Land degradation WHAT IS LAND DEGRADATION? Land degradation is a broad term that can be applied differently across a wide range of scenarios. It is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is the reduction in the capacity of the land to provide ecosystem goods and services and assure its functions over a period of time for the beneficiaries of this. Increased population pressures and excessive human expansion into drylands during long wet periods leave an increasing number of people stranded there during dry periods. CAUSES OF LAND DEGRADATION: Land degradation is a global problem, largely related to agricultural use. The major causes include: Land clearance, such as clearcut- ting and deforestation; Agricultural depletion of soil nutrients through poor farming practices; Livestock farming that includes over- grazing and overdrafting; Inappropriate irrigation and overdrafting; Monoculture that destabilises the local ecosystem; and Urban sprawl and commercial development. IMPACT: There are four main ways of looking at land degradation and its impact on the environment around it: A temporary or permanent decline in the productive capacity of the land: This can be seen through a loss of biomass, a loss of actual or potential productivity, or a loss or change in vegetative cover and soil nutrients; Action in the land’s capacity to provide resources for human livelihoods: This can be measured from a baseline of previous land use; Loss of biodiversity: A loss of range of species or ecosystem complexity as a decline in the environmental quality; and Shifting ecological risk: Increased vulnerability of the environment or people to destruction or crisis. This is measured through a baseline in the form of pre-existing risk of crisis or destruction. GOVERNMENT INTERVENTION: Over the year, the South African government has spent millions of rands on land rehabilitation projects, mostly funded through the LandCare conditional grant. agriculture, forestry & fisheries Department: Agriculture, Forestry and Fisheries REPUBLIC OF SOUTH AFRICA.

CHAPTER 13 Groundwater Collective Management Systems: the United States Experience
13-Smith.qxd 02-10-2002 19:59 Pagina 257 CHAPTER 13 Groundwater collective management systems: the United States experience Z.A. Smith Northern Arizona University, Flagstaff, Arizona, USA [email protected] ABSTRACT: Groundwater management in the USA is diverse and decentralized making generaliza- tions sometimes difficult. In many areas groundwater is managed well under permit systems that pre- vent wasteful overuse and allow planned development. In other areas individuals are free to pump water with few restrictions and sometimes with wasteful consequences. This chapter provides an overview of collective groundwater management systems used in the USA by summarizing the types of systems in place and the advantages and disadvantages of each system. It concludes with an exam- ination of what can be learned from the groundwater management experience in the USA and sug- gestions for the development of future groundwater management systems. 1 INTRODUCTION others very little groundwater is used (Table 1 gives a state-by-state breakdown of groundwater The rules governing groundwater use in much of use). the USA and the world bring to mind the state- ment in Plato’s Republic “I declare justice is 1.2 Role of the national government nothing but the advantage of the stronger”. Is this how things should be? In much of the USA To examine in a comprehensive manner the and the rest of the world this is how it is. In this experience of managing groundwater in the chapter we will examine the experience of the USA is a daunting task. The first thing that one USA in the collective cooperation and manage- must understand is that there is no national ment of groundwater resources.

Overdrafting Toward Disaster: a Call for Local Groundwater Management Reform in California’S Central Valley
Comments Overdrafting Toward Disaster: A Call for Local Groundwater Management Reform in California’s Central Valley By PHILIP LAIRD* Introduction MY GRANDFATHER has been a farmer all of his life. He has grown raisins in Selma, California for over seventy years. Like most crops, raisins need good soil, sunshine, and a steady flow of water. Without any one of these elements, the vines will die, and the crop will be a loss. Water, as one can imagine, ends up being the most problematic resource. There are no rivers or canals that run by my grandfather’s property. Thus in order to nourish his vineyard and make the vines grow, he has to pump groundwater. My grandfather first began using his pump in the 1930s. At that time, the well he used only had to extend down eighteen feet to reach the water table and provide suffi- cient water to his ranch. As the years went by though, the water table dropped, and he had to spend more and more money digging deeper wells and pumping from greater depths. Today, in order to reach the water table, my grandfather’s well is ninety feet deep. This story is not unique to my grandfather. The water table throughout California is dropping at an alarming rate, and thus far, efforts to seriously curb this depletion are minimal at best. Currently, groundwater in California provides approximately 30% of the state’s * J.D.

OVERCOMING THE “TRAGEDY Underground Aquifers: A Classic Case of the “Tragedy of the Commons” OF THE COMMONS” In certain parts of the world, the strong pressure on water resources leads to an increasing overexploitation of aquifers. Sustainable extraction means withdrawing less water than the amount the aquifers need to replenish. If the withdrawal rate exceeds the natural recharge rate, the water table will gradually The amount of water drop, as is the case in Mediterranean countries, where overexploitation of the extracted from aquifers water resource occurs either at a national level (Algeria, Jordan, Libya), or at worldwide has increased more localized scales (France, Greece, Italy, Morocco, Tunisia). threefold in the past fifty years, leading to an Within the classification of economic goods, and with a water withdrawal regime aggravated overdraft of that often amounts to de facto open access, groundwater resources belong to these common resources. the category of common goods: they are non-excludable (i.e., users can not This “pumping race” be prevented access to the good), unlike private goods, and they are usually brings about major adverse rivalrous goods (i.e., the use of the good by one user can lower the quantity economic, environmental available for the other users), unlike public goods. and social impacts.

Land subsidence in the San Joaquin Valley has been going on for years, but in 2014 the emergency drought proclamation by Governor Edmund G. Brown Jr. triggered the development of a subsidence monitoring report. That year, California also passed major groundwater legislation. The report included data from a 2017 NASA Jet Propulsion Laboratory paper indicating that land in the San Joaquin Valley has subsided 28 feet since the 1920s.

J. L. & PUB. POL’Y 467 (2006) www.NationalAgLawCenter.org GROUNDWATER MANAGEMENT IN TEXAS: EVOLUTION OR INTELLIGENT DESIGN? Ronald Kaiser" I. INTRODUCTION Groundwater management in Texas is a work in progress. It is evolving from a patchwork of judicial decisions dealing with landowner conflicts over well interference to incremental regulatory changes by legislatively established local groundwater management districts. Except for the Edwards Aquifer Authority, which arguably has elements of intelligent statutory design, the remaining groundwater districts have evolved from planning and education activities to varying degrees of aquifer regulation. The state's burgeoning population growth, recurrent droughts, groundwater mining, restrictions on surface water transfers, increased water demand by cities, rural fears associated with groundwater transfers, and endangered species are the driving factors in this regulatory transfonnation. I Although it is especially important for irrigated agriculture, groundwater also provides drinking water for a number of Texas cities. 2 The Texas Water • Professor, Recreation, Park and Tourism Sciences, Texas A&M University, College Station, Texas.. 1.
