deaths are caused by indoor pollution from cooking and heating with dirty fuels.

Much has been written and said on the loss of biodiversity that we have been experiencing in recent decades. Species are estimated to be going extinct at rates 100 to 1000 times faster than in geological times. Moreover there is reason to believe that these extinctions are associated with economic and social losses.
